  • Patent number: 4314551
    Abstract: A laryngeal blade useful for displacement of the epiglottis has a fixed blade part projecting from the handgrip and having a tongue-diverting wall which supports a light source projecting toward the forward end of the blade. A movable blade part is hinge-mounted to the fixed blade part at its aft end and extends along the fixed blade part, on its side opposite the tongue-diverting wall, to beyond the end of the fixed blade part. A lever handle fixed to the aft end of the movable blade part is utilized to pivot the movable blade part to displace the epiglottis, exposing the entrance to the trachea, such as for intubation.
