Video laryngoscope

Patent Pending The conventional direct laryngoscope uses a line of sight provided by a rigid viewing instrument with a light on the blade or intra-oral portion which requires a direct view of the target larynx; this view is clearly seen in 80-90% of attempts. The frequent failure of direct laryngoscopy to provide an adequate view for tracheal intubation led to the development of alternative devices such as the lighted stylet, and a number of indirect fiberoptic viewing laryngoscopes, such as the fiberscope, Bullard scope, Upsher scope, and the WuScope.
