Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, there will now be described in detail, with reference to the accompanying drawings, a non-limiting detailed description of the present invention.

As shown in fig. 1 to 3, the tracheal fixing device of the present embodiment comprises a nasal mask 1, an annular air bag 2 and tethers 3 disposed at both sides of the annular air bag 2, wherein the annular air bag 2 is disposed around the periphery of the nasal mask 1 and fixedly connected thereto; the nose mask 1 is provided with a vent pipe 6 relative to the position of the nostril, the vent pipe 6 is communicated with the inside of the nose mask 1, the air pipe is inserted into the nostril through the vent pipe 6, and a locking device 5 for fastening the air pipe is arranged between the air pipe and the vent pipe 6. The nose mask 1 is tapered. The annular air bag 2 is provided with an inflating device 7, and the inflating device 7 is detachably connected with the annular air bag 2. The inflation device 7 comprises an inflation ball 71 for inflating the annular air bag 2, an air duct 73 for connecting the annular air bag 2 and the inflation ball 71, and a deflation valve 72 arranged on the air duct 73 or the annular air bag 2, wherein the connecting end of the air duct 73 is communicated with the annular air bag 2.
