In this embodiment, the other end of the first conduit 61 extends above the liquid level in the liquid bottle 2. The liquid outlet pipe is connected with a first one-way valve 93, liquid can only flow into the second pipeline 62 from the liquid bottle 2 through the liquid delivery pipe 51, the air outlet pipe is connected with a second one-way valve 94, and air can only flow into the second pipeline 62 from the outlet of the normally closed valve, so that liquid reflux can be prevented.
A pressure sensor 91 and/or a flow meter 92 is connected to the second pipe 62 and the liquid feeding pipe 51. Taking the second pipeline 62 connected with a pressure sensor 91 and the liquid feeding pipe 51 connected with a flowmeter 92 as an example, the pressure sensor 91 can detect the pressure in the human body cavity in real time, and the flowmeter 92 can calculate the real-time flow rate and the total liquid amount of the liquid fed into the human body cavity; when the pressure of the liquid or the total amount of the accumulated transport liquid exceeds the set value, the controller 7 controls the power of the air supply device 1, and thus the pressure and amount of the transport liquid, based on the values fed back by the pressure sensor 91 and the flow meter 92. The setting value may be set by the operator, may be a fixed value set by the operator, may be a setting value set according to different operating environments or different operation types, may be set according to needs, and is not particularly limited herein.
In other embodiments, the pressure sensor 91 may be disposed at any position in the line from the liquid feeding pipe 51 to the second line 62, and the flow meter 92 may be disposed at any position in the line from the liquid feeding pipe 51 to the second line 62, and the specific arrangement may be set according to the requirement. By providing the flow meter 92, the real-time flow and total volume of fluid delivered by the device into the body lumen can be precisely controlled. More specifically, the controller 7 can acquire data of the flowmeter 92 and the pressure sensor 91 in real time, and based on the acquired data, control the real-time flow rate and the total amount of the liquid to be delivered into the human body lumen in real time, control is more accurate, and operation is more intelligent. When the acquired data is calculated to obtain the pressure in the cavity (e.g., in the uterus), the power of the air supply device 1 can be controlled according to the pressure in the cavity. For example, the number of pressure in the patient's cavity can be detected by the pressure of the liquid or gas in the endoscope channel, and when the pressure in the cavity increases to a set dangerous value, the controller 7 reversely controls the air supply device 1, reduces the power of the air supply device 1, reduces the delivery amount of the gas, and improves the control accuracy.

When the liquid in the liquid bottle 2 needs to be replaced, the first three-way valve 3 and the normally closed valve can be disconnected without removing the liquid bottle 2, for example, the liquid feeding button 82 and the air feeding button 81 on the handle 300 are loosened, the first normally open mouth 951 and the first normally closed mouth 952 are communicated, and the liquid in the liquid bottle 2 is pumped out through the liquid pumping pump; after the liquid in the liquid bottle 2 is drawn out, the first normally-open opening 951 and the second normally-closed opening 953 are turned on, and the first normally-closed opening 952 is closed, at which time the liquid, such as a developer, can be injected into the liquid bottle 2. In this embodiment, the first normally-closed port 952 is connected to the fluid pump via a luer fitting.
The three-way valve of the second three-way valve 95 may be rotated to selectively conduct the first normally-open port 951 and the first normally-closed port 952, or the first normally-open port 951 and the second normally-closed port 953, thus facilitating the operation. The second three-way valve 95 may be electrically connected to the controller 7, and the controller 7 may control the opening and closing of the first normally-closed port 952 or the second normally-closed port 953. The air supply device 1 may be an air pump, or may be other devices capable of supplying air, and the air supplied by the air supply device 1 may be carbon dioxide, or may be other gases harmless to the human body, and may be specific according to the working environment or requirements.

In addition, in the control method, the control method further includes:
step S430, the pressure and the flow of the liquid in the operation cavity channel are obtained in real time;
