[0048] The circuit module also includes a resistor R33, a resistor R34, a transistor Q14, a resistor R36, a resistor R35, a resistor R83, a transistor Q15, a resistor R86, a resistor R84, a transistor Q21, a resistor R85, a resistor R87, a MOS transistor Q20 and a transistor Q22.
[0049] The PB1 pin of the MCU U9 is electrically connected to the first end of the resistor R33 and the first end of the resistor R34, the second end of the resistor R33 is electrically connected to the base of the transistor Q14, the second end of the resistor R34 is electrically connected to the emitter of the transistor and grounded, the collector of the transistor Q14 is electrically connected to the first end of the resistor R82, the second end of the resistor R82 is electrically connected to the pin C2 of the second light emitter of the optocoupler U8, the pin A2 of the second light emitter is electrically connected to the pin VDD_1 of the MCU U9, the pin C2A of the second light receiver of the optocoupler U8 is electrically connected to the first end of the resistor R36 and the first end of the resistor R83, the pin E2 of the second light receiver is electrically connected to the emitter of the transistor Q15 and grounded,

[0051] In this way, the MCU U9 can output the control signal CtrlB and the control signal CtrlA to the circuit module.
[0052] In a preferred embodiment, the METC control circuit board has an impedance measurement chip, which is electrically connected to the detection electrode. When the detection electrode is in contact with the patient's body, the impedance measurement chip measures whether the impedance is within a reasonable range through the detection electrode.
[0053] In a preferred embodiment, the control circuit of the electric shock therapy device further includes a power transformer, which is connected to an external 220V AC power supply and electrically connected to a METC power rectifier board. After the power transformer is connected to an external 220V AC power supply, it reduces the voltage of the external 220V AC power supply, and then rectifies the voltage of the external 220V AC power supply into a low-voltage and high-current (e.g., 45V, 10A) DC power after being rectified by the METC power rectifier board.
[0054] In a preferred embodiment, the control circuit of the electric shock therapy device further includes an isolation output transformer, and the isolation output transformer is electrically connected between the constant current control circuit and the treatment electrode. It should be noted that in this embodiment, the isolation output transformer can be selected as a coupling transformer.
[0055] Since the voltage of the external 220V AC power supply is rectified into a low-voltage and high-current (for example, 45V, 10A) DC power after rectification by the METC power rectifier board, it is still a low-voltage and high-current power at this time. The low-voltage and high-current is output to the isolation output transformer after passing through the constant current control circuit. The low-voltage and high-current (45V, 10A) needs to be converted into a high-voltage and low-current (450V, 1A) through the isolation output transformer.
[0056] In a preferred embodiment, the constant current control circuit includes a resistor R15, a MOS tube Q18 and a transistor Q19, the first end of the resistor R15 is electrically connected to the METC power rectifier board, the second end of the resistor R15 is electrically connected to the gate of the MOS tube Q18, the drain of the MOS tube Q18 and the collector of the transistor Q19, the source of the MOS tube Q18 is electrically connected to the base of the transistor Q19, and the emitter of the transistor Q19 is electrically connected to the isolation output transformer.
[0057] In a preferred embodiment, the isolation output transformer includes a primary winding LM1, a primary winding LM2 and a secondary winding LM3, the first end of the primary winding LM1 is electrically connected to the first end of the primary winding LM2, the second end of the primary winding LM1 is electrically connected to the emitter of the transistor Q17, the second end of the primary winding LM2 is electrically connected to the emitter of the transistor Q22, the emitter of the transistor is electrically connected to the first end of the primary winding LM1, the secondary winding LM3 is distributed close to the primary winding LM1 and the primary winding LM2, and the output electrode is electrically connected to the secondary winding LM3.
[0058] The direct current DC+ reaches the primary winding LM1 and the primary winding LM2 through the constant current circuit composed of Q18 and Q17. When the control signal CtrlB outputs a high level, the transistor Q5 is turned on, and then the transistor Q17 and the MOS tube Q16 are turned on. The primary winding LM1 is grounded through the MOS tube Q16, and a current loop is generated on the primary winding LM1. At the same time, a forward current is induced on the secondary winding LM3 to the output electrode.
[0059] Similarly, when the control signal CtrlA outputs a high level, the transistor Q21 is turned on, followed by the MOS tube Q20 and the transistor Q22, the primary winding LM2 is grounded through the MOS tube Q20, a current loop is generated on the primary winding LM2, the winding directions of the primary winding LM1 and the primary winding LM2 of the isolation output transformer are opposite, and a reverse current is induced on the secondary winding LM3 to the output electrode.
[0060] In a preferred embodiment, the stimulation therapy host further includes a breathing light, which is electrically connected to the METC control circuit board and can light up according to the working state of the stimulation therapy host. Specifically, when the stimulation therapy host is in a normal working state, the breathing light lights up in green, and when the stimulation therapy host is in an abnormal working state, the breathing light lights up in red.
[0061] When the detected impedance measurement value is not within a reasonable range, the MECT control circuit board controls the breathing light to flash red, and at the same time sends the impedance measurement value to the touch screen (the touch screen serves as the host computer) through the communication board. When the detected impedance measurement value is within a reasonable range, the control main board outputs the corresponding control instructions (including frequency, pulse width, number and other information instructions) to the METC control circuit board through the communication board, thereby controlling the METC power rectifier board to complete the corresponding DC conversion, and the breathing light flashes green.
[0062] In a preferred embodiment, the control circuit of the electric shock therapy device also includes a power filter, and the power filter is connected to an external 220V AC power supply and is electrically connected to the power filter. Filtering can be achieved by setting the power filter.
[0063] Working principle:
[0064] The detection electrode is brought into contact with the patient's body. The impedance measurement chip detects whether the impedance is within a reasonable range through the detection electrode. During the patient's treatment, the acquisition circuit board collects the EEG signal according to the detection electrode and sends it to the touch screen for display.
[0065] The control command is input through the touch screen and sent to the communication board. The communication board sends the control command to the METC control circuit board, which then controls the METC control circuit board to output a pulse signal to the MTEC power rectifier board. The METC power rectifier board starts working to rectify the incoming AC power into DC power and output it to the constant current power supply, thereby outputting a pulse width controllable and stable DC+ (450V, 1A).
[0066] The direct current DC+ reaches the primary winding LM1 and the primary winding LM2 through the constant current circuit composed of Q18 and Q17. When the control signal CtrlB outputs a high level, the transistor Q5 is turned on, and then the transistor Q17 and the MOS tube Q16 are turned on. The primary winding LM1 is grounded through the MOS tube Q16, and a current loop is generated on the primary winding LM1. At the same time, a positive current is induced on the secondary winding LM3 to the output electrode to stimulate the patient for treatment.
[0067] Similarly, when the control signal CtrlA outputs a high level, the transistor Q21 is turned on, followed by the MOS tube Q20 and the transistor Q22, the primary winding LM2 is grounded through the MOS tube Q20, a current loop is generated on the primary winding LM2, the winding directions of the primary winding LM1 and the primary winding LM2 of the isolation output transformer are opposite, and a reverse current is induced on the secondary winding LM3 to the output electrode to stimulate the patient for treatment.
