Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary fixing structures for hemodialysis tubing, and particularly to a hemodialysis tubing fixing device. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It involves draining the blood in the body to the outside, passing it through a dialyzer composed of countless hollow fibers. Inside and outside each hollow fiber, the blood and an electrolyte solution (dialysate) with a concentration similar to that of the body carry out mass exchange through the principles of diffusion, ultrafiltration, adsorption, and convection to remove metabolic wastes in the body, maintain electrolyte and acid-base balance, and at the same time remove excess water in the body. The whole process of returning the purified blood is called hemodialysis.

[0003] Based on the above, currently, since hemodialysis takes a relatively long time, during this process, in order to prevent the tubing from being pulled off or the needle from shifting due to the patient's movements, it is generally necessary to fix the tubing. However, most fixing devices will limit the patient's hand while fixing the tubing, causing the patient's hand to be in a rigid state for a long time during dialysis, and the delivery tube is mostly in a low-temperature state when being returned.
