摘要：
A laryngoscope blade for use in viewing the vocal cords of a patient in performance of an endotracheal intubation includes a laryngoscope blade portion connectable to a laryngoscope handle to lift the patient's tongue and mandible for viewing the vocal cords and aid in the insertion of an endotracheal tube, the blade portion includes a proximal portion and a distal portion； a white light source carried by the blade portion； a black light source carried by the blade portion to prompt the visible effects of fluorescence and phosphorescence with respect to the patient's vocal cords for viewing the vocal cords and passing of the endotracheal tube there between during endotracheal intubation, the black light source located closer to the distal portion and the white light located to the proximal portion, and the black light source emitting electromagnetic radiation having a wavelength in the range of 300 to 450 nm.
