Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, and in particular relates to a zipper-type hemodialysis catheter sore surface healing fixer. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) containing similar concentrations to the body are exchanged through diffusion / convection inside and outside the hollow fibers to remove metabolic waste from the body and maintain electrolyte and acid-base balance. At the same time, it removes excess water from the body and returns the purified blood. The whole process is called hemodialysis. Establishing and maintaining a good vascular pathway for blood purification is the primary condition to ensure smooth blood purification and adequate dialysis.

[0003] The hemodialysis catheter is connected to the patient's body through the sore surface of the catheter. It is found in clinical practice that the hemodialysis catheter is easy to fall off and is not easy to fix. In addition, the sore surface of the patient's hemodialysis catheter is easily torn, causing pain to the patient. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0030] like Figure 1 As shown, in one embodiment of the utility model, a zipper-type hemodialysis catheter wound healing fixture includes a first adhesive seat 100 and a second adhesive seat 200. The middle section of the first adhesive seat 100 has a first catheter gasket ring 103, and the middle section of the second adhesive seat 200 has a second catheter gasket ring 203. The first catheter gasket ring 103 and the second catheter gasket ring 203 together form a catheter channel 500, and the hemodialysis catheter passes through the catheter channel 500.

[0031] When in use, the first adhesive seat 100 and the second adhesive seat 200 are both adhered to the patient's skin surface to fix the first adhesive seat 100 and the second adhesive seat 200. When the first adhesive seat 100 and the second adhesive seat 200 are fixed, the catheter channel 500 formed between the first catheter gasket ring 103 and the second catheter gasket ring 203 is put on the hemodialysis catheter to fix the hemodialysis catheter.

[0032] Correspondingly, in an embodiment of the utility model, the first bonding seat 100 and the second bonding seat 200 are connected and fixed by a zipper structure, wherein the zipper structure includes a first zipper 300 and a second zipper 400, wherein one end of the first bonding seat 100 has a first sprocket group 101, and the other end of the first bonding seat 100 has a second sprocket group 102; one end of the second bonding seat 200 has a third sprocket group 201, and the other end of the second bonding seat 200 has a fourth sprocket group 202, the first sprocket group 101 cooperates with the third sprocket group 201, and the first sprocket group 101 and the third sprocket group 201 are connected by the first zipper 300; the second sprocket group 102 and the fourth sprocket group 202 are connected by the second zipper 400.

[0033] By setting the zipper structure, the first adhesive seat 100 and the second adhesive seat 200 adhered to the skin can be brought closer to each other, so that on the one hand, the wounds on the skin are closed to avoid pulling of the wound surface and relieve the pain of the patient. In addition, a catheter channel 500 is formed between the first catheter gasket 103 and the second catheter gasket 203 close to each other, which is used to clamp the hemodialysis catheter to stabilize the hemodialysis catheter and prevent it from falling off.

[0034] Further, in the embodiment of the present utility model, the first conduit gasket 103 and the second conduit gasket 203 have the same structure. Figure 2 and Figure 3 , the structure of the first catheter gasket 103 is described in detail.

[0035] like Figure 2 and Figure 3 As shown, in an embodiment of the utility model, the first catheter gasket 103 is provided with a mounting groove 1031, and a limiting block 1032 is arranged on the inner wall of the mounting groove 1031, the edge of the first bonding seat 100 is pressed against the mounting groove 1031, and a positioning block 104 cooperating with the limiting block 1032 is arranged on the first bonding seat 100, the inclined surface of the limiting block 1032 faces the open direction of the mounting groove 1031, and the inclined surface of the positioning block 104 is opposite to the limiting block 1032, so that the first catheter gasket 103 is sleeved on the first bonding seat 100, that is, when the first bonding seat 100 is pressed against the mounting groove 1031, the first catheter gasket 103 is fixed on the first bonding seat 100 through the mutual cooperation of the limiting block 1032 and the positioning block 104.

[0036] The first catheter gasket 103 and the second catheter gasket 203 provided in the embodiment of the utility model can achieve the effect of fixing the first catheter gasket 103 on the first bonding seat 100 and the effect of fixing the second catheter gasket 203 on the second bonding seat 200 through the mutual cooperation of the corresponding limit blocks 1032 and the positioning blocks 104, and the operation is convenient.

[0037] The first catheter gasket 103 and the second catheter gasket 203 provided in the embodiment of the utility model are made of rubber material. When they cooperate with the hemodialysis catheter, they prevent slippage of the contact surface between the hemodialysis catheter and the first catheter gasket 103 and the second catheter gasket 203, that is, provide friction force on the contact surface to maintain a stable state of clamping the hemodialysis catheter.

[0038] Furthermore, in the embodiment of the utility model, both the first adhesive seat 100 and the second adhesive seat 200 are provided with an adhesive layer 105 for bonding and fixing the first adhesive seat 100 and the second adhesive seat 200 to the surface of the patient's skin.
