Description

  The present invention relates to a muscular electrical stimulation device and a method of using the muscular electrical stimulation device.

  One example of a device for training muscles is a muscle electrical stimulation device. A muscle electrical stimulator applies an electric current to muscle fibers to tension and relax muscles. This is expected to enlarge the muscles. For example, a muscular electrical stimulation device as described in Patent Document 1 has been proposed. The electrical muscular stimulation device described in Patent Literature 1 is attached to a human body using the adhesiveness of a gel pad attached to a main body and used in that state.

JP 2017-6644 A

The present inventor has obtained the following recognition regarding the electrical muscular stimulation device.
It is conceivable that the muscle electrical stimulation apparatus applies electrical stimulation to the muscles of these parts by attaching a gel pad having adhesive force to a wearing part of the user's body such as the abdomen, upper limb, and lower limb. In this case, it is conceivable that the muscular electrical stimulation device to which the gel pad having adhesive force is attached is attached to the mounted portion by the adhesive force of the gel pad. In order to obtain a training effect, it is desirable to use the muscle electrical stimulation device continuously for a certain period of time. During this time, if the user suddenly moves, it is conceivable that a part of the muscular electrical stimulation device is peeled off from the mounted portion and floats.

In order to suppress the lifting of the muscular electrical stimulation device, it is conceivable to increase the size of the gel pad or increase the adhesive strength. However, when the size of the gel pad is increased, the gel pad protrudes greatly from the electrical muscular stimulation device, and it is considered that the management becomes complicated, such as the possibility that clothes or foreign matters are stuck on the portion. In addition, when the adhesive force is increased, it is considered that the gel pad is less likely to be peeled off from the wearing portion and the electrical muscular stimulation device, and the usability is deteriorated.
From these, the present inventor has recognized that the electrical muscular stimulation device has a problem to be improved from the viewpoint of suppressing the lifting from the mounted portion.

  This invention is made | formed in view of such a condition, The objective is to provide the muscular electrical stimulation apparatus which can suppress the lifting from a to-be-mounted part.

  In order to solve the above-described problems, an electrical muscular stimulation device according to an aspect of the present invention includes a main body having a mounting surface that is mounted along the periphery of a mounted portion of the body. The mounting surface extends in the X direction that circulates around the mounted portion, and is disposed apart from each other in the main body portion, and is separated from the pair of electrode portions for flowing current to the mounted portion, in the X direction. And a pair of connecting portions for connecting an attracting member for attracting the main body portion toward the mounted portion side, and the attracting member is disposed in the X direction on the opposite side of the mounted portion from the main body portion. It extends and spans between a pair of connecting portions.

  Another aspect of the present invention is a method of using a muscular electrical stimulation device. This method is a method of using a muscle electrical stimulation device mounted on a body wearing portion, and the muscle electrical stimulation device is a main body portion having a first hole portion and a second hole portion that are provided apart from each other. The first hole portion and the second hole portion are configured to be able to connect an attracting member for attracting the main body portion toward the mounted portion side, and the attracting member is a surface that is detachably attachable A belt-shaped first member and a second member provided with fasteners are included. The method includes connecting a portion on one end side of the first member to the first hole portion, connecting the second member to the second hole portion, and folding back to the other end side of the first member. Forming a portion, disposing the main body portion on the mounted portion, and connecting the folded portion to the second member through the side opposite to the main body portion of the mounted portion.

  The inventor considered the electrical muscular stimulation device attached to the wearing part of the body from the viewpoint of suppressing lifting from the wearing part, and obtained the following knowledge.

  It is conceivable that the user exercises with high intensity, such as training another body part, with the muscular electrical stimulation device attached to the wearing part using the adhesiveness of the gel pad. If exercise with high strength is performed with the muscular electrical stimulation device attached, a part of the muscular electrical stimulation device may be peeled off from the attached portion and lifted up. For this reason, it can be considered that the user who is training has a burden feeling that behavior is restricted, and that the training by the electrical muscular stimulation device is troublesome.

  From these, the present inventor has devised a configuration in which an attracting member that draws the main body portion of the muscular electrical stimulation device toward the attached portion side is provided in order to suppress the lifting of the muscular electrical stimulation device. By pulling the main body part toward the mounted part side by the attracting member, the possibility that the main body part is lifted can be reduced. For example, a connecting portion is provided in the vicinity of both end portions in the circumferential direction on the mounted portion of the main body portion, and the portions on both sides of the attracting member that are passed through the opposite side of the mounted portion on the side where the main body portion is mounted are It is conceivable to connect to the connecting part. In this case, the vicinity of both end portions of the main body portion is attracted toward the mounted portion side, so that the main body portion can be prevented from rising.

  The drawing member is not particularly limited as long as it has the property of allowing the opposite side of the mounted portion to pass through and connecting to the connecting portion of the main body portion. As an example, a strip-shaped member, a string-shaped member, a wire-shaped member, or the like made of various materials can be adopted as the attracting member.

  As an example, consider a case where the attraction member is made of a cloth band-shaped member and the connecting portion of the main body includes a hole. In this case, one end of the belt-shaped member is tied through one hole, the main body is attached to the mounted portion, the other end of the belt-shaped member is passed through the opposite side of the mounted portion, and the other end is connected to the other hole. It is possible to tie it through. Further, it is conceivable to connect the end portion of the band-shaped member and a predetermined portion with the surface fastener in a state where the band-shaped member is provided with the surface fastener and both end portions of the band-shaped member are passed through the respective hole portions. In this case, it is possible to reduce the trouble of mounting the electrical muscular stimulation device on the mounted portion.

  It is desirable that the mounting effort is less. Accordingly, one or both of the connecting portions may be provided with a hook-and-loop fastener. In this case, since the belt-like member can be connected to the hook and loop fastener provided in one or both of the connecting portions, the belt-like member can be easily attached and detached at that portion. The hook-and-loop fastener may be provided on the connecting portion by various means. As an example, the hook-and-loop fastener may be fixed to the connecting portion by passing a member provided with the hook-and-loop fastener through the hole of the connecting portion and connecting the end portions with the hook-and-loop fastener.

  Since the size of the mounted portion varies depending on the person, the length of the band-shaped member that can be adapted to the mounted portion is considered to vary greatly depending on the individual. Therefore, the belt-shaped member may be formed with a folded portion that is maintained by a hook-and-loop fastener. The folded portion may be configured to be connected to the connecting portion by a hook-and-loop fastener. In this case, the belt-like member can be brought into a state suitable for the size of the mounted portion by changing the position of the folded portion. Further, once the position is adjusted and the folded portion is formed, the convenience can be improved because the same user can use it as it is next time.

  If the band-like member is squeezed too strongly at the time of wearing, there is a concern that the blood flow in the attached part is inhibited and the body is adversely affected. Therefore, the shear strength of the hook-and-loop fastener may be formed so as to be disconnected by applying the force of the arm. The shear strength of the hook-and-loop fastener may be formed so as to prevent the band-shaped member from dropping due to its own mass.

  Each embodiment has been devised based on such thought, and the specific configuration will be described below.

Hereinafter, the present invention will be described based on preferred embodiments with reference to the drawings. In the embodiment and the modification, the same or equivalent components and members are denoted by the same reference numerals, and repeated description is appropriately omitted. In addition, the dimensions of the members in each drawing are appropriately enlarged or reduced for easy understanding. In addition, in the drawings, some of the members that are not important for describing the embodiment are omitted.
In addition, terms including ordinal numbers such as first and second are used to describe various components, but this term is used only for the purpose of distinguishing one component from other components. However, the constituent elements are not limited.

The training system 100 includes a muscular electrical stimulation device 10 and a remote control device 12. The electrical muscular stimulation device 10 according to the first embodiment is worn on the user's abdomen 3. The muscle electrical stimulation device 10 applies electrical stimulation to the muscles of the abdomen 3. In addition, the muscular electrical stimulation device 10 detects the operation status of the muscular electrical stimulation device 10 and outputs the detection result to the remote control device 12 by wireless or wired.

  The remote control device 12 is various terminals operated by a user. The remote control device 12 may be, for example, a PC, a tablet terminal, or a smartphone. The remote control device 12 controls the operation of the muscular electrical stimulation device 10 in accordance with a user operation. The remote control device 12 receives the detection result of the operation state from the electrical muscular stimulation device 10. As an example, the muscular electrical stimulation device 10 transmits device information to the remote control device 12 and receives operation information from the remote control device 12 by wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). May be.

  The remote control device 12 displays a predetermined display on the touch panel based on the operation status acquired from the muscular electrical stimulation device 10. The user can recognize the operation status of the electrical muscular stimulation device 10 by viewing the display on the touch panel of the remote control device 12. The remote control device 12 can detect a user operation with the touch panel. The user can input a predetermined touch operation by a tap operation that is lightly pressed once with a finger on the touch panel or a swipe operation that is moved in a certain direction while pressing the touch panel with a finger. The remote control device 12 can generate operation information based on a user's touch operation and transmit it to the electrical muscular stimulation device 10.

  As shown in FIG. 1, the muscular electrical stimulation device 10 according to the first embodiment is used by being attached to the abdomen 3 of the body 2. The electrical muscular stimulation device 10 has a mounting surface 10b that is a surface to be mounted along the periphery of the abdomen 3 when mounted. The mounting surface 10b extends in an X direction that circulates around the abdomen 3 and a Y direction that is orthogonal to the X direction. Note that the X direction and the Y direction only define the surface direction of the mounting surface 10b, and the mounting surface 10b may include a portion extending in a direction inclined with respect to the Y direction. Although not shown in FIG. 1, the direction orthogonal to the X direction and the Y direction is defined as the Z direction. The Z direction is orthogonal to the mounting surface 10b.

  In the example of FIG. 1, the electrical muscular stimulation device 10 is mounted such that the Y direction of the mounting surface 10 b is along the longitudinal direction of the body 2 and the X direction of the mounting surface 10 b is around the abdomen 3. It is desirable that the electrical muscular stimulation device 10 be mounted by aligning a front concave portion of the main body 20 described later with a straight line L1 in the Y direction passing through a navel (not shown). Hereinafter, the Y direction may be referred to as an upward direction or a downward direction, and the Z direction may be referred to as a thickness direction. Such notation of the direction does not limit the use posture of the electrical muscular stimulation device 10, and the electrical muscular stimulation device 10 can be used in an arbitrary posture.

  The electrical muscular stimulation device 10 includes a main body 20 and a belt member 50. The main body 20 rotates around the front side of the abdomen 3, and the belt member 50 is connected to the other end of the main body 20 around the back side of the abdomen 3 from one end of the main body 20 in the circumferential direction. The belt member 50 is an attracting member that draws the main body portion 20 toward the abdomen 3 side, which is a mounted portion. The belt member 50 will be described later.

  The main body portion 20 includes a front portion 22, a pair of extending portions 26, a control unit 30, and a belt connecting portion 42. The front part 22 is attached to the front of the abdomen 3. The front electrode portion 22 is provided with a front electrode portion configured to flow a current along the X direction to the rectus abdominis muscle 4. The pair of extending portions 26 extend from the front portion 22 to both sides in the circumferential direction. Each of the pair of extending portions 26 is provided with a side electrode portion configured to cause a current to flow through the oblique oblique muscle 5 along the circumferential direction. The control unit 30 is an electronic unit that supplies a muscle stimulation voltage to the front electrode portion and the side electrode portion. The belt connecting portion 42 is a member that connects the two belt members 50 to the main body portion 20. The front electrode portion and the side electrode portion include a sheet-like electrode that supplies a muscle stimulation voltage to the mounted portion. This sheet-like electrode can be formed by printing a conductive material such as silver paste or by etching.

  FIG. 3 is a front view of the muscular electrical stimulation device 10. FIG. 4 is a plan view of the muscular electrical stimulation device 10. FIG. 5 is a rear view of the muscular electrical stimulation device 10. FIG. 6 is a rear view showing an example of the arrangement of the lead portion 37 of the muscular electrical stimulation device 10. FIG. 7 is a rear view showing an example of the arrangement of the electrode portions of the muscular electrical stimulation device 10. 3-7 is the figure which unfolded the muscular electrical stimulation apparatus 10, and looked at the mounting surface 10b of each part from the front. As shown in FIGS. 3 to 7, in the unfolded state, the X direction corresponding to the circumferential direction of the body 2 and the Y direction corresponding to the vertical direction of the body 2 are linearly shown as arrows X and Y. .

(Main body)
The main body 20 may have a layer structure. As an example, the main body portion 20 includes a first base material 14, a second base material 15, and a cover member 16. The 1st base material 14 is a member with which the body 2 is mounted | worn, and exhibits a flat sheet form at the time of expansion | deployment. A mounting surface 10 b that contacts the abdomen 3 is provided on the back surface of the first base material 14. The first substrate 14 has an opening 14b that exposes the front electrode portion 32 and the side electrode portion 36 to the mounting surface 10b side. The first base material 14 may be configured by combining a plurality of members. As for the 1st base material 14 of this example, the part corresponding to the front part 22 and the part corresponding to a pair of extension part 26 are comprised integrally. The electrical muscular stimulation device 10 of this example can increase the durability of the lead portion 37 as compared with the case where the first base material 14 is not provided.

  The 2nd base material 15 is a member which supports the front electrode part 32, the side electrode part 36, and the lead part 37, and exhibits a flat sheet shape at the time of expansion | deployment. The second base material 15 may be configured by combining a plurality of members. In the second base material 15 of this example, a portion corresponding to the front portion 22 and a portion corresponding to the pair of extending portions 26 are integrally formed. A front electrode portion 32 and a side electrode portion 36 are provided on the back surface of the second base material 15. The front electrode part 32 and the side electrode part 36 can be formed, for example, by printing a conductive material such as silver paste. The front electrode part 32 and the side electrode part 36 may be formed by etching. The second base material 15 is provided with a lead portion 37 that is electrically connected to the front electrode portion 32 and the side electrode portion 36. The lead part 37 can be formed, for example, by printing a conductive material such as silver paste. The lead part 37 may be formed by etching. The lead part 37 may be referred to as a wiring pattern.

  The cover member 16 is a member laminated on the opposite side of the second base material 15 from the first base material 14. The cover member 16 includes a flat sheet-like sheet portion 16b when unfolded, and an edge cover portion 16c extending from the outer edge of the sheet portion 16b toward the second base material 15 in the thickness direction (Z direction). A control unit 30 is provided on the outer surface portion 10 c of the seat portion 16 b of the cover member 16. The cover member 16 may be configured by combining a plurality of members. The cover member 16 of this example is configured to integrally cover the front portion 22 and the pair of extending portions 26.

  If the 1st base material 14 and the 2nd base material 15 are formed thinly, the outer periphery edges 14e and 15e will also become thin. In the state where the muscular electrical stimulation device 10 is mounted on the body 2, it is conceivable that the outer peripheral edges 14e and 15e come into contact with the body and give an unpleasant tactile sensation to the user. Therefore, the cover member 16 of the present example includes an edge cover portion 16c that covers the outer peripheral edges 14e and 15e of the first base material 14 and the second base material 15. In this case, since the edge cover portion 16c covers the outer peripheral edges 14e and 15e, the contact area between the main body portion 20 and the body 2 is increased, and the tactile sensation given to the user can be improved. The edge cover portion 16c of this example is formed in a band shape surrounding the outer peripheral edges 14e and 15e. The cover member 16 of this example can increase the rigidity compared to the case where the edge cover portion 16c is not provided. Moreover, when the muscular electrical stimulation apparatus 10 is worn on the body 2, the outer peripheral edges 14e and 15e may bite into the skin. By providing the edge cover part 16c, the irritation | stimulation and pain to the skin at that time can be suppressed.

  The material of the first base material 14 and the second base material 15 is not particularly limited as long as it is a material having insulation properties and flexibility enough to be wound around the body. The first base material 14 and the second base material 15 in this example are formed of an elastomer such as polyethylene terephthalate resin. The material of the cover member 16 is not particularly limited as long as it is a material having insulating properties and flexibility enough to be wound around the body. As an example, the cover member 16 can be formed of a resin material harder than the first base material 14 and the second base material 15. The cover member 16 of this example is formed of an elastomer such as silicon resin. In this case, the cover member 16 protects the first base material 14 and the second base material 15, suppresses damage due to handling, and can impart appropriate rigidity to the main body portion 20. The cover member 16 made of silicon resin can cover from the front of the abdomen 3 to the side. By using the muscular electrical stimulation device 10, the body temperature is transmitted to the silicon resin and stored there. For this reason, it feels warm during use and is expected to improve blood flow by the thermal effect.

(Front)
The front part 22 is attached at a position corresponding to the rectus abdominis muscle 4 on the front side of the abdomen 3. The front part 22 is provided with a front electrode part 32 that is configured to cause a current to flow through the rectus abdominis muscle 4 along the circumferential direction. The front portion 22 extends in the X direction and the Y direction and is formed thin in the Z direction. The front portion 22 has a shape that can be regarded as a substantially rectangular shape having a dimension Y1 in the Y direction and a dimension X2 in the X direction in a front view. Hereinafter, in the present specification, the shape that can be regarded as a substantially rectangular shape includes a shape including a pair of opposite sides having a length of 30% or more of the total length. The longitudinal direction of the front part 22 is arranged along the X direction.

  It is conceivable that between the muscle electrical stimulation device 10 and the abdomen 3 is steamed due to sweating during training. Therefore, the front portion 22 of this example is provided with a plurality of (for example, four) vent holes 23g. As shown in FIG. 3, the vent hole 23 g is provided at a position surrounding the control unit 30 while avoiding the electrode and the lead portion. In this case, the stuffiness between the muscular electrical stimulation device 10 and the abdomen 3 is alleviated as compared with a configuration having no ventilation hole. Moreover, the flexibility of the front part 22 improves by providing the vent hole 23g. The flexibility of the front portion 22 can be adjusted by changing the number and arrangement of the air holes 23g.

  The control unit 30 may be provided at a substantially central portion in the X direction and the Y direction of the front portion 22. The front portion 22 may be formed symmetrically with respect to the control unit 30 in the X direction and the Y direction. In particular, the front portion 22 may be formed symmetrically with respect to a straight line extending in the Y direction with respect to the center of the control unit 30 in the X direction. By having such a symmetric shape, when the muscular electrical stimulation device 10 is used for the upper limb or the lower limb, it can be used in accordance with each part only by reversing the direction of the device.

(Front recess)
From the viewpoint of facilitating wearing, it is desirable that the muscular electrical stimulation device 10 can easily determine the center position of the front portion 22 in the X direction. Therefore, the electrical muscular stimulation device 10 of this example is provided with a front concave portion 23 at the center position of the front portion 22. The front recessed part 23 is provided in the position which bisects the front part 22 in the X direction in the side parts 22b and 22c of the front part 22 in the Y direction. FIG. 3 shows a bisector M1 that bisects the front portion 22 in the X direction. The front recess 23 is recessed in the Y direction. The front concave portion 23 of this example includes a first concave portion 23b and a second concave portion 23c provided on the side portions 22b and 22c on both sides in the Y direction.

  It is desirable for the front recess 23 to be able to identify the center position by the sense of touch of the fingertip in addition to vision. Therefore, the front concave portion 23 of this example has a frontage in the X direction that allows a fingertip to be hung. If the front concave portion 23 is too shallow, the discriminability of the center position may be lowered. From this point of view, the depth of the front concave portion 23 of this example may be set to a size that can accept a quarter of the last fingertip.

(Boundary recess)
In many cases, the peripheral surface of the abdomen 3 is formed of a curved surface that changes in a complicated manner. For this reason, when the main body portion 20 is attached to the abdominal portion 3, the extending portion 26 is attached to the abdominal portion 3 while being twisted with respect to the front portion 22, as shown in FIG. 1. If the extension part 26 is difficult to twist, a twisting moment generated between the front part 22 and the extension part 26 increases, and the feeling of wearing on the abdomen 3 is reduced. Therefore, in this example, a boundary concave portion 25 that is recessed inward in the Y direction is provided at a boundary portion between the front portion 22 and the pair of extending portions 26 on the side portion in the Y direction of the main body portion 20. In this case, compared with the case where the boundary recessed part 25 is not provided, the extension part 26 becomes easy to twist, and the mounting | wearing feeling to the abdominal part 3 improves.

  The boundary concave portion 25 of this example includes a first boundary concave portion 25b and a second boundary concave portion 25c provided on the side portions 26b and 26c on both sides in the Y direction. In this case, compared with the case where one boundary recessed part is not provided, the extension part 26 becomes easy to twist, and the mounting | wearing feeling to the abdominal part 3 further improves. The boundary recess 25 has a shape that approaches the bisector M1 as it goes back. That is, the boundary recess 25 is formed to be inclined with respect to the X direction. In this case, since the deformation region of twist is expanded in the X direction compared to the case where no inclination is provided, the stress due to twist can be dispersed in the X direction. As shown in FIG. 7, the dimension Y4 in the Y direction of the portion closest to the Y direction between the first boundary recess 25b and the second boundary recess 25c is larger than the dimension Y5 described later and smaller than the dimension Y2 described later.

(Lead part)
As shown in FIG. 6, the lead portion 37 in this example is provided on the back surface 15 b of the second base material 15. The lead portion 37 includes a wiring 37b, a wiring 37c, a wiring 37d, a wiring 37e, a wiring 37f, a wiring 37g, a bending portion 37h, and a bending portion 37j. The wiring 37b electrically connects the terminal 38b and the electrode group 32b. The wiring 37c electrically connects the terminal 38c and the electrode group 32c. The wiring 37d electrically connects the terminal 38d and the first electrode 36b. The wiring 37e electrically connects the terminal 38e and the second electrode 36c. The wiring 37f electrically connects the terminal 38d and the first electrode 36d. The wiring 37g electrically connects the terminal 38e and the second electrode 36e. The curved portion 37h is provided corresponding to the front recess 23. The curved portion 37j is provided corresponding to the boundary recess 25.

  If the front concave portion 23 is provided, it is conceivable that the lead portion 37 is too close to the outer peripheral edge of the second base material 15 at that portion. Therefore, the lead portion 37 of this example has a curved portion 37 h that curves inward in the Y direction corresponding to the front concave portion 23. By having the curved portion 37h, the front concave portion 23 can be formed into a desired shape.

  If the front concave portion 23 is provided, stress concentrates on the portion of the main body portion 20 where the front concave portion 23 is provided, and there is a risk that defects such as cracks may occur in that portion. Therefore, in the present example, a thick portion 24g formed in the thickness is provided in the portion of the main body portion 20 where the front concave portion 23 is provided. The shape of the thick portion 24g can be set by simulation according to the desired durability.

  If the boundary concave portion 25 is provided, it is conceivable that the lead portion 37 is too close to the outer peripheral edge of the second base material 15 at that portion. Therefore, the lead portion 37 of this example has a curved portion 37j that curves inward in the Y direction corresponding to the boundary recess 25. By having the curved part 37j, the boundary recessed part 25 can be made into a desired shape.

  If the boundary concave portion 25 is provided, stress concentrates on the portion of the main body portion 20 where the boundary concave portion 25 is provided, and there is a risk that defects such as cracks may occur in that portion. Therefore, in this example, a thick portion 25g formed to be thick is provided in a portion of the main body portion 20 where the boundary concave portion 25 is provided. The shape of the thick portion 25g can be set by simulation according to desired durability. In this example, the cross section of the thick portion 25g cut along the surface along the Z direction rises upward from the edge of the boundary recess 25 to form the top, and the thickness gradually decreases from the top toward the inside. have.

As shown in FIG. 7, the front electrode portion 32 is arranged in an arrangement region 32 a having a dimension X3 in the X direction and a dimension Y3 in the Y direction. The front electrode portion 32 may include a plurality of electrodes that are spaced apart by a distance X6 in the X direction. The distance X6 may be set corresponding to the width of the rectus abdominis muscle 4. The front electrode portion 32 of this example includes a pair of electrode groups 32 b and 32 c that are spaced apart in the X direction corresponding to the circumferential direction of the abdominal portion 3. The electrode groups 32b and 32c are arranged with a distance X6 apart in the X direction. In particular, the electrode groups 32b and 32c are arranged apart from each other in the X direction.

  The electrode group 32b includes a plurality of (for example, three each) divided electrodes 32d, 32e, and 32f arranged at equal intervals in the Y direction. The electrode group 32c includes a plurality of (for example, three each) divided electrodes 32g, 32h, and 32j arranged at equal intervals in the Y direction. As an example, each divided electrode of the front electrode portion 32 of this example has a dimension X5 in the X direction larger than a dimension Y6 in the Y direction, and the dimension Y6 is larger than the distance Y7 between the divided electrodes. As an example, each electrode of the front electrode portion 32 has a shape that can be regarded as a substantially rectangular shape. When the muscular electrical stimulation device 10 is attached to the abdominal part 3, the pair of electrode groups 32 b and 32 c are arranged in a region corresponding to the rectus abdominis muscle 4 and cause a current in the circumferential direction to flow through the rectus abdominis muscle 4. In this example, each divided electrode of the pair of electrode groups 32 b and 32 c is arranged corresponding to a section divided by each tendon of the rectus abdominis muscle 4.

  As an example, the front electrode portion 32 is disposed symmetrically with respect to the control unit 30 in the X direction and the Y direction. In particular, the front electrode portion 32 is line symmetric with respect to the bisector M1. In particular, the front electrode portion 32 of this example is line symmetric with respect to a bisector M2 that bisects the arrangement region 32a of the front electrode portion 32 in the Y direction.

  When the muscular electrical stimulation device 10 is used while being attached to the abdomen 3, a gel pad 82 (see FIG. 5) is disposed between the front electrode part 32 and the abdomen 3. The gel pad 82 has adhesiveness. The gel pad 82 plays a role of ensuring conduction between the body and each electrode by the adhesive force. The gel pad 82 is affixed to each electrode part of the muscular electrical stimulation apparatus 10. The muscle electrical stimulation device 10 is attached to the abdomen 3 with the gel pad 82 attached. The muscle electrical stimulation device 10 is supported by the abdomen 3 due to the adhesiveness of the gel pad 82.

  One gel pad 82 may be attached to each divided electrode of the front electrode part 32. In this example, the gel pad 82 has a shape that collectively covers a plurality of divided electrodes, as shown in FIG. That is, the gel pad 82 is configured to be attached one by one for each of the electrode groups 32b and 32c. In this case, it is possible to reduce the trouble of attaching the gel pad 82 as compared with the case where one is provided for each divided electrode.

(Side electrode part)
As shown in FIG. 7, the side electrode part 36 is arranged in an arrangement region 36 a having a dimension X7 in the X direction and a dimension Y5 in the Y direction. The side electrode part 36 may include a plurality of electrodes that are spaced apart by a distance X9 in the X direction. The distance X9 may be set corresponding to the width of the oblique oblique muscle 5. The side electrode portion 36 of this example includes first electrodes 36b and 36d and second electrodes 36c and 36e that are spaced apart in the X direction. In particular, the first electrodes 36 b and 36 d and the second electrodes 36 c and 36 e are arranged apart from each other in the X direction corresponding to the circumferential direction of the abdomen 3. The first electrodes 36b and 36d and the second electrodes 36c and 36e are collectively referred to as side electrodes. The first electrode 36b and the second electrode 36c are disposed on one extending portion 26 with a distance X9 therebetween in the X direction. When the muscular electrical stimulation device 10 is attached to the abdomen 3, the first electrode 36b and the second electrode 36c are arranged in the X direction corresponding to the abdominal oblique muscle 5 in the circumferential direction, and correspond to the abdominal oblique muscle 5 in the circumferential direction. A current in the X direction is applied.

  The first electrode 36d and the second electrode 36e are spaced apart from each other in the X direction and are disposed on the other extending portion 26. When the muscular electrical stimulation device 10 is attached to the abdomen 3, the first electrode 36d and the second electrode 36e are arranged in the X direction corresponding to the abdominal oblique muscle 5 in the circumferential direction, and correspond to the abdominal oblique muscle 5 in the circumferential direction. A current in the X direction is applied. As an example, each side electrode of the side electrode portion 36 of this example has a dimension Y5 in the Y direction larger than a dimension X8 in the X direction. As an example, each side electrode of the side electrode portion 36 has a shape that can be regarded as a substantially rectangular shape.

  As an example, the side electrode part 36 is disposed symmetrically with respect to the control unit 30 in the X direction and the Y direction. In particular, the side electrode part 36 is line symmetric with respect to the bisector M1. In particular, the side electrode portion 36 of this example is line symmetric with respect to the bisector M2.

  When the muscular electrical stimulation device 10 is attached to the abdomen 3, a gel pad 82 is disposed between the side electrode part 36 and the abdomen 3. As an example, as shown in FIG. 5, a gel pad 82 having a shape covering each side electrode is attached to each side electrode and used.

(Extension part)
The pair of extending portions 26 are attached at positions corresponding to the oblique oblique muscles 5 on the side surface of the abdominal portion 3. Each extending portion 26 is provided with a side electrode portion 36 that allows current to flow through the oblique oblique muscle 5. The extending part 26 extends in the X direction and the Y direction and is formed thin in the Z direction. The extension part 26 has a shape that can be regarded as a substantially rectangular shape in which the longitudinal direction is arranged along the X direction in a front view.

  As an example, the dimension Y2 in the Y direction of the extending part 26 of this example is smaller than the dimension Y1 in the Y direction of the front part 22. As an example, the extending portion 26 of this example has a shape that can be regarded as a substantially rectangular shape, and the dimension X4 in the X direction is larger than the dimension Y2 in the Y direction. As an example, the dimension Y2 in the Y direction of the pair of extending portions 26 of this example is smaller than the dimension Y3 in the Y direction of the arrangement region 32a of the front electrode part. One extending portion 26 is provided with a side electrode portion 36 having a first electrode 36b and a second electrode 36c that are spaced apart in the X direction. As an example, the dimension Y2 in the Y direction of the pair of extending portions 26 of this example is smaller than the distance X9 in the X direction between the first electrode 36b and the second electrode 36c. In the example of FIG. 7, the dimensions and distances in the Y direction have a relationship of distance Y7 <dimension Y6 <dimension Y4 <dimension Y5 <dimension Y2 <dimension Y1. In the example of FIG. 7, each dimension and distance in the X direction has a relationship of dimension X8 <dimension X5 <distance X6 <distance X9 <dimension X7 <dimension X3 <dimension X4 <dimension X2.

  Since the abdominal circumference varies from person to person, the distance from the front of the abdomen 3 to the oblique oblique muscle 5 is considered to vary greatly from person to person. For this reason, if the distance X9, which is the separation distance between the first electrode 36b and the second electrode 36c, is too small, the range in which the current flows through the oblique oblique muscles 5 may be narrowed. Therefore, in this example, the distance X9 between the first electrode 36b and the second electrode 36c is set larger than the distance X6 between the electrode group 32b and the electrode group 32c. In this case, the range through which the current of the oblique oblique muscle 5 flows is wider than when the distance X9 is smaller than the distance X6.

  Since the abdominal circumference varies from person to person, the range in the direction orthogonal to the stretching direction of the muscle is considered to vary greatly from person to person. For this reason, each electrode of the muscular electrical stimulation device 10 is arranged so that a current in the circumferential direction flows through the rectus abdominis muscle 4 and the oblique abdominal muscle 5. That is, each electrode can pass a current in a direction substantially perpendicular to the stretching direction of these muscles. In this case, it is expected that stimulation is applied to a wide range of muscles as compared with the case where an electric current is passed in the stretching direction of the muscles.

  Moreover, since each electrode is spaced apart and arrange | positioned in the direction substantially orthogonal to the twist direction of the extension part 26, compared with the case where it arrange | positions in a twist direction, an electrode can be made to contact a body stably.

  The direction of the current flowing through the rectus abdominis muscle 4 and the direction of the current flowing through the abdominal oblique muscle 5 can be set by the polarity of the voltage applied to the front electrode portion 32 and the side electrode portion 36. The direction of the current flowing through the rectus abdominis muscle 4 may be the same direction as the current flowing through the abdominal oblique muscle 5 or may be the opposite direction. In this example, the polarity of the voltage applied to the front electrode portion 32 and the side electrode portion 36 is set so that the current flowing through the rectus abdominis 4 flows in the opposite direction to the current flowing through the abdominal oblique muscle 5. .

(Control part)
Next, the control unit 30 will be described. Each block of the control unit 30 shown in FIG. 2 and control units 70 and 130 to be described later can be realized in terms of hardware by elements and mechanical devices such as a CPU (Central Processing Unit) of a computer. Is realized by a computer program or the like, but here, functional blocks realized by their cooperation are depicted. Therefore, it is understood by those skilled in the art who have touched this specification that these functional blocks can be realized in various forms by a combination of hardware and software.

  The control unit 30 includes a control unit 30a, a switch unit 20j, 20k, a charging terminal 20g, and a battery 20h housed in a housing 30m. The housing 30 m is provided in the center of the main body 20 and forms an outer shell of the control unit 30. The housing 30m can be formed of various resin materials. The switch units 20j and 20k are provided in front of the control unit 30. The switch unit may be referred to as an SW unit. The switch units 20j and 20k detect that the pressing operation has been performed, and output the detection result to the control unit 30a. The switch units 20j and 20k may include, for example, an electrical contact that is closed when not operated and changes to open when pressed. A plus sign is displayed on the surface of the switch unit 20j of the present example, and a minus sign is displayed on the surface of the switch unit 20k of the present example.

  The battery 20h is electrically connected to the control unit 30a and supplies power to the control unit 30a. The battery 20h may be a primary battery, but in this example, a lithium ion battery that can be repeatedly charged is employed. The battery 20h may be replaceable, but in this example, a built-in type is adopted. The charging terminal 20g receives power for charging the battery 20h and outputs it to the control unit 30a. Various connectors can be used for the charging terminal 20g. In this example, a USB (registered trademark) standard connector is used. The charging terminal 20g is provided on the bottom surface of the control unit 30, for example. The battery 20h is charged with the power received at the charging terminal 20g. The battery 20h may be configured to be charged by a contactless charging system such as wireless charging.

  The control unit 30a includes a communication unit 30b, a skin detection unit 30c, an operation acquisition unit 30d, an electrical stimulation control unit 30e, a charge control unit 30g, and a mode control unit 30f. The communication unit 30 b can transmit the operation status of the electrical muscular stimulation device 10 to the remote control device 12. The remote control device 12 displays the operation status acquired from the communication unit 30b. The communication unit 30b receives operation information based on the touch operation input to the remote control device 12. The control unit 30a controls the operation of the electrical muscular stimulation device 10 according to operation information acquired via the communication unit 30b.

  The operation acquisition unit 30d acquires operation detection results from the switch units 20j and 20k. The operation acquisition unit 30d detects a voltage corresponding to the resistance value of each switch unit, determines that the switch unit has been pressed when the detected voltage is equal to or higher than the threshold value, and switches when the detected voltage is lower than the threshold value. Is determined not to be operated. The control unit 30a determines the control method of the electrical muscular stimulation device 10 according to the combination of the pressing state of each switch unit, the length of the pressing time, and the like.

  When the operation by the remote control device 12 is being performed, the operation of the switch units 20j and 20k may be prohibited. The electrical muscular stimulation device 10 of this example allows operation by the switch units 20j and 20k even when the remote control device 12 is operating. In this case, even when the remote control device 12 cannot be operated because the user is away from the remote control device 12, the electrical muscular stimulation device 10 can be operated by the switch units 20j and 20k.

  The skin detection unit 30c detects whether the electrode is in contact with the skin. The skin detection unit 30c detects the resistance value between the electrode group 32b and the electrode group 32c, determines that the electrode is in contact with the skin when the detected resistance value is less than the threshold value, and the detected resistance value is the threshold value. In the above case, it is determined that the electrode is not in contact with the skin.

  When the skin detection unit 30c detects that the electrode is in contact with the skin, the electrical stimulation control unit 30e has a predetermined operation time (for example, 20 minutes) and a power corresponding to the set output voltage at a predetermined cycle. Is supplied to the electrode. That is, electrical stimulation is given to the user's abdomen 3 during this operation time. The output voltage can be changed by operating the remote control device 12 or the switch units 20j and 20k. In the electrical stimulation control unit 30e of this example, the output voltage increases every time the switch unit 20j is pressed, and the output voltage decreases every time the switch unit 20k is pressed.

  The charging control unit 30g controls the charging power received at the charging terminal 20g and supplies it to the battery 20h. The charging control unit 30g controls the magnitude of the current supplied to the battery 20h according to the charging rate of the battery 20h. For example, when the charging rate is low, the current supplied to the battery 20h is increased, and when the charging rate is high, the current supplied to the battery 20h is decreased. When the increase rate of the charging rate with respect to the charged amount of charge is small, the charging control unit 30g stops charging as a battery failure.

(Mode control unit)
The control unit 30 can control the first voltage V <b> 1 supplied to the front electrode part 32 and the second voltage V <b> 2 supplied to the pair of side electrode parts 36. The control unit 30 has an independent control mode for independently controlling the first voltage V1 and the second voltage V2, and a simultaneous control mode for simultaneously controlling the first voltage V1 and the second voltage V2.

  In the independent control mode, when one of the stimulations of the rectus abdominis 4 and the abdominal oblique muscle 5 is to be adjusted, one of the first voltage V1 and the second voltage V2 can be selected and controlled. For example, in the independent control mode, one of the first voltage V1 and the second voltage V2 can be fixed and the other can be increased or decreased. In the independent control mode, one of the first voltage V1 and the second voltage V2 can be increased or decreased while fixing one to zero.

  In the simultaneous control mode, when it is desired to adjust the stimulation of the rectus abdominis muscle 4 and the stimulation of the oblique abdominal muscle 5 in conjunction with each other, the first voltage V1 and the second voltage V2 can be controlled in conjunction with each other. For example, in the simultaneous control mode, the first voltage V1 and the second voltage V2 can be increased or decreased simultaneously. In the simultaneous control mode, the first voltage V1 and the second voltage V2 can be increased or decreased simultaneously in the same voltage state. In the simultaneous control mode, the first voltage V1 and the second voltage V2 can be increased or decreased simultaneously in a state where there is a voltage difference.

  The mode control unit 30f performs control to switch between the independent control mode and the simultaneous control mode. The electrical stimulation control unit 30e can switch between the independent control mode and the simultaneous control mode by operating the remote control device 12 or the switch units 20j and 20k. When switched to the simultaneous control mode, the first voltage V1 and the second voltage V2 are adjusted in an interlocking manner. When switching to the independent control mode, one of the first voltage V1 and the second voltage V2 is fixed, and only the other is adjusted.

(Belt connecting part)
The main body portion 20 may be provided with a pair of connecting portions that are arranged apart from each other in the X direction and connect an attracting member for pulling the main body portion 20 toward the abdomen 3 that is the attached portion. . In particular, the pair of connecting portions may be provided on the pair of extending portions 26. In this example, a pair of belt connecting portions 42 that connect the belt member 50 for pulling the main body portion 20 toward the abdominal portion 3 side around the abdominal portion 3 is provided. The belt connecting portion 42 is not particularly limited as long as the belt member 50 can be connected. The belt connecting portion 42 of this example includes a rectangular tubular member 42k that surrounds a hole 42h through which the belt member 50 passes. The square tube member 42k has a substantially rectangular shape whose longitudinal direction extends in the Y direction when viewed from the front, and is provided with a substantially rectangular hole portion 42h that is long in the Y direction at the center. The belt connecting part 42 may be formed of a resin material, for example. The pair of square tube members 42k are fitted into and attached to attachment holes 26h formed at the end of the extension portion 26 on the side far from the front portion 22 in the X direction. By using the square tube member 42k, the force received from the belt member 50 is received by the square tube member 42k. Therefore, compared to the case where the square tube member 42k is not used, the first base material 14, the second base material 15, and the cover member. The load applied to 16 is dispersed, and the occurrence of tearing of the belt member 50 and deformation of the appearance can be suppressed. Moreover, the shift | offset | difference of the layer structure of the 1st base material 14, the 2nd base material 15, and the cover member 16 can also be suppressed.

(Belt member)
The belt member is an attracting member that extends in the X direction on the opposite side of the mounted portion from the main body portion 20 and is bridged between a pair of connecting portions. The drawing member is not particularly limited as long as the drawing member has a property that allows it to pass through the opposite side of the mounted portion and be connected to the connecting portion of the main body portion 20. As an example, a strip-shaped member made of various materials, a string-shaped member, a wire-shaped member, or the like can be adopted as the attracting member. The belt member 50 of this example is a cloth-like belt-like member.

  Hereinafter, the example of FIG. 8 will be described as an example. FIG. 8 is a plan view showing an example of the belt member 50 connected to the electrical muscular stimulation device 10. In FIG. 8, the main body portion 20 is extended in the X direction for easy understanding, and the abdomen 3 is displayed smaller than the actual ratio. FIG. 9 is a side view showing a state in which the electrical muscular stimulation device 10 is attached to the abdomen 3.

  The belt member 50 includes a band-shaped first member 50b and a second member 50c. The second member 50c is connected to the hole 42h of the square tube member 42k provided in the connecting portion 42c which is the other of the pair of belt connecting portions 42. A portion 50j close to one end 50g of the first member 50b is connected to a hole 42h of a square tube member 42k provided in a connecting portion 42b which is one of a pair of connecting portions.

  A folded portion 50e is formed in the middle of the first member 50b. The folded portion 50e is configured to be switchable between a state connected to the second member 50c and a state disconnected from the second member 50c. That is, the folding | returning part 50e is comprised so that attachment or detachment with respect to the 2nd member 50c is possible. FIG. 9A shows a state in which the folded portion 50e is separated from the second member 50c. FIG. 9B shows a state in which the folded portion 50e is connected to the second member 50c. The second member 50c and the first member 50b are provided with a surface fastener portion that is detachable in terms of surface, and can be folded back at a desired position and maintained.

  If the length of the first member 50b in the longitudinal direction is too short, it is difficult to use for a user with a large abdominal circumference. If the length of the first member 50b in the longitudinal direction is too long, when used for a user with a small abdominal girth, the portion from the folded portion 50e becomes too long and hangs down and becomes complicated. Therefore, the dimension in the longitudinal direction of the first member 50b in the unfolded state may be set in a range from n times (n is an integer of 2 or more) to n + 1 times the dimension X1 in the X direction of the main body portion 20. In this example, the dimension in the longitudinal direction of the first member 50b in the unfolded state is set in the range of two to three times the dimension X1 of the main body 20 in the X direction. In this range, it can be used by a user with a large abdominal girth and a user with a small abdominal girth.

  It is conceivable that the edge of the layer material such as the cover member 16 is exposed in the mounting hole 26h of the main body portion 20, and becomes a resistance when passing through the first member 50b and the second member 50c, so that the work cannot be performed smoothly. Therefore, the mounting hole 26h is provided with a square tube member 42k that is an encircling member surrounding the second member 50c or the first member 50b. Since the square tube member 42k covers the edge of the layer material, the first member 50b and the second member 50c can be smoothly passed. The square tube member 42k may be fitted into the attachment hole 26h and fixed by adhesion or the like.

  The example of FIG. 8 will be described in more detail. The second member 50c is folded back through the hole 42h of the square tube member 42k of the connecting portion 42c, and both end portions of the second member 50c are connected by the hook-and-loop fastener 51b. The second member 50c may be formed shorter than the first member 50b.

  One end 50g of the first member 50b is folded in a state of passing through the hole 42h of the square tube member 42k of the connecting portion 42b, and is connected to the intermediate portion 50m of the first member 50b by the surface fastener 51c. . The other end portion 50h of the first member 50b is folded to adjust the length to form a folded portion 50e, and is connected to another intermediate portion 50k of the first member 50b by a surface fastener 51d. As shown in FIG. 8, an intermediate part 50n slightly separated from the end part 50h may be connected to the intermediate part 50k.

  The folded portion 50e can be connected to the second member 50c by a hook-and-loop fastener 51e. The electrical muscular stimulation device 10 is worn along the periphery of the user's abdomen 3 with the folded portion 50e away from the second member 50c. The electrical muscular stimulation device 10 is attached to the abdomen 3 by connecting the folded portion 50e to the second member 50c while being attached along the periphery of the abdomen 3. By changing the folding position of the folding portion 50e, the circumferential length of the first member 50b can be easily adjusted.

A method of using the electrical muscular stimulation device 10 configured as described above on a worn part of the body will be described. This method includes the following steps.
(1) One end 50g side portion of the first member 50b is connected to the hole 42h of the square tube member 42k provided in the connecting portion 42b.
(2) The 2nd member 50c is connected with the hole 42h of the square tube member 42k provided in the connection part 42c.
(3) The folded portion 50e is formed on the other end 50h side of the first member 50b.
(4) The main body 20 is disposed on the mounted portion.
(5) The folded portion 50e is connected to the second member 50c through the opposite side of the mounted portion from the main body portion 20.
About the muscular electrical stimulation apparatus 10 mounted | worn in this way, the switch part 20j, 20k or the remote control apparatus 12 can be operated, and the muscular electrical stimulation apparatus 10 can be operated.
Other steps may be added to this step, or the order of the steps may be changed.

  The operation of the electrical muscular stimulation device 10 configured as described above will be described. FIG. 10 is a flowchart showing an example of the operation of the muscular electrical stimulation device 10. FIG. 10 shows a process S100 from when the user turns on the power in a state where the muscular electrical stimulation device 10 is attached to the abdomen 3, and from when the electrical stimulation to the abdomen 3 is started to when it is finished.

  When the process is started, the control unit 30a determines whether or not the switch unit 20j is pushed down (step S102). When the switch unit 20j is not pressed down (N in Step S102), the control unit 30a returns the process to the beginning of Step S102 and repeatedly executes Step S102. When the switch unit 20j is pushed down (Y in step S102), the control unit 30a determines whether or not a predetermined elapsed time T1 has elapsed (step S104).

  When the elapsed time T1 has not elapsed (N in Step S104), the control unit 30a returns the process to the beginning of Step S102, and repeatedly executes Steps S102 to S104. When the elapsed time T1 has elapsed (Y in step S104), the control unit 30a proceeds to step S106. The elapsed time T1 in step S104 can be set according to desired specifications. The elapsed time T1 in this example is set to 2 seconds. That is, the user can turn on the electric power of the muscular electrical stimulation device 10 by pressing the switch unit 20j for 2 seconds.

  In step S106, the control unit 30a determines whether or not the electrode is in contact with the skin (step S106). When the electrode is not in contact with the skin (N in Step S106), the control unit 30a waits for a predetermined waiting time and then returns the process to the beginning of Step S106.

  When the electrode is in contact with the skin (Y in step S106), the control unit 30a starts applying electrical stimulation to the user's abdomen 3 (step S108). In this step, the electrical stimulation control unit 30e supplies power changing at a predetermined cycle to at least one of the front electrode unit 32 and the side electrode unit 36.

  The control unit 30a that has executed Step S108 determines whether or not a predetermined elapsed time T2 has elapsed (Step S110). The elapsed time T2 in step S110 can be set according to a desired training time. The elapsed time T2 in this example is set to 20 minutes. That is, the user can continue training until 20 minutes have passed. When the elapsed time T2 has not elapsed (N in Step S110), the control unit 30a determines whether or not the electrode is in contact with the skin (Step S112).

  When the electrode is in contact with the skin (Y in Step S112), the control unit 30a returns the process to the beginning of Step S108 and continues to apply the electrical stimulus. When the electrode is not in contact with the skin (N in step S112), the control unit 30a stops applying electrical stimulation and ends the process S100. That is, even when the elapsed time T2 has not elapsed, when the electrode is separated from the body 2, the control unit 30a ends the application of electrical stimulation. When the elapsed time T2 has elapsed (Y in step S110), the control unit 30a stops applying electrical stimulation and ends the process S100.

  The process S100 is merely an example, and other processes may be added to the process, steps may be deleted / changed, or the order of the steps may be changed.

  The operation and effect of the electrical muscular stimulation device 10 according to the first embodiment configured as described above will be described.

  The electrical muscular stimulation device 10 according to the first embodiment includes a main body portion 20 having a mounting surface 10b that is mounted along the periphery of a body mounted portion, and the mounting surface 10b goes around the mounted portion in the X direction. The front electrode part 32 is arranged in the main body part 20 so as to be spaced apart from each other and allows a current to flow through the attached part, and is arranged apart in the X direction so that the main body part 20 is placed on the attached part side.

The electrical muscular stimulation device 110 has a mounting surface 10b that is mounted along the circumference of the upper thigh 6a when mounted. In a state where the mounting surface 10b is developed along a plane, the mounting surface 10b extends in the X direction and the Y direction orthogonal to the X direction. Although not shown in FIG. 11, the direction orthogonal to the X direction and the Y direction is defined as the Z direction. The Z direction is orthogonal to the mounting surface 10b.

  In the example of FIG. 11, in the electrical muscular stimulation device 110, the Y direction of the mounting surface 10 b is along the extending direction (vertical direction) of the lower limb 6, and the X direction of the mounting surface 10 b is along the direction of circling the upper leg 6 a. It is attached to. Hereinafter, the Y direction may be referred to as an upward direction or a downward direction, and the Z direction may be referred to as a thickness direction. Such notation of the direction does not limit the posture of use of the electrical muscular stimulation device 110, and the electrical muscular stimulation device 110 can be used in an arbitrary posture.

  The muscular electrical stimulation device 110 includes a main body 120 and two belt members 50 provided to be separated in the Y direction. The main body 120 is wound around the front side or the back side of the upper leg 6a along the circumferential direction. The belt member 50 is connected to the other end of the main body 120 from one end of the main body 120 around the back side or front side of the upper thigh 6a in the circumferential direction. The belt member 50 is the same as that in the first embodiment.

  The main body 120 is provided with a control unit 130, a belt coupling portion 42, and a pair of electrodes 132 that are spaced apart in the Y direction. The control unit 130 is an electronic unit that supplies a voltage for muscle stimulation to the pair of electrodes 132. The belt connecting portion 42 is a member that connects the two belt members 50 to the main body portion 120. The pair of electrodes 132 are sheet-like electrodes that supply a muscle stimulation voltage to the body. The pair of electrodes 132 includes a first electrode 132b and a second electrode 132c that are spaced apart in the Y direction. In this example, the first electrode 132b and the second electrode 132c are provided such that the longitudinal direction thereof is parallel to the X direction.

  The main body 120 is formed in a substantially rectangular shape as a whole by arranging two strips 120b and 120c extending in the X direction in the Y direction. The main body 120 may be formed in a substantially square shape. The two strips 120b and 120c may be partially connected and the remaining portions may be separated. A pair of belt connecting portions 42 may be provided at both ends in the X direction of the two strips 120b and 120c.

  The control unit 130 may be provided closer to one end side in the X direction at the center position in the Y direction of the main body 120. The control unit 130 may be arranged such that its center is located on a straight line M3 that bisects the main body 120 in the Y direction and extends in the X direction. The control unit 130 may be provided in an overhanging portion 120e that projects from the end of the main body 120 in the X direction. The main body 120 may be formed symmetrically with respect to the control unit 130 by including two strips 120b and 120c. In particular, the main body 120 may be formed symmetrically with respect to the straight line M3. The pair of electrodes 132 may be disposed symmetrically with respect to the control unit 130. In particular, the pair of electrodes 132 may be arranged symmetrically with respect to the straight line M3.

  In this example, the main body 120 is attached to the upper thigh 6a. The pair of electrodes 132 is configured to flow a current for muscle stimulation along the Y direction to the muscle 7b of the upper leg 6a. That is, the pair of electrodes 132 are arranged so that a current flows through the muscle 7b of the upper thigh 6a along the extending direction of the muscle fibers.

  FIG. 13 is a front view of the muscular electrical stimulation device 110. FIG. 14 is a plan view of the electrical muscular stimulation device 110. FIG. 15 is a rear view of the muscular electrical stimulation device 110. FIG. 16 is a rear view showing an example of the arrangement of the lead portion 37 of the muscular electrical stimulation device 110. FIGS. 13-16 has shown the state which expand | deployed the muscular electrical stimulation apparatus 110 and made the mounting surface 10b follow the vertical surface. As shown in FIGS. 13 to 16, in the unfolded state, the X direction corresponding to the circumferential direction of the lower limb 6 and the Y direction corresponding to the vertical direction of the lower limb 6 are linearly indicated by arrows X and Y. .

(Main body)
The main body 120 may have a layer structure. The layer structure is the same as in the first embodiment. The main body 120 is mounted along the circumferential direction at a position corresponding to the muscle 7b of the upper leg 6a of the lower limb 6, for example. The main body 120 extends in the X direction and the Y direction and is formed thin in the Z direction. The main body 120 is provided with a pair of electrodes 132 that are spaced apart from each other in the Y direction. As described above, the pair of electrodes 132 is configured to cause a current to flow through the muscle 7b of the upper leg 6a in a direction orthogonal to the circumferential direction. The main body 120 has a shape that can be regarded as a substantially rectangular shape in which the longitudinal direction is arranged along the X direction in a front view. The vent hole 23g is the same as in the first embodiment.

  In many cases, the peripheral surface of the upper leg 6a has a shape like a conical surface whose radius of curvature increases toward the base side. For this reason, when the main body 120 that does not include the branch portion is attached to the upper thigh 6a, the main body 120 is attached to the upper thigh 6a with a heel portion formed in part. In a state where the heel portion is formed, it is conceivable that the pair of electrodes 132 is inclined with respect to the peripheral surface of the upper leg portion 6a, and a part of the electrodes 132 is floated to make the contact unstable. For this reason, a part in the X direction of the main body 120 may be branched into a plurality in the Y direction so as to correspond to different radii of curvature. As an example, the main body 120 has a bifurcated shape in which a part in the X direction is separated in the Y direction by a gap 124g. That is, the main body 120 includes two strips 120b and 120c separated by the gap 124g.

  The strip 120b has an edge 120m in contact with the gap 124g. The strip 120c has an edge 120n in contact with the gap 124g. That is, the gap 124g is a region sandwiched in the Y direction by the edge portions 120m and 120n. The strips 120b and 120c are partially connected and the remaining portions are separated. The strips 120b and 120c of this example are each formed in a strip shape in which the dimension in the X direction is larger than the dimension in the Y direction. The gap 124g is formed from the end 120a in the X direction of the main body 120 toward the inside in the X direction.

  The main body 120 of this example is formed symmetrically with respect to a straight line that passes through the center of the gap 124g in the Y direction and extends in the X direction. In this example, the pair of electrodes 132 is provided in each region separated by a gap 124 g of the main body 120. Since the strips 120b and 120c separated by the gap 124g of the main body 120 are independently wound around the upper thigh 6a, wrinkles are less likely to occur and the contact with the body can be stabilized. Since it has a bifurcated shape, even when the thickness changes like the upper thigh 6a, the bifurcated belt-like bodies 120b and 120c are individually curved, so that the generation of wrinkles can be reduced. The dimension in the Y direction of the gap 124g, which is a bifurcated cut depth, may be deep when the upper leg of the lower limb is to be worn, and shallow when the upper limb is to be worn.

  In the case of having a bifurcated shape separated by the gap 124g, stress concentrates on the portion of the main body 120 that contacts the innermost portion of the gap 124g, and there is a risk that defects such as cracks may occur in that portion. Therefore, in the present example, a thick portion 124h formed in a thickness is provided at a portion of the main body 120 that contacts the gap 124g. In particular, the thick portion 124h may be provided around a portion in contact with the innermost portion of the gap 124g of the main body portion 120. The shape of the thick portion 124h can be set by simulation according to desired durability.

(A pair of electrodes)
As described above, the pair of electrodes 132 includes the first electrode 132b and the second electrode 132c that are spaced apart in the Y direction. The longitudinal direction of each of the pair of electrodes 132 is arranged in parallel to the X direction. Each of the pair of electrodes 132 is formed in a substantially rectangular shape. Each of the pair of electrodes 132 is arranged in the X direction, which is the circumferential direction of the upper thigh 6a, and a current in the Y direction flows through the muscle 7b of the upper thigh 6a. The pair of electrodes 132 is provided on the second base material 15, and is exposed to the mounting surface 10 b from the opening 14 b provided in the first base material 14. The first electrode 132b is electrically connected to the terminal 38m by the wiring 37m, and the second electrode 132c is electrically connected to the terminal 38n by the wiring 37n.

The pair of belt connecting portions 42 is provided in each of the two belt-like bodies 120b and 120c so as to be separated from each other in the X direction (see also FIG. 15). In a state where the main body 120 is wound in the X direction, the pair of belt connecting portions 42 are arranged in the X direction. The belt connecting portion 42 and the belt member 50 are the same as in the first embodiment.
