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 (13) 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 (11) in exposing the larynx in order to insert an endotracheal tube. A light source (24) is located in the handle (10) of the laryngoscope rather than the blade (11) and a light conductor (15) is held by the blade (11) for optically conducting light from the source in the handle (10) to an exit point along the blade (11) for viewing the larynx. |
