Laryngeal mask

The invention discloses a laryngeal mask. The laryngeal mask comprises a pipe body and a mask body, wherein the pipe body is provided with a pipe connecting end; the pipe body is provided with a breathing cavity channel for breathing gas to circulate; the mask body is provided with a mask connecting end; the mask connecting end is in sealed connection with the pipe connecting end; the mask body isprovided with a breathing cavity communicating with the breathing cavity channel and a breathing opening for the breathing cavity to be communicating with a breathing channel; an air bag for being insealed abutting connection with the respiratory tract opening of a patient is annularly arranged on the periphery of the breathing opening; a guiding assembly is arranged on the air bag; and when theair bag extracts air, the guiding assembly guides the air bag to shrink according to the outline of the air bag in the inflated state. According to the technical scheme, the problem that the air bagdeforms after air extraction, and therefore laryngeal mask implantation is affected can be solved.
