Abstract

An artificial kidney dialysate system provides a predetermined rate of flow of dialysate solution into a dialyzer, and a predetermined rate of flow of dialysate solution from the outlet of the dialyzer. Through positive displacement pumping at the inlet and outlet of the dialyzer, the two rates can be adjusted so that an accurately predetermined quantity of excess fluid from the patient's blood stream can be withdrawn into the dialysate solution.
