In a preferred embodiment of the invention, the respiratory protection device comprises a helmet 1 comprising a transparent mask 2 and a flexible membrane 3, an air ventilation tube 4, an incoming air cleaning device 5, a supply tube 6, a pressure regulating valve 7, a discharge tube 8, an outlet air cleaning device 9, a rigid section 10 of the air ventilation pipe 4, a flexible section 11 of the air ventilation pipe 4, an air inlet hole 12 in the helmet 1, and an air discharge opening 13 (
The device for protecting the respiratory organs functions as follows.
Ambient air is supplied to helmet 1 with mask 2 from incoming air cleaning device 5 located on helmet or user's body, which filters external air, increases its pressure, and under increased pressure supplies air through valve for regulation of pressure 7 into supply tube 6. Then air gets into flexible section 11 of front tube for ventilation 4, and then enters its rigid section 10, after which air enters helmet 1 through introducing air 12. Inside helmet 1 external air is inhaled by the user. The user exhales through holes for venting air 13 in rigid section 10 of rear tube for ventilation 4. The air enters flexible section 11 of this tube for ventilation 4 and then enters discharge tube 8, from which it is supplied to device for cleaning of outgoing air 9, located on helmet or body of user, which cleans internal air from aggressive biological substances exhaled by user and outputs the purified air to the outside (
