Description

Technical Field

[0001] The present invention relates to the technical field of acupoint stimulators, and in particular to an acupoint stimulator capable of intelligently determining acupoints and performing real-time intervention based on acupoint electrical characteristics. Background Art

[0002] In acupuncture clinical practice, acupoint positioning, as the core of intervention, is particularly important. The effectiveness of acupuncture treatment in clinical practice is closely related to whether the physician has rich experience and whether he uses acupoints accurately and accurately locates acupoints. The clinical efficacy of acupuncture has extremely strict requirements for acupoint positioning. How to accurately analyze the relationship between acupoints and diseases and enable them to be effectively applied clinically and obtain effectiveness is a key step. The acupoint information provided by the instruments on the market is not very targeted. Whether it is a rough schematic diagram or acupoint positioning described by professional medicine, it requires professional knowledge and experienced doctors to operate. Therefore, the acupoint information output by the therapeutic instruments on the market is less targeted and less feasible.

[0003] In addition, "Three Causes and Treatment" is one of the main pillars of the TCM diagnosis and treatment system, and has played a pivotal role in clinical practice for more than 2,000 years. Among them, "Treatment according to individual characteristics" means that treatment measures should be formulated according to the individual characteristics of the patient. This is the embodiment of the holistic concept and syndrome differentiation in TCM.

[0004] At present, the research on acupoint sensitization believes that acupoints are not a fixed and isolated point distribution, but a domain whose size and position can change under the disease state, showing a dynamic process from "resting state" to "sensitized state". The application value of electrical sensitivity - the electrical characteristics of acupoints in the field of acupuncture research has been preliminarily confirmed. There is evidence that the conductivity characteristics of the twelve well points in sub-healthy people are significantly different from those in healthy people; the conductivity of the original points of patients with insomnia and anxiety and primary dysmenorrhea are unbalanced. In other words, the electrical signals of the body surface meridian points of the human body will be different under the disease state. Therefore, the electrical signals of meridian points are a good indicator of the distribution of acupoints on the body surface, and are considered to be the external reflection of the disease on the body surface, which can reflect the individual's current physiological and pathological state in real time and sensitively.

[0005] However, in actual clinical acupuncture, there are no instruments and equipment related to the above research content, and the existing acupuncture treatment instruments cannot output the intervention site in an individualized, targeted, and dynamic manner, which affects the treatment effect of acupuncture.

[0006] Therefore, it is necessary to invent an acupoint stimulator with intelligent acupoint location and real-time intervention based on acupoint electrical characteristics to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide an acupoint stimulator for intelligent acupoint determination and real-time intervention based on acupoint electrical characteristics. The collected electrical signals are analyzed by using the correlation dimension analysis system in the signal processing system, and the noise-reduced data is processed using the correlation dimension. The computer sends a signal to the control terminal, and the control terminal intelligently generates a trigger signal to the output electrode, selectively outputs warm-colored areas (areas with high information content, complexity and uncertainty), and performs targeted, specific and targeted surface treatment to solve the above-mentioned deficiencies in the technology.

[0008] In order to achieve the above-mentioned object, the present invention provides the following technical solutions: an acupoint stimulator for intelligent acupoint determination and real-time intervention based on acupoint electrical characteristics, comprising an acupoint electrical signal acquisition system for acquiring human electrical signals, a signal processing system for processing the acquired electrical signals, and an output system for outputting electrical stimulation;

[0009] The acupuncture point electrical signal acquisition system and output system include the same control terminal and electrode patch, the connection end of the electrode patch is connected to the control terminal, the electrode patch is provided with an input electrode for collecting signals and an output electrode for outputting electrical stimulation, and the output electrodes and the input electrodes are alternately arranged in rows;

[0010] The signal processing system includes a computer equipped with a correlation dimension analysis system, wherein the connection end of the computer is connected to the connection end of the control terminal, wherein the correlation dimension analysis system can eliminate useless information from the outside and the human body itself, and extract the comprehensive bioelectric signal characteristics of the body surface in response to remote stimulation.

[0011] Preferably, the input electrodes and the output electrodes are both silver chloride point electrodes, and the number of the silver chloride point electrodes is 130, the distance between each silver chloride point electrode is 5 mm, and the number of the input electrodes and the output electrodes is equal.

[0012] Preferably, the electrode patch is powered by a battery.

[0013] Preferably, the analysis system uses correlation dimension to process the denoised data. Correlation dimension is an important method for solving embedding dimension in the phase space reconstruction process. The lower the value of correlation dimension, the higher the sequence self-similarity; the larger the value of correlation dimension, the more complex the sample sequence. At present, correlation dimension is used in evaluating the complexity of physiological time series (EEG, sEMG, etc.) and diagnosing pathological conditions.

[0014] The specific algorithm is as follows:

[0015] If there is a one-dimensional time series {x1, x2, ..., xn}, its phase space reconstruction is obtained to obtain a series of vectors in the high-dimensional phase space:

[0016] x i (τ,m)=(x i ,x i ,…,x i + (m-1)τ )

[0017] Where: τ is the time delay, τ = kΔt, where k is an integer and Δt is the sampling time interval; m is the embedding dimension; i = 1, 2, ..., N; N is the number of reconstructed vectors, N = n-(m-1)τ;

[0018] The correlation dimension of the reconstructed phase space is:

[0019]

[0020] Where: j≠k; r is the radius of the m-dimensional hypersphere; H is the Heaviside function.

[0021] Preferably, the input electrode is a signal collection electrode, the output electrode is used for transcutaneous electrical stimulation of acupoints, and the electrode patch is composed of a flexible circuit board, an input electrode and an output electrode.

[0022] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0023] 1. By using input electrodes to collect electrical signals from human meridian points, biofeedback based on electrical signals from meridian points on the human body surface is obtained. According to the individual state, the corresponding output position (including size) is output using output electrodes. It can be used in hospitals, institutions, or personal homes. The present invention expands the clinical treatment methods of acupuncture instruments, and for the first time introduces the latest research technologies and methods based on modern biomedicine into traditional acupuncture treatment clinics, realizing the organic integration of the two, thereby solving the difficulty of traditional acupoint therapeutic instruments without individualized, targeted, and dynamic output intervention positions, thereby improving the clinical efficacy of acupuncture intervention;

[0024] 2. The collected electrical signals are analyzed by using the correlation dimension analysis system in the signal processing system, and the noise-reduced data is processed using the correlation dimension. The larger the correlation dimension value, the higher the information content, complexity and uncertainty of the system. The results show that the image appears in warm tones. On the contrary, when the correlation dimension value is smaller, the system is more stable, the complexity is lower, and the image appears in cold tones. The computer sends a signal to the control terminal, and the control terminal intelligently generates a trigger signal to the output electrode, selectively outputting the warm-colored area - the area with high information content, complexity and uncertainty, for targeted, specific and targeted surface treatment, thereby realizing an individualized "diagnosis-intervention" intervention treatment device.

Based on the analysis results, signals are sent to the output system to perform corresponding acupoint stimulation.

[0033] Specifically, Figure 2 As shown, the acupuncture point electrical signal acquisition system and output system include the same control terminal and electrode patch, the connection end of the electrode patch is connected to the control terminal, the electrode patch is provided with an input electrode for collecting signals and an output electrode for outputting electrical stimulation, and the output electrodes and the input electrodes are alternately arranged in rows;

[0034] Moreover, if Figure 3As shown, the input electrode and the output electrode are both silver chloride point electrodes, and the number of silver chloride point electrodes is 130, the distance between each silver chloride point electrode is 5 mm, the number of the input electrode and the output electrode is equal, the input electrode and the output electrode arranged in this way have good sensitivity, accuracy, stability, and noise resistance, and can meet the requirements of measuring area and measuring time synchronization by continuously collecting the potential (electric potential) in the body surface area, and can also take into account the two functions of collecting signals and outputting stimulation. The input electrode is a signal collection electrode, and the output electrode is used for transcutaneous acupoint electrical stimulation. The electrode patch is composed of a flexible circuit board, an input electrode and an output electrode, as shown Figure 4 As shown, from left to right, the electrode patch includes a flexible circuit board, an input electrode and an output electrode.

[0035] In addition, the electrode patch is battery-powered, and the battery powers the input electrode and the front end of the output electrode to ensure good signal quality (noise is less than 10μVpp), and double-layer flexible printing is performed so that the wires are located on the back to reduce crosstalk.

[0036] The signal processing system includes a computer equipped with a correlation dimension analysis system, the connection end of the computer is connected to the connection end of the control terminal, and the analysis system uses correlation dimension to process the denoised data, and the correlation dimension is used as a value to quantify the regularity and complexity of the time series; the specific algorithm is as follows: if there is a one-dimensional time series {x1, x2, ..., xn}, its phase space is reconstructed to obtain a series of vectors in the high-dimensional phase space:

[0037] x i (τ,m)=(x i ,x i ,…,x i + (m-1)τ )

[0038] Where: τ is the time delay, τ = kΔt, where k is an integer and Δt is the sampling time interval; m is the embedding dimension; i = 1, 2, ..., N; N is the number of reconstructed vectors, N = n-(m-1)τ;

The computer sends a signal to the control terminal, and the control terminal intelligently generates a trigger signal to the output electrode, selectively outputting the warm color area - the part with high information content, complexity and uncertainty, to carry out targeted, specific and targeted body surface treatment, thereby realizing an individualized "diagnosis-intervention" intervention treatment device.
