ANTI-FREE-FLOW VALVE ASSEMBLY WITH FLOW BYPASS

Abstract:

An enteral feeding valve assembly includes a housing assembly that is fluidly coupled with an upstream line and a downstream line. A diverging conduit inwardly extends from an inlet and a primary conduit inwardly extends from an outlet of the housing. The diverging conduit splits into a bypass conduit and a flow-through conduit. The flow-through conduit is fluidly coupled with the primary conduit by a check valve. A plunger valve includes one or more plunger conduits and moves in a first direction to fluidly couple the inlet with the primary conduit and the outlet via the bypass conduit and the one or more plunger conduits. The plunger valve moves in a second direction to de-couple the inlet from the primary conduit and the outlet via the bypass conduit and the one or more plunger conduits. The flow-through conduit directs the fluid to the outlet through the check valve.
