ELECTRICAL STIMULATOR Russian patent published in 2018 - IPC A61N1/36 

FIELD: medical equipment.

SUBSTANCE: invention relates to medical equipment. Electrostimulator contains a generator connected to the power supply, controlled by the frequency and duration of the control pulses, a transistor switch whose control input is connected to the output of the generator of the control pulses, and stimulating electrodes. Electrostimulator is also equipped with a zener diode, current-limiting and variable resistors. Zener diode is connected between the base of the transistor and the negative terminal of the power supply and together with the current-limiting resistor forms a voltage divider. Power source is designed as a constant voltage source. Emitter of the transistor is connected via a variable resistor to the positive terminal of the power supply. Collector of the transistor through the stimulating electrodes is connected to the minus terminal of the power source.

EFFECT: increase in the efficiency of treatment and convenience in the operation of the electrostimulator due to the automatic maintenance of the selected stimulation regime is achieved.
