[0002] Hemodialysis is a process in which blood is drained from the body to the outside of the body and passed through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution (dialysate) containing electrolytes at concentrations similar to those in the body are exchanged inside and outside the hollow fibers to remove metabolic waste from the body and maintain electrolyte and acid-base balance. Clinically, the vascular access is fixed with a tube clamp.

[0003] A hemodialysis pipeline fixing device described in Publication No. CN219001665U relates to the technical field of fixing devices, comprising a supporting turntable, a telescopic rod is fixedly installed on the top of the supporting turntable, a lifting shaft is arranged on one side of the outer wall of the telescopic rod, a control rod is fixedly sleeved between the outer walls of the lifting shaft, a first hole is opened at the center of the top of the telescopic rod, a first bearing is fixedly inserted between the inner walls of the first hole, a first driving rod is movably inserted between the inner walls of the first bearing, a U-shaped frame is fixedly sleeved on the top of the first driving rod, a second hole is preset inside the U-shaped frame, and a hemodialysis pipeline fixing device is proposed to solve the problem that the height and angle of the catheter cannot be adjusted when the device of the above patent is used, which makes it difficult for medical staff to use it in the later stage, but the prior art still has defects:

[0004] 1. In the prior art, by rotating the threaded rod inserted at the top of each set of sliding seats, the two threaded rods inside each set of sliding seats push the fastening ring to move toward each other, and form an extrusion fixation for the dialysis tube.

When the dialysis tube is placed in the middle of the arc-shaped clamping plates 17 at both ends, the arc-shaped clamping plates 17 at both ends can stably clamp the dialysis tube with the help of the elastic force of the spring 18.2. The elastic force of the spring 18.2 is within the range of stably clamping the dialysis tube and will not squeeze the dialysis tube.

[0030] A storage slot 19 is provided in the middle of the upper end of the mounting seat 15 for medical staff to temporarily place some items for use.

[0031] When the utility model is implemented, Figure 1-6 As shown, when in use, the device can be conveniently moved to a suitable position near the hemodialysis equipment by means of the lockable universal wheel 2. After the position is determined, the lockable universal wheel 2 is adjusted to a locked state, and at the same time, the rotating hand wheel 5 is turned to drive the stud 4 to rotate inside the threaded tube 3.
