Such an electrode device is not suitable for treatment using an electro-stimulating effect, since it does not provide the necessary constancy of the area of contact contact with the skin surface.

In the author's certificate of the USSR No. 730346, MPK2 А61В 5/05, publ. 1976, a sensor for measuring bioelectric quantities is described, which is essentially an electrode device and contains two coaxial electrodes located in a housing made of insulating material, the housing is equipped with a support platform with a diameter of 25 ... 35 mm, in the center of which end surfaces of the electrodes are located, wherein the outer diameter of the outer electrode is 2 ... 6 mm. Such an electrode device is not very effective when used for electrical stimulation due to the instability of the area of contact with the skin. In addition, this design of the electrode device does not imply the possibility of replacing the electrodes.

Electrode stimulation device used in the COSMODIC electronic neuroadaptive stimulator (see the description of the patent of the Russian Federation No. 2244574, IPC7 A61N 1/04, A61N 1/36, publ. 2005, Fig. 8, claim 10 of the claims) comprises a housing of electrical insulating material and external passive and internal active electrodes coaxially placed on the end and / or side surfaces of the housing, connected through the lead wires to the outputs of the electro-adaptive stimulator. Such an electrode device does not involve replacing the electrodes.

The electrode device for electrical stimulation of the neuromuscular apparatus, protected by the patent of the Russian Federation No. 2124344, MPK6 A61H 39/00, A61B 5/05, publ. 1999, intended for restorative treatment in case of traumatic injuries in conditions of impaired innervation, contains a fixed electrode made in the form of an electrically 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. By attaching the electrode device to the operator’s hand, palpation control is provided.

the effectiveness of electrical stimulation. The disadvantage of such an electrode device is that it is unsuitable for use with electro-adaptive stimulators due to the lack of fixing the distance between the passive and active electrodes.

In the published application for the grant of a patent of the Russian Federation No. 96124755/14, IPC6 A61B 5/00, publ. 1999, an electroencephalographic electrode is described comprising contact elements made in the form of electrically conductive pins with rounded contact surfaces and fixed to an electrically conductive base equipped with a lead-out conductor. The contact elements are made elastic, and the electrically conductive base is made in the form of an elastic membrane, while the diameter of the contact elements is 0.1-0.2 mm, and the distance between their axes is 1.0-1.5 mm. The implementation of the contact elements in the form of electrically conductive spikes provides reliable contact with the skin even in the presence of hair. The described electrode is structurally complex and therefore has limited use. In addition, in such an electrode device, it is impossible to change the number of electrodes and their relative position.

Patent of the Russian Federation No. 2071271, IPC6 AB 5/04, publ. 1997, a fast-mounted electrode, Blatova IV, is protected, containing a matrix in a dielectric casing and characterized in that the electrode further comprises at least one hair extender formed by the outer walls of two shoulders located relative to each other under a sharp or straight angle. The matrix is located inside the corner formed by the shoulders. The walls of the flanges, facing the inside of the corner, have a lower height compared to the outer walls. The disadvantage of such an electrode is structural complexity.

The electrode device for puncture electrotherapy, protected by the patent of the Russian Federation No. 2202381, IPC7 A61N 1/18, A61H 39/00, publ. 2003. This electrode device contains indifferent and active electrodes. A current-carrying wire with a plug to which an indifferent lead electrode is connected is soldered to the screen of the flexible cable. The cable is branched into 2-5 electric wires with plugs to which 2-5 round electrodes are connected. The indifferent electrode is made of lead, the active electrodes are made of steel. The disadvantages of the prototype are - the impossibility of electrotherapeutic effects on extended pathological zones, the impossibility of selective effects on the zones under one electrode with the simultaneous exclusion of effects on the zones under other electrodes, the lack of fixation of a given distance between active and indifferent electrodes, the excessive locality of the electrotherapeutic effect.

From the description of the patent of the Russian Federation No. 2262957, IPC7 A61N 1/04, 1/36, publ. 2005, it is known an electrode device containing a connector for connecting an electro-adaptive stimulator, lead wires and electrodes,

an elastic substrate with contact slots for connecting electrodes fixed to it, each contact of the connector for connecting an electro-adaptive stimulator with a current-conducting conductor is connected to its corresponding contact socket, and the electrodes and contact sockets for connecting them are located on different sides of the elastic substrate, with each electrode connected to the corresponding contact socket with a push-button connection (see paragraphs 11 ... 15 of the claims, FIGS. 10, 11). This electrode device is adopted as a prototype. Compared with others with other electrode devices, it differs in that it allows you to change the configuration of the zone of electrical stimulation. The disadvantage is the operational unreliability of the push-button connection of the electrode to the electrode socket.

The technical result from the use of the utility model is to increase the operational reliability of the electrode device and expand the functionality of the electrode device.

The specified technical result is achieved in that the electrode device for electrical stimulation, comprising an insulating casing with holes for electrodes and removable electrodes, further comprises a printed circuit board in which an electrode rod is fixed under solder for each removable electrode, fastened with a threaded connection to the electrode holder, made in the form of a washer , in the axial hole of which, on the opposite side of the thread, a magnet is pressed in to connect to the electrode rod, and the removable electrode is made as fericheskogo segment is pressed into a flat surface in the blind axial bore magnet, wherein the printed circuit board with the soldered electrode rod and a removable electrode are placed on opposite sides of the electrically insulating body and pressed into an electrode holder and a removable electrode adjoin the magnets with opposite poles. The removable electrode is made of silver, and the magnet pressed into it is oriented outward by the south pole. The removable electrode is made of gold, and the magnet pressed into it is oriented outward by the north pole. The electrode holder on the opposite side of the thread for connection with the electrode rod has an end protrusion for fixing in an insulating casing.

The claimed electrode device (figure 1) contains an insulating body 1 with holes for the electrodes, removable electrodes 2, a printed circuit board 3, in the contact area 4 of which, for each removable electrode 2, by soldering 5, the rod of the electrode 6 with a thread on the other end is fixed, and the electrode holder 7, made in the form of a nut-washer with a magnet 8 pressed on from the thread for fastening to the electrode rod 6. The electrode holder 7 is screwed to the electrode rod 6. A removable electrode 2 is made in the form of Segment-parameter, which on a flat surface in a blind axial hole 9 press-fitted magnet, adequate magnet 8 is pressed into the electrode holder 7. As the electrically insulating body 1 the inventive electrode structure may be electrostimulator body to which the electrode device is intended. The printed circuit board 3 can be mounted on the insulating casing 1 using fasteners (not shown in the drawings). The holder of the electrode 7 for fixing in the hole in the insulating casing for the electrode may have an end protrusion, and a removable electrode 2 is recessed on a flat surface under the end of the holder of the electrode 7. Magnets 8 and 9 are oriented in the mounting holes so that when installing the removable electrode 2 at the end the electrode holder 7, they were in contact with opposite poles.

Compared with the prototype, the claimed electrode device is characterized by higher operational reliability, since the adhesion force of magnets 8, 9 is constant without time limitation, and the reliability of the electrical contact of the soldered and threaded connection is higher than the push-button. In addition, the claimed electrode device has wider functionality, since the fastening of the removable electrode 2 with the electrode holder 7 magnets allows

additionally carry out magnetotherapy. Under the influence of a magnet, blood is polarized, ions repel from the magnet and accelerate their movement. Iron, under the influence of a magnet, also moves much faster, and polarity is transmitted to cell membranes, the throughput of which increases, especially for potassium and sodium. When using silver electrodes in which the pressed-in magnets are oriented by the north pole to the contact surface of the removable electrode with the body (the south pole outside the blind axial hole), the healing effect of electrical stimulation is increased due to the fact that the magnetic field helps the body in the fight against diseases caused by viruses, bacteria, fungi, as well as in recovery from injuries since. When using gold removable electrodes, in which the pressed-in magnets are oriented by the south pole to the contact surface of the removable electrode with the body (north pole to the outside of the blind axial hole), the efficiency of electrical stimulation is increased due to the fact that the supply of body cells with oxygen and cell regeneration nutrients is improved and the cell pH is normalized and fabrics. The presence of the printed circuit board in the electrode device makes it possible to place the electrode modules 10 with the control device 11 (the control microcontroller) on the printed circuit board (Fig. 2). The electrode module 10 (Fig. 3) for SCENAR-therapy may contain an electrode holder 7 mounted on the contact area 5 of the printed circuit board 1, an electrode module microcontroller 13, a key stage 14 with a two-section inductor and two electronic switches 15 and 16, the control inputs of which connected to the microcontroller 13. The electrode modules 10 are interconnected by communication lines 12, each electrode module 10 is connected to four spatially surrounding it on a printed circuit board. Each communication line 12 contains a two-wire P / I interface for transmitting information data commands, an address relay bus A, an impact signal C / V bus, and power U and 0 buses, while in the electrode module 10 there are elements for connecting to a two-wire P interface / With the transmission of commands and information data are connected to each other and to the first port of the microcontroller 13, the elements for connecting to the bus A address relay rails are connected each to a separate input of the microcontroller 13, the elements for connecting to the power buses “U” and “0” are connected to each other the other and the corresponding power terminals of the microcontroller 13 and the key stage 14, the signal input of the second electronic key 16 is connected to the power bus "0". An example implementation of the key stage 14 with a two-section inductor and electronic keys 15 and 16 on the PVT322A microelectronic relay is shown in Fig. 4. When applying a control signal to the input of the electronic key 15, the removable electrode 4 mounted on the electrode holder 7, soldered into the contact pad 5, is turned on in the "active electrode" mode. When a control signal is supplied to the input of the electronic key 16, the corresponding removable electrode 4 is turned on

"Passive electrode." In the absence of control signals at the inputs of electronic keys 15 and 16, the corresponding removable electrode 5 is excluded from the electrical stimulating effect.

Since with such a connection scheme each key stage 14 is connected to only one electrode of the electrode device, a change in the number of electrodes included in the “active electrode” mode does not affect the parameters of the electrostimulating signal. The effectiveness of magnetotherapy does not depend on the modes of inclusion of the electrodes.

In the claimed electrode device, permanent neodymium-iron-boron (NdFeB) magnets with a diameter of 3 mm and a thickness of 1 mm can be used. The rod and electrode holder can be made of silver plated brass. The diameter of the removable electrode is 5 ... 8 mm, the thickness is 2 ... 3 mm.
