Explanation

It is a materials used to make hollow fiber in blood dialyzer. Common materials include cellulose membrane, polyacrylonitrile membrane, polysulfone membrane, polymethyl methacrylate membrane, polycarbonate membrane, etc. Wood compatibility of membrane materials is an important index of dialyzer. The adsorption of egg endoplasmic reticulum, adhesion to platelets, and activation of complement and coagulation systems should be controlled at a lower level. The structure and properties of semi permeable membranes directly affect the quality of dialysis, such as the surface area, pore size, porosity, and retained molecular weight of the membrane, which have a decisive impact on the solute mass transfer rate and the size of toxic molecules removed during dialysis. For example, the membrane has a large surface area, fast mass transfer, and short dialysis time. The pore size intercepts large molecular weights and can remove small and medium molecule toxins.
