  • Patent number: 4827910
    Abstract: Whereas the mouth, pharynx and larynx can be inspected by direct vision or by indirect mirror vision, the most widely used instrument for personal endoscopy is the laryngoscope. Through the years many modifications have been made to improve laryngoscopes. But in considering laryngoscope improvements it should be understood that frequently the instrument is employed in emergency situations where the length of time taken to insert the laryngeal blade is critical. Improvements which demand careful manipulation, and thereby result in loss of valuable seconds, are not the most desirable. By this invention a laryngoscope blade which comprises upwardly extending appendages at either side of the tip of the blade and a jog between the appendages such that a fork-like guide is formed is provided which can be more rapidly introduced. This construction facilitates moving the epiglottis forwardly, and provides a better view of the trachea. It also shortens endotracheal intubation time.
