The mobile “Huo-Yan” series provides a set of prevention and diagnosis products for nucleic acid testing for the prevention and control of epidemics in various countries. The solutions include laboratories and isolation wards that can quickly respond to outbreak needs through an internal negative-pressure environment and a stowable, foldable format. The testing equipment is prefabricated inside the Huo-Yan Cube Laboratory, which is placed on a vehicle and can be driven on site for localized screening as soon as demand is received; then the Huo-Yan Air Laboratory is transported by air to the demand site, inflated, and set up for mass testing.
