A fluid manifold includes a housing having a first inlet and an outlet and a plurality of inlets intermediate the first inlet and the outlet which are provided with check valve action to prevent retrograde flow through the valved inlets, yet allow individual inlets to pass fluid when the fluid pressure in any individual inlet exceeds that of the interior of the chamber by a predetermined cracking pressure, and retrograde flow through the first inlet is controlled by a flapper portion which may be biased to an open position to allow unrestricted flow from the first inlet to the outlet or configured so as to be in sealing contact with a valve seat in order to preferentially inhibit flow.

[ What is claimed is:] [1.] A fluid manifold for use in infusing medical fluids, comprising:a housing having a first upstream inlet and a downstream outlet and at least one retrograde flow checked inlet intermediate the first upstream inlet and the outlet, and a plurality of valve seats, each such valve seat associated with an inlet, and a chamber interconnecting the inlets and the outlet;a single resilient backcheck member confined within the chamber and deformably urged against at least one retrograde flow checked valve seat and providing individual check valve action at each of the plurality of valve seats, said resilient backcheck member having a backcheck flapper portion positioned adjacent said first upstream inlet, and retrograde flow through said first upstream inlet is prevented by closure of said backcheck flapper portion against a valve seat around said first upstream inlet, and wherein the housing comprises at least one support member disposed to urge the resilient backcheck member against at least one valve seat.
