[0046] The airbag 20 is inserted into the trachea inside the patient and the airbag 20 is connected to the outside of the control system 10, and the pressure sensor 11 pressure sensor 11 is provided in the conduit of the airbag 20 connection control system 10 in real time to detect the airbag 20 Pressure; the air pump 16 is also connected to the conduit between the control system 10 connected to the outside, and the air pump 16 is driven to the airbag 20 to drive the airbag 20, the airbag 20 is connected to the outside of the control system 10 The pipelines in Shanghai are provided with solenoid valve 17. The solenoid valve 17 is opened to the airbag 20 to achieve the pressure of the airbag 20 to reach the pressure of 25-30cmH. 2 O Standard pressure range;

[0047] The AD chip 12 receives the pressure sensor 11 in real time to detect the pressure value and transmit the detected value to the control unit 13;

[0048] The control unit 13 receives the pressure value detected by the pressure sensor 11 in real time and compare the received detection value to the preset value to display the state of the airbag 20;

[0049] The time calculation unit 14 is configured to calculate the detection value of the detection value after comparison completion of the control unit 13 is not within the preset value duration T;

[0050] When the duration T is less than 20 seconds, the launch unit 15 operates, the delay unit 15 feeds back the signal to the control unit 13, and the control unit 13 controls the pressure sensor 11 to continuously detect the pressure value of the airbag 20;

[0051] When the duration T is greater than 20 seconds, the time calculation unit 14 feeds back the signal to the control unit 13, and the control unit 13 displays the detected detected value detected by the received pressure sensor 11;

[0052] The detected value is less than 25cmh 2 O When the standard pressure is standard, the control unit 13 controls the air pump 16 to operate, the air pump 16 is inflated, and when the pressure sensor 11 detects the pressure value of the airbag 20 located at 25-30cmH 2 O When the standard pressure range is between, the control unit 13 controls the air pump 16 to stop operation;

[0053] The detected value is greater than 30cmh 2 O When the standard pressure is standard, the control unit 13 controls the solenoid valve 17 to open, and the solenoid valve 17 is opened, and the airbag 20 is lowered, and the pressure of the airbag 20 is lowered, and the pressure sensor 11 detects the pressure value of the airbag 20 located at 25-30cmH 2 O When the standard pressure range is between, the control unit 13 stops the solenoid valve 17;

[0054] In this embodiment, the preset value interval is 25-30cmh 2 Of;

[0055] In this embodiment, the airbag pressure sensing device is provided with a delay unit 15, and when the airbag is generated when the patient is coughing, the time calculation unit 14 calculates the duration of the pressure change, and when the time is less than 20 At second, the air pump 16 and the solenoid valve 17 do not work, do not inflate or give up the airbag, ensure that the airbag 20 is stable after 25-30cmH 2 O Between the standard pressure range; when the time is more than 20 seconds, the control unit 13 performs an inflatable or air-proof treatment according to its actual detection value, and adjusts the pressure of the airbag 20 at 25-30cmH. 2 O Between the standard pressure range.

[0056] In this embodiment, the apparatus also includes an output system, and the output system can be one or several of a printer with a memory function or a computer with a storage function.
