INDIVIDUAL AND MOBILE BIOLOGICAL PROTECTION DEVICES BY IRRADIATING FLOWING AIR WITH ULTRAVIOLET RADIATION Russian patent published in 2020 - IPC A62B7/00 

FIELD: individual protection systems.

SUBSTANCE: invention can be used for creation of personal respiratory protection systems (PRPS) and vision from pathogenic microorganisms propagating by air and aerosol. Device for inactivation of pathogenic microorganisms in air flow is made in form of flow chamber having inner volume and at least one wall limiting such inner volume. Inner chamber volume accommodates at least one light-emitting diode (3) of ultraviolet radiation spectrum. Entire inner surface of at least one said wall is coated or made of material reflecting ultraviolet radiation (4) to form a multipass optical system. In at least one said wall there are at least two through slits or holes (5), one of which is essentially inlet, the second – output from condition of passage of air flow through internal volume of chamber. Also disclosed are an individual respiratory protection device and an air disinfection device.

EFFECT: providing effective protection against airborne infections in large rooms, accessibility and ease of use for the absolute majority of the population and workers of enterprises, low power consumption, absence of parasitic heat release, small size and weight of the device.
