Abstract
The most commonly used artificial organ is the artificial kidney using dialysis membrane, a machine that performs a treatment known as hemodialysis. This process cleanses the bodies of renal failure patients by dialysis, filtration and adsorption which are simple physicochemical processes. Dialysis membranes account for the largest volume of artificial membranes, far outstripping other fields. Worldwide, the consumption of dialysis membranes has reached some 300 million square meters a year. More than 70% of the dialysis membranes in use are made of polysulfone. This paper describes dialyzers and dialysis membranes so far developed for blood purification.
