The present application belongs to the technical field of
ultraviolet disinfection, and particularly relates to a medical infection prevention and control
ultraviolet disinfection device, which comprises a casing, an air inlet
pipe and an air outlet
pipe are arranged on the casing, an air flow channel is formed in the casing, an
ultraviolet lamp is fixedly arranged in the air flow channel, a reflection
assembly comprises at least one reflection blade, the reflection blade has a reflection surface, and the reflection blade is rotatably arranged on the periphery of the ultraviolet lamp. The present application is characterized in that the rotatable reflection blade is arranged around the lamp tube, the high-reflection
coating reflection surface realizes directional strengthening projection of
ultraviolet light, the
microstructure scattering surface realizes multi-angle uniform
diffusion, the rotation movement makes the light path dynamically cover the whole space of the air flow channel, the direct blind area and the disinfection dead angle are completely eliminated, the uniformity of the
ultraviolet light intensity and the
energy density in the flow channel are significantly improved, it is ensured that the air flowing through the air flow channel can receive sufficient
irradiation, the efficient inactivation of pathogenic microorganisms is realized, and the probability of
cross infection in the hospital is greatly reduced.
