ABSTRACT:
A peristaltic pump comprising a housing (19), including a base (21), a resilient tube (27) and a peristaltic pumping fingers (31) carried by the supporting structure. The tube (27) is positionable on the base (21) in a proper position and an improper position. In the proper position, the peristaltic pumping fingers (31) can properly progressively squeeze the tube to pump a fluid through the tube and in an improper position. A door (23) is mounted on the housing (19) for movement between an open position and a closed position. A latch (25) includes a pivotable latch member (51) on the door (23) and a fixed latch member (55) on the housing (19). The pivotable latch member (51) is movable between a latching position in which the door (23) is locked in the closed position and a releasing position in which the door (23) is not locked in the closed position. If the tube (27) is in the improper position, the pivotable latch member (51) is prevented from being placed in the latching position.
