Description

[Technical Field]

[0001] The present invention relates to a hemostatic device. [Background technology]

[0002] One known catheterization procedure involves puncturing a blood vessel in a patient's arm or hand, forming a puncture site, and introducing various types of elongated medical objects into the blood vessel to diagnose or treat the lesion. For example, Patent Document 1 discloses a hemostatic device that stops bleeding at a puncture site formed to enable access to a blood vessel (including the distal radial artery) running through the hand.

[0003] The hemostatic device of Patent Document 1 includes an expansion member that applies pressure to a puncture site formed on the patient's hand, multiple bands that secure the expansion member to the patient's body, and a support member to which the expansion member is connected. In the hemostatic device of Patent Document 1, the expansion member is composed of a balloon that can expand and contract as air or other fluid is injected and discharged. When expanding and contracting the expansion member, a doctor or nurse (hereinafter referred to as the "operator") connects a fluid injection member such as a syringe to a connector portion (air injection port) attached to the hemostatic device. The operator injects and discharges fluid into and from the expansion member by operating the fluid injection member connected to the connector portion. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] US Patent Application Publication No. 2019 / 0133602 Summary of the Invention [Problem to be solved by the invention]

[0005] For example, in catheterization procedures, a puncture site may be formed on the patient's right hand or left hand to preserve one of the patient's hands. When starting hemostasis using the hemostatic device described in Patent Document 1, the surgeon places a support member connected to an expansion member so that it overlaps the puncture site formed on either the left or right hand, then connects multiple bands to secure the expansion member to the hand. In the hemostatic device described in Patent Document 1, the connection position of the expansion member on the support member cannot be changed. Therefore, when using the hemostatic device to stop hemostasis at both the puncture site formed on the patient's right hand and the puncture site formed on the patient's left hand, it is difficult to properly position the expansion member at each puncture site.

[0006] For example, one possible solution to the above-mentioned problems is to configure a hemostatic device with multiple expansion members arranged at different positions on a support member. When a hemostatic device is equipped with multiple expansion members, the surgeon can align and position one expansion member when staunching a puncture site formed on a patient's right hand, and align and position the other expansion member when staunching a puncture site formed on the patient's left hand. This allows the hemostatic device to be used on both the left and right hands.

[0007] However, when a hemostatic device is configured with multiple expansion members as described above, it is necessary to attach the same number of connectors to the hemostatic device as the number of expansion members so that each expansion member can be expanded individually. If multiple connectors are attached to a single hemostatic device, there is a risk that the surgeon will mistakenly connect a fluid injection member to the connector when attempting to selectively expand one of the multiple expansion members. Furthermore, if multiple connectors are arranged on the support member, there is a higher risk of the patient's fingers or surrounding objects accidentally coming into contact with the connector while using the hemostatic device to stop bleeding, which reduces usability.

[0008] Furthermore, if the hemostatic device is laid out in a position where multiple connector portions overlap the puncture site when placing each expansion member at the puncture site on either the left or right hand, it becomes difficult to properly position each expansion member at the puncture site. Therefore, when a hemostatic device is configured to include multiple expansion members, it is not preferable to adopt a layout in which connector portions are individually positioned on each expansion member.

[0009] A hemostatic device can also be configured with a single connector that can switch fluid communication with each of multiple expansion members. However, if the valve structure for switching fluid communication is not carefully considered, integrating multiple valve structures into a single connector may result in an increased size of the connector. If a hemostatic device includes an excessively large connector, the connector may be positioned so that it overlaps the puncture site, making it difficult to properly position the expansion member at the puncture site, just as it would be if each expansion member had its own connector.

[0010] The present invention aims to provide a hemostatic device that can be used with both the left and right hands, has excellent usability to prevent incorrect connection of the fluid injection member, and can prevent the connector portion from interfering with the positioning of the expansion member relative to the puncture site when placing the expansion member at the puncture site. [Means for solving the problem]

[0011] (1) A device comprising: a support member configured to cover a puncture site formed on a patient's hand; a first expansion member connected to the support member and configured to be expandable by injecting a fluid; a second expansion member connected to the support member at a position different from the first expansion member and configured to be expandable by injecting a fluid; a connector portion located on the support member and configured to selectively inject the fluid into one of the first expansion member and the second expansion member; and a fixing member configured to fix the support member to the hand, wherein the connector portion is a first valve body portion located in the cavity of the tubular member; and a second valve body portion located in the cavity of the tubular member and disposed at a different position from the first valve body portion in the extension direction of the tubular member, wherein the tubular member is provided with a first opening portion located between the first valve body portion and the second valve body portion and communicating the first expansion member with the cavity of the tubular member, and a second opening portion located between the second valve body portion and a bottom of the tubular member and communicating the second expansion member with the cavity of the tubular member.

[0012] (2) The hemostatic device described in (1) above, wherein the connector portion has a stopper portion between the first valve body portion and the second valve body portion, configured to prevent a fluid injection member inserted from the first valve body portion into the inner cavity of the tubular member from passing through the second valve body portion.

[0013] (3) The hemostatic device described in (2) above, wherein the stopper portion is inserted into the inner cavity of the tubular member so as to be positioned between the first valve body portion and the second valve body portion in the extension direction of the tubular member, and the stopper portion is configured to be movable between a first position that prevents the fluid injection member from passing through the second valve body portion and a second position that allows the fluid injection member to pass through the second valve body portion.

[0014] (4) The hemostatic device described in (3) above, wherein the tubular member has an insertion hole for inserting the stopper portion into the inner cavity of the tubular member, and the stopper portion has a sealing member that prevents the fluid from leaking between the stopper portion and the insertion hole.

[0015] (5) A hemostatic device as described in (3) or (4) above, wherein the stopper portion has a position marker portion that indicates whether the stopper portion is positioned in the first position or the second position.

[0016] (6) A hemostatic device according to any one of (2) to (5), wherein the first valve body has a first insertion portion and a second insertion portion located at a position different from the first insertion portion, the second valve body has a first region through which a fluid injection member can be inserted and a second region made of a material harder than the first region and configured to prevent the fluid injection member inserted from the first valve body from being inserted into the second valve body, and the connector is configured so that when the first valve body is projected onto the second valve body, the first insertion portion is located in the second region and the second insertion portion is located in the first region.

[0017] (7) The hemostatic device described in (6) above, wherein the connector portion is disposed in the inner cavity of the tubular member and has a partition portion that prevents the fluid injection member inserted into the inner cavity of the tubular member from the first insertion portion from moving into the first region.

[0018] (8) A device for providing a puncture treatment to a patient's hand, the device comprising: a support member configured to cover a puncture site formed on the patient's hand; a first expansion member connected to the support member and configured to be expandable by injecting a fluid; a second expansion member connected to the support member at a position different from the first expansion member and configured to be expandable by injecting a fluid; a connector configured to selectively inject the fluid into one of the first expansion member and the second expansion member; and a fixing member configured to fix the support member to the hand, the connector comprising: a first member having an inner cavity; a second member located in the inner cavity of the first member and configured to be connectable to a fluid injection member; an elastic member located between the first member and the second member; and a stopper portion located on the outer surface of the first member, the first member communicating with the inner cavity of the first member. and a second opening located at a position different from the first opening in the extension direction of the first member, the second member having a hole configured to be selectively aligned with one of the first opening and the second opening, the stopper portion configured to be movable between a first position and a second position protruding beyond a base-end surface of the first member, wherein when the stopper portion is located at the first position, the hole and the second opening can be aligned in the extension direction of the first member, and when the stopper portion is located at the second position, the hole and the second opening cannot be aligned in the extension direction of the first member, and the hole and the first opening can be aligned in the extension direction of the first member.

[0019] (9) A hemostatic device as described in (8) above, which has a locking portion capable of holding the stopper portion at the first position and the second position, the locking portion having a first groove portion formed on the outer surface of the first member and extending along the extension direction of the first member, a second groove portion formed on the outer surface of the first member and extending along the circumferential direction of the first member, and a convex portion formed on the inner surface of the stopper portion and configured to be movable along the first groove portion and the second groove portion. [Effects of the Invention]

[0020] In the hemostatic device of (1) above, a fluid injection member for injecting a fluid is disposed between the first valve body portion and the second valve body portion, and by injecting a fluid from the fluid injection member, the fluid can be injected into the first expansion member through the first opening. Furthermore, in the hemostatic device, a fluid injection member for injecting a fluid is disposed between the second valve body portion and the bottom of the tubular member, and by injecting a fluid from the fluid injection member, the fluid can be injected into the second expansion member through the second opening. Therefore, the hemostatic device can selectively expand either the first expansion member or the second expansion member by injecting a fluid while aligning the position of the fluid injection member with one of the first opening and the second opening in the extension direction of the tubular member. Therefore, the hemostatic device does not need to include a connector portion dedicated to expanding the first expansion member and a connector portion dedicated to expanding the second expansion member. Therefore, the hemostatic device described above can prevent problems such as an operator incorrectly connecting a fluid injection member when the hemostatic device has multiple connectors, and can prevent reduced usability due to unintentional contact of the connectors with the patient's fingers or surrounding objects caused by multiple connectors arranged on the support member. Furthermore, the hemostatic device described above can be used on both left and right hands by expanding the first or second expansion member while the first or second expansion member is selectively arranged at a puncture site formed on the right hand or a puncture site formed on the left hand. Furthermore, the hemostatic device described above has a first opening communicating with the first expansion member and a second opening communicating with the second expansion member arranged at different positions in the extension direction of the tubular member. Therefore, the hemostatic device can adopt a compact structure in which the connectors are not unnecessarily large in the extension direction of the support member (the direction in which the support member expands in a plan view). This prevents the connectors from being arranged so that they overlap with the expansion members in the planar direction. Therefore, the hemostatic device described above can appropriately position and place the first expansion member or the second expansion member at the puncture site formed on the right or left hand without being obstructed by the connector portion.Furthermore, by adopting the above-described compact structure in the connector portion of the hemostatic device, the surgeon can adjust the amount of fluid injected into the first expansion member or the second expansion member while visually checking the bleeding condition from the puncture site.

[0022] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following description does not limit the technical scope or meaning of terms described in the claims. Furthermore, the dimensional proportions in the drawings are exaggerated for the convenience of explanation and may differ from the actual proportions.

[0023] (First embodiment) 1 to 13 are diagrams illustrating a hemostatic device 10 according to this embodiment. Figures 14 to 18 are diagrams illustrating an example of how the hemostatic device 10 is used.

[0024] The hemostatic device 10 can be used, for example, as shown in Figures 15, 16, 17, and 18, to stop bleeding at a puncture site p (hereinafter also referred to as "puncture site p") formed in a hand H located distal (toward the fingers) of a patient's forearm A when removing a sheath tube 710 of an introducer 700 that has been placed at the puncture site p.

[0025] In this embodiment, the puncture site p is exemplified by a first puncture site p1 and a second puncture site p2. The first puncture site p1 is a puncture site formed in artery B1 (hereinafter also referred to as "blood vessel B1"; see FIG. 16) located in the snuff box of the palmar artery running along the back side of the patient's right hand HR, located distal to the patient's forearm A. The second puncture site p2 is a puncture site formed in artery B2 (hereinafter also referred to as "blood vessel B2"; see FIG. 18) located in the snuff box of the palmar artery running along the back side of the patient's left hand HL, located distal to the patient's forearm A. The snuff box is a cavity in the hand located near the radius when the patient spreads the thumb of the hand H.

[0026] <Hemostasis device 10> As shown in Figures 1, 2, 15, 16, 17, and 18, the hemostatic device 10 generally comprises a support member 100 configured to cover the puncture site p, a first expansion member 210 connected to the support member 100 and configured to be expandable by injection of a fluid, a second expansion member 220 connected to the support member 100 at a position different from the first expansion member 210 and configured to be expandable by injection of a fluid, a connector portion 300 located on the support member 100 and configured to allow fluid to be selectively injected into one of the first expansion member 210 and the second expansion member 220, and a fixing member 400 configured to fix the support member 100 to the hand H.

[0027] <Support member 100> As shown in FIGS. 5, 7, and 11, the support member 100 is made up of a plate-like member to which a first expansion member 210 and a second expansion member 220 are connected.

[0028] The first expansion member 210 and the second expansion member 220 are connected to the inner surface 100a of the support member 100. The inner surface 100a of the support member 100 is the surface that is placed on the body surface side of the patient's hand H when the hemostatic device 10 is attached to the patient's hand H (see Figures 16 and 18).

[0029] 5, 7, and 11, part of the upper end of connector portion 300 is disposed on the outer surface 100b side of support member 100, and part of the lower end (bottom portion 316 side) of connector portion 300 is disposed on the inner surface 100a side of support member 100. Outer surface 100b of support member 100 is the surface located opposite to inner surface 100a.

[0030] As shown in Figures 3 and 4, the planar shape of support member 100 can be formed, for example, into a substantially trapezoidal shape with rounded corners. As shown in Figures 5, 7, and 11, the side shape (cross-sectional shape) along the width direction of support member 100 (left-right direction in Figures 3, 4, and 5) can be formed, for example, into a shape that is gently convexly curved toward approximately the center position c1 of support member 100 in the width direction. Note that the planar shape and cross-sectional shape of support member 100 are not particularly limited as long as they can be positioned to cover the puncture site p when hemostatic device 10 is worn on the patient's hand H (see Figures 15 and 17).

[0031] The support member 100 can be made of, for example, a material having a predetermined hardness. Examples of materials that can be used to make the support member 100 include acrylic resin, polyvinyl chloride (particularly hard polyvinyl chloride), polyolefins such as polyethylene, polypropylene, and polybutadiene, polystyrene, poly-(4-methylpentene-1), polycarbonate, ABS resin, polymethyl methacrylate (PMMA), polyacetal, polyacrylate, polyacrylonitrile, polyvinylidene fluoride, ionomer, acrylonitrile-butadiene-styrene copolymer, and polyethylene terephthalate (PET).

[0032] <First expansion member 210> The first expansion member 210 can be configured, for example, by a resin balloon having an internal space 215 into which a fluid such as air can be injected. Fig. 5 shows the first expansion member 210 in an unexpanded state, and Fig. 7 shows the first expansion member 210 in an expanded state.

[0033] 5 and 6, the first expansion member 210 can be configured as a balloon in which an internal space 215 into which a fluid can be injected is defined between the inner surface 100a of the support member 100 and the first expansion member 210 by fixing the edge of a membrane-like member to the support member 100. However, there are no particular limitations on the specific structure of the first expansion member 210. The first expansion member 210 can be configured, for example, as two membrane-like members joined together, with the internal space 215 defined between the two membrane-like members, or as a single bag-like member with the internal space 215 defined inside.

[0034] 5, the first expansion member 210 and the connector section 300 are connected by a first tube 510 having an inner cavity 511. One end of the first tube 510 is constantly in communication with the internal space 215 of the first expansion member 210. The other end of the first tube 510 is constantly in communication with the first opening 312 of the tubular member 310 of the connector section 300 (see FIGS. 8 and 12).

[0035] The membrane-like member that constitutes the first expansion member 210 can be fixed to the inner surface 100a of the support member 100 by, for example, fusion or adhesion.

[0036] 3 and 4, the first expansion member 210 can be configured to have a substantially trapezoidal shape in plan view. The planar shape of the first expansion member 210 is not particularly limited as long as it can apply a predetermined compressive force to the puncture site p. There are also no particular limitations on the cross-sectional shape of the first expansion member 210 before and after expansion, or the position at which the first expansion member 210 is disposed in the support member 100.

[0037] 3, 4, 5, 14, and 15, the first expansion member 210 has a marker portion 218 for aligning the first expansion member 210 with the puncture site p. The marker portion 218 can be configured, for example, by printing a predetermined shape and color on the underside of the first expansion member 210 (the surface that is placed facing the body surface of the hand H), or by attaching a sticker that forms the marker portion 218.

[0038] The position of the first expansion member 210 that overlaps in plan view with the position where the marker portion 218 is formed can be formed transparent or semi-transparent. Furthermore, the position of the support member 100 that overlaps in plan view with the position where the marker portion 218 is formed can be formed transparent or semi-transparent. By forming predetermined positions of the first expansion member 210 and predetermined positions of the support member 100 transparent or semi-transparent as described above, the operator can easily visually confirm the position of the marker portion 218 from the outer surface 100b side of the support member 100 when placing the first expansion member 210 at the puncture site p, as shown in FIG. 14 .

[0039] <Second expansion member 220> The second expansion member 220 can be configured, for example, by a resin balloon having an internal space 225 into which a fluid such as air can be injected. Fig. 5 shows the second expansion member 220 in an unexpanded state, and Fig. 11 shows the second expansion member 220 in an expanded state.

[0040] As shown in FIGS. 5 and 11 , the second expansion member 220 can be configured as a balloon in which an internal space 225 into which a fluid can be injected is defined between the inner surface 100a of the support member 100 and the second expansion member 220 by fixing the edge of a membrane-like member to the support member 100. However, there are no particular limitations on the specific structure of the second expansion member 220. The second expansion member 220 can be configured, for example, by joining two membrane-like members together to define the internal space 225 between the two membrane-like members, or by a single bag-like member in which the internal space 225 is defined inside. Furthermore, the second expansion member 220 may have the same structure as the first expansion member 210, or it may have a different structure from the first expansion member 210.

[0041] 5, the second expansion member 220 and the connector section 300 are connected by a second tube 520 having an inner cavity 521. One end of the second tube 520 is constantly in communication with the internal space 225 of the second expansion member 220. The other end of the second tube 520 is constantly in communication with the second opening 313 of the tubular member 310 of the connector section 300 (see FIGS. 8 and 12).

[0042] As shown in Figures 3, 4, 5 and 6, the second expansion member 220 can be positioned opposite the first expansion member 210 with the approximate center position c1 of the width direction of the support member 100 sandwiched therebetween.

[0043] The film-like member that constitutes the second expansion member 220 can be fixed to the inner surface 100a of the support member 100 by, for example, fusion or adhesion.

[0044] As shown in Figures 3 and 4, the second expansion member 220 can be configured to have a substantially trapezoidal shape in a plan view. The planar shape of the second expansion member 220 is not particularly limited as long as it can apply a predetermined compressive force to the puncture site p. There are also no particular limitations on the cross-sectional shape of the second expansion member 220 before and after expansion, or the position at which the second expansion member 220 is arranged in the support member 100. For example, the second expansion member 220 may have a planar shape and / or cross-sectional shape different from those of the first expansion member 210.

[0045] 3, 4, 5, 14, and 15, the second expansion member 220 has a marker part 228 for aligning the second expansion member 220 with the puncture site p. The marker part 228 can be configured, for example, by printing a predetermined shape and color on the underside of the second expansion member 220 (the surface that is placed facing the body surface of the hand H), or by attaching a sticker that forms the marker part 228.

[0046] For the same reasons as those explained above for the marker portion 218 of the first expansion member 210, the position that overlaps in a planar view with the position where the marker portion 228 is formed in the second expansion member 220, and the position that overlaps in a planar view with the position where the marker portion 228 is formed in the support member 100, can be formed to be transparent or translucent.

[0047] The material of the membrane-like members that make up the first expansion member 210 and the second expansion member 220 is not particularly limited, but examples include polyolefins such as polyvinyl chloride, polyethylene, polypropylene, polybutadiene, and ethylene-vinyl acetate copolymer (EVA), polyesters such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), various thermoplastic elastomers such as polyvinylidene chloride, silicone, polyurethane, polyamide elastomer, polyurethane elastomer, and polyester elastomer, nylon, nylon elastomer, or any combination of these (blend resins, polymer alloys, laminates, etc.).

[0048] <Connector section 300> 6 to 13 are schematic diagrams illustrating the structure of the connector section 300. Figures 6, 7, 8, and 9 are views showing an example of how the connector section 300 is operated when expanding the first expansion member 210, and Figures 10, 11, 12, and 13 are views showing an example of how the connector section 300 is operated when expanding the second expansion member 220. Note that the fluid injection member 600 is not shown in Figures 6 and 10.

[0049] As shown in Figures 5, 8, 9, 12, and 13, the connector portion 300 has a tubular member 310 having an inner cavity 311, a first valve body portion 320 located in the inner cavity 311 of the tubular member 310, and a second valve body portion 330 located in the inner cavity 311 of the tubular member 310 and arranged at a position different from the first valve body portion 320 in the extension direction of the tubular member 310.

[0050] The extending direction of the cylindrical member 310 is the vertical direction in FIGS. 8, 9, 12, and 13, and is the same as the height direction of the cylindrical member 310.

[0051] In the hemostatic device 10, the connector portion 300 is attached to the support member 100 so that the center position of the connector portion 300 in a plan view overlaps with the center position c1 of the support member 100 in the width direction.

[0052] As shown in FIGS. 3 and 4, the connector portion 300 is disposed between the first expansion member 210 and the second expansion member 220 when the support member 100 is seen in a plan view.

[0053] As shown in Figures 8, 9, 12, and 13, the tubular member 310 has a first opening 312 located between the first valve body portion 320 and the second valve body portion 330, which connects the first expansion member 210 to the inner cavity 311 of the tubular member 310, and a second opening 313 located between the second valve body portion 330 and the bottom 316 of the tubular member 310, which connects the second expansion member 220 to the inner cavity 311 of the tubular member 310.

[0054] The inner cavity 311 of the cylindrical member 310 is divided into two spaces, an upper region 311a and a lower region 311b, by a second valve body portion 330 disposed in the inner cavity 311 of the cylindrical member 310. The first opening 312 is disposed so as to communicate with the upper region 311a. The second opening 313 is disposed so as to communicate with the lower region 311b.

[0055] 8, 9, 12, and 13, the cylindrical member 310 can be configured to have, for example, a substantially trapezoidal cross-sectional shape whose cross-sectional area gradually decreases from the bottom 316 side toward the upper end side. There are no particular limitations on the cross-sectional shape of the cylindrical member 310.

[0056] As shown in FIGS. 8, 9, 12, and 13, the first valve body portion 320 is disposed at the upper end portion of the cylindrical member 310. As shown in FIGS.

[0057] The first valve body 320 has an insertion portion 321 through which a fluid injection member 600 such as a syringe can be inserted. The first valve body 320 can be configured, for example, as a check valve that is configured to be switchable from a closed state to an open state as the fluid injection member 600 is inserted through the insertion portion 321.

[0058] The second valve body 330 has an insertion portion 331 through which a fluid injection member 600 such as a syringe can be inserted. The second valve body 330 can be configured, for example, as a check valve that is configured to be switchable from a closed state to an open state as the fluid injection member 600 is inserted through the insertion portion 331.

[0059] As shown in Figures 8, 9, 12, and 13, the insertion portion 321 of the first valve body portion 320 and the insertion portion 331 of the second valve body portion 330 can be positioned so that they overlap each other in the surface direction of the connector portion 300 (the surface direction of the plan view in Figure 5).

[0060] As shown in Figures 8, 9, 12, and 13, the connector portion 300 has a stopper portion 340 that is configured to prevent the fluid injection member 600 inserted from the first valve body portion 320 into the inner cavity 311 of the tubular member 310 from passing through the second valve body portion 330.

[0061] The stopper portion 340 is inserted into the inner cavity 311 of the tubular member 310 so that a part of the stopper portion 840 is located between the first valve body portion 320 and the second valve body portion 330 in the extension direction of the tubular member 310.

[0062] As shown in FIGS. 9 and 13, the tubular member 310 has a first insertion hole 315a and a second insertion hole 315b for inserting a part of the stopper portion 340 into the inner cavity 311 of the tubular member 310.

[0063] The first insertion hole 315a and the second insertion hole 315b are arranged to face each other in the movement direction of the stopper portion 340 with the insertion portion 321 of the first valve body portion 320 sandwiched therebetween.

[0064] The stopper portion 340 is disposed so as to penetrate the cylindrical member 310 via the first insertion hole 315a and the second insertion hole 315b.

[0065] The stopper portion 340 is configured to be movable between a first position P1 (see Figures 8 and 9) that prevents the fluid injection member 600 from passing through the second valve body portion 330 and a second position P2 (see Figures 12 and 13) that allows the fluid injection member 600 to pass through the second valve body portion 330.

[0066] The stopper portion 340 is slidably held relative to the tubular member 310 via the first insertion hole 315a, the second insertion hole 315b, and the inner cavity 311. The stopper portion 340 is made up of a plate-like member having an insertion hole 343 formed at a predetermined position, through which the fluid injection member 600 can be inserted.

[0067] The stopper portion 340 can be made of, for example, a resin material or a metal material having the same degree of hardness as the support member 100. Note that the stopper portion 340 can be provided with a coating to reduce the sliding resistance that occurs between the stopper portion 340 and the cylindrical member 310 when the stopper portion 340 is moved.

[0068] As shown in FIGS. 6, 8, and 9, the insertion hole 343 of the stopper portion 340 is disposed outside the lumen 311 of the tubular member 310 when the stopper portion 340 is located at the first position P1.

[0069] When the stopper portion 340 is located at the first position P1, the portion of the stopper portion 340 where the insertion hole 343 is not formed is disposed in the inner cavity 311 of the tubular member 310.

[0070] 8 and 9, the portion of the stopper portion 340 where the insertion hole 343 is not formed prevents the fluid injection member 600 of the tubular member 310 from being inserted through the second valve body portion 330 at a position closer to the upper end of the tubular member 310 than the second valve body portion 330. Therefore, the connector portion 300 can hold the fluid injection member 600 within the upper region 311a of the lumen 311.

[0071] The surgeon can inject a fluid, such as air, into the lumen 311 of the tubular member 310 through the first opening 312 and the first tube 510 by injecting the fluid into the lumen 311 of the tubular member 310 while holding the fluid injection member 600 in the upper region 311a of the lumen 311. The first valve body 320 prevents the fluid injected into the upper region 311a of the lumen 311 of the tubular member 310 from leaking out of the tubular member 310. The second valve body 330 prevents the fluid injected into the upper region 311a of the lumen 311 from migrating to the lower region 311b of the lumen 311 of the tubular member 310. Therefore, the surgeon can properly inject the fluid injected into the upper region 311a of the lumen 311 of the tubular member 310 into the first expansion member 210.

[0072] As shown in FIGS. 10, 12, and 13, the insertion hole 343 of the stopper portion 340 is disposed in the lumen 311 of the tubular member 310 when the stopper portion 340 is in the second position P2.

[0073] When the stopper portion 340 is located at the second position P2, the insertion portion 321 of the first valve body portion 320, the insertion portion 331 of the second valve body portion 330, and the insertion hole 343 of the stopper portion 340 are positioned to overlap one another. As shown in Figures 12 and 13, the insertion hole 343 of the stopper portion 340 allows the fluid injection member 600 to be inserted through the second valve body portion 330 and positioned within the lower region 311b of the lumen 311.

[0074] With the fluid injection member 600 positioned in the lower region 311b of the lumen 311, the surgeon can inject a fluid such as air into the lumen 311 of the tubular member 310, thereby injecting the fluid into the second expansion member 220 via the second opening 313 and the second tube 520. The second valve body portion 330 prevents the fluid injected into the lower region 311b of the lumen 311 of the tubular member 310 from migrating to the upper region 311a of the lumen 311 of the tubular member 310. Therefore, the surgeon can properly inject the fluid injected into the lower region 311b of the lumen 311 of the tubular member 310 into the second expansion member 220.

[0075] 9 and 12, one longitudinal end 341 of the stopper portion 340 may be provided with a projection 347a for preventing the stopper portion 340 from being released from insertion into the first insertion hole 315a of the tubular member 310. Furthermore, the other longitudinal end 342 of the stopper portion 340 may be provided with a projection 347b for preventing the stopper portion 340 from being released from insertion into the second insertion hole 315b of the tubular member 310.

[0076] As shown in FIGS. 6 and 10, the stopper portion 340 has position marker portions 346a and 346b that indicate whether the stopper portion 340 is disposed at the first position P1 or the second position P2.

[0077] 6, the position marker portion 346a is disposed near one end portion 341 of the stopper portion 340. The position marker portion 346a has a triangular shape that tapers toward the first expansion member 210 side.

[0078] 6, when the stopper portion 340 is disposed at the first position P1, the position marker portion 346a is disposed outside the tubular member 310 together with the one end portion 341. By visually checking the position marker portion 346a, the surgeon can easily understand that the hemostatic device 10 is in a state in which it is possible to expand the first expansion member 210, that is, that the position of the fluid injection member 600 is maintained in the upper region 311a of the lumen 311 of the tubular member 310 by the stopper portion 340 (see FIGS. 8 and 9).

[0079] 10, the position marker portion 346b is disposed near the other end portion 342 of the stopper portion 340. The position marker portion 346b has a triangular shape that tapers toward the second expansion member 220 side.

[0080] 10, when the stopper portion 340 is disposed at the second position P2, the position marker portion 346b is disposed outside the tubular member 310 together with the other end portion 342. By visually checking the position marker portion 346b, the surgeon can easily determine that the hemostatic device 10 is in a state in which it is possible to expand the second expansion member 220, that is, that the fluid injection member 600 has been inserted through the insertion hole 343 of the stopper portion 340 and the insertion portion 331 of the second valve body portion 330 and is positioned in the lower region 311b of the lumen 311 of the tubular member 310 (see FIGS. 12 and 13).

[0081] Each of the position marker portions 346a, 346b can be configured, for example, by printing each of the position marker portions 346a, 346b on the stopper portion 340, or by attaching a sticker forming each of the position marker portions 346a, 346b to the stopper portion 340. There are no particular limitations on the shape, size, arrangement, etc. of each of the position marker portions 346a, 346b.

[0082] <Fixing member 400> As shown in FIGS. 1 and 2, the fixing member 400 has a first band 410 connected to the support member 100, a second band 420, and a third band 430.

[0083] One end of the first band 410, located on the support member 100 side, is connected to the outer surface 100b of the support member 100. As shown in FIG. 2, a first fixing portion 441 is arranged on the inner surface of the first band 410.

[0084] 14 and 15, when the hemostatic device 10 is worn on the patient's right hand HR, the first band 410 can be placed in the inter-finger space fb1 between the thumb and index finger of the right hand HR. Also, when the hemostatic device 10 is worn on the patient's left hand HL, the first band 410 can be placed in the inter-finger space fb2 between the thumb and index finger of the left hand HL, as shown in FIG.

[0085] One end of the second band 420, located on the support member 100 side, is connected to the outer surface 100b of the support member 100. The second band 420 extends in a direction different from the direction in which the first band 410 extends from the support member 100. As shown in FIG. 1, a second fixing portion 442 is located on the outer surface of the second band 420. As shown in FIG. 2, a third fixing portion 443 is located on the inner surface of the second band 420.

[0086] The third band 430 has one end located on the support member 100 side connected to the outer surface 100b of the support member 100. The third band 430 extends from the support member 100 in a direction different from the directions in which the first band 410 and the second band 420 extend. As shown in FIG. 1 , a fourth fixing portion 444 is disposed on the outer surface of the third band 430.

[0087] 14 and 15, when the hemostatic device 10 is worn on the patient's right hand HR, the second band 420 and the third band 430 can be arranged to wrap around the patient's right hand HR. Also, when the hemostatic device 10 is worn on the patient's left hand HL, the second band 420 and the third band 430 can be arranged to wrap around the patient's left hand HL.

[0088] A third fixing portion 443 arranged on the inner surface of the second band 420 can be connected to a fourth fixing portion 444 arranged on the outer surface of the third band 430. As shown in Figures 15 and 17, the surgeon can secure the second band 420 and the third band 430 to the patient's right hand HR or left hand HL by connecting the third fixing portion 443 and the fourth fixing portion 444 while wrapping the second band 420 and the third band 430 around the patient's right hand HR or left hand HL.

[0089] A first fixing portion 441 arranged on the inner surface of the first band 410 can be connected to a second fixing portion 442 arranged on the outer surface of the second band 420. As shown in Figures 15 and 17, the surgeon can fix the first band 410, together with the second band 420 and the third band 430, to the patient's right hand HR or left hand HL by connecting the first fixing portion 441 arranged on the inner surface of the first band 410, which is arranged in the inter-finger portion fb1 of the right hand HR or the inter-finger portion fb2 of the left hand HL, to the second fixing portion 442 arranged on the outer surface of the second band 420.

[0090] The material of each of the bands 410, 420, 430 is not particularly limited, but may be made of, for example, vinyl chloride resin, polyurethane resin, polyester resin, or the like.

[0091] Each of the fixing sites 441, 442, 443, and 444 can be configured, for example, with the male or female side of a hook-and-loop fastener. The hook-and-loop fastener referred to here is a fastener that can be attached and detached from the surface, such as Magic Tape (registered trademark) or Velcro (registered trademark). The specific structure of each of the fixing sites 441, 442, 443, and 444 is not limited as long as the bands 410, 420, and 430 can be connected to each other with the hemostatic device 10 placed on the patient's hand H, thereby fixing the support member 100 in a state where it is placed over the puncture site p.

[0092] <Example of use of hemostatic device 10> Next, an example of how the hemostatic device 10 is used will be described with reference to FIGS.

[0093] The usage examples illustrate the procedure for using the hemostatic device 10 to stop bleeding at a first puncture site p1 formed in a patient's right hand HR using a first expansion member 210, as shown in Figures 14, 15, and 16, and the procedure for using the hemostatic device 10 to stop bleeding at a second puncture site p2 formed in a patient's left hand HL using a second expansion member 220, as shown in Figures 17 and 18.

[0094] FIG. 14 shows a state in which the sheath tube 710 of the introducer 700 has been inserted into the first puncture site p1 formed in the patient's right hand HR and various procedures have been performed.

[0095] When starting to stop bleeding at the first puncture site p1, the surgeon positions the support member 100 so as to cover the first puncture site p1. The surgeon can properly position the first expansion member 210 at the first puncture site p1 by positioning the marker portion 218 at the first puncture site p1 while visually checking the position of the marker portion 218 positioned on the first expansion member 210.

[0096] As shown in FIG. 15, the surgeon fastens the first band 410, the second band 420, and the third band 430 to the patient's right hand HR.

[0097] With each band 410, 420, 430 fixed to the patient's right hand HR, the surgeon positions the stopper portion 340 at the first position P1. As shown in FIG. 16, with the stopper portion 340 positioned at the first position P1, the surgeon inserts the fluid injection member 600 into the lumen 311 of the tubular member 310. When inserting the fluid injection member 600 into the lumen 311 of the tubular member 310, the surgeon can easily determine that the stopper portion 340 is positioned at the first position P1 by visually checking the position marker portion 346a. Note that the fluid injection member 600 is not shown in FIG. 15.

[0098] With the stopper portion 340 disposed at the first position P1, the hemostatic device 10 can prevent the fluid injection member 600 from passing through the second valve body portion 330 (see FIGS. 8 and 9). Therefore, the surgeon can hold the fluid injection member 600 inserted into the lumen 311 of the tubular member 310 in the upper region 311a of the lumen 311 of the tubular member 310. With the fluid injection member 600 held in the upper region 311a of the lumen 311 of the tubular member 310, the surgeon can inject fluid into the lumen 311 of the tubular member 310 by operating the fluid injection member 600, thereby injecting fluid into the first expansion member 210 via the first opening 312 and the first tube 510. This allows the surgeon to selectively expand only the first expansion member 210.

[0099] As shown in FIG. 16, in the hemostatic device 10, when the first expansion member 210 expands, the first expansion member 210 applies a compressive force to the first puncture site p1.

[0100] When the surgeon wishes to reduce the compression force applied by the first expansion member 210 to the first puncture site p1, he or she can operate the fluid injection member 600 to discharge the fluid injected into the first expansion member 210 to the outside of the connector portion 300 via the first tube 510 and the first opening 312.

[0101] Through the above procedure, the surgeon can stop bleeding at the first puncture site p1 formed in the patient's right hand HR using the first expansion member 210.

[0102] 17 and 18, when the surgeon uses the second expansion member 220 to stop bleeding at a second puncture site p2 formed on a patient's left hand HL, the surgeon places the second expansion member 220 at the second puncture site p2. The surgeon also secures the first band 410, the second band 420, and the third band 430 to the patient's left hand HL.

[0103] The surgeon places the stopper portion 340 at the second position P2 by moving the stopper portion 340. The surgeon can easily recognize that the stopper portion 340 is placed at the second position P2 by visually checking the position marker portion 346b.

[0104] With the stopper portion 340 placed at the second position P2, the surgeon inserts the fluid injection member 600 into the lumen 311 of the tubular member 310. Note that the fluid injection member 600 is not shown in FIG.

[0105] With the stopper portion 340 positioned at the second position P2, the hemostatic device 10 allows the fluid injection member 600 to be inserted through the second valve body portion 330 (see FIGS. 12 and 13). This allows the surgeon to position the fluid injection member 600 inserted into the lumen 311 of the tubular member 310 in the lower region 311b of the lumen 311 of the tubular member 310. With the fluid injection member 600 positioned in the lower region 311b of the lumen 311 of the tubular member 310, the surgeon can inject fluid into the lumen 311 of the tubular member 310 by operating the fluid injection member 600, thereby injecting fluid into the second expansion member 220 via the second opening 313 and the second tube 520. This allows the surgeon to selectively expand only the second expansion member 220.

[0106] In the hemostatic device 10, when the second expansion member 220 expands, the second expansion member 220 applies a compressive force to the second puncture site p2.

[0107] When the surgeon wishes to reduce the compression force applied by the second expansion member 220 to the second puncture site p2, he or she can operate the fluid injection member 600 to discharge the fluid injected into the second expansion member 220 to the outside of the connector portion 300 via the second tube 520 and the second opening 313.

[0108] Through the above procedure, the surgeon can use the second expansion member 220 to stop bleeding at the second puncture site p2 formed in the patient's left hand HL.

[0109] The hemostatic device 10 includes multiple expansion members 210, 220 arranged at different positions in the width direction of the support member 100. Therefore, when stopping bleeding at a first puncture site p1 formed on the patient's right hand HR, the first expansion member 210 can be used to properly stop bleeding. Furthermore, when stopping bleeding at a second puncture site p2 formed on the patient's left hand HL, the hemostatic device 10 can properly stop bleeding using the second expansion member 220.

[0110] The hemostatic device 10 includes a single connector 300 as a mechanism for controlling the expansion and contraction of each of the expansion members 210, 220. Therefore, even when the hemostatic device 10 is used to stop bleeding at a first puncture site p1 formed on a patient's right hand HR and a second puncture site p2 formed on a patient's left hand HL, the fluid injection member 600 can be appropriately and easily connected to the single connector 300. This prevents improper connection of the fluid injection member 600 to the wrong connector. Furthermore, because the hemostatic device 10 has a structure in which only a single connector 300 is attached, the connector 300 can be prevented from accidentally touching the patient's fingers or coming into contact with surrounding objects when the hemostatic device 10 is attached to the patient's right hand HR or left hand HL.

[0111] As described above, the hemostatic device 10 according to this embodiment comprises a support member 100 configured to cover a puncture site p formed on a patient's hand H, a first expansion member 210 connected to the support member 100 and configured to be expandable by injection of a fluid, a second expansion member 220 connected to the support member 100 at a position different from the first expansion member 210 and configured to be expandable by injection of a fluid, a connector portion 300 located on the support member 100 and configured to allow fluid to be selectively injected into one of the first expansion member 210 and the second expansion member 220, and a fixing member 400 configured to fix the support member 100 to the hand H. The connector portion 300 comprises a tubular member 310 having an inner cavity 311, a first valve body portion 320 located in the inner cavity 311 of the tubular member 310, and a second valve body portion 330 located in the inner cavity 311 of the tubular member 310 and disposed at a position different from the first valve body portion 320 in the extension direction of the tubular member 310. The tubular member 310 has a first opening 312 located between the first valve body portion 320 and the second valve body portion 330, which connects the first expansion member 210 to the inner cavity 311 of the tubular member 310, and a second opening 313 located between the second valve body portion 330 and the bottom 316 of the tubular member 310, which connects the second expansion member 220 to the inner cavity 311 of the tubular member 310.

[0112] In the hemostatic device 10 configured as described above, a fluid injection member 600 for injecting a fluid is disposed between the first valve body portion 320 and the second valve body portion 330, and by injecting a fluid through the fluid injection member 600, the fluid can be injected into the first expansion member 210 through the first opening 312. In addition, in the hemostatic device 10, a fluid injection member 600 is disposed between the second valve body portion 330 and the bottom 316 of the tubular member 310, and by injecting a fluid through the fluid injection member 600, the fluid can be injected into the second expansion member 220 through the second opening 313. Therefore, the hemostatic device 10 can selectively expand one of the first expansion member 210 and the second expansion member 220 by injecting a fluid while aligning the position of the fluid injection member 600 with one of the first opening 312 and the second opening 313 in the extension direction of the tubular member 310. Therefore, the hemostatic device 10 does not need to be provided with a connector portion dedicated to expanding the first expansion member 210 and a connector portion dedicated to expanding the second expansion member 220. This prevents problems such as the surgeon incorrectly connecting the fluid injection member 600 when the hemostatic device 10 is provided with multiple connector portions, and prevents reduction in usability caused by unintentional contact of the patient's fingers or surrounding objects with the connector portions due to multiple connector portions being arranged on the support member 100. Furthermore, the hemostatic device 10 can be used on both the left and right hands H by expanding the first expansion member 210 or the second expansion member 220 with the first expansion member 210 or the second expansion member 220 selectively arranged at the first puncture site p1 formed on the right hand HR or the second puncture site p2 formed on the left hand HL. Furthermore, in the hemostatic device 10, the first opening 312 communicating with the first expansion member 210 and the second opening 313 communicating with the second expansion member 220 are arranged at different positions in the extension direction of the tubular member 310. Therefore, the hemostatic device 10 can employ a compact structure in which the connector portion 300 is not formed unnecessarily large in the extension direction of the support member 100 (the direction in which it expands in a plan view). This makes it possible to prevent the connector portion 300 of the hemostatic device 10 from being arranged so as to overlap with the expansion members 210, 220 in the planar direction.Therefore, the hemostatic device 10 can appropriately position and place the first expansion member 210 or the second expansion member 220 at each puncture site p1, p2 formed on the right hand HR or the left hand HL without being obstructed by the connector portion 300. Furthermore, by adopting the above-described compact structure for the connector portion 300, the hemostatic device 10 allows the surgeon to adjust the amount of fluid injected into the first expansion member 210 or the second expansion member 220 while visually checking the state of bleeding from the puncture site p.

[0113] The connector portion 300 also has a stopper portion 340 between the first valve body portion 320 and the second valve body portion 330, which is configured to prevent the fluid injection member 600 inserted from the first valve body portion 320 into the inner cavity 311 of the tubular member 310 from passing through the second valve body portion 330.

[0114] By including the stopper portion 340 configured as described above, the hemostatic device 10 can prevent the fluid injection member 600 inserted into the lumen 311 of the tubular member 310 from passing through the first valve body portion 320 by mistake through the second valve body portion 330. Therefore, the hemostatic device 10 can more reliably expand only one of the first expansion member 210 and the second expansion member 220.

[0115] The stopper portion 340 is inserted into the inner cavity 311 of the cylindrical member 310 so as to be located between the first valve body portion 320 and the second valve body portion 330 in the extension direction of the cylindrical member 310. The stopper portion 340 is configured to be movable between a first position P1 that prevents the fluid injection member 600 from passing through the second valve body portion 330 and a second position P2 that allows the fluid injection member 600 to pass through the second valve body portion 330.

[0116] By including the stopper portion 340 configured as described above, the hemostatic device 10 can easily switch the position of the stopper portion 340 between the first position P1 and the second position P2. By switching the position of the stopper portion 340 between the first position P1 and the second position P2, the hemostatic device 10 can more reliably expand only one of the first expansion member 210 and the second expansion member 220.

[0117] The stopper portion 340 also has position marker portions 346a, 346b that indicate whether the stopper portion 340 is positioned at the first position P1 or the second position P2.

[0118] By providing the position marker portions 346a, 346b configured as described above, the hemostatic device 10 allows the surgeon to easily visually ascertain the position of the stopper portion 340 when expanding each of the expansion members 210, 220. By visually checking the position of the stopper portion 340, the surgeon can reliably expand only the expansion member that he or she wishes to expand, either the first expansion member 210 or the second expansion member 220.

[0119] Next, a hemostatic device according to a modification of the first embodiment and a hemostatic device according to other embodiments will be described. In the description of the modification and other embodiments, the description of the components and the procedure for using the hemostatic device already described in the description of the first embodiment will be omitted as appropriate. Furthermore, in each modification and other embodiments, content not specifically described can be the same as the above-described embodiment.

[0120] (Variation 1) Fig. 19 shows a cross-sectional view of a connector portion 300 of a hemostatic device according to Modification 1. Fig. 19 is a view corresponding to Fig. 8 of the first embodiment described above.

[0121] The connector section 300 according to the first modification includes a seal member 348 that prevents fluid from leaking between the stopper section 340 and the insertion holes 315a, 315b of the cylindrical member 310 (see FIGS. 9 and 13).

[0122] As shown in FIG. 19 , the seal member 348 is fixed to the surface of the stopper portion 340. The seal member 348 can be made of, for example, a resin member. The seal member 348 comes into close contact with the inner walls of the insertion holes 315a, 315b into which the stopper portion 340 is inserted, thereby preventing fluid from leaking from the insertion holes 315a, 315b. Therefore, the hemostatic device 10 can prevent fluid injected into the upper region 311a or the lower region 311b of the lumen 311 of the tubular member 310 from leaking to the outside of the tubular member 310 through the insertion holes 315a, 315b. This allows the hemostatic device 10 to properly inject the fluid injected into the lumen 311 of the tubular member 310 into the expansion members 210, 220.

[0123] In the hemostatic device, stopper portion 340 itself may be made of a material that can adhere closely to the inner walls of insertion holes 315 a, 315 b. When stopper portion 340 is configured in this manner, stopper portion 340 can achieve the same effect as when stopper portion 340 is provided with sealing member 348.

[0124] (Variation 2) Figures 20 and 21 are cross-sectional views of a connector portion 300 of a hemostatic device according to Modification 2. Figure 20 is a view corresponding to Figure 8 of the first embodiment described above. Figure 21 is a view corresponding to Figure 12 of the first embodiment described above.

[0125] The connector portion 300 according to the second modification includes a third valve body portion 350 disposed between the first valve body portion 320 and the stopper portion 340 .

[0126] 21 , the surgeon can position the fluid injection member 600 in the lower region 311b of the lumen 311 of the tubular member 310 via the insertion portion 351 of the third valve body 350, the insertion hole 343 of the stopper body 340, and the insertion portion 331 of the second valve body 330 by inserting the fluid injection member 600 into the lumen 311 of the tubular member 310 with the stopper body 340 positioned at the second position P2.

[0127] The hemostatic device 10 includes a third valve body portion 350 disposed between the first valve body portion 320 and the stopper portion 340, and therefore can effectively prevent fluid from leaking out of the connector portion 300 through the insertion holes 315a, 315b when the stopper portion 340 inserted into each insertion hole 315a, 315b (see Figures 9 and 13) is moved between the first position P1 and the second position P2.

[0128] (Variation 3) Figures 22, 23, and 24 show a hemostatic device according to Modification 3. Figure 22 is a plan view corresponding to Figure 10 of the first embodiment described above. Figure 22 shows a state in which the stopper portion 340A is disposed at the second position P2. Figure 23 is a cross-sectional view corresponding to arrows 23A-23A shown in Figure 22, and Figure 24 is a cross-sectional view corresponding to arrows 24A-24A shown in Figure 22. Note that the fluid injection member 600 is not shown in Figure 22.

[0129] 24 , a single insertion hole 315 for inserting a stopper portion 340A is formed in a tubular member 310 included in a connector portion 300 according to Modification 3. The stopper portion 340A is configured such that, when the stopper portion 340A is arranged at the second position P2, the other end portion 342 of the stopper portion 340A is located within the inner cavity 311 of the tubular member 310. In other words, the stopper portion 340A is not arranged to pass through the connector portion 300.

[0130] The other end 342 of the stopper portion 340A is provided with a projection 347c for preventing the stopper portion 340A from coming off the insertion hole 315.

[0131] The stopper portion 340A does not have the insertion hole 343 that is provided in the stopper portion 340 of the first embodiment described above.

[0132] 23 and 24, when the stopper portion 340A is disposed at the second position P2, the other end 342 of the stopper portion 340A is retracted to a position where it does not overlap with the insertion portions 321, 331 of the valve body portions 320, 330. Therefore, when the stopper portion 340A is disposed at the second position P2, the stopper portion 340A allows the fluid injection member 600 to be inserted through the insertion portion 331 of the second valve body portion 330. Furthermore, when the stopper portion 340A is disposed at the first position P1 (not shown), the stopper portion 340A is disposed at a position where a portion of the stopper portion 340A overlaps with the insertion portion 331 of the second valve body portion 330. Therefore, the stopper portion 340A can prevent the fluid injection member 600 from passing through the insertion portion 331 of the second valve body portion 330 when the stopper portion 340A is placed at the first position P1.

[0133] As shown in FIG. 22, a position marker 346c can be provided near one end 341 of the stopper 340A to indicate that the stopper 340A is positioned at the second position P2.

[0134] (Second embodiment) 25, 26, and 27 show a connector portion 300A included in a hemostatic device according to a second embodiment. FIG. 25 is a simplified plan view of the connector portion 300A according to the second embodiment. FIG. 26 is a cross-sectional view taken along arrows 26A-26A in FIG. 25, showing a state in which a fluid injection member 600 is disposed in the upper region 311a of the lumen 311 of the tubular member 310. FIG. 27 is a cross-sectional view taken along arrows 26A-26A in FIG. 25, showing a state in which a fluid injection member 600 is disposed in the lower region 311b of the lumen 311 of the tubular member 310. Note that the fluid injection member 600 is not shown in FIG. 25.

[0135] 25, 26, and 27, a first valve body portion 320A included in the hemostatic device according to the second embodiment has a first insertion portion 321a and a second insertion portion 321b located at a different position from the first insertion portion 321a. In this embodiment, the first insertion portion 321a and the second insertion portion 321b are arranged at a predetermined distance in a direction perpendicular to the width direction of the support member 100 (the vertical direction in FIG. 25).

[0136] As shown in Figures 26 and 27, the second valve body portion 330A has a first region 335a through which the fluid injection member 600 can be inserted, and a second region 335b made of a material harder than the first region 335a and configured to prevent the fluid injection member 600 inserted from the first valve body portion 320A from being inserted into the second valve body portion 330A.

[0137] The second region 335b of the second valve body portion 330A does not have an insertion portion formed therein that allows the fluid injection member 600 to be inserted through the second valve body portion 330A.

[0138] As shown in FIG. 25, the connector portion 300A is configured such that when the first valve body portion 320A is projected onto the second valve body portion 330A, the first insertion portion 321a is located in the second region 335b and the second insertion portion 321b is located in the first region 335a.

[0139] As shown in Fig. 26, the hemostatic device according to the second embodiment can prevent a fluid injection member 600 inserted through the first insertion portion 321a of the first valve body portion 320A and into the lumen 311 of the tubular member 310 from passing through the second region 335b, which is made of a harder material than the first region 335a. In other words, the second region 335b of the second valve body portion 330A functions as a stopper that prevents the fluid injection member 600 inserted through the first insertion portion 321a from moving to the lower region 311b. Furthermore, as shown in Fig. 27, the hemostatic device according to the second embodiment allows a fluid injection member 600 inserted through the second insertion portion 321b of the first valve body portion 320A and into the lumen 311 of the tubular member 310 to pass through the insertion portion 331 of the first region 335a. Therefore, the hemostatic device of the second embodiment can selectively expand the first expansion member 210 and the second expansion member 220, similar to the hemostatic device 10 of the first embodiment described above, by inserting a fluid injection member 600 into either the first insertion portion 321a of the first valve body portion 320A or the second insertion portion 321b of the first valve body portion 320A.

[0140] As shown in Figures 26 and 27, the connector portion 300A is disposed in the inner cavity 311 of the tubular member 310 and has a partition portion 360 that prevents the fluid injection member 600 inserted from the first insertion portion 321a into the inner cavity 311 of the tubular member 310 from moving into the first region 335a.

[0141] The partition portion 360 can be made of, for example, a material having the same hardness as the second region 335b. As shown in Figures 26 and 27, the partition portion 360 can be disposed so as to extend substantially perpendicularly between the first valve body portion 320A and the second valve body portion 330A.

[0142] In the hemostatic device according to the second embodiment, the connector portion 300A is provided with the partition portion 360, and therefore the fluid injection member 600 inserted into the lumen 311 of the tubular member 310 from the first insertion portion 321a can be prevented from accidentally moving into the first region 335a. Therefore, the surgeon can selectively expand the first expansion member 210 using the fluid injection member 600 inserted into the lumen 311 of the tubular member 310 from the first insertion portion 321a, while preventing the second expansion member 220 from being accidentally expanded.

[0143] 25, a position marker 346a can be arranged near the first insertion portion 321a of the first valve body 320A, indicating that the first expansion member 210 can be selectively expanded by inserting the fluid injection member 600 into the first insertion portion 321a. Furthermore, a position marker 346b can be arranged near the second insertion portion 321b of the first valve body 320A, indicating that the second expansion member 220 can be selectively expanded by inserting the fluid injection member 600 into the second insertion portion 321b.

[0144] (Third embodiment) 28 to 36 show a connector portion 800 provided in a hemostatic device according to the third embodiment. In this embodiment, structures other than the connector portion 800 provided in the hemostatic device (support member, first expansion member, second expansion member, fixing member, etc.) are not shown. Note that the structures other than the connector portion 800 can be configured substantially the same as those of the hemostatic device 10 according to the first embodiment described above.

[0145] Figure 28 shows a partial cross-sectional view of the connector portion 800, Figure 29 shows the connector portion 800 as seen from the arrow 29A shown in Figure 28, and Figure 30 shows a cross-sectional view of the connector portion 800 along the arrows 30A-30A shown in Figure 29. Figure 31 shows a partial cross-sectional view of the connector portion 800 with the fluid injection member 600A inserted, Figure 32 shows the connector portion 800 as seen from the arrow 32A shown in Figure 31, and Figure 33 shows a cross-sectional view of the connector portion 800 along the arrows 33A-33A shown in Figure 32. Figure 34 shows a partial cross-sectional view of the connector portion 800 with the fluid injection member 600A inserted, Figure 35 shows the connector portion 800 as seen from the arrow 35A shown in Figure 34, and Figure 36 shows a cross-sectional view of the connector portion 800 along the arrows 36A-36A shown in Figure 35. 28 to 33 show a state in which the stopper portion 840 is located at the second position P2, and FIGS. 34 to 36 show a state in which the stopper portion 840 is located at the first position P1.

[0146] As shown in Figures 28, 29, 31, 32, 34, and 35, the hemostatic device of the third embodiment comprises a support member 100 configured to cover the puncture site p, a first expansion member 210 connected to the support member 100 and configured to be expandable by injection of a fluid, a second expansion member 220 connected to the support member 100 at a position different from the first expansion member 210 and configured to be expandable by injection of a fluid, a connector portion 800 configured to selectively inject a fluid into one of the first expansion member 210 and the second expansion member 220, and a fixing member 400 configured to fix the support member 100 to the hand H (see Figures 1 to 5 for the support member 100, first expansion member 210, second expansion member 220, and fixing member 400).

[0147] The connector portion 800 comprises a first member 810 having an inner cavity 811, a second member 820 located in the inner cavity 811 of the first member 810 and configured to be connectable to the fluid injection member 600A, an elastic member 830 located between the first member 810 and the second member 820, and a stopper portion 840 located on the outer surface of the first member 810.

[0148] 28 and 29, first member 810 is configured as a tubular member whose upper end is open to the outside. Second member 820 is disposed in inner cavity 811 of first member 810 with a portion of second member 820 exposed from the upper end of first member 810. Second member 820 is supported by elastic member 830 disposed between the bottom surface of second member 820 and the inner surface of the bottom of first member 810. Elastic member 830 can be configured as, for example, a known spring member.

[0149] As shown in Figures 28 and 29, the first member 810 has a first opening 812 that connects the first expansion member 210 to the inner cavity 811 of the first member 810, and a second opening 813 that is located at a position different from the first opening 812 in the extension direction of the first member 810 (the up and down direction in Figures 28 and 29) and connects the second expansion member 220 to the inner cavity 811 of the first member 810.

[0150] 28 and 29, the second member 820 has a hole 821 configured to be selectively alignable with either the first opening 812 or the second opening 813. Furthermore, as shown in FIGS. 31 and 32, the second member 820 has a base-end opening 824 into which the front tube portion 611 of the fluid injection member 600A can be inserted and connected, and a flow path 822 extending between the base-end opening 824 and the hole 821. The flow path 822 has a step 823 formed therein, against which the distal end surface of the front tube portion 611 abuts when the front tube portion 611 of the fluid injection member 600A is inserted into the base-end opening 824.

[0151] As shown in Figures 28, 29, 31, 32, 34, and 35, the stopper portion 840 is configured to be movable between a first position P1 and a second position P2 that protrudes beyond the base end surface (upper end surface) 810a of the first member 810.

[0152] As shown in FIGS. 34 and 35, when the stopper portion 840 of the connector portion 800 is located at the first position P1, the hole portion 821 and the second opening portion 813 can be aligned in the extension direction of the first member 810.

[0153] As shown in Figures 31 and 32, when the stopper portion 840 of the connector portion 800 is positioned at the second position P2, the hole portion 821 and the second opening 813 cannot be aligned in the extension direction of the first member 810, but the hole portion 821 and the first opening 812 can be aligned in the extension direction of the first member 810.

[0154] The stopper portion 840 has a main body portion 841 extending in the extension direction of the first member 810, and a ring portion 842 arranged at the lower end of the main body portion 841. The ring portion 842 is arranged along the circumferential direction of the outer surface of the first member 810. When the stopper portion 840 is arranged on the outer surface of the first member 810, it is configured to be movable in the extension direction of the first member 810.

[0155] As shown in FIGS. 32, 33, 35, and 36, the connector section 800 has a locking section 850 that can hold the stopper section 840 at the first position P1 and the second position P2.

[0156] The locking portion 850 has a first groove portion 815 formed on the outer surface of the first member 810 and extending along the extension direction of the first member 810, second groove portions 816a, 816b formed on the outer surface of the first member 810 and extending along the circumferential direction of the first member 810, and a protrusion 843 formed on the inner surface of the stopper portion 840 and configured to be movable along the first groove portion 815 and the second groove portions 816a, 816b.

[0157] 29 and 30 , when the convex portion 843 is positioned in the first groove portion 815, the stopper portion 840 can move along the extension direction of the first member 810. However, when the convex portion 843 is positioned in the first groove portion 815, the rotation of the stopper portion 840 along the circumferential direction of the first member 810 is restricted. Therefore, when the convex portion 843 is positioned in the first groove portion 815, the stopper portion 840 can move only in the extension direction of the first member 810.

[0158] 35 and 36 , when the convex portion 843 is positioned in the second groove portion 816a, the stopper portion 840 is movable along the circumferential direction of the first member 810. However, when the convex portion 843 is positioned in the second groove portion 816a, the movement of the stopper portion 840 along the extension direction of the first member 810 is restricted. In other words, when the convex portion 843 is positioned in the second groove portion 816a, the position of the stopper portion 840 in the extension direction of the first member 810 is fixed.

[0159] 32 and 33, when the convex portion 843 is positioned in the second groove portion 816b, the stopper portion 840 is movable along the circumferential direction of the first member 810. However, when the convex portion 843 is positioned in the second groove portion 816b, the movement of the stopper portion 840 along the extension direction of the first member 810 is restricted. In other words, when the convex portion 843 is positioned in the second groove portion 816b, the position of the stopper portion 840 in the extension direction of the first member 810 is fixed.

[0160] An example of the operation of the connector section 800 will now be described.

[0161] 28 and 29 show a state in which the fluid injection member 600A is not connected to the second member 820. In this state, the stopper portion 840 is held in a state in which the base end surface 840a of the stopper portion 840 protrudes further than the base end surface 810a of the first member 810.

[0162] As shown in FIGS. 31 and 32 , when aligning the hole 821 with the first opening 812, the surgeon places the stopper portion 840 at the second position P2. The surgeon can place the stopper portion 840 at the second position P2 by pressing the stopper portion 840 down relative to the first member 810. The surgeon can hold the stopper portion 840 at the second position P2 by using the locking portion 850. With the stopper portion 840 held at the second position P2, the surgeon connects the fluid injection member 600A to the proximal opening 824 of the second member 820. Note that in this embodiment, a dedicated fluid injection member having a front tube portion 611 that can be inserted into and connected to the proximal opening 824 and a large-diameter portion 612 located on the proximal side of the front tube portion 611 can be used as the fluid injection member 600A.

[0163] The surgeon inserts the fluid injection member 600A into the second member 820 until the tip surface of the front tube portion 611 of the fluid injection member 600A abuts against the stepped portion 823 of the second member 820. By pressing down the fluid injection member 600A with the tip surface of the front tube portion 611 of the fluid injection member 600A abutting against the stepped portion 823 of the second member 820, the surgeon can lower the second member 820 to a position where the large diameter portion 612 of the fluid injection member 600A abuts against the base end surface 840a of the stopper portion 840. The surgeon can align the hole 821 with the first opening 812 by moving the second member 820 to a position where the large diameter portion 612 of the fluid injection member 600A abuts against the base end surface 840a of the stopper portion 840. The surgeon can selectively expand the first expansion member 210 that is communicated with the first opening 812 by operating the fluid injection member 600A to inject fluid while aligning the hole 821 with the first opening 812. Note that, as shown in Figures 31 and 32, when the stopper portion 840 is placed at the second position P2, the stopper portion 840 is held in a state in which the base end surface 840a of the stopper portion 840 protrudes further than the base end surface 810a of the first member 810.

[0164] As shown in FIGS. 34 and 35 , when aligning the hole 821 and the second opening 813, the surgeon places the stopper portion 840 at the first position P1. The surgeon can place the stopper portion 840 at the first position P1 by pressing the stopper portion 840 down relative to the first member 810. The surgeon can hold the stopper portion 840 at the first position P1 by using the locking portion 850. With the stopper portion 840 held at the first position P1, the surgeon can lower the second member 820 to a position where the large diameter portion 612 of the fluid injection member 600A abuts against the base end surface 810a of the first member 810 by pressing down the fluid injection member 600A inserted into and connected to the base end opening 824 of the second member 820. The surgeon can align the hole 821 with the second opening 813 by moving the second member 820 to a position where the large diameter portion 612 of the fluid injection member 600A abuts against the base end surface 810a of the first member 810. With the hole 821 aligned with the second opening 813, the surgeon can selectively expand the second expansion member 220 communicated with the second opening 813 by operating the fluid injection member 600A to inject fluid. Note that, as shown in FIGS. 34 and 35 , when the stopper portion 840 is arranged at the first position P1, the stopper portion 840 is maintained in a state where the base end surface 840a of the stopper portion 840 does not protrude from the base end surface 810a of the first member 810.

[0165] Note that the stopper portion 840 may be configured such that, when held at the first position P1, the fluid injection member 600A inserted into and connected to the proximal end opening 824 of the second member 820 is pushed down, thereby aligning the hole 821 with the second opening 813. Therefore, the stopper portion 840 may be configured such that, when placed at the first position P1, the proximal end surface 840a of the stopper portion 840 is held in a state in which it protrudes beyond the proximal end surface 810a of the first member 810. In this case, the amount by which the proximal end surface 840a of the stopper portion 840 protrudes from the proximal end surface 810a of the first member 810 when the stopper portion 840 is held at the first position P1 is smaller than the amount by which the proximal end surface 840a of the stopper portion 840 protrudes from the proximal end surface 810a of the first member 810 when the stopper portion 840 is held at the second position P2.

[0166] As described above, the hemostatic device 10 of this embodiment comprises a support member 100 configured to cover a puncture site p formed in a patient's hand H, a first expansion member 210 connected to the support member 100 and configured to be expandable by injecting a fluid, a second expansion member 220 connected to the support member 100 at a position different from the first expansion member 210 and configured to be expandable by injecting a fluid, a connector portion 800 located on the support member 100 and configured to be able to selectively inject a fluid into one of the first expansion member 210 and the second expansion member 220, and a fixing member 400 configured to fix the support member 100 to the hand H. The connector portion 800 includes a first member 810 having an inner cavity 811, a second member 820 located in the inner cavity 811 of the first member 810 and configured to be connectable to the fluid injection member 600A, an elastic member 830 located between the first member 810 and the second member 820, and a stopper portion 840 located on the outer surface of the first member 810. The first member 810 has a first opening 812 that connects the first expansion member 210 to the inner cavity 811 of the first member 810, and a second opening 813 that is located at a position different from the first opening 812 in the extension direction of the first member 810 and connects the second expansion member 220 to the inner cavity 811 of the first member 810. The second member 820 has a hole portion 821 configured to be selectively alignable with one of the first opening 812 and the second opening 813. The stopper portion 840 is configured to be movable between a first position P1 and a second position P2 that protrudes further than the base end surface 810a of the first member 810, and when the stopper portion 840 is positioned at the first position P1, the hole portion 821 and the second opening 813 can be aligned in the extension direction of the first member 810, and when the stopper portion 840 is positioned at the second position P2, the hole portion 821 and the second opening 813 cannot be aligned in the extension direction of the first member 810, but the hole portion 821 and the first opening 812 can be aligned in the extension direction of the first member 810.

[0167] The hemostatic device according to the third embodiment can selectively expand one of the first expansion member 210 and the second expansion member 220 by selectively aligning the hole 821 with the first opening 812 or the second opening 813. Therefore, the hemostatic device described above can prevent problems such as an operator incorrectly connecting the fluid injection member 600A when the hemostatic device is provided with multiple connectors, and can prevent reduced usability caused by unintentional contact of the patient's fingers or surrounding objects with the connectors due to multiple connectors being arranged on the support member 100. Furthermore, the hemostatic device described above can be used on both the left and right hands H by expanding the first expansion member 210 or the second expansion member 220 while the first expansion member 210 or the second expansion member 220 is selectively arranged at the first puncture site p1 formed on the right hand HR or the second puncture site p2 formed on the left hand HL. Furthermore, in the hemostatic device described above, the first opening 812 communicating with the first expansion member 210 and the second opening 813 communicating with the second expansion member 220 are arranged at different positions in the extension direction of the first member 810. Therefore, the hemostatic device described above can employ a compact structure in which the connector portion 800 is not formed unnecessarily large in the extension direction of the support member 100 (the direction in which it expands in a planar view). This prevents the connector portion 800 from being arranged so that it overlaps with each of the expansion members 210, 220 in the planar direction. Therefore, the hemostatic device described above can appropriately position and arrange the first expansion member 210 or the second expansion member 220 at each of the puncture sites p1, p2 formed on the right hand HR or the left hand HL without being obstructed by the connector portion 800. In addition, by employing the above-described compact structure for the connector portion 800, the hemostatic device allows the surgeon to adjust the amount of fluid injected into the first expansion member 210 or the second expansion member 220 while visually checking the bleeding condition from the puncture site p. Furthermore, the hemostatic device can reliably align the hole portion 821 with each of the openings 812, 813 by positioning the stopper portion 840 at the first position P1 or the second position P2.Therefore, the hemostatic device described above can expand only one of the first expansion member 210 and the second expansion member 220 more reliably.

[0168] Furthermore, in the above-described hemostatic device, connector portion 800 has a locking portion 850 that can hold stopper portion 840 at first position P1 and second position P2. Locking portion 850 has a first groove portion 815 formed on the outer surface of first member 810 and extending along the extension direction of first member 810, second groove portions 816a, 816b formed on the outer surface of first member 810 and extending along the circumferential direction of first member 810, and a protrusion 843 formed on the inner surface of stopper portion 840 and configured to be movable along first groove portion 815 and second groove portions 816a, 816b.

[0169] The hemostatic device configured as described above can maintain the position of the stopper portion 840 at the first position P1 or the second position P2 by including the lock portion 850. This allows the surgeon to more reliably expand only one of the first expansion member 210 and the second expansion member 220.

[0170] The hemostatic device of the present invention has been described above through multiple embodiments and multiple modified examples, but the present invention is not limited to the content described in the specification and can be modified as appropriate based on the description of the claims.
