[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0043] Example 1

[0044] Figure 1 This is a block diagram of an acupoint positioning system according to an embodiment of this application.

[0045] like Figure 1 As shown, the acupoint positioning system provided in this embodiment is used to help doctors or other personnel to accurately locate acupoints on the examinee. The acupoint positioning system includes a controller 10, a signal acquisition device 20, a human stimulation device 30, and a position indicator device 40.

[0046] When this system is used to precisely locate acupoints on a subject, the corresponding device in this embodiment needs to be placed on the subject's body. For example, the signal acquisition device needs to be placed on the subject's head, and the human stimulation device needs to be placed in the area of ​​the target acupoint selected through coarse localization. This area is a certain area covering the target acupoint, and its area will certainly be larger than the area of ​​the acupoint itself. This coarse localization can be determined based on the user's medical knowledge through traditional methods, or it can be based on pre-marked acupoints on a three-dimensional human body model. The target acupoint here refers to the acupoint to be located in this localization process.

[0047] This signal acquisition device is used to acquire the electroencephalogram (EEG) signals of the subject, and specifically includes multiple electrodes connected to the controller, such as... Figure 2 As shown. It includes 19 recording electrodes (excluding FPz and Oz) and 2 reference electrodes, as... Figure 1As shown. Each electrode name begins with a letter indicating the electrode region (Fp = frontal; F = frontal; C = central; P = vertex; O = occipital; T = temporal). The electrode name is followed by a number or letter indicating its distance from the center, with odd numbers for the left hemisphere and even numbers for the right hemisphere. Larger numbers indicate greater distance from the midline. The midline position is marked with "z" to represent the number 0 to distinguish it from the letter O.

[0048] During EEG signal acquisition, the mastoid electrodes (A1 and A2) on both ears were used as reference electrodes, and the impedance values ​​of all electrodes were kept below 10 kΩ. The sampling rate of the experimental acquisition system was 512 Hz, and the bandpass filter ranged from 0.5 Hz to 49 Hz. Furthermore, to facilitate further analysis of pain signal activity in different brain regions and the coherence between these regions in subsequent studies, EEG data were acquired from 19 electrodes covering all brain regions.

[0049] This human stimulation device is used to apply corresponding stimulation to the area where the target acupoints of the subject are located. The stimulation can be applied by pressing with the corresponding actuator. In order to ensure positioning accuracy, the application point of each stimulation should be as small as possible.

[0050] The controller is used to output stimulation control signals to the human stimulation device. These stimulation control signals are used to control the execution components of the human stimulation device to apply stimulation to the target acupoints point by point. At this time, the brain signals are continuously acquired through the aforementioned brain signal acquisition device and processed to determine the pain state reflected by the brain signals. When the pain state when stimulating a certain point exceeds the pain state when stimulating other points, the point is determined to be the acupoint location of the target acupoint.

[0051] When the controller determines the location of an acupoint, it directs the location indicator device to point the acupoint to the user. This can be done by projecting a light onto the acupoint or by positioning the actuator of the human stimulation device at the acupoint and obtaining a pointer pointing to the acupoint. This achieves precise positioning of the target acupoint.

[0052] As can be seen from the above technical solution, this embodiment provides an acupoint location system, including a controller and a signal acquisition device, a human stimulation device, and a location indicator device, all connected to the controller. The electroencephalogram (EEG) signal acquisition device is placed on the subject's head to collect the subject's EEG signals; the human stimulation device, under the control of the controller, applies stimulation to different points in the area where the target acupoint is located; the controller processes the EEG signals and determines the acupoint location in the area based on the principle of pain perception; the location indicator device indicates the acupoint location to the user. The solution in this application is based on the fact that acupoints produce more pronounced pain when pressed compared to other locations, thus achieving precise location. Compared to traditional acupoint location methods, this solution achieves more accurate acupoint location.

[0053] Example 2

[0054] Figure 3 This is a flowchart of a positioning control method according to an embodiment of this application.

[0055] like Figure 3 As shown, the positioning control method provided in this embodiment is applied to the acupoint positioning system of the previous embodiment. Specifically, it is applied to the controller in the acupoint positioning system. The controller can be understood as a computer, server, or embedded device with data computing and information processing capabilities. The positioning control method includes the following steps:

[0056] S1. Continuously receive the subject's EEG signals.

[0057] That is, when the above system is turned on, it begins to acquire the EEG signals collected by the above signal acquisition device. Before the subject is stimulated, that is, when the subject is in a resting state, the EEG signals collected are the first signals, which are used as the basis for comparison of subsequent EEG signals; when the subject is stimulated, the EEG signals collected are the second signals.

[0058] S2. Apply stimulation to the area where the target acupoint is located.

[0059] That is, by outputting corresponding stimulation control commands to the aforementioned human stimulation device, the device applies stimulation to the target acupoint area of ​​the human body. The specific process is as follows:

[0060] First, the target acupoint is roughly located based on the three-dimensional model of the human body to obtain the area where the target acupoint is located. Alternatively, the area can be determined according to the traditional acupoint location method. Since it only determines the approximate location of the acupoint, the traditional location method is sufficient.

[0061] The three-dimensional human body model here refers to a mathematical model obtained by training the model based on the acupoints pre-marked on the human body model, which is able to coarsely locate the acupoints on the human body.

[0062] Then, the human stimulation device is driven to stimulate the above-mentioned areas point by point. Point-by-point stimulation enables the signal acquisition device to collect the electroencephalogram (EEG) signal when each point is stimulated. The EEG signal reflects the changes in the brain's electrical activity after the human body receives stimulation.

[0063] S3. Process the EEG signal to obtain the acupoint location of the target acupoint.

[0064] Previous studies have shown that the main brain regions responding to pain-induced EEG signals are the frontal, central, and parietal regions. After pain stimulation, the amplitude of EEG signals in the prefrontal cortex tends to increase in the delta (1–4 Hz), theta (4–8 Hz), and beta (13–30 Hz) bands; the amplitude changes in the alpha (8–13 Hz) band show different trends. With increasing pain intensity, both information flow and connectivity in the frontal lobe increase. Based on the above analysis, the EEG signals are processed as follows:

[0065] First, using the first signal as a baseline, the second signal is compared with the first signal. If the EEG signal changes significantly when the target acupoint is pressed, specifically, the amplitudes of the delta, theta, and beta bands show an upward trend.

[0066] Then, when the above amplitude is found to be on the rise, the point of stimulation currently received by the examinee is determined to be the acupoint location.

[0067] S4. Indicate the location of the acupoint to the user.

[0068] Specifically, by issuing control commands to the aforementioned location indicator device, it can indicate the location of the acupoint to the user, thereby achieving precise positioning of the acupoint.

[0069] The above scheme enables the acupoint positioning system to accurately locate acupoints based on the principle of pain perception.

[0074] Example 3

[0075] Figure 4 This is a block diagram of a positioning control device according to an embodiment of this application.

[0076] like Figure 4 As shown, the positioning control device provided in this embodiment is applied to the acupoint positioning system of the previous embodiment. Specifically, it is applied to the controller in the acupoint positioning system. The controller can be understood as a computer, server, or embedded device with data computing and information processing capabilities. The positioning control device includes a signal acquisition module 101, a stimulation control module 102, an acupoint positioning module 103, and an acupoint indication module 104.

[0077] This signal acquisition module is used to continuously receive the subject's electroencephalogram (EEG) signals.

[0078] That is, when the above system is turned on, it begins to acquire the EEG signals collected by the above signal acquisition device. Before the subject is stimulated, that is, when the subject is in a resting state, the EEG signals collected are the first signals, which are used as the basis for comparison of subsequent EEG signals; when the subject is stimulated, the EEG signals collected are the second signals.

[0079] This stimulation control module is used to apply stimulation to the area where the target acupoint is located.

[0080] That is, by outputting corresponding stimulation control commands to the aforementioned human stimulation device, the human stimulation device applies stimulation to the area where the target acupoint is located. Specifically, the stimulation control module includes a coarse positioning unit 1021 and a stimulation execution unit 1022, such as... Figure 5 As shown.

[0081] The coarse positioning unit is used to coarsely locate the target acupoint based on the three-dimensional human body model to obtain the area where the target acupoint is located. Alternatively, the area can be determined according to the traditional acupoint positioning method. Since it only determines the approximate location of the acupoint, the traditional positioning method can fully meet the requirements.

[0082] The three-dimensional human body model here refers to a mathematical model obtained by training the model based on the acupoints pre-marked on the human body model, which is able to coarsely locate the acupoints on the human body.

[0083] The stimulation execution unit is used to drive the human stimulation device to stimulate the above-mentioned areas point by point. Point-by-point stimulation enables the signal acquisition device to collect the electroencephalogram (EEG) signal when each point is stimulated. The EEG signal reflects the changes in the brain's electrical activity after the human body is stimulated.

[0084] The acupoint location module is used to process electroencephalogram (EEG) signals to obtain the acupoint location of the target acupoint.

[0085] Previous studies have shown that the main brain regions responding to pain-induced EEG signals are the frontal, central, and parietal regions. After pain stimulation, the amplitude of the frontal EEG signal tends to increase in the delta (1–4 Hz), theta (4–8 Hz), and beta (13–30 Hz) bands; the amplitude changes in the alpha (8–13 Hz) band are not uniform. With increasing pain intensity, both information flow and connectivity in the frontal lobe increase. Based on the above analysis, this acupoint localization module includes a signal comparison unit 1031 and a localization execution unit 1032.

[0086] The signal comparison unit is used to compare the second signal with the first signal, using the first signal as a baseline. If the target acupoint is pressed, the EEG signal will change significantly, specifically the amplitude of the delta, theta, and beta bands will show an upward trend.

[0087] The positioning execution unit is used to determine the acupoint location of the subject when the above amplitude shows an upward trend.

[0088] The acupoint indicator module is used to indicate the location of the acupoint to the user.

[0089] Specifically, by issuing control commands to the aforementioned location indicator device, it can indicate the location of the acupoint to the user, thereby achieving precise positioning of the acupoint.

[0090] The above-mentioned device enables the acupoint positioning system to accurately locate acupoints based on the principle of pain perception.

The name of a unit does not necessarily limit the unit itself; for example, the first acquisition unit can also be described as "a unit that acquires at least two Internet Protocol addresses".
