Description

Technical Field

[0001] This invention relates to the field of neurorehabilitation technology, specifically to a desktop meridional neuromuscular electrical stimulation system and electrical stimulator. Background Technology

[0002] Neuromuscular electrical stimulation (EMS) technology, as an important means of clinical rehabilitation and functional regulation, has been widely used in nerve injury repair, muscle function recovery, and adjunctive treatment of chronic diseases. Its core principle is to stimulate acupoints or neuromuscular tissues with electrical signals of specific parameters to elicit physiological responses and achieve therapeutic goals. Meanwhile, traditional Chinese medicine's Meridian Flow Therapy, based on the theory of "correspondence between man and nature," believes that the flow of Qi and blood in the body's meridians changes cyclically with the twelve two-hour periods of the day. Specific times correspond to the waxing and waning of Qi and blood in specific meridians, and choosing the right time for treatment can enhance the therapeutic effect. This theory has accumulated rich practical experience in TCM clinical applications. With the increasing demand for precise and objective treatment in modern medicine, the combination of traditional EMS technology and the Meridian Flow Therapy has become a development trend. However, how to transform traditional empirical acupoint location and Qi and blood assessment into a quantifiable and controllable modern technical system, and how to dynamically adapt EMS parameters to the rhythm of meridian Qi and blood flow, have become key directions for promoting technological upgrades in this field, and also provide technological exploration space for the development of related equipment.

[0003] Traditional neuromuscular electrical stimulation (EMS) techniques have several limitations in application. First, in the acupoint location stage, they rely excessively on the operator's clinical experience, lacking standardized location methods. This makes it impossible to objectively calibrate based on individual body position differences and changes in body surface characteristics, easily leading to stimulation position deviations and affecting targeted treatment efficacy. Second, the stimulation parameters of traditional devices are mostly fixed preset modes, failing to consider the influence of the meridian flow pattern on the state of Qi and blood in the meridians, and unable to adjust parameters based on the individual's real-time Qi and blood fullness and changing trends. This makes it difficult to match the rhythmic characteristics of the dynamic flow of Qi and blood in the meridians, resulting in a lack of personalized and adaptable treatment plans. Third, the judgment of the Qi and blood state at acupoints in traditional therapies relies heavily on subjective feelings, lacking quantitative indicators based on physiological signals. This makes it impossible to monitor Qi and blood changes in real time and accurately, and there is no closed-loop feedback mechanism for efficacy and parameter adjustment. It is also impossible to iteratively optimize the treatment plan based on physiological responses during the treatment process, resulting in insufficient stability of treatment effects and failing to meet the high requirements of modern medicine for treatment precision and effectiveness. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a desktop Meridian Flow Neuromuscular Electrical Stimulation System and Electrical Stimulator. The core of this invention lies in combining the Meridian Flow theory with modern electrical stimulation technology. The system achieves personalized electrical stimulation treatment through modules such as precise acupoint positioning, Qi and blood quantification, intelligent mapping of stimulation parameters, and closed-loop optimization of therapeutic effects. It integrates a high-definition camera and multiple types of sensors, relies on the Meridian Flow time database, dynamically adjusts stimulation parameters, synchronously monitors treatment responses, optimizes therapeutic effects, and provides a brand-new solution for the modernization of traditional Chinese medicine treatment.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: In one aspect, a desktop meridional neuromuscular electrical stimulation system, comprising:

[0006] Acupoint Precision Location Module: Integrates image acquisition components to collect human body surface features, extracts acupoint-related features after image preprocessing, performs positioning correction by combining body position-acupoint coordinate mapping database, and outputs acupoint three-dimensional coordinates through multi-feature coupled acupoint positioning algorithm;

[0007] Qi and Blood Quantification Module: Through surface electromyography electrodes, dual electrode configuration, three-lead electrocardiogram electrodes and near-infrared spectroscopy sensors, electromyography, skin conductance response, heart rate variability and blood oxygen microcirculation signals are collected respectively. Combined with the meridian flow time pattern, the Qi and Blood fullness index is calculated through the meridian flow-physiological coupling Qi and Blood Quantification algorithm.

[0008] Stimulation parameter mapping module: Based on the meridian flow time database and combined with the qi and blood fullness data, a dynamic meridian qi and blood flow map is constructed to determine the qi and blood status of acupoints. The personalized stimulation parameter combination containing frequency, intensity and duration is generated through the tonification and sedation stimulation parameter mapping algorithm.

[0009] The Meridian Flow Time Database contains data on the correspondence between the twelve two-hour periods and meridians, qi and blood. Specifically, the 24 hours of a day are divided into twelve two-hour periods, each associated with a main meridian and all acupoints belonging to that meridian. The database stores the time intervals of the initial peak, peak, and gradual decline of qi and blood in the main meridian of each two-hour period, as well as the reference values ​​of the peak qi and blood of each acupoint in the corresponding two-hour period. All data are constructed based on human meridian theory and clinical statistical results.

[0010] The method for determining the Qi and blood status of acupoints is as follows: First, retrieve the reference value of the peak Qi and blood of the corresponding acupoints at the current time from the Meridian Flow Time Database. ; Calculate real-time blood and qi saturation and ratio Combined with the rate of change in Qi and blood ,when and At that time, it was determined that the Qi and blood were about to arrive but had not yet arrived; when At that time, it was determined that the Qi and blood were at their peak; when and At that time, it was determined that the Qi and blood had declined;

[0011] Electrical stimulation execution module: Equipped with multiple types of electrodes and multi-channel output interfaces, it reads personalized stimulation parameters through an embedded controller, drives the electrodes to apply electrical stimulation to precisely located acupoints, and dynamically adjusts the stimulation parameters according to the data on the fullness of Qi and blood.

[0012] The efficacy closed-loop optimization module: By monitoring the temperature and impedance changes of the acupoint area through sensors, and combining the difference in Qi and blood saturation before and after treatment, the efficacy quantification closed-loop optimization algorithm generates an efficacy score. The stimulation parameters are iteratively optimized based on the score and fed back to the stimulation parameter mapping module, and finally, an efficacy quantification report is generated.

[0013] Furthermore, in the acupoint precise positioning module, the image acquisition component includes a high-definition camera and an infrared thermal imager; the acupoint-related features include morphological features and temperature features. The morphological features are the geometric parameters of the skin folds and pore distribution around the acupoint, and the temperature features are the temperature difference between the acupoint area and the surrounding tissue; the body position-acupoint coordinate mapping database contains standard three-dimensional coordinates of acupoints in three basic body positions: supine, prone, and sitting. The coordinate data is generated based on the standard human anatomy model and supports the addition of custom body position coordinates.

[0014] Furthermore, in the acupoint precise positioning module, the mathematical expression of the multi-feature coupled acupoint positioning algorithm is: ,in, The final output is the actual three-dimensional coordinates of the acupoint. The reference coordinates for acupoints under standard body position. This is the body position adaptation coefficient. To locate the correction vector, The temperature difference between the acupoint and the surrounding tissues. For skin texture morphology similarity, , Fixed weights for temperature and morphological characteristics.

[0015] Furthermore, in the stimulation parameter mapping module, combining the meridian flow time pattern means that: the system has a built-in table of the correspondence between the twelve two-hour periods and the meridian qi and blood. The twelve two-hour periods are divided into 24 hours per day, with each two-hour period corresponding to a main meridian and the initial, peak, and gradual decline stages of the qi and blood in that meridian; the system obtains the current two-hour period in real time and calls the characteristic parameters of the rise and fall of the qi and blood in the main meridian of the corresponding two-hour period as the input parameters of the meridian flow-physiological coupling qi and blood quantification algorithm.

[0016] Furthermore, in the stimulation parameter mapping module, the mathematical expression of the meridian flow-physiological coupling Qi and blood quantification algorithm is: ,in, It is the final calculated index of the fullness of Qi and blood in acupoints. It is the first Real-time acquisition values ​​of physiological signals, For electromyographic signals, For skin conductance signals, For heart rate variability signals, This is a signal of blood oxygen microcirculation. For dynamic weights, , The clinically calibrated threshold for the corresponding signal. The meridian flow phase factor is t, where t is the current time. For the rate of change of Qi and Blood, Trend weight.

[0017] Furthermore, the specific steps for constructing a dynamic meridian qi and blood flow map in the stimulation parameter mapping module are as follows:

[0018] (1) Retrieve the spatial distribution data of the main meridian and its corresponding acupoints from the Meridian Flow Time Database and establish a three-dimensional spatial model of meridian-acupoint;

[0019] (2) Read the real-time Qi and Blood Quantity data output by the Qi and Blood Quantification Module and associate the Qi and Blood Quantity value of each acupoint with the corresponding acupoint node in the three-dimensional spatial model;

[0020] (3) The blood and qi fullness values ​​of acupoint nodes are normalized and mapped to acupoints and meridian paths in the three-dimensional space model through color gradient, where red represents high fullness and blue represents low fullness.

[0021] (4) Calculate the flow vector of Qi and blood in the meridians based on the rate of change of Qi and blood, and use dynamic arrows to mark the flow direction in the three-dimensional space model. The length of the arrow is positively correlated with the absolute value of the rate of change of Qi and blood.

[0022] Steps (2)-(4) are repeated every 2 seconds based on the updated Qi and Blood Fiber data to dynamically refresh the graph.

[0023] Furthermore, in the stimulation parameter mapping module, the corresponding formula for the tonifying and purging stimulation parameter mapping algorithm for different Qi and blood states is as follows: When hour, , , when hour, ;when hour, , , ,in, , , It refers to the final output of stimulation frequency, stimulation intensity, and stimulation duration. , To calibrate baseline parameters for clinical use, This represents the peak value of Qi and blood at the acupoint. For the rate of change of Qi and Blood, It is the final calculated index of the fullness of Qi and blood in acupoints. It is the meridional phase factor.

[0024] Furthermore, the specific steps in the electrical stimulation execution module for dynamically adjusting the stimulation parameters based on the blood and qi fullness data are as follows:

[0025] The embedded controller acquires real-time Qi and blood saturation data from the Qi and blood quantification module every 10 seconds. ;

[0026] Calculate the difference between the current Qi and Blood sufficiency and the Qi and Blood sufficiency at the previous adjustment time. ,in This is data from the previous moment.

[0027] when When this happens, the parameter adjustment process is initiated;

[0028] like Reduce the stimulus intensity by 5 mA and the frequency by 1 Hz; if Increase the stimulation intensity by 5 mA and the frequency by 1 Hz;

[0029] The adjusted parameters are synchronized to the corresponding electrodes via a multi-channel output interface to continue electrical stimulation and update the parameters simultaneously. For the present .

[0030] Furthermore, in the efficacy quantification closed-loop optimization module, the mathematical expression of the efficacy quantification closed-loop optimization algorithm is: ,in, It is the final output of the treatment score. As the core weight, It is the difference in the abundance of Qi and blood before and after treatment. This represents the impedance difference in the acupoint area. It is the temperature difference of the acupoint area before and after treatment.

[0031] On the other hand, a desktop meridional neuromuscular electrical stimulator includes:

[0032] Embedded control unit: Establishes data communication with the system, receives personalized stimulation parameters, outputs control commands, and synchronously collects physiological feedback data during the treatment process;

[0033] Multiple types of electrode components: including circular patch electrodes, needle electrodes and sheet electrodes, to adapt to different acupoint shapes and stimulation needs, and the electrode surface is provided with a conductive gel layer.

[0034] Multi-channel output interface: Includes at least 8 independent output channels, supports simultaneous stimulation of multiple acupoints, and has an inter-channel interference of ≤5%;

[0035] Data acquisition interface: compatible with surface electromyography electrodes, electrocardiogram electrodes and near-infrared spectroscopy sensors, transmitting physiological signals to the system's blood and qi quantification module in real time;

[0036] Display unit: Uses a touch LCD screen to display dynamic meridian qi and blood flow graphs, current stimulation parameters, qi and blood fullness data, and efficacy scores;

[0037] Control panel: Features a position selection button, a start / stop button, and an emergency stop button, and supports manual fine-tuning of stimulation intensity;

[0038] Power module: Provides both AC and DC power supply modes;

[0039] Body structure: It adopts a desktop design and is equipped with electrode storage slots and sensor interface areas.

[0040] Compared with existing technologies, this desktop meridional neuromuscular electrical stimulation system and stimulator have the following beneficial effects:

[0041] I. This invention integrates image acquisition components and multi-feature coupled positioning algorithms, combined with a body position-acupoint coordinate mapping database, to achieve precise three-dimensional coordinate calibration of acupoints. This eliminates the reliance on experience in traditional acupoint positioning, achieving objective and standardized positioning. Simultaneously, it integrates multi-type physiological signal acquisition technologies and the meridian flow time pattern to construct a dynamic meridian qi and blood flow atlas, capturing the fullness and changing trends of qi and blood at acupoints in real time. This transforms traditional meridian qi and blood theory into quantifiable objective indicators. This deep integration of precise positioning and dynamic quantification allows electrical stimulation to strictly match the meridian qi and blood flow rhythm, targeting corresponding acupoints and improving the pertinence and adaptability of stimulation. This promotes the transformation of traditional meridian flow therapy from experience-based to precise and scientific, providing theoretical support for neuromuscular electrical stimulation that is more in line with human physiological rhythms, significantly enhancing the professionalism and effectiveness of treatment.

[0042] II. This invention establishes a correspondence between the meridian flow time and the Qi and blood of the meridians, combines a Qi and blood state judgment system with the principles of tonification and sedation, and generates personalized stimulation programs adapted to different Qi and blood rhythms. It dynamically matches the trends of Qi and blood changes and constructs a closed-loop optimization mechanism for therapeutic effects. It monitors the changes in physiological indicators of acupoint areas in real time during treatment, quantifies the treatment effect, and iteratively optimizes stimulation parameters to form a complete treatment feedback loop. This personalized dynamic adjustment and closed-loop optimization design breaks through the limitations of fixed parameters and lack of adaptability of traditional electrical stimulation devices. It ensures that the treatment plan always fits the individual's real-time physiological state, adheres to the core logic of traditional Chinese medicine meridian regulation, and incorporates the precise control advantages of modern engineering technology, improving the stability and reliability of treatment effects. It provides a more efficient and adaptable solution for the clinical application of neuromuscular electrical stimulation technology and promotes the deep integration of traditional Chinese medicine theory and modern medical technology.

[0049] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0050] Example 1:

[0051] The connection and collaborative workflow of the system and devices.

[0052] This embodiment focuses on the desktop meridional neuromuscular electrical stimulation system (hereinafter referred to as the "system") and the desktop meridional neuromuscular electrical stimulation device, such as Figure 2 The functions and linkage mechanism of the device (hereinafter referred to as "the device") shown above, through the coordinated operation of each link, realize a complete treatment closed loop from acupoint location to efficacy evaluation.

[0053] Device startup and communication setup: Connect the device to an AC or DC power supply. After turning on the power module, the device's embedded control unit automatically initializes and establishes a stable data communication link with the system. The system then activates all functional modules, including the acupoint precise positioning module and the Qi and blood quantification module. The device's display unit simultaneously lights up and enters the standby interface, such as... Figure 3 As shown, the system and device now have bidirectional data transmission capabilities, laying the foundation for subsequent operations.

[0054] Body Position Selection and Precise Acupoint Location: Users select any basic body position (supine, prone, or sitting) via the device's control panel. Custom body position parameters can also be added for specific needs. The device's image acquisition component, consisting of a high-definition camera and an infrared thermal imager, begins collecting morphological and temperature features of the human body surface. Morphological features include geometric parameters such as the direction of skin folds around the acupoint and the density of pores. Temperature features are the temperature difference between the acupoint area and surrounding tissues. This raw data is transmitted in real-time to the system's precise acupoint location module via the device's data acquisition interface. The module calls the standard three-dimensional coordinates of the corresponding acupoints in the body position-acupoint coordinate mapping database and processes the data using a multi-feature coupled acupoint location algorithm. Finally, it outputs the precise three-dimensional coordinates of the actual acupoints. The mathematical expression of the multi-feature coupled acupoint location algorithm is: ,in, The final output is the actual three-dimensional coordinates of the acupoint. The reference coordinates for acupoints under standard body position. This is the body position adaptation coefficient. To locate the correction vector, The temperature difference between the acupoint and the surrounding tissues. For skin texture morphology similarity, , The temperature and morphological characteristics are assigned fixed weights, and this coordinate data is fed back to the device's embedded control unit to ensure that subsequent electrical stimulation can accurately act on the target acupoint.

[0055] Physiological Signal Acquisition and Qi and Blood Quantification: The device's surface electromyography electrodes, dual electrodes, three-lead electrocardiogram electrodes, and near-infrared spectral sensors are simultaneously activated to acquire human electromyography signals, skin conductance signals, heart rate variability signals, and blood oxygen microcirculation signals, respectively. All acquired physiological signals are continuously transmitted to the system's Qi and Blood Quantification module through the data acquisition interface. The system calls the Meridian Flow Time Database to obtain the main meridian information corresponding to the current time and the initial, peak, and declining stages of Qi and Blood in that meridian. Combining these time patterns, the Meridian Flow-Physiological Coupled Qi and Blood Quantification Algorithm is used to analyze and calculate the four types of physiological signals, deriving the Qi and Blood fullness index and Qi and Blood change rate of each acupoint. The mathematical expression of the Meridian Flow-Physiological Coupled Qi and Blood Quantification Algorithm is: ,in, It is the final calculated index of the fullness of Qi and blood in acupoints. It is the first Real-time acquisition values ​​of physiological signals, For electromyographic signals, For skin conductance signals, For heart rate variability signals, This is a signal of blood oxygen microcirculation. For dynamic weights, , The clinically calibrated threshold for the corresponding signal. The meridian flow phase factor is t, where t is the current time. For the rate of change of Qi and Blood, The trend weights provide a quantitative basis for subsequent judgment of the Qi and blood status of acupoints.

[0056] Stimulation Parameter Generation and Transmission: The system's stimulation parameter mapping module receives data on Qi and blood fullness and Qi and blood change rate output by the Qi and blood quantification module. It then retrieves relevant information from the meridian flow time database to construct a dynamic meridian Qi and blood flow map. This map clearly displays the degree of Qi and blood fullness at each acupoint and the direction of Qi and blood flow within the meridians. Based on the Qi and blood status of the acupoints reflected in the map, the module uses the following stimulation parameter mapping algorithm to generate personalized stimulation parameter combinations, including stimulation frequency, intensity, and duration. The following formula is used for different Qi and blood states: When... hour, , , when hour, ;when hour, , , ,in, , , It refers to the final output of stimulation frequency, stimulation intensity, and stimulation duration. , To calibrate baseline parameters for clinical use, This represents the peak value of Qi and blood at the acupoint. For the rate of change of Qi and Blood, It is the final calculated index of the fullness of Qi and blood in acupoints. It is the meridional phase factor. This parameter combination is transmitted to the embedded control unit of the device through a data communication link. The display unit of the device displays these parameters synchronously, which is convenient for operators to confirm.

[0057] Electrical stimulation execution and dynamic parameter adjustment: The device's embedded control unit drives various types of electrode components through a multi-channel output interface based on the received personalized stimulation parameters. This multi-channel output interface contains at least 8 independent output channels with inter-channel interference ≤5%, supporting simultaneous stimulation of multiple acupoints. The various electrode components are selected based on the acupoint morphology and stimulation requirements, using circular patch electrodes, needle electrodes, or sheet electrodes. The conductive gel layer on the electrode surface enhances conductivity and skin adhesion. During electrical stimulation, the device acquires real-time Qi and blood saturation data from the Qi and blood quantification module every 10 seconds. The embedded control unit calculates the difference between the current data and the Qi and blood saturation data from the previous adjustment time. ,in Using data from the previous moment, if the absolute value of the difference is greater than 1, the parameter adjustment process is initiated: if the difference is positive, the stimulation intensity is reduced by 5mA and the stimulation frequency is reduced by 1Hz; if the difference is negative, the stimulation intensity is increased by 5mA and the stimulation frequency is increased by 1Hz. The adjusted parameters are synchronized to the corresponding electrodes through a multi-channel output interface to ensure that the electrical stimulation is always adapted to the Qi and blood status of the acupoint.

[0058] Therapeutic effect assessment and parameter optimization: During treatment, the device continuously monitors temperature and impedance changes in the acupoint area and transmits this data in real time to the system's therapeutic effect closed-loop optimization module. The module combines the difference in Qi and blood fullness before and after treatment and uses a therapeutic effect quantification closed-loop optimization algorithm to calculate and generate a therapeutic effect score. The mathematical expression of the therapeutic effect quantification closed-loop optimization algorithm is as follows: ,in, It is the final output of the treatment score. As the core weight, It is the difference in the abundance of Qi and blood before and after treatment. This represents the impedance difference in the acupoint area. It measures the temperature difference in the acupoint area before and after treatment. Based on the scoring results, the stimulation parameters are iteratively optimized, and the optimized parameters are fed back to the system's stimulation parameter mapping module. This module then transmits the data to the device's embedded control unit, achieving dynamic optimization of the stimulation parameters. After treatment, the system integrates all treatment data to generate a quantitative efficacy report, which is displayed on the device's display unit for operators and users to view the treatment effect.

[0059] In summary, this embodiment clearly establishes the synergistic relationship between the desktop metropolitan neuromuscular electrical stimulation system and the device, forming a complete closed loop from activation to efficacy evaluation. Communication is established between the device and the system upon power-on. Combined with body position selection via the control panel, features are collected using a high-definition camera and infrared thermal imager. Precise positioning is achieved through the system's multi-feature coupled acupoint positioning algorithm. Then, physiological signals are collected using multiple sensors, and Qi and blood data are obtained through the metropolitan-physiological coupling Qi and blood quantification algorithm. Stimulation parameters are generated based on the tonification and sedation algorithm. The device's multi-channel interface drives the electrodes to perform stimulation, dynamically adjusting the parameters every 10 seconds. Finally, the efficacy is evaluated and parameters are optimized through a efficacy quantification closed-loop optimization algorithm, ensuring the system's functionality is fully implemented through the device, achieving personalized and precise electrical stimulation.

[0060] Example 2:

[0061] Application scenarios for the treatment of chronic low back pain patients based on system and device collaboration.

[0062] This embodiment takes patients with chronic low back pain as the treatment target. Based on the system and device linkage relationship established in Embodiment 1, the treatment is carried out at Chenshi (7:00-9:00). This time corresponds to the Stomach Meridian of Foot Yangming, which is in line with the correspondence between the main meridians and Qi and blood in the Meridian Flow Time Database. The treatment process revolves around the relevant acupoints of the waist.

[0063] Treatment Preparation and Equipment Start-up: After the patient enters the treatment room, they assume a prone position with the assistance of the operator. The operator selects the sheet electrode assembly of the device based on the shape of the acupoints on the patient's lower back and attaches the electrodes to acupoints related to lower back pain treatment, such as Shenshu, Dachangshu, and Weizhong, ensuring close contact between the electrodes and the skin without displacement. The operator selects the "prone" position on the device's control panel, presses the start button to turn on the device's power, and the device's embedded control unit quickly establishes data communication with the system. The system activates all functional modules, and the device's display unit shows "Equipment Ready," simultaneously displaying the current time as Chenshi (7-9 AM) and the corresponding main meridian as the Stomach Meridian of Foot Yangming, facilitating the operator's confirmation of basic treatment parameters, such as... Figure 1 As shown.

[0064] Precise location of acupoints in the lower back: The device's high-definition camera and infrared thermal imager begin collecting the morphological and temperature characteristics of the patient's lower back. Morphological characteristics include the distribution of skin folds around the Shenshu acupoint and the arrangement of pores near the Dachangshu acupoint. Temperature characteristics are the temperature difference between each target acupoint and the surrounding lumbar tissue. This collected data is transmitted to the system's precise acupoint location module through the device's data acquisition interface. The module calls upon the standard three-dimensional coordinates of acupoints in the prone position from the body position-acupoint coordinate mapping database, and combines this with a multi-feature coupled acupoint location algorithm to correct the collected data. Finally, it outputs the actual three-dimensional coordinates of the Shenshu, Dachangshu, and Weizhong acupoints. The mathematical expression of the multi-feature coupled acupoint location algorithm is: The coordinate data is fed back to the embedded control unit of the device. The display unit of the device marks the location of each acupoint in the form of visual icons. After the operator confirms that the positioning is accurate, he issues the "positioning complete" command through the operation panel.

[0065] Monitoring of Qi and Blood Status at Lumbar Acupoints: The device's surface electromyography electrodes collect electromyographic signals from the lumbar muscles, dual electrodes collect skin conductance signals, three-lead electrocardiogram electrodes collect heart rate variability signals, and a near-infrared spectral sensor collects blood oxygen microcirculation signals from the lumbar acupoint area. All physiological signals are transmitted in real time to the system's Qi and Blood Quantification module. The system calls upon data from the Meridian Flow Time Database on the initial, peak, and declining stages of Qi and Blood in the Stomach Meridian of Foot Yangming during the Chen hour (7-9 AM). Combining these time-based patterns, the Meridian Flow-Physiological Coupled Qi and Blood Quantification Algorithm is used to analyze the four types of physiological signals. The mathematical expression of the Meridian Flow-Physiological Coupled Qi and Blood Quantification Algorithm is: The system calculated the Qi and blood fullness index and Qi and blood change rate of the Shenshu, Dachangshu, and Weizhong acupoints. It was found that the patient's Dachangshu acupoint had low Qi and blood fullness and a negative Qi and blood change rate, indicating that the acupoint was in a state of "Qi and blood deficiency". The system's stimulation parameter mapping module then constructed a dynamic meridian Qi and blood flow map, marking the Qi and blood fullness of each acupoint on the three-dimensional spatial model of the Stomach Meridian of Foot Yangming using color gradients, where red represents high fullness and blue represents low fullness. At the same time, the Qi and blood flow vector within the meridian was calculated based on the Qi and blood change rate, and the flow direction was marked with dynamic arrows. The arrow length is positively correlated with the absolute value of the Qi and blood change rate. The map is refreshed every 2 seconds based on the updated Qi and blood data and is simultaneously displayed on the device's touch screen LCD, allowing the operator to observe the changes in Qi and blood at the acupoints in the waist in real time.

[0066] Personalized electrical stimulation execution: The system's stimulation parameter mapping module, based on the "decayed Qi and blood" state of the Dachangshu acupoint and combined with the Qi and blood conditions of other acupoints, uses the accompanying tonification and sedation stimulation parameter mapping algorithm to generate personalized stimulation parameter combinations. The accompanying tonification and sedation stimulation parameter mapping algorithm uses corresponding formulas for different Qi and blood states: When... hour, , , when hour, ;when hour, , , The parameters are adjusted based on clinically calibrated baseline parameters to ensure that the stimulation frequency, intensity, and duration are adapted to the trend of Qi and blood decline. After the parameter combination is transmitted to the embedded control unit of the device, the device drives the sheet electrode through a multi-channel output interface (8 independent channels, inter-channel interference ≤5%) to simultaneously apply electrical stimulation to the Shenshu, Dachangshu, and Weizhong acupoints, ensuring that each acupoint receives a precise stimulation signal.

[0067] Dynamic adjustment of stimulation parameters: During treatment, the device acquires real-time data on the fullness of Qi and blood in the patient's lumbar acupoints from the system's Qi and blood quantification module every 10 seconds. The embedded control unit calculates the difference between the current Qi and blood fullness data and the data from the previous moment. When the absolute value of the difference in Qi and blood saturation at the Dachangshu acupoint is greater than 1 and the difference is negative, the device increases the stimulation intensity by 5mA and the stimulation frequency by 1Hz according to the system feedback instructions. If the difference in Qi and blood saturation at the acupoint turns positive and the absolute value is greater than 1, the stimulation intensity is then reduced by 5mA and the stimulation frequency is reduced by 1Hz. Through such dynamic adjustment, the intensity and frequency of electrical stimulation are always adapted to the changes in Qi and blood at the acupoints in the waist.

[0068] Treatment efficacy evaluation and feedback: After the treatment reaches the duration set by personalized parameters, the device automatically stops electrical stimulation. The embedded control unit transmits complete data on changes in blood and qi fullness at the lumbar acupoints, temperature changes in the acupoint area, and impedance changes throughout the treatment to the system's efficacy closed-loop optimization module. The module combines the difference in blood and qi fullness before and after treatment and uses an efficacy quantification closed-loop optimization algorithm to calculate and generate an efficacy score. The mathematical expression of the efficacy quantification closed-loop optimization algorithm is: The system iteratively optimizes stimulation parameters based on the scoring results and feeds the optimized parameters back to the system's stimulation parameter mapping module. This module then transmits the data to the device's embedded control unit, providing a basis for subsequent treatment plan adjustments. Simultaneously, the system integrates treatment data to generate a quantitative efficacy report, which is displayed on the device's display unit. Operators can explain the treatment effects to patients based on the report, allowing patients to clearly understand the improvement in their lumbar blood circulation during the treatment.

[0069] In summary, this embodiment uses the scenario of treating chronic low back pain patients during the Chenshi (7-9 AM) period as an example, and implements the system of Embodiment 1 and as shown in the example below. Figure 4The illustrated device demonstrates its synergistic relationship. Around the corresponding time of day for the Stomach Meridian of Foot Yangming, the patient lies prone, and sheet electrodes are applied to acupoints on the lower back. After the device and system are activated through communication, lumbar features are collected, and acupoints are located using a multi-feature coupling algorithm. Physiological signals are acquired through sensors, and the state of Qi and blood is determined using a meridian-physiological coupling algorithm. Parameters are generated using a tonifying and reducing algorithm, and the device drives the electrodes through multiple channels for stimulation.
