emitting the mixed light from the fiber optics of the fiber optic laryngoscope blade.

5. The method of claim 4 , further including performing direct laryngoscopy, comprising:

using the laryngoscope to lift a patient's tongue and mandible for at least one of locating and viewing a foreign object in the patient;

emitting the mixed light from the fiber optics to prompt a visible illumination effect in the patient's epiglottis and vocal cords resulting from absorption of some or all of the ultraviolet light by tissues in the patient, providing a back light from phosphorus reactions, and allowing a reaction with a foreign body in the patient; and

locating the foreign object in the patient.

6. The method of claim 4 , further including performing direct laryngoscopy, comprising:

using the laryngoscope to lift a patient's tongue and mandible for viewing the vocal cords adjacent the larynx and to aid in the insertion of an endotracheal tube past the vocal cords;

emitting the mixed light from the fiber optics to prompt a visible illumination effect in the patient's epiglottis and vocal cords resulting from absorption of some or all of the ultraviolet light by tissues in the patient, providing back light from phosphorus reaction, and making the patient's vocal cords at the glottis visible and identifying a pathway for the endotracheal tube to the trachea; and

performing endotracheal intubation in the patient by inserting the endotracheal tube into the patient's mouth, between the patient's visible vocal cords into the larynx, and then into the trachea.

7. A method of using a laryngoscope, comprising:

providing a laryngoscope comprising a laryngoscope handle and a fiber optic laryngoscope blade including fiber optics, the laryngoscope handle including one or more power sources, a light source assembly carried by the handle body and powered by the one or more power sources, a connection section for mechanically connecting the fiber optic laryngoscope blade to the laryngoscope handle and optically coupling the light source assembly in the laryngoscope handle to the fiber optics of the fiber optic laryngoscope blade, wherein the light source assembly is spaced proximal of the connection section and the light source assembly includes a mirrored light mixing chamber;

mechanically and optically coupling the fiber optic laryngoscope blade and fiber optics to the connection section of the laryngoscope handle to form a laryngoscope;

actuating the light source assembly;

transmitting mixed light including UV light from the light source assembly through the fiber optics of the fiber optic laryngoscope blade;

emitting the mixed light from the fiber optics of the fiber optic laryngoscope blade.

8. The method of claim 7 , further including performing direct laryngoscopy, comprising:

using the laryngoscope to lift a patient's tongue and mandible for at least one of locating and viewing a foreign object in the patient;

emitting the mixed light from the fiber optics to prompt a visible illumination effect in the patient's epiglottis and vocal cords resulting from absorption of some or all of the ultraviolet light by tissues in the patient, providing a back light from phosphorus reactions, and allowing a reaction with a foreign body in the patient; and

locating the foreign object in the patient.

9. The method of claim 8 , wherein the mixed light is a mixture of white light and UV light.
