Description

The utility model relates to medical equipment, namely, to the field of personal hygiene of a person and to sanitary-hygienic accessories, and can find application in denture practice as a tool for cleaning removable dentures.

Known devices for ultrasonic or vibration cleaning of removable dentures, which are flushing chambers with sources of ultrasonic vibrations or vibration oscillators, electric heaters, temperature sensors, etc.

[see, for example, A.S. USSR No. 902874, IPC B 08 B 3/12, decl. 05/05/1980, publ. 02/07/1982; Sec. RF No. 2201722, IPC A 61 C 17/20, declared 05/15/2001, publ. 04/10/2003; Sec. RF No. 2202306, IPC A 61 C 17/00, declared 05/15/2001, publ. 04/20/2003; p. of the Russian Federation No. 2231333, IPC A 61 C 17/02, declared 3.02.2003, publ. 06/27/2004; h. RF №2002131132, IPC A 61 C 17/16, declared 11/19/2002, publ. 05/20/2004].

Also known devices for the electromechanical cleaning of removable dentures, consisting of handles with microelectric drives and cleaning heads having various shapes and configurations.

[see, for example, s. RF №2001115617, IPC A 61 C 17/16, decl. 06/06/2001, publ. 03/10/2003; h. RF №2004100223, IPC A 46 B 13/02, declared 06/06/2002, publ. 02/10/2005].

Although the known devices provide high-quality cleaning of removable dentures, their use is limited due to manufacturing difficulties, design complexity and high cost.

In addition, traditional brushes for cleaning removable dentures (or teeth and oral cavity) are widely known, containing heads with uniform tufts of bristles and handles, which are extensions of the heads. The bristles, heads and handles can have various shapes (flat, voluminous, hollow, solid or open at one end, rotary, etc.).

[see, for example, s. RF No. 2003103775, IPC A 46 B 3/22, declared 06/28/2001, publ. 06/20/2004; h. RF №2003104817, IPC A 46 B 9/04, declared July 16, 2001, publ. 06/20/2004].

The traditional tools described above are quite simple to manufacture, available for widespread use, but have low reliability and do not provide high quality cleaning of removable dentures.

The closest in technical essence and the achieved result to the claimed utility model is a brush for cleaning removable dentures (toothbrush), containing a head with bristles made of synthetic fiber and a handle. Moreover, the front side of the head, along which many tufts of bristles pass, has a rigid peripheral part bounding the hole passing through the head. A mesh of flexible-elastic jumpers forming a lattice having a central part free of jumpers is attached to the peripheral part. At the intersection of the jumpers are nodes with fixed bundles of bristles. The peripheral part of the head, jumpers and handle are made of polypropylene, polyethylene, thermoplastic elastomer or a combination thereof. Synthetic fiber for making bristles is not described.

[cm. p. RF №2244502, IPC A 46 B 9/10, decl. February 9, 2000, publ. January 20, 2005].

During the operation of dental prostheses made of acrylic and other plastics, various structural formations (plaque, tartar, accumulations of various types of microorganisms) appear on their surface, especially on the microreliefs of the prosthesis and the areas between the teeth. Using the prototype brush, you can remove only relatively weakly held dirt (for example, pieces of food) from the surface of the dentures, although the design of the brush provides a snug fit to the three-dimensional curved surfaces of the teeth. The bacterial flora that accumulates on the dentures, the formed tartar and other deposits constantly in contact with the oral cavity adversely affect the body's resistance, hindering the effectiveness of cleaning. Moreover, this brush is made according to a rather complicated foreign technology [see p. US No. 5390984, 5533791] using imported equipment that is not available at domestic enterprises. Therefore, the prototype brush has a high cost and is inaccessible to widespread consumption.

The technical task of this utility model is to offer the mass consumer a simple, reliable, long-lasting brush, providing high efficiency

cleaning removable dentures (palatine areas of the upper dentures, gingival cavities, interdental cavities and other surfaces) from food residues, including plaque, and other contaminants.

The problem is solved in that in the known brush for cleaning removable dentures, containing a head with bristles made of synthetic fiber and a handle, ACCORDING TO THE USEFUL MODEL, the head is made in the form of a brush made of bristles with unprocessed ends fixed in a metal wire frame; the handle is made in the form of a hollow cylinder with a corrugated outer surface; and between the head and the handle there is a metal neck, which is a continuation of the brush frame, the lower half of which is pressed into a continuous plastic cone, which is integral with the handle.

In the brush, ACCORDING TO THE USEFUL MODEL, nylon is used as the synthetic fiber of the bristles; the metal frame is made of stainless steel wire for orthodontic structures, and the cone and handle are made of polyurethane or cellulose copolyester.

The design of the proposed utility model is simple, reliable, has a long service life (up to 1 year) due to the materials used (corrosion-resistant metal and plastic), manufacturing methods (injection molding, pressing); It has high cleaning efficiency due to the increased abrasiveness of the bristles with raw ends and the possibility of bending the metal frame of the brush, which ensures the individualization of the working surface depending on the configuration of the removable prosthesis. These advantages, as well as low cost, make the claimed brush for cleaning removable dentures widely available to the mass consumer. Moreover, the shape of the handle with a corrugated outer surface contributes to the convenience of operation of the protected tool.

Analysis of the known technical solutions allows us to conclude that the claimed utility model is not known from the level of the technology being studied, which indicates its compliance with the criterion of "novelty."

The possibility of manufacturing the inventive brush for cleaning removable dentures from accessible materials by known methods at various enterprises of domestic industry indicates that the utility model meets the criterion of "industrial applicability".

The figure schematically represents the present utility model "Brush for cleaning removable dentures." Designations on a figure:

1 - a brush-shaped head with synthetic fiber bristles fixed in a metal wire frame;

2 - handle in the form of a hollow cylinder with a corrugated outer surface;

3 - a metal neck;

4 - a plastic cone.

The inventive brush for cleaning removable dentures contains a head (1) with bristles made of synthetic fiber - nylon with a degree of hardness - very hard EH-extra hard or hard H-hard. Used threaded bristles without processing ends. The length of the bristles is not more than 10 mm, diameter 0.22 mm or more. The head (1) is made in the form of a brush made of bristles fixed in a metal wire frame made of stainless steel wire for orthodontic structures (TU 64-2-112-76). The number of bristles is not less than 15 pieces per 1 mm of the frame. The bristles are arranged perpendicular to the metal frame in a spiral. Head length 30-32 mm.

The handle (2) is made of polyurethane or copolyester of cellulose in the form of a hollow cylinder with a corrugated outer surface. Handle length not less than 115 mm, diameter 18-20 mm.

Between the head (1) and the handle (2) there is a metal neck (3), which is a continuation of the brush frame, 40 mm long, the lower half of which is pressed into a continuous plastic cone (4), which is integral with the handle (2) and made of the same material as the pen. Using the proposed tool is as follows.

The brush is soaped and the surfaces of removable dentures are cleaned using it by mechanical reciprocating or rotational movements with further rinsing with water.

As can be seen from the description of the design and application, the use of the proposed brush for cleaning removable dentures compared with the known brush taken as a prototype [see p. RF №2244502, IPC A 46 B 9/10, decl. February 9, 2000, publ. January 20, 2005], provides the following technical and socially useful benefits:

- simplicity and reliability of the design;

- high cleaning efficiency;

- ease of use;

- long service life;

- cheapness and accessibility for mass consumption, in particular, for the poor part of the population (pensioners, disabled people, people with limited incomes, etc.).
