Abstract
A medication infusion system having a disposable cassette including a piston pump and active valves for installation on a main pump unit including a mechanical drive system for operating the cassette is disclosed which has a unique system for loading the cassette onto the main pump unit and latching the cassette in place on the main pump unit. The cassette includes a slide latch which closes the fluid path when the cassette is to be installed, the slide latch only being opened when the cassette is properly installed on the main pump unit with the valve actuators of the main pump unit preventing fluid freeflow. Latching the cassette in place causes a latch head on the main pump unit to grasp the piston on the cassette in a driving relationship.
