At present, hemodialysis is a common treatment for relatively serious kidney diseases, and is very important for maintaining the life of kidney patients. The dialysis apparatus generally includes a dialyzer, a dialysis tube, and a dialysate supply device, and uses the dialysis tube to discharge metabolic wastes of the human body. The treatment mode is necessary for life support of patients with severe kidney diseases, but the dialysis tube needs to puncture the human body and keep smooth flow of the dialysis fluid in the dialysis process, so that the dialysis tube needs to be relatively fixed with the human body, such as a bracket structure arranged on a dialysis treatment bed, so that the movement of the dialysis tube relative to the human body can be reduced, and pain and injury to the patients caused by pulling the dialysis tube can be reduced. However, this is only suitable for dialysis treatment of patients on a fixed bed, and there is still the possibility of damage caused by pulling the dialysis tubing when the patient moves. Moreover, the general rigid support structure has limited applicability, and the variation of the length and thickness of the dialysis tube can influence the reliability of fixing on the support, and the unreliable fixing of the pipeline can be caused by insufficient length or overlong length.
