Technical Field

[0001] The present application relates to the technical field of hemodialysis tubes, and in particular to a hemodialysis tube fixing device. 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 and passes it through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution containing similar concentrations to the body are exchanged inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection, thereby removing metabolic waste from the body, maintaining electrolyte and acid-base balance, and removing excess water from the body. The entire process of returning the purified blood is called hemodialysis.

[0003] During hemodialysis, the solution is introduced into the human body through the hemodialysis tube. However, the hemodialysis tube is long and soft, and is prone to tangling during use, making it inconvenient to use.

[0004] Therefore, the present application provides a hemodialysis tubing fixing device to solve the above problems. Utility Model Content

The pipe fixing block is subjected to the pressure of the hemodialysis tube, so that the pipe fixing block drives the sliding block to slide outside the guide rod arranged inside the fixed operating block, and the hemodialysis tube is placed inside the two sets of pipe fixing blocks. The two sets of pipe fixing blocks fix the hemodialysis tube, thereby avoiding the phenomenon of tangling between the hemodialysis tubes. The operation is simple, fast and convenient to use;

[0008] Preferably, in order to solve the problem of convenient installation and disassembly, the installation mechanism includes an installation operation block, the internal rotation of the installation operation block is connected to a bidirectional screw, the external ends of the bidirectional screw are threadedly connected to a moving block, one side of the moving block is fixedly connected to a mounting clamp block, the installation clamp block is adapted to the infusion stand, the bidirectional screw is threadedly connected to the moving block, so that the moving block is forced to move in opposite directions, the installation clamp block is adapted to the infusion stand, and the fixing mechanism is fixed to the outside of the infusion stand by the installation clamp block, which can facilitate the installation of the fixing mechanism, is simple and quick to operate, and is easy to use.

[0009] Preferably, in order to solve the problem of convenient operation of the sliding block, a return spring is provided on the outer sleeve of the guide rod, and the return spring is fixedly connected between the fixed operating block and the sliding block. During the sliding process, the sliding block compresses the return spring set on the side, and the rebound force of the return spring facilitates the sliding block to return to its original state, which is convenient to use.

[0012] The fixing mechanism places the hemodialysis tube between two sets of tube fixing blocks. The tube fixing blocks are subjected to pressure from the hemodialysis tube, so that the tube fixing blocks drive the sliding blocks to slide outside the guide rods provided inside the fixed operation blocks.

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] Example 1

[0021] This embodiment provides a hemodialysis tubing fixing device, such as Figure 1-3As shown, the hemodialysis tubing fixing device comprises a fixing mechanism 1 for fixing the hemodialysis tubing and a mounting mechanism 2 for mounting and fixing;

[0022] During use, the hemodialysis tube can be conveniently fixed by the provided fixing mechanism 1, thereby avoiding the phenomenon of entanglement between the hemodialysis tubes. The operation is simple and fast, and the use is convenient. The installation mechanism 2 can be conveniently installed on the fixing mechanism 1. The operation is simple and fast, and the use is convenient.

[0023] Specifically, the fixing mechanism 1 includes a fixed operating block 11, a guide rod 12 is symmetrically arranged inside the fixed operating block 11, and a sliding block 13 is symmetrically arranged outside the guide rod 12. The sliding block 13 is slidably connected to the guide rod 12, and one end of the sliding block 13 is fixedly connected to a pipe fixing block 14. The side of the pipe fixing block 14 close to the other end is arranged in an arc shape, and the pipe fixing block 14 is adapted to the hemodialysis tube;

[0024] During use, the hemodialysis tube is placed between the two sets of tube fixing blocks 14. The tube fixing blocks 14 are subjected to the pressure of the hemodialysis tube, so that the tube fixing blocks 14 drive the sliding blocks 13 to slide outside the guide rod 12 provided inside the fixed operation block 11. The hemodialysis tube is placed inside the two sets of tube fixing blocks 14. The two sets of tube fixing blocks 14 fix the hemodialysis tube, thereby avoiding the phenomenon of entanglement between the hemodialysis tubes. The operation is simple, fast and easy to use.

[0025] Specifically, a return spring 15 is provided on the outside of the guide rod 12, and the return spring 15 is fixedly connected between the fixed operating block 11 and the sliding block 13. When the sliding block 13 slides, the sliding block 13 compresses the return spring 15 set on the side. The rebound force of the return spring 15 facilitates the sliding block 13 to return to its original state, which is convenient to use.

[0026] Example 2

[0027] The difference from Example 1 is that after the hemodialysis tube is fixed, it needs to be fixed to avoid the problem of manual holding and fixing. To this end, the installation mechanism 2 includes an installation operation block 21. The internal rotation of the installation operation block 21 is connected to a bidirectional screw 22. The external ends of the bidirectional screw 22 are threadedly connected to a moving block 24. One side of the moving block 24 is fixedly connected to a mounting clamp 26. The mounting clamp 26 is adapted to the infusion stand. The bidirectional screw 22 is threadedly connected to the moving block 24, so that the moving block 24 is forced to move in opposite directions. The mounting clamp 26 is adapted to the infusion stand. The fixing mechanism 1 is fixed to the outside of the infusion stand by the mounting clamp 26, which can facilitate the installation of the fixing mechanism 1. The operation is simple, fast, and easy to use.

[0028] Specifically, a turning handle 23 is rotatably connected to the outer side of the installation operation block 21, and one end of the turning handle 23 extends to the interior of the installation operation block 21 and is fixedly connected to the bidirectional screw 22. By rotating the turning handle 23, the turning handle 23 can drive the bidirectional screw 22 to rotate inside the installation operation block 21, thereby facilitating operation and easy use.

[0029] Furthermore, two sets of limiting guide rods 25 are symmetrically fixedly connected inside the installation operation block 21, and the moving block 24 is arranged outside the limiting guide rod 25, and the moving block 24 is slidingly connected to the limiting guide rod 25. The moving block 24 slides outside the limiting guide rod 25 under force, and the stability of the movement of the moving block 24 is improved by the setting of the limiting guide rod 25.
