The novel esophageal-endotracheal airway (10) has a shorter outer tube (9) and a longer inner tube (11). The airway is adapted to become inserted into either the trachea or into the esophagus. Each tube carries an expandable member (15a,15b) on its outer wall and near its distal end (12,9a). The outer wall of the inner tube and the inner wall of the outer tube form an annular passageway (9b) therebetween. Suction tubes can be inserted through this passageway for pumping out either the stomach or the lungs. This annular passageway (9b) cannot become totally occluded by any tissue from an adjacent body channel because the inner tube, as it exits from the annular passageway, acts to prevent tissue encroachment. By having the longer tube (11) inside the shorter tube (9), which terminates in the posterior pharynx, a suction tube can be advanced through the annular passageway exiting at the outlet of the shorter tube in an anatomical position to be advanced directly into the esophagus without any interruption of artifical respiration. |
