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.

Claims

1. An intubating scope comprising in combination:

a housing adapted to be hand-held;

screen means contained in said housing;

camera means contained in said housing for transmitting light images to said screen;

semi-malleable hollow tube means connected at one end thereof to said housing;

at least one fiber optic tube disposed within said malleable tube means, said fiber optic tube connected at one end thereof to said camera means for providing light images from the opposite end of said fiber optic tube to said camera means; and

a power source connected to said camera and fiber optic tube.

2. A scope as set forth in claim 1, wherein a bundle of fiber optic tubes are contained in said semi-malleable tube and are attached to said camera means.

3. A scope as set forth in claim 1, wherein said semi-malleable hollow tube is an endoctracheal tube for intubating an individual'"'"'s throat.

4. A scope as set forth in claim 1, wherein said power source is contained in said housing.

5. A scope as set forth in claim 1, wherein said power source is disposed outside said housing and is connected to said camera and fiber optic tube.

6. A scope as set forth in claim 1, wherein the end of the fiber optic tube opposite the end connected to said camera extends beyond the end of the semi-malleable tube and can be manipulated by lever means connected to said housing.

7. A scope as set forth in claim 1, wherein said camera means comprises a cathode ray tube type camera.

8. A scope as set forth in claim 1, wherein said camera means comprises an electron scanning type camera.
