Spare Insert for Wisconsin Laryngoscope F/O/I/T #4 137mm

Clinical Application

This spare insert is a replacement blade for Wisconsin-style laryngoscopes used in direct laryngoscopy and endotracheal intubation. Sized as a #4 (137 mm), it is intended for adult airway management where a larger blade provides the reach and exposure needed for visualization of the glottic opening. It is supplied as a serviceable insert so teams can rapidly replace a worn or damaged blade during preop preparation or between cases to maintain reliable illumination and optics.

Design & Configuration

The insert is configured to mate with Wisconsin-pattern laryngoscope handles and accommodates fiber optic illumination on FO-capable systems. The 137 mm blade length provides extended reach for adult anatomy while preserving the Wisconsin blade geometry that facilitates tongue displacement and line-of-sight exposure. As a spare insert, it supports quick removal and replacement to minimize instrument downtime in clinics, ambulatory surgery centers, and hospital ORs.
