Description

Technical Field

[0001] The utility model relates to the technical field of hemodialysis equipment, in particular to a hemodialysis catheter 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 through a dialyzer composed of countless hollow fibers. The blood and electrolyte solutions with similar concentrations to the body are exchanged inside and outside the hollow fibers through diffusion, ultrafiltration, adsorption and convection principles to remove metabolic waste from the body, maintain electrolyte and acid-base balance, and remove excess water from the body. The entire process of returning the purified blood is called hemodialysis. However, the current hemodialysis fixation method is mostly to use tape to adhere and fix the catheter connection to the skin, and the adhesion of the tape will decrease over time, causing the dialysis catheter to fall off or the needle to move, affecting normal hemodialysis. Therefore, we have introduced a hemodialysis catheter fixation device. Utility Model Content
