As shown in FIG. 2, the band 2 is wound around the wrist 500 so as to make a round, and is attached to the wrist 500 so that portions near both ends thereof are overlapped with each other. The band 2 is fixed (joined) by a surface fastener 3 generally called a magic tape (registered trademark) or the like at the overlapping portion.

  The constituent material of the band 2 is not particularly limited as long as the material can visually recognize the puncture site 510. For example, polyvinyl chloride, polyethylene, polypropylene, polybutadiene, polyolefin such as ethylene-vinyl acetate copolymer (EVA), Various thermoplastic elastomers such as polyesters such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), polyvinylidene chloride, silicone, polyurethane, polyamide elastomer, polyurethane elastomer, polyester elastomer, or any combination thereof (blends) Resin, polymer alloy, laminate, etc.).

  The band 2 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.

  A curved plate holding portion 21 that holds a curved plate 4 to be described later is formed at the center of the band 2. In the curved plate holding portion 21, a separate band member is fused (thermal fusion, high frequency fusion, ultrasonic fusion, etc.) or adhesion (adhesion with an adhesive or a solvent) on the outer surface side (or inner surface side), etc. By joining by this method, it becomes double, and the curved plate 4 inserted in the gap is held.

  Fixing means for fixing the band 2 in a state of being wound around the wrist 500 is not limited to the hook-and-loop fastener 3, and may be, for example, a snap, a button, a clip, or a frame member that passes the end of the band 2.

  The curved plate 4 is held by the band 2 by being inserted between the double curved plate holding portions 21 of the band 2.

  The curved plate 4 has a shape in which at least a part thereof is curved toward the inner peripheral side. The curved plate 4 is made of a material that is harder than the band 2 and maintains a substantially constant shape.

  A vent hole (not shown) disposed so as to penetrate the vent hole 22 of the band 2 is preferably provided in a portion of the curved plate 4 that does not overlap the balloon 5 described later.

  In the embodiment, the curved plate 4 has a long shape in the longitudinal direction of the band 2. As shown in FIG. 2, the central portion 41 in the longitudinal direction of the curved plate 4 has a flat plate shape with almost no curvature, and on both sides of the central portion 41, respectively, toward the inner peripheral side, And the curved board 42 curved along the longitudinal direction (circumferential direction of the wrist 500) of the strip | belt body 2 is formed. That is, the radius of curvature R2 of the curved plate 42 is smaller than the radius of curvature R1 of the central portion 41 (in the configuration shown, R1 is approximately 180 °).

  The constituent material of the curved plate 4 is not particularly limited as long as the material can visually recognize the puncture site 510. For example, acrylic resin, polyvinyl chloride (particularly hard polyvinyl chloride), polyethylene, polypropylene, polyolefin such as polybutadiene, Polystyrene, poly- (4-methylpentene-1), polycarbonate, ABS resin, polymethyl methacrylate (PMMA), polyacetal, polyacrylate, polyacrylonitrile, polyvinylidene fluoride, ionomer, acrylonitrile-butadiene-styrene copolymer, polyethylene terephthalate (PET), polyesters such as polybutylene terephthalate (PBT), butadiene-styrene copolymers, aromatic or aliphatic polyamides, fluorine-based trees such as polytetrafluoroethylene Etc. The.

  The curved plate 4 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.

  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. As for this connection part 11, the substantial length is comparatively shortened, and, thereby, the balloon 5 is propagated in the position which offset | deviated with respect to the curved board. The connecting portion 11 is preferably made of the same material as the balloon 5.

  A marker 7 is provided on the inner surface side of the balloon 5, that is, on the surface side in contact with the puncture site 510. 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 outer surface side of the balloon 5, that is, on the side opposite to the surface that contacts the puncture site 510 of the balloon 5 (the back side of the paper surface of FIG. 1).

  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.

  As shown in FIG. 1, a gap securing member 9 is connected to the band 2 via a flexible connecting portion 91. Instead of connecting the gap securing member 9 to the band 2 using the connecting portion 91, the gap securing member 9 may be fixed with a clip or the like in the vicinity of the gap securing member 9 attachment position of the band 2.

  Next, the usage method of the hemostatic instrument 1 provided with the clearance ensuring member is demonstrated.

[1]
Before the hemostatic device 1 having the gap securing member 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 wound around the wrist 500 in a state where the introducer sheath is indwelled by using the gap securing member 9 so as to follow the wrist 500 without applying a tensile force, and the marker 7 provided on the balloon 5 is punctured. The balloon 5 (band body 2) is aligned so as to overlap the region 510, and the male side surface fastener 31 and the female side surface fastener 32 are overlapped and fixed (joined) in the vicinity of both ends of the band body 2.

[2]
After the hemostatic device 1 having the gap securing member is attached to the wrist 500, the gap securing member 9 is removed, a syringe (not shown) is connected to the connector 83 of the injection portion 8, and the fluid is ballooned as described above. A predetermined amount is injected into 5 and the auxiliary balloon 6 according to the case, and the balloon 5 and the auxiliary balloon 6 are expanded.

  In the embodiment, since the band 2 is wound around the wrist 500 using the gap securing member 9 before the balloon 5 is expanded, the degree of looseness of the band 2 when the gap securing member 9 is removed is constant every time. become. Therefore, the compression force on the puncture site 510 due to the expansion of the balloon 5 when a predetermined amount of fluid is injected is kept almost constant each time.

The looseness of the band 2 when the gap securing member 9 is removed is preferably 10 to 25 mm.
If it is less than 10 mm, the pressing force on the puncture site 510 due to the expansion of the balloon 5 becomes too strong. If it exceeds 25 mm, the pressing force on the puncture site 510 due to the expansion of the balloon 5 becomes insufficient, and the puncture site 510 is detached from the balloon 5 and the band 2 is detached from the wrist 500.

[3]
When the balloon 5 and the auxiliary balloon 6 are expanded, the syringe is detached from the connector 83. Then, the introducer sheath is removed from the puncture site 510. Thereby, the balloon 5 and the auxiliary balloon 6 maintain an expanded state, and the compression state by the predetermined compression force to the puncture site | part 510 is maintained (refer FIG. 2). In this state, the balloon 5 locally presses the puncture site 510 (and its surroundings), and due to the expansion of the balloon 5 and the auxiliary balloon 6, the curved plate 4 is separated from the surface of the wrist 500 and applied to the wrist 500. It becomes difficult to touch. As a result, the puncture site 510 (and its surroundings) concentrates and receives a compression force. Before the balloon 5 is expanded after the gap securing member 9 is removed, the band 2 is wound around the wrist 500 with a predetermined length of looseness and is fixed. It is set to be. Therefore, the pressing force applied to the puncture site 510 by the balloon 5 does not apply an excessive load to the surrounding nerves and the ulnar artery.

[4]
After the introducer sheath is removed from the puncture site 510 and bleeding stops, the syringe is connected to the connector 83 again to discharge the fluid in the balloon 5, and then the hemostatic device having a gap securing member is removed from the wrist 500 to stop hemostasis. To complete.

  Depending on the size of the catheter used, the hemostasis time from the start to the end of hemostasis is 2-3 hours at least, and more than 10 hours when it is large. However, the band 2 provided with the gap securing member according to the present invention is used. Then, excessive pressure on the puncture site 510 and insufficient pressure can be prevented.

Example 1
FIG. 3 is a schematic cross-sectional view showing Example 1 of the hemostatic device provided with the gap ensuring member of the present invention.

  In Example 1, using the round bar 10 made of plastic with a diameter of φ10 mm as the gap securing member 9, the method of using the hemostatic device 1 provided with the gap securing member of the above [1] to [4] was implemented.

  When a round bar 10 having a diameter of 10 mm is attached and the belt 2 is wound without applying a tensile force so as to follow around the wrist 500, the round bar 10 is removed and the belt 2 has a length of about 15 mm. Looseness occurs.

The gap securing member 9 is not limited to a cylindrical round bar, but can be sandwiched between the wrist 500 and the hemostatic device 1 such as a rectangular bar, a square bar such as a cube, a sphere, or a triangular bar with a gently inclined truncated cone. I just need it.
(Example 2)
FIG. 4 is a schematic cross-sectional view showing a second embodiment of the hemostatic device provided with the gap ensuring member of the present invention.

  In Example 2, the gap securing member 9 is provided with the gap securing member of the above [1] to [4] using a clip 20 provided with a stopper (not shown) so that the clip length is 8 mm. The method of using the hemostatic device 1 was carried out. The stopper may have a structure in which the length of the clip can be adjusted stepwise.

  Using the clip 20, the band 2 is overlapped and clipped to a length of 8 mm, wound without applying a tensile force so as to follow around the wrist 500, and then the clip 20 is removed. A slack of about 16 mm in length occurs.

  Even when the hemostasis time by the hemostasis device 1 provided with the gap securing member of the present invention exceeds 10 hours, the puncture site can be obtained by using either the gap securing member 10 of Example 1 or the gap securing member 11 of Example 2. There was no pain, numbness or prolonged hemostasis due to insufficient compression due to excessive compression on 510.

  Moreover, although the hemostatic device provided with one gap securing member has been described in the present embodiment, a plurality of gap securing members may be provided. Thereby, the degree of compression can be adjusted in steps.

(Example 3)
FIG. 5 is a schematic cross-sectional view showing a third embodiment of the hemostatic device provided with the gap ensuring member of the present invention.

  In Example 3, hemostasis provided with the gap securing members described in [1] to [4] above using three plastic cylindrical rods 10a, 10b, and 10c having a diameter of 8 mm as the gap securing member 9. The usage method of the instrument 1 was implemented.

  When the round bars 10a, 10b, and 10c having a diameter of 8 mm are attached at equal intervals as shown in the figure, the belt 2 is wound around the wrist 500 without applying a tensile force, and then the round bars 10a, 10b, and 10c are removed. When the distance between 10a, 10b, and 10c is 8 mm, the round bar band 2 is loosened by about 15 mm in length.

  In the method of using the hemostatic device 1 having the gap securing member of [2] above, instead of removing all the three round bars 10a, 10b, 10c at the same time, for example, the balloon 5 is expanded by removing the round bars 10a, Next, when the procedure of removing the round bar 10b after a certain time has elapsed from the start of hemostasis and removing the round bar 10c after the certain time has elapsed, the degree of compression can be adjusted stepwise.

  The diameter, number, and arrangement of the round bars as the gap securing member 9 are not particularly limited. The diameters of the round bars 10a, 10b, and 10c may be different from each other.

  The gap securing member 9 is not limited to a cylindrical round bar, but can be sandwiched between the wrist 500 and the hemostatic device 1 such as a rectangular bar, a square bar such as a cube, a sphere, or a triangular bar with a gently inclined truncated cone. I just need it.

  In Example 4, three gaps 20a, 20b, and 20c provided with stoppers (not shown) so that the clip length is 2.5 mm as the gap securing member 9 are used. The method of using the hemostatic device 1 provided with the gap ensuring member of [4] was carried out. The stopper may have a structure in which the length of the clip can be adjusted stepwise.

  Using the clips 20a, 20b, and 20c, in a state where the band 2 is overlapped and clipped to a length of 2.5 mm and wound around the wrist 500 without applying a tensile force, the clip 20a, When 20b and 20c are removed, a slack of about 15 to 16 mm in length is generated in the band.

  In the method of using the hemostatic device 1 having the gap securing member of [2] above, instead of removing all the three clips 20a, 20b, 20c at the same time, for example, the clip 5a is removed to expand the balloon 5, and then hemostasis is performed. When the procedure of removing the clip 20b after a certain time has elapsed from the start and removing the clip 20c after the certain time has elapsed, the degree of compression can be adjusted stepwise.

  The clip length, number, and arrangement of the clip as the gap securing member 9 are not particularly limited. The clip lengths of the clips 20a, 20b, and 20c may be different from each other.

  As mentioned above, although the hemostatic instrument provided with the gap ensuring member of this invention was demonstrated based on embodiment of illustration, this invention is not limited to this, Each part which comprises the hemostatic instrument provided with the gap ensuring member Can be replaced with any structure capable of performing the same function. Arbitrary components may be added.
