Reduced Flange Improved View (RFIV)
Macintosh Standard Blades
Patented modification to the "English" profile laryngoscope blade. Reduction in the flange will enable the user to exert less force upon the maxillary incisors. A channel has been created which adds strength to the blade as well as increases the viewing area. This provides a channel through which an endotracheal tube may be inserted after visualizing the cords. The reduced flange protects teeth during intubations. • US patent no. D413977
