Hemostatic device

Abstract

When a tube portion is attached to or detached from a tube fixing portion by an operator in a state where a hemostasis device is attached to a patient's hand, unintended application of external force to a puncture site and / or unintended application of external force to a dilating member to cause the hemostasis device to be displaced are prevented. A hemostasis device (100) has a tube fixing portion (300) provided in a fixing member that fixes a dilating member (110). The tube fixing portion includes a first member (310), a second member (320) located on the dilating member side compared to the first member, a slit portion (330), and a tube holding portion (340). A portion of the first member is located away from the dilating member in a direction perpendicular to an imaginary plane (S) formed with respect to the slit portion, a first front surface (313) includes a first region (313a) that is not opposed to a second front surface (323) and a second region (313b) that is opposed to the second front surface, and a first curved portion (312) has a first curved surface (312a) that is curved toward the second member side and is opposed to the second front surface (323).

Description

Technical Field

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

[0002] As a type of catheter surgery, it is known to insert various long medical devices into blood vessels through a puncture site formed by piercing a blood vessel in the patient's arm or hand, and to perform treatment or intervention on the lesion site. For example, Patent Document 1 discloses a hemostatic device for stopping bleeding at a puncture site formed to allow delivery to a blood vessel (including the distal radial artery) traveling in the hand.

[0003] The hemostatic device of Patent Document 1 comprises: an expansion member that applies pressure to a puncture site formed on a patient's hand; a fixing member for fixing the pressing member to the patient's hand; an injection member having a port (connector portion) configured to inject fluid for expanding the expansion member and a tube portion connecting the connector portion to the inner cavity of the expansion member; and a tube fixing portion located on the fixing member and configured to fix the tube portion.

[0006] Patent Document 1: International Publication No. 2019 / 090104 Summary of the Invention

[0007] When a physician or other practitioner (hereinafter referred to as "the practitioner") uses the hemostatic device of Patent Document 1 to stop bleeding at a puncture site on a patient's hand, the hemostatic device is secured using various straps while the dilator is positioned at and around the puncture site on the patient's hand. This prevents the dilator from dislodging from the puncture site on the patient's hand. Furthermore, by securing the tube to the tube fixing part, the practitioner can reduce the movement of the tube in response to the patient's hand movements.

[0008] However, the hemostatic device described in Patent Document 1 may present the following problems.

[0009] In the hemostatic device of Patent Document 1, a groove for fixing the tube is provided in the tube fixing part. Therefore, when the operator attaches or detaches the tube relative to the tube fixing part, the operator needs to apply external force to the tube to deform the tube fixing part in the expansion direction of the groove (e.g., elastic deformation). At this time, the force required by the operator to deform the tube fixing part in the expansion direction of the groove depends on the mechanical structure of the tube fixing part, but there are cases where its structure is not designed with the operator's operability and convenience in mind.

[0010] For example, if the surgeon requires a large force to attach or detach the tube from the fixation part, the external force (the force applied by the surgeon) is transmitted to the dilation part via the fixation part, which has the tube fixation part. Therefore, there is a possibility that external force is unintentionally applied to the puncture site. In addition, because external force is transmitted to the fixation part, external force is unintentionally transmitted to the dilation part, thereby there is a possibility that the dilation part is displaced from the puncture site formed on the patient's hand.

[0011] In view of the above-mentioned problems, the present invention aims to prevent unintentional external force on the puncture site caused by the external force applied by the practitioner to the tube relative to the tube fixation part when the hemostatic device is worn on the patient's hand and the practitioner is attaching or detaching the tube relative to the tube fixation part, and / or to prevent misalignment of the hemostatic device that may occur due to the external force applied by the practitioner to the tube being transmitted through the tube fixation part to the fixation part and unintentionally applying external force to the dilation part.

[0012] The hemostatic device of the present invention comprises: an expansion member configured to compress a hemostatic site on a patient's limb; a fixing member configured to fix the expansion member to the patient's limb; an injection member having a connector portion configured to inject fluid for expanding the expansion member, and a tube portion connecting the connector portion to the inner cavity of the expansion member; and a tube fixing portion located on the fixing member and configured to fix the tube portion, the tube fixing portion comprising: a first member; a second member located on the expansion member side and opposite to the first member; a slit portion formed between the first member and the second member and configured to allow insertion of the tube portion; and a tube holding portion surrounded by the first member, the second member, and the slit portion and configured to hold the tube portion. The first component has a first main body, a first curved portion that bends toward the second component, and a first front end face located at the front end of the first curved portion. The second component has a second main body, a second curved portion that bends toward the first component, and a second front end face located at the front end of the second curved portion and facing the first front end face across the slit. A portion of the first component moves away from the expansion member in a direction perpendicular to the imaginary plane formed by the slit, compared to the second component. The first front end face has a first region that does not face the second front end face across the slit and a second region that faces the second front end face across the slit. The first curved portion has a first curved surface that bends toward the second component, and the first curved surface faces the second front end face across the tube holding portion.

[0013] Invention Effects

[0014] The hemostatic device constructed as described above reduces the area where the front ends of the first component (first front end face) and the front ends of the second component (second front end face) face each other across the slit by creating a height difference between the first and second components constituting the tube fixing part. Therefore, when the tube is pressed into the tube fixing part by the practitioner (insertion into the tube fixing part), the second component deforms after the first component deforms in the direction of expansion of the slit. This reduces the force required for the practitioner to insert the tube into the tube fixing part while it is worn on the patient's hand. Furthermore, the first component of the hemostatic device has a first curved surface at a position facing the second front end face of the second component across the tube holding part. Therefore, when the tube is pulled away from the tube fixing part by the practitioner (removal from the tube fixing part), the first curved surface acts as a guiding surface, causing the tube to move from the tube holding part towards the slit. This reduces the force required for the practitioner to remove the tube from the tube fixing part. In this way, the hemostatic device described above can suppress the force required by the operator to attach or detach the tube relative to the tube fixation part when it is worn on the patient's hand, thus preventing unintentional application of external force to the puncture site, and / or preventing misalignment of the hemostatic device that may occur due to unintentional application of external force to the dilation component.

[0032] 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 the meaning of the terms used in the claims. Furthermore, for ease of explanation, the dimensions in the drawings may be exaggerated and differ from the actual dimensions.

[0033] Figures 1-10 This is a diagram illustrating the hemostatic device 100 of this embodiment. Figures 11-16 This is a diagram illustrating an example of the use of the hemostatic device 100.

[0034] 100 hemostatic devices, such as Figure 11 , Figures 14-16 As shown, when the sheath of the guide 200, which is placed on the hand H at a position distal to the patient's forearm A (finger side), is removed, it can be used to stop bleeding at the puncture site.

[0035] The specific location of the puncture site that becomes the target of hemostasis for the hemostatic device 100 is not particularly limited. In this embodiment, the first puncture site p1 is exemplified below.

[0036] The first puncture site, p1, is as follows: Figure 11 As shown, the puncture site is formed at the artery B (hereinafter also referred to as "vessel B") of the palmar artery, which runs on the back of the right hand (H1, hand H) on the Hb side, located distal to the patient's forearm A, in the snuffbox. Furthermore, the snuffbox is the cavity near the radius bone in the hand when the patient opens their thumb.

[0037] The second puncture site p2 is as follows Figure 11 The image shows the puncture site located distal to the nasal cavity of the palmar artery, which runs on the dorsum of the patient's right hand (H1). The second puncture site, p2, is located distal to the right hand (H1) from the extensor pollicis longus tendon t on the dorsum of the patient's right hand (H1), with reference to the first puncture site, p1.

[0038] The following is a detailed description of 100 hemostatic instruments.

[0039] <Hemostatic Instruments>

[0040] Regarding hemostatic instruments (100 items), roughly speaking, such as... Figures 1-4 , Figures 14-16 As shown, it includes: an expansion member 110 configured to compress a first puncture site p1 formed on the patient's right hand H1; a fixation member 120 configured to fix the expansion member 110 to the patient's right hand H1; an injection member 180 having a connector portion 181 configured to inject fluid for expanding the expansion member 110, and a tube portion 183 connecting the connector portion 181 to the inner cavity 113 of the expansion member 110; and a tube fixing portion 300 located on the fixation member 120 and configured to fix the tube portion 183.

[0041] <Expansion Components>

[0042] Expansion component 110, such as Figure 6 , Figure 7 As shown, it can be composed of a balloon having an inner cavity 113 divided by a membrane material.

[0043] The expansion member 110 can be formed, for example, by joining the edges of two sheet-like membrane materials with an inner cavity 113 formed between two sheet-like membrane materials that are generally rectangular in shape. Alternatively, the expansion member 110 can also be composed, for example, a sheet-like membrane material that is formed in a bag-like shape with an inner cavity.

[0044] The expansion member 110 expands by supplying fluid such as air into the inner cavity 113, and contracts by discharging the fluid supplied to the inner cavity 113. Furthermore, in Figure 6 , Figure 7 The image shows a cross-sectional view of the expansion member 110 as fluid is supplied to it and the expansion member 110 expands.

[0045] The membrane material constituting the expansion member 110 can be, for example, made of a resin material having a specified thickness. A tube 183 (described later) is connected to the inner cavity 113 of the expansion member 110. Figure 1 , Figure 2 ).

[0046] The material of the membrane constituting the expansion member 110 is not particularly limited. It can be 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, silicone, polyurethane, polyamide elastomer, polyurethane elastomer, polyester elastomer, nylon, nylon elastomer, or any combination thereof (mixed resin, polymer alloy, laminate, etc.).

[0047] Expansion component 110, such as Figure 6 , Figure 7 , Figure 15 , Figure 16 As shown, the support member 130 is disposed on the inner surface 130a side of the support member 130 included in the fixing member 120. The inner surface 130a of the support member 130 is disposed on the body surface side of the patient's hand H when the hemostatic device 100 is fitted onto the patient's hand H. In addition, the outer surface 130b of the support member 130 is the surface located on the opposite side of the inner surface 130a.

[0048] The expansion member 110 can be directly connected to the inner surface 130a of the support member 130. The connection between the expansion member 110 and the support member 130 can be achieved by, for example, welding or bonding.

[0049] In addition, the expansion member 110 may also be connected to the inner surface 130a of the support member 130 via other components.

[0050] Alternatively, the expansion member 110 may be composed of a film-like member in such a way that an inner cavity is formed between it and the inner surface 130a of the support member 130. For example, the expansion member 110 may be configured to directly connect a film-like member to the inner surface 130a of the support member 130, and to have an inner cavity between the inner surface 130a of the support member 130 and the film-like member.

[0051] Expansion component 110 in Figures 1-5The shape shown is circular when viewed in plan view. However, the shape of the expansion member 110 when viewed in plan view is not limited to a circle. In addition, there are no particular restrictions on the cross-sectional shape of the expansion member 110 before and after expansion, or on the specific structure of the expansion member 110.

[0052] On the expansion component 110, such as Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 15 , Figure 16 As shown, a mark 115 is provided for aligning the expansion member 110 with the first puncture site p1.

[0053] The mark 115 is disposed on the outer surface of the side opposite to the side of the support member 130 of the expansion member 110 (the side disposed on the body surface side of the patient's hand H when the hemostatic device 100 is worn on the patient's hand H).

[0054] The specific placement of the mark 115 is not particularly limited as long as it is disposed on the expansion member 110. The mark 115 may also be disposed, for example, on the inner surface of the expansion member 110 on the side opposite to the side on which the support member 130 is disposed (when the hemostatic device 100 is worn on the patient's hand H, it is disposed on the body surface side of the patient's hand H).

[0055] like Figure 5 As shown, mark 115 is positioned approximately at the center of the expansion member 110 in the planar direction. Furthermore, mark 115 is positioned to overlap approximately at the center of the support member 130 in the planar direction. Additionally, the planar directions of the expansion member 110 and the support member 130 are... Figure 5 The planar view shown indicates the extension direction of the support member 130 (expansion member 110).

[0056] The mark 115 can be formed, for example, into a rectangular shape with the entire mark 115 being colored. Furthermore, the shape, size, color, forming method, and position of the mark 115 are not particularly limited. For example, the mark 115 may also be provided on the support member 130.

[0057] <Fixed components>

[0058] Fixed component 120, such as Figure 1 As shown, it has a support member 130 and a plurality of straps 140, 150, 160 configured to be connected to the support member 130 and configured to be wrapped around the patient's hand H.

[0059] <Supporting Components>

[0060] Support component 130, such as Figures 3-7As shown, there is a first region 131 with an expansion member 110 and a second region 132 located on the outside of the first region 131 and configured to connect the first belt 140, the second belt 150 and the third belt 160.

[0061] Support component 130 in Figure 5 When viewed from a plane, it has a circular shape.

[0062] Area 131 is Figure 5 The area overlapping with the expansion member 110 is shown in planar view. Region 132 is... Figure 5 The region shown is located on the outer side compared to region 131 when viewed from a planar perspective.

[0063] Furthermore, the first region 131 can be arbitrarily defined based on the shape and size of the expansion member 110 disposed on the support member 130. Additionally, the second region 132 can be defined based on its relative positional relationship with the first region 131. Therefore, the first region 131 and the second region 132 can be appropriately modified according to the shape and size of the expansion member 110 disposed on the support member 130.

[0064] like Figures 6-8 As shown, the center point R, which becomes the center when the first belt 140 and the second belt 150 slide along the second holes 133b and 133c, is located in the first region 131. The center point R is located approximately at the center of the support member 130 in the surface direction. Therefore, the center point R is as follows: Figure 6 , Figure 7 As shown, when projected onto the expansion member 110, it is located at a position overlapping with the mark 115.

[0065] In region 2, 132, such as Figures 5-9 As shown, a first hole 133a is formed and a pair of second holes 133b and 133c are formed opposite each other, separated by an expansion member 110.

[0066] like Figure 5 As shown, when the hemostatic device 100 is fitted onto the patient's hand H, the first hole 133a is positioned on the distal side (fingertip side) of the hand H compared to the expansion member 110.

[0067] like Figure 5 As shown, the second hole 133b and the second hole 133c are on the same straight line connecting the first hole 133a and the expansion member 110 (and the same straight line connecting the first hole 133a and the tube fixing part 300). Figure 5 The straight line is shown as an imaginary line C) and is arranged with an expansion member 110 in between in the direction of the intersection.

[0068] Each hole 133a, 133b, 133c as follows Figures 3-5 As shown, it is arranged on an imaginary circle along the outline of the support member 130.

[0069] like Figures 3-7 As shown, a first belt body 140 is connected to the second hole 133b. A second belt body 150 is connected to the second hole 133c. A third belt body 160 is connected to the first hole 133a.

[0070] like Figure 5 As shown, the width of one end 141 of the first belt body 140 is smaller than the length of the hole in the second hole 133b. Therefore, the first belt body 140 is as follows: Figure 8 As shown, with one end 141 of the first belt 140 connected to the second hole 133b, it can slide around the expansion member 110 in the second region 132 with the center point R of the support member 130 as the center.

[0071] like Figure 5 As shown, the width of one end 151 of the second belt body 150 is smaller than the length of the second hole 133c. Therefore, the second belt body 150 is as follows: Figure 8 As shown, with one end 151 of the second belt 150 connected to the second hole 133c, it can slide around the expansion member 110 in the second region 132 with the center point R as the center.

[0072] The angle (sliding range) at which the first belt body 140 and the second belt body 150 can slide around the expansion member 110 with the center point R as the center is not particularly limited. For example, it can be set to 1° to 75°.

[0073] like Figure 5 As shown, the width of one end 161 of the third belt 160 is approximately the same as the length of the hole in the first hole 133a. Therefore, when the third belt 160 is connected to the first hole 133a, its sliding movement around the center point R is restricted.

[0074] like Figure 8 , Figure 9 As shown, in the second region 132 of the support member 130, a portion having a first hole 133a and a tube fixing portion 300 is formed, extending from the expansion member 110 toward the departure side. Figure 6 , Figure 7 The first curved region 134a, which is curved into a convex shape on the upper side, is convex.

[0075] In addition, such as Figure 8 , Figure 9 As shown, the portion in the second region 132 of the support member 130 where the second holes 133b and 133c are disposed forms a portion facing the expansion member 110. Figure 6, Figure 7 The second curved region 134b (below side) is curved into a convex shape.

[0076] The support component 130 is made of a material that is harder than the belts 140, 150, and 160.

[0077] As the constituent material of the support component 130 with the aforementioned hardness, materials such as acrylic resin, polyvinyl chloride (especially rigid polyvinyl chloride), polyethylene, polypropylene, polyolefins such as polybutadiene, polystyrene, poly-(4-methyl-1-pentene), polycarbonate, ABS resin, polymethyl methacrylate (PMMA), polyacetal, polyacrylate, polyacrylonitrile, polyvinylidene fluoride, ionomer, acrylonitrile-butadiene-styrene terpolymer, polyethylene terephthalate (PET), etc., can be used.

[0078] In each of the expansion member 110 and the support member 130, Figure 3 , Figure 4 The overlapping portions shown in the planar view can be made transparent. In the case where the expansion member 110 and the support member 130 are configured as such, as... Figure 12 , Figure 13 , Figure 14 As shown, when the hemostatic device 100 is fitted onto the patient's right hand H1, the operator can more easily visually confirm the position of the marker 115 and / or the first puncture site p1 via the dilation member 110 and the support member 130. Furthermore, the term "transparent" includes colored transparent, colorless transparent, and translucent.

[0079] <Body>

[0080] First band body 140 Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it has an end portion 141 configured to connect to the second hole portion 133b of the support member 130, a free other end portion 143 not connected to the support member 130, and a main body portion 145 extending between the end portion 141 and the other end portion 143.

[0081] The second band is 150. Figures 1-5 As shown, it has an end portion 151 configured to connect to the second hole portion 133c of the support member 130, a free other end portion 153 not connected to the support member 130, and a main body portion 155 extending between the end portion 151 and the other end portion 153.

[0082] The first belt 140 extends from the support member 130 in a predetermined first direction. The second belt 150 extends from the support member 130 in a predetermined second direction different from the first direction.

[0083] The first band 140 and the second band 150 are as follows Figure 12 , Figure 13 , Figure 14 As shown, it is 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.

[0084] The third band 160 Figures 1-5 As shown, it has an end portion 161 configured to connect to the first hole portion 133a of the support member 130, a free other end portion 163 not connected to the support member 130, and a main body portion 165 extending between the end portion 161 and the other end portion 163.

[0085] The third belt 160 extends from the support member 130 in a third direction that is different from the first direction in which the first belt 140 extends and the second direction in which the second belt 150 extends.

[0086] The third band 160 Figure 14 As shown, it is configured to hang on the interphalangeal part fb between the thumb and index finger of the patient's right hand H1 while the expansion member 110 is positioned at the first puncture site p1.

[0087] Each end 141, 151, 161 of each strap 140, 150, 160 can be configured to pass through and wrap around the holes 133a, 133b, 133c of the support member 130. Furthermore, the construction for connecting each end 141, 151, 161 of each strap 140, 150, 160 to the support member 130 is not particularly limited. For example, a component (e.g., a hook and loop fastener) can be provided at each end 141 to maintain and release the strap from the holes 133a, 133b, 133c of the support member 130.

[0088] Furthermore, a mark M (including graphics and text) is provided on each end 141, 151, and 161 of each of the bands 140, 150, and 160 to identify each band 140, 150, and 160. In this embodiment, the number "1" is provided on the end 141 of the first band 140, the number "2" is provided on the end 151 of the second band 150, and the number "3" is provided on the end 161 of the third band 160. The numbers on each band 140, 150, and 160 correspond to the order in which the practitioner wraps each band 140, 150, and 160 when placing the hemostatic instrument 100 on the patient's right hand H1. Therefore, by visually recognizing the mark M, the practitioner can place each band 140, 150, and 160 on the patient's right hand H1 in the correct order. Furthermore, the size, color, method of formation, and position of the mark M are not particularly limited.

[0089] The constituent materials of each belt 140, 150, and 160 are not particularly limited, and can be made of, for example, vinyl chloride resin, amide resin, amide elastomer resin, polyurethane resin, polyester resin, etc. Furthermore, there are no particular restrictions on the shape, length, thickness, etc., of each belt 140, 150, and 160.

[0090] 100 hemostatic instruments Figures 1-4 As shown, it has five fixing parts: a first fixing part 171, a second fixing part 172, a third fixing part 173, a fourth fixing part 174, and a fifth fixing part 175.

[0091] like Figure 1 , Figure 3 As shown, a first fixing part 171 is disposed on the outer surface of the first belt body 140. A second fixing part 172 is disposed on the outer surface of the second belt body 150.

[0092] like Figure 2 , Figure 4 As shown, a third fixing part 173 is disposed on the inner surface of the first belt body 140. A fourth fixing part 174 is disposed on the inner surface of the second belt body 150. A fifth fixing part 175 is disposed on the inner surface of the third belt body 160.

[0093] The “inner surface” of each belt body 140, 150, and 160 is the side of the patient’s body surface when the hemostatic device 100 is worn on the patient, and the “outer surface” of each belt body 140, 150, and 160 is the side of the inner surface.

[0094] The first fixing part 171 and the second fixing part 172 are formed by the male side of the hook and loop fastener. The third fixing part 173, the fourth fixing part 174, and the fifth fixing part 175 are formed by the female side of the hook and loop fastener. The hook and loop fasteners in this specification are fasteners that can be attached and detached from the front, such as Magic Tape (registered trademark) and Velcro (registered trademark).

[0095] Each fixing part 171, 172, 174, and 175 is used to connect each band body 140, 150, and 160 to each other when the hemostatic device 100 is placed on the patient's right hand H1. Additionally, each end 141, 151, and 161 of each fixing part 173, 174, and 175 is used to connect each band body 140, 150, and 160 to the support member 130. Furthermore, the specific construction of each fixing part 171, 172, 174, and 175 is not limited as long as it can fix the support member 130 to the patient's right hand H1. For example, it is possible to omit some fixing parts and change the position of the fixing parts in each band body 140, 150, and 160. Furthermore, if each fixing part 171, 172, 173, 174, and 175 is made of hook and loop fasteners, the male and female sides of the hook and loop fasteners can be interchanged. In addition, each fixing part 171, 172, 173, 174, 175 may also be composed of, for example, a frame having snaps, buttons, clips, holes and a connecting mechanism having a locking part having a protrusion that can engage with the frame.

[0096] <Injection Components>

[0097] Injection component 180 such Figure 1 , Figure 2 As shown, it has a connector portion 181 configured to be able to inject fluid for expanding the expansion member 110, and a tube portion 183 connecting the connector portion 181 to the inner cavity 113 of the expansion member 110.

[0098] The connector section 181 has a built-in check valve (not shown). A syringe (not shown) can be connected to the connector section 181.

[0099] A buffer member 182 with expandable space is disposed between the connector portion 181 and the expansion member 110. The buffer member 182 is composed of a flexible bag-shaped member with a space formed inside. In addition, an arrow-shaped mark indicating the insertion direction of the syringe into the connector portion 181 may be provided on the buffer member 182.

[0100] A connector portion 181 is connected to one end of the buffer member 182. The inner cavity of the connector portion 181 communicates with the space of the buffer member 182. However, during the period when the check valve built into the connector portion 181 is closed, the communication between the inner cavity of the connector portion 181 and the space of the buffer member 182 is cut off.

[0101] A flexible tube 183 is connected to the other end of the buffer member 182. The inner cavity of the tube 183 communicates with the space of the buffer member 182. In addition, the other end of the tube 183 opposite to the end connected to the buffer member 182 is connected to the expansion member 110. The inner cavity of the tube 183 communicates with the inner cavity 113 of the expansion member 110.

[0102] When the operator expands the dilator 110, the operator inserts the front barrel of the syringe (not shown) into the connector 181 and opens the check valve. With the check valve of the connector 181 open, the operator pushes the plunger of the syringe, thereby injecting air from the syringe into the inner cavity 113 of the dilator 110.

[0103] If air is injected into the cavity 113 of the expansion member 110, the expansion member 110 expands. If the expansion member 110 expands, the buffer member 182, which communicates with the cavity 113 of the expansion member 110 via the tube 183, expands. By visually confirming the expansion of the buffer member 182, the practitioner can easily ascertain that there is no air leakage and that the expansion member 110 has expanded.

[0104] When the operator contracts the dilator 110, they insert the front barrel of the syringe into the connector 181 and pull back the syringe pusher. By performing the above operation, the operator can expel air from the inner cavity 113 of the dilator 110 into the syringe.

[0105] Furthermore, the connector 181, buffer member 182, and tube 183 can be prepared and provided in a state connected to the expansion member 110, or in a state separated from the expansion member 110.

[0106] <Pipe Fixing Part>

[0107] Pipe fixing part 300 Figure 5 , Figure 10 As shown, the device includes a first component 310, a second component 320 located on the side of the expansion component 110 and opposite to the first component 310, a slit portion 330 formed between the first component 310 and the second component 320 and configured to allow insertion of the tube portion 183, and a tube holding portion 340 surrounded by the first component 310, the second component 320 and the slit portion 330 and configured to hold the tube portion 183.

[0108] Component 310 Figure 10 As shown, it has a first main body portion 311, a first curved portion 312 that bends toward the second component 320, and a first front end face 313 located at the front end of the first curved portion 312.

[0109] Component 2, 320, etc. Figure 10As shown, it has a second main body portion 321, a second curved portion 322 that bends toward the first component 310, and a second front end surface 323 located at the front end of the second curved portion 322 and opposite to the first front end surface 313 across the slit portion 330.

[0110] The first main body 311 and the second component 320 are as follows Figure 10 As shown, it extends from the support member 130 in a direction substantially perpendicular to the surface direction of the support member 130 and in a direction away from the support member 130. Furthermore, if... Figure 5 As shown in the enlarged view of the tube fixing part 300, the width Z1 of the first main body part 311 (hereinafter, "width" refers to...) Figure 5 The lengths of the first front end face 311, the width Z2 of the first front end face 313, the width Z3 of the second main body 321, and the width Z4 of the second front end face 323 are all set to equal values. Furthermore, the widths Z1 of the first main body 311, Z2 of the first front end face 313, Z3 of the second main body 321, and Z4 of the second front end face 323 are... Figure 1 The length of the tube fixing part in the left and right directions is 300.

[0111] like Figure 10 As shown, the width Y1 of the slit portion 330 formed between the first curved portion 312 and the second curved portion 322 (the "width" referred to here is...) Figure 10 The length in the left-right direction is less than the width Y2 of the tube holding part 340 and less than the diameter of the tube part 183. Therefore, the hemostatic device 100 can prevent the tube portion 183 inserted into the tube holding portion 340 from unintentionally dislodging from the tube fixing portion 300. Furthermore, the width Y2 of the tube holding portion 340 is preferably the same as the diameter of the tube portion 183. Equal. Through this configuration, the hemostatic device 100 can prevent the tube portion 183 from extending into the tube holding portion 340. Figure 5 It moves in the left and right directions. Additionally, the height of the tube holding part 340 (height referred to here as...) Figure 10 The length in the vertical direction is preferably the same as the diameter of the tube 183. Equal. Through this configuration, the hemostatic device 100 can prevent the tube portion 183 from extending into the tube holding portion 340. Figure 10 The hemostatic device 100 can move in the vertical direction. Therefore, it can prevent the tube portion 183 inserted into the tube holding portion 340 from unintentionally falling out of the tube fixing portion 300. In addition, the width Y1 of the slit portion 330 and the width Y2 of the tube holding portion 340 are Figure 1 The length of the tube fixing part 300 in the vertical direction.

[0112] A portion of the first component 310 (a portion of the first curved portion 312) moves away from the expansion component 110 in a direction perpendicular to the imaginary plane S formed relative to the slit portion 330, compared to the second component 320. The first front end surface 313 has a first region 313a that is not opposite to the second front end surface 323 across the slit portion 330, and a second region 313b that is opposite to the second front end surface 323 across the slit portion 330.

[0113] The imaginary plane S formed by the slit portion 330 mentioned here is as follows: Figure 10 As shown, this represents a plane that passes through the upper end face 324 of the second component 320 and extends toward the first component 310. For example, an imaginary plane S is as follows: Figure 10 As shown, it is a plane that passes through the upper end face 324 of the second component 320 and extends vertically toward the first component 310.

[0114] The hemostatic device 100 has a height difference between the first component 310 and the second component 320, with an imaginary plane S as a reference. The upper end face 314 of the first component 310 is configured to be higher than the upper end face 324 of the second component 320 (from the expansion member 110). Therefore, the hemostatic device 100 is configured such that the first front end face 313 and the second front end face 323 are aligned in the height direction of the tube fixing portion 300. Figure 10 The areas opposite each other in the vertical direction (the first front end face 313 and the second front end face 323) are separated by the slit portion 330. Figure 10 The overlapping area in the vertical direction orthogonal to the vertical direction is reduced. Therefore, when the practitioner presses the tube 183 into the tube fixing part 300 (inserts the tube 183 into the tube fixing part 300), the hemostatic device 100, through the external force applied to the tube 183, can deform the first component 310 in the expansion direction of the slit 330, and then deform the second component 320 in the expansion direction of the slit 330 while maintaining the deformation of the first component 310. As a result, the hemostatic device 100 can suppress the force required for the practitioner to insert the tube 183 into the tube fixing part 300 when it is worn on the patient's right hand H1, making it easier for the practitioner to insert the tube 183 into the tube fixing part 300.

[0115] Additionally, the hemostatic device 100 (support component 130) such as Figure 4 , Figure 5 , Figure 10 As shown, a hole 350 is formed between the first component 310 and the second component 320. The hole 350 is as follows... Figure 10 As shown, a through hole is located between the first component 310 and the second component 320, penetrating between the inner surface 130a and the outer surface 130b of the support component 130. Furthermore, the position of the hole 350 is only required to be within... Figure 5 The part located between the first component 310 and the second component 320 in the planar view shown is not particularly limited.

[0116] The support member 130 has a hole 350 between the first member 310 and the second member 320. Thus, with the tube 183 inserted into the tube holding part 340, the hemostatic device 100 applies an external force (towards) the tube 183. Figure 5 The force applied to the tube section 183 in the left and right directions, for example, from... Figure 5 The force of pressing the tube section 183 from the left to the right, from Figure 5 When the force is applied from the right side to the left side of the tube portion 183, a portion of the tube portion 183 enters the hole portion 350, thereby reducing the deformation of the tube portion 183 between the connecting portion K and the tube fixing portion 300, and mitigating the movement away from the outer surface 130b of the support member 130. Therefore, with the tube portion 183 inserted into the tube holding portion 340, even when an external force is applied to the tube portion 183, the hemostatic device 100 can reduce the deformation of the tube portion 183 between the connecting portion K and the tube fixing portion 300, preventing the operator from scraping the deformed tube portion 183. Furthermore, with the tube portion 183 inserted into the tube holding portion 340, when an external force is applied to the tube portion 183 (from the right side to the left side of the tube holding portion 340), the hemostatic device 100 can reduce the deformation of the tube portion 183 between the connecting portion K and the tube fixing portion 300, and prevent the operator from scraping the deformed tube portion 183. Figure 5 When the force is applied to the tube section 183 from the left to the right, a portion of the tube section 183 enters the hole section 350, thereby allowing the tube section 183 to exit... Figure 5 Moving from left to right also prevents the connector portion 181 and the buffer member 182 from sliding away from the tube fixing portion 300. Therefore, with the tube portion 183 inserted into the tube holding portion 340, the hemostatic device 100 applies an external force to the tube portion 183 (from... Figure 5 When the force is applied to the tube portion 183 from the left to the right, the force of the connector portion 181 and the buffer member 182 is reduced. Figure 5 The left-to-right sliding mechanism also prevents the connector 181 and buffer 182 from getting caught on the bed or other parts located around the patient. Furthermore, the hole 350 also functions as a mold release hole during the molding of the first part 310 and the second part 320. Therefore, the hemostatic device 100 can reduce the number of molds required when molding the support member 130, which is integrally formed with the tube fixing part 300, thereby reducing manufacturing costs.

[0117] In addition, the longitudinal width of the hole 350 (hereinafter referred to as "longitudinal width") Figure 5 The length in the vertical direction refers to Figure 10 The length in the left-right direction can be, for example, formed by the width Y2 of the tube holding portion 340. The longitudinal width of the hole portion 350 is preferably the diameter of the tube portion 183. Therefore, with the tube portion 183 inserted into the tube holding portion 340, the hemostatic device 100 applies external force to the tube portion 183 (in... Figure 5When the force applied to the tube 183 in the left-right direction is applied, a portion of the tube 183 can easily enter the hole 350. Furthermore, the width of the hole 350 (hereinafter referred to as "width")... Figure 5 The length in the left-right direction can be, for example, formed by the width Z1 of the first main body 311 or the width Z3 of the second main body 321.

[0118] The first bend 312, as shown Figure 10 As shown, the device has a first curved surface 312a that bends toward the second component 320. The first curved surface 312a is located opposite the second front end surface 323 across the tube holding portion 340. Therefore, when the operator pulls the tube portion 183 away from the tube fixing portion 300 (removes the tube portion 183 from the tube fixing portion 300), the first curved surface 312a serves as a guiding surface to move the tube portion 183 from the tube holding portion 340 toward the slit portion 330. As a result, the hemostatic device 100 can suppress the force required for the operator to remove the tube portion 183 from the tube fixing portion 300 while it is worn on the patient's right hand H1, making it easier for the operator to remove the tube portion 183 from the tube fixing portion 300.

[0119] Second bend 322 Figure 10 As shown, the device has a second curved surface 322a that bends toward the first component 310. When the operator removes the tube portion 183 from the tube fixing portion 300, the hemostatic device 100 moves the tube portion 183 fixed to the tube fixing portion 300 along the first curved surface 312a and / or the second curved surface 322a, thereby making it easier to move toward the slit portion 330. This makes it easier for the operator to remove the tube portion 183 from the tube fixing portion 300.

[0120] The thickness of the front ends of the first curved portion 312 and the second curved portion 322 (i.e., the length X1 of the first front end face 313 that combines the length X2 of the first region 313a and the length X3 of the second region 313b of the first front end face 313, or the length of the second front end face 323. Here, "length" refers to the thickness of the front ends of the first curved portion 312 and the second curved portion 322.) Figure 10 The length of the first front end face 313 in the enlarged view (in the vertical direction) is not particularly limited and can be set to any thickness that minimizes the risk of breakage when the practitioner attaches or detaches the tube 183 relative to the tube fixing part 300, ensuring the tube fixing part 300 is structurally stable. As described above, the tube fixing part 300 is configured such that the first front end face 313 and the second front end face 323 are located in the height direction of the tube fixing part 300 (in the vertical direction). Figure 10 The area between the slit portion 330 in the vertical direction is reduced. As a result, the tube fixing portion 300 can suppress the force required by the practitioner to install or remove the tube portion 183 relative to the tube fixing portion 300, and the front ends of the first bend portion 312 and the second bend portion 322 are designed to be thick.

[0121] However, the length X3 of the second region 313b of the first front end face 313 is preferably smaller than the radius r1 of the tube portion 183. With this configuration, the hemostatic device 100 can reduce the amount of effort required to move the tube portion 183 from the slit portion 330 toward the tube holding portion 340 when the operator inserts the tube portion 183 into the tube holding portion 300 (this represents the product of the external force applied by the operator to the tube portion 183 and the movement of the tube portion 183. The "distance" referred to here is the distance between the first front end face 313 and the second front end face 323 across the slit portion 330). Therefore, the hemostatic device 100 can reduce the force required for the operator to press the tube portion 183 from the slit portion 330 toward the tube holding portion 340, making it easier for the operator to insert the tube portion 183 into the tube holding portion 300.

[0122] The second front end face 323 is as follows Figure 10 As shown, a curved surface 323c is provided at a position corresponding to the first front end face 313, separated by the slit portion 330. By providing the curved surface 323c between the upper end face 324 of the second component 320 adjacent to the slit portion 330 and the second front end face 323, the hemostatic device 100 guides the movement direction of the tube portion 183 toward the curved surface 323c when the tube portion 183 is inserted into the tube fixing portion 300, making it easier for the tube portion 183 held in the tube holding portion 340 to face the slit portion 330. Therefore, the hemostatic device 100 can suppress the force required for the operator to insert the tube portion 183 into the tube fixing portion 300 while it is worn on the patient's right hand H1, making it easier for the operator to insert the tube portion 183 into the tube fixing portion 300.

[0123] In this way, the hemostatic device 100 can suppress the force required by the operator to attach or detach the tube 183 relative to the tube fixation part 300 while it is worn on the patient's right hand H1. Therefore, the hemostatic device 100 can prevent unintentional application of external force to the first puncture site p1, and / or prevent misalignment of the hemostatic device 100 that may occur due to unintentional application of external force to the dilation member 110.

[0124] The pipe fixing part 300 is made of a material that is harder than the material constituting the pipe part 183. Furthermore, the pipe fixing part 300 is as follows: Figure 3As shown, the support member 130 is located on the outer surface 130b of the support member 130, which is made of a material harder than the bands 140, 150, and 160. Therefore, the operator can easily attach and detach the tube portion 183 from the tube fixing portion 300 while the hemostatic instrument 100 is worn on the patient's right hand H1. Furthermore, since the tube fixing portion 300 is made of a material harder than the tube portion 183, the first main body 311 and the second component 320 are less likely to deform under unintentionally applied force, preventing the tube portion 183 held in the tube fixing portion 300 from unintentionally detaching from it. Additionally, since the tube fixing portion 300 is located on the support member 130, which is made of a hard material, misalignment of the hemostatic instrument 100 that may occur due to unintentionally applied external force to the expansion member 110 connected to the support member 130 can be prevented. Furthermore, as... Figure 3 As shown, when the tube fixing part 300 is located outside the expansion member 110 on the outer surface 130b of the support member 130, it is possible to more reliably prevent the hemostatic device 100 from being misaligned due to unintentionally applying external force to the expansion member 110 connected to the support member 130.

[0125] Furthermore, the forming method of the tube fixing part 300 is not particularly limited, such as Figure 3 As shown, it can be integrally formed with the support member 130 and can be made of the same constituent material as the support member 130.

[0126] Furthermore, the tube fixing part 300 is not limited in its position as long as it is located in a position where the tube part 183 can be easily attached to or detached from the tube fixing part 300 when the tube is worn on the patient's right hand H1. Therefore, it can be located on any of the straps 140, 150, and 160, as long as it is located on the fixing part 120 used to fix the expansion part 110.

[0127] Pipe fixing part 300 Figure 3As shown, the first curved region 134a of the support member 130 is located on the outer side compared to the expansion member 110. The hemostatic device 100 is worn in such a way that the first curved region 134a of the support member 130 does not come into close contact with the surface of the patient's right hand H1. Therefore, the practitioner can hold the support member 130 of the hemostatic device 100 worn on the patient's right hand H1 by pinching it with two fingers when fixing the tube 183 to the tube fixing part 300. The practitioner can insert the tube 183 into the tube fixing part 300 with one finger located on the outer surface 130b side of the support member 130, while the other finger located on the inner surface 130a side of the support member 130 absorbs the external force applied to the tube 183. Thus, the practitioner can fix the tube 183 to the tube fixing part 300 without applying unintentional external force to the support member 130. Furthermore, by holding the support member 130 of the hemostatic device 100, which is worn on the patient's right hand H1, while the tube 183 is fixed to the tube fixing part 300, the practitioner can more reliably prevent the support member 130 from tilting due to external forces applied to the tube 183. Therefore, when the hemostatic device 100 is worn on the patient's right hand H1 and the practitioner inserts the tube 183 into the tube fixing part 300, it can prevent unintentional application of external force to the first puncture site p1, and / or prevent misalignment of the hemostatic device 100 that may occur due to unintentional application of external force to the dilation member 110 by the transmission of external force to the support member 130.

[0128] Pipe fixing part 300 Figure 3 As shown, it is positioned opposite the third belt 160, separated by the expansion member 110. Figure 3 and Figure 4 As shown, the connection portion K between the dilator 110 and the tube 183 is positioned on the side of the third band 160 for ease of operation of the injection component 180 when the operator adjusts the fluid volume of the dilator 110. Therefore, by positioning the tube fixing portion 300 opposite to the third band 160, any excess tube 183 that may occur between the connection portion K of the tube 183 fixed to the tube fixing portion 300 and the tube fixing portion 300 can be reduced. Consequently, when the patient moves their right hand H1, etc., the wobbling of the end of the tube 183 on the connector portion 181 side can be suppressed, and unintentional external force applied to the dilator 110 can be prevented. Furthermore, when the tube 183 is fixed to the tube fixing portion 300, the radius of curvature formed by the tube 183 located between the connection portion K and the tube fixing portion 300 increases, thus preventing the tube 183 from twisting.

[0129] <Examples of the use of hemostatic instruments>

[0130] Next, refer to Figures 12-16 This section describes an example of using hemostatic device 100.

[0131] In the usage example, the order of use of the hemostatic instrument 100 is explained when stopping bleeding at the first puncture site p1 formed on the patient's right hand H1.

[0132] Figure 12 The image shows the state of various procedures being performed and terminated by inserting the sheath of the guide 200 into the first puncture site p1.

[0133] When the practitioner places the hemostatic instrument 100 on the patient's right hand H1, if Figure 12 As shown, the support member 130 is positioned so that it overlaps the back of the patient's right hand H1. At this time, the operator visually confirms the position of the marker 115 positioned on the dilator 110 and positions the marker 115 on the first puncture site p1, thereby properly positioning the dilator 110 at the first puncture site p1.

[0134] Furthermore, after the procedure using the guide device 200, before attaching the hemostatic device 100 to the patient's right hand H1, the surgeon can also pull out a portion of the sheath of the guide device 200 from the first puncture site p1 formed in the patient's right hand H1. For example, the surgeon can pull the sheath of the guide device 200 about 2-3 cm towards the surgeon's hand while the sheath is still inserted in blood vessel B, and then begin attaching the hemostatic device 100.

[0135] The practitioner, such as Figure 12 , Figure 13 As shown, the first band 140 and the second band 150 are wrapped around the outer periphery of the patient's right hand H1. The practitioner secures the band by placing the fourth fixation point 174 (see reference) on the inner surface of the second band 150. Figure 2 ) and the first fixing part 171 disposed on the outer surface of the first belt body 140 (refer to Figure 1 The first belt body 140 and the second belt body 150 can be connected by means of the fixed parts 171 and 174.

[0136] The practitioner, such as Figure 14 As shown, the third band 160 is passed through the interphalangeal portion fb located between the thumb and index finger of the patient's right hand H1, and a portion of the third band 160 is positioned on the palmar side of the patient's right hand H1. At this time, the practitioner fixes the fifth fixation point 175 (see reference) on the inner surface of the third band 160. Figure 2 ) and the second fixing part 172 disposed on the outer surface of the second belt 150 (refer to Figure 1 The second belt 150 and the third belt 160 can be connected by means of the fixed parts 172 and 175.

[0137] The operator injects air into the dilator 110 while the syringe is connected to the connector 181, thereby dilating the dilator 110. Hemostatic device 100, such as... Figure 15 , Figure 16 As shown, if the dilation member 110 dilates, the dilation member 110 applies pressure to the first puncture site p1 of the patient's right hand H1.

[0138] The practitioner fixes tube 183 to tube fixing part 300 (see reference). Figures 3-5 The tube fixing part 300 of this embodiment can suppress the force required by the practitioner to fix the tube part 183 to the tube fixing part 300. In addition, by holding the support member 130 of the hemostatic device 100 worn on the patient's right hand H1 while fixing the tube part 183 to the tube fixing part 300, the practitioner can prevent the support member 130 from tilting due to the external force applied to the tube part 183 by the practitioner. Therefore, the hemostatic device 100 can prevent unintentional application of external force to the first puncture site p1, and / or prevent misalignment of the hemostatic device 100 that may occur due to unintentional application of external force to the dilation member 110.

[0139] Following the above sequence, the practitioner can use hemostatic instrument 100 to stop the bleeding at the first puncture site p1 formed on the patient's right hand H1.

[0140] Furthermore, when using the hemostatic instrument 100 to stop bleeding at the second puncture site p2 on the patient's right hand H1, the practitioner, while wrapping the bands 140 and 150 around the patient's right hand H1, slides the bands 140 and 150 around the center point R. By wrapping the sliding bands 140 and 150 around the patient's right hand H1 at a position closer to the forearm A (proximal side) than the first puncture site p1, the practitioner can stop bleeding at the second puncture site p2 on the patient's right hand H1.

[0141] The hemostatic device 100 of this embodiment includes: an expansion member 110 configured to compress the hemostatic site of a patient's limb; a fixing member 120 configured to fix the expansion member 110 to the patient's limb; an injection member 180 comprising a connector portion 181 configured to inject fluid for expanding the expansion member 110, and a tube portion 183 connecting the connector portion 181 to the inner cavity 113 of the expansion member 110; and a tube fixing portion 300 located at... The fixing member 120 is configured to fix the tube portion 183. The tube fixing member 300 includes: a first member 310; a second member 320 located on the side of the expansion member 110 and opposite to the first member 310; a slit portion 330 formed between the first member 310 and the second member 320 and configured to insert the tube portion 183; and a tube holding portion 340 surrounded by the first member 310, the second member 320 and the slit portion 330 and configured to hold the tube portion 183. 3. The first component 310 has a first main body portion 311, a first curved portion 312 bent toward the second component 320, and a first front end face 313 located at the front end of the first curved portion 312. The second component 320 has a second main body portion 321, a second curved portion 322 bent toward the first component 310, and a second front end face 323 located at the front end of the second curved portion 322 and opposite to the first front end face 313 across a slit portion 330. A portion of the first component 310 is compared to the second component 320. The first front end face 313 is located away from the expansion member 110 in a direction perpendicular to the imaginary plane S formed relative to the slit portion 330. It has a first region 313a that is not opposite to the second front end face 323 through the slit portion 330, and a second region 313b that is opposite to the second front end face 323 through the slit portion 330. The first curved portion 312 has a first curved surface 312a that is curved toward the second member 320. The first curved surface 312a is opposite to the second front end face 323 through the tube holding portion 340.

[0142] The hemostatic device 100 configured as described above reduces the area where the first front end face 313 and the second front end face 323 face each other across the slit portion 330 by providing a height difference between the first component 310 and the second component 320. Therefore, the hemostatic device 100 can suppress the force required for the operator to insert the tube portion 183 into the tube fixing portion 300 while it is worn on the patient's right hand H1. Furthermore, the first curved surface 312a is located opposite the second front end face 323 across the tube holding portion 340. Therefore, when the operator pulls the tube portion 183 away from the tube fixing portion 300 (removes the tube portion 183 from the tube fixing portion 300), the hemostatic device 100 can use the first curved surface 312a as a guiding surface to move the tube portion 183 from the tube holding portion 340 toward the slit portion 330. Therefore, the hemostatic device 100 can suppress the force required for the operator to remove the tube 183 from the tube fixing part 300 while it is worn on the patient's right hand H1. Therefore, the hemostatic device 100 can prevent unintentional external force from being applied to the puncture sites p1, p2, and / or prevent misalignment of the hemostatic device 100 that may occur due to unintentional external force applied to the dilation member 110.

[0143] Additionally, the fixing member 120 has a support member 130 to which the expansion member 110 is fixed, and a belt (belt 140, 150, 160) configured to be connected to the support member 130. The support member 130 is made of a material harder than the material constituting the belt, and the tube fixing part 300 is made of a material harder than the material constituting the tube part 183, and is located on the surface (outer surface 130b) of the support member 130.

[0144] With the hemostatic device 100 configured as described above, the operator can easily attach and detach the tube portion 183 from the tube fixing portion 300 while the hemostatic device 100 is worn on the patient's right hand H1. Furthermore, since the tube fixing portion 300 is made of a material harder than the tube portion 183, the first main body 311 and the second component 320 are less likely to deform under unintentionally applied force, preventing the tube portion 183 held in the tube fixing portion 300 from unintentionally detaching from it. Additionally, since the tube fixing portion 300 is provided on the support member 130 made of a rigid material, misalignment of the hemostatic device 100 that may occur due to unintentionally applied external force to the expansion member 110 connected to the support member 130 can be prevented.

[0145] Additionally, the support member 130 has a first bending region 134a that bends away from the expansion member 110, and the tube fixing part 300 is located in the first bending region 134a, which is located on the outside compared to the expansion member 110.

[0146] In the hemostatic device 100 constructed as described above, the first curved region 134a of the support member 130 is fitted in a manner that avoids close contact with the surface of the patient's right hand H1. Therefore, when the practitioner fixes the tube 183 to the tube fixing part 300, by pinching the support member 130 of the hemostatic device 100 fitted to the patient's right hand H1, the practitioner's fingers can absorb the external force applied to the tube 183. Thus, the practitioner can fix the tube 183 to the tube fixing part 300 without applying unintentional external force to the support member 130. Furthermore, by pinching the support member 130 of the hemostatic device 100 fitted to the patient's right hand H1 when fixing the tube 183 to the tube fixing part 300, the practitioner can more reliably prevent the support member 130 from tilting due to the external force applied to the tube 183 by the practitioner. Therefore, when the hemostatic device 100 is worn on the patient's right hand H1 and the operator inserts the tube 183 into the tube fixing part 300, it can prevent unintentional application of external force to the puncture sites p1 and p2, and / or prevent misalignment of the hemostatic device 100 that may occur due to unintentional application of external force to the dilation part 110 caused by the external force being transmitted to the support part 130.

[0147] Additionally, the band includes a first band 140 extending from the support member 130 in a first direction, a second band 150 extending from the support member 130 in a second direction different from the first direction, and a third band 160 configured to be disposed between the patient's fingers and extending from the support member 130 in a third direction different from the first and second directions. The connection portion K between the expansion member 110 and the tube portion 183 is located on the side of the third band 160, and the tube fixing portion 300 is located on the surface (outer surface 130b) of the support member 130 that is opposite to the third band 160 across the expansion member 110.

[0148] The hemostatic device 100 constructed as described above can reduce the excess tube portion 183 that may occur between the connecting portion K of the tube portion 183 fixed to the tube fixing portion 300 and the tube fixing portion 300. Furthermore, when the tube portion 183 is fixed to the tube fixing portion 300, it can prevent the tube portion 183 from twisting between the connecting portion K and the tube fixing portion 300.

[0149] In addition, the length X3 of the second region 313b of the first front end face 313 is less than the radius r1 of the tube 183.

[0150] According to the hemostatic device 100 configured as described above, when the operator inserts the tube portion 183 into the tube holding portion 300, the effort required to move the tube portion 183 from the slit portion 330 toward the tube holding portion 340 is reduced. Therefore, the hemostatic device 100 can reduce the force required for the operator to press the tube portion 183 from the slit portion 330 toward the tube holding portion 340, making it easier for the operator to insert the tube portion 183 into the tube holding portion 300. Thus, the hemostatic device 100 can prevent unintentional application of external force to the puncture sites p1 and p2, and / or prevent misalignment of the hemostatic device 100 that may occur due to unintentional application of external force to the dilation member 110.

[0151] In addition, the second front end surface 323 has a curved surface 323c at a position corresponding to the first front end surface 313 across the slit portion 330.

[0152] According to the hemostatic device 100 configured as described above, when the operator inserts the tube portion 183 into the tube fixing portion 300, the hemostatic device 100 guides the movement direction of the tube portion 183 towards the curved surface 323c, making it easier to orient the tube portion 183 held in the tube holding portion 340 toward the slit portion 330. Therefore, the hemostatic device 100 can suppress the force required for the operator to insert the tube portion 183 into the tube fixing portion 300 while it is worn on the patient's right hand H1. Thus, the hemostatic device 100 can prevent unintentional application of external force to the puncture sites p1 and p2, and / or prevent misalignment of the hemostatic device 100 that may occur due to unintentional application of external force to the dilation member 110.

[0153] Next, variations of the hemostatic device of the present invention will be described. In the description of the variations, the description of the components and the order of use of the hemostatic device already described in the description of the foregoing embodiments will be appropriately omitted. In addition, the contents not specifically described in each variation can be set to be the same as those in the foregoing embodiments.

[0154] <Variation Example>

[0155] Figure 17 A portion of the modified hemostatic device 100A is shown in enlarged form.

[0156] like Figure 17 As shown, the tube fixing part 300A of the modified hemostatic device 100A has a first component 310A and a second component 320A. Furthermore, if... Figure 17 As shown in the enlarged diagram of the tube fixing part 300A, the width ZA2 of the first front end face 313A is smaller than the width ZA1 of the first main body part, and the width ZA4 of the second front end face 323A is smaller than the width ZA3 of the second main body part.

[0157] The hemostatic device 100A configured as described above increases the area of ​​the tube fixing portion 300A relative to the support member 130 and shortens the width of the first front end face 313A and the second front end face 323A forming the slit portion 330. Therefore, the hemostatic device 100A ensures the strength of the tube fixing portion 300A and reduces the force required for the operator to attach or detach the tube portion 183 relative to the tube fixing portion 300A when it is worn on the patient's right hand H1. Therefore, the hemostatic device 100A prevents unintentional application of external force to the puncture sites p1 and p2, and / or prevents misalignment of the hemostatic device 100A that may occur due to unintentional application of external force to the dilation member 110. Furthermore, the hemostatic device 100A also improves the strength of the tube fixing portion 300A.

[0158] The above describes the hemostatic device of the present invention through embodiments, but the present invention is not limited to the contents described in the specification and can be appropriately modified based on the claims.

[0159] In the description of the embodiments, a hemostatic device is illustrated for stopping bleeding at puncture sites formed on the back of the right hand and puncture sites formed on the forearm. However, the hemostatic device is configured to stop bleeding at puncture sites formed on the back of the left hand, puncture sites formed on the palm of either hand, and puncture sites formed on the patient's feet (e.g., the instep, sole, etc.).

[0160] The shape and size of each part of a hemostatic device are not particularly limited, as long as an expansion component can be installed at the site where hemostasis is required, and can be appropriately modified.

[0161] This application is based on Japanese Patent Application No. 2021-082265, filed on May 14, 2021, the disclosure of which is incorporated herein by reference in its entirety.
