Abstract
A laryngoscope comprising a disposable blade unit including two full length blades releasably interconnected along the length thereof to define a tubular passage. A reusable handle unit removably receives one end of the blade unit and retains the blades thereof. The blade unit includes an inflatable balloon expandable against the roof of the mouth to center an inserted laryngoscope and effect movement thereof against the tongue and epiglottis. A pair of suction channels are defined through the blade unit and communicated with the interior of the tubular passage at the leading end thereof. The handle unit includes means for communicating the balloon and suction passages with sources of positive and negative air pressure respectively. The handle unit also mounts illuminating means and a selectively usable adapter for accommodating a hand manipulable air bag for emergency respiration directly through the laryngoscope.
