As shown in fig. 7, the emergency rescue device comprises an air bag structure 1 and an inflation device, wherein the inflation device comprises a sealing cover 3 and a host; the gasbag structure 1 is provided with a matching port 2 for the host machine to penetrate into the inner cavity of the gasbag structure 1, the sealing cover 3 is in threaded connection with the matching port 2, and the inner side of the sealing cover 3 is provided with a sealing gasket 4. The air bag structure 1 is a high-altitude falling lifesaving mat, and the number of the air charging devices is two; when the high-altitude falling lifesaving pad is in a filling state, the two inflation devices are respectively positioned at the left side and the right side of the high-altitude falling lifesaving pad.

In addition, the structure of the inflator in this embodiment is the same as that of the inflator in embodiment 1, and the size of the inflator, the inflation speed of the inflator 8, and the content of the sodium azide 20 are adjusted according to actual circumstances.

The air bag structure 1 of the utility model can be a life buoy, a rubber dinghy and a high-altitude falling life cushion, and can be made into other shapes according to the needs to meet various requirements of rescue work; therefore, the utility model has the advantage of the wide range of application.

The utility model discloses an aerating device has that pump 8 aerifys and sodium azide 20 decomposes and aerifys two kinds of modes of aerifing, can effectively improve gasbag structure 1's the gas velocity for operating personnel can lose heart with gasbag structure 1 and deposit, and realize quick inflation when getting to use, ensures that the rescue personnel in time develoies rescue work, overcomes current gasbag structure 1 and exists to aerify and deposit and account for the space, lose heart and deposit the long defect of inflation time.

The above description is for the detailed description of the preferred possible embodiments of the present invention, but the embodiments are not intended to limit the scope of the present invention, and all equivalent changes or modifications accomplished under the technical spirit suggested by the present invention should fall within the scope of the present invention.
