[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 an electrolyte solution (dialysate) containing electrolytes at similar concentrations to the body are exchanged through diffusion / convection inside and outside the hollow fibers 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. Pure water pipelines and related pipelines for hemodialysis need to be strictly cleaned, disinfected and sterilized after each use, otherwise it may cause infection and other dangerous situations.
