Spare Insert for Macintosh Laryngoscope F/O/I/T #4 133mm

Clinical Application

This spare insert is a replacement Macintosh size #4 blade designed to restore full laryngoscopic function for adult patients with larger airway anatomy. The curved Macintosh profile is intended for indirect elevation of the epiglottis to expose the glottic opening during orotracheal intubation and routine airway assessment. Integrated fiber-optic illumination delivers consistent light along the blade to minimize shadows and improve visualization during placement in operating rooms, emergency departments, intensive care units, and ambulatory surgery centers.

Design & Configuration

The Macintosh curved geometry provides a familiar fulcrum for lifting the vallecula and exposing the vocal cords without directly manipulating the epiglottis. At 133 mm length, the blade offers the reach required for adult airways while maintaining a smooth, low-profile flange to facilitate passage of the endotracheal tube. The spare insert form allows simple replacement of a worn or damaged blade component without replacing the entire laryngoscope assembly, reducing downtime and lifecycle cost. The fiber-optic channel is integrated to provide inline illumination while maintaining a slim blade cross-section to limit oropharyngeal obstruction.
