Aseptic irrigation syringe

A flow control apparatus for providing selective fluid communication with physiological organs, comprising:

• a nozzle structure including a plurality of discrete ports for connection to a corresponding plurality of separate fluid conduits;
• syringe means having a fluid chamber for containing and discharging fluid in communication with at least one of said conduits;
• two valve members having respective engaged surfaces relatively rotatable to provide valving action, said valve members including a first valve member having a plurality of through apertures respectively communication with said nozzle ports and a second valve member having a through passageway communicating with said syringe chamber, said value members being selectively adjustable relative to at least one of said apertures to enable fluid flow between said respective nozzle port and said syringe chamber;
• and clamp means for applying axially directed opposing forces on said valve members in order to establish a fluid-tight seal between said engaged surfaces;
• wherein said claim means comprises cushion means for resiliently exerting said opposing forces on said respective valve members;
• and wherein said cushion means comprises a resilient member engaging said first valve member and having a plurality of through passageways in fluid communication with said respective apertures.
