Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a transcutaneous electrical stimulation device and its application method. Background Technology

[0002] Acupuncture has a history of over 2,000 years in China. Traditional Chinese medicine acupuncture is a collective term for needling and moxibustion. Needling involves inserting filiform needles into specific acupoints on the patient's body and using techniques such as twisting and lifting to stimulate specific parts of the body, thereby achieving the purpose of treating diseases.

[0003] Traditional acupuncture requires specialized personnel and is not suitable for widespread application. Transcutaneous electrical nerve stimulation (TENS) is an electrotherapy method that treats pain by delivering specific low-frequency pulsed currents through the skin. Its combination with traditional Chinese acupuncture forms electroacupuncture. Electroacupuncture significantly changes this situation. It eliminates the need for acupuncture needles, using electronic pulses to stimulate acupoints and stimulate nerves. Electroacupuncture is easy to perform, safe, and provides accurate and reliable results. It can replace manual acupuncture for extended periods, saving manpower.

Figure 2 This is a top view of the transcutaneous electrical stimulation device. Figure 3 This is a left view of the transcutaneous electrical stimulation device. (Example) Figures 1 to 3 As shown, the device includes: a control module 1, an electrical stimulation controller 2, and an electrical stimulation matrix module 3 connected to the electrical stimulation controller 2; the electrical stimulation controller 2 and the electrical stimulation matrix module 3 appear in pairs and correspond one-to-one.

[0071] Please refer to the example below. Figure 4 The top view of the electrical stimulation matrix module shown shows that each electrical stimulation matrix module 3 includes multiple electrical contacts 31; the electrical contacts 31 are adapted to contact the target stimuli 4 to provide electrical stimulation to the target stimuli 4; each electrical stimulation controller 2 is connected to the control module 1 through an elastic frame 5; the elastic frame 5 is adapted to fix the control module 1 to the target stimuli 4.

[0072] The control module 1 is used for:

[0073] Based on the state information of the electrical contacts 31 of each electrical stimulation matrix module 3 and the angle state information of the elastic frame 5, a three-dimensional model of the target stimulus 4 is obtained.

[0074] According to the target acupoint selection rules, the coordinate positions of each acupoint corresponding to each electrical stimulation matrix module 3 are determined on the three-dimensional model of the target stimulus 4.

[0075] Based on the target electrical stimulation prescription and the coordinate positions of the electrical stimulation matrix modules 3 corresponding to each acupoint, a three-dimensional discharge field matrix of each electrical stimulation matrix module 3 is generated.

[0076] Based on the three-dimensional discharge field matrix of each electrical stimulation matrix module 3, each electrical stimulation matrix module 3 is controlled to perform the stimulation operation specified in the target electrical stimulation prescription.

[0077] For example, the control module 1 is a rigid shell, which is connected to each electrical stimulation controller 2 through an elastic frame 5 material. Each electrical stimulation controller 2 and the electrical stimulation matrix module 3 are rigidly fixed using a circuit board interface and screws.

[0078] Furthermore, the control module 1 has a communication control relationship with each electrical stimulation controller 2. When the control module 1 and each electrical stimulation controller 2 are wired, they can also have a power supply relationship, that is, the control module 1 supplies power to each electrical stimulation controller 2.

[0079] Furthermore, each electrical stimulation controller 2 can cover the target stimuli 4. For example, the target stimuli 4 can be the top and back of the head, the area along the line connecting the top of the head and the temples, the area above and below the ears, the philtrum area, and the area below the chin.

[0080] Furthermore, the target stimulus 4 can also be a part of the body such as the limbs, and each electrical stimulation controller 2 and the electrical stimulation matrix module 3 can also be connected to the control module 1 by flexible cables and fixed to the limbs or other parts of the body by elastic cable ties, tape or other materials.

[0081] Furthermore, the control module 1 is connected to the electrical stimulation controller 2 on the head via a wired connection, while the electrical stimulation controllers 2 on other parts of the body are connected via Wi-Fi. One control module 1 can connect to multiple electrical stimulation controllers 2 simultaneously, and each electrical stimulation controller 2 has a unique number in the control module 1.

[0082] In one possible implementation, please refer to, for example... Figure 5 The diagram shows the structure of the electrical stimulation matrix module 3. The electrical stimulation matrix module 3 includes a matrix digital filter 32, and each electrical contact 31 on the electrical stimulation matrix module 3 corresponds one-to-one with the matrix of the matrix digital filter 32.

[0083] Furthermore, the bottom of the electrical stimulation matrix module is also provided with a current input terminal 33, which is used to introduce electrical energy from the current input terminal 33 to each electrical contact 31 on the electrical stimulation matrix module 3.

[0084] In one possible implementation, please refer to, for example... Figure 6 The schematic diagram of the structure of the electrical contacts shown includes a spring solenoid valve 301 and a metal contact 302 controlled by the spring solenoid valve 301.

[0085] The spring solenoid valve 301 and the metal contact 302 appear in pairs and correspond one-to-one. They are used to receive the control signal and electrical stimulation current of the corresponding electrical stimulation controller 2 and to feed back the spring compression signal.

[0086] Furthermore, the electrical contact 31 also includes a solenoid valve switch 303 and an electrical stimulation current circuit 304. The solenoid valve switch 303 is used to control the opening and closing of the spring solenoid valve 301; the electrical stimulation current circuit 304 is used to perform circuit control on the metal contact 302 to perform electrical stimulation.

[0087] In one possible implementation, the elastic frame 5 is made of a stainless steel plate with an elastic rotatable structure; a sensor is provided at the elastic rotatable structure to monitor the rotation angle of the elastic frame 5. The elastic frame 5 itself is made of a rigid material.

[0088] In one possible implementation, the device further includes a flexible buffer backplate 6; the flexible buffer backplate 6 is fixed together with the control module.

[0089] Furthermore, the flexible cushioning backplate 6 is made of foam material.

[0090] In summary, the transcutaneous electrical stimulation device includes a control module, an electrical stimulation controller, and an electrical stimulation matrix module connected to the electrical stimulation controller. The electrical stimulation controller and the electrical stimulation matrix module appear in pairs and correspond one-to-one. Each electrical stimulation matrix module includes multiple electrical contacts. The electrical contacts are adapted to contact the target stimuli to provide electrical stimulation to the target stimuli. Each electrical stimulation controller is connected to the control module via an elastic frame. The elastic frame is adapted to fix the control module 1 onto the target stimuli. This transcutaneous electrical stimulation device can realize the modernization, digitalization, and intelligence of multi-point precise automatic acupuncture, improving the convenience and standardization of operation compared to traditional acupuncture methods.

[0091] Figure 7 This is a flowchart illustrating a method for applying a transcutaneous electrical stimulation device according to an exemplary embodiment. This application method is used in, for example... Figures 1 to 3 In the control module 1 of the transcutaneous electrical stimulation device shown, the device further includes an electrical stimulation controller and an electrical stimulation matrix module connected to the electrical stimulation controller; the electrical stimulation controller and the electrical stimulation matrix module appear in pairs and correspond one-to-one.

[0092] Each of the electrical stimulation dot matrix modules includes multiple electrical contacts; the electrical contacts are adapted to contact a target stimuli to provide electrical stimulation to the target stimuli; each of the electrical stimulation controllers is connected to the control module via an elastic frame; the elastic frame is adapted to fix the control module to the target stimuli;

[0093] like Figure 7 As shown, the application method may include the following steps:

[0094] S701. Based on the electrical contact status information of each electrical stimulation matrix module and the angle status information of the elastic frame, obtain a three-dimensional model of the target stimulus.

[0095] In one possible implementation, when using the transcutaneous electrical stimulation device to stimulate the target stimulus, the control module in the transcutaneous electrical stimulation device calculates the coordinates of the electrical contacts of each electrical stimulation matrix module in three-dimensional virtual space based on the offset of the electrical contacts corresponding to each electrical stimulation matrix module relative to the initial angle and the rotation angle of each elastic frame relative to the initial position, thereby constructing a three-dimensional model of the target stimulus.

[0096] For example, the angle state information may include size information, rotatable angle, and initial angle.

[0097] S702. According to the target acupoint selection rules, determine the coordinate positions of each acupoint corresponding to each electrical stimulation matrix module on the three-dimensional model of the target stimulus.

[0098] In one possible implementation, after constructing a three-dimensional model of the target stimulus, the position of each acupoint on the three-dimensional model can be calculated according to the target acupoint selection rules, and the position of each acupoint can be transformed to each point in the lattice coordinate system corresponding to each electrical stimulation lattice module, thereby obtaining the coordinate position of all acupoints on each electrical stimulation lattice module.

[0099] Furthermore, the acupoint selection rules can be the common acupoint selection principles in acupuncture, mainly including local acupoint selection, distal acupoint selection, syndrome differentiation acupoint selection, and symptom-based acupoint selection.

[0100] S703. Based on the target electrical stimulation prescription and the coordinate positions of the electrical stimulation matrix modules corresponding to each acupoint, generate a three-dimensional discharge field matrix for each electrical stimulation matrix module.

[0101] For example, the target electrostimulation prescription may include the stimulation angle, depth, frequency, axial rotation, and duration of each acupoint. Therefore, after determining the coordinate positions of each acupoint corresponding to each electrostimulation matrix module on the three-dimensional model of the target stimuli, if the stimulation operation specified by the target electrostimulation prescription is to be performed, each acupoint must be located on the three-dimensional model of the target stimuli according to the coordinate positions of each acupoint corresponding to each electrostimulation matrix module. Based on the prescription information of the target electrostimulation prescription, the three-dimensional discharge field matrix of the electrostimulation matrix module corresponding to each acupoint is calculated. The three-dimensional discharge field matrix may be the discharge duration, discharge waveform, angle, frequency, etc. of the electrical contact at the corresponding acupoint.

[0102] S704. Based on the three-dimensional discharge field matrix of each electrical stimulation matrix module, control each electrical stimulation matrix module to execute the stimulation operation specified in the target electrical stimulation prescription.

[0103] In one possible implementation, after obtaining the three-dimensional discharge field matrix of each electrical stimulation matrix module, each acupoint is stimulated through the electrical contacts of the electrical stimulation matrix module corresponding to each acupoint, thereby realizing the stimulation operation specified in the target electrical stimulation prescription. Furthermore, during stimulation, one electrical stimulation matrix module can correspond to not only one acupoint but also multiple acupoints. The specific correspondence can be planned according to the target electrical stimulation prescription and the target acupoint selection rules.

[0104] In summary, firstly, a three-dimensional model of the target stimulus is obtained based on the electrical contact state information of each electrical stimulation matrix module and the angle state information of the elastic frame; then, according to the target acupoint selection rules, the coordinate positions of each acupoint corresponding to each electrical stimulation matrix module are determined on the three-dimensional model of the target stimulus; next, based on the target electrical stimulation prescription and the coordinate positions of the electrical stimulation matrix modules corresponding to each acupoint, a three-dimensional discharge field matrix of each electrical stimulation matrix module is generated; finally, based on the three-dimensional discharge field matrix of each electrical stimulation matrix module, each electrical stimulation matrix module is controlled to execute the stimulation operation specified in the target electrical stimulation prescription. The above scheme can realize the modernization, digitalization, and intelligence of multi-point precise automatic acupuncture, and improves the convenience and standardization of operation compared with traditional acupuncture methods.

[0105] Figure 8 This is a flowchart illustrating a method for applying a transcutaneous electrical stimulation device according to an exemplary embodiment. This application method is used in, for example... Figures 1 to 3 In the control module 1 of the transcutaneous electrical stimulation device shown, the device further includes an electrical stimulation controller and an electrical stimulation matrix module connected to the electrical stimulation controller; the electrical stimulation controller and the electrical stimulation matrix module appear in pairs and correspond one-to-one.

[0106] Each of the electrical stimulation dot matrix modules includes multiple electrical contacts; the electrical contacts are adapted to contact a target stimuli to provide electrical stimulation to the target stimuli; each of the electrical stimulation controllers is connected to the control module via an elastic frame; the elastic frame is adapted to fix the control module to the target stimuli;

[0107] like Figure 8 As shown, the application method may include the following steps:

[0108] S801. Based on the electrical contact status information of each electrical stimulation matrix module and the angle status information of the elastic frame, obtain a three-dimensional model of the target stimulus.

[0109] In one possible implementation, based on the initial state information of each electrical stimulation matrix module and the initial angle information of each elastic frame, the three-dimensional coordinates of each electrical contact on each electrical stimulation matrix module are obtained to construct an initial three-dimensional model.

[0110] Based on the offset of the spring solenoid valve corresponding to each electrical stimulation dot matrix module relative to the initial angle and the rotation angle of each elastic frame relative to the initial position, the initial three-dimensional model is transformed in terms of angle and position to obtain a three-dimensional model of the target stimulus.

[0111] Furthermore, based on the initial electrical contact state information of each electrical stimulation matrix module and the initial angle state information (such as size information, rotatable angle, and initial angle) of each elastic frame, the three-dimensional coordinates of each electrical contact on each electrical stimulation matrix module are obtained respectively.

[0112] The initial three-dimensional model is obtained based on the three-dimensional coordinates of each electrical contact on each electrical stimulation matrix module;

[0113] Based on the offset of the electromagnetic spring valve corresponding to each electrical stimulation matrix module relative to the initial angle, the rotation angle of each elastic frame relative to the initial position, and the initial three-dimensional model, a three-dimensional model of the target stimulus is constructed.

[0114] In one possible implementation, a typical application process of the transcutaneous electrical stimulation device is as follows: First, the user wears the device with the top of the head and the back of the head as positioning points; the control module (which includes an acupoint positioning submodule, an automatic electrical stimulation planning submodule, multiple sets of coordinated electrical stimulation submodules, a wireless communication submodule, and a power supply submodule, with the acupoint positioning submodule performing this in this case) automatically analyzes the spring deformation information fed back by each electrical stimulation matrix module to obtain the electrical contact points on the electrical stimulation matrix module corresponding to each acupoint under the target acupoint selection rules; then, external communication transmits the user's target electrical stimulation prescription to the automatic electrical stimulation planning submodule in the control module through the wireless communication submodule; the automatic electrical stimulation planning submodule plans the discharge amount, discharge frequency, discharge waveform, duration, and coordination between different acupoints for each point and its adjacent electrical contacts according to the target electrical stimulation prescription; in addition, the multiple sets of coordinated electrical stimulation submodules in the control module perform electrical stimulation on the acupoints involved according to the output of the automatic electrical stimulation planning submodule.

[0115] For example, in the processing flow of the acupoint positioning submodule of the control module, after the user wears the device, the top of the head, philtrum, and chin are used as positioning points. The elastic frame is used to press the electrical stimulation matrix module onto the skin surface. At this time, the spring solenoid valves inside the electrical stimulation matrix module are in an energized spring state. The skin surface bounces the metal contacts of the electrical contacts to a stable position. At this time, based on the state of each spring solenoid valve of each electrical stimulation matrix module, as well as the pre-calibrated relative positional relationship between the rigid and elastic structures and the rotation amount of the elastic frame, the coordinates of each electrical stimulation matrix module in the three-dimensional virtual space can be obtained. In this way, multiple sets of three-dimensional coordinates of all electrical stimulation matrix modules are obtained. Using the coordinates of all points of all electrical stimulation matrix modules, a three-dimensional model can be fitted.

[0116] S802. According to the target acupoint selection rules, determine the coordinate positions of each acupoint corresponding to each electrical stimulation matrix module on the three-dimensional model of the target stimulus.

[0117] In one possible implementation, in the processing flow of the acupoint positioning submodule of the control module, the vertices of the three-dimensional model are used as the base points. According to the target acupoint selection rules, the position of each acupoint on the surface of the three-dimensional model is calculated, and each position is converted to correspond to a point in the dot matrix coordinate system of each electrostimulation dot matrix module. The coordinates of this point can be floating-point numbers. Similar calculations are performed on all acupoints to obtain the coordinate positions of all acupoints corresponding to each electrostimulation dot matrix module.

[0118] S803. Based on the target electrical stimulation prescription and the coordinate positions of each acupoint corresponding to each electrical stimulation matrix module, obtain the discharge mode parameters of the electrical stimulation matrix module at the positions surrounding each acupoint.

[0119] In one possible implementation, in the processing flow of the automatic electrostimulation planning submodule of the control module, all acupoints output by the acupoint positioning submodule correspond to the coordinate positions on each electrostimulation dot matrix module, as well as the user's target electrostimulation prescription; each electrostimulation controller calculates the output waveform of each electrical contact based on the acupoint coordinates and stimulation waveform, so as to achieve accurate fitting of the discharge waveform and stimulation position corresponding to the target electrostimulation prescription.

[0120] S804. The target electrical stimulation prescription is fitted with information based on the discharge mode parameters, and a three-dimensional discharge field matrix for each electrical stimulation matrix module is generated based on the fitting results and the discharge duration information within the target electrical stimulation prescription. The discharge mode parameters include at least one of the following: discharge waveform, current state, and switching frequency.

[0121] In one possible implementation, the discharge waveform of each electrical contact on each electrical stimulation matrix module is obtained based on the target electrical stimulation prescription and the coordinate positions of each acupoint corresponding to each electrical stimulation matrix module.

[0122] Based on the stimulation range and frequency of the target electrical stimulation prescription, obtain the current state and switching frequency of other electrical contacts around the discharge center of each electrical stimulation matrix module.

[0123] For example, in the processing flow of the automatic electrical stimulation planning submodule of the control module, the discharge / conduction state and switching frequency of other electrical contacts around the discharge center are planned according to the stimulation range and stimulation frequency of the target electrical stimulation prescription. Based on the discharge duration, stimulation range, switching frequency, stimulation frequency and stimulation waveform, a matrix of three-dimensional discharge field matrix is ​​formed for each electrical stimulation dot matrix module. The plane containing the X-axis and Y-axis is the dot matrix matrix, and the Z-axis is the time axis. The matrix of the above three-dimensional discharge field matrix is ​​input into the matrix digital filter in the electrical stimulation dot matrix module in time sequence by the electrical stimulation controller. All electrical stimulation controllers use the same time signal source to ensure the timing synchronization of stimulation at each location.

[0124] S805. Based on the three-dimensional discharge field matrix of each electrical stimulation matrix module, control each electrical stimulation matrix module to execute the stimulation operation specified in the target electrical stimulation prescription.

[0125] In one possible implementation, the epidermal current signal waveform of the acupoint corresponding to each electrical stimulation matrix module is obtained through the feedback electrical contacts on each electrical stimulation matrix module.

[0126] Based on the epidermal current signal waveform of the acupoints corresponding to each electrical stimulation matrix module, the actual discharge start time and electrical signal recovery time of each acupoint are obtained.

[0127] Based on the actual discharge start time corresponding to each acupoint and the discharge duration information in the target electrical stimulation prescription, the subsequent discharge time corresponding to each acupoint is corrected.

[0128] Based on the recovery time of the electrical signal corresponding to each acupoint and the discharge duration information in the target electrical stimulation prescription, the subsequent three-dimensional discharge field matrix of the electrical stimulation matrix module corresponding to each acupoint is corrected.

[0129] For example, based on the actual discharge start time corresponding to each acupoint and the discharge duration information in the prescription information, the deviation of the actual discharge start time corresponding to each acupoint relative to the timing plan is obtained;

[0130] Based on the deviation between the actual discharge start time of each acupoint and the timing plan, the subsequent discharge operations corresponding to each acupoint are executed in advance.

[0131] For example, based on the recovery time of the electrical signal corresponding to each acupoint and the discharge duration information in the prescription information, the deviation of the recovery time of the electrical signal corresponding to each acupoint relative to the timing plan is obtained;

[0132] Based on the deviation of the electrical signal recovery time corresponding to each acupoint from the timing plan, the subsequent three-dimensional discharge field matrix of the electrical stimulation matrix module corresponding to each acupoint is corrected to adjust the discharge duration corresponding to each acupoint.

[0133] For example, in the processing flow of the multiple sets of coordinated electrical stimulation submodules in this control module, based on the time-sequential coordinated discharge, a feedback electrical contact needs to be set within a certain range of each electrical stimulation matrix module to detect the current epidermal current signal. Throughout the electrical stimulation process, this feedback electrical contact monitors and transmits the epidermal current signal to the multiple sets of coordinated electrical stimulation submodules in real time. The multiple sets of coordinated electrical stimulation submodules will consider the discharge to end when the monitored signal waveform decreases to a certain threshold or shows a step decrease, rather than strictly following the time sequence. Subsequently, the multiple sets of coordinated electrical stimulation submodules will fine-tune the three-dimensional discharge field matrix of each electrical stimulation matrix module based on this judgment result. Simultaneously, the discharge judgment is also based on the rise to a certain threshold or a step increase being considered the start of discharge. Therefore, using the multiple sets of coordinated electrical stimulation submodules, the planned three-dimensional discharge field matrix will be adjusted in two directions to ensure that the discharge effect is consistent with the plan, rather than the discharge time.

[0134] In summary, firstly, a three-dimensional model of the target stimulus is obtained based on the electrical contact state information of each electrical stimulation matrix module and the angle state information of the elastic frame; then, according to the target acupoint selection rules, the coordinate positions of each acupoint corresponding to each electrical stimulation matrix module are determined on the three-dimensional model of the target stimulus; next, based on the target electrical stimulation prescription and the coordinate positions of the electrical stimulation matrix modules corresponding to each acupoint, a three-dimensional discharge field matrix of each electrical stimulation matrix module is generated; finally, based on the three-dimensional discharge field matrix of each electrical stimulation matrix module, each electrical stimulation matrix module is controlled to execute the stimulation operation specified in the target electrical stimulation prescription. The above scheme can realize the modernization, digitalization, and intelligence of multi-point precise automatic acupuncture, and improves the convenience and standardization of operation compared with traditional acupuncture methods.

[0135] The following simple example illustrates the content disclosed in the above embodiments:

[0136] 1) Taking the user's head as the target stimulus as an example, initially, the size, rotation angle and initial angle of each elastic frame are measured and determined to form an initial three-dimensional head model. The three-dimensional head model has the three-dimensional positions of the electrical contacts of all electrical stimulation matrix modules, and the coordinate system is a virtual spatial coordinate system.

[0137] 2) The control module and each electrical stimulation controller have power supply and signal control communication. The electrical stimulation controller generates a new modulation signal according to the signal, and can output the supplied current and modulation signal to the matrix digital filter in each electrical stimulation dot matrix module, and then transmit it to the metal contact.

[0138] 3) The electrical stimulation controller can cover the top and back of the head, the area connecting the top of the head and the temples, the area above and below the ears, the philtrum area, and the area below the chin. It also has 12 electrical stimulation controllers on the body, which are fixed to the body surface with a ring strap.

[0139] 4) After the user wears the device and it is fixed by the top of the head and chin, the position change of each electrical stimulation matrix module relative to the flexible buffer backplate is obtained according to the rotation angle of each elastic frame axis relative to the initial position. Then, the position of the metal contact on each electrical stimulation matrix module is obtained according to the offset of the electromagnetic spring valve of each metal contact. After the angle and position change of each point from the initial position, the target three-dimensional model is obtained.

[0140] 5) External communication inputs the target electrical stimulation prescription into the control module, determining the head acupoints including: Baihui-Taiyang (divided into three segments, four points in total), bilateral Fengchi points (needle tip pointing towards the contralateral lower orbit), Sishenchong points, Renzhong points, Shuaigu points and one inch to the left and right, Lianquan points and one inch to the left and right, and Houding points in the occipital region; body acupoints include: upper limbs: Jianyu, Quchi, Shousanli, Waiguan, Tongli, Hegu; lower limbs: Biguan, Yanglingquan, Zusanli, Sanyinjiao, Jiexi, Kunlun. The target electrical stimulation prescription also includes the stimulation angle, depth, frequency, axial rotation, and duration for each acupoint.

[0141] 6) The acupoint positioning submodule in the control module locates the position of each acupoint on the established target 3D model according to the description and definition of acupoints in the above steps, and converts it to the matrix coordinates of each electrical stimulation matrix module. Some electrical stimulation matrix modules may have multiple corresponding coordinates.

[0142] 7) The electrical stimulation planning submodule in the control module calculates the discharge mode parameters such as discharge waveform, frequency, and intensity of the electrical stimulation matrix module around each acupoint according to the above target electrical stimulation prescription, so as to fit the required angle, depth, frequency, axial rotation, etc., and generate the three-dimensional discharge field matrix of each electrical stimulation matrix according to the required duration.

[0143] 8) The data output of the electrical stimulation planning submodule is sent to multiple sets of coordinated electrical stimulation submodules in the control module. These multiple sets of coordinated electrical stimulation submodules control each electrical stimulation controller to start discharging, and use feedback electrical contacts to monitor the discharge status of each acupoint. The duration of all subsequent discharges is adjusted according to the actual discharge start time monitored. After each discharge, the subsequent time field is adjusted again according to the recovery time of the monitored electrical signal. For example, the discharge time of the subsequent discharge field is advanced according to the deviation of the initial discharge time of the previous discharge from the timing plan. The duration of the discharge can also be adjusted according to the deviation of the recovery time of the electrical signal of each point from the timing plan.

[0144] 9) Using the same application method, electrical stimulation controllers fixed to various parts of the user's body can achieve head-body coordination;

[0145] The above method is used to stimulate various acupoints of the user to complete the stimulation program specified in the target electrical stimulation prescription.
