[0079] Step 8: Establish a long-term clinical follow-up and data tracking mechanism to continuously optimize the current parameter preset scheme.

[0080] The specific implementation methods of the above steps are described in detail below:

[0081] The specific implementation method of step 1 is to select the precise screening and clinical enrollment of the patient population. First, through a comprehensive medical evaluation method, select patients aged between 18 and 65 years old with clinical symptoms such as neuralgia, muscle tension, and abnormal meridian function. Patients enrolled in the group must meet the following conditions: patients with neuralgia must be diagnosed by electrophysiological examination and imaging examination, patients with muscle tension must be evaluated by electromyography and clinical symptoms, and patients with meridian blockage must be diagnosed by a combination of traditional Chinese medicine syndrome differentiation and modern medical examination. Exclusion criteria include: patients with severe cardiovascular disease, coagulation dysfunction, immune system disease, and implanted medical devices. Informed consent must be obtained from the patient before enrollment, and approval must be obtained from the Medical Ethics Committee. A comprehensive baseline medical evaluation is required before enrollment, including detailed medical history collection, physical examination, laboratory tests, and imaging examinations.

[0082] The specific implementation method of step 2 is to develop standardized diagnosis and treatment plans and intervention protocols. During the continuous diagnosis and treatment process, electroacupuncture treatment is performed 1 to 2 times a week, and each treatment time is controlled at 30 to 45 minutes. Before treatment, the patient needs to undergo a detailed physical assessment and health status confirmation. The selection of treatment sites is based on traditional Chinese acupuncture and modern medical anatomy, and is precisely located according to the patient's specific symptoms. During the treatment, a multi-needle electroacupuncture device is used, and the depth and angle of the electroacupuncture needle need to be personalized according to different acupuncture points and the patient's constitution. During treatment, the patient's physiological indicators need to be monitored in real time, including heart rate, blood pressure, skin conductivity, and local tissue reactions.

[0083] The specific implementation method of step 3 is to establish a comprehensive and systematic clinical observation record. Doctors need to use standardized clinical assessment tools and scales to objectively and quantitatively evaluate the patient's clinical symptoms under different treatment modes. For the neuralgia mode, the focus is on recording the pain intensity, pain duration and analgesic effect. The muscle relaxation mode focuses on evaluating muscle tension, joint range of motion and muscle pain index. The meridian dredging mode focuses on changes in meridian sensitive points, the state of qi and blood circulation and local tissue microcirculation indicators. The acupoint stimulation mode focuses on observing acupoint sensitivity, nerve reflexes and autonomic nervous system functions. At the same time, record the patient's subjective feelings, physiological and psychological changes before and after treatment. Use visual analog scales, digital pain scores and quality of life assessment scales for multi-dimensional evaluation.

[0084] The specific implementation method of step 4 is to carry out long-term systematic clinical follow-up observation. The follow-up observation period is 3 to 6 months, which is divided into a continuous treatment period and a follow-up observation period. During the continuous treatment period, a detailed medical evaluation is carried out every 2 weeks to record the patient's treatment response and physical changes. During the follow-up observation period, a monthly review is conducted to evaluate the long-term effect and stability of the treatment. The indicators of follow-up observation include: changes in clinical symptoms, recovery of physiological functions, improvement in quality of life, and potential adverse reactions. Establish a special electronic medical record system to ensure the integrity and traceability of the data. Develop personalized follow-up observation plans for patients of different age groups and different types of diseases.

[0085] The specific implementation method of step 5 is to dynamically optimize the precise regulation of current parameters. According to the individual differences and treatment responses of patients, doctors need to make personalized adjustments to the current parameters. The key indicators for adjustment include current frequency, current intensity and pulse width. For patients with neuralgia, the current frequency adjustment range is 2 to 50 Hz, and the intensity is controlled at 1 to 5 mA. The current frequency of the muscle relaxation mode is adjusted to 10 to 30 Hz, and the intensity is controlled at 0.5 to 3 mA. The current frequency range of the meridian dredging mode is 1 to 20 Hz, and the intensity is controlled at 0.3 to 2 mA. The current frequency of the acupoint stimulation mode is adjusted to 5 to 25 Hz, and the intensity is controlled at 0.2 to 1.5 mA. By comparing the patient's symptom improvement, quality of life score and functional recovery, the current parameters are continuously fine-tuned.

[0086] The specific implementation method of step 6 is to conduct multi-dimensional data analysis and clinical evaluation. Doctors need to use statistical methods to conduct a comprehensive analysis of the long-term diagnosis and treatment data of multiple patients. Use statistical methods such as descriptive statistics, variance analysis and regression analysis to evaluate the stability of current parameters and therapeutic effectiveness under different modes. Establish a multi-dimensional data evaluation index system, including symptom relief rate, quality of life improvement index, degree of functional recovery and patient satisfaction. Conduct subgroup analysis on patients of different age groups, genders and disease types to identify the optimal range of action of current parameters and individualized treatment strategies.

[0087] The specific implementation method of step 7 is to write the optimal current parameter scheme into the control chip. Based on the results of clinical data analysis, the verified current parameter scheme is accurately encoded and written into the control chip of the multi-needle electroacupuncture device. The encoding process needs to ensure the accuracy and stability of the parameters, including the specific values ​​of current frequency, intensity and pulse width. In order to ensure the adaptability of the device, a parameter fine-tuning interface is set in the control chip to allow doctors to optimize personalized parameters according to the individual patient's situation. At the same time, a parameter version management mechanism is established to record the detailed information and basis of each parameter adjustment.

[0088] The specific implementation method of step 8 is to establish a continuous clinical follow-up and data tracking mechanism. Build a patient-centered long-term follow-up database to record the patient's treatment process and follow-up. The follow-up period is set at 6 months, 12 months and 24 months. Through regular clinical evaluation and questionnaire surveys, the patient's treatment effect and long-term prognosis are continuously tracked. Establish a multi-center, cross-regional clinical data sharing platform to achieve real-time interaction and analysis of clinical data. At the same time, develop supporting data analysis software that can automatically identify and extract key clinical indicators to provide data support for the continuous optimization of current parameters.

[0089] Specifically, the principle of the present invention is: the multi-needle electroacupuncture device of the present invention is mainly composed of a flexible circuit board, multiple electroacupuncture needles, an electrode assembly, a control chip, a current modulation module and a fixing part. Among them, the flexible circuit board is made of medical-grade materials, can fit the curved surface of the human body, and has multiple needle holes on the surface according to the distribution of acupuncture points. A multi-layer circuit structure is integrated inside the flexible circuit board, including an insulating layer and a conductive layer. An independent electrode assembly is arranged inside each needle hole, including a ring electrode and a through electrode, which can form a closed loop with the electroacupuncture needle. The control chip is electrically connected to multiple current modulation modules through a multi-channel digital signal processing circuit to achieve independent regulation of the current of each needle.

[0090] In response to different treatment needs, the control chip has built-in multiple treatment options such as neuralgia mode, muscle relaxation mode, meridian dredging mode and acupoint stimulation mode. In each mode, the control chip will automatically adjust the corresponding current frequency, current intensity and pulse width parameters. At the same time, the control chip can also interact with external devices and set parameters through the wireless communication interface. Each current modulation module also has real-time parameter monitoring and automatic adjustment functions, and can dynamically adjust the current parameters according to human physiological feedback.

[0091] Long-term clinical research is the key to determining the optimal current parameters. Doctors will select patients with symptoms such as neuralgia, muscle tension, meridian blockage, and acupoint dysfunction for continuous diagnosis and treatment, and record the clinical response under different current parameters. After 3-6 months of systematic follow-up observation and data analysis, the optimal stability and therapeutic effectiveness of current parameters in each treatment mode are determined. These optimal parameter schemes are preset in the multi-mode control module of the control chip, and a long-term follow-up mechanism is established for continuous optimization.

[0092] The following is an example of a specific application scenario of the present invention: A 50-year-old male patient, Mr. Wang, comes to the outpatient clinic of the Department of Neurology of a medical institution for treatment due to recurrent back and leg pain. After a preliminary examination, the doctor diagnoses Mr. Wang with sciatica caused by lumbar disc herniation. The doctor decides to use the multi-needle electroacupuncture device provided by the present invention for treatment.

[0093] First, the doctor conducted a comprehensive baseline assessment of Mr. Wang. Through the collection of medical history, it was found that Mr. Wang had received conservative treatment for lumbar disc herniation 3 years ago, and the symptoms were relieved for a time, but they recurred in the past year, seriously affecting his daily life and work. Physical examination found that Mr. Wang had limited lumbar spine mobility, slightly decreased lower limb muscle strength, and weakened right knee reflex. Imaging examination showed that the L4 / L5 intervertebral disc was significantly bulging, compressing the right sciatic nerve. Laboratory tests showed no obvious abnormalities. Based on the above examination results, the doctor diagnosed Mr. Wang with sciatica caused by lumbar disc herniation.

[0094] After a detailed understanding of Mr. Wang's condition, the doctor decided to use the multi-needle electroacupuncture device provided by the present invention to treat Mr. Wang. First, the doctor selected the "neuralgia mode" as a treatment plan based on the characteristics of Mr. Wang's condition. In this mode, the control chip will automatically adjust the current frequency, current intensity and pulse width parameters of the electroacupuncture stimulation to achieve the purpose of relieving neuralgia.

[0095] The specific operations are as follows:

[0096] 1. Preparation

[0097] The doctor finds the needle holes corresponding to the acupuncture points such as the lumbar spine and the posterior superior iliac spine on the flexible circuit board, and carefully checks the skin around the needle holes with sterile gloves to ensure that there is no damage, inflammation or other abnormalities. Then, the disposable sterile electroacupuncture needles are taken out, inserted into the needle holes one by one, and the depth and angle of the needles are adjusted so that they just touch the patient's skin surface. The needles are selected to be stainless steel needles with a diameter of 0.8 mm and a length of 40 mm.

[0098] Next, the doctor attached the flexible circuit board to Mr. Wang's waist skin, so that the needle was accurately aimed at the target acupuncture point. The circuit board was firmly fixed to the skin surface through fasteners such as Velcro and medical tape to ensure that it would not shift in position. Finally, the doctor connected the control unit to the flexible circuit board through a dedicated electrical connection interface.

[0099] 2. Treatment process

[0100] After the treatment begins, the control chip first sets the parameters of "neuralgia mode" and controls the current output of each needle through a multi-channel digital signal processing circuit. The specific parameters are as follows:

[0101] Current frequency: 15Hz

[0102] Current intensity: 3mA

[0103] Pulse width: 300μs

[0104] The doctor observed that soon after the electroacupuncture stimulation began, Mr. Wang felt a slight soreness and swelling at the acupuncture site, and gradually developed a local redness on the skin. Through real-time monitoring, the doctor found that Mr. Wang's skin conductivity and local temperature had increased, indicating that the treatment current was working and stimulating the relevant nerve endings.

[0105] After 30 minutes of treatment, the doctor observed that Mr. Wang's pain level was significantly reduced and the soreness and swelling in his lower limbs were also relieved. The doctor then adjusted the current parameters to:

[0106] Current frequency: 20Hz

[0107] Current intensity: 4mA

[0108] Pulse width: 400μs

[0109] The treatment continued for 15 minutes. At this time, Mr. Wang reported that the pain had basically disappeared and his lower limbs were more flexible. At the end of the treatment, the doctor checked Mr. Wang's physiological indicators again and found that all indicators had returned to normal levels.

[0110] 3. Efficacy evaluation

[0111] After the treatment, the doctor conducted a detailed evaluation of Mr. Wang's clinical symptoms. The visual analog scale (VAS) was used to evaluate the pain intensity. The VAS score was 7 points before treatment and dropped to 2 points after treatment, and the pain was significantly relieved. At the same time, the numerical pain score (NRS) was used for evaluation. The NRS was 6 points before treatment and dropped to 3 points after treatment. Clinical examination found that Mr. Wang's lower limb muscle strength returned to normal, and the tenderness of the posterior superior iliac spine was also significantly reduced.

[0112] In addition, the doctor also evaluated Mr. Wang's quality of life. Before treatment, due to recurrent back and leg pain, Mr. Wang's quality of life scale (SF-36) score was low, with a total score of 52 points. After treatment, Mr. Wang's overall health condition improved significantly, and the total SF-36 score increased to 72 points.

[0113] Based on the above clinical evaluation indicators, the doctor believes that the treatment effect of the multi-needle electroacupuncture device is good. Mr. Wang's neuralgia symptoms have been significantly relieved, and his physical function and quality of life have been significantly improved. The doctor decided to continue using the device to carry out follow-up treatment for Mr. Wang.

[0114] 4. Follow-up treatment

[0115] In the following treatments, the doctor adjusted the current parameters appropriately according to Mr. Wang's feedback. The specific adjustments are as follows:

[0116] Treatment 1 (2nd time):

[0117] Current frequency: 18Hz

[0118] Current intensity: 3.5mA

[0119] Pulse width: 350μs

[0120] Treatment 2 (3rd time):

[0121] Current frequency: 22Hz

[0122] Current intensity: 4.2mA

[0123] Pulse width: 380μs

[0124] Treatment 3 (4th time):

[0125] Current frequency: 25Hz

[0126] Current intensity: 4.5mA

[0127] Pulse width: 420μs

[0128] By dynamically adjusting the current parameters, the doctor found that Mr. Wang's symptoms continued to improve, with the VAS score stable between 2-3 points and the NRS score controlled at 3-4 points. At the same time, Mr. Wang's lower limb muscle strength and joint mobility gradually returned to normal. The total score of the quality of life scale (SF-36) reached 82 points, and his daily life and work ability were significantly improved.

[0129] After four treatments, Mr. Wang's symptoms were basically relieved and all his physical indicators returned to normal levels. The doctor recommended that Mr. Wang undergo a follow-up examination every month to closely monitor changes in his condition. If there are any signs of recurrence of symptoms, acupuncture treatment should be taken immediately.

[0130] Through this case, we can see that the multi-needle electroacupuncture device provided by the present invention has significant advantages in treating neuralgia. First, the device can accurately cover multiple acupuncture points and realize personalized treatment plans by independently controlling the current parameters of each needle. Secondly, the built-in multi-mode control function of the device can flexibly switch treatment parameters according to the characteristics of different diseases, greatly improving the targeted treatment. In addition, the device also has real-time monitoring and automatic adjustment functions, which can dynamically optimize the treatment plan to ensure the stability and repeatability of the therapeutic effect.

[0131] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
