An endotracheal tube of the inflatable cuff type and having a suction chamber adjacent the upper side of the cuff. The suction chamber is in the shape of a bulge having four ports equally spaced about the periphery of the bulge and facing upwardly. Suction applied to the chamber will extract fluids from the trachea above the cuff without invaginating the tracheal mucosa. Medicinal fluids may also be introduced into the trachea via the suction chamber and ports. |
