Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

Fixed clamping blocks 2 are fixedly provided at both ends of the fixed rod 1, a box body 3 is fixedly provided on one side of the fixed clamping block 2, guide grooves 4 are provided on both sides of the box body 3, and a through hole 16 is provided on the side of the box body 3 away from the fixed rod 1; there are two movable rods 5, one end of each movable rod 5 is fixedly provided with a movable clamping block 6, and the end of the movable rod 5 away from the movable clamping block 6 passes through the guide groove 4 and extends to the inside of the box body 3; the rotating assembly is installed inside the box body 3 for rotating the movable rod 5.

[0024] See also Figure 1-Figure 5 The rotating assembly shown in the figure includes a mounting groove 7 opened at one end of the movable rod 5, a shaft rod 8 is arranged inside the mounting groove 7, two ends of the shaft rod 8 extend to both sides of the movable rod 5 and are rotatably connected to the inner wall of the box body 3, a gear 9 is fixedly arranged on the shaft rod 8, a push plate 10 is arranged between the two gears 9, teeth 11 meshing with the gear 9 are fixedly arranged on both sides of the push plate 10, a slide groove 12 is opened in the middle of the push plate 10, a first spring 13 is fixedly arranged at one end of the inner side of the slide groove 12, and one end of the push plate 10 passes through the through hole 16 and extends to the outside of the box body 3 and is fixedly connected to one side of the handle 17;

[0025] See also Figure 1-Figure 5 The rotating assembly shown in the figure also includes a mounting hole 14 opened in the middle of the fixed rod 1, and the push plate 10 is slidably arranged inside the mounting hole 14, wherein one end of the push plate 10 extends to one side of the fixed rod 1 and is fixedly connected to the limit plate 18, and a positioning column 15 is slidably provided inside the slide groove 12, and both ends of the positioning column 15 are fixedly connected to the inner wall of the mounting hole 14, and one end of the first spring 13 is fixedly connected to one side of the positioning column 15.

[0026] When using the blood perfusion device fixing clamp: first, the user holds the box body 3 and the fixing rod 1 together, and then uses the thumb to push the handle 17 on one side of the box body 3. When the handle 17 is pushed by the thumb, the push plate 10 on the side of the handle 17 moves toward the inside of the box body 3. The movement of the push plate 10 will squeeze the first spring 13 in the slide groove 12, so that the first spring 13 reserves elastic potential energy. At the same time, when the push plate 10 moves, it drives the teeth 11 on both sides to engage with the gear 9 on the shaft rod 8 fixedly connected to the end of the movable rod 5, so as to drive the shaft rod 8 and the gear 9 to rotate. When the shaft rod 8 rotates, it can drive the movable rod 5 to rotate. The rotation of the movable rod 5 can drive the movable clamping block 6 at one end thereof to expand and separate from the fixed clamping block 2. At this time, one of the fixed clamping blocks 2 is placed on one side of the bracket on the side wall of the dialysis device, and then the blood perfusion device is placed on the concave surface of the other fixed clamping block 2. At this time, the user's thumb releases the pressure on the handle 17, and the push plate 10 loses the pressure. The push of pressure, at this time, the first spring 13 in the slide groove 12 releases elastic potential energy, pushes the push plate 10 to move in the opposite direction, and the reverse movement of the push plate 10 will drive the teeth 11 to mesh and drive the gear 9 to rotate in the opposite direction. The reverse rotation of the gear 9 drives the shaft 8 to rotate in the opposite direction, which can drive the movable rod 5 to rotate in the opposite direction, so that the movable clamping block 6 at one end of the movable rod 5 is close to the side of the fixed clamping block 2, so that the fixed clamping block 2 and the movable clamping block 6 can clamp the blood perfusion device, and the fixed rod 1 is clamped and fixed on one side of the side wall of the dialysis device, so that the blood perfusion device is clamped on one side of the dialysis device, and the convenience of clamping and fixing the blood perfusion device is increased. When the first spring 13 is installed, the initial state of the first spring 13 when it is installed in the slide groove 12 is in a compressed state, so that its initial state has elastic potential energy, which can realize that when the user releases the pressure on the handle 17, the push plate 10 is quickly pushed back, and at the same time, the clamping force of the fixed clamping block 2 and the movable clamping block 6 is increased, and the stability of clamping the blood perfusion device is increased.

[0027] During use, when the height of the blood perfusion device needs to be adjusted according to the patient's use, the user holds the box body 3 and the fixed rod 1 to press the handle 17, and holds the blood perfusion device with one hand, so that the rotating assembly drives the fixed clamp block 2 and the movable clamp block 6 to separate, so that the fixed clamp blocks 2 and the movable clamp block 6 at both ends of the fixed rod 1 are separated from the blood perfusion device and the dialysis equipment support, and then slides the fixed rod 1 upward to make the fixed clamp block 2 at the height position that needs to be adjusted, and then rotates the fixed rod 1 to rotate the fixed clamp block 2 at one end of the fixed rod to the required clamping direction. After the position and direction adjustment is completed, the pressing of the handle 17 is released again. Under the push of the first spring 13, the push plate 10 clamps and fixes the fixed clamp block 2 and the movable clamp block 6 again with the blood perfusion device and the dialysis equipment support frame to achieve fixed clamping of the blood perfusion device, and the adjustment of the clamping height position and direction of the blood perfusion device can be completed, which increases the convenience of use and avoids the traditional pinching method of fixing the blood perfusion device and affecting the adjustment of the height of the blood perfusion device.

[0028] The device has a simple structure and is convenient for users to use. The blood perfusion device can be clamped and fixed by adding a fixed rod 1, a fixed clamp block 2, a movable clamp block 6, a movable rod 5 and a rotating assembly. At the same time, the height and direction of the fixed clamp block and the movable clamp block clamped on one side of the dialysis device can be easily adjusted, so that the clamping height and direction of the blood perfusion device can be adjusted, which effectively increases the convenience of use for users and solves the problem that the height and direction of the blood perfusion device cannot be adjusted after being fixed by the traditional pinching and clamping method.
