Abstract
A pressure pump for fluid in which tubing is wound about an orbitally movable pressure member inside of a sleeve member which is defined by a pair of pivotally mounted, substantially semi-circular jaws to permit opening and closing of the jaws about the pressure member to facilitate installation of tubing. Sliding gripper means may be carried by the pump and positioned to interact in one position with grippable means on the free ends of the jaws to hold them in closed relation, and for the sliding gripper means to be moved to a second position to permit the jaws to open. Simultaneously, the sliding gripper means can serve as a latch for a lid of the casing in which the pump is carried. Also the casing may have a partition with groove means having an enlarged portion for receiving joined connectors in the tubing, and a power source such as a battery may be attached to a removable portion of the casing in such a manner as to prevent accidental reverse installation of the battery.
