Macintosh Laryngoscope blade F/O, Fix/T 107mm, #3

Clinical Application

Size 3 Macintosh blades are the workhorse for adult airway management. This curved blade geometry is intended to be positioned in the vallecula to facilitate indirect elevation of the epiglottis and expose the glottic opening for direct laryngoscopy and orotracheal tube placement. Fiber-optic illumination along the blade improves visualization of the vocal cords in low-light or blood-tinged fields, helping to reduce the need for repeated manipulations during routine and semi-difficult intubations.

Design & Configuration

The Macintosh curvature provides a predictable lever arm to lift the base of the tongue and expose the glottis without directly lifting the epiglottis, which many clinicians find reduces trauma and improves view. A 107 mm working length with a size 3 profile offers sufficient reach and depth for standard adult anatomy while maintaining tactile control during insertion and maneuvering. The fiber-optic illumination is routed through an integrated channel to deliver focused, shadow-reduced light at the blade tip; the fixed attachment enhances stability of the light path and reduces intermittent loss of illumination associated with removable bulb assemblies.

Instrument Specifications
