Abstract
Abstract An endotracheal intubation device includes an inner flexible guide tube and an outer tube. The guide tube has a blunt end, an opened end, and an opening adjacent the blunt end which is adapted for passing a gas therethrough. The outer tube has open ends and is adapted for sliding and telescoping passage over the guide tube. An inflatable cuff, which is adapted for engagement with the trachea, is adjacent a distal end of the outer tube. The guide tube is inserted into a passageway of the patient. After determining that the guide tube is in the trachea, the outer tube is slid over the guide tube. Then, the guide tube is removed from the outer tube.
