ABSTRACT:
An improved laryngoscope and its method of use are disclosed herein. The laryngoscope includes a handle and a blade separate from the handle. The blade is engagable with the handle for selective movement between an inoperative position and an operative position. A locking mechanism is provided integrally with the laryngoscope which is selectively movable between an unlocked position, in which the blade remains movable between its inoperative and operative positions, and a locked position, in which, upon movement of the locking mechanism to the locked position while the blade is in its operative position, thereafter fixes the blade in the operative position until such time that the locking mechanism is moved to the unlocked position.
