A manifold assembly useful in patient ventilation/aspiration systems includes a stop cock valve with a hollow stem and a transverse slot arranged to permit the stem to be rotated between open and closed positions. In both positions, a ventilating pathway is maintained through the slot and the stem between ventilator and patient connection ports of the manifold. In open position the stem provides a travel pathway for a catheter between the patient connection port and an access port of the manifold. In closed condition, the stem seals this travel pathway.

[ What is claimed is:] [1.] A valve for use in a patient ventilation/aspiration system, comprising:a chamber, including first, second and third ports and a fluid path established between the first and third ports;a valve comprising a stem positioned within said chamber, said stem being constructed and arranged for movement between a first position in which said stem blocks fluid flow through said second port;a second position in which said stem provides a catheter travel pathway between said second and third ports, said catheter travel pathway comprising the fluid flow path throughout said third port;actuation structure linked to said stem and operable to move said stem between said first and second positions; andsaid valve being further constructed and arranged to avoid blocking fluid flow between said first and third ports.
