ABSTRACT:
A cassette is described for use in an intravenous delivery system having a pump. The volume of a main chamber defined by the cassette body is varied and unidirectional inlet and outlet valves maintain the fluid direction into and out of the main chamber. In the operating position of the cassette, the outlet valve is positioned to be in communication with any gas present in the main chamber. For the purpose of accumulating air from the upstream portion of the intravenous delivery system in which the cassette is used, a prechamber is positioned above the inlet port communicating therewith.
