Embodiment 1
[0043] Such as figure 1 As described above, it is a functional block diagram of a manometry device for an artificial airway air bag with a constant pressure function according to an optional embodiment of the present invention. The manometry device includes a control system 10, an air bag 20 and an output system 30;
[0044]The control system 10 is used to control the pressure value of the airbag 20 to drive the pressure of the airbag 20 to 25-30cmH 2 O standard pressure range;
[0045] The control system 10 includes a pressure sensor 11, an AD chip 12, a control unit 13, a time calculation unit 14, and a delay unit 15;
[0046] The air bag 20 is inserted into the patient's trachea and the air bag 20 is connected to the outside control system 10 through a pipeline. A pressure sensor 11 is arranged in the pipeline connecting the air bag 20 to the control system 10. The pressure sensor 11 detects the pressure in the air bag 20 in real time. pressure; the pipeline between the a...
Embodiment 2
[0058] Such as figure 2 Shown, it is the using method of the artificial airway airbag manometry device with constant pressure function of a preferred embodiment of the present invention, above-mentioned using method is on the basis of using above-mentioned device, concrete steps are as follows:
[0059] S1, the pressure sensor 11 detects the pressure of the airbag 20 in real time, and sends the detection value to the described control unit 13 with the AD chip 12;
[0060] S2, the control unit 13 receives the detection value detected by the pressure sensor 11 in real time, and compares the received detection value with the pressure range of the device preset air bag to show the state of the air bag 20; if the comparison result shows that the detection value is located at 25-30cmH 2 O between the standard pressure ranges, then the device works normally, and the pressure sensor 11 continues to detect the pressure of the air bag 20; if the comparison result shows that the detecti...
experiment example
[0065] Such as image 3 As shown, a certain patient is adopted in this experimental example, and the above-mentioned pressure measuring device is used for pressure measurement. The patient coughs repeatedly during the operation, and the repeated cough causes the pressure value of the airbag 20 to change, exceeding 30cmH 2 O standard pressure, but its duration is less than 20 seconds, and control unit 13 controls electromagnetic valve 17 and does not work, and its pressure is positioned at 25-30cmH after air bag 20 pressure is steady 2 O standard pressure range
