Safety and biological aspects of present techniques of haemodialysis
Haemodialysis (HD) is a treatment in which blood from the patient is lead through a tubing system into a dialysis device in a extracorporeal circuit. This circuit contains semipermeable membranes (dialyzer). Blood with uraemic toxins flows on one side, and a salt solution flows on the other side. The salt solution flushes away waste products that have passed the membrane by diffusion or convection through small pores.
