Portable video laryngoscope

Claim 1

A laryngoscope for aiding in the examination of a patient by an observer relying entirely upon machine generated data to derive medical conclusions, comprising: a probe and a handle, said probe having a proximal end connected to said handle and an articulating, adjustable distal end projecting therefrom, said handle including a distal end connected to said proximal end of said end probe, the distal end of the probe including generally ovoid, C-shaped gripping means, the gripping means including a pair of elongated grasping lips and an internal clamping assembly for controlling the gripping means; information gathering means including digital camera means mounted to said distal end of said probe to generate digital machine data and display means adjustably and releaseably mounted on said proximal end of said handle and operationally connected to said digital camera means whereby a 2-D visual display is provided a human observer, said display means defining a first working position to permit line of sight insertion of said probe into the throat cavity of a patient and a second working position in which said line of sight is blocked, so said observer relies entirely upon machine generated data for to derive medical conclusions.

Claim 8

A method of intubating the trachea of a patient by an intubator using an incubating instrument and a laryngoscope, the method comprising steps as follows: providing the laryngoscope with a handle and a probe, the probe having a proximal end connected to the handle and a distal end projecting laterally therefrom; inserting the probe into the patient's mouth while grasping the laryngoscope by the handle using a first hand of the intubator for steady and constant lifting and moving to one side the patient's tongue, with the second hand of the user manipulating the flexion control wheel to acquire visual capture of the patient's tracheal opening and other oral internal structures to view; providing illuminating means for illuminating the trachea opening and other oral internal structures; providing controls to manipulate the articulating end of the probe to secure an adequate view of the operating field; providing an oxygen delivery means to the distal end of the probe; providing camera means mounted on a blade of the laryngoscope 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; introducing oxygen gas to the area of the trachea through the oxygen delivery means; inserting the intubating instrument into the mouth of a patient using the controllable grasping means to guide and release the ET tube, while a second hand of the intubator pushes in the intubating instrument for insertion of an endotracheal tube into the patient's tracheal opening; and positioning the display means on the handle so that while the intubator inserts and manipulates the intubating instrument into the patient's trachea the 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.

Claim 9

A method of intubating the trachea of a patient by an intubator using an incubating instrument and a laryngoscope, the method comprising steps as follows: providing the laryngoscope with a handle and a probe, the probe having a proximal end connected to the handle and a distal end projecting laterally therefrom; inserting the probe into the patient's mouth while grasping the laryngoscope by the handle using a first hand of the intubator for steady and constant lifting and moving to one side the patient's tongue, with the second hand of the user manipulating the flexion control wheel to acquire visual capture of the patient's tracheal opening and other oral internal structures to view; providing illuminating means for illuminating the trachea opening and other oral internal structures; providing controls to manipulate the articulating end of the probe to secure an adequate view of the operating field; providing an oxygen delivery means to the distal end of the probe; providing camera means mounted on a blade of the laryngoscope 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; introducing oxygen gas to the area of the trachea through the oxygen delivery means; inserting the intubating instrument into the mouth of a patient using the controllable grasping means to guide and release the ET tube, while a second hand of the intubator pushes in the intubating instrument for insertion of an endotracheal tube into the patient's tracheal opening; and positioning the display means on the handle so that while the intubator inserts and manipulates the intubating instrument into the patient's trachea the 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.
