Abstract
Abstract An endotracheal tube introducer comprising a rigid hollow mouth piece of greater diameter than the endotracheal tube being inserted thereinto, and an elongated member secured to and extending longitudinally away from the mouth piece, the elongated member comprising at least one guide rib extending longitudinally along the length of the elongated member away from the mouth piece and relatively thin pliable film pleated longitudinally and secured to the at least one guide rib and forming with the at least one guide rib, when the film is unpleated, an enclosed tubular structure for guiding the endotracheal tube into the trachea.
