BIZZARRI-GIUFFRIDA
FLANGE-LESS MAC
A modification of the MacIntosh blade with the upper flange removed. This blade is especially well suited for use in patients with a limited mouth opening, prominent incisors, receding mandible, short thick neck or having the larynx in an extreme anterior anatomical position. The absence of the flange greatly reduces the chance of trauma during laryngoscopy.

BLECHMAN
This modification of the MacIntosh style blade is designed with the tip angled to further elevate the epiglottis in a patient of short spine and sweep the tongue to the left with the ability to tip the blade upward, with the handle between the teeth, while viewing from the right side. The viewing is further enhanced due to the modification of the flange by removal of the flange near the lock of the blade.
