Description

The invention relates to medical technology, mainly to electroacupuncture devices.

The purpose of the invention is to reduce trauma by performing a given mode of exposure.

The drawing shows a diagram of the device.

The electropuncture device contains an active electrode 1, an additional active electrode 2, a boost winding 3, a transformer A and a shock excitation circuit 5, a pulse generator 6, a control unit 7, a solenoid 8, a moving core 9, a low-frequency generator 10, a synchronization unit 11, a stop 12 .

The device works as follows.

The rectangular pulses from the generator 6 act on the circuit 5 of shock excitation, in which high-frequency electromagnets appear.

nitty oscillations. The high frequency voltage rises to 1-3 kV by the boost winding 3, inductively connected to the shock excitation circuit 5, and is applied to the active electrode 1 and the additional active electrode 2. The control unit 7 generates low-frequency pulses modulating the amplitude of the pulses of the pulse generator 6, forming pulse envelope at the output of the device. In addition, low-frequency pulses from the control unit 7 are sent to the synchronization unit 11, which generates synchronization pulses with a predetermined shift, the phases fed to the input of the low-frequency generator 10 associated with the coil of the solenoid 8. The magnetic field of the solenoid 8 controls the movement of the moving core 9, on which strengthened active electrodes 1 and 2; moreover, the minimum distance from the active electrodes 1 and 2 to the biological object is established by means of the stop 12,

the hole in the center of the base of which indicates the stimulation zone.

Depending on the goals of therapy, it is possible to establish various modes of spark or corona discharge by changing the phase between the mechanical movements of the active electrodes 1 and 2 of the modulating pulses of the control unit 7.

So, for example, if the electrodes I and 2 are removed from a biological object at the time of applying a voltage, a spark discharge occurs on them with a pronounced thermal effect. If the voltage is applied to the electrodes 1 and 2, which are sufficiently distant from the biological object, then only corona discharge takes place, the intensity of which varies with the distance of the electrodes 1 and 2 from the biological object during their mechanical oscillations.

In addition, the mode can be changed by changing the maximum distance from electrodes 1 and 2 to the surface of a biological object using stop 12, as well as by varying the amplitude of their oscillations.

In the case when control unit 7 sets the mode of continuous voltage supply to electrodes 1 and 2, low-frequency generator 10 can set any desired frequency of mechanical oscillations of electrodes 1 and 2.

If the stimulation mode is carried out with stationary electrodes 1 and 2, the pulses do not enter the winding of the solenoid 8, and the distance to the biological object is determined only by the stop 12.

The device allows to provide constant quantitative characteristics of the exposure and thereby achieve repeatability of the stimulation conditions and reduce trauma. Automating the procedure for moving the electrodes greatly simplifies the process of therapy and facilitates the working conditions of the medical staff.
