Abstract
A tracheal intubation guide having a tubular member with a curved forward end shaped to follow the curvature of the back of the tongue and throat of a patient, and a rear end for projecting out through the mouth of the patient, and an anterior guide surface extending along at least part of the length of the member to its forward end for guiding the member into the throat into a position opposite the opening into the larynx. The tubular member has a through bore for holding an endotracheal tube, and the guide surface has a forward edge of concave shape for engaging the front of the epiglottis and seating over the hyo-epiglottic ligament when the member is accurately positioned. Correct positioning can be detected by external palpation of the neck.
