This invention discloses a portable UV and hydrogen peroxide co-sterilization device for biosafety sample collection and delivery packaging. The device employs a double-layered insulated enclosure, with a UV sterilization lamp at the top and an atomizing hydrogen peroxide nozzle on the inner wall. The atomizing nozzle sprays micron-sized aerosol particles to achieve omnidirectional dispersion of the aerosol medium within the sealed space, combined with the UV light source arrangement design to eliminate sterilization dead zones. An adjustable partition inside the enclosure allows for flexible separation of samples of different sizes, preventing cross-contamination. Ventilation holes in the enclosure walls balance internal and external air pressure, ensuring product safety. An environmental monitoring module at the bottom monitors temperature and humidity data in real time and displays it on a screen outside the enclosure, providing visualization of the internal temperature and humidity. This invention facilitates dual sterilization and is adaptable to various pathogenic microorganism disinfection scenarios, possessing characteristics such as impact resistance, corrosion resistance, non-destructive sample handling, and environmental friendliness.
