[Automatic semicontinuous peritoneal dialysis with volumetric cycle control]

An automatic peritoneal dialyser constructed by the authors is presented. It works on the principle of so-called semi-continuous peritoneal dialysis. Only 200 ml of dialysate are exchanged per cycle after the peritoneum has been filled. Whereas with the time control used by Di Paolo the outflow can fluctuate considerably due to various disturbing factors, volume control makes it possible to balance inflow and outflow precisely. The advantages of this procedure of peritoneal dialysis are that it functions automatically and that it therefore requires little attention from staff.
