Spare Insert for Miller Laryngoscope F/O/I/T #4 182mm

Clinical Application

This spare insert restores or replaces the optical/illumination element of a size 4 Miller laryngoscope blade. Intended for use during direct laryngoscopy for airway management, it helps re-establish reliable light transmission to the blade tip and maintain clear visualization of the glottic inlet during adult intubation. Keeping spare inserts on hand reduces equipment downtime and supports continuity of care in operating rooms, ambulatory surgery centers, emergency departments, and anesthesia practice areas.

Design & Configuration

The straight Miller blade geometry lifts the epiglottis directly; the 182 mm length corresponds to the #4 blade intended for larger adult airways. As a dedicated insert for F/O/I/T-type blades, the component is configured to sit within the blade optical channel and align the fiber-optic light path to the distal tip. Proper seating and alignment preserve the blade's visual axis, minimize shadowing, and restore the intended field of view without altering blade handling or patient exposure.
