The invention relates to medical equipment, in particular to electron-neurostimulants, and can be used both for the treatment of a number of diseases and for research.

A device is known comprising a pulse generator, the output of which is connected to a pulse amplitude controller, an operating mode switch, active and passive electrodes, a comparator, the output of which is connected to an electronic key, an LED indicator and a resistor divider.

This device is intended only for influencing shark points, the circuit is bulky / spares unwanted side effects on the channel and the body as a whole, contains a large number of control elements and has imperfect electrodes.

The invention is expressed in the fact that in a known device containing a pulse generator, the output of which

passive electrode, and both electrodes are rigidly fixed to the housing. This reduces the distance between the working electrodes to 7-9 mm, which eliminates the undesirable effect of electric current on the human body. The output of the amplifier - comparator is connected to a generator, which is used both in the exposure mode and in the search mode and generates a peak pulse with a varying amplitude and frequency. The frequency of the generator varies from 1 to 100 Hz.

A pulse frequency indicator is included in the generator circuit, which is used as an LED - it is also used as a light stimulus. The switch switches from search mode to stimulation mode.

The device in search mode operates on the principle of finding a point with maximum electrical conductivity. The working body of the device makes it possible to determine the location of the acupuncture point, as well as the auricular point, with accuracy to the millimeter. In stimulation mode, peak-shaped pulses are used. Pulse duration 0.7 ms.

The stimulation affects only the given point necessary for the impact, but in no way the neighboring and not the whole meridian. The amplitude and frequency of the impact of the pulses can be changed on the recommendation of a physician by setting appropriate jumpers.

The proposed device (Fig. 1) consists of a peak pulse generator 1, an amplifier-comparator 2, a pulse frequency controller 3, a pulse amplitude controller 4, a search tuning corrector 5, an electronic key 6, a microassembly 7, an LED 8, a mode switching button 9 operation, power cell 10, electrodes 11, power on toggle switch 12.

The device operates as follows. To use the device in search mode, turn on the toggle switch 12 and press the button 9 (operation mode switching button), the active electrode A is connected to the measuring circuit of the amplifier-comparator. Using electrodes, the proposed area on the skin is examined, the point with maximum electrical conductivity is found, which unbalances the measuring bridge of the amplifier-comparator 2, formed by the elements Ra, RS, RS, the diagonal of which includes the inverting and non-inverting inputs of the element. The unbalance signal from the output of the amplifier through the element R goes to the electronic key 6, which is installed in parallel
