Spare Insert for Amer. Mac. Lary F/O/I/T #3.5 123mm

Clinical Application

This spare insert is a replacement Macintosh blade component intended for direct laryngoscopy to facilitate visualization of the glottis and placement of an endotracheal tube. Its Mac curved profile provides the classic geometry used to lift the epiglottis and expose the vocal cords, while the fiber‑optic compatible design supplies integrated illumination to improve visualization in variable lighting environments. The #3.5 (123 mm) length offers a mid‑to‑long blade option for a broad range of airway anatomies, making it suitable for use in operating rooms, emergency departments, intensive care units, and ambulatory surgery settings where rapid replacement of a damaged or worn insert is required.

Design & Configuration

The Macintosh curve is designed to follow the tongue and vallecula, enabling indirect elevation of the epiglottis for a direct line of sight to the glottis. As a spare insert, the component is configured for straightforward installation into compatible American‑style Macintosh laryngoscope systems, allowing facilities to replace only the blade insert rather than the entire instrument. The fiber‑optic channel runs along the blade to deliver distal illumination without external light sources, improving visualization during intubation and reducing shadows in the oropharynx. The blade geometry and length influence leverage, visualization angle, and distance to the glottic opening—factors clinicians consider when selecting the correct size for a given patient.

Instrument Specifications

• Instrument type: Laryngoscope spare insert / blade
• Pattern / model: American Macintosh
• Configuration: Fiber‑optic compatible spare insert
• Size: #3.5 (123 mm)
• Tip / jaw pattern: Macintosh curved blade profile
• Typical use: Direct laryngoscopy and endotracheal intubation

Material & Construction

Constructed from durable stainless steel for repeated clinical use and reprocessing. The blade incorporates fiber‑optic illumination components routed to the distal region for consistent light delivery during laryngoscopy. The spare‑insert form allows replacement of the blade element while retaining the handle and light source assembly, reducing replacement cost and downtime.

Quality & Compliance

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