Abstract:
A video laryngoscope has a handle and a groove on one side of the handle. The groove is used for guiding a guide wire when the larynogoscope is placed in a patient's mouth. A video camera located near the end of the handle is used to view the area around the glottis. When the guide wire is properly positioned near the glottis, the upper part of the guide wire is disengaged from the groove so as to allow an endotracheal tube to be slipped over the guide wire and to be inserted into part of the trachea through the glottis. When the tube is properly inserted for intubation, the guide wire is removed from the tube. An illuminating light source such as an LED lamp can be installed at the end of the handle to provide illumination for the video camera.
