ABSTRACT:
The invention is a self-retaining disposable laryngoscope having dual light conductive blades that open and lock apart laterally and/or radially. The invention has two curved blades: a tongue blade and a palate blade. These two blades may be separated and locked apart by a ratchet mechanism in the instrument's handle while they remain parallel. This provides a bite block, pushes down the tongue, and makes the invention self-retaining in the airway. The palate blade may be rotated about an axis in the handle of the instrument and locked in position by a ratchet mechanism to spread the distal ends of the blades. This lifts the palate and epiglottis and opens the airway.
