Curved design allows the tip to be guided to the epiglottic vallecula for direct visualization of the glottis while maintaining the tongue to the side for intubation.
Straight design with a shallow curve tip provides greater control in patients whose epiglottis is larger, as in pediatrics. Infant and neonatal Miller blades are also available with a delivery port to provide supplementary oxygen during laryngoscopy.
Based on the standard Macintosh blade, the Flexible blade has a hinged tip operated by a lever mechanism. This elevates the epiglottis while reducing the amount of force required. A Flexible blade has been shown to improve the view during difficult intubations and in patients wearing cervical collars.
American Mac Blade
Gentle curve design allows for easy access to the vallecula, indirectly lifting the epiglottis for direct visualization of glottis.
Integrates the straight Jackson blade with the curved distal tip Miller, providing greater visibility and an almost direct line approach to the trachea during difficult intubations.
Flat length of the blade improves the ability to lift and hold the tongue out of view and is commonly used during pediatric and neonatal intubations.
For neonatal and infant use, the blade offers an improved view compared to the Conventional Miller, providing greater control of the epiglottis with a subtly wider distal end.
For neonatal and infant use, Robertshaw blades feature a gentle shallow blade curvature to lift the epiglottis indirectly in a similar way to Macintosh Blades.
Originally an infant blade for asphyxia neonatorum, also used for pediatric patients.
