A hemodialysis system includes the following: a dialysate handling unit for providing dialysate to the patient. This unit includes 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 includes 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 connected by a movable arm and are separate from and movable relative to each other while the hemodialysis is being performed. Significant economic and functional advantages can be achieved.
