Abstract
A ventilating and aspirating apparatus for delivering respiratory gases to the trachea of a patient and aspirating congested lungs and breathing passageways includes a flexible catheter tube extendable into and withdrawable from the patient's trachea, a resilient pliable sheath lending a structural rigidity to the apparatus and receiving the catheter tube when withdrawn from the patient, a valve structure attached to the catheter tube which is slidable along the length of the sheath, a manifold structure and swivel mounting means to allow coaxial swivel motion of the components, and a collapsible/extendable sealing envelope structure arranged to cover components on the proximal side of the manifold.
