The automatic intubation device described herein consists of an endotracheal tube which can be inserted automatically into the trachea without the use of a laryngoscope or a physician skilled in its use and which will avoid obstruction on the way to the trachea and comprises a combination of: (1) a flexible guide having no more than a slight curvature in the length thereof and having a male adaptor or track running at least a substantial portion of its length and (2) the endotracheal tube to be inserted into the trachea which endotracheal tube may have a substantial amount of curvature therein and also has a slit extending from the advance or distal end of the endotracheal tube, extending longitudinally for a short distance along said tube and designed to fit onto the adaptor of the guide. The guide is introduced through the mouth and pharynx to the esophagus and the endotracheal tube is guided by sliding on the adaptor of the guide to where it leaves this adaptor beyond the epiglottus and at or before reaching the entrance to the esophagus at which point curvature of the endotracheal tube bends it toward and into the trachea.
