FACE MASK WITH ULTRAVIOLET DECONTAMINATING AGENT Russian patent published in 2021 - IPC A41D13/11 A62B18/02 

FIELD: medicine.

SUBSTANCE: proposed inventions relate to medicine, namely to masks for medical purposes, and can be used as a means of individual protection against viral and bacterial infections transmitted by airborne droplets mainly in medical institutions, during epidemics of viral and infectious diseases. Face mask with ultraviolet decontaminating agent (version 1) consists of attachment means to the face of the mask wearer and ultraviolet decontamination device in its housing, located in the front face of the mask, while ultraviolet decontamination device is equipped with ultraviolet radiation source located inside the housing of the ultraviolet decontamination device, while the ultraviolet radiation source is connected to the power supply unit. Mask is equipped with a valve for inhaled and / or exhaled air, while partitions are installed inside the ultraviolet disinfector so that inhaled and exhaled air has possibility to pass the maximum path between the sources of ultraviolet radiation at the minimum distance from them; while the source of ultraviolet radiation is made in form of blocks of ultraviolet LEDs located in both side walls of the body of the ultraviolet decontaminator along the axis of the partitions; while on the outer surface of the side walls of the body of the ultraviolet decontaminator, radiators for cooling ultraviolet LEDs are made; blinds are installed at the output of the ultraviolet decontaminator, preventing the exit of ultraviolet radiation beyond the limits of the ultraviolet decontaminator; while power supply unit is equipped with power management board for ultraviolet LEDs with ability to maintain constant supply voltage for ultraviolet LEDs; while the inner surface of the ultraviolet decontaminator is made of a material that reflects ultraviolet radiation. Face mask with ultraviolet decontaminating agent (version 2) is characterized by the fact that ultraviolet decontaminating agent is made in form of a block attachment placed separately outside the mask, attached to the mask by means of a flexible hose.

EFFECT: simplified mask design due to the provided possibility of separate disinfection of only inhaled air, only exhaled air, only inhaled and exhaled air simultaneously.
