[0015] Beneficial effects of the present invention: The physical stimulation-driven lymphatic circulation and cognitive enhancement system proposed in the present invention is generally composed of a physical stimulation frequency impact evaluation module, a stimulation mechanical vibration analysis module, a lymphatic circulation vibration calibration module and a stimulation frequency drive adjustment module. Compared with the prior art, the beneficial effect of the present application lies in the use of pressure sensors and temperature sensors to monitor the physical stimulation generated by low-frequency pulse electromagnetic equipment in real time, so that these sensors can accurately measure the pressure and skin surface temperature generated during the physical stimulation process, both of which are crucial to the stimulation effect. The pressure sensor helps to evaluate the intensity of the stimulation force to ensure that the physical stimulation is within an acceptable range and does not cause excessive load on the skin or tissue; the temperature sensor is used to monitor whether discomfort or overheating occurs during the stimulation process. Through real-time collection of pressure and temperature data, the effect of ultrasonic stimulation can be dynamically analyzed, and an important basis for subsequent adjustments is provided. Based on these data, the impact of changes in ultrasonic stimulation frequency on pressure and temperature is analyzed and evaluated, thereby deriving pressure influence factors and temperature influence factors. These factors lay the foundation for further mechanical vibration analysis to ensure that the stimulation at each frequency meets the expected effect. Secondly, based on the previously obtained pressure influencing factors and temperature influencing factors, the ultrasonic waves generated by the low-frequency pulse electromagnetic device are analyzed to stimulate mechanical vibrations. Mechanical vibration is an important factor in the physical stimulation stimulated by the low-frequency pulse electromagnetic device. It directly affects the force and fluid dynamic response of tissues and cells. By analyzing the pressure influencing factors and the temperature influencing factors, the vibration effect produced by ultrasonic stimulation and the changes in the mechanical effect caused can be determined. At this time, through the study of the relationship between ultrasonic frequency and mechanical vibration, the impact of physical stimulation on lymph flow rate and brain electrical neural activity can be more accurately predicted, and the stimulation frequency can be adjusted accordingly. This not only helps to fine-tune the low-frequency pulse electromagnetic device, but also provides data support for the subsequent lymphatic circulation calibration process, so as to accurately evaluate the specific impact of factors such as the intensity of physical stimulation and vibration effects on lymphatic circulation and cognitive improvement. Then, by combining the lymph flow velocity, an efficient feedback mechanism is provided to optimize the stimulation effect of the low-frequency pulse electromagnetic device. By obtaining the synchronous data of the lymph flow velocity and the EEG neural activity signal, and performing neurocognitive level analysis on the EEG signal, the impact of physical stimulation on the nervous system level can be accurately evaluated. The EEG neural activity signal reflects the cognitive response and changes in neural activity of the brain when receiving physical stimulation, which further helps to determine the effectiveness of the stimulation program. The vibration response calibration mechanism can adjust the lymph flow velocity in real time according to the vibration effect of the physical stimulation, so that it is within an ideal flow velocity range. Through this link, it can be ensured that the low-frequency pulse electromagnetic device not only has a cognitive improvement effect on the nervous system, but also can synchronously improve the flow state of the lymphatic system.Finally, by combining the analysis results of lymph flow velocity and EEG cognitive level, a multi-layer perceptron was used to perform lymphatic circulation cognitive regression analysis, which can construct a correlation mapping relationship between lymph flow velocity and EEG cognitive level. This regression analysis can reveal the potential connection between stimulation frequency and EEG cognitive level, thereby providing a scientific basis for adjusting the stimulation frequency of low-frequency pulse electromagnetic equipment. Through this model analysis based on the combination of flow velocity and EEG activity, the optimal stimulation frequency range can be found to maximize the fluidity of the lymphatic system and the cognitive level of the nervous system. This result will directly affect the driving adjustment plan of the low-frequency pulse electromagnetic equipment, which not only improves the effect of cognitive level, but also better promotes the lymphatic circulation process.

[0021] In the embodiment of the present invention, please refer to Figure 1 FIG. 1 is a schematic diagram of the modules of the physical stimulation-driven lymphatic circulation and cognitive enhancement system of the present invention. In this example, the physical stimulation-driven lymphatic circulation and cognitive enhancement system includes the following modules: S1: A physical stimulation frequency impact assessment module, which is used to use a pressure sensor and a temperature sensor to monitor in real time the corresponding physical stimulation pressure and stimulated skin surface temperature during the physical stimulation driving process generated by the low-frequency pulse electromagnetic device, and to assess the stimulation frequency impact of the physical stimulation ultrasound corresponding to the low-frequency pulse electromagnetic device based on the physical stimulation pressure and stimulated skin surface temperature, so as to obtain the pressure impact factor and temperature impact factor corresponding to the ultrasound stimulation frequency; In an embodiment of the present invention, a plurality of pressure sensors and temperature sensors are arranged around a low-frequency pulse electromagnetic device to monitor in real time the physical stimulation applied by the device to the skin surface during operation. The pressure sensor can accurately measure the pressure changes on the skin surface under electromagnetic stimulation of different frequencies. The sensor needs to have a high response speed and accuracy to ensure that it can capture the tiny pressure fluctuations generated by the low-frequency pulse electromagnetic device. The temperature sensor should be arranged on the skin surface to accurately reflect the skin temperature changes caused by the device during operation. In this process, the data collected by the sensor is transmitted to the data processing system through the data acquisition module, and the temperature and pressure data are recorded and analyzed in real time. Subsequently, based on the pressure data and the temperature data, the relationship between the pressure change and the temperature change caused by the low-frequency pulse electromagnetic device at different stimulation frequencies can be analyzed, and the influence of the ultrasonic stimulation frequency on the physical stimulation pressure and temperature can be further evaluated, thereby generating the pressure influence factor and the temperature influence factor. The core of this evaluation process is to explore the quantitative relationship between the ultrasonic stimulation frequency and the pressure and temperature by establishing a model, and finally obtain the pressure influence factor and the temperature influence factor corresponding to the ultrasonic stimulation frequency.

[0022] S2: a stimulation mechanical vibration analysis module, used to perform stimulation mechanical vibration analysis on the physical stimulation ultrasonic wave corresponding to the low-frequency pulse electromagnetic device based on the pressure influence factor and the temperature influence factor corresponding to the ultrasonic stimulation frequency, so as to generate a physical stimulation mechanical vibration effect; In an embodiment of the present invention, a relationship model between ultrasonic stimulation frequency and physical stimulation mechanical vibration is constructed by utilizing the pressure influence factor and temperature influence factor previously acquired. In order to perform this analysis, the physical stimulation ultrasonic frequency generated by the low-frequency pulse electromagnetic device and the pressure and temperature influence factors must first be parameterized and input into the mechanical vibration analysis software. The software should have the function of simulating the mechanical vibration effect of physical stimulation and performing frequency response analysis. By analyzing the influence of different ultrasonic stimulation frequencies on mechanical vibration, the mechanical vibration effect generated by physical stimulation can be obtained. This effect can be used to further infer the influence of stimulation on human lymph flow rate and brain electrical neural activity. In this process, the mechanical response characteristics of the device at different operating frequencies must be taken into account, and the vibration model must be calibrated in combination with sensor data to ensure the accuracy of the analysis results, and finally a physical space field model corresponding to the physical stimulation mechanical vibration effect is generated.

[0023] S3: Lymphatic flow vibration calibration module, used to obtain lymphatic flow velocity and EEG neural activity signals, and perform neurocognitive level analysis on the EEG neural activity signals to obtain the EEG neural activity cognitive level; perform vibration response calibration on the lymphatic flow velocity based on the mechanical vibration effect of physical stimulation to generate the corresponding lymphatic flow velocity under physical stimulation mechanical vibration; In an embodiment of the present invention, by acquiring the lymph flow velocity and the EEG neural activity signal, and performing cognitive analysis on the EEG signal, first, the lymph flow velocity data is acquired by an embedded sensor or a blood flow monitoring device. These sensors can obtain relevant data by monitoring the pressure change in the lymphatic duct or directly measuring the flow velocity. At the same time, an electroencephalogram (EEG) device is used to collect EEG signals and analyze the neural activity of the brain under the physical stimulation of a low-frequency pulse electromagnetic device. The collected EEG signals need to undergo digital signal processing and feature extraction to identify brain activity patterns under different cognitive states. Through multi-channel EEG data analysis, the neurocognitive level, such as changes in cognitive functions such as attention and memory, can be evaluated. Then, the EEG signal is combined with the lymph flow velocity data, and their relationship is analyzed. The vibration response calibration is performed according to the influence of the mechanical vibration effect on the flow velocity, so as to obtain the lymph flow velocity under physical stimulation. This process requires precise control of the time synchronization and calibration of the data to ensure the effective fusion of the two data, and finally generate the lymph flow velocity corresponding to the physical stimulation mechanical vibration.

[0024] S4: Stimulation frequency drive adjustment module, which is used to perform lymphatic circulation cognitive regression analysis on the cognitive level of EEG neural activity based on the corresponding lymphatic fluid flow velocity under physical stimulation mechanical vibration and combined with a multi-layer perceptron to obtain the correlation mapping relationship between the lymphatic fluid flow velocity and the EEG cognitive level; based on the correlation mapping relationship between the lymphatic fluid flow velocity and the EEG cognitive level, the stimulation frequency drive adjustment of the physical stimulation ultrasound corresponding to the low-frequency pulse electromagnetic device is performed to generate a physical stimulation frequency drive adjustment plan corresponding to the improvement of lymphatic circulation cognition.

[0025] In an embodiment of the present invention, regression analysis is performed by utilizing the correlation between lymph flow velocity and EEG neural activity under physical stimulation mechanical vibration. First, the previously obtained lymph flow velocity data is used in combination with a multi-layer perceptron (MLP) algorithm to model the cognitive level of the EEG signal. The multi-layer perceptron is a deep learning network that can learn and extract the potential mapping relationship between lymph flow velocity and EEG cognitive level based on a large amount of input data. Through a large amount of training data, the model can automatically discover the nonlinear relationship between the two and calculate a mapping relationship model. The establishment of the model depends on the precise calibration and training of the data, and the representativeness and comprehensiveness of the data set must be ensured. After the mapping relationship is established, the ultrasonic stimulation frequency of the low-frequency pulse electromagnetic device can be finely adjusted based on the model, thereby optimizing the operating frequency of the device and achieving the best lymphatic circulation promotion effect and cognitive enhancement effect. In this process, the model will automatically adjust the stimulation frequency according to the influence of different frequencies on the flow velocity, thereby formulating a targeted physical stimulation frequency drive adjustment plan to achieve the optimal lymphatic circulation and cognitive enhancement effect.

[0027] As an embodiment of the present invention, refer to Figure 2 As shown, Figure 1 FIG. 1 is a functional flow chart of the physical stimulation frequency impact assessment module in FIG. 1 . In this embodiment, the physical stimulation frequency impact assessment module includes the following functions: S11: using a pressure sensor to monitor the stimulation pressure in real time during the physical stimulation driving process generated by the low-frequency pulse electromagnetic device to obtain the magnitude of the physical stimulation pressure; In an embodiment of the present invention, a high-precision pressure sensor is placed near the low-frequency pulse electromagnetic device to monitor the physical stimulation pressure generated by the device in real time. The pressure sensor uses a piezoelectric sensor that can effectively sense the changes in low-frequency pulses and has high sensitivity and response speed. When the low-frequency pulse electromagnetic device stimulates physical stimulation, the pressure sensor will capture the tiny pressure changes generated by the device during the driving process and convert it into an electrical signal for data acquisition. The electrical signal is output in real time through an analog-to-digital processing unit. The core of this step is to ensure that the pressure sensor has good sensitivity during the stimulation process, and can timely and accurately monitor the physical stimulation pressure generated by the low-frequency pulse electromagnetic device, and finally obtain the size of the physical stimulation pressure.

[0028] S12: Using a temperature sensor to monitor the stimulated skin temperature in real time during the physical stimulation driving process generated by the low-frequency pulse electromagnetic device to obtain the stimulated skin surface temperature; In an embodiment of the present invention, a temperature sensor is arranged near the stimulation area to monitor in real time the effect of the low-frequency pulse electromagnetic device driving process on the skin surface temperature. The selected temperature sensor is a thermocouple or an infrared sensor, which can accurately record the slight changes in the skin surface temperature during the stimulation process. The temperature sensor is arranged on the skin surface of the stimulation area, senses the temperature change through the thermosensitive material, and converts it into an electrical signal. After the signal is converted from analog to digital, it is transmitted to the data acquisition system for real-time monitoring. By real-time monitoring of the skin surface temperature during the stimulation process, the temperature stimulation caused by the device to the skin can be evaluated, and finally the stimulated skin surface temperature can be obtained.

[0029] S13: performing stimulation parameter cleaning processing on the physical stimulation pressure and the stimulation skin surface temperature, using a low-pass filter to remove high-frequency noise in the corresponding time sequence, and using a median filter algorithm to remove corresponding abnormal values, to obtain the stimulation pressure and skin surface temperature after preprocessing; In an embodiment of the present invention, the physical stimulation pressure and skin surface temperature data collected in real time are processed to remove existing high-frequency noise and outliers. First, the pressure and temperature data are filtered using a low-pass filter, and the cutoff frequency of the low-pass filter is set to be lower than the conventional noise frequency so as to effectively remove high-frequency noise in the data. The filtered data can smooth signal fluctuations and retain effective stimulation pressure and temperature change trends. Then, the processed data is further cleaned up using a median filtering algorithm. The median filtering removes outliers caused by sensor failure or external interference by sorting the data points and selecting the median. Through this step, the pressure and temperature data obtained will have higher accuracy, and finally the pre-processed stimulation pressure and skin surface temperature will be obtained.

In actual operation, the pressure data and the temperature data are first time-aligned so that the two data points are compared at the same time node. If the sampling frequencies of the two data are different, the low-frequency data are interpolated by an interpolation method to ensure consistent pressure and temperature values ​​at each time point. This process utilizes an interpolation algorithm, such as linear interpolation or spline interpolation, to ensure the accuracy of the synchronized data sequence, and ultimately obtains the corresponding stimulation pressure magnitude sequence and skin surface temperature sequence within the same time range.

[0031] S15: Based on the stimulation pressure magnitude sequence and the skin surface temperature sequence, the stimulation frequency influence evaluation is performed on the physical stimulation ultrasound corresponding to the low-frequency pulse electromagnetic device to obtain the pressure influence factor and the temperature influence factor corresponding to the ultrasound stimulation frequency.

[0032] In an embodiment of the present invention, the influence of the physical stimulation generated by the low-frequency pulse electromagnetic device on the ultrasonic frequency is evaluated by analyzing the synchronized stimulation pressure magnitude sequence and the skin surface temperature sequence. First, according to the experimental design, the pressure and temperature data are correlated and analyzed using a signal processing algorithm to evaluate the correlation between the stimulation pressure and the skin surface temperature. Then, according to the definitions of the pressure influencing factor and the temperature influencing factor, the influence of the ultrasonic stimulation frequency on the physical stimulation is calculated through numerical simulation or regression analysis. The pressure influencing factor characterizes the response degree of the pressure change to the ultrasonic frequency, and the temperature influencing factor characterizes the response degree of the skin surface temperature change to the ultrasonic frequency. Finally, based on the above calculation results, a quantitative relationship between the ultrasonic stimulation frequency and the pressure and temperature influences is formed, and finally the pressure influencing factor and the temperature influencing factor corresponding to the ultrasonic stimulation frequency are obtained.

[0033] Furthermore, the stimulation frequency impact assessment of the physical stimulation ultrasound waves corresponding to the low-frequency pulse electromagnetic device based on the stimulation pressure magnitude sequence and the skin surface temperature sequence includes: Conduct orthogonal experimental design of pressure and temperature for the stimulation pressure sequence and skin surface temperature sequence to generate different stimulation pressure and skin temperature combination conditions; In an embodiment of the present invention, by collecting relevant data of the stimulation pressure magnitude sequence and the skin surface temperature sequence, the stimulation pressure magnitude sequence is composed of multiple groups of different pressure values, including multiple pressure levels such as low, medium and high, and the skin surface temperature sequence is composed of different temperature points, covering multiple temperature values ​​from low to high temperature. By systematically designing these pressure values ​​and temperature values, an orthogonal experimental design framework is constructed, which can ensure that each combination condition is fully tested to achieve comprehensive coverage of the experimental effects. For example, by setting the pressure magnitude to 10, 20, 30, and 40 Pa, and the skin temperature to 28°C, 30°C, 32°C, and 34°C, these combination conditions of stimulation pressure and skin temperature are generated in combination with the orthogonal design scheme. This design will, based on the principle of orthogonal experiment, enable the experiment to minimize unnecessary repetitions, fully explore the influence of each variable (stimulation pressure and skin temperature) on the experimental results, and finally generate different stimulation pressure and skin temperature combination conditions.

During ultrasonic wave propagation, different degrees of energy attenuation will occur depending on the environment, such as stimulation pressure and skin temperature. Therefore, it is necessary to measure the energy attenuation of ultrasound waves under multiple pressure and temperature conditions. This process is usually carried out by using an energy detector to monitor the energy changes of ultrasound waves in real time.

Then, the energy distribution loss of the ultrasonic wave is recorded and analyzed under different temperature conditions using the mean and standard deviation of the skin temperature. By comparing the energy attenuation at different temperatures, the impact of temperature on the ultrasonic frequency distribution can be obtained. To this end, a temperature sensor can be used to measure the skin surface temperature under each set of experimental conditions, and the temperature value and the corresponding energy attenuation data are combined to evaluate the impact of temperature on the stimulation frequency through a mathematical model. Based on the relationship between the temperature data and the energy loss, the temperature impact factor is calculated, that is, the temperature impact factor = (energy loss attenuation rate under temperature conditions × frequency change amplitude) / frequency change density. This impact factor reveals the changing trend of the ultrasonic stimulation frequency under different temperature conditions, and finally the temperature impact factor corresponding to the ultrasonic stimulation frequency is obtained.

These devices sense the flow of the lymphatic ducts, measure the flow velocity and flow of the lymphatic fluid, and ensure the stability and accuracy of the signal. At the same time, the EEG nerve activity signal is collected by an electroencephalogram (EEG) device. The EEG device is placed on the surface of the scalp through an electrode array to record the EEG activity signal in real time. In order to ensure the high quality of the signal, the EEG device uses a high sampling rate to capture the tiny fluctuations of the EEG activity, and filters and processes the noise to ensure the reliability of the data in the subsequent analysis process, and finally obtains the lymphatic flow velocity and the EEG nerve activity signal.

First, the original EEG signal is decomposed into multiple scales using the discrete wavelet transform (DWT) method. The wavelet transform can effectively extract different frequency components in the signal, so that the EEG activities in different frequency bands can be analyzed. Specifically, the EEG signal is decomposed into multiple frequency bands of 0-4Hz, 4-8Hz, 8-13Hz, 13-30Hz and above 30Hz. Each frequency band represents a different type of neural activity in the brain, where low frequency bands (such as 0-4Hz) are associated with deep sleep and resting states, while high frequency bands (such as above 30Hz) are associated with cognitive activity states or concentration. Through this process, the original EEG signal is finely decomposed into multiple sub-signals, and finally the corresponding EEG activity sub-signals in different scale frequency bands are generated.

[0052] Preferably, time domain signal feature analysis is performed on the EEG activity sub-signals corresponding to different scale frequency bands to obtain the time domain features of the EEG signals corresponding to different scale frequency bands, including the mean, variance and peak value; In an embodiment of the present invention, the time domain signal characteristics of the EEG activity sub-signal of each frequency band are first calculated.

Specifically, statistical analysis methods, such as Pearson correlation analysis, regression analysis, etc., are used to analyze the correlation between EEG signal features of different frequency bands (such as mean, variance and peak) and known cognitive activities. For example, low-frequency signals (such as 0-4Hz) are correlated with cognitive activities in resting states and deep sleep; high-frequency signals (such as above 30Hz) are correlated with cognitive activities with high cognitive load or focused attention. These analyses help establish a mapping relationship between EEG signals of different frequency bands and neural cognitive activities, further revealing the role of EEG activities of different frequency bands in different cognitive states, thereby obtaining a cognitive role mapping relationship between EEG signals of different frequency bands and neural cognitive activities. At the same time, based on the previously obtained cognitive function mapping relationship, the subjects' EEG activities are comprehensively analyzed to evaluate their neurocognitive level.

First, a vibration stimulation device (such as an adjustable frequency vibrator) is used to perform mechanical vibration stimulation around the lymphatic duct to simulate the influence of the physical vibration effect on the lymph flow rate. Then, the change of the lymph flow rate under different vibration frequencies is recorded. By collecting the flow rate data under vibration stimulation, the data is analyzed using a nonlinear regression fitting method.

For lymph at different flow rates, the electroencephalograph will record the corresponding EEG signal, and perform a detailed analysis of the frequency distribution and amplitude of the signal, so as to identify the EEG characteristic changes at different flow rates by filtering the EEG signal, power spectral density analysis, waveform analysis, etc., and compare it with the changes in cognitive level, so as to obtain a frequency distribution and amplitude change feature database of EEG cognitive level at different lymph flow rates. The key to this analysis process is to collect clear and accurate EEG signals, and use advanced signal processing technology to extract relevant features, and finally obtain the characteristic changes corresponding to the EEG cognitive level at different lymph flow rates, including frequency distribution and amplitude.

In the specific operation, each set of data is first standardized to convert the EEG cognitive characteristics under different flow rates into a unified and comparable scale. Then, based on the data set, a linear regression model is performed on the relationship between the lymph flow rate and the EEG cognitive level. A linear regression mathematical model between the lymph flow rate and the EEG cognitive level is established by regression analysis methods such as the least squares method. The parameters in the regression equation can reflect the degree and direction of the influence of the flow rate change on the cognitive level.

First, the features obtained in the linear regression analysis are used as input features, and the changes in EEG cognitive level are used as output labels. These data are learned by training a multi-layer perceptron network to form an association mapping model between lymph flow rate and EEG cognitive level. Specifically, the network continuously adjusts weights and biases through feedforward and back propagation mechanisms to minimize prediction errors. During the training process, different input features and output labels undergo complex nonlinear transformations through multiple hidden layers, so that the model can capture the complex relationship between flow rate and cognition. Through this step, an accurate mapping relationship is obtained, which can effectively predict the changes in EEG cognitive level under different lymph flow rates, and finally obtain the association mapping relationship between lymph flow rate and EEG cognitive level.

[0060] Preferably, the stimulation frequency drive adjustment of the physical stimulation ultrasound waves corresponding to the low-frequency pulse electromagnetic device is performed based on the correlation mapping relationship between the lymph flow rate and the EEG cognitive level to generate a physical stimulation frequency drive adjustment scheme corresponding to the lymphatic circulation cognitive improvement.

[0061] In an embodiment of the present invention, a driving adjustment scheme for the physical stimulation frequency is designed based on the previously obtained correlation mapping relationship between the lymph flow rate and the EEG cognitive level. In this process, first, according to different flow rate conditions, the stimulation frequency and intensity parameters are input into the physical stimulation ultrasonic device, and the body is mechanically stimulated by the ultrasonic device to adjust the lymph flow rate. When the EEG cognitive level improves slowly, the adjustment scheme for the stimulation frequency and intensity is determined according to the correlation mapping relationship, and the stimulation intensity and duration of a specific frequency are gradually increased to enhance the lymph flow rate and promote the improvement of the EEG cognitive level. Conversely, when the EEG cognitive level improves too quickly, the physical stimulation device is automatically adjusted by the system to reduce the stimulation frequency and intensity to avoid adverse reactions caused by excessive flow rate, thereby maintaining a stable growth in the cognitive level through appropriate stimulation adjustment, accurately controlling the stimulation mode of the ultrasonic device, and adjusting the stimulation frequency and intensity in real time according to the feedback signal to achieve the best cognitive improvement effect, and finally generating a physical stimulation frequency driving adjustment scheme corresponding to the lymphatic circulation cognitive improvement.

[0062] Furthermore, the physical stimulation frequency driving adjustment scheme corresponding to the lymphatic circulation cognition improvement is specifically as follows: when the EEG cognitive level improves slowly at the corresponding lymph flow rate, the stimulation frequency change pattern corresponding to the physical stimulation ultrasound at the lymph flow rate is driven to increase the stimulation intensity and duration of the specific stimulation frequency, so as to promote the lymph flow rate and thereby improve the EEG cognitive level; when the EEG cognitive level improves too quickly at the corresponding lymph flow rate, the stimulation frequency change pattern corresponding to the physical stimulation ultrasound at the lymph flow rate is driven to reduce the stimulation intensity and duration of the specific stimulation frequency, so as to slow down the lymph flow rate and thereby lower the EEG cognitive level.
