The Airway Intubator serves two purposes: as an oropharyngeal airway and, should the need arise, an endotracheal tube can be passed through the center of the airway intubator into the trachea without the need for further instrumentation.

Sykes, in 1937, described a divided airway made of aluminum; following the introduction of the endotracheal tube, both halves of the airway were removed leaving the endotracheal tube in place. A plastic airway, as designed in the 1970's by Berman, consisted of a tunnel along its whole length so that an endotracheal tube was compelled to follow this pathway.

With the advent of plastic endotracheal tubes with a relatively fixed radius of curvature, the airway intubator has been more successful than its predecessors, both as an oropharyngeal airway and as a means of intubating the trachea.
