Abstract
An apparatus controls movement of fluids during an extracorporeal blood treatment session. A hollow cassette enclosure has a plurality of fluid input ports for receiving fluids into the enclosure and a plurality of fluid output ports for expelling fluids from the enclosure. Internal fluid passageways disposed within the hollow enclosure are provided for coupling together the fluid input ports, and the fluid output ports. At least one internal valve is disposed within the hollow enclosure for controlling movement of the fluid within the hollow enclosure. A filter is integrated into the cassette to filter the blood passing therethrough.
