  First, the configuration of the hemostatic band 10 will be described with reference to FIGS. 1 and 2.

  FIG. 1 is a perspective view showing a hemostatic band 10 according to the first embodiment. FIG. 2 is an exploded perspective view showing the hemostatic band 10 of FIG. 1 disassembled for each member.

  The band 11 is formed in an elongated shape and is wound around a hemostatic site (for example, the puncture site 100b or 200b of the radial artery) of the limb (for example, the right wrist 100a or the left wrist 200a).

  The band 11 includes a winding part 11a that is wound around the limb (the right wrist 100a or the left wrist 200a) and a holding part 11b that holds the curved plate 12 on the winding part 11a. The winding part 11a is made of a flexible polyvinyl chloride or the like and is formed in a long shape. The winding part 11a is transparent at least with respect to light having a wavelength in the visible light region. The holding part 11b is made of the same material as that of the winding part 11a, and is formed shorter than the winding part 11a. The curved plate 12 is sandwiched between the inner peripheral surface of the holding portion 11b and the outer peripheral surface of the winding portion 11a. Both ends of the holding part 11b in the short direction are joined to the winding part 11a. The joining is performed by heat welding using a crimping jig or adhesion using an adhesive. The winding portion 11 a and the holding portion 11 b are deformed at a portion in contact with the curved plate 12 along the outer shape of the curved plate 12. The winding part 11a and the holding part 11b are configured to be transparent so that the positions and overlapping states of the balloon 13 and the auxiliary balloon 14 and the hemostasis state at the puncture site can be confirmed from the outside.

  The winding part 11a of the belt 11 is joined to a hook 11c of a hook-and-loop fastener on the inner peripheral surface of one end in the short direction in order to be fixed after being wound around a limb (right wrist 100a or left wrist 200a). A loop fastener loop 11d is joined to the outer peripheral surface of the other end facing one end in the hand direction. The hook 11c is formed by providing a plurality of flanges in a matrix on a rectangular base material. The loop 11d is formed by concentrating a plurality of annular portions on a rectangular base material. The hook 11c is hooked on the loop 11d and temporarily fixed.

  The curved plate 12 is attached to the belt body 11 and is curved along the limb (the right wrist 100a or the left wrist 200a).

  The curved plate 12 is formed in a convex shape along the Y direction around which the band 11 is wound around the limb (right wrist 100a or left wrist 200a), and extends along the X direction intersecting with the Y direction around which the band 11 is wound. ing. The curved plate 12 is made of hard polyvinyl chloride or the like, and is harder than at least the wound portion 11a of the band 11. The curved plate 12 is inserted into the gap between the winding part 11a and the holding part 11b of the band 11. The curved plate 12 is transparent to at least light having a wavelength in the visible light region. By configuring the curved plate 12 together with the winding portion 11a and the holding portion 11b of the belt 11 to be transparent, it is possible to confirm the position and overlapping state of the balloon 13 and the auxiliary balloon 14 from the outside and the hemostasis status at the puncture site. And

  The balloon 13 is disposed closer to the limb (right wrist 100a or left wrist 200a) than the curved plate 12, and is inflated by injecting fluid (air), while the hemostatic site (radial artery puncture site 100b or 200b). To stop bleeding.

  One of the balloon 13 and the pressing member (auxiliary balloon 14) is selectively attached to the curved plate 12 with the belt body 11 or the belt body 11 being attached to the curved plate 12 with respect to different directions along the connected connecting portions. The layers can be stacked with different surfaces overlapping each other. The balloon 13 abuts on either the hemostatic site (puncture site 100b) of the right limb (right wrist 100a) or the hemostatic site (puncture site 200b) of the left limb (left wrist 200a).

  The balloon 13 is made of polyvinyl chloride or the like having flexibility and is formed in a bag shape. The balloon 13 includes an expansion portion 13b that expands when air is injected into a base portion 13a formed in a bag shape. The balloon 13 is connected to the relay member 15, and air is injected into the expansion portion 13 b through the relay member 15. The connection part of the balloon 13 and the relay member 15 corresponds to the refraction part K1 shown in FIG. The end portion 13 g of the balloon 13 is joined to the curved plate 12 via the winding portion 11 a of the band body 11. The balloon 13 injected with air presses the hemostatic site (radial artery puncture site 100b or 200b) while being pressed from the auxiliary balloon 14. The balloon 13 and the auxiliary balloon 14 direct the compression force on the wrist.

  The pressing member (auxiliary balloon 14) is connected to the balloon 13 and presses the balloon 13 in a direction toward the limb (right wrist 100a or left wrist 200a). Here, the pressing member (auxiliary balloon 14) is connected to the balloon 13 via a relay member 15 described later.

  The pressing member corresponds to the auxiliary balloon 14, for example. The auxiliary balloon 14 is made of polyvinyl chloride or the like having flexibility, and is formed in a bag shape. The auxiliary balloon 14 includes an expansion portion 14b that expands when air is injected into a bag-shaped base portion 14a. The base part 14 a of the auxiliary balloon 14 has a similar shape to the base part 13 a of the balloon 13. On the other hand, the expansion part 14 b of the auxiliary balloon 14 is formed smaller than the expansion part 13 b of the balloon 13. That is, the extended portion 14b is formed shorter than the extended portion 13b with respect to the direction along the winding direction of the band 11.

  The expansion portion 14b of the auxiliary balloon 14 is directed from the right side (the thumb side of the right hand 100) toward the center with respect to the puncture site 100b of the right wrist 100a or to the left side (left hand) with respect to the puncture site 200b of the left wrist 200a. It is desirable to press the expansion part 13b of the balloon 13 from the thumb side of 200) toward the center. Therefore, the extended portion 14b is provided eccentrically with respect to the base material portion 14a. That is, the extended portion 14b is provided so as to be positioned below the center position of the base material portion 14a shown in FIG. The auxiliary balloon 14 includes an injection part 14c that receives air supply from the outside at one end thereof. The base material part 14a is provided with a pipe part 14d having an elongated cylindrical shape between the injection part 14c and the extension part 14b.

  In the auxiliary balloon 14, air is injected into the expansion portion 14 b through the injection portion 14 c and the piping portion 14 d by the syringe 300 connected to the connected fluid injection portion 16. Here, unlike the balloon 13, the auxiliary balloon 14 is expanded only in the central portion corresponding to the portion provided with the expanded portion 14 b along the winding direction of the band 11, but is not expanded at both end portions. There may be almost no range of the base material portion 14a that is not the balloon 13 around the expansion portion 14b. The extended portion 14b is not a central portion, but may be other than the central portion in the Z direction in FIG. 1 as a position corresponding to a position to be pressed. An end portion 14 g of the auxiliary balloon 14 is connected to the relay member 15. A connecting portion between the auxiliary balloon 14 and the relay member 15 corresponds to a bending portion K2 shown in FIG. The air injected into the expansion part 14 b is injected into the expansion part 13 b of the balloon 13 through the piping parts 15 e and 15 f of the relay member 15. The auxiliary balloon 14 in which air is injected and the central portion is expanded presses the balloon 13.

  The relay member 15 has one end connected to the balloon 13 and the other end facing the one end connected to the pressing member (auxiliary balloon 14). The balloon 13 and the pressing member (auxiliary balloon 14) can be bent via the relay member 15.

  The relay member 15 is made of polyvinyl chloride or the like having flexibility, and is formed in a thin plate shape. The relay member 15 circulates through the balloon 13 the air injected into the auxiliary balloon 14 via the fluid injection portion 16 while connecting the balloon 13 and the auxiliary balloon 14. The relay member 15 is provided with pipe portions 15e and 15f having elongated cylindrical shapes at both ends in a direction connecting the balloon 13 and the auxiliary balloon 14 along the X direction from the central side toward the distal side. . The piping portion 15 e communicates the piping portion 14 e of the auxiliary balloon 14 and the expansion portion 13 b of the balloon 13. On the other hand, the piping portion 15 f communicates the piping portion 14 f of the auxiliary balloon 14 and the expansion portion 13 b of the balloon 13. If either one of the piping part 15e or the piping part 15f is provided, air can be circulated from the auxiliary balloon 14 to the balloon 13.

  A fluid (air) is injected into the auxiliary balloon 14 and the balloon 13 via the fluid injection part 16 to be expanded.

  The fluid injection part 16 is connected to the injection part 14 c of the auxiliary balloon 14 and is drawn out from one side of the band 11 in the short direction. The auxiliary balloon 14 and the balloon 13 are in communication with each other. The fluid injection part 16 includes a bag part 16 a into which fluid (air) is injected from the injector 300, and an introduction part 16 b that communicates with the bag part 16 a and is connected to the injection part 14 c of the auxiliary balloon 14. The bag portion 16a is made of a flexible material and is formed in a bag shape. The bag portion 16a includes a check valve. The introduction portion 16b is made of a flexible material and is formed in an elongated tubular shape.

  Next, the operation of the hemostatic band 10 will be described with reference to FIGS.

  FIG. 3 is a perspective view showing a state in which the balloon 13 and the auxiliary balloon 14 of the hemostatic band 10 of FIG. 1 are folded for the right wrist 100a. FIG. 4 is a top view showing a state where the hemostatic band 10 of FIG. 1 is wound around the right wrist 100a of the right hand 100 and the puncture site 100b of the radial artery is pressed to stop the hemostasis. FIG. 5 is an end view schematically showing the hemostatic band 10 and the right wrist 100a of FIG. 4 along the Z direction so that the puncture site 100b of the radial artery passes. FIG. 6 is a perspective view showing a state in which the balloon 13 and the auxiliary balloon 14 of the hemostatic band 10 of FIG. 1 are folded for the left wrist 200a. FIG. 7 is a top view showing a state where the hemostasis band 10 of FIG. 1 is wound around the left wrist 200a of the left hand 200 and the puncture site 200b of the radial artery is pressed to stop the hemostasis. FIG. 8 is an end view schematically showing the hemostatic band 10 and the left wrist 200a of FIG. 7 along the Z direction so that the puncture site 200b of the radial artery passes.

  A case where the hemostasis band 10 is wound around the right wrist 100a of the right hand 100 and the puncture site 100b of the radial artery is pressed to stop the hemostasis will be described with reference to FIGS.

  While maintaining the position of the balloon 13, as shown in FIGS. 3A to 3B, the relay member 15 is rotated in the clockwise direction along the Z direction in FIG. At the same time, the auxiliary balloon 14 is rotated counterclockwise along the Z direction in FIG. In this way, the balloon 13 and the auxiliary balloon 14 are overlapped with each other via the relay member 15. Next, as shown in FIGS. 3 (B) to 3 (C), the overlapped balloon 13, relay member 15 and auxiliary balloon 14 are moved counterclockwise with reference to the X direction from the central side toward the distal side. Rotate. In this way, the auxiliary balloon 14 is brought into contact with the winding portion 11 a of the band 11.

  The hemostatic band 10 is wound around the right wrist 100a of the right hand 100 as shown in FIGS. Next, air is injected into the fluid injection unit 16 using the injector 300. The air injected into the fluid injection unit 16 is injected in the order of the auxiliary balloon 14 and the balloon 13. The auxiliary balloon 14 and the balloon 13 that have been expanded by being inflated with air press the puncture site 100b of the radial artery to stop hemostasis. Here, the expansion part 14b of the auxiliary balloon 14 is displaced to the right in FIG. 5 with respect to the direction along the winding direction of the band 11 by expanding. Therefore, the hemostatic band 10 can very effectively direct the compression force on the right wrist 100a by the balloon 13 and the auxiliary balloon 14.

  The case where the hemostasis band 10 is wound around the left wrist 200a of the left hand 200 and the puncture site 200b of the radial artery is pressed to stop the hemostasis will be described with reference to FIGS.

  While maintaining the position of the balloon 13, as shown in FIGS. 6A to 6B, the relay member 15 is rotated counterclockwise along the Z direction in FIG. At the same time, the auxiliary balloon 14 is rotated in the clockwise direction along the Z direction in FIG. In this way, the balloon 13 and the auxiliary balloon 14 are overlapped with each other via the relay member 15. Next, as shown in FIGS. 6B to 6C, the overlapped balloon 13, relay member 15 and auxiliary balloon 14 are rotated clockwise with reference to the X direction from the central side toward the distal side. Let In this way, the auxiliary balloon 14 is brought into contact with the winding portion 11 a of the band 11.

  As shown in FIGS. 7 and 8, the hemostatic band 10 is wound around the left wrist 200a of the left hand 200 in the above state. Next, air is injected into the fluid injection unit 16 using the injector 300. The air injected into the fluid injection unit 16 is injected in the order of the auxiliary balloon 14 and the balloon 13. The auxiliary balloon 14 and the balloon 13 that have been expanded by being inflated with air press the puncture site 200b of the radial artery to stop hemostasis. Here, the expansion part 14b of the auxiliary balloon 14 is displaced to the left in FIG. 8 with respect to the direction along the winding direction of the band 11 by expanding. Therefore, the hemostatic band 10 can very effectively direct the compression force on the left wrist 200 a by the balloon 13 and the auxiliary balloon 14.

  According to the hemostatic band 10 of the first embodiment described above, the following effects are obtained.

  (1) The hemostatic band 10 includes a band 11, a curved plate 12, a balloon 13, and a pressing member (auxiliary balloon 14). The band 11 is formed in an elongated shape and is wound around the hemostatic site (radial artery puncture site 100b or 200b) of the limb (right wrist 100a or left wrist 200a). The curved plate 12 is attached to the belt body 11 and is curved along the limb (the right wrist 100a or the left wrist 200a). The balloon 13 is disposed closer to the limb (right wrist 100a or left wrist 200a) than the curved plate 12, and is inflated by injecting fluid (air), while the hemostatic site (radial artery puncture site 100b or 200b). To stop bleeding. The pressing member (auxiliary balloon 14) is connected to the balloon 13 and presses the balloon 13 in a direction toward the limb (right wrist 100a or left wrist 200a). Here, with either one of the balloon 13 and the pressing member (auxiliary balloon 14) attached to the belt 11 or the curved plate 12, the balloon 13 and the pressing member 14 are selectively bent in different directions along the connected connecting portions. The overlapping surfaces are different so that they can be stacked.

  According to such a configuration, the right limb (the right wrist 100a) is formed by making the surfaces of the balloon 13 and the pressing member (auxiliary balloon 14) connected to each other different from each other while selectively bending in different directions. The balloon 13 is pressed against either the hemostatic site (puncture site 100b) or the hemostatic site (puncture site 200b) of the left limb (left wrist 200a). That is, the hemostatic band 10 is formed by folding the balloon 13 and the pressing member (auxiliary balloon 14) toward the right or left side along the winding direction Y of the belt body 11 to fold the balloon 13 and the pressing member (auxiliary balloon 14). ) Is moved so that it faces the right or left side of the limb, and then pressed. In this way, the hemostatic band 10 is wound around either the right wrist 100a or the left wrist 200a without changing the direction of the band 11 to stop hemostasis at the puncture site 100b or the puncture site 200b of the radial artery. Can be used. Therefore, when the hemostatic band 10 is used as both the right wrist 100a and the left wrist 200a, it is not necessary to change the direction of the band 11 and the medical personnel can easily handle it.

  (2) Further, in the hemostatic band 10, the balloon 13 and the pressing member (auxiliary balloon 14) are thin plates in which one end is connected to the balloon 13 and the other end facing the one end is connected to the pressing member (auxiliary balloon 14). The relay member 15 can be bent.

  According to such a configuration, since the balloon 13, the relay member 15, and the pressing member (auxiliary balloon 14) are connected in this order, it is used for either the right wrist 100a or the left wrist 200a. In addition, the end of the pressing member (auxiliary balloon 14) can be brought close to the bent portions of the balloon 13 and the relay member 15. Specifically, for example, the medical staff moves the right hand while holding the band 11 of the hemostatic band 10 with the left hand and the end of the pressing member (auxiliary balloon 14) with the right hand to move the balloon 13 And the connecting portion of the relay member 15 is bent. Only by doing so, the medical staff can fold the balloon 13, the relay member 15, and the pressing member (auxiliary balloon 14) to the end without changing the hemostatic band 10 in both the left hand and the right hand. Therefore, handling of the hemostatic band 10 by medical personnel can be made very easy.

  (3) Furthermore, the hemostatic band 10 can be configured such that the balloon 13 is joined to the central portion of the curved plate 12 in the Y direction along the winding direction of the band 11. The configuration in which the balloon 13 is bonded to the band body 11 or the curved plate 12 includes a configuration in which the balloon 13 is bonded to the band body 11 and a configuration in which the balloon 13 is bonded to the curved plate 12 via the band body 11.

  According to such a configuration, the balloon 13 in which the folded pressing members (auxiliary balloons 14) are stacked is moved rightward or leftward along the Y direction with the central portion of the belt 11 or the curved plate 12 as a boundary. It is possible to compress the puncture site 100b of the right wrist 100a or the puncture site 200b of the left wrist 200a without changing the direction of the band 11 simply by moving it. That is, the hemostatic band 10 can be used to stop hemostasis at the puncture site 100b of the radial artery of the right wrist 100a or the rib of the left wrist 200a simply by switching the directions of the balloon 13 and the pressing member (auxiliary balloon 14) stacked on each other. Hemostasis of the puncture site 200b of the artery can be performed. Therefore, handling of the hemostatic band 10 by medical personnel can be made very easy.

  Further, since the adjacent members in the order of the band 11 or the curved plate 12, the balloon 13, and the pressing member (auxiliary balloon 14) via the band 11 are connected, for example, from the end of the auxiliary balloon 14 Air can be injected and the auxiliary balloon 14 initially expanded. The balloon 13 can be expanded by injecting air through the auxiliary balloon 14. Furthermore, the balloon 13 that is subjected to a large load because the limb body (the right wrist 100a or the left wrist 200a) is compressed can be fixed to the curved plate 12 having sufficient hardness via the belt body 11 or the belt body 11. Therefore, the balloon 13 can be bonded to the band 11 and firmly bonded to the curved plate 12 via the band 11.

  (6) Further, in the hemostatic band 10, the pressing member (auxiliary balloon 14) may be formed from an expansion part that is expanded by injecting a fluid.

  According to such a configuration, the gap between the wrist and the band 11 can be minimized at the stage where the hemostatic band 10 is wound around the wrist, and then the auxiliary balloon 14 can be expanded. That is, the timing for generating the pressing force on the balloon 13 and the strength of the pressing force on the balloon 13 can be set flexibly. Therefore, the hemostatic band 10 can be further easily handled by medical personnel.

  (8) Furthermore, the hemostatic band 10 may have a configuration having the fluid injection part 16. The fluid injection part 16 is connected to the balloon 13 or the pressing member (auxiliary balloon 14), and injects fluid (air) to expand it.

  According to such a configuration, the hemostatic band 10 can be used by being wound around each of the right wrist 100a and the left wrist 200a while the fluid injection portion 16 connected to the balloon 13 is disposed on the distal side, for example. . That is, as shown in FIGS. 4 and 7, even when the hemostatic band 10 is used by being wound around either the right wrist 100a or the left wrist 200a, the balloon 13 is directed from the peripheral side toward the central side.

The auxiliary balloon 34 presses the balloon 13 from an arbitrary portion along the winding direction of the belt body 11 by selectively expanding an arbitrary expansion portion 14b of the plurality of expansion portions 14b. The auxiliary balloon 34 includes, for example, two expansion portions 14b, one each for the first auxiliary balloon 34M and the second auxiliary balloon 34N.

  The first auxiliary balloon 34M and the second auxiliary balloon 34N have a similar shape and are provided adjacent to each other along the winding direction of the belt 11. Air is injected into the first auxiliary balloon 34M via the fluid injection part 16 in the order of the injection part 14c, the piping part 14d, and the expansion part 14b. Furthermore, air is injected into the balloon 13 from the expansion part 14b via the piping part 14e.

If the expansion part 14b is selected and expanded, a compression force can be effectively generated from the left end of the right wrist 100a toward the center. In such a case, it is possible to generate a compression force perpendicular to the right wrist 100a along the Z direction corresponding to the layer thickness direction of the hemostatic band with respect to the right wrist 100a.

  (9) Furthermore, in the hemostatic band 50, the fluid injection part 16 can be configured to be detachable from the pressing member (auxiliary balloon 34).

  According to such a configuration, the hemostatic band 50 can attach and detach the fluid injection part 16 only to an arbitrary expansion part 14b to be expanded among the plurality of expansion parts 14b. Therefore, the hemostatic band 50 can be made inexpensive with a simpler configuration. Furthermore, since the hemostatic band 50 is configured to include only one fluid injection part 16 as in the case of the conventional hemostatic band, the method for handling the fluid injection part 16 by medical personnel should be similar to the conventional one.

Further, the hemostatic band 80 does not include the relay member 15 that relays the balloon 13 and the pressing member (auxiliary balloon 34) and is refractable.

  According to such a configuration, the hemostatic band 80 exhibits the following operational effects in addition to the operational effects of the hemostatic band 50 described above. That is, the hemostatic band 80 has a pressing member (auxiliary balloon 34), which desirably defines the pressing direction to the balloon 13 with high accuracy, on the band 11 or the curved plate 12 serving as a positioning reference via the band 11. It is joined. Therefore, the positional accuracy of the pressing member (auxiliary balloon 34) can be improved. Furthermore, since the hemostatic band 80 has a simple configuration excluding the relay member 15, it can be inexpensive and can improve the responsiveness related to the expansion of the auxiliary balloon 34.

  The present invention is not limited to the first and second embodiments described above, and can be modified as appropriate.

  For example, in the first and second embodiments, the pressing member has been described as a configuration of an auxiliary auxiliary balloon that expands when fluid (air) is injected through the fluid injection portion and presses an adjacent balloon. However, the present invention is not limited to such a configuration. That is, in the present invention, the pressing member is also applied as a configuration having a solid columnar shape extending along the X direction while having a certain hardness and having an elliptical cross section along the Y direction and the Z direction. Is possible.

  Moreover, in 1st and 2nd embodiment, the curved plate was demonstrated as a structure embed | buried under a strip | belt body. However, the present invention is not limited to such a configuration. That is, the present invention can also be applied to a configuration in which a band is joined to both ends of the curved plate along the Y direction.

  In the first and second embodiments, the hemostatic band has been described as a configuration that stops the blood by pressing the puncture site. However, the present invention is not limited to such a configuration. That is, the present invention can also be applied to a configuration in which a hemostatic band is compressed by pressing a bleeding site caused by a laceration or the like not caused by puncture.

  In the first and second embodiments, the hemostatic band has been described as being configured to be used so that the fluid injection part is on the distal (hand side) side. However, the present invention is not limited to such a configuration. That is, the present invention can also be applied to a configuration in which the hemostatic band is arranged and used so that the fluid injection portion is on the central (heart) side.

  In the first and second embodiments, the hemostatic band is used by being wound around the wrist. However, the present invention is not limited to such a configuration. That is, the present invention can also be applied to a configuration in which a hemostatic band is wound around a limb such as an ankle or thigh to press a puncture site of a blood vessel to stop hemostasis.
