  • Patent number: 5178132
    Abstract: An improved laryngoscope having a curved laryngeal blade and a chin-engaging member are provided to uniquely employ the chin of a patient as a fulcrum for enabling controlled pivotal movement of the blade. Not only is the laryngeal blade pivotable relative to the chin-engaging member through the operation of plier-like handles, but the blade is also telescopically adjustable to enable use on individuals of varying sizes. A U-shaped blade which is both curved and rounded and a torroidally-shaped chin pad further enhance the operation of the laryngoscope.
