A disposable manifold and valve for fluid processing are claimed in which a manifold provides a plurality of sterile paths for directing the flow of fluids. A rotatable valve employs a cam to control the flow of fluids through the manifold. The valve and manifold system are suited for the processing of blood and particularly for the washing of shed blood retrieved during surgery.

A valve for controlling biological fluid flow comprising: (a) a manifold having a fluid junction and a plurality of fluid pathways in the manifold through which fluid can flow into and out of the junction; and (b) one flexible tube coupled to a respective one of the pathways; (c) a retainer having a

A valve for controlling biological fluid flow comprising: (a) a manifold having a fluid junction and a plurality of fluid pathways in the manifold through which fluid can flow into and out of the junction; and (b) one flexible tube coupled to a respective one of the pathways; (c) a retainer having a bearing surface, the manifold being secured in a predetermined position in the retainer and the tubes also being secured in a predetermined position against said bearing surface on said retainer, and (d) a rotatable cam having a spindle loaded by a spring, said cam not in fluid communication with the pathways such that rotation of the cam relative to the manifold closes and opens selected tubes contacting the cam and bearing surface to control the flow of fluid through the junction; (e) a support member; and (f) a cover on said support member which, when the manifold retainer and tubes are loaded into the support member and said cover is closed, forces the manifold and retainer against the cam, resulting in compression of the spring.
