Abstract

Provided is a hemostatic device (110) that can effectively apply a compression force against a puncture site (p1-p4) even when the puncture site (p1-p4) formed at a prescribed position avoiding the index finger metacarpal bone (B1) and the thumb metacarpal bone (B2) of the hand (H) is hemostatic. The hemostatic device (100) has a support member (110) configured to cover a first puncture site (p1), a fixing member (120) configured to fix the support member (110) to the first puncture site (p1), and an expansion member (180) connected to the support member (110) and configured to compress the first puncture site (p1), the rigidity of the support member (110) being greater than the rigidity of the expansion member (180). The width (W) of the support member (110) narrows from an upper end portion (111) toward a lower end portion (112). The thickness of a side surface portion (113) of the support member (110) thins from the upper end portion (111) toward the lower end portion (112).

Description

Technical Field

[0001] This invention relates to hemostatic devices. Background Technology

[0002] As a type of catheter-based surgery, the following procedures are known: various medical long instruments are inserted into blood vessels through a puncture site formed by puncturing a blood vessel in the patient's arm or hand to treat and manage lesions. For example, Patent Document 1 discloses a hemostatic device that stops bleeding at a puncture site formed to reach blood vessels (including the distal radial artery) traveling in the hand.

[0003] Patent Document 1 discloses a hemostatic device comprising: a pressing member that applies pressure to a puncture site (hereinafter sometimes referred to simply as "puncture site") formed on the patient's hand; a band for securing the pressing member to the patient's hand; and a support member disposed on the band and pressing the pressing member against the patient's hand. Furthermore, the band comprises a first band disposed between the patient's fingers and a second band wrapped around the forearm side of the patient's hand.

[0004] Existing technical documents

[0005] Patent documents

[0006] Patent Document 1: U.S. Patent Application Publication No. 2019 / 0133602 Summary of the Invention

[0007] When surgeons (hereinafter referred to as "surgeons") create puncture sites on the hand, they will position the puncture site in a predetermined location that avoids the metacarpal bones of the index finger and thumb. By setting the puncture site in such a predetermined location, surgeons can prevent indwelling needles and other puncture instruments from interfering with the metacarpal bones of each finger when creating the puncture site.

[0008] However, if the hemostatic device described in Patent Document 1 is used to stop bleeding when the puncture site is formed in a manner that avoids the specified locations of the metacarpal bones of the index finger and thumb, the following problems will arise.

[0009] When a surgeon applies hemostasis to a puncture site, the pressing and supporting components of the hemostatic device of Patent Document 1 are positioned to overlap the puncture site. When the surgeon places the hemostatic device of Patent Document 1 onto the patient's hand, the supporting component is sometimes placed on the metacarpal bones of the index finger and thumb. If the second band of the hemostatic device of Patent Document 1 is wrapped around the patient's hand with the supporting component positioned as described above, a gap will appear between the pressing component and the hand, and the second band cannot align with the circumference of the patient's hand. In this situation, by forcefully tightening the first band of the hemostatic device of Patent Document 1, the pressing and supporting components can be firmly fixed to the patient's hand. On the other hand, in this case, because the first band of the hemostatic device of Patent Document 1 needs to be forcefully tightened, the patient may sometimes experience pain. Therefore, in the hemostatic device of Patent Document 1, when the first band cannot be forcibly tightened due to the patient's pain, the support member is positioned at an angle from the fingertip side of the hand toward the forearm side, approaching the surface of the hand. If the support member of the hemostatic device of Patent Document 1 is positioned as described above, the pressing member cannot apply pressure in the vertical direction relative to the puncture site. Thus, the hemostatic device of Patent Document 1 cannot effectively apply pressure relative to the puncture site.

[0010] In view of the above-mentioned problems, the present invention aims to provide a hemostatic device that can effectively apply pressure to the puncture site even when hemostasis is performed on a puncture site formed at a predetermined location that avoids the metacarpal bones of the index finger and thumb of the hand.

[0011] The hemostatic device of the present invention comprises: a support member configured to cover a puncture site formed on a patient; a fixing member configured to fix the support member to the puncture site of the patient; and a pressing member connected to the support member and configured to compress the puncture site of the patient. The support member has an upper end, a lower end, and a side portion and has greater rigidity than the pressing member. The upper end is located at the front end of the pressing member and forms the end of the support member, while the lower end is located at the base end of the pressing member and forms a portion corresponding to the upper end. At the opposite end, the side portion connects the upper end and the lower end. The fixing member is configured to be disposed between the patient's fingers and has a first band portion extending in a first direction and a second band portion extending in a second direction different from the first direction. The support member is configured such that the width of the support member narrows from the upper end to the lower end, and the thickness of the side portion thins from the upper end to the lower end. The first band portion extends from the upper end side in the first direction, and the second band portion extends from the side portion side in the second direction.

[0012] Invention Effects

[0013] The aforementioned hemostatic device includes a support member that has greater rigidity than the pressing member. When applying hemostasis to a puncture site formed at a predetermined location avoiding the metacarpal bones of the index finger and thumb of the patient's hand, the support member is positioned to cover the puncture site together with the pressing member. By pressing the pressing member against the patient's hand, the support member prevents the pressing member from lifting off the patient's hand. Furthermore, the width of the support member narrows from the upper end to the lower end. Therefore, when the support member is positioned on the patient's hand, it can be aligned with the metacarpal bones of the index finger and thumb. Thus, the aforementioned hemostatic device can securely wrap the second band portion around the circumference of the patient's hand. Additionally, the thickness of the side portion of the support member thins from the upper end to the lower end. Moreover, the first band portion, configured to be positioned between the patient's fingers, extends from the upper end of the support member, pressing the upper end of the support member against the patient's hand. Therefore, when hemostasis is initiated with the hemostatic device worn on the patient's hand, the compression component applies force to one end of the support component. The support component is lifted at one end by the force applied by the compression component. This causes the lower surface of the support component to be positioned approximately parallel to the surface of the patient's hand. Thus, with the compression component and support component positioned at the puncture site, the first and second band portions of the hemostatic device are fixed to the patient's hand, thereby applying pressure from the compression component in the vertical direction relative to the puncture site. Consequently, the hemostatic device can effectively apply pressure relative to the puncture site. Attached Figure Description

[0038] The following is a reference to the added appendix. Figure 1 The embodiments of the present invention will be described below. The following description is not intended to limit the scope of the technology or the meaning of the terms used. Additionally, sometimes the dimensions of the accompanying drawings may be exaggerated for ease of explanation, differing from the actual scale.

[0039] <First Embodiment>

[0040] Figures 1 to 9 This is a diagram illustrating the hemostatic device 100 of this embodiment. Figures 10 to 17 This is a diagram illustrating the usage and effects of the hemostatic device 100.

[0041] like Figure 10 , Figures 13 to 17 As shown, the hemostatic device 100 can be used to stop bleeding at the puncture site when the sheath of the guide 300, which is placed at the hand H located distal to the patient's forearm A (i.e., the puncture sites p1, p2, p3, p4 described later), is pulled out.

[0042] The specific location of the puncture site that becomes the target of hemostasis of the hemostatic device 100 is not particularly limited, but in this embodiment, the following are examples: the first puncture site p1, the second puncture site p2, the third puncture site p3, and the fourth puncture site p4.

[0043] like Figure 10 , Figure 13 , Figure 14 As shown, the first puncture site p1 is formed at the distal radial artery (hereinafter also referred to as "vessel V1"), which is located distal to the nasal cavity on the dorsal side of the right hand H1 (hand H) compared to the patient's forearm A. Furthermore, the first puncture site p1 is located between the index finger metacarpal B1 and the thumb metacarpal B2, in a predetermined position that avoids the index finger metacarpal B1 and the thumb metacarpal B2. Additionally, the nasal cavity is the cavity of the hand near the radius when the patient extends the thumb of hand H.

[0044] like Figure 10 , Figure 15 As shown, the second puncture site p2 is formed at the artery V2 of the palmar artery, which runs along the dorsal side of the right hand (H1), located in the snuffbox. Compared to the first puncture site p1, the second puncture site p2 is located on the A side of the patient's forearm, and is situated between the extensor digitorum longus tendon T1 and the extensor digitorum brevis tendon T2 on the dorsal side of the patient's right hand (H1). Furthermore, the second puncture site p2 is located at a predetermined position that avoids the positions of the metacarpal bones B1 of the index finger and B2 of the thumb.

[0045] like Figure 16 As shown, the third puncture site p3 is formed in the patient's left hand H2 (hand H) at the position corresponding to the first puncture site p1 listed in the patient's right hand H1.

[0046] like Figure 17 As shown, the fourth puncture site p4 is formed in the patient's left hand H2 (hand H) at the position corresponding to the second puncture site p2 listed in the patient's right hand H1.

[0047] In the instructions, the first puncture site p1 formed on the patient's right H1 is simply referred to as "first puncture site p1", and the second puncture site p2 formed on the patient's right H1 is also simply referred to as "second puncture site p2". Similarly, the third puncture site p3 formed on the patient's left H2 is simply referred to as "third puncture site p3", and the fourth puncture site p4 formed on the patient's left H2 is also simply referred to as "fourth puncture site p4".

[0048] The following is a detailed description of hemostatic instruments 100.

[0049] <Hemostatic Instruments>

[0050] If we briefly describe 100 hemostatic devices, then as follows: Figure 1 , Figure 2 , Figure 13 , Figure 14 As shown, it includes: a support member 110 configured to cover the first puncture site p1; a fixing member 120 configured to fix the support member 110 to the first puncture site p1; and a pressing member 180 connected to the support member 110 and configured to press the first puncture site. Furthermore, the phrase "connected to the support member 110" includes the meaning that the pressing member 180 is indirectly connected to the support member 110. For example, as... Figure 1 , Figure 5 , Figure 6 As shown, the pressing member 180 (expansion member 180) is connected to the support member 110 via the connecting member 190, which is included in the above-mentioned "connection to the support member 110".

[0051] <Pressing component>

[0052] like Figure 6 As shown, the pressing member 180 can be constructed, for example, by an expansion member such as an airbag having an inner cavity 183 into which fluids such as air can flow. In this embodiment, an example of a pressing member 180 constructed by an expansion member will be described in the following description.

[0053] The expansion member 180 is, for example, a single sheet of membrane formed in a bag-like shape with an inner cavity 183. However, the expansion member 180 may also be formed by joining the edges of two sheet-like membrane materials with an inner cavity 183 formed between them in a generally rectangular shape.

[0054] The expansion member 180 expands by supplying fluid such as air into the inner cavity 183, and contracts by discharging the fluid supplied to the inner cavity 183. Figure 6 The image shows a cross-sectional view of the expansion member 180 as fluid is supplied to it, causing the expansion member 180 to expand.

[0055] The membrane material constituting the expansion member 180 can be, for example, a resin material having a specified thickness. A tube 203 (described later) is connected to the inner cavity 183 of the expansion member 180. Figure 1 , Figure 2 ).

[0056] The material of the membrane component constituting the expansion component 180 is not particularly limited, but for example, polyolefins such as polyvinyl chloride, polyethylene, polypropylene, polybutadiene, ethylene-vinyl acetate copolymer (EVA), polyesters such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), polyvinylidene chloride, polysiloxane, polyurethane, polyamide elastomer, polyurethane elastomer, polyester elastomer, nylon, nylon elastomer, or materials formed by any combination of them (mixed resin, polymer alloy, laminate, etc.).

[0057] like Figure 6 As shown, the expansion member 180 is disposed on the inner surface 130a side of the cover portion 130 of the fixing member 120.

[0058] The inner surface 130a of the covering 130 is the surface positioned on the body surface side of the patient's right hand H1 when the hemostatic device 100 is worn on the patient's right hand H1 (see reference). Figure 14 Furthermore, the outer surface 130b of the cover 130 is the surface located on the opposite side of the inner surface 130a.

[0059] like Figure 6As shown, a connecting member 190 is disposed on the inner surface 130a of the cover portion 130. The expansion member 180 can be connected to the support member 110 via the connecting member 190. The outer periphery of the expansion member 180 can be connected to the connecting member 190, for example, by adhesive and welding.

[0060] The connecting member 190 is arranged such that a space 191 is formed between it and the cover 130. A support member 110 is disposed in the space 191.

[0061] The connecting member 190 may be made of resin, for example. The outer periphery of the connecting member 190 may be connected to the cover 130 by adhesive and welding, for example.

[0062] Expansion component 180 in Figures 1 to 5 The shape shown is circular when viewed from above. However, the shape of the expansion member 180 when viewed from above is not limited to a circle. Furthermore, there are no particular limitations on the cross-sectional shape of the expansion member 180 before and after expansion, or on the specific construction of the expansion member 180.

[0063] like Figure 6 , Figure 13 , Figure 14 As shown, a marking portion 185 is provided on the expansion member 180 for aligning the expansion member 180 with the first puncture site p1.

[0064] like Figure 6 As shown, the marking portion 185 is disposed on the outer surface of the expansion member 180. Alternatively, the marking portion 185 may also be disposed on the inner surface facing the inner cavity 183 of the expansion member 180.

[0065] The marking portion 185 can be formed, for example, by a rectangular mark that is entirely colored. Furthermore, the specific shape, color, forming method, and position of the marking portion 185 on the expansion member 180 are not particularly limited. For example, the marking portion 185 may also consist of a transparent central portion and a colored linear frame surrounding that central portion.

[0066] <Supporting Components>

[0067] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the support member 110 has: an upper end portion 111 located at the front end side of the expansion member 180 and forming the end of the support member 110; a lower end portion 112 located at the base end side of the expansion member 180 and forming the end opposite to the upper end portion 111; and a side portion 113 connecting the upper end portion 111 and the lower end portion 112.

[0068] "The front end side of the expansion member 180" means the end side of the expansion member 180 located on the fingertip side when the hemostatic device 100 is fitted onto the patient's right hand H1. Figure 5 as well as Figure 13 (The upper side). Additionally, "the base side of the expansion member 180" means the end side of the expansion member 180 positioned on the patient's forearm A side when the hemostatic device 100 is fitted onto the patient's right hand H1. Figure 5 as well as Figure 13 (the lower side).

[0069] like Figure 8 As shown, the support member 110 is configured such that the width W of the support member 110 narrows from the upper end 111 toward the lower end 112.

[0070] In addition, such as Figure 9 As shown, the support member 110 is configured such that the thickness of the side portion 113 decreases from the upper end 111 towards the lower end 112. That is, the support member 110 in... Figure 6 The sectional view shown and Figure 9 In the cross-sectional view shown, the upper surface 110b slopes from the upper end 111 toward the lower end 112 toward the lower surface 110a.

[0071] Furthermore, the lower surface 110a is the side where the expansion member 180 is disposed, and the upper surface 110b is the side where the cover portion 130 is disposed.

[0072] like Figure 5 As shown, the support member 110 has a shape that is symmetrical about left and right with respect to the major axis (axis along the extension direction) C of the first belt body portion 140. Specifically, as Figure 8 As shown, the support member 110 has a generally triangular planar shape. The corners 115a, 115b, and 115c of the support member 110 located on the outer peripheral side have rounded shapes.

[0073] like Figure 7 As shown, the support member 110 has a hole 117 through which the support member 110 passes along its thickness direction. Figure 6 As shown, the hole 117 can be positioned to overlap with the expansion member 180. In this embodiment, the hole 117 is positioned to overlap with the marking portion 185 disposed on the expansion member 180.

[0074] In the hemostatic device 100, the portion of the dilator 180 with the marking portion 185, the portion of the connecting member 190 overlapping the marking portion 185, and the portion of the covering portion 130 overlapping the marking portion 185 can be made transparent. With the components 130, 180, and 190 configured in this way, the surgeon can... Figures 11 to 13When the hemostatic device 100 is fitted onto the patient's right hand H1 as shown, the transparent portions formed by the hole 117 through the support member 110 and the various components 130, 180, and 190 allow for easy visual confirmation of the position of the marking portion 185 on the dilation member 180 and / or the first puncture site p1. Furthermore, the term "transparent" includes colored transparent, colorless transparent, and translucent.

[0075] The support member 110 can be constructed from a component having greater rigidity than the expansion member 180. With this configuration, the support member 110 will... Figure 14 When the dilation member 180 is applied with pressure relative to the first puncture site p1, the support member 110 can press the dilation member 180 against the patient's right hand H1. This prevents the dilation member 180 from floating off the patient's right hand H1.

[0076] When the expansion member 180 is made of the aforementioned materials, the supporting member 110 can be made of materials such as acrylic resin, polyvinyl chloride (especially rigid polyvinyl chloride), polyethylene, polypropylene, polyolefins 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), etc.

[0077] <Fixed components>

[0078] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 13 As shown, the fixing member 120 has a cover portion 130, a first belt body portion 140, a second belt body portion 150 and a third belt body portion 160.

[0079] The cover portion 130 constitutes the main body for connecting the various belt portions 140, 150, and 160. For example... Figure 5 as well as Figure 6 As shown, a support member 110, an expansion member 180, and a connecting member 190 are disposed on the cover portion 130.

[0080] Furthermore, the fixing member 120 may be integrally formed with the cover portion 130 and each of the belt portions 140, 150, and 160, or the components constituting each of the belt portions 140, 150, and 160 may be connected to the component constituting the cover portion 130. Alternatively, the fixing member 120 may not have a cover portion 130, and each of the belt portions 140, 150, and 160 may be directly connected to the support member 110.

[0081] The first band body 140 is configured to be positioned between the patient's fingers. The first band body 140 extends along a predetermined first direction.

[0082] like Figure 1 , Figure 2 As shown, the first belt body portion 140 has an end portion 141 located on the side of the support member 110, another end portion 143 located on the opposite side of the end portion 141, and a main body portion 145 extending between the end portion 141 and the other end portion 143.

[0083] like Figure 13 As shown, the first band body 140 can be configured, for example, to hook onto the interphalangeal portion fb located between the thumb and index finger of the patient's right hand H1 when the dilation member 180 is positioned at the first puncture site p1.

[0084] The second belt body 150 extends in a second direction, different from the first belt body 140's extending direction, i.e., the first direction. Specifically, as shown... Figure 5 As shown, the second belt body 150 extends from one side of the side portion 113 of the support member 110 ( Figure 5 (Extends to the left of)

[0085] like Figure 1 , Figure 2 As shown, the second belt body portion 150 has an end portion 151 located on the side of the support member 110, another end portion 153 located on the opposite side of the end portion 151, and a main body portion 155 extending between the end portion 151 and the other end portion 153.

[0086] The third belt body 160 extends in a third direction, which is different from both the first belt body 140's extending direction (the first direction) and the second belt body 150's extending direction (the second direction). Specifically, as... Figure 5 As shown, the third belt body portion 160 is located on the opposite side of the second belt body portion 150 from the side portion 113, separated by the support member 110. Figure 5 (Extends to the right of)

[0087] like Figure 1 , Figure 2 As shown, the third belt body portion 160 has one end portion 161 located on the side of the support member 110, another end portion 163 located on the opposite side of the one end portion 161, and a main body portion 165 extending between the one end portion 161 and the other end portion 163.

[0088] like Figure 11 , Figure 12 , Figure 13 As shown, the second band portion 150 and the third band portion 160 can be configured to wrap around the outer periphery of the right hand H1 when the hemostatic device 100 is worn on the patient's right hand H1.

[0089] The constituent materials of each belt section 140, 150, and 160 are not particularly limited, but can be, for example, made of vinyl chloride resin, polyurethane resin, polyester resin, etc. Furthermore, the shape, length, thickness, etc., of each belt section 140, 150, and 160 are not particularly limited.

[0090] like Figure 1 , Figure 2 As shown, the fixation component 120 has four fixation points: a first fixation point 171, a second fixation point 172, a third fixation point 173, and a fourth fixation point 174, which are capable of fixing each of the strap portions 140, 150, and 160 to the patient's right hand H1.

[0091] like Figure 1 As shown, a first fixing part 171 is disposed on the outer surface of the main body 155 of the second belt body 150. A second fixing part 172 is disposed on the outer surface of the main body 165 of the third belt body 160.

[0092] like Figure 2 As shown, a third fixing part 173 is disposed on the inner surface of the main body 155 of the second belt body 150. A fourth fixing part 174 is disposed on the inner surface of the main body 145 of the first belt body 140.

[0093] The first fixing part 171 and the second fixing part 172 are formed by the male side of the surface fastener. The third fixing part 173 and the fourth fixing part 174 are formed by the female side of the surface fastener. The surface fastener in this specification is a fastener that is installed and removed from the surface, such as Magic Tape (registered trademark) and Velcro (registered trademark).

[0094] The main body 155 of the second belt body 150 and the main body 165 of the third belt body 160 are configured to be detachable and detachable via the third fixing part 173 and the second fixing part 172. Furthermore, the main body 145 of the first belt body 140 and the main body 145 of the second belt body 150 are configured to be detachable and detachable via the first fixing part 171 and the fourth fixing part 174.

[0095] like Figure 1 As shown, in the second fixing portion 172 of the main body portion 165 of the third belt body portion 160, the end branches located on the other end 163 side of the third belt body portion 160 are multiple portions of a first branch portion 172a and a second branch portion 172b. Each branch portion 172a and 172b extends in a generally straight line from the starting point of the branch formed on the other end 161 side of the third belt body portion 160 toward the other end 163 side.

[0096] Furthermore, the specific construction of each fixing part 171, 172, 173, and 174 is not limited as long as the support member 110 and the expansion member 180 can be fixed to the patient's right hand H1 by connecting each band part 140, 150, and 160 to each other while the hemostatic device 100 is placed on the patient's right hand H1. For example, some fixing parts can be omitted, and the positions of the fixing parts in each band part 140, 150, and 160 can be changed. In addition, when each fixing part 171, 172, 173, and 174 is composed of surface fasteners, it is also possible to interchange the male and female sides of the surface fasteners. In addition, each fixing part 171, 172, 173, and 174 can also be constructed, for example, by a snap, button, clip, or a connecting mechanism having a frame part with holes or protrusions and a locking part with holes that can engage with the frame part.

[0097] <Injection Section>

[0098] like Figure 1 , Figure 2 As shown, the hemostatic device 100 has an injection section 201 for injecting fluid into the dilation member 180.

[0099] The injection unit 201 is composed of a connector with a built-in check valve (not shown). A syringe (not shown) can be connected to the injection unit 201.

[0100] A buffer member 202 with an expandable space is disposed between the injection section 201 and the expansion member 180. The buffer member 202 is composed of a flexible, bag-shaped member with an internal space. In addition, an arrow-shaped mark indicating the insertion direction of the syringe into the injection section 201 may be provided on the buffer member 202.

[0101] An injection section 201 is connected to one end of the buffer component 202. The inner cavity of the injection section 201 communicates with the space of the buffer component 202. However, the communication between the inner cavity of the injection section 201 and the space of the buffer component 202 is interrupted while the check valve built into the injection section 201 is closed.

[0102] A flexible tube 203 is connected to the other end of the buffer member 202. The inner cavity of the tube 203 communicates with the space of the buffer member 202. In addition, the other end of the tube 203, located on the opposite side of the end connected to the buffer member 202, is connected to the expansion member 180. The inner cavity of the tube 203 communicates with the inner cavity 183 of the expansion member 180.

[0103] While dilating the dilator 180, the surgeon inserts the top of the syringe (not shown) into the injection section 201 and opens the check valve. With the check valve of the injection section 201 open, the surgeon pushes the syringe plunger, thereby injecting air from the syringe into the inner cavity 183 of the dilator 180.

[0104] If air is injected into the cavity 183 of the dilator 180, the dilator 180 expands. If the dilator 180 expands, the buffer 202, which is connected to the cavity 183 of the dilator 180 via the tube 203, will inflate. The surgeon can visually confirm the expansion of the buffer 202, thereby easily determining that there is no air leakage and that the dilator 180 has expanded.

[0105] When the surgeon retracts the dilator 180, they insert the top of the syringe barrel into the injection section 201 and pull the syringe plunger. By performing this operation, the surgeon can expel air from the cavity 183 of the dilator 180 into the syringe.

[0106] Furthermore, the injection unit 201, the buffer unit 202, and the tube 203 can be prepared and provided in a state after being connected to the expansion unit 180, or they can be prepared and provided in a state after being separated from the expansion unit 180.

[0107] <Examples of the use of hemostatic instruments>

[0108] Next, refer to Figures 10 to 14 This section describes the first example of using the hemostatic device 100.

[0109] In the first use case, it is explained that the formation of Figure 10 The sequence of use of hemostatic instruments 100 when stopping bleeding at the first puncture site p1 of the patient's right hand H1 is shown.

[0110] Figure 11 This indicates the state after the completion of various surgical procedures using a sheath of a guide 300 inserted into the first puncture site p1.

[0111] When the surgeon places the hemostatic instrument 100 onto the patient's right hand H1, if... Figure 11 As shown, the expansion member 180 and the support member 110 are arranged such that they overlap with the first puncture site p1. At this time, the surgeon passes through the hole 117 formed in the support member 110 (see reference). Figure 7 While visually confirming the position of the marking portion 185 disposed on the expansion member 180, the marking portion 185 is disposed on the first puncture site p1, thereby enabling the expansion member 180 and the support member 110 to be properly positioned at the first puncture site p1.

[0112] When the surgeon applies the hemostatic device 100 to the patient's right hand H1, the support component 110 is positioned such that it overlaps with the metacarpal bone B1 of the index finger and the metacarpal bone B2 of the thumb. For example... Figure 10 As shown, the distance between the metacarpal bone B1 of the index finger and the metacarpal bone B2 of the thumb gradually narrows from the fingertip side towards the forearm A side. As described above, the width W of the support member 110 narrows from the upper end 111 side towards the lower end 112 (see reference). Figure 8 Therefore, the surgeon can configure the support member 110 in conjunction with the index finger metacarpal bone B1 and the thumb metacarpal bone B2. By configuring the support member 110 in conjunction with the index finger metacarpal bone B1 and the thumb metacarpal bone B2, the surgeon can prevent the formation of a gap between the expansion member 180 and the right hand H1.

[0113] like Figure 12 As shown, the surgeon wraps the second band body 150 and the third band body 160 around the circumference of the patient's right hand H1. The surgeon uses the third fixation point 173 (see reference) located on the inner surface of the second band body 150 to... Figure 2 ) and the second fixing part 172 disposed on the outer surface of the third belt body 160 (see reference) Figure 1 The second band portion 150 and the third band portion 160 can be connected via the fixing points 172 and 173. By connecting the band portions 150 and 160 to each other while the support member 110 overlaps with the metacarpal bone B1 of the index finger and the metacarpal bone B2 of the thumb, the surgeon can securely wrap the band portions 150 and 160 around the outer periphery of the right hand H1.

[0114] When the surgeon achieves hemostasis at the first puncture site p1, the third fixation portion 173, located on the inner surface of the second band body 150, can connect with the second branch 172b of the second fixation portion 172. The first puncture site p1 is located on the fingertip side of the patient's right hand H1, compared to the second puncture site p2 (see reference). Figure 10 Therefore, when the surgeon stops the bleeding at the first puncture site p1, the second band portion 150 and the third band portion 160 are connected via the second branch 172b, which is located on the forearm A side of the patient's right hand H1 compared to the first branch 172a, thereby reducing the range of restraint of the patient's right hand H1 by each band portion 150, 160.

[0115] Furthermore, the second fixing part 172 is disposed on the main body 165 of the third band body 160. Therefore, a portion of the main body 165 exists between the second fixing part 172 and one end 161 of the third band body 160. When the surgeon wraps the third band body 160 around the patient's right hand H1, pulling the main body 165 with one end 161 of the third band body 160 as a base point, it is possible to prevent the first branch 172a, which is not used in the connection between the second band body 150 and the third band body 160, from floating off the patient's right hand H1. For the reasons described above, when the surgeon connects the second band body 150 and the third band body 160 via the second branch 172b, it is possible to prevent the first branch 172a from floating off (see reference). Figure 15 , Figure 17 ).

[0116] Alternatively, the second fixing part 172 may not have the first branch 172a and the second branch 172b, and a structure may be adopted in which the third belt body 160 itself is divided into multiple parts (see reference). Figure 19 However, if the third band portion 160 is split at one end 161 located on the side of the covering portion 130, when the surgeon wraps the third band portion 160 around the patient's right hand H1, the second band portion 150 cannot suppress the entire area (side) of the covering portion 130 where the third band portion 160 is connected. Therefore, the fit of the covering portion 130 and the third band portion 160 relative to the right hand H1 is reduced. In addition, when the third band portion 160 is split, the portion of the third band portion 160 that is not connected to the second band portion 150 hangs down from the hemostatic device 100 when the hemostatic device 100 is not being used. Therefore, the third band portion 160 gets in the way when the hemostatic device 100 is being put on. In addition, when the third band portion 160 is split, it is necessary to increase the width of the third band portion 160. Therefore, it is difficult to make the widths of the second band portion 150 and the third band portion 160 approximately the same. Furthermore, it is difficult to apply force evenly relative to the positions where the second band portion 150 and the third band portion 160 are wound when the hemostatic device 100 is fitted onto the patient's right hand H1.

[0117] like Figure 13 As shown, the surgeon passes the first band body 140 through the interphalangeal portion fb located between the thumb and index finger of the patient's right hand H1, while simultaneously positioning a portion of the first band body 140 on the palm side of the patient's right hand H1. At this time, the surgeon uses the fourth fixation point 174 (refer to...) located on the inner surface of the first band body 140... Figure 2 ) and the first fixing part 171 disposed on the outer surface of the second belt body 150 (refer to Figure 1The first belt body 140 and the second belt body 150 can be connected via the fixed parts 172 and 174.

[0118] The support member 110 has a generally triangular shape with three sides. The hemostatic device 100 has three band portions 140, 150, and 160 arranged to extend from each side of the support member 110. Therefore, by connecting the band portions 140, 150, and 160 to each other, the hemostatic device 100 can fix the support member 110 to the patient's right hand H1 while applying equal force to each side of the support member 110.

[0119] Furthermore, the support member 110 has a shape that is symmetrical about the long axis C of the first band portion 140. Therefore, by wrapping the band portions 150 and 160, which extend in the left-right direction with reference to the first band portion 140, around the patient's right hand H1, the hemostatic device 100 can apply force evenly in the left-right direction relative to the support member 110. As a result, the hemostatic device 100 can prevent the support member 110 from shifting position when it is positioned on the patient's right hand H1.

[0120] With the syringe connected to the injection unit 201, the surgeon injects air into the dilation member 180, thereby dilating the dilation member 180. The hemostatic device 100 is as follows: Figure 14 When the expansion member 180 is expanded as shown, the expansion member 180 applies a compressive force relative to the first puncture site p1.

[0121] If the support member 110 expands the expansion member 180 while the hemostatic device 100 is worn on the patient's right hand H1, the expansion member 180 presses against the patient's right hand H1. Thus, the hemostatic device 100 can prevent the expansion member 180 from floating off the patient's right hand H1.

[0122] When a surgeon uses the hemostatic instrument 100 to achieve hemostasis, in order to increase the fixing force of the support member 110 relative to the patient's right hand H1, the first band portion 140 located on the interphalangeal joint fb can be tightened more forcefully. By tightening the first band portion 140 as described above, the surgeon can firmly fix the support member 110 to the patient's right hand H1 even if the support member 110 is positioned in an unstable state on the patient's right hand H1. However, if the first band portion 140 is tightened too forcefully as described above, the patient may sometimes experience pain. Therefore, in cases where it is impossible to forcibly tighten the first band portion 140 due to the patient's pain, the hemostatic instrument 100 may sometimes cause the lower surface 110a of the support member 110 to be tilted relative to the body surface of the patient's right hand H1.

[0123] In contrast to the aforementioned issues, the hemostatic device 100 is configured such that the thickness of the side portion 113 of the support member 110 decreases from the upper end 111 towards the lower end 112. Based on this, the first band portion 140, configured to be positioned between the fingers of the patient, extends from the upper end 111 side of the support member 110, pressing the upper end 111 side of the support member 110 against the patient's right hand F. Therefore, when the hemostatic device 100 is worn on the patient's right hand H1, if the expansion member 180 begins to expand, the expansion member 180 applies force to the upper end 111 of the support member 110. The support member 110 is lifted by the force applied by the expansion member 180. Thus, the support member 110... Figure 14 The lower surface 110a of the support member 110 is arranged substantially parallel to the body surface of the patient's right hand H1. Therefore, when the dilation member 180 is dilated, the hemostatic device 100 can apply pressure in the vertical direction relative to the first puncture site p1.

[0124] The corner portions 115a, 115b, and 115c of the support member 110 have rounded shapes (see reference). Figure 8 Therefore, when the dilator 180 expands and applies pressure to the puncture site p1, the hemostatic device 100 can prevent the corners 115a, 115b, and 115c of the support member 110 from biting into the patient's right hand H1.

[0125] By using the hemostatic instrument 100 in the above sequence, the surgeon can stop the bleeding at the first puncture site p1 on the patient's right hand H1.

[0126] Next, refer to Figures 15 to 17 This section describes the second to fourth examples of use of the hemostatic device 100. In the descriptions of the second to fourth examples of use, details already explained in the first example of use are appropriately omitted.

[0127] Figure 15 This illustrates a second example of the use of the hemostatic device 100. The second example involves using the hemostatic device 100 at the second puncture site p2 (see reference). Figure 10 A method for stopping bleeding. In the second example, the surgeon uses the third fixation point 173 (refer to) located on the inner surface of the second belt body 150 to achieve hemostasis. Figure 2 ) and the first branch 172a of the second fixing part 172 disposed on the outer surface of the third belt body 160 (refer to Figure 1 The second belt body 150 and the third belt body 160 can be connected via the fixed parts 172 and 173.

[0128] When the surgeon stops the bleeding at the second puncture site p2, the second band body 150 and the third band body 160 are connected by the first branch 172a, which is located on the fingertip side of the patient compared to the first branch 172a. This reduces the range of restraint of the patient's right hand H1 by the band bodies 150 and 160.

[0129] Figure 16 This indicates the third example of the use of hemostatic device 100.

[0130] The third application example is a method of using hemostatic device 100 to stop bleeding at the third puncture site p3 formed on the patient's left hand H2. In the third application example, the surgeon, similar to when stopping bleeding at the first puncture site p1, fixes the third fixation point 173 (see reference) located on the inner surface of the second band body 150. Figure 2 ) and the second branch 172b of the second fixing part 172 disposed on the outer surface of the third belt body 160 (refer to Figure 1 The second belt body 150 and the third belt body 160 can be connected via the fixed parts 172 and 173.

[0131] When the surgeon stops the bleeding at the third puncture site p3, the second band portion 150 and the third band portion 160 are connected by the second branch 172b, which is located on the forearm A side of the patient's left hand H2 compared to the first branch 172a. This reduces the range of restraint on the patient's left hand H2 by the band portions 150 and 160.

[0132] Figure 17 This indicates the fourth example of the use of hemostatic device 100.

[0133] The fourth application example is a method of using hemostatic device 100 to stop bleeding at the fourth puncture site p4 formed on the patient's left hand H2. In the fourth application example, the surgeon, similar to when stopping bleeding at the second puncture site p2, uses the third fixation point 173 (see reference) located on the inner surface of the second band body 150. Figure 2 ) and the first branch 172a of the second fixing part 172 disposed on the outer surface of the third belt body 160 (refer to Figure 1 The second belt body 150 and the third belt body 160 can be connected via the fixed parts 172 and 173.

[0134] When the surgeon stops the bleeding at the fourth puncture site p4, the second band portion 150 and the third band portion 160 are connected via the first branch 172a, which is located on the fingertip side of the patient's left hand H2 compared to the second branch 172b. This reduces the range of restraint on the patient's left hand H2 by the band portions 150 and 160.

[0135] The hemostatic device 100 according to this embodiment includes: a support member 110 configured to cover the first puncture site p1; a fixing member 120 configured to fix the support member 110 to the first puncture site p1; and an expansion member 180 connected to the support member 110 and configured to compress the first puncture site p1. The support member 110 has: an upper end portion 111 located at the front end of the expansion member 180 and forming an end of the support member 110; a lower end portion 112 located at the base end of the expansion member 180 and forming an end opposite to the upper end portion 111; and a side portion 113 connecting the upper end portion 111 and the lower end portion 112. The support member 110 has greater rigidity than the expansion member 180. The fixing member 120 is configured to be disposed between the patient's fingers, and has a first band portion 140 extending in a first direction and a second band portion 150 extending in a second direction different from the first direction. The support member 110 is configured such that its width W narrows from the upper end 111 toward the lower end 112, and the thickness of the side portion 113 thins from the upper end 111 toward the lower end 112. The first belt body portion 140 extends from the upper end 111 side along a first direction, and the second belt body portion 150 extends from the side portion 113 side along a second direction.

[0136] The hemostatic device 100 configured as described above has a support member 110, which has greater rigidity than the expansion member 180. When hemostasis is achieved at a first puncture site p1 formed at a predetermined location avoiding the metacarpal bone B1 of the index finger and the metacarpal bone B2 of the thumb of the patient's right hand H1, the support member 110 is positioned to cover the first puncture site p1 together with the expansion member 180. By pressing the expansion member 180 against the patient's right hand H1, the support member 110 can prevent the expansion member 180 from floating off the patient's right hand H1. Furthermore, the width W of the support member 110 narrows from the upper end 111 towards the lower end 112. Therefore, when the support member 110 is positioned on the patient's right hand H1, it can be aligned with the metacarpal bone B1 of the index finger and the metacarpal bone B2 of the thumb. Thus, the second band portion 150 can be securely wound around the outer periphery of the patient's right hand H1. Furthermore, the support member 110 is configured such that the thickness of the side portion 113 decreases from the upper end 111 towards the lower end 112. Moreover, the first band portion 140, configured to be positioned between the fingers of the patient, is configured to extend from the upper end 111 side of the support member 110, pressing the upper end 111 side of the support member 110 against the patient's right hand H1. Therefore, when hemostasis is initiated with the hemostatic device 100 fitted onto the patient's right hand H1, the expansion member 180 can apply force to the upper end 111 of the support member 110. The support member 110 is lifted by the force applied by the expansion member 180. Thus, the lower surface 110a of the support member 110 is positioned substantially parallel to the body surface of the patient's right hand H1. Therefore, with the dilator 180 and support 110 positioned at the first puncture site p1, the hemostatic device 100 fixes the first band portion 140 and the second band portion 150 to the patient's right hand H1, thereby applying pressure to the dilator 180 in the vertical direction relative to the first puncture site p1. Thus, the hemostatic device 100 can effectively apply pressure to the first puncture site p1.

[0137] In addition, the support member 110 has a shape that is symmetrical about the left and right sides with respect to the major axis C of the first belt body 140.

[0138] In the hemostatic device 100 configured as described above, the support member 110 has a shape that is symmetrical about the long axis C of the first band portion 140. Therefore, by wrapping each band portion 150, 160, extending in the left-right direction based on the first band portion 140, around the patient's right hand H1, an equal tensile force can be applied to the support member 110 in the left-right direction. Thus, when the hemostatic device 100 is positioned with the support member 110 on the patient's right hand H1, positional displacement of the support member 110 can be prevented.

[0139] Additionally, the fixing member 120 has a third belt body portion 160 extending along a third direction different from the first and second directions. The third belt body portion 160 extends along the third direction from a side portion 113 located on the opposite side of the second belt body portion 150 across the support member 110. The third belt body portion 160 has: an end portion 161 located on the support member 110 side; another end portion 163 located on the opposite side of the end portion 161; and a main body portion 165 extending between the end portion 161 and the other end portion 163. The main body portion 165 has a second fixing portion 172 detachably configured relative to the second belt body portion 150. The end portion 172 located on the other end portion 163 side branches into multiple portions 172a, 172b.

[0140] When the hemostatic device 100 configured as described above is wrapped around the patient's right hand H1, by pulling the main body 165 with one end 161 of the third strap 160 as a base point, the first branch 172a (or second branch 172b) of the second fixing part 172, which is not used in the connection between the second strap 150 and the third strap 160, can be prevented from floating off the patient's right hand H1. Furthermore, when connecting the second strap 150 and the third strap 160, the surgeon can selectively connect the third fixing part 173 disposed on the inner surface of the second strap 150 with respect to the first branch 172a and the second branch 172b. Therefore, when the hemostatic device 100 is worn on the patient's right hand H1, the range of restraint of the patient's right hand H1 by each strap part 150, 160 can be reduced.

[0141] In addition, the corners 115a, 115b, and 115c of the support member 110 located on the outer peripheral side have a rounded shape.

[0142] Because the hemostatic device 100 has the above-described configuration, when the dilator 180 expands and applies pressure to the first puncture site p1, it can prevent the corners 115a, 115b, and 115c of the support member 110 from biting into the patient's right hand H1.

[0143] Additionally, the support member 110 has a hole 117 at a position where it overlaps with the expansion member 180.

[0144] Because the hemostatic device 100 has the aforementioned configuration, when the surgeon positions the dilator 180 and the support member 110 toward the first puncture site p1, the position of the marking portion 185 positioned on the dilator 180 can be visually confirmed via the hole 117 formed in the support member 110. Therefore, the hemostatic device 100 can properly position the dilator 180 at the first puncture site p1 based on the marking portion 185.

[0145] Next, a hemostatic device according to a variation of the first embodiment and a hemostatic device according to the second embodiment will be described. In the following description, explanations regarding the order of use of components and hemostatic devices already described in the first embodiment will be appropriately omitted. Furthermore, any aspects of the variations and the second embodiment not specifically described can be considered the same as those in the first embodiment.

[0146] <Variation Example>

[0147] The shape of the second fixing part 172 disposed on the third belt body 160 can be arbitrarily changed. For example, as Figure 18 As shown, the second fixing part 172 can also be configured in a heart shape, such as forming two branches 172a and 172b on the other end 163 side of the third belt part 160.

[0148] <Second Implementation>

[0149] like Figure 19 As shown, in the hemostatic device 100A of the second embodiment, the fixing member 120 has a third belt portion 160 extending in a third direction different from the first direction and the second direction.

[0150] The third belt body 160 is located on the opposite side of the second belt body 150 via the support member 110 (see reference). Figure 8 It extends along the third direction.

[0151] The third belt body portion 160 has: one end portion 161 located on the side of the support member 110; another end portion 163 located on the opposite side of the one end portion 161; and a main body portion 165 extending between the one end portion 161 and the other end portion 163.

[0152] The third body part 160 branches into part 160a and part 160b at the main body part 165.

[0153] The second fixing part 172 can be configured on both part 160a and part 160b.

[0154] In the second embodiment of the hemostatic device 100A, when the surgeon connects the second band body 150 and the third band body 160, the third fixing portion 173 (see reference) disposed on the inner surface of the second band body 150 can be fixed. Figure 2 The first part 160a and the second part 160b are selectively connected. Thus, the hemostatic device 100A of the second embodiment, like the hemostatic device 100 of the first embodiment, can reduce the range of restraint of the patient's right hand H1 by each of the strap parts 150 and 160 when the hemostatic device 100A is worn on the patient's hand H.

[0155] <Examples of variations of the support components>

[0156] The following is for reference Figures 20 to 24 This illustrates a variation of the supporting component.

[0157] like Figure 20 As shown, no hole 117 is formed in the support member 110A (see reference). Figure 7 In this way, the hole 117 can be omitted from the support member 110A. Furthermore, without the hole 117 as in the support member 110A, the portion of the support member 110A that overlaps with the marking portion 185 (see reference) can be accommodated. Figure 6 The support component 110A is integrally formed to be transparent.

[0158] like Figures 21 to 24 As shown, the planar shape of the support member is not particularly limited as long as it is formed such that the width of the support member narrows from the upper end 111 towards the lower end 112.
