When the suction unit of a compartment fails, it is often not possible to maintain the negative pressure of that compartment, which, if used, may be a multiple infection situation. Therefore, when the air extracting unit of one compartment fails, the air of the compartment is extracted by controlling the air extracting units of the adjacent compartments, the normal use of the compartment is ensured, and the risk of multiple infections is reduced. Particularly, when the compartment resources are in shortage, one more patient can be accepted and treated when one more available compartment is available.

In this embodiment, the external air pressure refers to the air pressure outside the negative pressure tent.
EXAMPLE III
The difference between this embodiment and the second embodiment is that, in this embodiment, the control module further includes an image acquisition unit, and the image acquisition unit is used for acquiring image information of a person entering the airlock 2. The processing unit is also used for acquiring image information of the personnel entering the air lock chamber 2 from the image acquisition unit, judging whether a patient exists in the personnel entering the air lock chamber 2 or not based on the image information, and if so, controlling the air pumping unit in the channel 4 to increase the power so that the air pressure in the channel 4 is equal to the air pressure in the compartment 3. In this embodiment, the image acquisition unit adopts the camera, and the processing unit judges whether there is the patient in the personnel that get into airlock 2 based on image information is very mature image recognition technology, for example gets rid of medical personnel through the clothes, and what the remaining coincidence is the patient, and here is no longer repeated.
Since the patient is probably contagious, if the air pressure in the passageway 4 is greater than the air pressure in the compartments 3, the air in the passageway 4 can easily enter each compartment 3 after the patient passes through the passageway 4, and the patient in the compartments 3 is at risk of multiple infections, and by making the air pressure in the passageway 4 equal to the air pressure in the compartments 3 before the patient enters the passageway 4, the amount of air flow between the passageway 4 and the compartments 3 after the patient enters the passageway 4 can be reduced, and the risk of multiple infections can be reduced. The solution of the present embodiment allows to reduce the energy consumption compared to always keeping the air pressure inside the channel 4 equal to the air pressure inside the compartment 3. Since there is not only a patient but also a medical person who enters the airlock 2, the pressure in the passage 4 is not adjusted when only the medical person enters the airlock 2 because the medical person does not have the infectivity.
