The pulse generating circuit comprises a step-up transformer T1, a field effect transistor Q2, resistors R17, R18, R20, R22 and R24, a potentiometer R21, capacitors C8, C9 and C12, voltage-stabilizing tubes D1 and D2, a diode D3, a triode Q3, a light-emitting diode LED2 and a membrane switch SW2.

The drain electrode of the field effect transistor Q2 is connected with a primary pin 8 of the boosting transformer T1, a primary pin 7 of the boosting transformer T1 is connected with one end of a resistor R19 and one end of a capacitor C8, the other end of the resistor R19 is connected with VCC (9V), the other end of the capacitor C8 is grounded, and a primary pin 6 of the boosting transformer T1 is a hollow pin.

One end of the membrane switch SW2 is grounded, and the other end is connected with a 9V power supply.

When a stimulus pulse is required, fet Q2 discharges capacitor C8 through step-up transformer T1, which produces a high voltage pulse on the secondary side of step-up transformer T1. The high voltage pulse (-150V peak) charges capacitor C9 to the reverse breakdown voltage value of zener D1. The potentiometer R21 is used to set the current of the output electrode. When the membrane switch SW2 is closed, the output pulse is a monophasic wave due to the clamping action of the diode D3. When switch SW2 is open, the accumulated charge on coupling capacitor C9 will be discharged through both electrodes after the stimulation pulse is over, thereby nullifying the net charge transferred through the electrodes into the tissue.

The main function of the electrical stimulation output circuit is to control the pulse width, frequency and duration of the output pulse, and generate an output pulse with a pulse width of 10-300 mus and a frequency of 10-100 Hz, specifically referring to fig. 2, which includes an optocoupler device U2 (EL 357N (C) (TA) -G), timers U3, U5, U6 and a numerical control switch U3.

When the digitally controlled switch SW3 is set to the external trigger mode, the duration and the frequency of transmission of the stimulation pulse train are set by an external controller (e.g. a microcontroller of the FNS system) via the optocoupler device U1. When the pulse input of the J1 (anode) is at a high level, the pin 4 of the optocoupler U1 changes to a low level, the collector of the triode Q1 changes to a high level, the pin 4 of the timer U5 is at a high level, and the timer U5 outputs a square wave pulse.
