The invention relates to medicine, namely to ophthalmology for the treatment of atrophy of the optic nerve, and can also be used in the treatment of vascular disease, neuritis, neurosis, inflammation and injuries.

A device for phonophoresis, to the holder with evenly placed around the perimeter of the solenoids, with parallel axes with L-shaped lugs, short sections which are oriented to the center. Coils with cores create a wave traveling magnetic field that can be used in the treatment of ophthalmologic diseases [1]

However, the traveling wave magnetic field created with the help of this device, spatially highly localized, there is no synchronization with the pulsing of the blood flow and it is impossible to treat diseases of the optic tract.

Known magnetic stimulator that contains a source of alternating magnetic field measurement system pulsations of blood flow and its associated synchronization unit. This magnetic stimulator can also be used for the treatment of diseases of the optic tract alternating magnetic field [2]

However, with this magnetic stimulator is impossible to create a traveling wave magnetic field, there is no photostimulator for initial excitation of the optic tract, besides, it is possible to carry out only the frequency of the sync pulse in the branches of the internal carotid artery, but not the phase, which affects the effectiveness of exposure and the duration of treatment.

The aim of the invention is to increase efficiency is high tract.

This is achieved by the fact that the proposed stimulator contains a number of electromagnets, each of which has a solenoidal winding placed in her ferromagnetic core is U-shaped or cylindrical shape, photostimulator containing a pulsed light source, a set of replacement filters and polarizing filter, plethysmograph with the probe pulse, the synchronization unit power and phase shaper, and an output plethysmograph connected to the synchronization unit and the power output of the synchronization unit and the power supply is connected to the input of the phase shaper and to the output of the phase shaper connected solenoidal windings of the electromagnets and photostimulator.

In Fig.1 shows a variant of the electromagnets with a U-shaped core of Fig.2 is the same, with a cylindrical core; Fig.3 photostimulator with a pulsed light source and color filters of Fig.4 a variant of the co-location of the electromagnets with a cylindrical core, photostimulation and sensor pulse plethysmograph; Fig.5 a variant of the co-location of the electromagnets with a U-shaped core, photostimulation and sensor pulse plethysmograph; Fig. 6 is a structural diagram of a device.

The device soda is historical or U-shaped, photostimulator 5 containing a pulsed light source 6, a set of replacement filters 7, a polarizing filter 8, plethysmograph 9 sensor pulse 10, block 11 sync and power, and phase shaper 12.

The device operates as follows.

On the ear, eyebrow, or the temple of the patient is fixed sensor pulse 10 plethysmograph 9, is placed on the patient's head and fix the chain electromagnets 1 and photostimulator 5, provide an electrical connection of the sensor pulse 10 plethysmograph 9 unit 11 sync and power, and phase shaper 12 solenoidal windings 2 of the electromagnet 1 and photostimulation 5. Orient photostimulator at the centers of the pupils of the eyes. When the power unit 11 sync and power generates the synchronization signal based on plethysmogram from plethysmograph 9. The synchronization signal corresponding to the systole in the branches of the internal carotid artery, enters the phase shaper 12, which runs the electromagnets 1 and synchronously with the passage of the maximum current through the solenoid winding 2 of the electromagnet 1, placed on the front of the patient's head, starts photostimulator 5. When this is the start of a wave traveling magnetic field should be neo is defamiliarization "spike" of the excitation signal, arising in the retina and, therefore, the optic tract during irradiation of the retina light flux after actuation of photostimulation 5. In systems of lamp type traveling wave when the phase velocity of the traveling wave electric field exceeds the speed of the electrons is provided by the acceleration of electrons. Due to the fact that "spike" is always accompanied by the transfer of ions across the membranes of axons and along them, the effect of increasing the rate of transfer of ions will occur in our case, accompanied by increase of speed "spike", i.e. provodimosti optic tract.

When using the traveling wave magnetic field in the space occupied by the optic tract, there is an induced electric field, the wave velocity equals the speed of the wave traveling magnetic field. In this regard, the induced electric field plays the role of accelerator ion transfer in the area of the optic tract.

While intensifying the rate of transfer of oxygen and other components that accelerate the metabolism in the area of the retina, optic tract, optic analyzers and brain in General. This process intensified in conditions of resonance excitation wave running is authorized artery.

When the induced electric field intensifying also Antero - and retrograde transfers of substances along the optic tract, which is always accompanied by adequate stimulation of the optic tract.

Important is the fact that different speeds of change of the magnetic induction on the front and rear edges of the pulse (pulse current in the solenoid windings 2 of the electromagnet 1) each of the electromagnets 1. In this case, if the leading edge generates the commanded direction of the electric field strength, the rear edge of the pulse magnetic field generates a counter direction of the electric field strength. If the first case is provided, for example, the increase in the rate of transport of ions, adequate normal "spike", in the second case, the observed inhibition of ion transfer.

In this regard, the important is the selection of the ratio of the speed of rise of the magnetic field on the front and rear fronts. In the case when one of the fronts, which determines both the magnitude and direction of the induced electric field, increases the speed of transport of ions, it must have a larger slope. Thus, the pulse magnetic induction must b is provided by the fact color wavelength range, which patient is insensitive, i.e., provides the activation of photoreceptors corresponding to the range. Using a polarizing filter 8 provides, first of all, the luminous flux, irradiating the retina, and, in addition, can change the polarization of the light beam. Thus the value of the luminous flux should be sufficient for initiation of a "spike".

Since the initiation of the "spike" for his coming in the visual analyzers take a while (0,03-0,05 C), the lifetime of traveling magnetic fields should be at least. Normal value lability of the optic tract is 30-40 Hz. Obviously during systole (0,1) can be formed 3-4 flash photostimulator 5 and respectively during the same time (0.1 s) must be a traveling wave magnetic field, as provided by block 11 sync and power and phase shaper 12.

Was conducted the necessary research to optimize the proposed device. The combination of these types of stimulation in the proposed phase synchronization stimulating effects (traveling wave magnetic field and pulsed Svyaznoy MAGNETIC STIMULATOR, contains a source of alternating magnetic field measurement system pulsations of blood flow and the associated synchronization unit, wherein, with the aim of increasing efficiency by combined magnetic and light effects, it has a headband, photostimulation that includes a pulsed light source, a set of replacement filters and polarizing filter, and a phase shaper, with a source of alternating magnetic field is made in the form of a number of distributed according to the headband electromagnets formed by each solenoid coil and a ferromagnetic core, a system for measuring the pulsation of the blood in the form of heart rate connected with plethysmographs, the output of which is connected with the synchronization unit, its output to the input of the phase shaper, the output of which is connected to the solenoid winding of the electromagnet and photostimulator.
