A few days ago, a high-protection "tent" laboratory was put into use in Wuhan to provide equipment support for research on new types of coronavirus detection, detection reagents, and vaccine antibodies.

For the detection of new types of coronavirus, with the kit, it is also necessary to ensure the safety of the test personnel and the escape of pathogens under closed and negative pressure experimental conditions, but not all hospitals have such a laboratory for a long time.

"The laboratory protection level is usually not high, and it is necessary to provide detection and protection equipment." Qi Jiancheng, director of the Institute of Military Support Technology of the System Engineering Research Institute of the Academy of Military Sciences, told the reporter of Science and Technology Daily that as early as January 23, their team from Tianjin Travel to Wuhan to provide testing and protective equipment for the hospital's testing laboratory and carry out transformation.

With the development of the new coronavirus pneumonia epidemic, the lack of qualified laboratories and the conditions for rapid transformation of hospitals is becoming increasingly prominent. More research including new coronavirus detection, testing reagents, and vaccine antibodies have protection levels Request. To this end, a new type of tent-type mobile laboratory developed by the Institute of System Engineering, Institute of Military Engineering, Academy of Military Sciences arrived in Wuhan for support.

Tent mobile laboratory is a new type of mobile laboratory model that can be deployed in situ. Tent-type laboratories are characterized by rapid deployment, large space, high protection level, and low cost.

Tent laboratory consists of technical support cabins and protective tents

"The mobile laboratory consists of two parts, including the technical support cabin and protective tent." Qi Jiancheng introduced that the technical support cabin provides technical support for the tent laboratory, such as ventilation and air conditioning systems, automatic control and alarm systems, and video surveillance systems; The tent laboratory consists of a core experiment room, a buffer room, a sample receiving room, and an experiment preparation room.

"Negative pressure" is the key to protecting the laboratory and the environment and between the laboratories. Negative pressure is formed in the laboratory and the outdoor environment through the automatic control of the supply and exhaust of the new wind DC ventilation and air-conditioning system. The negative pressure is stably controlled at -30Pa ± 5Pa. Inside the laboratory, the negative pressure in the core experiment room and the buffer room is stable. At -10Pa ± 5Pa. "When the pressure deviates from the above range, the automatic control and alarm system will activate audible and visual alarms, and automatically start emergency measures such as closing the supply air and increasing the exhaust air." Qi Jiancheng said that the real-time monitoring of the equipment in the technical support cabin ensured that The air outside the core experiment room can only flow inward, the airflow in the experimental area is directed from the clean area to the relatively polluted area, and the air in the core experiment room and the buffer room is efficiently filtered and discharged to ensure the safety of the environment outside the laboratory.

In addition, the technical support square cabin also serves as the transportation square cabin, which can contain protective facilities and equipment such as transportation protective tents, high-efficiency exhaust filtering devices, small pressure steam sterilizers, and flexible glove box-type negative pressure biological isolators.

The term "packed" in a tent-type mobile laboratory can be described as "compact and capable". Its size is equivalent to a standard 6-meter container. It can be quickly transported to the scene of a new infectious disease epidemic by road, rail, ship or air transportation. It can quickly implement the isolation, cultivation and verification of pathogens for emergency prevention and control of the epidemic. Provide strong technical and equipment support.

According to reports, after the tent-type mobile laboratory arrived in Wuhan, it was quickly launched in situ and put into epidemic prevention and control work. It also set up a scientific research platform for the military medical expert group led by Chen Wei, an academician of the Chinese Academy of Engineering, to detect new coronavirus , Testing reagents and vaccine antibodies provide equipment support.
