  • Patent number: 4840173
    Abstract: An endotracheal tube having dual passages provided by the merging of a ventilation tube and a suction tube. The ventilation tube is adapted to project into a patient's trachea to the position of the carina anterior. An inflatable cuff surrounds the ventilation tube and prevents passage of fluids to and from the lungs. The suction passage terminates at the cuff with openings into the suction passage for suctioning secretions that pool around the cuff. The tubes as merged enable entry of the dual passages into the trachea past the vocal cords. As protruded from the patient's mouth, the tubes are separated to be connected to the respective ventilation machine and secretion suction machine.
