The tube forming the channel for supplying the ozonated solution to the dental tip is immersed at one end in the ozonated solution of the container, and the other, through a membrane-type electromagnetic valve, is connected to the dental tip. An additional tube is made in the device, connected at one end to the compressed air supply channel by means of a tee, and at the other, connected to a membrane valve, which mechanically closes and opens the electric circuit with the power source.

A membrane type electromagnetic valve is connected to the device’s electric circuit, which regulates the supply of ozonated liquid from the tank through the channel for supplying the ozonated solution under the pressure of the air entering the tank.

Description

The utility model relates to the field of dental equipment and can be used in practical dentistry for supplying ozonated solutions to various kinds of dental tips.

One of the criteria for the successful treatment of periodontitis is a thorough mechanical and drug treatment of the carious cavity and root canal during treatment, the most complete elimination of residues of organic matter, bacteria and toxins. The solutions used for these purposes should have bactericidal, anti-inflammatory and antihypoxic properties, should not cause allergic reactions and irritating effects on periodontal tissues.

Recently, widespread use in medicine, and in particular in dentistry, are found in ozonated aqueous solutions, including ozonated aqueous solutions of sodium chloride [RU 2279279 Cl 2005]. For processing, mainly freshly prepared solutions are used,

since the ozonized saline solution is very unstable, and the storage conditions used do not allow to maintain the initial concentration of ozone in the solution used. The need for direct preparation complicates the technology, requires special expensive equipment and strict adherence to safety regulations.

A device for supplying fluid from a container to a dental handpiece is known, in which the liquid in the container, through compressed air entering the tank, is directed along a special line to the dental handpiece [US 6279782, B65D 83/14, 2000].

A disadvantage of the known device is the lack of automatic control of the supplied ozonated solution.

It is known to use a special syringe for supplying ozonated solutions to the carious cavity [RU 2279279 Cl, 2005]. The intake of the ozonized solution of the required concentration with a special syringe is fed directly from the container to the treatment area, which in turn causes inconvenience, since the dental tool cannot be used at this moment.

The basis of this utility model is the solution of the problem of creating a closed system for supplying ozonated solutions during treatment directly to the area of the medical instrument - the dental tip.

The technical result of the utility model is to simplify the design of a closed system for supplying ozonized solutions, as well as providing the possibility of using the supplied ozonized solution directly in a dental instrument during treatment.

The technical result is achieved in that in a device for supplying an ozonized solution to a dental handpiece containing

a container with an ozonated solution, a channel for supplying an ozonated solution to the dental handpiece and a channel for supplying compressed air to a container made of an elastic tube, one end of a hermetically sealed container lowered into the gas atmosphere, and the other end connected through a check valve, pressure gauge, tee and adjustment a valve with a centralized air supply system in the equipment of the dental unit, the channel for supplying the ozonized solution to the dental tip is also made of elast an egg tube, one end immersed in a container of ozonized solution, and the other through a membrane-type electromagnetic valve connected to the dental tip, the device is further provided with a tube, one end connected to the compressed air supply channel via a tee, and the other interfaced with a membrane valve, which mechanically closes and opens the electric circuit with the power source, a membrane-type electromagnetic valve is connected in the electric circuit of the device, which regulates the flow sensing ozonated liquid from the tank through the channel for supplying the ozonated solution under the pressure of the air entering the tank.

Elastic tubes are usually made of polyvinyl chloride.

The applicant has not identified technical solutions that are identical to the claimed utility model, which allows us to conclude that it meets the criterion of "novelty."

The essence of the utility model is illustrated by the figure [Figure 1], which schematically shows a device for supplying an ozonated solution to the dental tip.

The device operates as follows.

The ozonated solution is located in a hermetically sealed container (1), into which two elastic tubes (2, 3) are lowered at one end. One of the tubes (2) forms a channel for supplying the ozonated solution (4) to the dental tip (5) from the container (1). One end of the tube

(2) dipped directly into the ozonated solution (4). The second tube (3) forms a channel for supplying compressed air to the container (1). One end of the tube (3) is in the gas atmosphere (6) of the container (1) above the solution (4). The first tube with the solution entering it (under pressure in the container) is connected to a membrane-type electromagnetic valve (7), through which it is directed to the connecting valve (12) of the dental tip (5). The design of the dental handpiece usually provides for a channel for supplying gas. A connecting valve (12) connects the tube (2) to the gas supply channel in the tip body.

The second tube (3) connects the gas atmosphere above the ozonated solution of the tank through a non-return valve (8) that prevents air from flowing back in, a manometer (9) designed to determine the pressure of the supplied air in the system, a tee (10) and an adjustment valve (11) with the system (16) centralized supply of compressed air in the equipment of the dental unit.

Both channels are made of elastic tubes (2, 3), which are usually made of polyvinyl chloride.

An additional tube (13) is made in the device, connected at one end to a tube (3) forming a compressed air supply channel through a tee (10), and the other is connected to a membrane valve (14), which mechanically closes and opens the electric circuit with a power source (fifteen). A 12V battery can be used as a power source. A membrane type electromagnetic valve (7) is connected in the device’s electric circuit, which regulates the supply of ozonated liquid from the tank through the channel for supplying the ozonated solution under the pressure of the air entering the tank.

To turn on the system, the doctor connects the air supply connector in the system of the centralized compressed air machine, presses the pedal, thereby sending an air pulse through the channel for compressed air supply

air (tube 3) through the control valve (8), tee (9), pressure gauge (10) and non-return valve (11) into the tank (1) for storing the ozonized solution. Using the control valve (8), the necessary pressure of the supplied air is created, which is determined by the pressure gauge (10) and is set depending on the required flow rate of the ozonated solution. Through the tee (9), installed by the control valve, the air flow is also supplied to the membrane valve (14), forming a key in the electric circuit. The air flow has a mechanical effect on the membrane valve, which in turn closes the electric circuit with the power source (15), as a result, the membrane-type electromagnetic valve (7) closes, which accordingly opens the way for the ozonized liquid flow from the tank (1) through the tube (2) ), which is directed to the dental handpiece by the action of air entering the container (1).

Thus, the claimed utility model is a device for supplying the ozonated solution from the container directly to the dental handpiece, without the use of an additional syringe, while ensuring reliable storage of the ozonized solution in a hermetically sealed container. The device is simple to perform, does not require expensive equipment and materials.
