[Modes for carrying out the invention]

[0017] The embodiments of this disclosure will be described in detail below with reference to the drawings.

[0018] First, the hemostatic device 1 according to the reference example will be described with reference to Figures 1 to 6. As shown in Figures 1 to 2, the hemostatic device 1 according to the reference example includes a support member 2 configured to cover the puncture site formed on the patient, a pressing member 3 configured to compress the puncture site and held by the support member 2, and a belt member 4 configured to fix the support member 2 to the puncture site.

[0019] The support member 2 has a plate member 5 that is translucent to visible light, and an edge portion 6 that is provided around the entire circumference along the outer edge of the plate member 5. The plate member 5 is made of a harder material than the edge portion 6 and the belt member 4. The pressing member 3 is held on the back surface 2a of the support member 2. The pressing member 3 is composed of a balloon 7, and the hemostatic device 1 has an inflation port 8 configured to introduce gas into the balloon 7. The balloon 7 can be inflated and compress the puncture site by connecting a gas delivery device, such as a syringe, to the inflation port 8 and introducing gas into the balloon 7 through the inflation port 8. The inflation port 8 is integrally connected to the surface 2b of the support member 2 (plate member 5). The inflation port 8 also protrudes from the plate member 5 toward the surface side. The support member 2 is positioned so that its back surface 2a faces the back of the patient's hand.

[0020] The belt member 4 includes a first belt portion 4a that extends from the edge 6 of the support member 2 and is positioned between the fingers of the patient's hand, a second belt portion 4b that extends from the edge 6 of the support member 2 at a different position from the first belt portion 4a, and a third belt portion 4c that extends from the edge 6 of the support member 2 at a position opposite the second belt portion 4b with the pressing member 3 in between.

[0021] More specifically, the first belt portion 4a is configured to be positioned between the thumb and index finger of the right hand, the second belt portion 4b is configured to extend from the support member 2 toward the thumb, and the third belt portion 4c material 4 is configured to extend from the support member 2 toward the little finger. The second belt portion 4b is longer than the third belt portion 4c. The back surface of the second belt portion 4b is configured with a female surface that can be attached to and detached from the male surface (third belt male surface 9) of the hook-and-loop fastener provided on the surface of the third belt portion 4c. The back surface of the first belt portion 4a is configured with a female surface that can be attached to and detached from the male surface (second belt male surface 10) of the hook-and-loop fastener provided on the surface of the second belt portion 4b.

[0022] The pressing member 3 is positioned on the back surface of the plate member 5, towards the thumb side, and is configured to compress the puncture site to the distal radial artery.

[0023] By wrapping the second belt portion 4b around the right wrist and attaching it to the third belt male surface 9, and then passing the first belt portion 4a between the thumb and index finger and wrapping it around and attaching it to the second belt male surface 10, the support member 2 can be fixed to the puncture site in the distal radial artery, as shown in Figures 3 and 4. Then, the balloon 7 can be inflated and the puncture site compressed to stop bleeding.

[0024] Next, let's consider the case where the right-hand hemostatic device 1 in this example is used to stop bleeding at a puncture site in the distal radial artery of the left hand. When the hemostatic device 1 is attached to the left hand, it will look like Figures 5 and 6, and in this case, several problems become apparent. The first problem is that when the pressing member 3 is placed on the puncture site, the plate member 5 of the support member 2 protrudes from the wrist towards the thumb, creating a large gap between the wrist and the support member 2, making it impossible to securely fix the hemostatic device 1 to the wrist. The second problem is that the first belt portion 4a is positioned off-center from the space between the thumb and index finger, making it impossible to position it between the thumb and index finger. And the third problem is that because the second belt male surface 10 is short, even if the first belt is wrapped around between the thumb and index finger, it may not be possible to fix it to the second belt portion 4b.

[0025] In order to make the hemostatic device 1 described above easier to use not only with the right hand but also with the left hand, or to make it easier to use not only on the hand but also on the foot, for example, on both the right and left sides, it is necessary to have a means that can solve at least one of the three problems described above. Therefore, the hemostatic device 1 according to one embodiment of this disclosure includes such a means.

[0026] As shown in Figures 7 to 8, a hemostatic device 1 according to one embodiment of the present disclosure includes a support member 2 configured to cover a puncture site formed on a patient, a pressing member 3 configured to compress the puncture site and held by the support member 2, and a belt member 4 configured to fix the support member 2 to the puncture site.

[0027] The belt member 4 includes a first belt portion 4a that extends from the support member 2 and is positioned between the patient's fingers, a second belt portion 4b that extends from the support member 2 at a different position from the first belt portion 4a, and a third belt portion 4c that extends from the support member 2 at a position opposite the second belt portion 4b with the pressing member 3 in between.

[0028] The support member 2 has a first region R1 where the pressing member 3 is located, a second region R2 configured to be located between the first region R1 and the second belt portion 4b, a third region R3 configured to be located between the first region R1 and the third belt portion 4c, and a deformation region R4 located between the first region R1 and the second region R2 and the third region R3, respectively.

[0029] The first region R1, the second region R2, and the third region R3 are formed from a material harder than the belt member 4, and the deformable region R4 is bendable so as to displace (rotate) the second region R2 and the third region R3 toward the pressing member 3, as shown in Figures 9 to 10.

[0030] In the embodiments shown in Figures 9 and 10, the support member 2 has a plate member 5 integrally comprising a first region R1, a second region R2, a third region R3, and a deformation region R4, the deformation region R4 being formed by a groove 11. The plate member 5 is translucent to visible light. The pressing member 3 is located and held on the back surface of the first region R1 of the plate member 5. The pressing member 3 is located in the center of the first region R1 when viewed from below.

[0031] For the sake of explanation, the surface 2b of the support member 2 is also referred to as the top surface, and the back surface 2a of the support member 2 is also referred to as the bottom surface. Furthermore, in a top view, the direction from the second belt portion 4b toward the third belt portion 4c is also referred to as the right side, the opposite side is also referred to as the left side, and the direction from the support member 2 toward the first belt portion 4a is also referred to as the front side.

[0032] The pressing member 3 is composed of a balloon 7, and the hemostatic device 1 has an inflation port 8 configured to introduce gas into the balloon 7. The inflation port 8 is located in the center of the left-right distance between adjacent deformation regions R4. The balloon 7 can be inflated and compress the puncture site by connecting a gas delivery member, such as a syringe, to the inflation port 8 and introducing gas into the balloon 7 through the inflation port 8. The inflation port 8 is integrally connected to the surface 2b of the first region R1 of the support member 2 (plate member 5). The inflation port 8 also protrudes from the first region R1 of the support member 2 (plate member 5) toward the surface 2b.

[0033] As shown in Figure 8, the first belt portion 4a is configured to be located between adjacent deformation regions (extension lines). Therefore, in the plan view of Figure 8, the first belt portion 4a extends from the first region R1 in the direction away from the pressing member 3. Furthermore, the first belt portion 4a is configured to be detachable from the support member 2 between adjacent deformation regions R4 (see the dashed lines in Figures 7 and 8), and its position relative to the support member 2 can be changed from the first region R1 toward the second region R2 or the third region R3 (i.e., in the left-right direction). More specifically, the support member 2 has a detachable portion 12 to which the first belt portion 4a can be attached, and by changing the attachment position of the first belt portion 4a to the detachable portion 12, its position relative to the support member 2 can be changed from the first region R1 toward the second region R2 or the third region R3. The detachable portion 12 is made of the male side of a hook-and-loop fastener. The first belt portion 4a has a detachable end portion 13 that can be attached to and detached from the attachment portion 12 of the support member 2.

[0034] The second belt portion 4b is longer in the left-right direction than the third belt portion 4c. The back surface of the second belt portion 4b is composed of a female surface that can be attached to and detached from the male surface (third belt male surface 9) of the hook-and-loop fastener provided on the surface of the third belt portion 4c. The back surface of the first belt portion 4a is composed of a female surface that can be attached to and detached from the male surface (second belt male surface 10) of the hook-and-loop fastener provided on the surface of the second belt portion 4b. The second belt male surface 10 is provided along almost the entire length of the second belt portion 4b.

[0035] In this embodiment, the hemostatic device 1 is configured for hemostasis of puncture sites in the distal radial artery formed on the backs of the right and left hands. As shown in Figure 11, when the hemostatic device 1 is used on the right hand, by attaching the detachable end 13 of the first belt portion 4a to the right side in a top view relative to the detachable portion 12, the hemostatic device 1 can be positioned appropriately between the thumb and index finger with the pressing member 3 placed on the puncture site, and the pressing member 3 can be fixed to the puncture site without shifting position. Therefore, the hemostatic device 1 can suitably compress the puncture site located on the right hand with the pressing member 3. At this time, the support member 2 is positioned so that its back surface 2a faces the back of the patient's hand. When wrapping the second belt portion 4b around the wrist, the deformable area R4 on the left side in a top view can bend along the wrist, so the second belt portion 4b can be wrapped around the wrist to fit and fixed to the third belt. Furthermore, since the hemostatic device 1 is configured such that the first belt portion 4a is positioned between adjacent deformable regions R4, it is possible to prevent deformation caused by bending of the deformable region R4 from being transmitted to the first belt portion 4a.

[0036] On the other hand, as shown in Figure 12, when the hemostatic device 1 is used on the left hand, by attaching the detachable end 13 of the first belt portion 4a to the left side in a top view relative to the detachable portion 12, the hemostatic device 1 can be positioned appropriately between the thumb and index finger with the pressing member 3 placed on the puncture site, and the pressing member 3 can be fixed to the puncture site without shifting position. Therefore, the hemostatic device 1 can suitably compress the puncture site located on the left hand with the pressing member 3. In this case as well, the support member 2 is positioned so that its back surface 2a faces the back of the patient's hand. When wrapping the third belt portion 4c around the wrist, the deformable area R4 on the right side in a top view bends along the wrist, allowing the third belt portion 4c to be wrapped around the wrist to fit and be fixed to the second belt. Furthermore, since the hemostatic device 1 is configured so that the first belt portion 4a is positioned between adjacent deformable areas R4, deformation due to bending of the deformable area R4 can be prevented from being transmitted to the first belt portion 4a. Furthermore, since the second belt male surface 10 is provided over almost the entire length of the second belt, the first belt portion 4a wrapped around the hand can be fixed to the second belt male surface 10. Therefore, with the hemostatic device 1 of this embodiment, bleeding can be effectively stopped at both the puncture site on the right hand and the puncture site on the left hand.

[0037] Furthermore, the configuration of this embodiment can be applied not only to the hands but also to hemostatic devices 1 that can be used on both the left and right sides, such as the feet.

[0038] As shown in Figure 13, in this embodiment, the width between adjacent deformation regions R4 is configured to narrow from the first belt portion 4a side toward the base end side. Therefore, the length L1 of the side of the first belt portion 4a in the first region R1 is longer than the length L2 of the opposite side. In the embodiment of Figure 13, the length L1 of the side of the first belt portion 4a is configured to be longer than the length L2 of the opposite side, resulting in a trapezoidal shape. Therefore, as described above, when worn on the wrists of the right and left hands, the deformation region R4 can be bent to better fit the shape of the back of the hand from the base of the thumb toward the wrist. Thus, loosening of the belt member 4 relative to the wrist can be suppressed. For example, the length L1 of the side of the first belt portion 4a can be set to about 2.0 times the width W1 (see Figure 14) of the pressing member 3 in the left-right direction, and the length L2 of the opposite side can be set to about 1.5 times the width W1 of the pressing member 3 in the left-right direction.

[0039] As shown in Figure 14, it is preferable that the width W2 of the attachment / detachment part 12 (male side) in the left-right direction is greater than the width W1 of the pressing member 3 in the left-right direction. This allows the position of the first belt portion 4a to be appropriately adjusted in the left-right direction when the surgeon attaches the hemostatic device 1 to a puncture site located on the right or left hand. For example, it is more preferable that the width W2 of the attachment / detachment part 12 (male side) in the left-right direction is 1.5 to 2.0 times the width W1 of the pressing member 3 in the left-right direction (e.g., 4.5 to 6.0 cm). Furthermore, from the viewpoint of stabilizing the fixation of the first belt portion 4a at the attachment / detachment part 12, it is preferable that the width W2 of the attachment / detachment part 12 in the left-right direction is less than or equal to the length L1 of the side of the first belt portion 4a in the first region R1.

[0040] The width W3 of the first belt portion 4a is preferably half (1 / 2) or more of the length L1 of the side of the first belt portion 4a in the first region R1. With this configuration, when the first belt portion 4a is fixed, at least a part of the first belt portion 4a can be positioned on the center line of the pressing member 3. As a result, when the hemostatic device 1 is attached, the wrapping force of the first belt portion 4a is appropriately transmitted to the pressing member 3 via the first region R1, so that the pressing member 3 can be properly fixed to the puncture site. As a result, misalignment of the pressing member 3 relative to the puncture site can be suppressed.

[0041] It is preferable that the width W3 of the first belt portion 4a increases at the detachable end portion 13. With this configuration, the fixing strength between the detachable end portion 13 and the detachable portion 12 is increased, making it less likely to come off during use.

[0042] It is preferable that the inflation port 8 is located in the center of the space between adjacent deformation regions R4 (i.e., the lateral distance from the inflation port 8 to the deformation region R4 on the right is equal to the lateral distance from the inflation port 8 to the deformation region R4 on the left). With this configuration, the influence of the inflation port 8 on the bending deformation of the deformation region R4 can be suppressed, making it easier to achieve easy bending deformation.

[0043] The pressing member 3 (balloon 7) is preferably positioned in the center of the first region R1 when viewed from the bottom. With this configuration, as described above, it is easier to make the hemostatic effect the same for both the right and left hands when used on the right and left hands.

[0044] When the hemostatic device 1 is used on the right and left hands as described above, the length of the second belt male surface 10 is preferably 12 to 18 cm. Furthermore, the length of the second belt portion 4b is preferably at least 2 / 3 of the circumference of the wrist, based on the wrist circumference of an average person. With this configuration, even when used on the left hand as described above, the length of the second belt portion 4b is sufficient, making it possible to attach the hemostatic device 1 to the left hand.

[0045] The grooves 11 forming the deformation region R4 are preferably continuous grooves 11. However, as shown in Figure 15, the deformation region R4 may also be composed of intermittent grooves 11. Such a configuration improves the visibility of the grooves 11 (deformation region R4). The grooves 11 may be provided on both the surface 2b side and the back surface 2a side, as shown in Figures 9 to 10, or on only one of them.

[0046] By configuring the deformation region R4 with grooves 11, it is possible to easily bend the deformation region R4 at the intended position with a simple structure. Furthermore, even if the plate member 5 becomes slightly cloudy when bent due to its material, the grooves 11 reduce the area of ​​cloudiness, thus maintaining visibility.

[0047] As shown in Figure 16, the deformation region R4 is not limited to the groove 11, but may also be composed of a hinge member 14 connecting the first region R1, the second region R2, and the third region R3, which are formed separately. This configuration also makes it easier to bend the deformation region R4.

[0048] As shown in Figure 17, the deformation region R4 may be composed of a flexible member 15 (for example, cloth or a resin material such as polyvinyl chloride) that connects the first region R1, the second region R2, and the third region R3, respectively. This configuration also makes it easier to bend the deformation region R4.

[0049] As shown in Figure 18, each deformation region R4 may consist of a completely separated cut portion 16 and groove portions 17 provided on both sides of the cut portion 16 in the front-rear direction. The shape of the cut portion 16 can be curved or bent, and with such a configuration, when using a large pressing member 3, it is possible to obtain effects such as being able to position the pressing member 3 right up to the edge of the cut portion 16.

[0050] As shown in Figure 18, it is preferable that the support member 2 has an edge portion 6 that extends around the entire circumference of the outer edge of the plate member 5. With this configuration, by making the edge portion 6 out of a flexible member 15, the outer edge of the support member 2 is less likely to dig into the hand, and as a result, pain can be suppressed. In addition, having an edge portion 6 makes it easier to maintain the integrity of the plate member 5. The edge portion 6 may be made to have the same or higher rigidity as the plate member 5. When an edge portion 6 is included, the deformation region R4 may be made out of a groove 11 that can be broken by bending.

[0051] As shown in Figure 19, the support member 2 may be configured without an edge portion 6, with the plate member 5 directly connected to the belt member 4.

[0052] As shown in Figure 20, the detachable part 12 has a mark 18 that distinguishes the first part 12a and the second part 12b, which can be selectively attached to and detached from the first belt part 4a. The mark 18 can be made up of a notch, for example, as shown in Figure 20. The size of the notch can be set as appropriate. Also, the shape of the notch is not limited to a V shape as shown, but may be U-shaped. Alternatively, instead of a notch, it may be made up of linear printing, linear fusion marks, or letters, as shown in Figure 21. The mark 18 makes it easier for the user to recognize the distinction between the attachment positions.

[0053] As shown in Figure 22, a hook may be used instead of a hook-and-loop fastener. That is, the fastening portion 12 may be made up of the hook's holes 19a, and the fastening end 13 may be made up of the hook's prongs 19b. Conversely, the fastening portion 12 may be made up of the hook's prongs 19b, and the fastening end 13 may be made up of the hook's holes 19a.

[0054] As shown in Figure 23, a button 20a may be used instead of a hook-and-loop fastener. That is, the fastening portion 12 may be made of a button 20a and the fastening end 13 may be made of a slit 20b. Conversely, the fastening portion 12 may be made of a slit 20b and the fastening end 13 may be made of a button 20a.

[0055] As shown in Figure 24, the first belt portion 4a may be composed of two belt members 4. In the modified example shown in Figure 24, the first belt portion 4a has a first belt portion 4a located on the second region R2 side and a second first belt portion 4a located on the third region R3 side. In this case, both first belt portions 4a may be integrally (non-detachable) attached to the support member 2. With this configuration, when the surgeon attaches the hemostatic device 1 to the puncture site on the right or left hand, the effort required for the surgeon to attach the detachable end 13 of the first belt portion 4a to the detachable part 12 can be reduced. In addition, the loss of the first belt portion 4a can be suppressed.

[0056] As shown in Figure 25, the hemostatic device 1 may have an inflation tube 21 with one end connected to the balloon 7 and an inflation balloon 22 connected to the other end of the inflation tube 21, instead of an inflation port 8. With such a configuration, the influence on the bending deformation of the deformation region R4 can be suppressed and bending deformation can be easily performed. In this case, the balloon 7 can be inflated by connecting a gas delivery device such as a syringe to a connector (not shown) provided on the inflation balloon 22 and sending gas to the balloon 7 through the inflation tube 21, thereby compressing the puncture site. The inflation balloon 22 can signal an abnormality by deflating if gas leakage occurs in the balloon 7 due to damage or other reasons.

[0057] As shown in Figure 26, the second belt portion 4b may be configured to be detachable from the support member 2. Similarly, the third belt portion 4c may be configured to be detachable from the support member 2. With such a configuration, the operator can easily adjust the lengths of the second belt portion 4b and the third belt portion 4c to suit the patient. As for the attachment / detachment mechanism, hooks, buttons, or fasteners as described above can be used.
