DEVICE FOR PHOTOINACTIVATION OF PATHOGENIC BIOLOGICAL AGENTS Russian patent published in 2021 - IPC A61L2/10 F21V8/00 

FIELD: medicine.

SUBSTANCE: invention relates to medical technology, namely to a device for photoinactivation of pathogenic biological agents, including the first group and the second group of radiation sources. The first group consists of radiation sources capable of generating white light with a correlated color temperature value from 3000 K to 6000 K with a beam opening angle of 10 to 180 degrees, and radiation sources capable of generating monochromatic and / or polychromatic ultraviolet light in wavelength range 300-400 nm with a beam opening angle from 10 to 180 degrees. The total spectral irradiance measured at a height of two meters from the floor of the room does not exceed the permissible safe energy exposure. The second group consists of radiation sources capable of generating monochromatic and / or polychromatic ultraviolet light in the wavelength range of 300-400 nm and / or 200-300 nm with a beam opening angle from 10 to 180 degrees. In the presence of people, the established irradiance of ultraviolet radiation sources at a distance of two meters from the floor of the room does not exceed the permissible safe energy exposure. In the absence of people, the established irradiance of ultraviolet radiation sources is not standardized and corresponds to the energy exposure required for photoinactivation of biological agents of I-IV pathogenicity groups in the shortest possible time. The device has a radiator case, the base of which is the base of the MCPCB printed circuit board for supplying power circuits to the first and second groups of light sources and their mounting. The device contains a frame for attaching the device-radiator body to the surface and elements for fixing the device on the surface to be installed. Both groups of radiation sources are made with the possibility of alternating operation.

EFFECT: provision of general lighting and effective photoinactivation of pathogenic biological agents in the largest possible space of the room without adverse or dangerous consequences for people in it.
