Abstract
An aerosol delivery system includes an endotracheal tube with a sub-port having a sufficient diameter to permit the passage of a sub-port tube therethrough. The sub-port tube passes within the interior of the endotracheal tube via the sub-port and includes a passageway that terminates in an atomizer nozzle at the distal end of the sub-port tube. The atomizer nozzle and the endotracheal tube are integrally connected to one another at a distal end base outlet of the endotracheal tube. A delivery conduit having an atomizer connector at its distal end is adapted to be connected to a canister for delivering fluid under pressure. The delivery conduit has a sufficient length to pass within the sub-port tube to lockingly engage the atomizer nozzle atomizer, whereby fluid delivered under pressure from the canister flows to the atomizer nozzle causing an aerosol mist to be dispensed outwardly from the base outlet of the endotracheal tube.
