The blade includes a handle connecting backend segment containing a light source and an elongated tongue lifting and tube guiding front segment which carries a light guide. This latter segment is made up of first and second subsegments extending its entire length, the first subsegment being disposed within a plane through the elongation axis of the hand gripping segment and serving to contain a light guide and the second subsegment being disposed laterally to one side of the same plane and serving to elevate the patient's tongue and to guide an endotracheal tube into the patient's throat.
