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.

An external electrode device for SCENAR therapy, the so-called "face electrode" (https://scenar.com.ru/produktsiya/vynosnye-elektrody/elektrod-litsevoj.html) located on an insulating base, a rectangular central active electrode with an area of 1.5-2 cm ² , surrounded by a passive electrode. The electrode device is designed to affect small areas of the skin with a complex relief (periorbital areas, wings of the nose, etc.).

It combines with the proposed utility model the use of bipolar electrodes and a design that provides movement or rearrangement of the electrode device during therapy. However, the specified device does not allow the treatment of skin areas, the impact on the central part of which is impractical, for example, around small wounds, burns, nevi (moles) or inflammatory elements. It also does not allow manipulations within the treatment area, for example, anesthesia during an injection or surgical opening of the boil.

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

Such an electrode device provides good contact with the skin and allows you to act on the skin areas, bypassing the areas where the impact is undesirable, which combines it with the proposed utility model.

The small contact area of the electrodes and the need to work with two hands limits its use.

The problem to be solved by the claimed utility model is to increase the efficiency and safety of electrostimulation by preventing exposure to areas where it is undesirable or inappropriate, as well as providing the possibility of additional manipulations within the electrostimulation zone.

The technical result of using the claimed utility model is to provide exposure to the skin with certain injuries, bypassing areas where exposure is impractical or unsafe due to the possibility of infection from the skin surface, as well as the possibility of combining electrical stimulation (anesthesia) with manipulations within the zone electrical stimulation.

The technical result is achieved in that the electrode device containing fixed on an insulated base active and passive electrodes with conductors, one ends of which are connected to the active and passive electrodes, the other ends are connected to a common connector, contains a window in the insulating base, providing access to the inside of the electrostimulation zone, and active and passive electrodes of a round, elliptical or rectangular shape are placed on the specified base coaxially to each other and to the specified window, while the electrodes can be both flat and convex.

Alternatively, the active and / or passive electrode can be made in the form of several elements interconnected by conductors.

Both of these variants of the electrode device can use an insulating base attached to the handle, which provides access to the interior of the electrostimulation zone.

In addition, both of these variants of the electrode device can use active and / or passive electrodes located on the sliding part (s) of the insulating base.

For fixing the electrode device on the patient's body or limbs, it can contain two diametrically located lugs for the belt.

The electrode device, which includes active and / or passive electrodes made on the sliding part of the insulating base, may contain two diametrically located lugs for a belt that provides fixation of the electrode device on the body or limbs of the patient.

Finally, the electrode device may contain an active electrode placed on an insulating base with a window, and a passive electrode of arbitrary shape, including one in the form of a metal plate, a cylinder or self-adhesive, is made separately for installation outside the zone of influence.

The utility model is illustrated by drawings, which show electrode devices:

in fig. 1 - with active and passive rectangular electrodes;

in fig. 2 - with electrodes in the form of 8 convex circular elements;

in fig. 3 - with a base on the handle;

in fig. 4 - with electrodes on the sliding parts of the base;

in fig. 5 - with a base containing two diametrically located belt lugs;

in fig. 6 - with electrodes on the sliding parts of the base with two diametrically located lugs.

SCENAR devices are widely used by doctors of various specialties. Their main features: the use of inductive energy storage for the formation of high-amplitude electrical stimuli, the use of dry electrodes and the movement of electrodes during therapy. Accordingly, SCENAR devices and the like are produced with built-in electrodes made of special steel, and for the convenience of work in various situations, they are equipped with external electrode devices. In the course of therapy, it may be necessary to influence around a certain area, excluding small wounds, burns, inflammatory elements, or nevi, in order to prevent infection from the skin surface. The task also arises - to carry out local anesthesia before and during injections or other manipulations. The use of the proposed electrode device with a window makes it possible to solve these problems.

Several versions of the electrode device are possible.

FIG. 1 shows a variant with active and passive rectangular electrodes. The window is also rectangular with rounded corners, but can be circular or elliptical. To ensure more reliable contact with the skin, one or both electrodes can be convex (for the purpose of the best contact, the prototype electrodes are made spherical).

FIG. 2 shows a variant with electrodes in the form of 8 convex circular elements. Elements can be connected to each other, for example, through one; that is, the active and passive electrodes in this case will consist of four elements each.

FIG. 3 shows an electrode device with a handle that provides visual control of the electrode installation and access to the inside of the electrostimulation zone for manipulations.

For the treatment of skin surfaces with defects of various sizes, an electrode device with one or both electrodes on the sliding parts of the base can be used, which allows you to change the size of the window. Such an embodiment is shown in FIG. 4.

To fix the electrode device on the body or limbs of the patient, the base can contain two diametrically located lugs for the belt (Fig. 5), which frees you from having to hold the electrode device with your hand.

FIG. 6 shows an electrode device with belt lugs on a base that allows the window to be resized.

In some cases, with complex skin relief, it is impossible to ensure an even fit of both electrodes. In this case, in the case of a small area of contact with the skin of one or both electrodes, the patient may experience unpleasant or even painful sensations due to the concentration of the acting current on a small area of contact. To prevent this, separate electrodes are used: an active electrode of one of the types described above is placed on an insulating base, and a passive electrode of an arbitrary shape, for example, in the form of a metal plate, cylinder or self-adhesive, made separately, is installed and fixed outside the affected zone. It is possible to make a passive electrode in the form of a metal cylinder for fixation in the patient's hand. Such a solution, even in the case of insufficient contact with the skin of a part of the surface of the active electrode, prevents unpleasant sensations for the patient, since the other part of the active electrode is in normal contact.

The use of the claimed electrode device is carried out as follows. Its connector is connected to a 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 zones, the impact on which is inappropriate, are in the window of the electrode device. If there are sliding parts, adjust the size of the window so that the electrodes do not touch unwanted skin elements. When processing a limb, it is advisable to fix the electrode device with a belt, which frees the operator's hands.

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

Similarly, an electrode device is used if it is necessary to carry out certain manipulations in the window area.
