Amer. Macintosh Conventional Laryngoscope blade 134mm, #4

Clinical Application

This curved Macintosh blade is sized for adult and large-adult airways and is designed to facilitate direct laryngoscopy for endotracheal intubation. The #4 length provides additional reach for patients with deeper oral cavities or when a longer blade is required to achieve an adequate line of sight to the glottic inlet. It is intended for use by anesthesia, emergency, and critical care teams in operating rooms, procedure suites, emergency departments, and intensive care settings.

Design & Configuration

The Macintosh geometry features a smoothly curved profile that seats in the vallecula to produce an indirect lift of the epiglottis, exposing the vocal cords without directly manipulating the epiglottic edge. The longer #4 blade increases distance from the oral aperture to the glottis, which can improve visualization in larger patients but may require additional care in limited-mouth-opening or pediatric cases. The conventional blade interfaces with standard laryngoscope handles and illumination systems used in routine airway management.
