ABSTRACT:
The present invention is a self-retaining laryngoscope composed of a palate brace or blade, a slider, and a tongue blade. The angulated tongue blade puts less force on the blade, reduces trauma, and is not conducive for mechanical failure. The slider interacts with the tongue blade by widening the opening of the mouth, and acts as a bite block. The fenestrated palate blade provides an unobstructed view of the vocal cords during intubation, and allows removal of the laryngoscope over the endotracheal tube without displacing it. The result is a laryngoscope that requires only one hand to use properly, and has superior retraction due to its shape.
