  Note that the curved plate 4 may be one that does not have an uncurved portion like the central portion 41, that is, one that is curved over its entire length.

  A balloon 5 made of a flexible material is connected to the band 2. The balloon 5 is expanded by injecting a fluid (a gas such as air or a liquid) and compresses the puncture site 510 of the wrist 500.

  The balloon 5 is located closer to one end side in the longitudinal direction of the curved plate 4 held by the band 2. That is, in the illustrated configuration, the balloon 5 is positioned so as to overlap with the substantially right half side of the curved plate 4 in FIG.

  The constituent material of the balloon 5 is not particularly limited as long as the puncture site 510 can be visually recognized. For example, the same constituent material as that of the band 2 described above can be used. The balloon 5 is preferably made of the same or the same kind of material as that of the band 2. Thereby, joining with the strip | belt body 2 by melt | fusion can be performed easily, and it can manufacture easily.

  The balloon 5 is preferably substantially transparent (visible light transmissive). Thereby, the puncture site 510 can be reliably recognized from the outside, and the marker 7 described later can be easily aligned with the puncture site 510.

  The structure of the balloon 5 can be formed into a bag shape by sealing the edge of a sheet material made of the above-described material by a method such as fusion or adhesion. In the illustrated configuration, the balloon 5 has a rectangular shape when not expanded.

  Such a balloon 5 is connected to the belt body 2 through a connecting part 11 having flexibility. In the embodiment, the balloon 5 is connected to the band 2 via the connecting portion 11 only on the side that is offset from the curved plate 4, that is, on the right side in FIG. 1. The substantial length of the connecting portion 11 is made relatively short, whereby the balloon 5 is anchored at a position offset from the curved plate. The connecting portion 11 is preferably made of the same material as the balloon 5.

By providing such a marker 7 on the balloon 5, the balloon 5 can be easily aligned with the puncture site 510. Then, the leakage of blood and the occurrence of hematoma due to the displacement of the balloon 5 are suppressed.

  As shown in FIG. 1, the marker 7 is preferably provided at the center of the balloon 5. Thereby, since the center part of the balloon 5 can be aligned with the puncture part 510, when the balloon 5 is expanded, the pressing (compression) force of the balloon 5 acts on the puncture part 510 with certainty. To do.

  The shape of the marker 7 is not particularly limited, and examples thereof include a circle, a triangle, a quadrangle, and the like. In FIG.

  The marker 7 may be provided on the inner surface side of the balloon 5, that is, on the surface side in contact with the puncture site 510 of the balloon 5.

  Further, the marker 7 may be provided not on the balloon 5 but on the band 2 or the curved plate 4 or the auxiliary balloon 6 described later. Also in this case, it is preferable to provide the marker 7 so as to overlap the central portion of the balloon 5.

  As shown in FIG. 1, the balloon 5 is connected to an injection portion 8 for injecting a fluid into the balloon 5. The injecting portion 8 has a flexible tube 81 whose proximal end is connected to the balloon 5 and whose lumen communicates with the inside of the balloon 5, a bag body 82 installed at the distal end of the tube 81, The tubular connector 83 is connected to the bag body 82.

  When the balloon 5 is expanded (expanded), a distal end protruding portion of a syringe (not shown) is inserted into the connector 83, the pusher of the syringe is pushed, and the fluid in the syringe is injected into the balloon via the injecting portion 8. Inject into 5. After injecting the fluid into the balloon 5, when the tip of the syringe is removed from the connector 83, the check valve built in the connector 83 is closed to prevent the fluid from being exposed, and the balloon 5 is maintained in an expanded state. The

  As shown in FIG. 2, an auxiliary balloon 6 made of a flexible material is provided between the curved plate 4 and the balloon 5 so as to overlap the balloon 5. The auxiliary balloon 6 functions as a pressing member that presses the balloon 5.

  The auxiliary balloon 6 presses the balloon 5 substantially in the direction toward the center portion 520 of the wrist 500 as indicated by an arrow f in FIG. 2 due to the pressure of the fluid filled therein. By receiving such a pressing force from the auxiliary balloon 6, the balloon 5 moves the puncture site 510 in a vertical direction from top to bottom as shown by an arrow F in FIG. 2 (perpendicular to the surface of the wrist 500. Not in the right direction) but in an inclined direction (a direction toward the central part 520 of the wrist 500). As a result, the present invention provides a superior hemostatic effect as compared with the case where the puncture site 510 is pressed (pressed) in a vertical direction from top to bottom.

  The constituent material of the auxiliary balloon 6 is not particularly limited as long as it can visually recognize the puncture site 510, and for example, the same constituent material as that of the band 2 described above can be used. The auxiliary balloon 6 is preferably substantially transparent (visible light transmissive). Thereby, the puncture site 510 can be reliably recognized from the outside, and the marker 7 can be easily aligned with the puncture site 510.

  In the embodiment, the auxiliary balloon 6 has a width in the longitudinal direction of the band 2 that is smaller than that of the balloon 5, so that the size of the auxiliary balloon 6 is smaller than that of the balloon 5. Press on. Thereby, the direction of the pressing force F from the balloon 5 to the puncture site 510 can be inclined more reliably.

  Furthermore, in the embodiment, as described above, the curved plate 4 has the curved portion 42 having a smaller radius of curvature than the central portion 41 on the side where the balloon 5 is offset (the right side in FIG. 2). Then, the auxiliary balloon 6 contacts the curved portion 42 of the curved plate 4 or a portion on the right side in FIG. 2 (via the belt 2). Thereby, the direction of the force that the auxiliary balloon 6 receives from the curved plate 4, in other words, the normal direction of the curved plate 4 where the auxiliary balloon 6 contacts (via the band 2) is the center of the wrist 500. It will be inclined in a direction toward 520. As a result, the direction of the pressing force f and the pressing force F can be tilted more reliably.

  In the embodiment, a part of the balloon 5 and a part of the auxiliary balloon 6 are joined to each other by a method such as fusion or adhesion. A communication portion (opening portion) 12 that connects the inside of the balloon 5 and the inside of the auxiliary balloon 6 is formed at the joint portion. Accordingly, when the liquid is injected into the balloon 5 as described above, a part of the injected fluid flows into the auxiliary balloon 6 through the communication portion 12, and the auxiliary balloon 6 is expanded as the balloon 5 is expanded. To do. Thereby, both can be expanded by one operation and it is excellent in operativity.

  Such an auxiliary balloon 6 is connected to the band body 2 on the same side as the connecting portion 11 of the balloon 5 (right side in FIG. 2) via the fixing portion 13. As a result, the auxiliary balloon 6 is inclined more easily and reliably, so that the pressing force f against the balloon 5 acts in a direction in which the balloon 5 is inclined (a direction in which the balloon 5 is directed substantially toward the center portion 520 of the wrist 500). It becomes easy and a better hemostatic effect can be obtained.

  In the present invention, the pressing member that presses the balloon 5 is not limited to the auxiliary balloon 6 and is formed of, for example, a sponge-like substance, an elastic material, a fiber aggregate such as cotton, or a combination thereof. It may be a member such as a pad.

  In the present invention, the wearing time display member 9 is affixed to the portion of the outer surface of the band 2 wound around the wrist 500 where the curved plate 4 is held and the curved plate 4 does not overlap the balloon 5. In this part of the band 2 inside the wrist, the curved plate 4 is a base, so that description is easy. The attachment position of the wearing time display member may be the outer surface of the band 2 at the portion of the flexible male side fastener 31 that is easy for a nurse to describe. Moreover, the wearing time display member 9 is non-transparent.

  On the wearing time display member 9, the doctor can clearly indicate the items to be sent such as the patient name, catheter size, hemostasis start time, and hemostasis end time.

  Next, the usage method of the hemostatic instrument 1 provided with the wearing time display means will be described.

[1]
Before the hemostatic device 1 having the wearing time display means is attached to the wrist 500, the balloon 5 and the auxiliary balloon 6 are not expanded. In the case of the wrist 500, the puncture site 510 to the artery is usually at a position offset toward the thumb side inside the wrist 500 (the side where the tendon is present). Usually, an introducer sheath is placed at the puncture site 510. The band 2 is loosely wrapped around the wrist 500 in a state where the introducer sheath is indwelled, and the balloon 5 is aligned so that the marker 7 provided on the balloon 5 overlaps the puncture site 510, so that the band 2 The male side surface fasteners 31 are overlapped and fixed to the female side surface fasteners 32 in the vicinity of both ends.
