Macintosh Laryngoscope blade F/O, Int/T 150mm, #5

Clinical Application

Macintosh curved blades are the standard geometry for routine direct laryngoscopy to expose the glottic opening and facilitate placement of an endotracheal tube. The #5, 150 mm length is sized for larger adult patients where additional blade length is required to reach the vallecula and lift the epiglottis indirectly. Integrated fiber-optic illumination provides consistent, shadow-free light at the tip to improve visualization during induction, rapid sequence intubation, and other airway management procedures.

Design & Configuration

The Macintosh curve is designed to be positioned in the vallecula so the epiglottis is elevated indirectly when the blade is lifted, creating a line of sight to the vocal cords while minimizing soft-tissue compression. The size #5 length offers extended reach for adult anatomy. Fiber-optic integration routes light to the distal blade surface, improving mucosal illumination without reliance on a filament bulb at the tip. The blade interfaces with a compatible fiber-optic laryngoscope handle for power and secure attachment.

Instrument Specifications

• Pattern: Macintosh curved blade
• Size: #5
• Length: 150 mm
• Illumination: Fiber-optic (integrated light channel)
• Intended use: Direct laryngoscopy and endotracheal intubation for adult patients
• Construction: Reusable surgical-grade blade

Material & Construction

Constructed from surgical-grade stainless steel for strength, corrosion resistance, and reprocessability. The blade incorporates an integrated fiber-optic light channel to deliver distal illumination; fiber-optic components are fixed into the blade body to provide consistent light transmission when connected to a compatible light source. The design supports repeated cleaning, decontamination, and sterilization according to facility protocols.

Quality & Compliance

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

Brand Comparison

Comparable in form and function to equivalent instruments offered by major US medical suppliers.
