The control module can be a micro-control system comprising a single chip microcomputer, and the single chip microcomputer can be a commercially available C8051F350 single chip microcomputer. The power supply module comprises a power switch and a power supply for supplying power to each module. The interface of the gas flow sensor is connected with the corresponding interface in the control module, and a driving program, a data receiving, processing and outputting program and the like are written in the control module in advance. After the power supply module starts to supply power, the gas flow sensor transmits a tidal volume signal measured in real time to the control module, the control module immediately sends a signal to the electronic display screen connected with the control module, the real-time tidal volume is displayed on the electronic display screen, and an operator can adjust the frequency or the force of pressing the air bag in time after directly reading the signal, so that the tidal volume conveyed into the body of a patient is changed. In the scheme, the electronic display screen can be an OLED display screen or an LCD display screen; the main body can be a plastic shell, and the installation connecting pipe can be a pipeline structure communicated with the mask and the air outlet pipe.
Preferably, the tidal volume detection device includes a base portion and a rotation portion rotatably connected to the base portion; the base part is connected with the installation connecting pipe, and the rotating part is connected with the main body.
Therefore, in actual use, due to the fact that the breathing air bags are different in placement positions, the medical staff can possibly have observation blind areas in actual operation, and cannot observe the electronic display screen. Thus, the electronic display screen is made rotatable. In the scheme, the base part is rotationally connected with the rotating part to drive the electronic display screen to rotate. The base part and the rotating part can be connected through a rotating shaft or can be connected through a bearing.
Preferably, the rotating part includes a turntable, the base part includes a packaging housing for packaging a part of the turntable therein, the packaging housing is provided with a limiting groove for preventing the turntable from moving up and down, and the turntable is clamped in the limiting groove.

Therefore, the moisture content detection device is provided with the voice alarm module, and in the scheme, the voice alarm module can be a buzzer. The voice alarm module is in communication connection with the control module. The program is written in the control module, the range of the tidal volume is set, and the maximum value is generally not more than 1200 ml.

Therefore, the voice alarm module 29 is arranged in the tidal volume detection device 2, and the voice alarm module 29 is a buzzer. The voice alarm module 29 is in communication connection with the control module 23. The control module 23 is programmed to set a tidal volume range, the maximum value of which is generally no more than 1200 ml.
