ABSTRACT:
An improved laryngoscope blade for use with a conventional laryngoscope handle and conventional means for illumination. The improvements to the blade include a small reverse curve at the tip of the blade to better visualize the depth of insertion of the blade, include a greater width of the portion of the blade proximal to the handle to provide improved means for controlling the tongue, and include a more gradual curvature 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 which may be thickened to serve as a bite block, and raised areas to define grooves on the surface of the blade for insertion of an endotracheal tube and/or a suction catheter.
