An electrically-powered visual display unit (VDU), commonly known as a screen or a monitor, designed to be used exclusively in conjunction with a flexible video endoscope to display to the operator the graphical information captured by the endoscope to facilitate its manipulation during the endoscopic procedure; typically difficult and non-difficult intubation procedures to maintain an open airway. It is typically a portable device with a liquid crystal display (LCD) colour screen and a direct electronic signal connection to the endoscope.
