ABSTRACT:
A flexible artificial kidney, capable of being worn directly on the body of the patient, and characterized by a flexible hollow retentate chamber of about 3 to 50 cm.sup.3 in volume surrounded by a jacketed flexible dialysate chamber of about 300 to 5,000 cm.sup.3 in volume, preferably such that the dialysate chamber is at least about 100 times larger than the retentate chamber. Blood inlet and outlet lines to and from the retentate chamber are passed in fluid tight relationship through the jacketed wall of the dialysate chamber which in turn has a closable opening for filling and discharging the dialysate liquid. This artificial kidney is especially effective when adsorbent materials are added to the liquid in the dialysate chamber.
