ABSTRACT:
An improved laryngoscope of the type having a stationary handle, a stationary blade affixed to the stationary handle, a tip pivotally attached to the stationary blade, a movable handle pivotally attached to the stationary blade, and an arm pivoting the tip downwardly when the movable handle is moved towards the stationary handle depressing the epiglottis. The improvement includes a movable blade pivotally attached to the stationary blade and affixed to the movable handle so as to allow the movable blade to pivot away from the stationary blade when the movable handle is moved towards the stationary handle and spread the posterior tissue defining the superior opening of the larynx away from the epiglottis simultaneously as the tip depresses the epiglottis and both thereby opening up the trachea exposing the larynx, and a lock locking the movable blade in a desired positioned by locking the movable handle affixed thereto.
