The invention relates to medical technology, namely, devices for reflexotherapy.

The purpose of the invention is to provide an opportunity to assess the severity of pain.

The drawing shows the block diagram of the device.

The device contains active 1 and indifferent 2 electrodes connected to differential amplifier 3, filter 4, pulse shaping unit 5, connected to signal control unit 6 and frequency-voltage converter to converter 7, which is connected to recording unit 8.

Us.troystvo works as follows.

There are points for auriculodiagnosis, the electrophysiological state of which depends on the activity of a certain organ or part of the body. The active electrode 1 is inserted into such an informative point of the auricle, the indifferent electrode 2 is outside the point. At the moment of entering the active electrode 1, action potentials are removed from this point, which are individual electrical impulses. And the higher the pain felt by the patient, the higher the frequency of the impulses. These pulses are amplified by amplifier 3, filtered from interference by filter 4 and fed to a block.

5 pulse generator, for example, consisting of a Schmitt trigger with an adjustable trigger threshold and a pending multivibrator. Adjusting the threshold for triggering the trigger, achieve informative impulses with the subsequent formation of them with a waiting multivibrator. Monitoring informative pulses and

0 setting the trigger threshold of the Schmitt trigger is performed by block 6 of the control signal, executed, for example, in the form of a low-frequency amplifier, since the spectrum of the signal lies

5 in the low frequency range, with a sound indicator. At the same time, the position of the active electrode 1 at a point is monitored by a sonic indicator. From the output of the pulse generator unit 5, the signal also enters the frequency converter unit 7 of the voltage, in which a constant voltage is generated, which is proportional to the frequency of the action potentials

5 with acupuncture points. This voltage enters the registration unit 8, which can be performed, for example, in the form of an arrow ni i6opa, recording the severity

Q pain syndrome in arbitrary units.

The proposed device allows to assess the severity of pain, convenient in operation.
