[0011] The outer end of the subglottic suction tube body is fixedly connected to the subglottic suction tube head.

[0012] The outer end of the airbag inflation connecting tube is fixedly connected to the airbag inflation connecting tube head.

[0013] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:
