Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of compression hemostasis devices, specifically relating to a dual-point positioning compression hemostasis device. Background Technology
[0002] Arteriovenous fistulas are the core vascular access for maintenance hemodialysis in patients with end-stage renal disease. After hemodialysis, precise compression of the fistula puncture site is required to stop bleeding. The core requirements are to achieve double-point alignment, controllable pressure, and continuous stability. It is necessary to avoid bleeding at the puncture site and prevent excessive compression from causing blood flow blockage and thrombosis in the fistula. At the same time, it is necessary to adapt to the narrow operating space of the wrist / forearm and the differences in arm size among different patients.
[0003] Currently, most arteriovenous fistula compression hemostasis devices used in clinical and home settings are single-pressure surfaces or simple bandage structures, lacking a dual-point positioning structure. The compression point is only aligned with the skin puncture point and does not cover the vascular puncture point, which can easily lead to subcutaneous hematoma and damage to the fistula endothelium, affecting the lifespan of the arteriovenous fistula.

[0022] like Figure 1-4 The illustrated dual-point positioning compression hemostasis device includes a fixing part 1, a first hemostasis part 2, and a second hemostasis part 3. The first hemostasis part 2 includes a first positioning frame 21 and a first pressing element 22; the first pressing element 22 is detachably connected to the first positioning frame 21. The second hemostasis part 3 includes a second positioning frame 31 and a second pressing element 32; the second pressing element 32 is detachably connected to the second positioning frame 31. One end of the fixing part 1 is slidably connected to the first positioning frame 21, and the other end is slidably connected to the second positioning frame 31. It also includes an adjustment part 4; one end of the adjustment part 4 is detachably connected to the end of the first positioning frame 21 away from the fixing part 1, and the other end is detachably connected to the end of the second positioning frame 31 away from the fixing part 1. The first hemostasis part 2 and the second hemostasis part 3 provide precise compression hemostasis at skin puncture points and vascular puncture points, effectively preventing subcutaneous hematoma and fistula endothelial damage, and extending the lifespan of the arteriovenous fistula. The states of the first hemostatic part 2 and the second hemostatic part 3 can be adjusted separately to regulate the pressure, meeting the dual requirements of dual-point positioning and precise pressure control.
[0023] When in use, the fixing part 1 is used to attach the first hemostatic part 2 and the second hemostatic part 3 to the patient's body surface. Then, the adjusting part 4 is used to adjust the lateral and longitudinal distances between the first hemostatic part 2 and the second hemostatic part 3 so that the first hemostatic part 2 and the second hemostatic part 3 are respectively aligned with the skin puncture point and the blood vessel puncture point, so as to apply precise pressure to the skin puncture point and the blood vessel puncture point.
[0024] like Figure 1-3 As shown, the first pressing component 22 includes a first pressure adjusting structure 221, a first connecting rod 222, a first support frame 223, and a first pressing structure 225. The outer wall of the first pressure adjusting structure 221 is detachably connected to the first support frame 223. One end of the first connecting rod 222 is fixedly connected to the first support frame 223, and the other end passes through the first adjusting structure. The first pressing structure 225 is wrapped around the outer wall of the first connecting rod 222. One end of the first pressing component 22 abuts against the first support frame 223, and the other end abuts against the first pressure adjusting structure 221. In use, the first positioning frame 21 is aligned with the skin puncture point or blood vessel puncture point, and then the fixing part 1 is used to wear the first positioning frame 21 on the patient's body surface. Then, the first pressure adjusting structure 221 is rotated, and the first pressure adjusting structure 221 moves towards the patient's body surface, thereby compressing the first pressing structure 225, so that the first support frame 223 compresses the skin puncture point or blood vessel puncture point to stop bleeding.
[0025] Specifically, the first pressing structure 225 is a linear compression spring. According to the spring force formula, the pressure on the spring is proportional to the change in its length. Therefore, by measuring the deformation of the first pressing structure 225, the pressure exerted by the patient's skin on the first pressing structure 225 can be obtained. This pressure is the pressure exerted by the first support frame 223 on the skin puncture point or blood vessel puncture point. Based on this principle, a scale is set at the end of the first connecting rod 222 away from the first support frame 223. Based on the length of the first connecting rod 222 passing through the first adjustment structure, the pressure of the first support frame 223 on the skin puncture point or blood vessel puncture point under the current condition can be obtained.
[0026] Preferably, a first hemostatic bracket 213 is fixedly connected to the first positioning frame 21; the first hemostatic bracket 213 is threadedly connected to the first pressure regulating structure 221. Rotating the first pressure regulating structure 221 changes its position, thereby adjusting the pressure of the first pressing element 22 on the skin puncture point or blood vessel puncture point.
[0027] Furthermore, the first pressing component 22 also includes a first buffer structure 224; the first buffer structure 224 is detachably connected to the side of the first support frame 223 away from the first connecting rod 222. The first buffer structure 224 can be replaced by hand, and the main components can be sterilized at high temperatures, taking into account both disposable hygiene requirements and the economy of reuse, making it suitable for mass use in dialysis rooms and for patients' home use.
[0028] Specifically, the first buffer structure 224 includes an absorbent sponge.
[0029] In some embodiments of this application, the first hemostatic part 2 further includes a first limiting member 23; the first limiting member 23 is threadedly connected to the first pressure adjusting structure 221. The first limiting member 23 is located in the direction away from the patient from the first hemostatic frame. In use, the first pressure adjusting structure 221 is rotated to adjust the pressure of the first pressing member 22 on the patient. Then, the first limiting member 23 is tightened, causing the first limiting member 23 to press against the side wall of the first hemostatic frame, generating additional friction and preventing the first pressure adjusting structure 221 from loosening.
[0030] The structure of the second pressing member 32 is the same as that of the first pressing member 22. For example... Figure 1-3As shown, the second pressing component 32 includes a second pressure adjusting structure, a second connecting rod, a second support frame, and a second pressing structure. The outer wall of the second pressure adjusting structure is detachably connected to the second support frame. One end of the second connecting rod is fixedly connected to the second support frame, and the other end passes through the second adjusting structure. The second pressing structure is wrapped around the outer wall of the second connecting rod. One end of the second pressing component 32 abuts against the second support frame, and the other end abuts against the second pressure adjusting structure. In use, the second positioning frame 31 is aligned with the skin puncture point or blood vessel puncture point, and then the fixing part 1 is used to wear the second positioning frame 31 on the patient's body surface. Then, the second pressure adjusting structure is rotated, and the second pressure adjusting structure moves towards the patient's body surface, thereby compressing the second pressing structure, so that the second support frame compresses the skin puncture point or blood vessel puncture point to stop bleeding.
[0031] Specifically, the second pressing structure is a linear compression spring. According to the spring force formula, the pressure on a spring is directly proportional to its length change. Therefore, by measuring the deformation of the second pressing structure, the pressure exerted by the patient's skin on it can be determined. This pressure is the pressure exerted by the second support frame on the skin puncture point or blood vessel puncture point. Based on this principle, a scale is set at the end of the second connecting rod away from the second support frame. By measuring the length of the second connecting rod passing through the second adjustment structure, the pressure of the second support frame on the skin puncture point or blood vessel puncture point under the current condition can be determined.
[0032] Preferably, a second hemostatic bracket is fixedly connected to the second positioning frame 31; the second hemostatic bracket is threadedly connected to the second pressure regulating structure. Rotating the second pressure regulating structure changes its position, thereby adjusting the pressure of the second pressing element 32 on the skin puncture point or blood vessel puncture point.
[0033] Furthermore, the second pressing component 32 also includes a second buffer structure; the second buffer structure is detachably connected to the side of the second support frame away from the second connecting rod. The second buffer structure can be replaced by hand, and the main components can be sterilized at high temperatures, taking into account both disposable hygiene requirements and the economy of reusability, making it suitable for mass use in dialysis rooms and for patients' home use.
[0034] Specifically, the second buffer structure includes an absorbent sponge.
[0035] In some embodiments of this application, the second hemostatic part 3 further includes a second limiting member; the second limiting member is threadedly connected to the second pressure adjusting structure. The second limiting member is located in the direction away from the patient from the second hemostatic frame. In use, the second pressure adjusting structure is rotated to adjust the pressure of the second pressing member 32 on the patient. Then, the second limiting member is tightened so that the second limiting member presses against the side wall of the second hemostatic frame, generating additional frictional force to prevent the second pressure adjusting structure from loosening.
[0036] like Figure 1-4As shown, the fixing part 1 includes a first fixing strap 11 and a second fixing strap 12; one end of the first fixing strap 11 is detachably connected to the second fixing strap 12, and the other end is connected to the first positioning frame 21; the end of the second fixing strap 12 away from the first fixing strap 11 is connected to the second positioning frame 31. The fixing part 1, the first hemostatic part 2, the second hemostatic part 3, and the adjusting part 4 form a ring-shaped structure. By adjusting the total length of the first fixing strap 11 and the second fixing strap 12, the size of this ring-shaped structure can be adjusted, thereby allowing this ring-shaped structure to be worn on the patient's body surface.
[0037] The first positioning frame 21 has a first fixed bracket 211 at one end and a first adjusting bracket 212 at the other end; the first fixed bracket 211 is connected to the fixing part 1; the first adjusting bracket 212 is connected to the adjusting part 4. The second positioning frame 31 has a second fixed bracket 312 at one end and a second adjusting bracket 311 at the other end; the second fixed bracket 312 is connected to the fixing part 1; the second adjusting bracket 311 is connected to the adjusting part 4.
[0038] The adjusting part 4 is a strap that can be detachably connected at both ends. The adjusting part 4 passes around the first adjusting bracket 212 and the second adjusting bracket 311 to form a ring. By adjusting the length of this ring, the lateral distance between the first hemostatic part 2 and the second hemostatic part 3 can be adjusted. By changing the position of this ring structure on the first adjusting bracket 212 and the second adjusting bracket 311, the longitudinal distance between the first hemostatic part 2 and the second hemostatic part 3 can be adjusted.
[0039] The above are merely specific embodiments of this application. Under the guidance of the above teachings, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of this application, and the scope of protection of this application should be determined by the scope of the claims.
