DESCRIPTION

The device refers to personal protective equipment for the respiratory organs of humans or animals from pathogenic bacteria and viruses, as well as from dust particles carrying allergens, and can be used as a protective bactericidal and viral barrier for the prevention of diseases.

From the prior art, various technical solutions are known for individual means of protecting the respiratory organs of a person from harmful environmental influences.

Most often, cotton swabs impregnated with an antibacterial agent and placed in the sinuses are used as a similar solution. This option makes breathing very difficult, is inconvenient during operation.

Known breathing filter (Patent US5117820, IPC: A62B 23/06), consisting of a filter element, which is an elongated cylinder of synthetic porous material. The structure of the material of the filter element allows it to be compressed in the radial direction for unobstructed installation in the nasal cavity, after which the material expands and the nasal cavity is filled. When inhaling, the pores of the filter element allow air to pass through, trapping harmful components.

Known replaceable filter for the respiratory tract, installed in the sinuses (Patent RU2217176, IPC: A61M 16/00). The replaceable filter is a truncated cone filter element made of elastic porous material for medical use. The truncated cone is provided with circular notches that ensure reliable retention of the replaceable filter in the nasal cavity and its tight fit to the walls of the sinuses, while the lower and upper bases of the cone have concave cone-shaped hollow funnels. The filter element can be impregnated with drugs.

Known patent RU96329U, publ .: 2010.07.27 for a breathing filter, which is placed in the human nasal cavity and includes a body with a through cavity, made mounted with the possibility of placing in the human nasal sinus, the filtering element, fixed in the inlet channel, at least one non-return valve. The casing is equipped with at least two air ducts - inlet and outlet. The check valve is located in the outlet channel with the possibility of preventing the inhaled air flow from entering the human respiratory system through the outlet channel. The technical result is to increase the efficiency of trapping harmful components contained in the surrounding atmosphere, while providing more free breathing through the inventive device.

Known air filter for the nasal cavity according to the patent RU182556U, publ .: 2018.08.22. In the air filter for the nasal cavity, containing the filter elements connected to each other by a flexible element for placement on the nose, the filter elements are made in the form of a three-layer ellipsoid. The central part of the ellipsoid is made of a material with absorption properties (activated carbon, silica gel) and is provided with a shell of a porous material (nonwoven spunbond or spunlace), they are located in the body of the ellipsoid, which is a mesh of soft polymer (polyethylene).

Known AIR FILTER FOR PROTECTING NASAL RESPIRATION under the patent RU2655004, publ .: 2018.05.23, which essentially consists of filtering components and a connecting element. Two filtering components have a conical shape made of plastic material and an internal hole with a replaceable filter unit and are connected with a thin, flexible, plastic material of any color. This filter also provides the option of using replaceable filter units to ensure long-term use of the air filter. Due to its shape, the filter can be used for medical purposes, allowing the muscle of the wing of the nose to expand, thereby improving breathing in humans with nasal congestion. The technical result consists in increasing the effectiveness of the air filter as an antibacterial, antiviral and antiallergenic means of protection in public places with a large congestion or passing of people, providing free nasal breathing and using the same size of the universal filter for different internal entrance forms of the nose. The filter is easy to manufacture, allowing for mass production of lightweight, efficient, economical filters, easy to use.

Known FILTER FOR THE NOSE CAVITY according to patent RU2418609, publ .: 2011.05.20, having a substantially cylindrical bearing wall adhering to the walls of the nasal cavity, and an inner surface defining a cavity for the passage of air inhaled and exhaled by the user. The cavity contains a series of plates that create turbulence in the flow of air flowing, and the surface exposed to the air retains the particles present in the air.

Known DEVICE FOR PROTECTION OF THE HUMAN RESPIRATORY ORGANS RU113150U, publ .: 2012.02.10, which is located in the nasal cavity and includes a body with a through cavity, made with the possibility of placement in the human nasal sinus, a filter element fixed in the inlet channel at at least one non-return valve. The body is equipped with at least two air passages - inlet and outlet. The check valve is located in the outlet channel with the possibility of preventing the inhaled air flow from entering the human respiratory system through the outlet channel.

Known INDIVIDUAL NOSE FILTER patent RU108304U, publ .: 2011.09.20, which is designed to filter the air inhaled through the nose. An individual nasal filter contains a frame made of 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 frames 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 part 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 of filter materials (Patent US5787884, 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. A curvilinear air channel is made inside the filter, 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 RU2166341, IPC: A62B 23/06), containing a hollow body, equipped with at least one inlet channel, having on the inner surface a coating of an adhesive substance capable of retaining particles contained in the inhaled air dust and allergens. 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 said sticky substance.

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

The closest analogue is the DEVICE FOR RESPIRATORY PROTECTION RU2441676, publ .: 2012.02.10, which includes two bodies, made with the possibility of placement in the nasal sinuses, each of which has inlet and outlet openings, while the inner surface of the body is covered with a layer sticky substance, characterized in that it is equipped with an element for redirecting the air flow, fixed in the cavity of the body on the axis, a retainer connecting the two bodies from the side of the inlet openings, while the body is equipped with a mesh element located from the side of the outlet.

The device is equipped with a sealing ring located along the edge of the body around the inlet, while the body is cylindrical in shape.

The air flow redirection element is made in the form of sections of the volumetric tape spiral rigidly fixed on the axis.

The latch is made in the form of a bracket-shaped part with holders equipped with tips made with the possibility of fixing to the device body. The technical problem of the prototype and other known analogs is the discomfort experienced by the user when wearing inserts inside the nasal passages.

The technical result is to provide antimicrobial protection of inhaled and exhaled air through the nose while wearing the device comfortably in the vicinity of the nose.

The specified technical result is achieved due to the fact that an individual nose protection device is declared, including a body made with the possibility of being fixed in the nose columella, equipped with a retainer, which is made in the form of a staple part with holders equipped with tips with the possibility of fixing. to the device body, characterized in that an antibacterial material is located in the upper part of the body between the arcs of the clip-shaped retainer, and a UV-light-emitting diode is installed in the lower part of the body, connected to the contacts of the battery located inside the body.

Preferably, in the lower part of the housing, around the UV LED, a cover is installed which is opaque to UV radiation.

Preferably, through channels are provided inside the housing, extending from the bottom to the top, and porous filters are installed inside the channels.

Brief Description of Drawings

Figure 1 shows the claimed device.

Figure 2 shows the principle of using the device.

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

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

The novelty is that antibacterial material 4 is located in the upper part of the housing 1 between the arcs of the clamping retainer 2, and a UV LED 5 is installed in the lower part of the housing, connected to the contacts of the battery b 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 air 8 (see Fig. 2), before entering the nasal passage 9, passes through antibacterial material 4 located in the lower part of the body, and the air itself, before entering the antibacterial material 4, is additionally disinfected with a 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 inside the body 1 additional through channels 11 are made, going from the lower to the upper part of the body 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 is even greater. will rise.

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 makes it possible to reduce the mass of air that passes into the nose, bypassing the antibacterial material 4, which increases the effectiveness of the antibacterial and antivirus 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.
