Known portable ozone generator “Medozone” for U.S. patent No. 5503808 priority from 27.12.1993, CL IPC B 01 J 19/086, NCI USA 422-186 .08. This device contains a source of oxygen, the pressure regulator and the ozone generator and is suitable mainly for the sterilization of air and surface treatment of various objects. Here we have the unintended effect of ozone-oxygen mixture on staff, working with the device. The known device is not suitable for individual ozone. The reason for this drawback is the fixed capacity of the ozone generator and the speed of the output stream of ozone-oxygen mixture, and the possibility of the presence in the waste ozonotherapy mixture unacceptably large amount of ozone.

Closest to the claimed is a device for U.S. patent No. 6073627 priority from 30.07.98, CL IPC And 61 M 15/02. A device for ozone prototype contains a source of medical oxygen pressure regulator, the ozone generator and the processing chamber (load) with ozone destructor. The processing chamber is hermetically oblige the t zone of the pathological process and inflated ozone-oxygen mixture with a given concentration of ozone. Proven gas mixture is evacuated through an ozone destructor, so that the unused ozone was not included in the workroom. The device is suitable for individual ozone. A disadvantage of the known device is the limitation of functionality. It is intended for external use of gaseous ozone. With its help it is impossible to conduct the full range of therapeutic techniques associated with the intravenous, intramuscular, intraarticular, subcutaneous administration of therapeutic doses of ozone. The reason for this drawback is the inability to obtain a stable low (up to 0.1 l/min) gas flow and the inability to extract from the device of ozone-oxygen mixture a given concentration of a medical syringe.

Modern ozone therapy has a wide range of impacts in its Arsenal a large number of therapeutic techniques that use ozone-oxygen mixture with ozone concentration from a fraction mg/l to tens of mg/l and flow velocity from a fraction l/min to units of l/min, and a variety of ozonation equipment (i.e. consumers of ozone or load). To meet the needs of numerous techniques, medical institutions have to have a number of devices for ozone with the relevant specifications.

This invention has solved the ass is and to ozone therapy with the use of more and more known therapeutic methods in one device.

The technical result for the solution of this task was to expand the functionality of the inventive device for ozone.

This technical result is achieved by the fact that in comparison with the known device for ozone therapy, including medical oxygen pressure regulator, ozone generator and load with ozone destructor, it is new that it further comprises a switch gas flow located between the pressure regulator and the ozone generator, and a three-way valve with optional destructor is connected to a normally open outlet valve, the normally closed output of which is connected to the load.

The difference between the claimed device is that the flow switch allows depending on the applied treatment methods to provide the required flow rate in a wide range, and the three-way valve forms two gas circuit. In the first, including additional destructor, is the establishment of a gas mixture with a given flow rate and ozone concentration. The second circuit serves for draining the prepared gas flow in the load and carrying out medical procedures. This permits the sampling of ozone-oxygen mixture in medical syringes in a controlled way. In the EIT is sustained fashion expand therapeutic possibilities of the proposed installation.

The drawing shows a block diagram of the inventive device for ozone.

A device for ozone includes a source of medical oxygen 1, the pressure regulator 2, the ozone generator 3 and the load 4 with ozone destructor 5. In addition, the device contains a switch of the gas flow 6, located between the pressure regulator and the ozone generator, and a three-way valve 7 with additional ozone destructor 8, is connected to a normally open outlet valve, the normally closed output of which is connected to the load.

In the example implementation of the claimed device, the oxygen source 1 was a container filled with medical oxygen under a pressure of 120 atmospheres. The cylinder was mounted valve and reducer with pressure gauge. The pressure regulator 2 was made in the form of motor spool (see utility model certificate # 26144 authors Usmanov YU.N., Buranov S.N. and others). The ozone generator 3 included the discharge chamber (see patent No. 2184076 class. With 01 13/11 authors Boranova S.N. and others) and a generator of high voltage pulses of microsecond duration (see application No. 2000120967 from 14.08.2000 authors Buranov S.N. and others). Switch of the gas flow 6 - five. He made for the shut-off valve with manual transmission. In the channels of the valves were installed calibrated nakatali diameter of 0.4-1 mm specifies the velocity of the gas stream. The three-way valve 7 is made with manual transmission. He was switched by connecting the load 4 to the normally closed output. When this was done, the output from the device specified ozone-oxygen mixture. Destructors 5,8 performed from the ozone building, filled with activated charcoal brand SKT-3.

The proposed device is as follows. Oxygen is supplied to the gas system of the device from the container through the open valve and reducer, pressure gauge which the pressure is set above the desktop, but less than the maximum allowable. In the process, the gas pressure in the source of oxygen is changed. Therefore, the gas is supplied to the controller 2, which serves to maintain the operating pressure at a given level. Pressure equalization is achieved by automatically changing the flow area of automotive valve. With the increase in inlet pressure, the cross section decreases with decreasing pressure increases. Thus, the inlet pressure switch 6 almost constantly, and oxygen, passing through one of the open nakatala, flows into the discharge chamber at a given speed from 0.1 to 6 l/min To the electrode system of the discharge chamber pulses of high voltage. The pulse frequency was varied from one Hz to several kHz. To ensure reliable inspire the Finance barrier discharge at low frequencies and relatively stable synthesis of ozone was used pre-ionization discharge gap. By changing the pulse frequency and / or velocity of the gas flow, it is possible to regulate the ozone concentration in the mixture is from 0.1 to 100 mg/L. thus, depending on the flow rate setting time of concentration is 0.5-5 minutes So pre-preparation of the mixture as follows. From the camera ozone-oxygen mixture is fed to the three-way valve 7 and through normally open output - optional destructor 8, decreasing the concentration of ozone in the gas mixture to a level below the maximum permissible concentration of 0.1 mg/m³. After establishing a set concentration to a normally closed outlet valve 7 connects the load 4, while the normally open outlet valve 7 is closed and the gas flow is switched to the load. As a result, the consumer is guaranteed to receive a mixture with a given concentration of ozone in a wide range of costs, and the load may be running with the destructor, and with the closed volume (like a syringe)as the intake mixture is carried out from an already established gas stream.

The pathology of the lower limbs carry out irrigation in a plastic bag when the ozone concentration of 3-5 mg/l feed Rate of the gas mixture of 1 l/min. Duration of aeration from 10 to 40 minutes, which is chosen individually. Treatments irrigation are carried out daily or every other day. On the horse is of worn plastic bag (Luggage), which has two holes: 1 - for supplying an ozone-oxygen mixture from the device for ozone and 2 for excess gas in the destructor. The camera tightly secured with a belt. Filling the bag O₃/O₂the mixture at the given concentration to create pressure, and then connects the destructor and is running gassing. This method is applicable for different types of eczema, burns, bedsores, frostbite, etc.

In addition to the flowing irrigation ozone in the plastic camera also implement the following methods:

- autohemotherapy

- intravenous drip

- intramuscular injection

- subcutaneous injection

- intra-articular introduction

- rectal and vaginal insufflation

the use of ozonated water

- balneotherapy

the use of ozonated oil

- lymphotropic

In most cases, ozone therapy is used in combination with other treatment methods.

Thus, the introduction of the device, switch the gas flow and the three-way valve with additional ozone destructor significantly extend the functionality of the inventive device for ozone.
