INDIVIDUAL DEVICE FOR PROTECTION OF RESPIRATORY ORGANS FROM INFECTION

FIELD: medicine.SUBSTANCE: group of inventions relates to medical equipment, specifically to versions of an individual device for protecting respiratory organs from infection. In the first version, the device comprises a half-mask. Half-mask is made in the form of a housing having free undermask space, conjugated with: inspiratory-expiratory valves of petal type. Half-mask has a nose clamp fixing a half-mask in the nose bridge area, elastic straps of the headband, and also through its base with a support element with a case which contains a filter element, bactericidal radiator in the form of a radiation source connected to a control unit and a power supply. Device is equipped with portable hardware enclosure of control unit. Control unit includes: a control board, a battery, a power supply, a generator of high-voltage electric pulses, an air flow sensor and an ozonizer, connected by a branch pipe supplying the ozone-containing air mixture, with a bactericidal radiator, made in the form of a replaceable single-cell case mounted in a support element of the housing, which includes a reaction chamber in the form of a polymer shell conjugated with a hollow metal cylinder, the inner surface of which is made mirror-like. Reaction chamber is limited, at the inlet end - with a supporting plate filter made of metal of cellular structure with fixed holder and installed in it, electric-discharge unit connected to generator of high-voltage electric pulses of power supply source, exciting plasma-dynamic spark discharges, light quanta of which in the UV radiation wavelength range of 2,300-3,000 Å provide pulsed photolysis of ozone from the ozone-containing air mixture to obtain highly active forms of oxygen, and at outlet end of reaction chamber - combined filter, including plate filter of metal of cellular structure, conjugated with deactivator of residual ozone in form of porous capsule-filter filled with capillary-porous carbon material. Device is equipped with a transparent face shield connected to a resilient-deformable holder located on the nasal clamp of the half-mask. Device is equipped with a pad, which is permanently connected to the half-mask along the obturation band contour. Device is equipped with replaceable disk-like resilient-elastic washers, which are plugs of uncontrolled petal-type inspiratory-expiratory valves. In the second version, the device is equipped with a semiconductor UV light-emitting diode. In the third version consists of two reaction ch
