Macintosh Laryngoscope Blade fibre optic #4, 133mm

Clinical Application

This curved Macintosh blade with integrated fibre optic illumination is intended for direct laryngoscopy to visualize the glottic opening and facilitate orotracheal intubation in adult or large-airway patients. The size #4 length provides the reach needed to engage the vallecula and indirectly lift the epiglottis for improved glottic exposure during routine and difficult airway management.

Design & Configuration

The Macintosh curved geometry positions the blade tip in the vallecula to achieve an indirect lift of the epiglottis, a technique commonly used for routine intubation. Integrated fibre optic illumination delivers continuous, evenly distributed light along the blade to improve sight lines down the airway without relying on a separate bulb at the tip. The longer #4 blade length offers additional reach and working distance for larger patients.
