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.
Catheter depth finding features and internally walled manifold structure
for direction of respiratory therapy fluids particularly useful for
neonatal patients are presented.
