[0038] The air pressure sensing unit 1, comprising a flexible air bag 100 filled with gas, and a gas hole 101 penetrating the top and bottom surface of the flexible air bag 100; the gas hole 101 is used for skin surface ventilation; ​

[0039] The pressure display unit 2 comprises a pressure conversion assembly 210 for converting the internal pressure of the flexible air bag 100 into mechanical energy, and an internal pressure display assembly 220 for further converting the mechanical energy generated by the pressure conversion assembly 210 into a pressure value for display.

[0040] In the embodiment of the present application, the pressure sensing is realized by using the air pressure sensing unit as a whole, the pressure is converted into mechanical energy by means of the pressure display unit, the corresponding pressure value is output, and then the pressure value is quantitatively displayed, and the control and adjustment of the pressure can be realized by means of the internal pressure control unit 3. In use, the device cover is attached or wound to the corresponding part, and then fixed to the skin surface by means of the bandage. After the bandage is wrapped, the internal pressure will squeeze the gas in the flexible air bag 100 to the surrounding, so as to convert the gas pressure in the flexible air bag 100 into mechanical movement under the action of the pressure conversion assembly 210, so as to realize the reverse conversion of the pressure value according to the movement amount, and finally realize the visual output by the internal pressure display assembly 220, and complete the visual display of the internal pressure of the bandage wrapping.
