A peristaltic pump is disclosed which facilitates quick loading of a compressible tubular conduit through which fluid may be pumped. The pump includes a pair of reaction members pivotally mounted on a base plate for movement between open and closed positions relative to a rotor, the reaction members being releasably retained in their closed positions by a locking plate. The compressible tube partially encircles the rotor and has its ends releasably engaged by clamping means which prevents axial movement of the tube and is adapted to accommodate tubes of different diameter.

A peristaltic pump comprising a base plate defining a generally planar mounting surface, a rotor rotatably supported by said base plate for rotation about an axis substantially perpendicular to said mounting surface, said rotor including at least one compression surface movable in a plane substantially parallel to said mounting surface, a pair of reaction members pivotally supported by said base plate for movement relative to said base plate between closed positions juxtaposed to said rotor and open positions spaced from said rotor, said reaction members defining cam surface means operative when said reaction members are in their said closed positions to maintain a compressible fluid flow tube in position to be engaged by said compression surface upon rotation of said rotor so as to effect a peristaltic pumping action on said tube, said reaction members facilitating loading and removal of said tube relative to said rotor when in their said open positions and exposing an outer surface of said rotor when in their said closed positions, and locking plate means mounted on one of said reaction members and selectively cooperable with the other of said reaction members to releasably retain said reaction members in their said closed positions, said locking plate means being adapted to cover said exposed outer surface of said rotor when in said retaining relation with said reaction members so as to prevent access to said rotor.
