ABSTRACT:
An improvement for laryngoscope blades is disclosed, for expanding the field of view beyond that directly visible to a person performing intubation. A small endoscope is provided, slidably attached to the blade, and includes an eyepiece near the laryngoscope handle and a front lens near the blade tip. The endoscope is adapted to expose for remote viewing through the eyepiece an additional field of view generally above and beyond the blade tip. The endoscope is slidably attached to the blade so that the endoscope can be advanced and retracted when and as required to assist intubation. The blade includes an upper protrusion extending outwardly from the blade spoon, and a ridge depending downwardly from the protrusion for shielding the front lens of the endoscope from tissue surrounding the lens.
