A laryngeal mask airway includes an airbag cover (1) and an extension body (2). The extension body (2) is shaped according to the natural curvature of the oral cavity and the throat airway and is arc-shaped, and has a proximal end for penetrating into the oral throat and a distal end located outside the oral cavity. The extension body (2) has an airway tube cavity (3) extending from the distal end to the proximal end, thereby forming a distal vent (31) and a proximal vent (32) respectively. The cover belly (11) of the airbag cover (1) with a concave space is communicated with the proximal vent (32) of the airway tube cavity (3). The novel laryngeal mask airway further includes a video tube cavity (6), and the video tube cavity (6) extends from the distal end to the proximal end in the extension body (2), thereby forming a distal end opening of video tube cavity (62) at the distal end and a blind end transparent window (61) at the proximal end. The blind end transparent window (61) is located at one side of the proximal vent (32) of the extension body. The laryngeal mask airway integrates the functions of visual monitoring, airway breathing, esophageal drainage, throat drainage and intubation through laryngeal mask, which can improve the management of visual airway monitoring and avoid airway damage during blind intubation.
