ABSTRACT:
An esophageal tracheal intubator airway device which allows rapid blind access to the larynx and esophagus of a patient for lung ventilation, stomach suctioning, fiberscopic examination of the upper respiratory and upper gastrointestinal tracts, and passage of an endotracheal tube into the trachea. The device has a conical positioning element which conforms to the base of the throat beneath the epiglottis and an elongate tubular esophageal conduit which extends through the positioning element and rearwardly therefrom in an arcuate curve. The esophageal conduit is sized to allow passage of a gastric suction tube and related medical instruments therethrough into the patient's esophagus. A laryngeal channel extends inwardly from the positioning element proximal end and curves outwardly to define an opening through the side wall of the positioning element. The channel is sized to allow passage of a cuffed endotracheal tube and related medical instruments therethrough into the patient's larynx and trachea. An inflatable tubular ring secured to the positioning element side wall surrounds the opening and when inflated, forms a sealing relation around the patient's laryngeal inlet while causing the positioning element to back out relative to the throat a sufficient distance for a lip at its proximal end to lift the tip of the epiglottis up and out of the way of the side wall opening.
