ABSTRACT:
A continuous peritoneal dialysis is carried out by providing a dialyzer element having a filter membrane for being exposed within the peritoneal cavity and an interior dialysate passageway, the membrane having pores sufficient to allow diffusion of blood toxins, implanting the dialyzer element in the peritoneal cavity of a patient, infusing a transfer fluid into the patient's peritoneal cavity and continuously supplying substantially fresh dialysate fluid into interior dialysate passageway of the dialyzer element, directing the fluid along the passageway whereby it is exposed to the transfer fluid by diffusion through the membrane and whereby toxins from said transfer fluid are diffused into the dialysate in the dialyzer element to form toxic dialysate fluid, and continuously removing the toxic dialysate from said dialyzer element.
