Spare Insert for Macintosh Laryngoscope F/O/I/T #3 108mm

Clinical Application

This spare Macintosh #3 insert is intended for direct laryngoscopy to facilitate orotracheal intubation and airway management in adult patients. The curved Macintosh geometry is positioned in the vallecula to achieve indirect elevation of the epiglottis and optimize glottic exposure. Having a dedicated spare insert on hand reduces equipment downtime during busy operating rooms, emergency departments, intensive care units, and ambulatory surgery centers.

Design & Configuration

The classic curved Macintosh profile provides predictable interaction with pharyngeal anatomy: the blade tip seats in the vallecula while the flange directs the endotracheal tube during intubation. The 108 mm blade length (#3) is selected to balance reach and control for the majority of adult patients. The F/O designation denotes fiber‑optic illumination compatibility, which improves light transmission along the blade and reduces shadowing compared with lamp‑only systems. As a spare insert, the component is designed for quick installation and replacement within a reusable laryngoscope assembly, supporting rapid turnover and equipment maintenance workflows.
