Description

The utility model relates to medical equipment, namely, to electrode devices for electric impact and can be used in SCENAR-therapy and other methods of electrotherapy.

There are known electrode devices for SCENAR devices and similar ones.

The useful model of the electrode device RU 55290, published on 08/10/2006, contains a housing, electrode holders made of an electrically conductive material with rigidly mounted spherical active and passive electrodes isolated from each other on them, mounted in the end of the tubular housing, and the lead wires are supplied from the other end housing. The electrode device is designed to act on small areas of the skin with a complex relief (periorbital areas, wings of the nose, etc.) and allows exposure with a different inclination of the body of the electrode device, while the contact area of the electrodes with the skin surface does not change due to the spherical shape of the electrodes ... This improves the effectiveness of the treatment of certain diseases and disorders.

With the proposed utility model, the specified electrode device combines the use of spherical elements as contact elements. However, it provides only a small area of contact with the skin at a fixed distance between the electrodes and does not allow simultaneous exposure to the entire electrostimulation zone with a complex relief.

The utility model of the electrode device RU 79786, published on January 20, 2009, is taken as a prototype. Each of the two identical (active and passive) electrodes is made in the form of a sphere with a radius of 5 to 15 mm with a radially extending rod connected by a thread with connectors pressed into a tubular insulated body, and the current-carrying conductors of the active and passive electrodes are connected at one end to the connectors, at the other ends soldered to the common connector.

Such an electrode device provides good contact with the skin due to the use of spherical elements and makes it possible to act on skin zones with different relief, which unites it with the proposed utility model. Compared with the previous one, this electrode device allows processing at an arbitrary distance between the electrodes, but due to the small contact area, it cannot provide a simultaneous effect on the entire electrostimulation zone. In addition, it requires two-handed operation, which limits its use.

The problem to be solved by the claimed utility model is to increase the convenience and efficiency of electrostimulation by ensuring maximum coverage of the electrostimulation zone with complex relief.

The technical result of using the claimed utility model is to adapt the size and shape of the electrodes for a specific area of electrical stimulation with a complex relief.

The technical result is achieved by the fact that the active and / or passive electrodes consist of mechanically unconnected magnetic spheres with a radius of 3 to 10 mm with a biologically neutral coating, the electrical connection between the spheres of the active and passive electrodes is provided by magnetic attraction forces, and the configuration and dimensions of these the electrodes are set by the relief of the skin and the number of magnetic spheres connected to each of these electrodes. In this case, one or both electrodes are dry.

The utility model is illustrated by drawings, which show:

in fig. 1 - two arbitrary configurations of electrodes;

in fig. 2 - cable with crocodile clips and magnetic spheres;

in fig. 3 - an adaptive electrode device covering the phalanges of the fingers.

SCENAR devices are widely used by doctors of various specialties and are used in the treatment of a wide range of diseases, including local manifestations. Therefore, SCENAR devices and the like for the convenience of work, in addition to the main electrodes built into the body, are equipped with external electrode devices for influencing specific parts of the body. This, for example, the rectal-vaginal electrode device RU 41420, published on October 27, 2004, as well as the double ophthalmic electrode "Glasses" (https://scenar.com.ru/produktsiya/vynosnye-elektrody/elektrod-dvojnoj-oftalmologicheskie-ochki. htmn. These electrode devices have a rather highly specialized purpose. And the impact, for example, on the phalanges of the fingers around the entire circumference is quite difficult to organize, especially taking into account the wide range of their sizes in people of different ages and sex. SCENAR-therapy allows the use of not only dry metal electrodes, but also, for example, self-adhesive gel electrodes, which, among other things, solve the problem of fixing electrodes on arbitrary areas of the skin surface.At the same time, gel electrodes, due to maceration of the upper layers of the skin, significantly reduce the amplitude and variability of stimuli, which can reduce the effectiveness of exposure, in particular, "high-frequency" massage [Ya.Z. Grinberg, "About one effect of SCENAR-influence. Izves tia TRTU No. 6, 2004, - S. 100-105. "; Ya.Z. Grinberg, “Once again about the features of SCENAR-impact. Izvestia TRTU No. 11, 2006, - S. 144-147 "].

The use of the proposed adaptive electrode device makes it possible to eliminate this problem, while ensuring good adhesion of the electrodes to the skin, and in some cases, their fixation.

Electrodes of the required size and configuration in each case are formed individually from magnetic spheres (balls) with a biologically neutral coating. As such, you can use balls with a diameter of 5 mm from the Neocube kit (Neocube, https://ru.wikipedia.org/wiki/Neokub), which are quite strongly attracted to each other. They can be used to create both volumetric and flat electrodes of arbitrary shape, repeating the shape of complex surfaces. Magnetic forces provide not only reliable contact between the balls of each electrode, but also some adaptation of the shape of the electrode to the skin surface. This makes it possible to fill in the "uncomfortable" for conventional electrodes of the cavity, such as the middle of the palm or to wrap the "rings" phalanxes of the fingers or wrist.

FIG. 1 shows two arbitrary flat configurations of electrodes made with the indicated magnetic balls. It is most reasonable to connect such adaptive electrodes to the electrostimulator using a cable with crocodile clips, which gripped one such magnetic ball, as shown in FIG. 2.

When exposed to horizontal surfaces of the body from top to bottom, additional fixation of the electrodes is not required. In other cases, the clamping of the electrode can be carried out through the dielectric spacer by the doctor or even the patient himself.

In those cases where the electrodes are to have an annular shape (for example, phalanges of fingers or wrists), their fixation can be carried out at the same time, as shown in Fig. 3.

The use of the claimed electrode device is carried out as follows. Its cable is connected to SCENAR device or similar. The device sets the modes in accordance with the methodological instructions (for anesthesia, stimulation of metabolic processes, etc.). The electrode device is applied to the selected area of the skin, while the operator (doctor, nurse) visually monitors that the electrode covers the entire area of the prescribed exposure, adding or removing magnetic balls as necessary. Then the relief-adapted electrodes are fixed. When processing the limbs or phalanges of the fingers, the electrode device is formed in the form of a ring.

Then the energy is set (as a rule, according to the patient's subjective sensations) and the effect is carried out.
