Abstract

A flow control apparatus for providing selective fluid communication with physiological organs includes a nozzle structure for multiple conduits, a syringe having a fluid chamber for containing and discharging fluids in communication with the nozzle structure, two valve members having respective engaged surfaces relatively rotatable to provide valving action, and a clamp structure which forces the valve members together to establish fluid-tight seal between their engaged surfaces. The first valve member has a plurality of through apertures respectively communicating with separate fluid ports in the nozzle, and the second valve member has a through passageway communicating with the syringe chamber; the passageway is further selectively communicatable with at least one of the apertures in the first valve member to enable fluid flow between the respective nozzle port and the syringe chamber.
