PHOTONIC QUANTUM MECHANICAL (PQM) PROTECTIVE MASK Russian patent published in 2021 - IPC A41D13/11 

FIELD: medicine; protective antiviral medical masks.

SUBSTANCE: mask is equipped with air filters and an ultraviolet radiation source located inside the bactericidal chamber. The source of ultraviolet radiation is made in the form of a small-sized UV-C LED, and the bactericidal chamber is made in the form of a spheroidal closed cavity with an equivalent radius R, the surface of which is perforated with holes with a diameter of d<R. The air filter of the bactericidal chamber is made in the form of a spheroidal shell. At the outlet of the air chamber, an additional anti-ozone air filter that does not pass ozone and an inlet air valve are installed. On the front part of the mask housing, an LED indicator and a second bactericidal chamber are installed, similar to the first, with a valve for releasing air. In addition, photovoltaic detectors are installed in the second bactericidal chamber to measure the level of radiation caused by the glow of viruses under the influence of UV radiation.

EFFECT: technical result of the invention is aimed at improving effectiveness of protecting the mask carriers and the people around them from viruses.
