[0049] A second aspect of the present embodiment provides a working method of an electrical stimulation therapeutic device, using the electrical stimulation therapeutic device, comprising the following steps:

[0050] Step 1: After the generator is worn on the affected part of the user, the control terminal sets the working mode of the generator;

[0051] Step 2: The generator generates a corresponding electrical stimulation signal according to the set working mode, and the electrical stimulation signal is adjusted to a constant current signal and then output; during the process of the electrical stimulation signal being output, the generator performs automatic feedback adjustment to adjust the output electrical stimulation signal.

[0052] Specifically:

[0053] Ⅰ. Set the generator's operating mode through the following sub-steps:

[0054] Step Sm-1: Using the display screen on the handheld control terminal, the human-computer interaction module receives or reads user information;

[0055] Step Sm-2: The control terminal stores pre-stored prescriptions in its database, and the controller matches the user information with the pre-stored prescriptions in the database through round-robin checks;

[0056] If a pre-stored prescription is matched, step Sm-3 is directly executed, or the pre-stored prescription is adjusted to generate the current prescription and then step Sm-3 is executed; if a pre-stored prescription is not matched, the current prescription is added and then step Sm-3 is executed;

[0057] Step Sm-3: The controller sends the pre-stored prescription or the current prescription to the processor of the generator through the communication module. The pre-stored prescription or the current prescription includes instruction information corresponding to the working mode to be executed by the generator.

[0058] This working method provides a programmable control process, please refer to Figure 6 to Figure 7When adjusting the pre-stored prescription to generate the current prescription or add the current prescription, the standard module process is used as the basic adjustment unit to adjust the serial number of the standard module process and the six parameters in each standard module process. The six parameters constitute the parameter process of a standard module, including the duration of the rise of the electric stimulation signal strength T1, the maintenance time of the electric stimulation signal strength T2, the decrease time of the electric stimulation signal strength T3, the intermittent time of the electric stimulation signal output T4, the electric stimulation signal strength value Q1 and the electric stimulation signal frequency value F1. The duration of the rise of the electric stimulation signal strength T1 refers to the process time of the waveform current intensity increasing from 0 to the electric stimulation signal strength value Q1, the maintenance time T2 refers to the duration of maintaining the electric stimulation signal strength value Q1, the decrease time T3 refers to the process time of the waveform current decreasing from the electric stimulation signal strength value Q1 to 0, and the intermittent time T4 refers to the current output stop time in this small stage process.

[0059] According to the user's clinical symptoms and treatment conditions, the doctor can set the above six parameters for each standard module process separately during the electrical stimulation treatment; different or same multiple standard module processes can be combined into a large cycle process. In this embodiment, it is limited that the large cycle process contains a maximum of 15 standard module processes.

[0060] II. Adjust the electrical stimulation signal to a constant current signal by the following method:

[0061] When the generator works according to the set working mode, the pulse generator part will generate corresponding positive and negative pulses to the human body, that is, a positive pulse is generated when transistor Q2, transistor Q3, transistor Q10, and transistor Q11 are turned on at the same time, and a negative pulse is generated when transistor Q4, transistor Q5, transistor Q9, and transistor Q12 are turned on at the same time; the pulse current will flow through the current sampling resistor R51 while flowing through the human body, and a weak voltage signal will be generated at both ends of the current sampling resistor R51; then, the unit gain isolation amplifier U6 can amplify the weak voltage signal generated by the current sampling resistor R51 and realize signal isolation, and transmit the detection signal at the isolation end back to the micro-control chip to solve the problem of sampling without common ground; since the output form of the isolation amplifier U6 is differential output, the 6th and 7th pins of the isolation amplifier U6 need to be connected to the analog-to-digital converter ADC of the micro-control chip, and the analog-to-digital converter ADC needs to be configured to the differential sampling mode to complete the sampling of the current.

[0062] After the current sampling is completed, it is processed by the PID algorithm inside the microcontroller chip. The output voltage of the isolation transformer T1 is controlled by controlling the pulse width of the PWM wave from the microcontroller chip to pin 1 of the transistor Q1. The isolation transformer T1 not only plays an isolation role, but also realizes the function of voltage raising. Therefore, by adjusting the output voltage of the isolation transformer T1, the voltage applied to the human body can be dynamically adjusted when the impedance changes, thereby achieving the purpose of constant current.

[0063] III. Automatic feedback adjustment is performed through the following sub-steps:

[0064] Step Sk-1: Please refer to Figure 8 When the generator outputs an electrical stimulation signal, the user's body will produce muscle tremors and contractions due to the stimulation. The muscle tremor detection unit collects the user's muscle state information in real time and sends the muscle state information to the processor;

[0065] Step Sk-2: the processor extracts muscle shaking characteristic data according to the muscle state information, and then performs comparative analysis on the muscle shaking characteristic data to obtain a comparative analysis result;

[0066] Step Sk-3: The processor makes corresponding adjustments to the linkage signal generating module according to the results of the comparison and analysis.

[0067] In step Sk-1, the acceleration sensor in the muscle shaking detection unit obtains the change of muscle posture by detecting the acceleration in the three directions of x, y, and z; in step Sk-2, the processor will first process the collected acceleration data, including using fast Fourier transform (FFT) to analyze the frequency component, using threshold detection to identify shaking events, extracting the characteristics of muscle shaking by processing the frequency, amplitude, and duration of the shaking, and using algorithms to distinguish muscle shaking from other movements, and finally extracting muscle shaking feature data, which includes shaking frequency and amplitude. The muscle state information collected by the muscle shaking detection unit and the results of the comparative analysis obtained by the processor are all saved by the automatic memory storage unit as a reference benchmark for the patient's tolerance, and are used to generate or update preset thresholds and spasm state feature intervals.

[0068] In step Sk-3, the results of the comparative analysis include exceeding the preset threshold and falling into the spasm state characteristic interval, and exceeding the preset threshold includes exceeding the upper threshold and exceeding the lower threshold. When the result of the comparative analysis is exceeding the upper threshold, the signal generation module reduces the intensity of the electrical stimulation signal; when the result of the comparative analysis is exceeding the lower threshold, the signal generation module increases the intensity of the electrical stimulation signal; when the result of the comparative analysis is falling into the spasm state characteristic interval, the signal generation module stops outputting the electrical stimulation signal, and the processor drives an alarm (the alarm form is an indicator light alarm or a display screen alarm, etc.).

[0069] In summary, the electrical stimulation therapeutic device and its working method provided in this embodiment have the following advantages: First, through the constant current control module and its work, constant current control of the electrical stimulation signal can be achieved, so that the output current will not change suddenly, thereby effectively avoiding problems such as electric burns and instantaneous electric shock; second, through the program logic setting module and its work, the working mode of the generator can be flexibly set according to the user's situation, that is, a personalized treatment plan is achieved, which helps to maximize the effect of the electrical stimulation therapeutic device; third, through the feedback adjustment module and its work, the muscle state information of the user during use can be detected in real time, and feedback adjustment can be automatically made according to the muscle state information, thereby effectively ensuring the treatment effect and improving comfort.
