Known INDIVIDUAL NOSE FILTER patent RU 108304 U, publ .: 2011.09.20, which is designed to filter the air inhaled through the nose. An individual nasal filter contains a frame made of a soft and elastic material in the form of two identical tubes connected by a bridge, a filter material and two adhesive tapes, characterized in that the frame is made monolithic, while adhesive tapes are attached to the end of the tubes of the frame to hold the tubes of the frame with filter material at the level of the nostrils.

Air purification in the filters listed above is carried out due to the fact that when inhaled, air passes through filter elements made of various materials, leaving atmospheric pollution and allergens in them. The filter elements are the main component of the above filters. However, the presence of these filter elements, blocking the free access of air, creates a significant resistance to the inhaled air flow, which significantly complicates breathing.

Known breathing filter designed to protect the respiratory tract from dust and allergens contained in the inhaled air, characterized by the presence of an air channel free from filtering materials (US Patent 5787884, IPC: A61G 10/00; A61M 16/00; A62B 7/10; A62B 23/02). This filter is a body made of elastic material, the shape of which allows it to be placed in the nasal cavity. Inside the filter, a curved air channel is made, which has zones for collecting dust particles, covered with an adhesive substance, located in close proximity to the places where the channel direction changes. Due to the specified shape of the channel, the inhaled air changes its direction of movement many times. In this case, dust particles contained in the inhaled air are deposited on the adhesive coating.

However, in this technical solution, in order to improve the quality of cleaning the inhaled air, it is necessary to make the channels sinuous with a minimum diameter, which also has a noticeable resistance to the air flow passing through the filter, which increases as the filter becomes dirty.

Known breathing filter (Patent RU 2166341, IPC: A62B 23/06), containing a hollow body, equipped with at least one inlet channel, having an adhesive coating on the inner surface, capable of retaining dust particles and allergens contained in the inhaled air ... In this case, the inner surface of the body has the shape of a truncated cone, and the mentioned one or more inlet channels are made with an inlet from the side of the larger base, the outlet from the side of the small base of the cone, while the direction of the axis of each of the channels is made up of tangential and axial components. The surface of the inlet channels and / or the outer surface of the large base of the housing are coated with the mentioned sticky substance.

However, the constructive solution of the channel in the known breathing filter does not provide the quality of cleaning the inhaled air.

FIG. 2 shows the principle of using the utility model.

In the drawings: 1 - body, 2 - retainer, 3 - protective cover, 4 - antibacterial material, 5 - UV LED, 6 - battery, 7 - porous filter, 8 - air flow, 9 - nasal passage, 10 - columella , 11 - through channel inside the body.

Implementation of the utility model

An individual nose protection device has a body 1 (see Fig. 1) designed to be fixed in the nose, provided with a retainer 2, which is made in the form of a staple part with holders equipped with tips that can be fixed to the device body.

What is new is that in the upper part of the housing 1, between the arches of the clip-shaped retainer 2, there is an antibacterial material 4, and in the lower part of the housing there is a UV LED 5 connected to the contacts of the battery 6 located inside the housing 1.

This device provides antimicrobial protection against inhaled and exhaled air through the nose and mouth due to the fact that the air 8 (see Fig. 2), before entering the nasal passage 9, passes through the antibacterial material 4 located in the lower part of the body, and the air itself in front of getting into the antibacterial material 4 is additionally disinfected with UV-LED 5, which has a range of up to 10-15 cm.

Due to the fact that the means for air disinfection are located outside the nose, and not inside the nasal passages 9, the utility model provides comfortable wearing in the nose.

The attachment of the device in the nose is carried out by pressing the ends of the retainer 2 to the columella 10 of the nose (see Fig. 2).

As an antibacterial material, mesh and porous materials can be used, for example, gauze, fabrics, fine nets, cotton wool and others, which are impregnated or moistened with antibacterial substances, for example, eucalyptus oil, garlic, camphor oil.

If a cover 3, opaque to UV radiation, is installed in the lower part of the housing 1 around the UV LED 5, then the skin of the face is protected from the harmful effects of ultraviolet radiation from the LED 5.

If through channels 11 are additionally made inside the housing 1, going from the bottom to the upper part of the housing 1, and porous filters 7 (for example, a sponge) are installed inside them, then the degree of purification of the air entering the nasal passages 9 will increase even more.

In addition, the plafond 3 accumulates heat around the LED 5 and thereby creates a heat flux, which will tend to get out of the plafond 3 upward in a faster flow than the air 8 left without it. Therefore, the presence of through channels 11 enhances this air flow and directs it through the antibacterial material 4. Strengthening the air flow going through the channels 11 allows you to reduce the mass of air that passes into the nose, bypassing the antibacterial material 4, which increases the effectiveness of antibacterial and antiviral protection ...

In addition, the effect of the total impact on the airspace, especially in confined spaces, from the use of this device can be noted. The more individual devices are used, the stronger the disinfecting effect will be, since the inhaled - exhaled air will be repeatedly treated with a bactericidal barrier.
