A dual bladed laryngoscope (10) for simplifying intubation. There is a grip portion (14h) and handle (18) for opening and closing the blades, and laryngoscope (10) is pivotally hinged on one side of the blades for easy removal while an oxygen source remains attached to the endotracheal tube. An esophageal obturator (12c) and ramp (20d) formed by arytenoid bumper (20) ensure proper tube placement by deflecting the tube into the trachea while blocking the esophagus. The upper blade (14) has an optional tongue guard (14i), and a suction conduit (22) is built in or secured to either the lower blade (12) or the upper blade (14) for suctioning secretions or emesis while intubating. A suction break (22d) allows a finger of the hand holding the laryngoscope (10) to control the presence and intensity of suction while the opposite hand simultaneously inserts the endotracheal tube into the trachea. |
