Spare Insert for Amer. Mac. Laryngoscope F/O/I/T #4 134mm

Clinical Application

This spare blade insert restores the optical illumination and blade geometry of a #4 American Macintosh laryngoscope used for direct laryngoscopy and endotracheal intubation. The #4 size is intended for larger adult patients and for clinical settings where a full-sized Mac blade is required to obtain an adequate view of the glottis during routine and difficult airway management in operating rooms, emergency departments, intensive care units, and ambulatory surgery centers.

Design & Configuration

The Macintosh blade geometry provides a gently curved profile designed to lift the epiglottis indirectly and expose the glottic opening. A spare insert configured for fiber-optic illumination aligns with the handle's light transmission pathway to restore consistent, shadow-free illumination at the distal blade. Replacing a worn or damaged insert maintains blade contour, tip integrity and optical alignment—factors that directly affect visualization, first-pass success of intubation, and patient safety.

Instrument Specifications

• Pattern: American Macintosh (Mac) #4
• Length: 134 mm
• Fiber-optic compatible: yes (F/O alignment for handle illumination)
• Intended use: adult airway management / direct laryngoscopy
• Reusable component: designed for repeated clinical use and reprocessing

Material & Construction

Constructed to the clinical standards of reusable laryngoscope components, the insert is compatible with fiber-optic illumination systems common to American-style Mac handles. Materials are selected for durability and compatibility with hospital reprocessing; stainless steel blade construction and integrated fiber-optic elements are standard for this instrument type. Surface finish and joint tolerances are important for reliable mating with the handle and for preventing light loss at the optical interface.

Quality & Compliance

Manufactured by FDA-registered OEM facilities and produced under strict quality control standards.

Brand Comparison
