<p>This invention is a laryngoscope blade (10) for use with a conventional laryngoscope handle (12), and conventional means (14) for illumination. The improvements to the blade (10) include a small reverse curve at the tip (32) of the blade to better visualize the depth of insertion of the blade; include a greater width of the portion of the blade proximal (22a) to the handle to provide improved means for controlling the tongue; and include a more gradual curvature (20) of the blade to better conform to the shape of the airway opening when the patient is properly positioned for laryngoscopy. The blade may also include a vertical wall (50) which may be thickened to serve as a bite block; raised areas (40) to define grooves on the surface (26) of the blade for insertion of an endotracheal tube, and/or a suction catheter.</p> |
