摘要： In a laryngoscope, a blade for displacing a person's tongue in order to facilitate insertion of an endotracheal tube into the person's trachea includes a distal portion for insertion through the person's mouth and into the person's oropharynx and an elongated portion extending from the distal portion; the elongated portion is substantially wider than the distal portion and includes an inner side that is disposed for contacting and displacing the person's tongue when the distal portion is inserted into the person's oropharynx; and the inner side of the elongated portion is laterally contoured for restraining the person's tongue in a relatively centered position while the tongue is being displaced. The blade and the handle of the laryngoscope are injection molded in the same mold and may be of the same plastic material. Preferably the blade is transparent for transmitting light from a light source in the handle. The transmitted light is emitted from the blade to illuminate the person's oropharynx when the distal portion is inserted into the person's oropharynx. The handle includes a portion that extends directly from the blade and is curved longitudinally so that the handle can be gripped at different angles with respect to the blade. Preferably, the blade also is curved longitudinally.
