Cassette for a flow control apparatus

Abstract

A cassette for use with a pumping apparatus having a pumping system for engaging a pump set includes a cassette body configured for releasable attachment to the pumping apparatus to mount the cassette on the pumping apparatus. The cassette body has at least one mounting formation. At least one identification member is mounted on the cassette body by the mounting formation of the cassette body. The identification member and mounting formation are formed to mount the identification member in any one of a plurality of predetermined orientations. Each predetermined orientation indicates a different functional configuration of the pump set.
