Patent ID: 6843769

Claim:
An optical-light emitting laryngoscope for naso-tracheal and/or oral-tracheal intubation and/or for visualizing the opening of the trachea, of the type comprising: a hollow, tubular main body having proximal end and a distal end such that proceeding from the proximal end is a first section that is straight and which continues to a second section that is anatomically curved in a shape for insertion into the inside of the mouth and the access zone of the larynx and terminating at the distal end which has angled walls; and a light source positioned at the distal end of the main body, wherein said main body provides an uninterrupted internal pathway for introduction of a device from the proximal end to the distal end thereof and wherein the main body includes a separate visualization duct positioned within the main body which extends from the proximal end to the distal end of the main body, the visualization duct comprising: an eyepiece lens located at the proximal end of the visualization duct; and a first and a second planar reflecting elements positioned in spaced apart relationship on an interior surface along the anatomically curved section of the visualization duct to enable viewing of reflected light and images through the proximal end during insertion of the laryngoscope and during insertion of any device into the trachea through the uninterrupted internal pathway.
