Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a tDCS transcranial direct current stimulation system. Background Art

[0002] Neuropathic pain is considered a persistent chronic pain state, and pain may persist even after the original injury that caused the pain has been eliminated. According to the definition of the International Society for Pain, this pain is directly caused by damage or lesions in the somatic sensory nervous system, and its clinical symptoms are diverse, including untriggered pain (such as burning, tingling, throbbing pain, electric shock, etc.), excessive sensitivity to pain, and extreme sensitivity to pain. Such chronic pain not only seriously affects the health and quality of life of patients, but also increases the economic burden on families and society due to treatment costs. Studies have shown that the pathophysiological mechanism of neuropathic pain mainly involves peripheral sensitization, central sensitization, and glial cell activation. Among them, central sensitization mainly occurs in the superficial layer (layers I and II) of the dorsal horn of the spinal cord, and the upregulation of N-methyl-D-aspartate receptors (NMDA-R) of sensory neurons and the decrease in the expression of γ-aminobutyric acid receptors (GABA-R) of intermediate inhibitory neurons play a key regulatory role in the initiation and development of pain. Currently, the main methods for treating this pain include drug therapy, physical therapy, neuromodulation therapy, minimally invasive therapy and psychotherapy, among which drug therapy is the most common choice. However, only about 40% of patients can get satisfactory results through drug therapy, and even if some drugs can effectively relieve pain, their side effects may cause treatment to be forced to be interrupted. Therefore, it is of great value to find an economical, effective and widely applicable treatment method.

[0003] Transcranial direct current stimulation (tDCS) is a non-invasive transcranial brain stimulation method that has attracted attention for its significant analgesic effect, lasting effect, low side effects and economical advantages. Better analgesic effect and sustained effect can be achieved through repeated stimulation. In clinical practice, an anodic current of 1.0~2.0mA is often used to activate the primary motor cortex (M1) of the brain, and the treatment is continuous for 5~10 days, 20 minutes a day. Studies have shown that tDCS produces analgesic effects by adjusting the activity of neuronal networks and affects cortical excitability during and after the stimulation, which may be related to changes in the resting membrane potential of neurons, the regulation of synaptic plasticity and increased intracortical inhibition. In addition, tDCS can also affect distal brain areas associated with the stimulated area.

[0004] Li Bingbing et al. (Li Bingbing, Xu Tao, Wang Shengjie, et al. Observation on the effect of repetitive transcranial direct current stimulation in the treatment of neuropathic pain and preliminary exploration of its mechanism [J]. Chinese Journal of Physical Medicine and Rehabilitation, 2022, 44(4): 312-317) used the classic sciatic nerve chronic constriction injury (CCI) model to induce post-traumatic painful peripheral neuropathy in rats. The rats were given tDCS stimulation for 8 consecutive days to observe its analgesic effect, and the expression of NMDA-R and GABA-R in the dorsal horn of the spinal cord was studied to preliminarily explore the theoretical basis for the analgesic effect of tDCS. The study found that repetitive transcranial direct current stimulation can improve neuropathic pain response, and the improvement of hyperalgesia (thermal pain) is better than that of allodynia (mechanical pain). Its mechanism of action may be to downregulate spinal NR2B-NMDA-R to normal levels and partially upregulate GABAa-R.

[0005] The patent document with application publication number CN108671390A discloses an electrical stimulation device with high-precision positioning output function, including: a power supply unit, a tDCS transcranial direct current stimulator, a 5-channel current distributor and a cable, wherein the tDCS transcranial direct current stimulator and the 5-channel current distributor are connected via a cable, and the power supply unit is connected to the tDCS transcranial direct current stimulator and the 5-channel current distributor to supply power to the tDCS transcranial direct current stimulator and the 5-channel current distributor, wherein the 5-channel current distributor has 5 electrodes, and these electrodes can be configured in one of the following two combinations: (1) 1 cathode and 4 anodes; (2) 1 anode and 4 cathodes. This electrical stimulation device cannot provide patients with professional treatment plans, nor can it automatically update treatment plans.

[0006] Current professional transcranial direct current stimulation devices have the disadvantages of being bulky, complex in structure, and requiring patients to go to hospitals or other professional institutions for treatment, which brings inconvenience to patients in frequent commuting between hospitals and homes. In addition, professional transcranial direct current stimulation devices are also relatively expensive, making it difficult for patients to purchase the devices themselves to perform effective transcranial direct current stimulation treatments at home. If patients purchase portable transcranial direct current stimulation devices for treatment directly at home, there are the following defects: (1) inaccurate stimulation location; (2) inaccurate intensity and time of electrical stimulation; (3) insufficient electrical stimulation accuracy. This will significantly reduce the therapeutic effect of portable transcranial direct current stimulation devices. Therefore, how to enable patients to receive treatment at home through portable transcranial direct current stimulation devices and improve their treatment accuracy is a technical problem that has not yet been solved.

[0007] To solve this problem, the present invention improves the structure of the tDCS transcranial direct current stimulation system so that patients can easily carry it and receive professional treatment at home. In this way, patients can independently perform high-quality transcranial direct current stimulation treatment at home, thereby improving the convenience and effect of treatment.

[0008] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0009] Current professional transcranial direct current stimulation devices have the disadvantages of being bulky, complex in structure, and requiring patients to go to hospitals or other professional institutions for treatment, which brings inconvenience to patients in frequent commuting between hospitals and homes. In addition, professional transcranial direct current stimulation devices are also relatively expensive, making it difficult for patients to purchase the devices themselves to perform effective transcranial direct current stimulation treatments at home. If patients purchase portable transcranial direct current stimulation devices for treatment at home, there are the following defects: (1) inaccurate stimulation location; (2) inaccurate intensity and time of electrical stimulation; (3) insufficient electrical stimulation accuracy. This will significantly reduce the therapeutic effect of portable transcranial direct current stimulation devices. Therefore, how to enable patients to receive treatment at home through portable transcranial direct current stimulation devices and improve their treatment accuracy is a technical problem that has not yet been solved.

[0010] The prior art has already seen technical solutions that adjust the treatment parameters of transcranial electrical stimulation equipment and evaluate the efficacy by combining actual human body parameters. For example, the patent document with publication number CN116510173A discloses a neural regulation system, including an acquisition module for collecting human body sign parameters and transmitting the collected human body sign parameters to a data analysis module, a data analysis module for analyzing the received human body sign parameters and finding the best treatment parameters, the data analysis module transmitting the treatment parameters to the transcranial electrical stimulation module, and the transcranial electrical stimulation module analyzing the received treatment parameters and outputting a current waveform based on the analyzed treatment parameters. This technical solution collects and analyzes human body sign parameters through an acquisition module and a data analysis module, and combines different brain electrical stimulations such as tDCS to form a closed-loop system, thereby realizing personalized dynamic real-time regulation and treatment of different nervous system diseases. However, the adjustment process of the treatment parameters in this technical solution is carried out for the same transcranial electrical stimulation module. Since the digital-to-analog conversion parameters and the setting position of the stimulation electrode structure of the same transcranial electrical stimulation module are relatively fixed, there will be no hardware differences. Therefore, it is only necessary to make adaptive adjustments based on the actual patient's physical sign parameters collected, and the therapeutic effect produced is also relatively certain. On the contrary, the present invention is aimed at the problem of the associated adjustment of treatment parameters of at least two different transcranial direct current stimulation devices in different time and space. On the one hand, there are structural differences between the professional transcranial direct current stimulation devices operated by medical staff in medical institutions and the portable transcranial direct current stimulation devices used independently by patients at home, which leads to the corresponding treatment parameter adjustment methods being inconsistent. Even if the patient knows the treatment parameters of the medical staff on the professional transcranial direct current stimulation device, it is impossible to directly apply it to the treatment parameter adjustment process of the portable transcranial direct current stimulation device. On the other hand, the transcranial direct current stimulation treatment process requires updating the treatment plan at different stages according to the specific therapeutic effect. When the patient is at home, medical staff cannot directly verify the treatment effect of the portable transcranial direct current stimulation device. They can only update the treatment plan for the next stage through the patient's voluntary visit to a medical institution and the parameter adjustment and verification process of the professional transcranial direct current stimulation device. Therefore, it is impossible to realize the remote update process of the treatment plan of the portable transcranial direct current stimulation device at different treatment stages.

[0011] In view of the deficiencies of the prior art, the present invention provides a tDCS transcranial direct current stimulation system, including a portable tDCS treatment helmet, a mobile terminal and a server. The portable tDCS treatment helmet determines the initial treatment parameters based on the best treatment plan determined by the doctor; the first stage of home treatment is performed based on the initial treatment parameters; the mobile terminal feeds back the scale data filled in by the patient to the server; the server is connected to a professional transcranial direct current stimulation device; during the process of the professional transcranial direct current stimulation device treating the patient, the best treatment plan determined by the doctor is recorded; wherein, the server analyzes and determines the treatment plan for the next stage according to the received scale data; and updates the treatment parameters of the portable tDCS treatment helmet according to the treatment plan for the next stage.

[0012] Different from the prior art, the tDCS transcranial direct current stimulation system of the present invention has two different transcranial direct current stimulation devices, including a professional transcranial direct current stimulation device used by doctors in professional institutions and a portable tDCS treatment helmet used by patients at home. The portable tDCS treatment helmet can determine the initial treatment parameters during the doctor's implementation of the optimal treatment plan, and can update the next stage of the treatment plan based on the analysis of the home treatment effect of the initial treatment parameters. Based on the above-mentioned distinguishing technical features, the problems to be solved by the present invention may include: how to adjust the treatment parameters of a portable tDCS treatment helmet with different structures according to the treatment parameters of a professional transcranial direct current stimulation device, so that patients can achieve the same treatment effect in different time and space, and how to realize the remote update process of treatment parameters at different treatment stages according to the treatment effect of the portable tDCS treatment helmet. Specifically, the present invention can adjust the treatment parameters of the portable tDCS treatment helmet according to the optimal treatment plan formed by the doctor through the professional transcranial direct current stimulation device to treat the patient, so that it has the same immediate treatment feedback effect, and the patient can perform home treatment according to the treatment parameters of the portable tDCS treatment helmet determined at this time, without having to go to a professional institution for transcranial direct current stimulation. The home treatment parameters determined in this way can achieve the same treatment effect as that of a professional institution. The tDCS transcranial direct current stimulation system of the present invention helps patients achieve professional treatment at home. Through remote connection, the present invention can also obtain accurate data on the patient's home treatment and actively supervise or remind the patient to implement the treatment plan. For the situation where the patient is not actively treated according to the treatment plan, the hospital terminal of the present invention can actively understand the patient's implementation status and actively remind, thereby enabling the patient to obtain better treatment effects.

[0013] According to a preferred embodiment, the portable tDCS treatment helmet includes at least one cathode, at least one anode and a control unit. The control unit is remotely connected to the server through a mobile terminal. During the process of the professional transcranial direct current stimulation device treating the patient according to the optimal treatment plan, the server records the patient's first stress physiological parameters and electrical stimulation parameters through the physiological parameter sensor. During the process of constructing the initial treatment parameters using the portable tDCS treatment helmet, the server monitors the patient's second stress physiological parameters through the physiological parameter sensor. When the second stress physiological parameters are close to or equal to the first stress physiological parameters, the electrical stimulation parameters of the portable tDCS treatment helmet are determined as the initial treatment parameters.

[0014] Different from the prior art, the portable tDCS treatment helmet of the present invention can use the first stress physiological parameter and the corresponding electrical stimulation parameter generated by the patient during the execution of the optimal treatment plan by the professional transcranial direct current stimulation device as a reference for constructing the initial treatment parameters, and adjust the electrical stimulation parameters of the portable tDCS treatment helmet so that the second stress physiological parameter generated by the patient approaches or is equal to the first stress physiological parameter, and then determine the electrical stimulation parameter at this time as the initial treatment parameter. Based on the above-mentioned distinguishing technical features, the problems to be solved by the present invention may include: how to determine the initial treatment parameters of the portable tDCS treatment helmet and improve the accuracy of the treatment parameter setting. Specifically, when receiving electrical stimulation, a person will generate stress physiological parameters. In a short period of time, a person's stress physiological parameters are approximate or consistent. Therefore, providing an effective reference for setting the initial treatment parameters based on the stress physiological parameters can reduce the setting error of the initial treatment parameters.

[0015] According to a preferred embodiment, during the process of treating a patient with a professional transcranial direct current stimulation device according to the optimal treatment plan, the server is connected to the image acquisition device to collect the patient's three-dimensional head data and determine the first coordinate parameters of the electrode stimulation position. The server calculates the second coordinate parameters of the electrode for implementing electrical stimulation based on the electrode distribution characteristics of the portable tDCS treatment helmet fed back by the mobile terminal and the patient's three-dimensional head data, thereby achieving the effect of electrical stimulation at the head position corresponding to the first coordinate parameters.

[0016] Since the portable tDCS treatment helmet has different adaptability to the patient's head, whether the electrode can stimulate the treatment area is the core issue of the treatment. The portable tDCS treatment helmet has structural differences from professional transcranial direct current stimulation equipment. Therefore, the present invention obtains the second coordinate parameter of the portable tDCS treatment helmet for effective operation by calculating the coordinate parameter of the stimulation, so as to improve the effectiveness of the stimulation of the treatment area.

[0017] According to a preferred embodiment, the server periodically requests the mobile terminal for request information of the scale data, and the mobile terminal generates reminder information of the scale data based on the request information, so that the patient inputs the scale data through the mobile terminal.

[0018] Since patients may forget to input the scale data due to their busy daily life at home, most patients need to be reminded passively before they will actively input the scale data. The present invention obtains the scale data through reminder information, ensuring that the scale data can be obtained in time.

[0019] According to a preferred embodiment, when the mobile terminal is connected to at least one physiological parameter sensor, the mobile terminal sends the second stress physiological parameter and the treatment parameter during home treatment to the server in an associated manner.

[0020] Associating stress physiological parameters with treatment parameters helps the server analyze whether the portable tDCS treatment helmet has provided electrical stimulation to the patient in accordance with the treatment parameters, thereby reducing the situation where treatment information is analyzed incorrectly and also reducing the situation where the ineffective work of the portable tDCS treatment helmet is analyzed as effective work.

[0021] According to a preferred embodiment, when at home, the server analyzes the validity of the scale data based on the second stress physiological parameter fed back by the mobile terminal. When the validity of the scale data is lower than a preset threshold, the server sends request information for the scale data and reminder information related to the validity to the mobile terminal again.

[0022] When patients enter scale data, they often enter inaccurate data due to their non-professional background or lack of medical knowledge. Some patients even enter false scale data. This requires the server to be able to evaluate the validity of the scale data in a timely manner, thereby prompting or guiding patients to provide more accurate scale data.

[0023] According to a preferred embodiment, when the validity of the scale data is not less than a preset threshold, the server analyzes the treatment effect of the current best treatment plan based on the scale data and determines the treatment plan for the next stage. When the scale data is judged to be valid, the result obtained by the server based on the scale data analysis is accurate.

[0024] According to a preferred embodiment, the mobile terminal sends the treatment parameters of the portable tDCS treatment helmet to the server according to a preset cycle, so that the server can judge whether the patient has implemented the best treatment plan, thereby reducing the probability of erroneous analysis of the treatment effect of the best treatment plan. Some patients may not actively follow the treatment plan, such as refusing to accept electrode stimulation or not wearing the portable tDCS treatment helmet at the prescribed time. Such behavior will undoubtedly reduce the effectiveness of the treatment plan. Therefore, the server should master the treatment parameters of the portable tDCS treatment helmet, such as treatment time, electrical stimulation frequency and other information, to confirm whether the portable tDCS treatment helmet is running according to the treatment plan.

[0025] According to a preferred embodiment, when the treatment parameters of the portable tDCS treatment helmet need to be corrected, the server sends a correction reminder message to the mobile terminal so that the patient can bring the portable tDCS treatment helmet to the hospital to redetermine the treatment parameters. After long-term use or bumps and collisions, the electrodes of the portable tDCS treatment helmet may be misplaced, resulting in inaccurate treatment areas, thereby weakening the treatment effect. Therefore, the server needs to detect abnormal operation in a timely manner and issue correction reminder messages in a timely manner.

[0026] According to a preferred embodiment, when the treatment parameters of the portable tDCS treatment helmet statistically deviate from the treatment parameters determined last time, the server determines that the portable tDCS treatment helmet needs to be calibrated or repaired. The server needs to analyze the data deviation to promptly detect abnormal operation and issue correction reminder information in a timely manner. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following is a detailed description with reference to the accompanying drawings.

[0035] The operating principle of the present invention includes:

[0036] First, the patient is treated with a professional transcranial direct current stimulation device in the hospital, and the best treatment plan is determined by a medical expert. The initial treatment parameters of the portable tDCS treatment helmet 100 are determined according to the best treatment plan. Then, the patient uses the portable tDCS treatment helmet 100 for the first stage of treatment in a home environment. During the treatment process, the mobile terminal 200 will feedback the scale data 210 filled in by the patient to the server 300. The server 300 will analyze the received scale data 210 and determine the treatment plan for the next stage. Finally, the server 300 will update the treatment parameters of the portable tDCS treatment helmet 100 according to the treatment plan for the next stage.

[0037] Transcranial direct current stimulation (tDCS) is a neuromodulation technique that changes the excitability of the cerebral cortex by applying a weak direct current through electrodes placed on the scalp. This stimulation can increase or decrease activity in specific brain areas, potentially improving cognitive function, relieving pain, improving motor skills, or treating certain neuropsychiatric disorders.

[0038] Portable tDCS treatment helmet 100: Similar to the helmet used for transcranial direct current stimulation treatment, it can be worn by the patient and is easy to carry.

[0039] Current professional transcranial direct current stimulation devices have the disadvantages of being bulky, complex in structure, and requiring patients to go to hospitals or other professional institutions for treatment, which brings inconvenience to patients in frequent commuting between hospitals and homes. In addition, professional transcranial direct current stimulation devices are also relatively expensive, making it difficult for patients to purchase the devices themselves to perform effective transcranial direct current stimulation treatments at home. If patients purchase portable transcranial direct current stimulation devices for treatment at home, there are the following defects: (1) inaccurate stimulation location; (2) inaccurate intensity and time of electrical stimulation; (3) insufficient electrical stimulation accuracy. This will significantly reduce the therapeutic effect of portable transcranial direct current stimulation devices. Therefore, how to enable patients to receive treatment at home through portable transcranial direct current stimulation devices and improve their treatment accuracy is a technical problem that has not yet been solved.

[0040] In view of the shortcomings of the prior art, the present invention provides a tDCS transcranial direct current stimulation system, such as Figure 3 and Figure 4 As shown, it includes a portable tDCS treatment helmet 100, a mobile terminal 200 and a server 300. The portable tDCS treatment helmet 100 is connected to the mobile terminal 200 in a wired or wireless manner. The mobile terminal 200 is held by the patient, and the built-in application module can count the treatment parameters of the portable tDCS treatment helmet 100 and communicate remotely with the server 300. The mobile terminal 200 is, for example, a smart device held by the patient, such as a smart phone, a laptop, a tablet computer, smart glasses, a smart watch, a smart bracelet, etc., which can be installed with an application module. The server 300 is set in a hospital. In addition, the server 300 can be connected to the hospital's HIS system, allowing doctors to access the patient's treatment data directly through the HIS system. The mobile terminal 200 and the server 300 communicate remotely so that the server 300 can receive the scale data 210 and the operating parameters of the portable tDCS treatment helmet 100 in a timely manner and analyze the treatment plan for the next stage.

[0041] Specifically, the server 300 is connected to a professional transcranial direct current stimulation device. The main components of the professional transcranial direct current stimulation device include: (1) Main control unit: used to set parameters such as the intensity, duration and stimulation mode of the current. (2) Electrode: a conductive device placed directly on the scalp for transmitting direct current to the brain. The electrode usually includes an anode 120 (positive electrode) and a cathode 110 (negative electrode). The electrode is connected to the main control unit through a line. (3) Interface system: allows medical staff to input treatment parameters and can display data such as current and voltage during the treatment process in real time. (4) Safety system: includes an automatic shutdown system, overload protection, and skin resistance detection to ensure the safety of the treatment process.

[0042] Professional transcranial direct current stimulation devices take up a large space, are not easy to carry, and require trained medical staff to operate and monitor through an interface system. For patients, professional transcranial direct current stimulation devices are difficult to operate. The electrodes of professional transcranial direct current stimulation devices accurately locate the brain area, and the electrode parameters implemented are relatively accurate. Therefore, professional transcranial direct current stimulation devices are set up in professional institutions such as hospitals and cannot be used by patients at home.

[0043] During the process of the professional transcranial direct current stimulation (tDCS) device treating the patient, the server 300 records the best treatment plan determined by the doctor. Preferably, the server 300 records the best treatment plan determined by the doctor in real time.

[0044] Specifically, the doctor will set various treatment parameters through professional tDCS equipment according to the patient's specific situation. These parameters include the intensity of the stimulation current, the frequency of stimulation, the location of the stimulation area, and the total duration of treatment. The doctor will make fine adjustments based on the patient's response and symptoms to form the best treatment plan.

[0045] When the treatment begins, the professional tDCS device will release precise direct current stimulation to the patient's brain through electrodes according to the preset parameters. During the treatment process, the professional tDCS device will monitor and record various data in real time, such as the actual intensity of the stimulation current, the duration of the stimulation, and the position of the electrodes.

[0046] The server 300 performs real-time data exchange with the tDCS device. During the process of the professional tDCS device treating the patient, all treatment information, including preset treatment parameters, actual treatment data, and the best treatment plan determined by the doctor, will be instantly received and saved by the server 300.

[0047] Furthermore, the server 300 can also provide doctors with treatment feedback information through data analysis, which can not only help doctors evaluate the effect of the current treatment plan, but also provide reference for subsequent treatment.

[0048] like Figure 4 As shown, the portable tDCS therapy helmet 100 determines initial therapy parameters based on the optimal therapy plan determined by a physician.

[0049] like Figure 1 and Figure 2 As shown, the portable tDCS treatment helmet 100 includes at least one cathode 110, at least one anode 120 and a control unit 130. Specifically, the portable tDCS treatment helmet 100 includes a shell 140. The shell 140 is designed as a structure for the patient to wear on the head and is equipped with various components. The material of the shell 140 is not limited and can be selected according to the needs, and can be plastic or metal.

[0050] The cathode 110 and the anode 120 are distributed in a checkerboard pattern on the inner surface of the housing 140. The cathode 110 and the anode 120 are staggered. The staggered arrangement ensures that the current can evenly and effectively cover the target brain area. Taking into account the differences in the shape of the patient's head, the electrodes are distributed in a checkerboard pattern to ensure that accurate cathode 110 or anode 120 electrical stimulation can be provided according to the positioning requirements of different brain areas.

[0051] The control unit 130 is arranged in the groove 150 at the end of the housing 140, which not only protects the core components of the device, but also ensures the overall compactness. The control unit 130 is electrically connected to the cathode 110 and the anode 120 through a precise circuit, transmits control signals in real time, and accurately regulates key treatment parameters such as the intensity, duration and mode of the current to achieve personalized treatment effects. The control unit 130 is also connected to at least one communication port 160. The communication port 160 is used for the control unit 130 to connect to the mobile terminal 200 in a wired or wireless manner. The communication port 160 is, for example, a Bluetooth communication port, a WiFi communication port, and a USB communication port. Through the connection between the control unit 130 and the mobile terminal 200 and the remote connection between the mobile terminal 200 and the server 300, the doctor or user can remotely adjust the treatment parameters, monitor the treatment progress, and even receive real-time feedback data, thereby achieving more intelligent and personalized treatment management. The control unit 130 can also be connected to the indicator light 170. The indicator light 170 is arranged on the surface of the housing 140 to intuitively display the working status of the device. When the indicator light 170 is on, the user can know that the helmet is running; when the indicator light 170 is off, it means that the device is in the off state. Preferably, the position of each electrode can be adjusted mechanically to adapt to heads with individual differences. After each electrode is manually fine-tuned, the electrode is mechanically fixed. In this way, when the patient takes the portable tDCS treatment helmet 100 home for home treatment, electrode displacement can be avoided, and the problem of inaccurate target area of ​​electrode stimulation can also be avoided. Preferably, the connecting end of each electrode is provided with a micro-elastic component. For example, a micro-spring, so that the electrode can contact the target area and stably adhere to the target area, avoiding discontinuous contact between the electrode and the skin of the head, thereby ensuring the effect of electrical stimulation.

[0052] Since the electrodes of professional tDCS equipment are flexibly arranged, the electrodes on the portable tDCS treatment helmet 100 cannot be moved at will, and the electrode positions and corresponding treatment parameters of the portable tDCS treatment helmet 100 need to be adjusted according to the best treatment plan. The treatment parameters include the number and position of the electrodes, the intensity of the stimulation current, the frequency of stimulation, the duration of each stimulation, the total duration, and other data.

[0053] Specifically, the server 300 needs to calculate personalized treatment parameters suitable for the portable tDCS treatment helmet 100 based on the best treatment plan determined by the doctor.

[0054] Since the electrode layout of the portable tDCS treatment helmet 100 may be different from that of professional equipment, it is necessary to establish a parameter mapping table to map the treatment parameters of the professional tDCS equipment to the electrode layout of the portable tDCS helmet 100. During the mapping process, taking into account the individual differences in the patient's head, the checkerboard-shaped electrodes can be adjusted according to the patient's brain positioning area to ensure that the electrical stimulation can accurately act on the target brain area. The mapping table takes into account the checkerboard electrode layout of the portable tDCS treatment helmet 100 and the specific positioning area of ​​the patient's brain, ensuring that the electrical stimulation can accurately cover the target brain area. Table 1 shows a parameter mapping table for illustration.

[0055] Table 1: Parameter mapping table of the portable tDCS therapy helmet 100

[0056]

[0057] In Table 1, each row represents the treatment parameters of an electrode pair. The electrode positions of professional tDCS devices (such as F3, F4, etc.) correspond to the standard positions in the international 10-20 system, while the electrode positions of the portable tDCS treatment helmet 100 (such as E1, E2, etc.) are redefined based on the chessboard electrode layout of the helmet. Current intensity (mA) is the current intensity applied to each electrode. During the mapping process, it is necessary to ensure that the portable tDCS treatment helmet 100 can provide the same current intensity as the professional tDCS device. Stimulation duration (minutes) is the length of time each electrode pair stimulates. During the mapping process, it is necessary to ensure that the portable tDCS treatment helmet 100 can stimulate for the specified duration. The electrode positions of the portable tDCS treatment helmet 100, i.e., numbers E1, E2, etc., correspond to the standard electrode positions in professional devices, such as F3, F4, etc. During the mapping process, the electrode positions need to be adjusted according to the patient's brain localization area to ensure that the electrical stimulation can accurately act on the target brain area.

[0058] Preferably, in actual applications, medical staff will adjust the parameters in the parameter mapping table according to the patient's specific conditions (such as EEG and brain imaging results). For example, if a patient's specific brain area requires stronger stimulation, the medical staff may increase the current intensity of the corresponding electrode. Similarly, if a certain brain area is particularly sensitive to stimulation, the medical staff may reduce the stimulation duration or current intensity.

[0059] The portable tDCS treatment helmet 100 performs the first stage of home treatment based on the initial treatment parameters. In the home state, the mobile terminal 200 feeds back the scale data 210 filled in by the patient to the server 300. The server 300 analyzes and determines the treatment plan for the next stage based on the received scale data 210. Preferably, the mobile terminal 200 feeds back the operating data of the portable tDCS treatment helmet 100 to the server 300. The operating data includes the working data and treatment data of the portable tDCS treatment helmet 100. The working data is, for example, data related to operation and unrelated to treatment, such as the start-up time and the shutdown time.

[0060] Table 2 shows a neuropathic pain treatment effect scale and the scale content. Table 3 shows the scale table and scale data 210. After the patient uses the portable tDCS treatment helmet 100 every day, he needs to fill in this scale on the mobile terminal 200. The scale data 210 is automatically sent to the server 300. The server 300 analyzes the patient's response based on these scale data 210 and adjusts the initial treatment parameters accordingly.

[0063] Table 3: Scale data sample

[0064]

[0065] The server 300 collects and analyzes these scale data 210. According to the data of item 1 (pain intensity), it can be seen that the patient's pain intensity has decreased from 8 points in the early stage to 4 points. Based on this trend, the server 300 may recommend continuing the current treatment parameters or appropriately reducing the stimulation intensity as needed. If the scores of item 3 (the impact of pain on daily activities) and item 4 (the impact of pain on sleep) continue to improve, it means that the treatment effect is positive. Otherwise, it may be necessary to adjust the treatment strategy or explore other intervention measures.

[0066] The server 300 updates the treatment parameters of the portable tDCS treatment helmet 100 according to the treatment plan for the next stage.

[0067] Specifically, the server 300 receives the patient's scale data 210 from the mobile terminal 200 in real time and stores it in a secure database. The server 300 is equipped with an artificial intelligence algorithm model, which can analyze key indicators such as the patient's pain intensity, frequency, impact on daily activities and sleep, and mood changes. Through trend analysis, the server 300 can identify positive or negative changes in the treatment effect. The server 300 sends the data analysis results to the doctor's hospital terminal and sends a reminder message 220 at the same time, so that the doctor can promptly determine the next stage of treatment plan, the expected pain relief level, and the corresponding treatment parameters.

[0068] After the doctor inputs the next stage of the treatment plan through the hospital terminal, the server 300 forms and updates new treatment parameters that match the portable tDCS treatment helmet 100 based on the new treatment plan and parameter mapping table. The server 300 sends new treatment parameters to the portable tDCS treatment helmet 100 via a secure wireless connection. These parameters may include current intensity, stimulation frequency, treatment duration, and electrode placement. After updating the treatment parameters, the server 300 will notify the patient of any changes in the treatment plan through the mobile terminal 200, and provide necessary guidance and suggestions. After the treatment parameters are updated, the server 300 will continue to receive and monitor the patient's scale data 210 to ensure that the treatment effect meets expectations. If necessary, the server 300 will adjust the treatment parameters again.

[0069] For example, after the first phase of treatment, the patient's pain intensity was reduced from 8 points to 4 points, but the pain still had a high impact on daily activities (7 points). The analysis results of server 300 showed that although the pain was relieved, the patient's quality of life did not improve significantly. Therefore, the doctor decided to adjust the treatment plan, with the goal of reducing the impact of pain on daily activities to less than 3 points in the next phase.

[0070] The server 300 calculates new treatment parameters according to the treatment plan for the next stage, including increasing the stimulation frequency and optimizing the electrode placement to more accurately target the pain area. These treatment parameters are instantly updated to the portable tDCS treatment helmet 100 via a wireless connection. At the same time, the patient receives a notification through the mobile terminal 200 to know the changes in the treatment parameters and how to correctly use the updated portable tDCS treatment helmet 100.

[0071] As described above, through remote connection, the present invention can obtain accurate data of the patient's home treatment and actively supervise or remind the patient to implement the treatment plan. If the patient is not actively following the treatment plan, the hospital terminal of the present invention can actively understand the patient's implementation status and actively remind, thereby enabling the patient to obtain better treatment results.

[0072] like Figure 5As shown, the system of the present invention may further include a physiological parameter sensor 310. The physiological parameter sensor 310 can be connected to the server 300 in a wired or wireless manner to send the collected first stress physiological parameter to the server 300. The physiological parameter sensor 310 can also be connected to the mobile terminal 200 in a wired or wireless manner to send the collected second stress physiological parameter to the mobile terminal 200. The physiological parameter sensor 310 may be integrated in the mobile terminal 200 or may not be integrated in the mobile terminal 200. When the physiological parameter sensor 310 is a smart watch or a smart bracelet, and the mobile terminal 200 is a smart phone or a computer, the physiological parameter sensor 310 is not integrated in the mobile terminal 200. The physiological parameter sensor 310 can collect physiological parameters such as the patient's heart rate, body temperature, and blood oxygen.

[0073] like Figure 5 As shown, in a hospital treatment environment, the server 300 is connected to the physiological parameter sensor 310 for communication. The communication connection between the server 300 and the physiological parameter sensor 310 constitutes a critical data exchange network, which is essential for ensuring that the professional tDCS device can be accurately adjusted according to the patient's real-time stress physiological response. In the present invention, the physiological parameters collected in the case of treatment with a professional tDCS device are referred to as first stress physiological parameters, and the physiological parameters collected in the case of treatment with a portable tDCS treatment helmet 100 are referred to as second stress physiological parameters.

[0074] When the professional tDCS device treats the patient according to the optimal treatment plan, the physiological parameter sensor 310 continuously monitors the patient's first stress physiological parameters, such as heart rate, blood pressure, skin conductivity and body temperature. At the same time, the professional tDCS device also records electrical stimulation parameters, including current intensity, frequency and duration. The physiological parameter sensor 310 transmits the first stress physiological parameters to the server 300 in real time through an encrypted channel. The server 300 stores the first stress physiological parameters in a database connected to it for subsequent analysis and call. Based on the stored first stress physiological parameters, the server 300 can dynamically adjust the treatment parameters and send them to the doctor terminal, which is confirmed by the doctor through the doctor terminal to ensure that the treatment plan always matches the patient's physiological state. This personalized adjustment helps to improve the treatment effect and reduce the side effects of electrical stimulation.

[0075] The artificial intelligence algorithm model inside the server 300 performs real-time analysis on the transmitted first stress physiological parameters to understand the patient's physiological response and evaluate the treatment effect, and adjust the treatment plan in a timely manner. The server 300 associates and stores the electrical stimulation parameters of the determined optimal treatment plan with the corresponding first stress physiological parameters.

[0076] When the portable tDCS treatment helmet 100 is used to construct the initial treatment parameters, the server 300 uses the first stress physiological parameters monitored by the physiological parameter sensor 310 to determine the most suitable treatment parameters for the patient implemented by the electrodes of the portable tDCS treatment helmet 100. These treatment parameters include electrode placement, current intensity, treatment duration, etc.

[0077] like Figure 5 As shown, in a hospital treatment environment, the control unit 130 is remotely connected to the server 300 through the mobile terminal 200. At this time, the patient wears the portable tDCS treatment helmet 100, and the cathode 110 and the anode 120 are adjusted to the appropriate position by the medical staff so that each electrode corresponds to the target brain area of ​​the patient. The server 300 can receive both the treatment parameters of the portable tDCS treatment helmet 100 and the second stress physiological parameters collected by the physiological parameter sensor 310. The control unit 130 of the portable tDCS treatment helmet 100 controls the electrodes to electrically stimulate the target brain area according to the parameter mapping table.

[0078] When receiving electrical stimulation, people will produce stress physiological parameters. In a short period of time, people's stress physiological parameters are similar or consistent. This consistency or proximity indicates that the patient's physiological response to electrical stimulation is stable and predictable. When receiving electrical stimulation treatment, such as transcranial direct current stimulation (tDCS), the goal is to achieve the desired therapeutic effect by changing the neural activity in the brain area. Stress physiological parameters, such as heart rate, blood pressure, skin conductance, etc., are quantitative indicators of the human body's stress response. Changes in these parameters reflect the physiological and psychological responses of the brain and body to external stimuli.

[0079] When using a professional tDCS device, by measuring and recording the first stress physiological parameter, the patient's initial response baseline to electrical stimulation can be obtained. During the subsequent electrical stimulation process using the portable tDCS treatment helmet 100, the second stress physiological parameter measured again is compared with the initial baseline. If the difference between the two decreases, approaches or is equal, it means that the physiological response produced by the electrical stimulation is within a stable range and does not cause abnormal or excessive physiological stress response. This stability is one of the key indicators of treatment effectiveness because it indicates that the patient's brain and body are able to adapt to electrical stimulation and are more likely to benefit from it. Therefore, when the two stress physiological parameters show consistency or proximity, it can be inferred that the electrical stimulation is effective at the physiological level because it does not cause unstable or maladaptive physiological responses. This indication of effectiveness provides a scientific basis for adjusting and setting initial treatment parameters, aiming to optimize the treatment effect by precisely controlling the electrical stimulation conditions while minimizing adverse reactions or side effects. In addition, by monitoring the changes in stress physiological parameters of different treatment devices, medical staff can adjust the electrical stimulation parameters more accurately, making the treatment more personalized and further improving the safety and effectiveness of the treatment.

[0080] As described above, during the process of electrical stimulation implemented by the portable tDCS treatment helmet 100, when the second stress physiological parameter can approach or be equal to the first stress physiological parameter, it means that the electrical stimulation implemented by the portable tDCS treatment helmet 100 is effective for the patient. The server 300 determines the electrical stimulation parameters implemented by the portable tDCS treatment helmet 100 at this moment as the initial treatment parameters. The present invention provides an effective reference for setting the initial treatment parameters based on the stress physiological parameters, which can reduce the setting error of the initial treatment parameters.

[0081] Preferably, the server 300 compares the treatment parameters of the professional tDCS device associated with the first stress physiological parameter with the initial treatment parameters to determine whether the difference between the two is within the allowable error range. If the difference between the two exceeds the allowable error range, the server 300 needs to re-determine the second stress physiological parameter or adjust the initial treatment parameter until the initial treatment parameters and the corresponding second stress physiological parameters that can be implemented by the portable tDCS treatment helmet 100 are compared with the treatment parameters of the professional tDCS device and the corresponding first stress physiological parameters, and both types of differences are within the allowable error range. This process ensures the personalization and optimization of the treatment parameters and improves the success rate of the treatment.

[0082] like Figure 5As shown, in the process of the professional transcranial direct current stimulation device treating the patient according to the best treatment plan, the server 300 is connected to the image acquisition device 320. The image acquisition device 320 is, for example, an infrared camera or a camera. The image acquisition device 320 acquires three-dimensional image data of the patient's head. An artificial intelligence model is provided in the server 300. The artificial intelligence model determines the first coordinate parameter of the electrode stimulation position based on the received three-dimensional head image data. The server 300 calculates the second coordinate parameter of the electrode for implementing electrical stimulation based on the electrode distribution characteristics of the portable tDCS treatment helmet 100 fed back by the mobile terminal 200 and the three-dimensional head data of the patient, thereby achieving the effect of electrical stimulation at the head position corresponding to the first coordinate parameter.

[0083] Since the portable tDCS treatment helmet 100 has different adaptability to the patient's head, whether the electrode can stimulate the treatment area is the core issue of the treatment. The portable tDCS treatment helmet 100 has structural differences from professional transcranial direct current stimulation equipment, so the present invention obtains the second coordinate parameter of the portable tDCS treatment helmet 100 for effective operation by calculating the coordinate parameter of the stimulation, so as to improve the effectiveness of the stimulation of the treatment area.

[0084] According to a preferred embodiment, the server 300 periodically requests the mobile terminal 200 for request information of the meter data 210 , and the mobile terminal 200 generates reminder information 220 of the meter data 210 based on the request information, so that the patient inputs the meter data 210 through the mobile terminal 200 .

[0085] When at home, patients easily forget to input the scale data 210. Most patients need to be reminded passively before actively inputting the scale data 210. The present invention obtains the scale data 210 through the reminder information 220, ensuring that the scale data 210 can be obtained in a timely manner.

[0086] According to a preferred embodiment, the mobile terminal 200 is connected to at least one physiological parameter sensor 310. The mobile terminal 200 associates the second stress physiological parameter during home treatment with the corresponding treatment parameter and sends it to the server 300.

[0087] Associating the second stress physiological parameter with the treatment parameter helps the server 300 analyze whether the electrode has electrically stimulated the patient according to the treatment parameter, thereby reducing the situation where treatment information is analyzed incorrectly and also reducing the situation where ineffective work of the portable tDCS treatment helmet 100 is analyzed as effective work.

[0088] According to a preferred embodiment, when at home, the server 300 analyzes the validity of the scale data 210 based on the second stress physiological parameter fed back by the mobile terminal 200. When the validity of the scale data 210 is lower than a preset threshold, the server 300 sends request information for the scale data 210 and reminder information 220 related to the validity to the mobile terminal 200 again.

[0089] When patients input the scale data 210, they often input inaccurate data due to their non-professional background or lack of medical knowledge. Some patients even input false scale data 210. This requires the server 300 to be able to determine the validity of the scale data 210 in a timely manner, thereby prompting or guiding the patient to provide accurate scale data 210.

[0090] Specifically, the following method can be used to judge the validity of the scale data 210 used by the portable tDCS treatment helmet 100. First, define the indicators of the validity of the scale data 210 (such as completion, consistency and logic) and set the minimum acceptance threshold for each indicator. The scale data 210 filled in by the patient is collected regularly through the mobile terminal 200, and the server 300 preliminarily analyzes these scale data 210, such as the scores and change trends of pain intensity and its impact on daily activities and sleep. Next, the validity of the scale data 210 is evaluated by applying the preset threshold, and the data authenticity and accuracy are further verified in combination with the patient's physiological parameters (such as heart rate, blood pressure). If the validity of the scale data 210 is lower than the threshold, the server 300 will send a request to the mobile terminal 200 to re-fill the scale and attach a reminder message 220. According to the validity results of the scale data 210, the treatment plan is appropriately adjusted. This process should be repeated regularly to continuously monitor the validity of the scale data 210 and ensure the optimization of the treatment strategy, so as to provide the most appropriate treatment plan for the patient. This approach ensures the quality of data collection and adaptability of treatment plans through regular evaluation and feedback mechanisms.

[0091] According to a preferred embodiment, when the validity of the scale data 210 is not less than a preset threshold, the server 300 analyzes the treatment effect of the current best treatment plan based on the scale data 210 and determines the treatment plan for the next stage. When the scale data 210 is judged to be valid, the result obtained by the server 300 based on the scale data 210 is accurate.

[0092] According to a preferred embodiment, the mobile terminal 200 sends the treatment parameters of the portable tDCS treatment helmet 100 to the server 300 according to a preset cycle, so that the server 300 can judge whether the patient implements the best treatment plan, thereby reducing the probability of erroneous analysis of the treatment effect of the best treatment plan. Some patients may not actively follow the treatment plan, such as refusing to accept electrode stimulation or not wearing the portable tDCS treatment helmet 100 at the prescribed time. Such behavior will undoubtedly reduce the effectiveness of the treatment plan. Therefore, the server 300 should master the treatment parameters of the portable tDCS treatment helmet 100, such as operating time, electrical stimulation frequency and other information, to confirm whether the portable tDCS treatment helmet 100 is running according to the treatment plan.

[0093] According to a preferred embodiment, when the treatment parameters of the portable tDCS treatment helmet 100 need to be corrected, the server 300 sends a correction reminder message to the mobile terminal 200 so that the patient can take the portable tDCS treatment helmet 100 to the hospital to recalibrate the treatment parameters. After long-term use or collision or impact, the electrodes of the portable tDCS treatment helmet 100 may be misplaced, resulting in inaccurate treatment areas, thereby weakening the treatment effect. Therefore, the server 300 needs to promptly detect abnormal operation and issue correction reminder messages in a timely manner.

[0094] According to a preferred embodiment, when the treatment parameters of the portable tDCS treatment helmet 100 statistically determined by the server 300 deviate from the treatment parameters determined last time, the server 300 determines that the portable tDCS treatment helmet 100 needs to be calibrated or repaired. The server 300 will analyze the data deviation to quickly detect the operation abnormality and issue a correction reminder.
