Description

 The invention relates to sanitary-hygienic prophylactic agents.

 A toothbrush is known that contains a head with a bristle, a neck and a handle, while the bristle is at least partially made of radiation-conducting fibers, the ends of which are optically coupled to the head and the radiation unit is placed in the handle and connected to the power supply (see Patent of the Russian Federation N 2098993, class A 46 B 9/04, 15/00, publ. 20.12.97).

 A disadvantage of the known device is the complexity of its manufacture, the need for energy consumption from a power source and low hygiene due to the lack of bactericidal agents that protect the bristles from the propagation of pathogenic microflora in it.

 Known toothbrush (see US Pat. RF N 2039483, class A 46 B 9/04, publ. 07/20/95), containing a handle, neck, head with bristles and bactericidal agents made of silver, made in the form of rods. In this case, the toothbrush is equipped with an overlay for closing the head bristles, and silver rods are mounted on the overlay and placed in the head bristles.

 The disadvantages of this toothbrush include a low bactericidal effect, since after washing the brush before brushing, most of the silver in the form of oxides is washed out of the bristle carrier, the inability to form microcurrents during the procedure, which ensure the restoration of silver oxides to metal ions, the latter, in turn, form a bactericidal flora in the oral fluid and stimulate an increase in blood microcirculation in the tissues of the lips and gums.

образной пластины с пропиткой антимикробного действия, а в головке со стороны, противоположной щетине, выполнены пазы под пластину, при этом наружная поверхность пластины параллельна рабочему краю щетины.Closest to the proposed invention in terms of essential features is a toothbrush (see AS USSR N 1808293, class A 46 B 9/04, publ. 04/15/93), containing a handle, a neck, a head with bristles and bactericidal element, made in the form of spraying on the head or in the form of a removable

shaped plate with antimicrobial impregnation, and in the head from the side opposite to the bristles, grooves are made for the plate, while the outer surface of the plate is parallel to the working edge of the bristles.

 Although the mentioned toothbrush provides a disinfecting effect when a bactericidal element comes into contact with a liquid in the oral cavity, it does not provide the formation of a galvanic skin current during toothbrushing, and therefore does not stimulate an increase in blood microcirculation in the tissues of the lips and gums. Secondly, the design of the toothbrush does not provide for the possibility of detachable connection of the head with the bristle carrier, and therefore does not provide for the possibility of its single use.

 The objective of the invention is to improve hygiene and ensure the preventive properties of a toothbrush: prevention of inflammatory processes in the oral cavity, healing of microtraumas, toning of the nervous apparatus of local tissues, improvement of blood microcirculation in the tissues of the lips and gums due to the formation of galvanic skin currents in the process of the procedure.

 The technical result - the formation of skin-galvanic currents during toothbrushing - is achieved by the fact that the toothbrush containing the handle, neck, head, which is coated with silver, with bristles, is equipped with a removable additional bristle carrier with the possibility of placing it in the head, while the handle, neck, head are made of electrically conductive corrosion-resistant material, and the handle and neck are additionally coated with silver 5-7 microns thick, and the handle can be equipped with an insert of more of a negative metal or alloy than the material of the neck and head, as well as the fact that, for example, an electrically conductive plastic mass is selected as an electrically conductive corrosion-resistant material, while a coating of a more electronegative metal or alloy is sprayed onto the silver coated handle than silver, and the bristle carrier is enclosed in sealed packaging and is intended for single use.

 The proposed toothbrush differs from the prototype, firstly, in that the handle, neck, head are made of an electrically conductive corrosion-resistant material, and the material of which the toothbrush is made is not specified in the description of the prototype.

 Secondly, the inventive toothbrush is equipped with a removable additional bristle carrier with the possibility of placing it in the head, which allows you to change the latter if necessary.

 Thirdly, in the claimed invention, the handle and neck are additionally coated with silver 5-7 microns thick.

 In the process of brushing, due to the potential difference between the receptors of the skin of the fingers and the oral cavity, a current of 0.3-1 μA appears, which stimulates an increase in blood microcirculation in the tissues of the gums and lips, promotes the healing of microtraumas, tones the nervous system of local tissues, and at the same time silver , which covers the head of the toothbrush, in contact with the liquid in the oral cavity, has a disinfecting effect, kills microbes.

 Fourth, a galvanic pair can be implemented by manufacturing a handle with an insert of a more electronegative metal or alloy than the material of the neck and head, for example, of brass.

 Fifth, in that, for example, an electrically conductive plastic mass is selected as an electrically conductive corrosion-resistant material.

 Sixth, in that a coating of a more electronegative metal or alloy is sprayed onto a silver coated handle than silver, for example zinc or copper, 10-15 microns thick. The manufacture of a brass insert in the handle, as well as the deposition of zinc or copper with a thickness of 10-15 μm on a silver coated handle, increases the efficiency of the procedure: in this case, in a closed circuit, current flows through wet fingers, lip and gum tissue through the oral fluid 10-20 μA, which provides the restoration of silver oxides to metal ions passing into the oral fluid, and the restoration of dissolved oxygen, as well as anodic dissolution of electronegative metal (vst Application of brass or zinc coating applied or copper) on the handle of the toothbrush.

 The current passing in a closed circuit, due to the reduction of silver oxides and oxygen molecules, has a strong bactericidal effect, promotes deeper electrophoretic penetration of nutritious and therapeutic substances of toothpastes into the gum tissue, electrically stimulates the improvement of blood microcirculation in the tissues of the lips and gums.

 Seventh, in that the bristle carrier can be used for single use, therefore it is enclosed in sealed packaging.

 Coating of silver on the handle and neck with a thickness of 5-7 microns is necessary and sufficient for physiological currents to flow from finger receptors to oral tissue receptors.

 A coating of silver with a thickness of less than 5 microns will limit the life of the brush to less than two years due to abrasion and redox processes on silver.

 The thickness of the silver coating is more than 7 microns, due to the high rise in price of the product, due to technological difficulties and an unreasonable increase in the consumption of precious metal, is impractical.

 The coating of the handle of zinc or copper on the applied coating of silver with a thickness of 10-15 microns is optimal for increasing the efficiency of the procedure.

 The smaller coating thickness limits the life of the toothbrush due to the anodic dissolution of the metal.

 A film thickness of more than 15 μm is impractical due to the existing technological difficulties in applying thick coatings.

 Thus, all the signs characterizing the claimed toothbrush are essential, since only, thanks to their combination, a technical result is achieved when using it.

 In FIG. 1 shows a toothbrush coated with silver on the head, neck, and handle; in FIG. 2 shows a toothbrush with a removable bristle carrier; in FIG. 3 shows a toothbrush coated with silver on the head, neck and handle and with a brass insert on the handle; in FIG. 4 shows a toothbrush coated with silver on the head, neck, and handle, on which an additional coating of zinc or copper is applied.

 The toothbrush contains a handle 1, a neck 2, a head 3 with a bristle 4 (see Figs. 1-3, 4) or with a bristle carrier 6 (see Fig. 2). A silver coating 5 is applied to the handle 1, neck 2 and head 3 to ensure the flow of skin-galvanic current.

 The brush is equipped with an insert 7 on the handle 1 of a more electronegative metal, such as brass, to create a galvanic pair: silver-brass.

 The brush is provided with a coating 8 on the handle 1 of a more electronegative metal or alloy than silver, for example zinc or copper, to increase the efficiency of the procedure. The brush is equipped with a removable bristle carrier 6 with the possibility of placing it in the head 3. A sealed packaging of the bristle carrier 6 for a single use is possible.

 Toothbrush is used as follows.

 Rinse the toothbrush with water. Hand grip the handle 1 for the silver coating 5 applied to it, or for the brass insert 7, or for the coating of zinc or copper 8 and begin to make cleaning movements. In the first case, when the brush is held by the coating 5 on the handle 1, when the coating 5 on the head 3 is in contact with the liquid in the oral cavity, the circuit closes and a physiological current of 0.3-1 μA flows from the finger receptors to the oral tissue receptors, exerting bactericidal effect and stimulating an increase in blood microcirculation in the tissues of the lips and gums. When we hold on to the brass insert 7 on the handle 1 or on the additional coating 8 on the handle 1, the skin-galvanic current generated in the circuit closed through the toothbrush increases significantly to 10-20 μA, due to the manufacture of the insert 7 or coating 8 from a more electronegative metal or alloy than silver. The current provides restoration processes in the oral cavity: reduction of silver oxides to metal ions passing into the solution, and restoration of dissolved oxygen. Simultaneously with these processes, anodic dissolution of the electronegative metal of the insert on the handle or coating of zinc or copper on the handle of the toothbrush occurs.

 Physiological and skin-galvanic currents enhance the bactericidal properties in the oral cavity, stimulate deeper penetration of the nutrient and therapeutic substances of toothpastes into the gum tissue, improve blood microcirculation in the tissues of the lips and gums, promote healing of microtraumas, and tone the nervous system of local tissues.

 The proposed toothbrush is made with a removable additional bristle carrier 6 with the possibility of placing it in the head 3, which allows you to make the bristle carrier 6 disposable, sterilizing it and enclosing it in sealed packaging, which meets the requirements of the time, taking into account environmental pollution, for example, water and air, as well as exclude the possibility of using a toothbrush by someone. The proposed toothbrush can be used in the traditional form without additional removable bristle carrier.

 Based on the foregoing, the toothbrush has a high hygiene, it is convenient to use.

 The toothbrush is made of environmentally friendly materials, its sterilization is not difficult.
