Description

  The present invention relates to a pressurization device that attaches a long belt to a pressurization target such as an arm or a leg, tightens the pressurization target, pressurizes, and restricts blood flow.

  It is known that when a belt wearer exercises while wrapping a belt around the arm or leg base of a human body and restricting blood flow, a good effect on health such as promoting enhancement of muscle strength is exhibited.

  Such pressurization devices for strength training, treatment, and rehabilitation are roughly classified into two types. One of them is an analog pressure device that increases the size of the belt that is wound around the base of the hand or leg and pressurizes according to the tightening strength. The other is a digital pressurizing device provided with a pump for sending air to the inflatable air bag and a control device for automatically adjusting the pressure of the air bag in addition to the air bag and sensor provided on the belt.

  An analog instrument is disclosed in Patent Document 1 (Japanese Patent No. 2670421). This pressurizing device has a long belt main body, an annular member attached to one end of the belt main body, and the other end of the belt main body is passed through the opening of the annular member to form a ring around the arm. A fastener member that maintains the form of the belt body.

  The degree of pressure applied to the arm depends on whether the belt body is tightened on the arm, so a rubber air bag configured separately from the belt body, a manual pump member that sends air to the air bag, and an air A measuring instrument for measuring the pressure in the bag is prepared, and the pressure is checked in advance using these measuring instruments.

  For example, an air bag connected to a pump member and a measuring instrument via a connecting tube is attached to the belt body. Next, the belt main body is put on the arm together with the air bag, and the movement of the belt main body is restricted by the fastener member, and the belt main body is attached. Air is sent to the air bag by the pump member, and it is confirmed whether a predetermined pressure is reached. When the desired pressure is reached, the position of the belt fixed by the fastener member, for example, the position of the belt front end is marked to reproduce the winding condition of the belt body.

  At the time of actual training, the air bag is removed from the belt body, and the belt body is again attached to the pressurizing object with the tip of the belt aligned with the mark. The mounting of such a pressure device generally requires adjustment of pressure adjustment with the assistance of a person familiar with the use of the pressure device. To make adjustments by the wearer himself, it is necessary to learn how to use it from the instructor.

  Patent Document 2 (Japanese Patent No. 2796276) discloses a pressurizing device in which an air bag is integrally provided on a belt body. This pressurizing device does not require the work of removing the air bag from the belt body, but it is necessary to adjust the pressure by the pump member with the assistance of a person familiar with the use of the pressurizing device.

  Digital instruments are disclosed in Patent Documents 3 and 4. The pressurizing device disclosed in Patent Document 3 (Japanese Patent No. 2796277) includes an air bag and a sensor for measuring the pressure of the air bag on the belt body. Patent Document 4 (Japanese Patent No. 4322591) discloses a muscular strength enhancing system. The system includes a pressure device and a device that controls the pressure on the pressure device.

Japanese Patent No. 2670421 Japanese Patent No. 2796276 Japanese Patent No. 2796277 Japanese Patent No. 4322591

The zigzag stitches change direction at a predetermined interval in the length direction of the belt main body, and a mountain portion (a portion surrounded by a circle 121A in FIG. 1) and a valley portion (FIG. 1). And a portion surrounded by a circle denoted by reference numeral 121 </ b> B) are arranged close to the edge in the width direction of the core material 110. The first stretch material 120 covered with the second stretch material 130 in FIG. 1 is also stitched to the core material 110 with zigzag stitches.

  The second stretch material 130 is also made of a stretchable fabric like the first stretch material 120, but uses a material shorter than the first stretch material 120.

  The first stretch material 120 and the second stretch material 130 are stitched to the core material 110 to form a belt-shaped belt body 100. Details of the configuration of the belt main body 100 will be described below.

  The belt body 100 is roughly divided into two regions. One area is from a position near one end where the annular member 200 is attached to a predetermined position, and this area is configured to accommodate an air bag 400 described later. In the remaining region on the other end side from this region, the air bag 400 cannot be accommodated inside. A portion of the belt main body 100 in which the air bag 400 is accommodated is hereinafter referred to as an accommodation portion (FIG. 1).

  The length of the accommodating portion is selected so that it occupies at least two-thirds around the arm or leg to be pressurized. The length of the belt main body 100 is set so that the portion on the other end side from the accommodating portion is slightly shorter than the entire length of the accommodating portion.

  A second stretch material 130 is provided in the region of the accommodating portion of the belt main body 100. The second stretch material 130 is stitched to the core material 110 and the first stretch material 120 at the periphery thereof, and the air bag 400 can be accommodated between the first stretch material 120 and the first stretch material 120 as shown in FIG.

In the air bag 400 of the present embodiment, the dimension L of the air bag 400 is selected so as to occupy two-thirds of the circumference around the arm or leg as a pressurization target . The air bag 400 is arranged with the length direction along the length direction of the pressure belt 10 in the accommodating portion. It is desirable that the air bag 400 is disposed without gaps in the accommodating portion.

  The length of the air bag 400 is not limited to the above configuration example, but if the air bag 400 is made longer than the length of the circuit around the pressurization object, a part of the air bag does not act on the arms or legs. The length of the object to be pressurized is shorter than the length of the circuit.

  FIG. 5 is a view for explaining the configuration of the air bag 400. The air bag 400 is formed by stacking two sheet-like urethane sheets 411 and 412. Each of the urethane sheets 411 and 412 is formed into an elongated rectangular shape with a short side V1 and a long side V2. The short side V1 is about the width of the belt body 100, and the long side V2 is more than two-thirds of the length around the arms and legs. An air bag 400 is configured by welding the peripheral edges of these urethane sheets 411 and 412 by ultrasonic waves except for an insertion portion of a tube 415 described later.

  The air bag 400 includes a tube 415 protruding from the edge of one long side V2. The tube 415 is sandwiched between the urethane sheets 411 and 412 and joined to the urethane sheets 411 and 412 when the urethane sheets 411 and 412 are joined. Hereinafter, this tube is called an entrance / exit part.

  As shown in FIG. 3, the air bag 400 has a wide surface of one urethane sheet 411 applied to the first stretch material 120, a wide surface of the other urethane sheet 412 applied to the second stretch material 130, and an entrance / exit portion 415 is provided. It is arranged in the accommodating portion in a posture arranged on the lower side. The entrance / exit part 415 is arranged so as to appear from the inside of the belt main body 100 to the outside as shown in FIGS. 1 and 3.

  Furthermore, in this embodiment, as shown in FIG. 3, the elastic member 500 is provided in the air bag. As shown in FIG. 3, the elastic member 500 is disposed in an internal space S that is an area formed by two urethane sheets 411 and 412. When forming the air bag 400, the stretchable member 500 is put between the two urethane sheets 411 and 412 as shown by the one-dot chain arrows in FIG. The length of the elastic member 500 is selected so that the air bag 400 swells over the entire length of the air bag 400 in the air bag 400. The elastic member 500 may be formed, for example, in the same length as the air bag 400 or may be formed shorter than the air bag 400 with a thickness.

  The elastic member 500 is a highly repulsive urethane and is configured as an open-cell sponge sheet. Also, a resin molded product having elasticity may be used as the elastic member 500.

  The sheet-like stretchable member 500 has the shortest dimension in the direction a shown in FIG. 5 and has a surface extending in a direction perpendicular to the direction a. Here, the b direction and the c direction (c direction is orthogonal to the b direction) parallel to this surface are the vertical and horizontal directions of the elastic member 500, respectively, and the a direction is the height or thickness of the elastic member 500. The dimension of the elastic member 500 in the b direction corresponds to the width direction of the pressure belt 10, and the c direction of the elastic member 500 corresponds to the length direction of the pressure belt 10. The stretchable member 500 is preferably formed so as to be disposed in the air bag with no gap between the b direction and the c direction. Moreover, the thickness of a direction is 5 mm in this embodiment, for example.

  As shown in FIG. 3, the elastic member 500 is accommodated in the air bag 400 in such a posture that a wide surface contacts the surfaces of the urethane sheets 411 and 412. In a state where the air bag 400 is disposed on the belt main body 100, the length directions of the elastic member 500 and the air bag 400 are substantially aligned with the length direction of the belt main body 100.

  Thus, the air bag is in a state where the elastic member 500 is put in the air bag 400 and no external force is applied to the air bag 400, for example, the pressure belt 10 is not used (hereinafter referred to as non-use). 400 swells by the volume of the elastic member 500.

  As shown in FIG. 3, in a state where the elastic member 500 is accommodated in the air bag, the interval between the urethane sheets constituting the air bag 400 is widened by the thickness of the elastic member 500. For example, the air bag 400 is inflated from the state where the elastic member 500 is not present, about 5 mm. In addition, the dimension of the expansion-contraction member 500 of a, b, c direction is not limited to this. The elastic member 500 may be configured in a block shape as shown in FIG. 6, for example.

  As shown in FIG. 1, an annular member 200 is provided at the end of the belt main body 100 on the accommodating portion side where the air bag 400 is disposed. The annular member 200 includes a rod-shaped attachment portion 210 that is fixed to the belt main body 100, a rod-shaped folding portion 220 that is provided in parallel with the belt main body 100 and contacts the belt main body 100 when folding the belt main body 100, and the attachment portion 210 and the folding portion. A pair of rod-like connecting portions 230 and 240 that connect both ends of 220, and is formed in a rectangular frame shape.

  The attachment portion 210 is put in a hole formed in the end portion of the belt main body 100. The hole is formed by covering an end of the belt main body with a sheet-like member that is formed to have the same width as that of the belt main body 100. Hereinafter, this sheet-like member is referred to as a sheet-like member 140.

  The opening 250 of the annular member 200 functions as a belt passage through which the belt main body 100 can be passed from the front end portion. The annular member 200 is not limited to resin, but may be metal.

  In order to maintain the ring-like shape formed through the front end of the belt main body 100 at the belt through hole, a surface fastener member 300 is provided outside the belt main body 100 as shown in FIG. The surface fastener member 300 includes a first fastener portion 310 having a plurality of loop-shaped members 311 and a second fastener portion 320 having a plurality of hook-shaped members 321 hooked on the loop-shaped members 311. . The first fastener portion 310 is provided from a position near one end of the belt main body 100 to a predetermined position more than half, and the second fastener portion 320 is provided at a position near the other end of the belt main body 100. ing.

  The connecting tube 20 is a rubber tube that can be restored even if it is bent. As shown in FIG. 1, one end of the connecting tube 20 is connected to the air bag 400, and the other end is connected to the measuring instrument 30.

  Each end portion of the connecting tube 20 is connected to the air bag 400 and the measuring instrument 30 by using a connecting member such as a coupler and a joint (not shown) so as to be detachable and secure sealing properties.

  The connecting tube 20 that connects the inlet / outlet portion 415 of the air bag 400 and the connecting portion of the measuring instrument 30 does not include a branching path that distributes the internal air along the way, for example, a branching portion that is trifurcated. In a state where the air bag 400 and the measuring instrument 30 are connected by the connecting tube 20, an airtight state is ensured from the air bag 400 through the connecting tube 20 to the inside of the mounting portion of the measuring instrument 30.

  The measuring instrument 30 measures the pressure of air transmitted through the connection tube 20 in accordance with the deformation of the air bag 400. The measuring instrument 30 is not limited to an analog type.

(Configuration example of pressure belt)
In the case of an arm pressure belt, the belt body 100 is configured with a width of 3 cm and a total length of 37 cm, the air bag 400 is configured with a width of 3.5 cm and a total length of 20 cm, and the elastic member 500 is made of a high-repulsion member. The thickness is 5 mm, the width is 3 cm, and the total length is 20 cm. In the case of a pressure belt for legs, the belt body 100 is configured with a width of 5 cm and a total length of 57 cm, the air bag 400 is configured with a width of 5.5 cm and a total length of 40 cm, and the expansion / contraction member 500 is formed by a high resilience member. The thickness is 5 mm, the width is 5 cm, and the total length is 40 cm.

  Next, the usage method of the pressurization instrument 1 which concerns on this embodiment is demonstrated. First, the connecting tube 20 is connected to the pressure belt 10 and the measuring instrument 30. Next, the pressure belt 10 is applied to a pressure target such as an arm or a leg. At this time, the inside of the belt main body 100 in which the air bag 400 inflated by the elastic member 500 is disposed is applied to the object to be pressurized.

  The belt main body 100 is made to make a round around the object to be pressurized, the leading end side that is an excessive portion is passed through the opening 250 of the annular member 200, and is folded back to the opposite side by hitting the folded portion 220 of the annular member 200. The second fastener part 320 provided outside the front end portion of the folded belt main body 100 is hooked on the first fastener part 310 provided outside the belt main body 100 in the region in which the air bag 400 is accommodated, and the pressure belt. 10 is attached to the object to be pressurized.

  When the belt is attached, the air bag 400 inflated by the elastic member 500 is sandwiched between the attachment object and the core 110 of the pressure belt. The air bag 400 is compressed and deformed according to whether the belt body 100 is tightened or not, that is, the length of the belt body 100 to be folded back.

  The inflated air bag 400 is crushed together with the expansion / contraction member 500, and air is pushed out from the air bag through the inlet / outlet portion 415 to the measuring instrument side. When the air bag 400 is crushed, the pressure increases. The measuring instrument 30 measures this pressure. The wearer adjusts the measurement value to a desired value, and performs training or the like without removing the measuring device 30 from the belt main body 100 or without removing it.

  The connecting tube 20 may be fixed to the belt main body 100 with a holder member 600 shown in FIG. The holder member 600 forms a first cloth piece 610 that is detachably attached to the outside of the belt body 100 and a hole 625 that is attached to the first cloth piece 610 and through which the connecting tube 20 passes. 2 cloth pieces 620, and a knob 630 attached to the end of the first cloth piece 610. The first cloth piece 610 has a hook-and-loop fastener having a plurality of hook-shaped members 321 on the back side. The hook and loop fastener is hooked on the first fastener portion 310, and the holder member 600 is fixed to the belt main body 100.

  When the connecting tube 20 is separated from the air bag 400, the use of a joint such as a coupler having a function of restricting the inflow of air in the air bag facilitates the separation work, but without using such a joint. Alternatively, the air bag 400 may be maintained in a state where the air bag 400 is inflated by tying a knot at the tubular entrance / exit or by firmly sandwiching it with a clip or the like.

  In FIG. 4, a short tube is shown as the entrance / exit part 415, but when one end of the connection tube 20 is integrally formed with the air bag 400 as the entrance / exit part 415, the joint of FIG. At 700, only the instrument 30 may be separated.

  As described above, according to the pressurizing device 1 according to the present embodiment, it is not necessary to measure pressure before actual training using the conventional analog pressurizing device.

  In addition, with the conventional analog-type pressurizing device, if the air bag used when measuring the pressure was removed, the pressure acting on the pressurization target during actual training varied in intensity and in the preparation stage. In the pressurizing instrument 1 of the embodiment, since only the measuring instrument 30 is removed, the occurrence of such variations can be reduced.

  Furthermore, this embodiment is convenient because it can be shifted to exercise without removing the air bag 400.

Further, conventionally, an operation for increasing the pressure by using a pump member for supplying air to the air bag has been required. However, in the pressurizing device 1 of the present embodiment, the pressurization target is tightened and the pressure target is tightened. Can be measured. At the time of measurement, according to the pressurizing instrument 1 of the present embodiment, the air bag 400 is arranged in two-thirds of the circumference around the arm or leg to be pressurized , and the expandable member 500 is further provided with the air bag 400. Since it is provided in the inside, it is possible to relax the tightening force acting on the object to be pressurized.

  Since pressure is not measured with a pressure belt equipped with electronic instruments such as sensors, the pressure device 1 can be manufactured at low cost.

(Second Embodiment)
Next, a pressurizing device according to a second embodiment of the present invention will be described. FIG. 8 is a view showing the pressurizing device 2 according to the second embodiment. In the pressurizing device 2 according to the second embodiment, the belt main body 100A is different from the configuration of the belt main body 100 of the first embodiment. The belt main body 100 </ b> A includes an abutting portion 135 so that the second stretch material 130 comes into contact with the object to be pressed on the surface.

  9 shows the back side of the second stretch material 130 in contact with the air bag 400, and FIG. 10 is a cross-sectional view taken along the line BB of FIG. The contact portion 135 is provided on the back side of the second stretch material 130 that comes into contact with the air bag 400. The abutting portion 135 is a thin member having a planar shape, and for example, a thin rubber piece or the like is used. The contact portion 135 and the second stretch material 130 are stitched together.

  As shown in FIG. 9, the abutting portion 135 is narrower than the second stretch material 130 and is formed in an elongated rectangular shape. The contact portion 135 is stitched to the second stretch material 130 as shown by the stitches 138 arranged in a zigzag manner in FIGS. 8 and 9.

  The zigzag stitches change the direction at a predetermined interval in the length direction of the second stretch material 130, and change the direction (a portion surrounded by a circle of reference numeral 138A in FIG. 9) and a valley portion. (A portion surrounded by a circle denoted by reference numeral 138 </ b> B in FIG. 9) is arranged close to the edge in the width direction of the contact portion 135.

  According to the pressurizing device 2 of the present embodiment, when the belt main body 100A is mounted, the second stretch that forms the surface of the portion that contacts the pressurizing object following the movement of the pressurizing belt, particularly the portion that accommodates the air bag 400. Generation of wrinkles or the like in the material 130 can be suppressed. Therefore, the abutting portion 135 spreads in a planar shape inside the pressure belt 10 provided with the accommodating portion, and comes into contact with the arm to be pressurized at this portion, so that the force for tightening from the pressure belt to the pressure subject is increased. It is possible to prevent a reduction in the effect of suppressing blood flow due to variation due to generation of wrinkles or the like.
