Description

The utility model relates to medical equipment, namely to devices for electrical stimulation, and can be used in SCENAR-therapy to influence biologically active points in the spinal column.

Currently, SCENAR-therapy is becoming more widespread in the practice of treating diseases of various pathologies. SCENAR is an abbreviation of the concept of self-controlled energy neuroadaptive regulation. A feature of SCENAR-therapy is that the stimulating effect is carried out by an electric signal, the parameters of which are functionally related to the body's response to the stimulating effect. Popularly speaking, in the process of SCENAR-therapy, a dialogue with the controlling systems of the body is conducted in its own language using a physiological impulse.

From the description of the patent of the Russian Federation No. 2124344, IPC6 A 61 H 39/00, A 61 B 5/05, publ. 1999.01.10 known electrode device for electrical stimulation of the neuromuscular apparatus, intended for rehabilitation treatment for traumatic injuries in conditions of impaired innervation. It contains a fixed electrode made in the form of a conductive plate, and a movable electrode. The movable electrode is made of two layers, with one layer made of elastic electrically conductive material, and the second layer of electrically insulating elastic material and equipped with fasteners to the palm of the operator. Palpation control of the effectiveness of electrical stimulation is achieved due to the design of the electrode device and its mounting on the operator’s hand. The disadvantage is the lack of fixing the distance between the electrodes, the small interelectrode capacitance, which does not allow the use of such an electrode device in SCENAR-therapy.

It is known (see patent of the Russian Federation No. 2007118, IPC6 A 61 B 5/04, publ. 1994.02.15) a more universal electrode device containing a dielectric housing and fixed on it working and control electrodes with electrical leads, as well as a cover with a mounting device put on top of the case. The disadvantage is the uncompensated error of the recorded biopotential that occurs when the signal of the monitoring electrode is used for adaptively filtering interference in the measuring channel due to the low correlation of the transition resistance of the contacts of the working and control electrodes with different geometries with the patient’s body when they are pressed against the body.

From the description of the USSR copyright certificate No. 1797899, IPC7 A 61 N 1/04, publ. 1993.02.28 known medical electrode containing a conductive conductor in the form of a strip of porous material, for example, woven in the form of a grid of

silver threads with a diameter of 0.02 ... 0.04 mm, and serving as the base of the electrode applied directly to the patient’s skin. The conductive conductor is rigidly connected to a metal plate for connecting the electrode. A flexible plate of non-toxic plastic or rubber covers, for example, by crimping, a conductive conductor on three sides and is made with holes (may have a square shape) with an area of 60 ... 80% of the area of the conductive conductor. An electrode device containing two such electrodes used in the treatment of analgesic transdermal electrostimulation is adopted as a prototype. The disadvantage of the prototype is the lack of the ability to fix the distance between the electrodes, which does not allow them to be used with the necessary efficiency in SCENAR-therapy.

The utility model is illustrated by drawings. Figure 1 shows a bottom view of the electrode device, figure 2 shows a side view of the design of the electrode device.

In figure 1, 2 numbers indicate:

1 - housing

2 - active electrode,

3 - passive electrode,

4 - electrode holders,

5 - current supply cord, The technical result from the use of a utility model is an increase in efficiency when used in SCENAR-therapy when it affects the region of the spinal column.

The specified technical result is achieved by the fact that in the electrode device containing the housing, active and passive electrodes, current leads and electrode holders, the electrodes are mounted on holders fixed in the housing, with the possibility of moving with fixing the distance between them, the electrode holders are made of electrically conductive material and insulated from each other, and each holder is connected to a current lead.

6 - fixing element,

7 - damping sleeve,

8 - connector for connecting to an electro-adaptive stimulator,

9 - removable handle.

The claimed electrode device (Figs. 1 and 2) comprises a housing 1 made of an electrically insulating material, in which active 2 and passive 3 electrodes and 4 electrode holders are placed. The holders 4 of the electrodes are made of electrically conductive material. The electrodes 2, 3 are mounted on the holders 4 with the ability to move and fix the distance between them. For example, this can be done if available in

the holder 4 of the groove in which the T-shaped electrode 2 moves. Fixing is carried out by the nut 6. The holders 4 of the electrodes are connected through the current leads (current supply cord 5) to the connector 8 for connection to an electro-adaptive stimulator (not shown in the drawings). To prevent breakage of the conductors of the current supply cord 5, the latter is introduced into the housing 1 through the damping sleeve 7. To provide access to the locking elements 6, the housing 1 has a removable handle 9.

The claimed electrode device is intended for SCENAR-therapy when acting on the spine. The contact surface of each electrode is 1.0 ... 8.0 cm ² . When installing the electrode device paravertebrally on the spine, due to physiological differences, it is important to individually select the size of the impact zone and its localization. A characteristic feature of SCENAR-therapy is that the effect is carried out by high-amplitude pulses of short duration with steep fronts. In the process of exposure, the parameters of these pulses (amplitude, duration, frequency of filling) automatically (based on the principles of biological feedback) change depending on the body's response to the effect. When the body’s reaction to the impact is absent, the parameters of the pulses cease to change, and this is a sign of the need to stop the exposure. As a result, the electro-stimulating effect of SCENAR-therapy is precisely dosed, which explains its high efficiency. The lack of localization of the area of influence reduces the effectiveness of treatment due to erosion of interelectrode currents. In the claimed electrode device, the exposure zone is fixed by the boundaries of the contact surface of the passive electrode 3, which helps to increase the effectiveness of SCENAR-therapy.
