The most popular of the straight types. The side of the flange is reduced to minimize trauma and the curve at the beak or tip is extended to improve lifting of the epiglottis. These improvements facilitate greater exposure of the larynx in difficult-to-intubate patients. The Macintosh Laryngoscope Blade . . . The Macintosh is the predominate model of the curved blade types. During laryngoscopy, the tip or beak of the blade is compressed into the angle formed by the base of the tongue and the epiglottis, indirectly raising the epiglottis.
