1. A system for delivering fluid to a patient, comprising:

  • a fluid conduit through which fluid is delivered to the patient;

    a pumping mechanism having a plurality of movable pumping devices guided by at least one guide device to control the direction of movement of the pumping devices and a drive means rigidly mounted to the guide device and operative on the pumping devices to move the pumping devices in the guide device through a predetermined range of motion;

    a rigid base mounted so as to position the fluid conduit between itself and the pumping mechanism; and

    a mounting linkage connected to the pumping mechanism to mount the pumping mechanism in a predetermined orientation relative to the rigid base and in relation to the fluid conduit so that the pumping devices move into and out of contact with the fluid conduit to move fluid through the conduit, the linkage configured to allow movement of the pumping mechanism relative to the rigid base, but to constrain such movement to the predetermined orientation.
