An improved laryngoscope blade is shaped similarly to a conventional blade except that a downwardly extending fin and lateral portion is not used. Rather an integral sleeve of plastic material is provided and receivable over the front portion of the blade in the manner of a stocking. This plastic sleeve has a solid downwardly extending fin portion and a lateral extending portion. The plastic cover or sleeve serves two functions: first, it removes the necessity of sterilizing the laryngoscope blade itself since the sleeve can be removed and disposed of after each use; second, the extended fin and lateral portion of the sleeve serves as a second surface to cushion contact of the blade with a patient's upper front teeth should these teeth be used unconsciously as a fulcrum when manipulating the blade to expose the larynx in order to facilitate insertion of an endotracheal tube.
