The throat mask comprises a breath tube having an end portion which is expanded as a throat sheet with a shape like a water drop; a resisting sheet enclosing the throat sheet; a front end of the resisting ring being extended with a guide unit which is a deformable semi-elliptical soft tube with two ends; the two ends of the soft tube being connected to the resisting ring; an airbag enclosing a periphery of the resisting ring so as to avoid the resisting ring and the guide sheet to contact the throat directly. The soft tube has a soft structure deformable to fit the space receiving the guide unit. After the guide unit passes into the throat, the soft tube can collapse downwards or swings at two sides so as to make the throat feel easy and the guide unit will not hinder the throat. |
