ABSTRACT:
Instrumentation comprising an automatic positioning and retracting laryngoscope, detachable periscope, and method of endotracheal intubation are disclosed. The device comprises an anterior blade which contacts the tongue and a posterior blade which contacts the hard palate. The blades are moveable apart in a prescribed manner according to the shape of an arm. Manually opening the device causes the airway soft tissue retraction and epiglottic lifting required for visualization of the trachea. The blades remain open via a releasable racheting device. An illuminating periscope can be snapped onto the device allowing indirect tracheal visualization. The entire assembly is sized to fit beneath an airway mask to allow ventilation during the entire intubation process.
