ABSTRACT:
An improved valving system is provided in a dialysis system in which the dialysis solution flow path through the dialyzer may be sealed off adjacent the inlet and outlet of the dialyzer, with the pumped dialysis solution being shunted so that the pump and heater do not need to be turned off. As ultrafiltration takes place over a predetermined period of time, it can be directly measured by monitoring the liquid level of a reservoir connected to the sealed portion of the dialysis solution flow path. The dialysis unit itself is held in a bracket which defines the valving system by means of a longitudinally movable and clampable retention member for bearing against the top of and holding the dialyzer member.
