(1st Embodiment)
FIGS. 1 and 2 are views for explaining a hemostatic aid 100 according to a first embodiment of the present invention.

  The hemostatic aid 100 according to the present embodiment includes a distal radial artery (the puncture site P in FIGS. 1 and 2) that runs on the fingertip side of the snuff box on the radial artery side of the artery running on the back side of the patient's hand H. ) Is used to assist hemostasis at the puncture site of the living body formed in (see). In addition, the radial artery in the snuff box is the radial artery at the site located between the extensor tendon extensor tendon and the extensor pollicis longus on the distal side of the radial artery (Netter, 4th edition, anatomical key). Radial artery in a cigarette holder), hereinafter referred to as s-RA. The distal radial artery is a dorsal carpal branch of the radial artery, a radial artery located between the extensor pollicis longus tendon and the extensor carpi radialis longus tendon, and is hereinafter referred to as d-RA.

  In addition, although the case where the right hand is punctured is shown as an example in the drawings, the target of the hemostatic aid 100 is not limited to the right hand, and may be the left hand. In the present specification, “assist” means that the first dorsal skeletal muscle M (see FIG. 2) located between the thumb and the index finger is pressed to make the puncture site easier to stop bleeding, and the vicinity thereof is in the thickness direction. Z is a state of being raised.

  The hemostatic aid 100 has a mounting section 10 and a holding section 20, if outlined with reference to FIG. The details will be described below.

(Mounting part)
As shown in FIG. 1, the mounting unit 10 includes a first mounting unit 11 that can be mounted on the thumb of the hand and a second mounting unit 12 that can be mounted on the index finger of the hand.

  The first mounting part 11 is configured as a finger sack that can be mounted on the thumb, and the second mounting part 12 is configured as a finger sack that can be mounted on the index finger. The first mounting part 11 and the second mounting part 12 are formed in accordance with the shape of a general adult thumb or index finger. Of course, the specifications of the first mounting portion 11 and the second mounting portion 12 are not limited to the above, and the shapes and the like can be appropriately changed according to the target person, such as for a child or a woman.

  The material of the mounting portion 10 is not particularly limited as long as the material has flexibility. For example, besides natural rubber, butadiene rubber, styrene-butadiene rubber, isoprene rubber, ethylene-propylene rubber, butyl rubber, chloroprene rubber, nitrile rubber, acrylic rubber, urethane rubber, silicone rubber, fluorine rubber, polyether rubber, and many others Synthetic rubber such as sulfurized rubber and chlorosulfonated polyethylene rubber can be used as a main raw material. Further, not only a single rubber component but also a mixture of two or more rubber components may be used as a main raw material. Further, the mounting section 10 may have a single-layer structure or a laminated structure including a plurality of layers made of different rubber components.

(Holding part)
The holding unit 20 holds the thumb and the index finger with the mounting unit 10 in contact with each other on one plane XY. In the present embodiment, the holding unit 20 includes a pair of magnet members 21 and 22 that hold the thumb and the index finger in contact with each other on the plane XY by magnetic force.

  As shown in FIG. 1, the magnet member 21 is attached to a side surface of the first attachment portion 11 (near the terminal phalanx at the time of attachment). The magnet member 22 is attached to the side surface of the second attachment portion 12 (near the index finger base phalanx at the time of attachment) so as to face the magnet member 21 when the attachment portion 10 is attached.

  However, the shape and position of the magnet members 21 and 22 are not particularly limited to the embodiment illustrated in FIG. 1 as long as the thumb and the index finger can be brought into contact on one plane XY by the magnet member 21 contacting the magnet member 22. . In FIG. 1, the magnet member 21 is attached to the distal end of the first mounting portion 11 (near the distal phalanx at the time of mounting), and the magnet member 22 is mounted near the base of the second mounting portion 12 (near the index finger joint at the time of mounting). I have. The magnet members 21 and 22 correspond to a magnetic part in this specification. In the present embodiment, the magnet members 21 and 22 have a circular shape or the like, and are configured to be provided in a relatively limited narrow range.

  Thereby, the puncture site or the periphery of the puncture site is held close to one plane XY as shown in FIG. 2 by the magnetic force of the magnet members 21 and 22.

  Here, "holding in a state of being in contact on one plane" means that the puncture site between the thumb and the index finger of the hand and the vicinity thereof are applied without any force by the patient himself to easily perform hemostasis. This means that the dorsal skeletal muscle M (see FIG. 2) can be raised in the thickness direction Z. As an example, there is a case where a hand is placed on a substantially flat table, and in that state, the thumb and the index finger are brought into contact with each other via the mounting section 10 along the surface of the table.

  However, if the thumb and the index finger can be brought into contact with each other to raise the puncture site between the thumb and the index finger and the first dorsal skeletal muscle M (see FIG. 2) surrounding the puncture site in the thickness direction Z, the surface of the platform is not necessarily changed. You do not need to use it. In the present embodiment, as described above, the magnet member 21 is provided on the side surface of the first mounting portion 11, and the magnet member 22 is provided on the second mounting portion 12 on the side surface facing the magnet member 21. With this configuration, the thumb and the forefinger can be brought into contact on the one plane XY via the mounting portion 10 without using a flat base.

  In other words, “holding in a state of contact on one plane” means, in other words, thumb and forefinger along the palm or sides of the thumb and forefinger facing each other via the mounting portion 10. It means that it is kept in contact. Note that the “contact state on one plane” does not include, for example, a state where the thumb is placed on the palm.

  FIG. 13 is a plan view of the hemostatic aid 100g according to the modification of FIG. 5 as viewed from the fingertip side. In the third embodiment, it has been described that the mounting portion 10b is made of one kind of material such as rubber. However, the material is not limited to this, and as shown in FIG. 13, the material of the back side 10h and the palm side 10j of the mounting part 10g may be formed of different materials.

  At this time, by forming the material of the palm side 10j from a material that is relatively harder than the material of the back side 10h of the hand, the thumb and the index finger can be easily brought into contact along the plane XY (palm). Thus, the first dorsal skeletal muscle M is held in a state of being raised in the thickness direction Z, so that a compressive force can be easily applied to the site, and a state in which hemostasis is easily performed can be achieved.
