Abstract

The present invention provides an improved visual laryngeal mask comprising a snorkel, an end of the snorkel is provided with a fixing seat. The fixing seat is provided with an airbag, and the fixing seat has a recess which is provided with an airway opening. The inner wall of the snorkel longitudinally extends an imaging cavity and a cleaning channel. The imaging cavity has a built-in imaging device, and the imaging cavity and the cleaning channel protrude forward relative to the airway opening to form a stopper which prevents an epiglottis from blocking the imaging device.
