A hemodialysis system comprises the following: a dialysate handling unit for providing dialysate to the patient. This unit comprises a hemodialysis solution pump and apparatus for monitoring hemodialysis solution safety such as a conductivity tester. Additionally a solution heater and appropriate conventional controls can be provided, as well as a proportioning system, an ultrafiltration measuring unit, and other known apparatus for handling dialysis solution. A blood handling unit is also provided, which comprises a membrane dialyzer and holder, a blood pump, blood flow tubing and safety equipment for monitoring blood flow as it is pumped through the arterial/venous blood conduit set tubing from the patient, through the membrane dialyzer, and back to the patient. A first conduit is present for conveying fresh dialysate from the dialysate handling unit to the blood handling unit (or directly to the membrane dialyzer). A second conduit is provided for conveying spent hemodialysis solution away from the blood handling unit. By this invention, the dialysate handling unit and the blood handling unit are separate from and movable relative to each other while the hemodialysis is being performed. Significant economic and functional advantages can be achieved.
