ABSTRACT:
An improved laryngoscope blade, where the lingual side of the blade, being the side that is presented against a patient's tongue during examination, defines a concave area which defines a cavity which allows the patient's tongue to be cradled during the examination, and where the curved descending sides of the blade proiaote and urge the tongue into the cavity area, and prevent the tongue from flattening out sufficiently so as to curve over onto the top side of the blade, where the view of the patient's airway would be obstructed.
