PERSONAL RESPIRATORY PROTECTION DEVICE Russian patent published in 2020 - IPC A62B7/10 

FIELD: satisfaction of human vital needs.

SUBSTANCE: invention relates to protection of human respiratory apparatus, in particular to individual means with filtering elements, and can be used as a means of protection when being in conditions of dust, bacterial and other environmental pollution. Device is made in the form of spectacles with a rim having a frontal part, temporal parts adjoining the frontal part on both sides and temples attached to the temporal parts. Each temporal part comprises a suction fan with an air filter and a discharge air duct, wherein the air duct is made outputting from the temporal part of the rim and continuing at the bottom of the frontal part of the rim so that the nozzles of both air ducts are oriented oppositely to each other with possibility of formation of substantially counter directed air flows directly under user's nostrils when using device. Due to said arrangement of nozzles, directly under nostrils two oppositely directed clean air streams are formed, which, when colliding, form a high-pressure area, which prevents ingress of untreated outer air into nostrils.

EFFECT: as a result, the user inhales air filtered and supplied by fans through air ducts.
