Abstract: A novel method and apparatus for directing air flow and for removing internal secretions within an intubated patient is disclosed. In one respect, the invention contemplates an air flow assembly including a conduit coupling assembly coupled to an expansible conduit. The conduit coupling assembly includes a housing with an upper flow connector and a lower flow connector; a recess at its lower end; and an annular, valved partition defining an annular chamber within the housing below the partition. The lower flow connector is configured to be connected to the upper or proximal end of an endotracheal tube so as to form an annular passageway between the endotracheal tube and the expansible conduit. The upper flow connector is adapted to receive air or other desired gas from a suitable source. The partition includes a one-way flow valve or other device for enabling flow of gas selectively through the housing.
