1. A medical fluid pump apparatus for use with a fluid delivery set including a fluid reservoir, a delivery outlet, and tubing connecting the reservoir to the outlet, the apparatus comprising:

  • a pump;

    a housing on which the pump is supported, the housing including a shelf spaced from the pump and provided with a pair of spaced, transverse slots sized for receipt of the tubing of the fluid delivery set so that the tubing of the fluid delivery set may be received in the slots and placed in operative engagement with the pump;

    a latch supported on the housing for movement between a closed position in which the latch blocks the slots to prevent the removal of the tubing from the slots and an open position in which the latch exposes the slots to permit insertion and removal of the tubing,the latch being generally U-shaped, including a pair of legs spaced from one another by a distance equal to the spacing between the slots, each leg being sized for receipt within one of the slots so that when the latch is in the closed position the legs extend into and block the slots,wherein the latch is supported on the housing for pivotal movement about a support axis and for translational movement along the support axis relative to the housing; and

    a catch means for preventing the latch from being pivoted about the support axis when the legs are positioned at least partially within the slots and for allowing the latch to be pivoted after the latch has been translated along the support axis by a distance sufficient to remove the legs from the slots.
