Abstract

A medical infusion system has a pump and cassette (16) combination for conducting fluid or semisolids from an upstream portion to a downstream portion of the system. The cassette includes a rigid enclosure (17) defining a pumping chamber (18) and has a window (25) with a diaphragm (27) spanning the window. The diaphragm is engaged by means on the pump for varying the volume of the pumping chamber. The configuration of the cassette is such that the outlet (23) for the pumping chamber is located at the top of the pumping cavity and the internal configuration of the cavity causes gas bubbles to migrate to the outlet opening. A passage (29) communicates between the outlet opening and a location proximate to the lower portion of the cassette. Alternatively, the outlet opening may extend vertically or horizontally from the top of the pumping chamber and communicate with a flexible conduit.
