[0002] Nephrology is a clinical department set up in hospitals at all levels for the diagnosis and treatment of kidney diseases. Common renal replacement therapies include kidney transplantation, hemodialysis and peritoneal dialysis. Arteriovenous fistula formation is a surgical method to maintain vascular access for hemodialysis patients. It connects arteries and veins through surgery to achieve the blood flow requirements for hemodialysis, and can directly puncture blood vessels for hemodialysis treatment. After the needle is removed from the fistula, the patient needs to use a tourniquet to stop bleeding at the needle removal site. Tourniquets are the most common hemostatic products in medical institutions. They are made of medical polymer materials such as natural rubber or special rubber. They are long, flat and highly elastic.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] like Figure 1-Figure 4 As shown, the technical solution adopted by the utility model is as follows: a compression tourniquet after needle removal of fistula for use in nephrology, comprising a mounting block 3, wherein a first groove 14 and a second groove 15 are formed in the mounting block 3, wherein the first groove 14 is located above the second groove 15; and an adjustment component is provided in the first groove 14.

[0027] A reel 9 is rotatably disposed in the second groove 15, and the reel 9 is fixedly connected to the output end of the adjustment component. A handle 2 is rotatably disposed on the mounting block 3, and the handle 2 passes through the mounting block 3 and is fixedly connected to the input end of the adjustment component.

[0028] The adjustment assembly includes a worm 7, one end of which is fixedly connected to the handle 2, and the other end of which is rotatably connected to the mounting block 3. A worm wheel 8 is rotatably arranged in the first groove 14, and the top of the winding shaft 9 passes through the bottom of the first groove 14 and is fixedly connected to the bottom of the worm wheel 8, and the worm wheel 8 is meshed with the worm 7.

[0029] By rotating the handle 2 , the rotation of the handle 2 will drive the worm 7 to rotate. Since the worm wheel 8 is meshed with the worm 7 , the rotation of the worm 7 will drive the worm wheel 8 to rotate. The rotation of the worm wheel 8 will drive the winding shaft 9 to rotate.

[0030] Both ends of the winding shaft 9 are fixedly provided with fixed blocks, and a slide groove is provided in the fixed blocks, and a tourniquet 1 is slidably provided in the slide groove. A slider is provided at the end of the tourniquet 1, and the slider is slidably provided in the slide groove. A buckle assembly is fixedly provided at the end of the tourniquet 1 away from the winding shaft 9. The buckle assembly includes a clamping plate 5, and the clamping plate 5 is fixedly connected to the end of one of the tourniquets 1 away from the winding shaft 9, and a clamping block 6 is fixedly provided at the end of the other tourniquet 1 away from the winding shaft 9, and the clamping block 6 is clamped with the clamping plate 5. Through the clamping setting between the clamping plate 5 and the clamping block 6, the other ends of the two tourniquets 1 can be connected together, which is convenient for fixing the tourniquet 1.

[0031] The rotation of the reel 9 will reel in the tourniquet 1 at both ends of the reel 9. During the process of the reel 9 reeling in the tourniquet 1, the tourniquet 1 will be wound around the circumferential surface of the reel 9, thereby shortening the total length of the tourniquet 1 outside, thereby enhancing the tightening effect of the tourniquet 1. Due to the meshing between the worm wheel 8 and the worm 7, after the reel 9 is reeled in, the worm 7 will hinder the rotation of the worm wheel 8, thereby fixing the reel 9, preventing the tourniquet 1 from loosening, and better stopping bleeding from the patient's wound.

[0032] An opening groove 4 is formed at the bottom of the second groove 15 , and when the tourniquet 1 needs to be removed, the tourniquet 1 can be directly slid downward.

[0033] How it works

[0034] When the tourniquet 1 is needed to be used on the injured, the clamping plate 5 is first clamped together with the clamping block 6. Afterwards, the tightness of the tourniquet 1 is adjusted according to the actual use of the patient. When the tightness of the tourniquet 1 needs to be adjusted, the handle 2 is turned. The rotation of the handle 2 will drive the worm 7 to rotate, the rotation of the worm 7 will drive the worm wheel 8 to rotate, and the rotation of the worm wheel 8 will drive the reel 9 to rotate. The rotation of the reel 9 will reel the tourniquet 1 at both ends of the reel 9. During the process of reeling the tourniquet 1, the tourniquet 1 will be wound around the circumferential surface of the reel 9, thereby shortening the length of the tourniquet 1 outside the mounting block 3, and enabling the tourniquet 1 to better tighten the patient's wound. In addition, due to the cooperation between the worm wheel 8 and the worm 7, the reel 9 has a self-locking function after the adjustment is completed, preventing the tourniquet 1 from loosening and better stopping bleeding of the patient's wound.

[0035] When the tourniquet 1 needs to be cleaned, the handle 2 is rotated in the opposite direction to restore the tourniquet 1 to its initial state, and then the tourniquet 1 can be slid out through the opening slot 4, which facilitates the disassembly and cleaning of the tourniquet 1. In addition, the tourniquet 1 is made of rubber material, which is waterproof, easy to clean, and quick-drying.

[0036] Embodiment 2

[0037] like Figure 5-Figure 6 As shown, compared with the first embodiment, the adjustment component in the second embodiment includes a ratchet 13, the handle 2 is located at the top of the mounting block 3, the bottom of the handle 2 passes through the mounting block 3 and is fixedly connected to the top of the ratchet 13, and the bottom of the ratchet 13 is fixedly connected to the top of the winding shaft 9.

[0038] A connecting plate 12 is fixedly provided on one side of the mounting block 3, and a pull handle 10 is penetrated on the connecting plate 12. One end of the pull handle 10 passes through one side of the mounting block 3 and contacts and cooperates with the ratchet 13. A limit block 16 is fixedly provided on the pull handle 10, and the limit block 16 can slide between the connecting plate 12 and the mounting block 3. A spring 11 is sleeved on the pull handle 10, and one end of the spring 11 is fixedly connected to one side of the connecting plate 12, and the other end of the spring 11 is fixedly connected to the limit block 16.

[0039] When the handle 2 rotates, the ratchet 13 is driven to rotate, thereby driving the reel 9 to rotate, so that the reel 9 reels the tourniquet 1. While the reel 9 is reeling the tourniquet 1, the ratchet 13 drives the pull handle 10 to slide, thereby driving the limit block 16 to slide between the connecting plate 12 and the mounting block 3, so that the spring 11 is in a contracted or normal state. When the tourniquet 1 is adjusted to a suitable length, the handle 2 is stopped from rotating, and the pull handle 10 moves toward the ratchet 13 under the elastic action of the spring 11, so that the pull handle 10 is stuck on the ratchet 13, so that the reel 9 is fixed to prevent the tourniquet 1 from loosening.

[0040] How it works

[0041] Compared with the first embodiment, in the second embodiment, when the handle 2 is rotated, the rotation of the handle 2 will drive the ratchet 13 to rotate, and the rotation of the ratchet 13 will drive the reel 9 to rotate, and the rotation of the reel 9 will reel the tourniquet 1 at both ends of the reel 9. At the same time, when the reel 9 is reeling the tourniquet 1, the ratchet 13 will drive the pull handle 10 to slide, and the sliding of the pull handle 10 will drive the limit block 16 to slide between the connecting plate 12 and the mounting block 3, so that the spring 11 is in a contracted or normal state. When the tourniquet 1 is adjusted to a suitable length, the handle 2 is stopped from being rotated. At this time, the end of the pull handle 10 close to the ratchet 13 just breaks away from the contact with the inclined surface of the ratchet 13, and the pull handle 10 will move towards the ratchet 13 under the elastic action of the spring 11, so that the pull handle 10 is stuck on the ratchet 13, so that the reel 9 has a self-locking function after the adjustment is completed.
