Abstract

A rapid infusion system for the intravenous delivery of fluids at standard and rapid flow rates. The system includes a pump assembly, a drive assembly to power the pump, and a fluid containment system that keeps the infused fluid out of direct contact with the pump assembly and that is preferably disposable and removable. In one embodiment the drive assembly includes a differential drive that interacts with more than one motor. In one embodiment, the pump assembly includes a roller pump and the pump chamber is a collapsible, preformed tube that is preferably attached to a pump cartridge frame. Optionally, the system includes a self-leveling drip chamber and the fluid containment system is disposable and includes a pump cartridge containing the drip chamber and the pump chamber, I.V. tubing, outlet infusion tubing, and a heater cartridge.
