[0002] In hemodialysis treatment, the fixation of temporary catheters (such as the right internal jugular vein catheter) is a key issue. Traditional fixation methods usually use adhesive tape, but adhesive tape fixation has many disadvantages.

[0003] First, the tape easily falls off, making the catheter securely in place and potentially causing it to slip out of the body due to the catheter wire falling off. Second, for patients with long hair, the tape easily sticks to their hair during removal, increasing pain. Furthermore, existing catheters lack a tight seal at the end, making it easy for dust to enter and cause internal contamination. Utility Model Content

[0004] The present invention aims to provide a hemodialysis tubing fixation device to address the aforementioned issues with adhesive tape, which can easily fall off, leading to unstable catheter fixation and the risk of the catheter slipping out of the body due to the catheter line falling off. Furthermore, for patients with long hair, the adhesive tape can easily get stuck to the hair during removal, increasing pain. Furthermore, existing catheters suffer from insufficient sealing at the end of the catheter during fixation, making it susceptible to internal contamination caused by dust.

[0011] Preferably, a gasket made of silicone material is installed at the end of the positioning rod.

[0012] Preferably, the top end of the hanging rope is rotatably connected to the pendant via a rotating shaft.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This hemodialysis tube fixing device effectively solves the problems of easy falling off, easy adhesion to hair, and insufficient sealing of the catheter end that exist in traditional adhesive tape fixing methods. By adopting a unique pendant structure and hanging rope connection method, the hemodialysis tube is stably fixed and the risk of the catheter slipping out of the body is reduced. At the same time, the design of the protective cover and the positioning ring ensures that the end of the dialysis catheter has good sealing, effectively preventing the entry of dust and dirt, and avoiding the occurrence of internal contamination. The positioning ring firmly fixes the dialysis catheter in the protective cover through the positioning rod, preventing the catheter from shaking and falling off.
