Method and Device for the Protection of a Resiratory Tract

Method for the protection of a respiratory tract, where a surrounding air is conducted (directed) through a respirator-working-body, and after that this air is conducted into the respiratory tract, where the surrounding air goes directly in the nose openings (in the nostrils), after that the air is further streeming through the placed in the nasal cavities respirator-working-body, where the whole respirator-working-body is placed completely in the both nasal cavities, and where the respirator-working-body consists of the two parts (below they are named as “RWB-parts”), which RWB-parts are fixed on the internal walls of the sides of the nose, or on the nasal septum, or both, and besides, among other ways of fixing, the both above mentioned RWB-parts are connected with a joint (connection), which one rests (sets) against the nasal septum from below, and therewith prevents a further moving of the a.m. RWB-parts in the upper respiratory tract, and after that the air further streems in the upper respiratory tract,

• where in the each inspiration (breath-in) phase a filter is newly formed (created) by the air, which one goes up in the respiratory tract, and therewith the breathed-in air is further conducted into the upper respiratory tract through this filter;
• and in the each exhalation phase this filter inside the respirator-working-body is disassembled again, and therewith the exhalated (breathed-out) air is conducted away (to outside) through the respiratory-working-body without additional resistance and filtration, where a dust, which one was accumulated in the filter during the breath-in phase, is again conducted away (to outside), completely or partially, during the exhalation (breath-out) phase, and therewith the respirator-working-body cleans itself by itself.
