Abstract: A popoid connector for use with other medical devices such as tracheal tubes, intubation tubes and aspiration and ventilation systems comprises a plurality of saucer shaped members each having a first portion and a second portion to form a corrugated portion along the connector. On side of each of the saucer shaped members is provide with at least one circumscribing reinforcing rib to provide additional structural support for the popoid connector. The reinforcing ribs are integrally formed with the popoid connector. The reinforcing ribs inhibit transverse collapsing of the popoid connector add rigidity to the popoid connector when the popoid connector is in a bent position.

Abstract: An improved respiratory suction apparatus catheter includes a manifold for attachment to the distal hub of an endotracheal tube to form a ventilation circuit, a catheter tube which is displaceable through the manifold and into the endotracheal tube to suction secretions from the tube and lungs, and a valve mechanism disposed adjacent the ventilation circuit to minimize the draw of air from the ventilation circuit of a patient while the catheter is being cleaned. In a preferred embodiment of the invention, the catheter is cleaned more thoroughly than in the prior art while simultaneously drawing little or no air from the patient's ventilation circuit.
