Macintosh Laryngoscope blade F/O, Fix/T 133mm, #4

Clinical Application

Curved Macintosh size 4 blades are used in direct laryngoscopy to expose the glottic inlet during orotracheal intubation in larger adult patients. The curved profile is intended to be advanced into the vallecula to lift the epiglottis indirectly and improve line-of-sight for endotracheal tube placement. Integrated fiber-optic illumination enhances visualization of the oropharynx and laryngeal structures during routine and difficult airway management.

Design & Configuration

The Macintosh geometry features a gently curved flange that displaces the tongue and provides a working channel to guide the tube. The 133 mm blade length increases reach for patients with deeper oral cavities or larger anatomy. Fiber-optic (F/O) illumination runs within the blade to provide bright, evenly distributed light at the distal edge, reducing shadows that can obscure the glottis. "Fix/T" indicates a fixed terminal mounting style for attachment to compatible laryngoscope handles; confirm handle compatibility prior to purchase.
