Abstract
In a pump chassis (,), spring-loaded members (,) engage a pumping cassette (,) to it in a predetermined position. The members each include pairs of latches (110,, 110,) that are each beveled to form a ramp so that the latches and associated members are forced outwardly to enable the pumping cassette to be seated within the pump chassis. The latches engage the pump cassette as it is seated, holding it securely. A release button (,) is attached to a spring-loaded shaft (,) that extends into the interior of the pump chassis. The shaft has a ramp formed on its inner end. When the user depresses the release button, the ramp rides under inwardly extending arms (,) provided on the members, forcing the members and attached latches to move outwardly. As the members move outwardly, the pumping cassette is released and readily removed.
