Abstract
A pressurized intravenous fluid delivery apparatus that operates as a closed system incorporating a waste component to avoid the accidental injection of air. The apparatus comprises a fluid reservoir under pressure, a manifold with a series of stopcock, an exhaust means in fluid connection with both the fluid reservoir and the manifold by means of a dual check valve, and a cannula and syringe means for injecting fluid into a patient. The closed system facilitates the flushing of blood and air out a catheter without the necessity of disconnecting any part of the apparatus and thereby risking exposure to air or risking physician contact with body fluids. The system is useful for delivering any quantity of one or more fluids under pressure, while avoiding the injection of air.
