Abstract: A fluid infusion pump includes a disposable cassette (12) having an inlet (16), an outlet (24), and a fluid chamber (36) between the inlet and the outlet. There is a fixed wall (180) of the fluid chamber and a movable wall (182) of the fluid chamber. A pump body (26) receives the cassette in a fixed operating relationship such that an actuator (62) in the pump body is activatable for reciprocal advancement and retraction with respect to the cassette and is adapted to confront the movable diaphragm when the cassette is received in the pump body. There is a detachable coupling (44) between the actuator mounted in the pump body and the movable wall so that fluid is expelled from the fluid chamber on advancement of the actuator and positively drawn into the fluid chamber upon retraction of the actuator.
