Abstract: A disposable pumping cassette having an integral auxiliary flow control and pressure monitoring member is used for delivering a medicinal fluid to a patient. The pumping cassette includes an elastomeric member mounted in a rigid body having an inlet and an outlet. An inlet valve and an outlet valve on the cassette are opened, and the flow control is positioned to allow the medicinal fluid to flow freely through the cassette, priming it before the outlet is connected to the patient. The cassette is then coupled to an associated pump driver, closing the flow control to disable free fluid flow through the cassette, and the outlet to the cassette is coupled in fluid communication with the patient's body.

Abstract: A pack (10) for carrying an IV bag (12) and an ambulatory IV pump (16). The pack includes an inner back (30) and an outer back (32) that are sewn together on three edges to form a pocket (38) in which a plastic plate (40) is inserted to provided rigidity. A pair of inner flaps (64, 66) secure the IV bag against the back of the pack. Several straps (42, 50, 52, 62) also secure the IV bag in place, limiting its lateral and longitudinal movement relative to the back of the pack. Outer flaps (70, 72) overlap to enclose the IV bag. One of the outer flaps includes a pocket (14) in which the IV pump (16) is carried. The flaps and straps are secured by engaging a hook material attached to one surface of the strap or flap to a loop material attached to another surface.

The pumping cassette includes an elastomeric member mounted in a rigid body having an inlet and an outlet.

The cassette is then coupled to an associated pump driver, closing the flow control to disable free fluid flow through the cassette, and the outlet of the cassette is coupled in fluid communication with the patient's body. The medicinal fluid is drawn into a pumping chamber formed in the rigid body as a plunger of the associated pump driver is drawn up from the elastomeric membrane at a recess formed in the rigid body.

Abstract: A push button flow stop is mounted on a disposable infusion pumping cassette provided for use with a drug infusion pump. The flow stop is operative to enable or to block fluid flow through the cassette in a first mode and to monitor fluid pressure in the cassette in a second mode.
