Abstract

Abstract A fiber optic intubating scope with camera and screen is used in the intubation of an endotracheal tube in patients whose larynges are not easily viewed with a laryngoscope because of morphological irregularities or complications. Use of the invention in intubation of such patients in emergency situations facilitates exact placement of the endotrachael tube by providing a screen-displayed image of the patient's pharynx and larynx, and further allows the physician to simultaneously monitor the internal placement of the endotrachael tube and the external conditions of the patient. The intubation process, facilitated by use of the invention, can be accomplished via the pharynx of nasopharynx. In alternative embodiments, the invention can be powered from a peripheral source or can be powered by means of a self-contained power source pack. The invention has both emergency and non-emergency intubation application, as well as utility in the form of a bronchoscope.
