ABSTRACT:
The blade of a laryngoscope is made of non-metallic material such as plastic so that it can be economically disposed of after each use. Further, it includes a flexible portion which will protect a patient's teeth as a consequence of the unconscious tendency to encroach upon the patient's upper teeth by using them as a fulcrum for the blade in exposing the larynx in order to insert an endotracheal tube. A light source is located in the handle of the laryngoscope rather than the blade and a light conductor is held by the blade for optically conducting light from the source in the handle to an exit point along the blade for viewing the larynx.
