Abstract
Abstract An adjustable oral airway comprising a superior section and inferior section joined at their inner ends by a hinge member, and slidably secured relative to each other at the mouthpiece end, as by a tongue and groove slidable joint. The superior and inferior sections may be spaced a greater or a lesser distance from each other by means of sliding the upper and lower sections of the mouthpiece to improve ease of insertion and removal and to expand or reduce the pharynx, lifting the epiglottis and improving the breathing ability of an unconscious patient.
