Description

 The invention relates to sanitary-hygienic accessories and can be used for the prevention and treatment of diseases of the oral cavity.

 It is known that the natural polarity of teeth is negative. Positively charged particles and microbes adhere to the surface of the teeth, forming a plaque, and the beginning of the digestion process in the oral cavity leads to the formation of tartar. Over the years, a person changes metabolism and the condition of teeth and gums.

 When using a conventional toothbrush, it is partially possible to remove plaque from the surfaces accessible to the bristles of the brush. But the interdental space retains plaque and tartar. Which leads to caries, bleeding gums, tooth mobility, inflammatory processes in the oral cavity and causes a general deterioration of the body.

 Known toothbrush containing a handle, a head with bristles, a constant current source (RF patent 2129826, A 46 V 9/04, 1999). The power source is installed in the handle of the brush and is connected to the element that conducts current when wet.

 The use of the well-known brush does not allow to ensure sufficient effectiveness of its preventive and therapeutic effects.

 The technical effect of using the proposed solution is the possibility of a physiotherapeutic effect on the oral cavity by changing, according to a predetermined law, the strength of the electric current in the process of using the brush.

 Also, the effect of using the proposed solution is a higher efficiency of preventive and therapeutic actions, expressed in the possibility of protecting the teeth from caries, prevention and treatment of periodontal disease, removal of inflammatory processes in the oral cavity.

 The indicated effect is achieved as follows.

 The toothbrush contains a handle, a head with bristles, an electric current source connected by a positive pole to a conductive element located on the handle, and a negative one to a conductive element located in the bristle area. According to the invention, the current source is made in the form of an electrolytic capacitor installed with the possibility of recharging it from an external current source.

 In this case, the brush can be equipped with a current regulator and / or indicator LED, and an external current source can be made in the form of a network adapter or battery.

 Due to the fact that the brush is equipped with two conductive elements, one of which is electrically connected through the conductor to the positive pole of the current storage element and placed on the handle, and the second is electrically connected through the conductor to the negative pole of the storage element and is located in the area of the bristles, when water enters the bristle closes an electrical circuit. In the process of using the brush, the user's hand is in contact with the conductive element located on the brush handle and connected to the positive pole of the electrolytic capacitor of the power source. At the same time, a negative charge forms on the bristles of the brush. Positively charged particles of plaque on the teeth and tartar are attracted to the bristles of the brush, cleaning the surface of the teeth and oral cavity.

 Due to the fact that the brush is equipped with a storage element, it is possible at the beginning of its use to create the maximum initial charge, which provides a given current strength, followed by its gradual decrease (exponential decrease in current strength) during its use.

 Due to the fact that the brush is equipped with an indicator LED, it is possible to visually control the current strength by the brightness of the indicator, which is also an active current limiter.

 One example of execution is a brush with a removable nozzle covering the handle. A storage element is mounted in the handle, a conductive element is placed on its surface, and the conductor is insulated, removed from the nozzle and placed along the handle. Thanks to this embodiment, a standard toothbrush can be used in the construction. In this case, during operation, it is possible to replace the standard brush with a new one with continued use of the nozzle.

 Figure 1-4 shows a diagram of the claimed device.

 The toothbrush contains a handle 1, a head 2 with a bristle 3 and a storage element 4 DC. The brush is equipped with two conductive elements. The first conductive element 5 through the conductor is electrically connected to the positive pole of the current storage element 4 and is placed on the handle 1. The second element 6 is electrically connected through the conductor to the negative pole of the storage element 4 and is located in the area of the bristles 3.

 In addition, the brush can be equipped with a current regulator 7 and an LED 8 connected to the negative pole of the storage element 4.

 Toothbrush works as follows.

 Before using the brush, the charger is connected to the brush storage element to recharge it. After that, the LED indicator lights up, indicating the charging of the storage element. The current regulator is set to the desired position (in accordance with the recommendations of the dentist). When using a toothbrush, the magnitude of the electric current gradually decreases from maximum to minimum and causes during the procedure a corresponding effect on the oral cavity.

 And in the absence of current in the circuit, the brush can be used without a galvanic effect, acting as a regular toothbrush.

 The process that occurs in the oral cavity is based on a galvanic effect that ensures the movement of positively charged particles located on the teeth and gums towards negatively charged bristles of the brush. Thus, the removal of pathogenic particles from the oral cavity.

 Using the proposed solution allows us to provide the necessary physiotherapeutic effect, which consists in the action of a current of a certain magnitude, which varies during the cleaning process according to a predetermined law depending on the patient’s oral cavity, and ensures reduction of tooth hypersensitivity, strengthening of the gums, teeth whitening, prevention and termination of the carious process, and periodontitis.
