Laryngeal mask airway

Provided is a laryngeal mask airway, comprising a laryngeal mask airway main body (10) and a view device (20). The laryngeal mask airway main body (10) comprises a catheter (12), and a sealing base (13) connected to the distal end of the catheter (12), and the view device (20) comprises a control part (22) and a vidicon (23), wherein an image sensor (231) is formed at the distal end of the vidicon (23), and an air guide channel (101) and a view lumen (103) are formed in the laryngeal mask airway main body (10); and a first blind end part (103a) that is closed by a light-transmitting material is formed at the distal end of the view lumen (103), the vidicon (23) is inserted into the view lumen (103) in a pluggable manner, the distal end of the view lumen (103) and the distal end of the vidicon (23) extend into the sealing base (13), and the distal end of the vidicon (23) can be bent and reset. The vidicon (23) is sealed inside the view lumen (103) and does not come into contact with internal tissue of a patient during use, such that the vidicon (23) can be reused in a relatively safe manner; and the distal end of the vidicon (23) can bypass the epiglottis, and the drooping epiglottis can be pushed aside by means of controlling the distal end of the vidicon (23) to be bent upwards so as to obtain a good view.
