Background
The main transmission routes of the novel coronavirus are droplet transmission, contact transmission and the like. The droplets are generally spread by coughing, sneezing and the like, have a limited propagation distance in the air, settle quickly after coming out of a human body, and cannot float in the air, but the movement range of the droplets is obviously enlarged under the working state of an air conditioner. When an epidemic situation occurs, as all cabins of a ship share one central air conditioner, air with viruses can be transmitted through air inlets and air outlets of the cabins of the ship, and the situation that one person is sick and the whole ship is infected is likely to occur. Therefore, when an epidemic situation occurs, the isolation cabin for receiving patients on the ship is effectively isolated, and the isolation cabin is very important for preventing the spread of viruses.
At present, in order to control the spread of viruses and prevent cross infection in the treatment process, a hospital mostly adopts the design of a negative pressure isolation ward to an infectious disease ward. Firstly, the flow direction of air flow is strictly controlled by adopting a differential pressure control technology, so that air flows from a clean area to a polluted area under the driving of effective pressure gradient, and the phenomenon of air flow backflow is absolutely avoided; the other is to perform the setting of three-zone two-channel. Three areas are a cleaning area, a semi-polluted area and a polluted area; the two channels, namely medical staff, medical supplies and the like enter the infectious disease ward from the clean working channel of the medical staff, the patient enters the infectious disease ward from the polluted patient channel, and an independent sewage outlet is additionally arranged for transferring medical wastes. Medical personnel can enter the ward from the clean passage through the buffer room to treat the patient. After the treatment is finished, the patient needs to pass through a passage from the ward to the semi-polluted area, and reaches the disinfection room area to carry out the processes of taking off the protective clothing → washing and disinfecting → changing the clothing and washing and disinfecting, and the patient can return to the clean passage again after reaching the clean standard. Compared with the prior art, the ship cabin is not designed to be a negative pressure isolation cabin, so that an effective air pressure gradient cannot be formed during an epidemic situation, the flow direction of air flow is strictly controlled, and the air flow from a clean area to a polluted area is ensured. On the other hand, the space of the ship cabin is narrow, and the setting of three areas and two channels in an infectious disease ward can not be realized during the epidemic situation, so that the ship personnel are prevented from being infected by viruses.
