Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fixing strap. Background Art

[0002] During hemodialysis, patients often require two needles in the same arm, one for blood extraction and one for blood return. Due to the relatively thick dialysis needles, the steep bevel of the needle tip, and the angle of insertion, the needle holes on the skin and the blood vessel wall often do not overlap. Therefore, it is often necessary to wrap a hemostatic paper bandage around the needle hole and apply pressure along the direction of the blood vessel to stop bleeding. If the dialysis needle holes are located vertically, two bandages can be used to apply pressure and stop bleeding.

[0003] When two dialysis needle holes are side by side, they can only be fixed with a single bandage to compress and stop bleeding at both needle holes. Since the two bandages are not connected to the bandage, they are prone to positional displacement during compression and stop bleeding, which affects the compression and stop bleeding effect. Therefore, this application proposes a fixing bandage to solve the above problem. Utility Model Content

[0025] like Figure 1-5 As shown, the utility model provides a fixing strap, including a sliding adjustment piece 2, the sliding adjustment piece 2 fits the patient's arm, and two sliding sleeves 3 are movably connected to the sliding adjustment piece 2, each sliding sleeve 3 is movably connected to a hemostatic block 5, and both sides of the sliding adjustment piece 2 are movably connected with a strap 1 for fixing the device to the patient's arm, and the two straps 1 can be fixed by Velcro or other fixing methods such as buckles, and the hemostatic block 5 is used to compress the patient's dialysis needle hole for hemostasis, avoiding the problem that the hemostatic block 5 may be offset when the dialysis needle hole is directly fixed with the strap to compress the hemostatic block 5 for hemostasis, thereby affecting the hemostatic effect.

[0026] Furthermore, a sliding groove 4 is provided on the sliding sleeve 3, and the sliding groove 4 is sleeved on the sliding adjustment plate 2. The sliding sleeve 3 is sleeved on the sliding adjustment plate 2. The distance between the two hemostatic blocks 5 can be adjusted along the sliding adjustment plate 2 to adapt to the distance between the patient's dialysis needle holes. Other movable connection methods that can adjust the position along the sliding adjustment plate 2 can also be used.

[0027] Furthermore, the hemostatic block 5 is a hemostatic material, and the hemostatic block 5 can be made of hemostatic gauze, sterilized cotton, sterilized paper towels, etc., which can be used for compressing hemostatic materials.

[0028] Furthermore, a fixed tip 13 is fixedly connected to one side of the sleeve 3, and the fixed tip 13 is movably connected to the hemostatic block 5. An adjustable fixing mechanism is provided on the other side of the sleeve 3. The hemostatic block 5 is inserted into the fixed tip 13, and then the other side of the hemostatic block 5 is fixed by the adjustable fixing mechanism. The hemostatic block 5 is movably connected to the sleeve 3, which also facilitates the subsequent replacement of the hemostatic block 5.

[0029] Furthermore, the adjustable fixing mechanism includes a movable groove 6 provided on the sliding sleeve 3, and a push plate 7 is movably connected to the inner wall of the movable groove 6, and an adjusting tip 14 is fixedly connected to the push plate 7, and the adjusting tip 14 is movably connected to the hemostatic block 5.
