Description

 The technical field to which the invention relates.

 The invention relates to respiratory protection of any person, and not only a person, from exposure to harmful environmental factors: dust, various viruses, bacteria, gas, will also provide invaluable help in preventing sudden attacks of allergic effects from exposure to various plant pollen, finally the proposed filter can perform the target individual healing function of the body from painful illnesses if it (the filter) is pre-saturated with a certain medicinal m drug. It will be possible to carry out the drug-impregnation operation not only in the case of mass production, but also in ordinary home conditions on their own, after having received the consultation of the attending physician with what medicine this individual should be treated, especially since the analogy of the alleged treatment with the help of a drug-soaked substance has existed for a very long time. So, for example, they have been treating the respiratory tract, runny nose and nasopharynx with cotton swabs and wicks previously soaked with the necessary medicine. The proposed "replaceable filter in the nose" differs from cotton swabs and wicks in its comfort and accuracy, providing the possibility of the presence of the filter in the sinuses of the nose and to be completely invisible to others at any necessary time, while the natural shape of the nose does not change at all and, most importantly, the filter does not interferes with the respiratory process. The proposed "filter" may be used not only for humans, but also for some animals with the aim of treating them from various diseases, including the effects of allergens.

 The proposed filter can be considered in the future as a means of restoring the immune system, by impregnating the filter element with the necessary medicine.

 The prior art.

 A substantive search for an application for identifying analogues and prototypes. There are several devices and devices using filter elements.

 It is known, for example, "A device for introducing gas into the nasal cavity" (SU 1250307 A1, published 08.1986, 3 pp.). This device has nasal cannulas with tubes for connection to a gas source and a flexible bridge between the cannulas. Each nasal cannula consists of a central support element, etc. Structurally very complex and purely special application.

 The well-known "Air Purifier" (SU 1680213 A1, published September 30, 1991, 2 pp.). The specified air purifier is equipped with internal nasal filters in the form of tortuous rough breathing inhalation channels for liquid substances, it is also supplied with a mouth filter in the form of a tooth insert, which are fixed to each other by a connecting bar to support each other: filters in the nose and mouth.

 The well-known "Tip to inhalers (SU 232478, published 12/11/1968, 2 pp.), By its design and purpose, can only be used in stationary clinical conditions for the introduction of an aerosolite into the nasal and oral cavities.

 A known US patent (3457917, published July 29, 1969), is called "Nasal filtering device." This device also has a nasal filter holder and as a result, this device can only be used in a hospital.

 Finally, US Pat. No. 3,463,149 is known, published August 26, 1969, called "Nasal Air Filter." And this air filter is the closest to the claimed. This air filter has filter swabs inserted into each nostril of a person as cleaning elements. The tampon consists of a wadded wad enclosed in a fabric shell, into which a cylindrical sleeve is placed, and a piston is located inside the sleeve. With the relative movement of the liner and piston, and these movements are carried out manually, by the user himself, the medication is in a cotton swab. In addition, tampons of the legal and left nostrils are interconnected by a supporting device in order to prevent spontaneous prolapse of the tampon from the sinus of the nose.

 All existing devices are very complex in their design, and their use has a narrow purpose in stationary conditions. None of the above analogues solves the main problem of everyday use of the filter in everyday life.

 The problem to which the claimed invention is directed, is to simplify the design of the filter element and the creation of a "replaceable filter in the nose" as a means of individual protection from the environment, as a treating element through the nasopharynx of a person and an animal.

 SUMMARY OF THE INVENTION

 It consists in the fact that the claimed invention "Replaceable filter in the nose" solves the main problem - the creation of a filter element as an everyday individual respiratory protection, and therefore, the whole organism of a living individual from the effects of harmful environmental factors: dust, gas, pathogenic bacteria and viruses that carry allergens. Thus, the claimed invention expands the scope of application of individual daily protection through an individual replaceable filter placed in the sinuses of the nose, in contrast to the analogue of US 3463149. The claimed filter is completely simple in design, since it was possible to eliminate a very complex wadded wad made of cloth, removed and sleeve and piston, as a result, nothing needs to be moved and moved.

 The claimed "replaceable filter in the nose", if necessary, can be impregnated with the necessary drug and will act on the respiratory tract constantly, without any extraneous forced force of exposure. A “replaceable nose filter” is made of a porous elastic material, such as foam rubber or any similar material used in healthcare and medicine. The shape of the filter cartridge is a close shape of a truncated cone with circular notches, as can be seen in FIG. 1, while the bases of the truncated cone are made in the form of cone-shaped funnels. Moreover, the lower wider base of the truncated cone has a curvature directed upward from the base of the truncated cone to the center. The small upper base of the truncated cone also has a curvature directed from top to bottom towards the center. A replaceable filter (see Figs. 1 and 2) is inserted into each sinus of the nose, but completely independently of each other, so it is possible that the user can install the filter in only one sinus of the nose. Circular notches around the circumferences of a truncated cone perform two tasks: the first is the reliable retention of the replaceable filter in the nasal sinus cavity and its tight fit to the walls of the sinuses. And the second purpose is to increase the area of contact of the inhaled air with the filter element, thereby providing a more intensive cleaning of the incoming air flow and the retention of dust particles.

 As mentioned above, the base of the truncated cone, both lower and upper, have the form of some curvature. In the lower wide part of the cone, the curvature is directed upward towards the center (see Fig. 1) and performs two functions: the first is that due to this curvature the filter element is recessed into the sinuses and thereby provides a reliable aesthetic side, i.e. this curvature ensures perfect filter invisibility. The second function of curvature, no less important, is that this curvature increases the area of contact of the incoming air stream with the filter element and thereby helps to more fully clean the air stream entering the nasopharynx (see figures 1 and 2).

 In the upper part of the truncated cone of the filter element there is also a curvature, which, on the contrary, is directed from top to bottom (see Figs. 1 and 2), due to which when installing a replaceable filter in the sinuses of the nose, an air space "a" is indicated, indicated by a dotted line (see Fig. 2 ) Due to the presence of such a balloon, it will be more comfortable for the filter user to overcome the initial adaptation of the presence of a foreign object in the sinuses of the nose, and the second function of the air space “a” is that if the user has an “excess filter in the nose”, an excess liquid is formed, it (this liquid ) can be freely adsorbed by the filter element, having previously got into this recess.

 Bearing in mind that the “Replaceable filter in the nose” is made of elastic material and can be freely and easily removed and returned to the sinuses of the nose directly by the user (if this is a person), the filter can easily be subjected to the necessary hygienic treatment and used again, i.e. e. The filter element can be used repeatedly. The filter change frequency will be determined solely by the user.

 Information confirming the possibility of carrying out the invention.

 The proposed "replaceable filter in the nose" can be made using conventional stamping from an elastic porous material, such as foam rubber or from any similar material used in healthcare and medicine, if this material is sufficiently porous. The configuration of the proposed "replaceable filter in the nose" must necessarily repeat the curve of the sinuses and fit snugly against the walls of the sinuses. This requirement is achieved simply if the element of the replaceable filter (see Fig. 1) is made of an elastic material, then when they are installed in the sinuses of the nose, the filter will take on the shape of the curvature of the nose, and the presence of circular notches will contribute to this. So there are no difficulties in manufacturing the proposed “replaceable nose filter”.

 For ease of manufacture, filters and their sizes can be unified.

 As mentioned above, the proposed shape of the filter is a close shape of a truncated cone with circles in the lower and upper bases (Fig. 1). The drawing is arbitrary, without scale. The height and diameter of the truncated cone will depend on the size of the individual sinuses. So, for example, for adolescence, regardless of whether it is a boy or a girl, it is enough to establish two types of size. Four different types of sizes are set for adult men and women, of which two types of filters for men and two for women.
