Abstract
Disclosed are devices and methods for the control of body fluid flow in the extracorporeal treatment of body fluid. Body fluid flow through on of a body fluid flow circuit 10, 50, 60 100, or 250 is controlled by alternatingly applying vacuum pressure and positive pressure to the circuit through a pumping chamber 30, 51, 66, 102, or 200 coordinated with flow control valves 40, 42, 44, 62, 114, 116, 118, and 120 to effect a net downstream flow of body fluid through the circuit.
