Amer.Macintosh Laryngoscopeblade F/O Int/T 134mm, #4

Clinical Application

Designed for direct laryngoscopy during airway management, this curved Macintosh blade size #4 provides the reach and blade geometry commonly used for intubation in larger adult patients. The Macintosh curvature permits indirect elevation of the epiglottis by positioning the blade tip in the vallecula, facilitating visualization of the glottic opening and passage of an endotracheal tube. Integrated fiber-optic illumination improves illumination of the oropharynx and glottic aperture, aiding visualization in routine and challenging lighting conditions.

Design & Configuration

The classic Macintosh profile features a smooth, anatomically curved blade that follows the posterior pharyngeal contour to create a line of sight to the glottis when properly positioned in the vallecula. A longer #4 blade delivers additional depth and a wider flange suitable for patients with larger oral and pharyngeal anatomy. Fiber-optic transmission routed through the blade provides bright, focused illumination along the working length to reduce shadows and enhance contrast during tube placement.
