The positioning device can record the action track and the position of the mask wearer, and can be a positioning chip. The isolation mask is provided with a power supply system of a self-contained power supply, and if a storage battery is arranged, the isolation mask can provide necessary electric support for a required sensor, an air inlet supercharging device or an air exhaust decompression device.

In one embodiment, a sensor for measuring at least one of body temperature, blood pressure, heart rate, blood oxygen saturation, and respiratory rate is attached to the elastic sealing member 4. The sensor passes through elastic sealing element 4 and the facial laminating of wearer, guarantees the signal acquisition accuracy.

Of course, the sensor is not limited to be provided on the elastic sealing member 4, and may be provided on the mask body 1, the air intake structure 2, or the air exhaust structure 3.

In the isolation mask of the above embodiment, the isolation mask further comprises an indicating device, the indicating device displays information in at least one mode of sound, illumination and characters, and the indicating device is arranged on the mask body 1, the air inlet structure 2 or the air outlet structure 3 and used for indicating the vital signs of a wearer. Wherein, indicating device can be pilot lamp, display screen, sound alarm etc. if there is the unusual person of suggestion wearing fast. The indicating device is connected with the controller or wirelessly connected with the cloud end, and information of the controller or the cloud end is displayed through the indicating device.
