Pressure actuated flow control device for gravity iv sets

Abstract

A flow control device may include a housing having a primary valve body defining a primary inlet and an outlet of the flow control device, a secondary valve body defining a secondary inlet of the flow control device, and a chamber defined by an inner circumferential surface of the housing. The primary and secondary inlets may share a common central axis, and a central axis of the outlet may be perpendicularly disposed relative to the common central axis. The chamber may extend between the primary and secondary valve bodies for fluidly connecting the primary and secondary inlets with the outlet. The flow control device may further include a valve member reciprocally mounted in the chamber to (i) block fluid communication between the secondary inlet and the outlet when fluid pressure into the primary inlet is higher than fluid pressure into the secondary inlet, and (ii) block fluid communication between the primary inlet and the outlet when fluid pressure into the secondary inlet is higher than fluid pressure into the primary inlet.
