Background

Infectious Diseases (Infectious Diseases) are Diseases caused by various pathogens and can be transmitted among people, animals or both, and are characterized by the pathogens, infectivity and epidemics, and immunity is generated after infection. The transmission and prevalence of infectious diseases must have three links, namely, infection sources, transmission ways and susceptible people, and the prevention of infectious diseases adopts comprehensive measures taking the cut-off of the main transmission link as the leading one. Patients with infectious diseases adhere to 'five early', namely early discovery, early diagnosis, early reporting, early isolation and early treatment. Most infectious diseases have the strongest infectivity in early disease, and the early isolation and early treatment of the patients can be realized by diagnosing the patients in time, so that the isolation of the infectious disease patients as early as possible is an effective method for preventing the epidemic situation from expanding.

If the existing epidemic situation is controlled to cause the new coronavirus to cause the global epidemic situation, the key step is to isolate and treat the patient as soon as possible, but the spreading of the infectious disease is rapid and violent, when the epidemic situation is outbreak in a large scale, the medical system of the conventional hospital can not receive a huge infected group because of the limited load, and at this time, the movable negative pressure isolation facility is urgently needed to be adopted to isolate the infected patient as soon as possible, so that the spreading of the pathogen can be inhibited at the first time, and the further spreading of the epidemic situation can be controlled. The negative pressure isolation facility is characterized in that the air pressure inside the facility is lower than the outside, the air flow direction cannot flow outwards from the inside of the facility, and the air polluted by patients inside the facility cannot directly flow to the outside, but is discharged to the outside after being treated by a special air filtering and purifying device.

At present, a container is mostly used as a main body frame of the mobile negative pressure isolation facility, the mobile negative pressure isolation facility is designed in a modularized mode, the container is solid and durable, the transportation of the container consumes time and labor, and the building speed is slow, so that the flexibility of the container type negative pressure isolation facility is greatly reduced.
