Known methods and apparatus physiotherapy, based on the use of alternating electrical currents of high frequency: darsonvalization (frequency 100

500 kHz, a voltage of 20 to 40 kV) and ultrasonograpy (frequency of 22 kHz, a voltage of 4 to 5 kV) (Century, Yasnohorodska. Electrotherapy, M. Medicine, 1987, S. 114 123). Agents of these very close to the technical implementation and indications of the methods, in addition to the high-frequency current are produced in the region of the contact-discharge electrode with skin corona discharge, heat due to the heat and formed in the air, ozone, affecting the skin's surface and penetrating through its pores in the surrounding tissue, as well as a weak ultraviolet radiation and ultrasound due to the oscillatory effect in the tissues. Electricity the hypoxia system of the body and especially on the autonomic nervous system. This extends the capillaries, improves blood and lymph circulation. Under the influence of the heat and the exciting action of corona discharge increases the activity of metabolic processes in tissues, decrease congestion, pain, itching, improves the functional condition of the neuro-vascular system, manifested antispasmodic action. Bactericidal properties of ozone contribute to the rapid removal of inflammation and accelerated tissue regeneration.

The closest is the device for low-frequency magnetotherapy pole-2 (Soloviev, R. Magnetotherapy equipment, Meters Medicine S. 129 132). The apparatus is designed to contact or remote therapeutic effects of low-frequency magnetic field and consists of an electronic unit and a cylindrical inductors, including solenoid type.

The disadvantages of the known apparatus should include a large weight and dimensions, caused, apparently, versatility and wide range of accessories. The device is intended for use only in the physiotherapy room treatment-and-prophylactic establishments and does not allow for treatment at home.

The purpose of this sobretensiones efficiency through integrated use of various physical factors.

The technical result of the invention is expressed in the software using the same device influence the pathological lesions of various etiologies of low-frequency alternating magnetic field and high frequency high voltage producing in turn an additional physical factors: corona discharge, heat, ozone, ultraviolet radiation, ultrasonic treatment. The device involves a separate application of the basic physical factors in case there are any contraindications to their integrated use that may be exercised by the switch.

The invention consists in that in a device for physical therapy, including a source of low frequency alternating current and connected to the inductor solenoid entered Converter low frequency AC to high-voltage high-frequency voltage input connected to the secondary winding of the inductor is a solenoid that is located coaxially and connected in series with the primary winding. In one embodiment, the device in the cavity of the inductor is a solenoid placed elektrorazryadnye element, filled with inert gas, are connected to the armature of the solenoid at its ends provided with plugs, posted with the formation of a cavity filled with an inert gas, and the plug from the side of the working end of the inductor is a solenoid is a plate of translucent material with a low value of electric strength, while in the cavity from the opposite side of the translucent plate installed high-voltage electrode. In the third embodiment, the armature coil of the solenoid is a cylinder of translucent material with a sealed cavity filled with inert gas, and into the cavity from outside of the end of the inductor entered the high-voltage electrode and the wall of the cylinder from the side of the working end of the inductor is a solenoid made with thinning to ensure the occurrence of corona discharge.

In Fig. 1 shows schematically the design and block diagram of the device according to the point 1 of the formula of Fig. 2 a variant of the device according to the point 2 of the formula (the block diagram is identical), and Fig. 3 a variant of the device according to the point 3 of the formula (the block diagram is identical).

The device (Fig. 1) contains a coil-solenoid 1, consisting of the coil formed by the frame 2 with the annular grooves and laid in primary 3 and 4 windings. The windings 3 and 4 is tmasy with good dielectric characteristics and the outside covered with an insulating layer 5. In the cavity 6 of the coil having a threaded, screwed sleeve 7, also made of insulating material, which strengthened neon electric element 8, which can be applied to standard indicators glow discharge (e.g. TN-0.2 or INF-7). Elektrorazryadnye element is focused by a glass cylinder in the direction of the working end of the coil-solenoid 1. Voracova sleeve 7 into the cavity 6 or twisting it, you can choose the size of the air gap 9 between the surface of the dome 10 of the container electrogenerating element 3 and the surface of the body, thereby adjusting the intensity of the corona discharge. The device also has a Converter 11 low-frequency alternating current with frequency 50 Hz high-voltage sinusoidal voltage of a frequency of 22 KHz, adjustable in the range of 1 to 5 kV. The Converter 11 with its input connected to the secondary winding 4. One of the output ends of the inverter 11 is grounded, and the second is connected to the high voltage electrode 12 electrogenerating element 8. In the Converter 11 includes a switch kind of work (not shown), which allows you to maintain separate operation modes of magnetotherapy and ultrasonography by a physician. is lenoid 1, having the main 3 and the additional winding 4, is provided on its ends with caps placed with the formation of the cavity 6 is filled with an inert gas. The plug 13 from the side of the working end of the coil-solenoid 1 is a plate of translucent material, for example, glass with a low value of electric strength as compared with the frame 2, which ensures the occurrence of corona discharge between the outer surface of the stopper 13 and the surface of the body through an air gap 9, the value of which is selected optimal and is in the range of 0.5 to 1 mm. Transparency stub 13 enables visual monitoring of the efficiency of the device by observing through her glow inert gas under high AC voltage to the high voltage electrode 12, mounted in the cavity 6 from the opposite side of the translucent plate 13. As in the previous embodiment, the device is introduced transducer low-frequency AC to high-voltage high-frequency voltage (Fig. 2 is not shown) connected by the entrance to the secondary winding 4 of the coil-solenoid 1, located coaxially and connected in series with the main obladayuthego current in high-voltage high-frequency voltage (Fig. 3 not shown), connected by the entrance to the secondary winding 4 of the coil-solenoid 1, located coaxially and connected in series with the primary winding 3. But it frame 2 coil-solenoid 1 is a cylinder of translucent material with sealed cavity 6 is filled with an inert gas. In the cavity 6 from the side of the non-working end of the inductor 1 is entered the high-voltage electrode 12 and the wall 13 of the container from the side of the working end of the coil-solenoid 1 is made by thinning to ensure the occurrence of corona discharge through an air gap 9. The glow of the gas in the cavity 6 can be observed both working and non-working sides of the coil-solenoid 1 (arrows), which provides the convenience of monitoring the efficiency of the device without separation from his body.

Offered three different versions of the device allow to take into account the capabilities of the manufacturers and the specific conditions of its application.

The advantage of the first variant (Fig. 1) is the ability to select and control the size of the discharge gap in the air gap 9 between electrogenerated element 8 and the surface of the body to select the intensity of the corona reseratrol 12 voltage from the Converter 11. The advantage of this variant is the use of standard neon electrogenerating lamps, eliminating the need for on the manufacturer's production, providing pumping, filling cylinders arresters inert gas and tap.

The second and third options (Fig. 2, 3) focus on companies with a vacuum areas and production that are able to provide fabrication of frameworks 2 coils coil-solenoid 1 immediately in the form of electrogenerating element followed by winding coils 3 and 4. Fixed the size of the discharge gap 9, bounded by the optimal range of 0,5 to 1 mm, eliminates the possibility of adjustment. However, such adjustment is often not necessary under conditions of routine use. Additionally, the choice of mode of corona discharge within certain limits, can be done by changing the value of the high voltage supplied from the Converter 11 to the electrode 12, is introduced into the cavity 6 with inert gas.

The device operates as follows.

Coil-solenoid 1 (Fig. 1) put the working end of the pathogenic lesion or reflexogenic zone. Serves voltage change is TKE low-frequency alternating magnetic field (shown in Fig. 2 and 3 in the form of power lines). Voltage with the additional winding 4 is input to the Converter 11, which converts low-frequency AC to high-voltage high-frequency voltage, adjustable in the range from 1 to 5 kV and a frequency of 22 kHz, used in ultrasonography. The converted voltage is applied to the high voltage electrode 12 electrogenerating element 8, which is in the cavity 6 of the frame 2 coil-solenoid 1. For high-frequency current between the base electrogenerating element 8 and the body of the patient is formed following circuit: ionized due to the glow discharge gas inside the cylinder, the electric capacity of the glass wall and the air layer in the gap 9 between the dome 10 of the container and the surface of the skin, in which the corona discharge occurs. The current passes through the distributed capacity of the patient's body to the ground, which is closed and one of the output ends of the Converter 11. Thanks limiting current action, low-capacity glass wall of the container, the discharge does not reach the intensity at which it could exert a strong irritant effect or cause pain. Changing with the sleeve 7 the magnitude of the gap 9 (when fixed in the particular sensations, to weak spark, providing little irritating, and in some cases, and a slight burn effect, which is especially effective when conducting point reflexology. During the discharge in the gap 9 is formed in small amounts of ozone, which saturates the surface of the fabric, creating a bactericidal effect. In the spectrum of radiation produced by the corona discharge, there is a weak ultraviolet radiation, providing a therapeutic effect. The discharge is accompanied by a release of the processed tissues of heat and generation of them weak ultrasound due to the oscillatory effect. The procedure is performed by labile or stable methods for 5 to 15 min depending on the indications for treatment 5 15 daily or every other day.

The principle of operation of the device according to the options shown in Fig. 2, 3, does not differ from the one described above, except that the intensity of discharge is governed by the choice of the value of high voltage supplied from the Converter 11 to elektrorazryadnye element formed by the frame 2, filled with inert gas.

Thus on the patient's body is the local combined effect with what would be loaded on, ozone, heat, ultraviolet radiation and ultrasound at therapeutic doses, providing effective therapeutic effect is due to the complexity of their application. If necessary, separate application of the magnetic field and factors produced by a high-frequency voltage and the corona discharge device may be a switch of the kind of work that will allow the physician to consider the indications and contraindications in the treatment of specific diseases.
