[0041] As described in the background technology, in the prior art, after vascular intervention surgery, it is necessary to stop bleeding of the blood vessels, usually using vascular sutures, vascular closures or manual compression to stop bleeding of the blood vessels. However, vascular sutures and vascular closures require professional and skilled doctors to operate the instruments to perform vascular suture surgery, which causes secondary trauma to the patient, and the precision requirements of the instruments are extremely high. The instruments are expensive, and the economic cost to the patient is high; manual compression hemostasis will produce positive compression on the blood vessels and significantly affect the blood flow, which is very likely to cause vascular complications.

[0042] In order to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides a hemostatic device, please refer to Figures 1 to 13 The hemostatic device is used to stop bleeding at a bleeding hole 3 on the epidermis. The hemostatic device includes a plurality of adhesive members 1 and a gathering member 2. The plurality of adhesive members 1 are arranged around the bleeding hole 3. Each adhesive member 1 includes a patch 110 that can be bonded to the epidermis near the bleeding hole 3 and a convex portion 120 arranged at one end of the patch 110 close to the bleeding hole 3. The convex portion 120 is arranged on the side of the patch 110 away from the epidermis. The convex portion 120 has an outer side surface 121 away from the bleeding hole 3. The adhesive member 1 has a dispersed state of being bonded to the epidermis near the bleeding hole 3, and a gathered state of driving the epidermis bonded thereto to gather toward the bleeding hole 3 to close the bleeding hole 3; the gathering member 2 is arranged around the bleeding hole 3 and can be connected to each convex portion 120. The gathering member 2 can apply an external force directed to the bleeding hole 3 to the convex portion 120 to switch the adhesive member 1 from the dispersed state to the gathered state.

[0043] The hemostatic device provided by the embodiment of the present invention, compared with the prior art, includes a plurality of adhesive members 1 and a gathering member 2. The adhesive member 1 includes a patch 110 that can be adhered to the epidermis near the bleeding port 3 and a convex portion 120 arranged at one end of the patch 110 near the bleeding port 3. The gathering member 2 is arranged around the bleeding port 3 and can be connected to each convex portion 120. The gathering member 2 can apply an external force directed to the bleeding port 3 to the convex portion 120 to switch the adhesive member 1 from a dispersed state to a gathered state. During this process, each adhesive member 1 can drive the epidermis adhered thereto to gather toward the bleeding port 3, so that the hemostatic device of the present invention can close the bleeding port 3 by a lateral force directed to the bleeding port 3, thereby achieving the purpose of hemostasis. Compared with the compression hemostasis method, this lateral extrusion hemostasis method does not affect the flow of blood inside the blood vessel, and effectively avoids the occurrence of vascular complications. At the same time, the hemostatic device of the present invention has a simple structure and operation, low cost, and low professional requirements for operators, thereby reducing the postoperative hemostasis cost of patients.

[0044] It should be noted that the bleeding hole 3 is formed by puncturing the sheath, and the method of using the hemostatic device provided in the embodiment of the present invention is that after the vascular intervention surgery is completed and the sheath is pulled out, the adhesive member 1 is affixed around the bleeding hole 3, and then the retraction member 2 is used to switch the adhesive member 1 from a dispersed state to a retraction state to complete the closure of the bleeding hole 3; or, after the vascular intervention surgery is completed and before the sheath is pulled out, the adhesive member 1 is affixed around the bleeding hole 3, and then the retraction member 2 is assembled on the adhesive member 1, and then, while the sheath is pulled out, the retraction member 2 is used to switch the adhesive member 1 from a dispersed state to a retraction state. Switch to the retracted state to complete the closure of the bleeding port 3; or, before the vascular interventional surgery begins, first stick the adhesive 1 on the epidermis that needs surgery, then assemble the retracted member 2 on the adhesive 1, and then insert the sheath into the area enclosed by the adhesive 1 to perform the vascular interventional surgery. After the vascular interventional surgery is completed and while the sheath is pulled out, use the retracted member 2 to switch the adhesive 1 from the dispersed state to the retracted state; in this process, each adhesive 1 can drive the epidermis bonded thereto to retract toward the bleeding port 3, and then drive the blood vessels near the vascular bleeding port to retract, completing the closure of the vascular bleeding port. The method of using the hemostatic device provided in the embodiment of the present invention is selected according to the actual design of the retracted member 2 and the user's intention, and is not limited here.

[0045] It can be understood that the hemostatic device provided in the embodiment of the present invention can not only stop bleeding from the above-mentioned bleeding hole 3 and blood vessel bleeding hole formed by sheath puncture, but also stop bleeding from bleeding holes caused by sharp objects such as nails and awls, or stop bleeding from shorter strip-shaped bleeding holes.

[0046] It should also be noted that the patch 110 is a flexible thin-walled member. The patch 110 can be made of a film, cloth, etc. with medical glue on one side, or the patch 110 is a flat cloth adhesive tape, or the patch 110 is a flexible sheet with another side being an adhesive surface. The specific selection of the patch 110 is selected according to actual needs and is not limited here. The patch 110 is a flexible thin-walled member so that the patch 110 can fit the epidermis at different positions of the human body, so that the hemostatic device can stop bleeding at bleeding holes 3 in various parts of the human body.

[0047] In one embodiment, see Figures 1 to 3 The gathering member 2 is a rope 210, which can enclose a closed area. All protrusions 120 are in the closed area and each outer side surface 121 abuts against the rope 210. The rope 210 can be tightened to apply an external force directed to the bleeding outlet 3 to each protrusion 120 at the same time.

[0048] Specifically, after the vascular intervention surgery is completed and before the sheath is pulled out, the adhesive 1 is affixed around the bleeding port 3, and then the rope 210 is wrapped around the outer side 121 of all the protrusions 120. Then, while the sheath is pulled out, the rope 210 is tightened to switch the adhesive 1 from a dispersed state to a retracted state, thereby completing the closure of the bleeding port 3.

[0049] Among them, when the rope 210 is wrapped around the outer side surfaces 121 of all the protrusions 120, the rope 210 can be wrapped around a smaller number of turns first, so as to facilitate the rapid tightening of the rope 210 after the sheath is pulled out; after the rope 210 is tightened and the adhesive 1 is switched from a dispersed state to a retracted state, the rope 210 can continue to be wrapped around the outer side surfaces 121 of all the protrusions 120 or the rope 210 can be tied after continuing to be wrapped around, so as to fix the adhesive 1 in the retracted state, so that the bleeding port 3 is stably closed.

[0050] In a specific embodiment, see Figure 1 A first groove 123 is formed on the outer side surface 121 of all the protrusions 120 , and each first groove 123 is arranged along the circumference of the bleeding hole 3 , and the rope 210 passes through all the first grooves 123 in sequence to enclose and form a closed area.

[0051] By the above arrangement, the rope 210 is wound in the first groove 123, so that the rope 210 is always in the first groove 123 during the tensioning process. Compared with the rope 210 being directly wound around the outer side surface 121, the rope 210 will not slide off the protrusion 120 during the tensioning process, so as to ensure that the adhesive 1 can stably switch from the dispersed state to the retracted state, so that the bleeding port 3 is stably closed.

[0052] In another embodiment, see Figures 4 to 13The gathering member 2 includes a bearing portion 220 and an adjusting portion 230 having the same number as the convex portions 120; the bearing portion 220 is an annular structure, and all the convex portions 120 are placed in the inner area of ​​the bearing portion 220; each adjusting portion 230 is arranged in a one-to-one correspondence with each convex portion 120, one end of the adjusting portion 230 is connected to the bearing portion 220, and the other end of the adjusting portion 230 can abut against the corresponding convex portion 120, and the adjusting portion 230 can apply an external force directed to the bleeding port 3 to the convex portion 120, so as to switch the adhesive member 1 from a dispersed state to a gathered state.

[0053] By the above arrangement, the adjusting portion 230 abutting against the protrusion 120 can change its own posture, so that the adjusting portion 230 is squeezed between the protrusion 120 and the carrying ring, and the other end of the adjusting portion 230 is fixed on the carrying ring, so that the adjusting portion 230 converts the squeezing stress into an external force directed to the bleeding outlet 3 and applied to the protrusion 120.

[0054] In a specific embodiment, see Figures 4 to 8 The bearing portion 220 has a circular ring structure, and the outer side surface 121 has a fitting section 1241 away from the bearing portion 220 and a pressing section 1242 close to the bearing portion 220. The bearing portion 220 can rotate around the bleeding port 3. During the rotation of the bearing portion 220, each adjusting portion 230 slides from the fitting section 1241 to the pressing section 1242 at the same time, and each adjusting portion 230 is squeezed by the bearing portion 220 and the convex portion 120 at the same time, so as to apply an external force pointing to the bleeding port 3 to each convex portion 120 at the same time.

[0055] Through the above arrangement, before the start of the vascular interventional surgery, the adhesive 1 is first affixed to the epidermis where the surgery is required, and then the folding member 2 is put outside all the protrusions 120. At this time, the bearing portion 220 and the outer side surfaces 121 of all the protrusions 120 are arranged at a distance, and the adjusting portion 230 is between the bearing portion 220 and the protrusion 120 of the fitting section 1241. Then the sheath is inserted into the area enclosed by the adhesive 1 to perform the vascular interventional surgery. After the vascular interventional surgery is completed and the sheath is pulled out, the bearing portion 220 is rotated to drive the adjusting portion 230 to slide from the fitting section 1241 to the pressing section 1242. During this process, the adjusting portion 230 is subjected to extrusion stress and transmits external force directed to the bleeding port 3 to the outer side surface 121, so that the adhesive 1 switches from a dispersed state to a folded state, thereby completing the closure of the bleeding port 3.

[0056] In a more specific embodiment, see Figure 4 and Figure 6 A second groove 124 is formed on the outer side surface 121 , and the fitting section 1241 is the bottom of the second groove 124 . When the adjusting portion 230 switches from the dispersed state to the retracted state, one end of the adjusting portion 230 close to the convex portion 120 is placed in the second groove 124 .

[0057] Through the above arrangement, when the adjusting portion 230 slides from the fitting section 1241 to the pressing section 1242, the end of the adjusting portion 230 close to the protrusion 120 is always placed in the second groove 124, which guides the sliding of the adjusting portion 230 and prevents the adjusting portion 230 from sliding off the outer surface 121 during the sliding process, thereby ensuring that the adhesive 1 can stably switch from a dispersed state to a retracted state.

[0058] In another more specific embodiment, see Figure 6 There is a smooth transition between the fitting section 1241 and the pressing section 1242, and the end surface of the adjusting portion 230 close to the convex portion 120 is an arc surface.

[0059] Thus, when the adjusting portion 230 slides from the fitting section 1241 to the pressing section 1242 , the arc surface of the adjusting portion 230 abuts against the outer surface 121 , so that the adjusting portion 230 can slide easily from the fitting section 1241 to the pressing section 1242 .

[0060] For details, please refer to Figure 6 and Figure 8 A recess 1243 matching the arc surface is provided on the groove bottom of the pressing section 1242 , and at least part of the arc surface can fit the inner surface of the recess 1243 .

[0061] In this way, after the adjusting portion 230 slides to the pressing section 1242, one end of the adjusting portion 230 close to the protrusion 120 is clamped in the recess 1243 to stably fix the adjusting portion 230 on the pressing section 1242, so that the adhesive 1 can be stably in a retracted state, so that the bleeding hole 3 can be stably closed.

[0062] In another specific embodiment, see Figures 9 to 13 The adjusting part 230 is a screw 231, and a threaded through hole is radially opened on the bearing part 220. The screw 231 is screwed into the threaded through hole and abuts against the outer side surface 121. During the screwing-in process of the screw 231, the screw 231 can apply an external force directed to the bleeding outlet 3 to the convex part 120.

[0063] Through the above arrangement, before the start of the vascular interventional surgery, the adhesive 1 is first affixed to the epidermis where the surgery is required. After the screw 231 is screwed into the threaded through hole, it can abut against the outer side 121. Then the sheath is inserted into the area enclosed by the adhesive 1 to perform the vascular interventional surgery. After the vascular interventional surgery is completed and the sheath is pulled out, the screw 231 continues to be screwed in. During this process, the screw 231 is subjected to extrusion stress and transmits external force directed to the bleeding port 3 to the outer side 121, so that the adhesive 1 switches from a dispersed state to a contracted state, thereby completing the closure of the bleeding port 3.

[0064] In other embodiments, a third groove 125 is formed on the outer side surface 121, and during the process of the adhesive member 1 switching from the dispersed state to the retracted state, the end of the screw 231 close to the protrusion 120 is always placed in the third groove 125. During the process of the adhesive member 1 switching from the dispersed state to the retracted state and after the adhesive member 1 switches to the retracted state, the screw 231 will not be separated from the outer side surface 121, so that the adhesive member 1 can stably switch from the dispersed state to the retracted state.

[0065] In some embodiments, see Figures 1 to 13 All adhesives 1 are evenly arranged along the circumference of the bleeding hole 3 , and one end of each patch 110 close to the bleeding hole 3 is fan-shaped. In the retracted state, the patches 110 close to one end of the bleeding hole 3 are assembled to form a circle.

[0066] By the above arrangement, each adhesive member 1 can be evenly attached to the epidermis near the bleeding hole 3, and the above epidermis can be evenly gathered toward the bleeding hole 3 to achieve a better hemostasis effect. The end of each patch 110 near the bleeding hole 3 is arranged in a fan shape with the bleeding hole 3 as the center, so that each patch 110 can be assembled to form a closed circle after being gathered to close the bleeding hole 3, thereby preventing the external environment from contaminating the epidermis after the bleeding hole 3 is closed.

[0067] In some embodiments, the number of adhesive members 1 is six and they are evenly arranged along the circumference of the bleeding opening 3 , and the angle of the fan-shaped area of ​​each patch 110 is 60 degrees.

[0068] Of course, in other embodiments, the number of adhesive members 1 may be two, three, four, five, seven, etc., and the angle of the fan-shaped area of ​​the patch 110 multiplied by the number of adhesive members 1 (i.e., the number of patches 110) is 360 degrees. The specific number of adhesive members 1 is selected according to the bleeding hole 3 and the actual needs of the user, and is not limited here.

[0069] Of course, it is understandable that the patch 110 can also be arranged in a triangular shape (not shown), and the sum of the degrees of the sharp angles of each patch 110 pointing to the bleeding hole 3 is 360 degrees, wherein, in the folded state, all the patches 110 are pieced together to form a regular polygon (not shown).

[0070] In some embodiments, the protrusion 120 also has an inner side surface 122 close to the bleeding hole 3, and the inner side surface 122 is a smooth rounded surface, so that the protrusions 120 will not contact each other and interfere with each other when the adhesive 1 is in a retracted state, and at the same time, it also avoids sharp corners that may scratch the operator.

[0071] In other embodiments, the top surface of the convex portion 120 may also be an inclined surface that slopes downward from the top edge of the outer side surface 121 towards the bleeding port 3. At this time, the convex portion 120 is not provided with an inner side surface 122, and this structure can effectively save the manufacturing materials of the convex portion 120.

[0072] The foregoing are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
