Abstract
A laryngoscope, for use in intubating a patient'"'"'s trachea, especially in emergency situations. The laryngoscope has a camera mounted in the vicinity of a distal end of its blade to observe the patient'"'"'s trachea opening and other oral internal structures in a visual field. The camera is connected, typically via a fiberoptic cable, to a lightweight portable television screen, preferably mounted on the laryngoscope handle, for displaying the visual field to the a Professional Intubator so as to enable him or her to observe continuously the trachea opening and other oral internal structures as he or she manipulates the intubating instrument. The laryngoscope with the camera and screen thereon preferably is held in one of the Professional Intubator'"'"'s hands to lift and move aside the patient'"'"'s tongue steadily and constantly. The other hand of the Professional Intubator then is free to manipulate the intubating instrument. Mounting the camera and the screen on the laryngoscope, which remains quite steady, provides the Professional Intubator with a continuous steady display of the trachea opening and other oral internal structures on the screen while the intubator also sees directly down the patient'"'"'s mouth.

15. A laryngoscope for use with an intubating instrument in a procedure for intubating a trachea of a patient, the laryngoscope comprising:
-
a handle for a Professional Intubator to grasp in a first hand, a blade with a proximal end connected to the handle and a distal end extending laterally therefrom for insertion into a patient'"'"'s mouth during the procedure to elevate and move to one side the patient'"'"'s tongue steadily and constantly; camera means mounted on the blade in the vicinity of the distal end of the blade for observing a visual field that includes the patient'"'"'s trachea opening and other oral internal structures; the camera means connected operatively to a portable lightweight display means arranged for the Professional Intubator to see the field of view on the display means, whereby the Professional Intubator'"'"'s second hand is available to manipulate the intubating instrument without disturbing the camera means.

16. A method of intubating a trachea of a patient by an Professional Intubator using an intubating instrument and a laryngoscope, the method comprising steps as follows:
-
providing the laryngoscope with a handle and a blade, the blade having a proximal end connected to the handle and a distal end projecting laterally therefrom; inserting the blade into the patient'"'"'s mouth while grasping the laryngoscope by the handle using a first hand of the Professional Intubator for steadily and constantly lifting and move to one side the patient'"'"'s tongue and exposing the patient'"'"'s trachea opening and other oral internal structures to view; providing illuminating means for illuminating the trachea opening and other oral internal structures; providing camera means mounted on the blade in the vicinity of the distal end of the blade so that it observes a field of view that includes the patient'"'"'s trachea opening and other oral internal structures; having the camera means operatively connected to display means for viewing the field of view thereon; inserting the intubating instrument into the mouth of a patient using a second hand of the Professional Intubator and manipulating the intubating instrument for insertion of a tube into the patient'"'"'s trachea opening; positioning the display means on the handle so that while the Professional Intubator inserts and manipulates the intubating instrument into the patient'"'"'s trachea the Professional Intubator observes the trachea opening and other oral internal structures of the patient on the display means unaffected by the manipulating of the intubating instrument.
