Description

The utility model relates to medical equipment, namely to devices for electrical stimulation, and can be used in SCENAR-therapy to affect various areas of the human skin surface.

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. During the SCENAR-therapy session, as a rule, several zones on the patient’s skin surface are exposed.

From the description of the patent of the Russian Federation No. 2124344, IPC 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 flexible electrically conductive material, and the second layer is made of electrical insulating, elastic material and is equipped with fastening elements to the palm of the operator. The disadvantage is the presence of a movable electrode and its design, requiring its fastening on the operator’s arm, which makes it necessary for the operator to continuously participate in a therapy session.

It is known (see the patent of the Russian Federation No. 2007118, IPC A 6 B 5/04, publ. 1994.02.15) another electrode device containing a dielectric housing and mounted on it working and monitoring electrodes with electrical leads, as well as a cover with a mounting device, worn on top of the case. The disadvantage is the rigid mounting of the electrodes on the body, which significantly reduces the number of zones of the human skin surface available for processing using the specified electrode device.

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 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 (can have a square shape) with an area of 60 ... 80% of the area of the conductive conductor. The specified medical electrode is adopted as a prototype. The disadvantages of the prototype are the complex and expensive to manufacture design, the difficulty of meeting hygienic requirements due to the use of porous materials in the design, low efficiency when used in SCENAR-therapy due to the lack of localization of the exposure area.

The technical result of using the utility model is to increase the efficiency in SCENAR-therapy due to the possibility of localizing the area of influence on the skin surface, reducing the cost of manufacturing and operating the electrode device

The specified technical result is achieved by the fact that in an electrode device containing several electrodes, which are a conductive plate fixed on a base of dielectric material, the base of the electrode has protrusions with holes, due to which the electrodes can be interconnected to obtain an electrode device of the required size and configurations.

The utility model is illustrated by drawings. Figure 1 shows the design of the electrode. An electrode device is assembled from such electrodes by the methods shown in FIG. 2.

In figure 1, 2 numbers indicate:

1 - base

2 - conductive plate

3 - protrusions with holes,

4 - current supply,

5 - rod

6 - a rubber plait.

The claimed electrode device is assembled from the electrodes shown in figure 1. The electrode is a conductive plate 2 mounted on a dielectric base 1. The base of the electrode has projections with holes 3 on both sides. On one side of the conductive plate there is a current lead 4. When

combining two electrodes, the protrusion of one of them falls between the two protrusions of the other. Passing through the holes of these protrusions the rod 5 (for example, a piece of fishing line of the corresponding diameter) as shown in figa, the electrodes connects to each other. Similarly, electrodes are attached to the obtained pair of electrodes until an electrode device of the required length is obtained.

A second method for assembling the electrode device is shown in FIG. For example, two rubber bundles 6 are passed through holes in the protrusions of the bases of the electrodes 3 on one side and the other. As a result of this, an electrode device is formed, convenient, for example, for stimulating the skin surface of the upper and lower extremities.

Using different amounts of electrodes and various ways of connecting them together, electrode devices adapted for a particular patient and specific pathology are obtained.

Due to the simple design of the electrode and the versatility of the electrode device assembled from them, the production and operation costs of the claimed electrode device are reduced, and its application efficiency is increased.

The electrodes are connected via cables through a mechanical or electronic switch to an electrical stimulator. Electrode switching performed by the operator in case of using a mechanical switch or according to a specified program when using an electronic switch allows changing the localization of the affected area to increase the effectiveness of SCENAR-therapy. If an electronic switch is used, the need for continuous operator participation in the therapy session is eliminated and it can serve several patients at the same time. This leads to a decrease in the load on the operator and increase the efficiency of his work.
