Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, for example, to a charging control method of an external charger, an external charger, a pulse generator and a computer-readable storage medium. Background Art

[0002] With the development of science and technology and social progress, patients are eager to improve their quality of life through various treatment methods, among which the application prospects of implantable medical systems are very broad. An implantable neural electrical stimulation system is a type of implantable medical system. Taking an implantable neural electrical stimulation system as an example, it includes a stimulator implanted in the patient's body (i.e., an implantable neural stimulator) and a programmable device set outside the patient's body. The stimulator includes a pulse generator and an electrode, and the stimulator can provide patients with refined electrical stimulation therapy with controllable parameters.

[0003] The pulse generator needs to be wirelessly charged with an external charger, which transmits energy by generating and capturing electromagnetic fields. Patients may use different charging postures when charging the pulse generator with an external charger at different times, such as standing, sitting, or lying down. The distance or angle between the external charger and the pulse generator is also different in different postures, which affects the charging efficiency.

[0004] Based on this, the present application provides a charging control method of an external charger, an external charger, a pulse generator and a computer-readable storage medium to solve the problems existing in the above-mentioned technologies. Summary of the invention

[0005] The purpose of the present application is to provide a charging control method for an external charger, an external charger, a pulse generator and a computer-readable storage medium to solve the problem of unsatisfactory charging efficiency under different charging postures.

[0006] The purpose of this application is achieved by the following technical solutions:

[0007] In a first aspect, the present application provides a charging control method of an external charger, wherein the external charger is used to charge a pulse generator, and the method comprises:

[0008] Acquiring first posture information of the patient through the external charger;

[0009] According to the first posture information, determining whether charging parameters of the external charger need to be adjusted, the charging parameters including one or more of a resonant voltage, a resonant frequency, a resonant matching capacitance, a coil position parameter, and a coil angle parameter;

[0010] When the charging parameters of the external charger need to be adjusted, the charging parameters of the external charger are updated according to the first posture information.

[0011] The beneficial effect of this technical solution is that the first posture information of the patient can be obtained through sensors such as accelerometers of the external charger to know whether the patient is currently standing, sitting or lying down. A judgment can be made based on the first posture information obtained in real time to determine whether the current charging parameters are suitable for the user's current posture. The charging parameters may include resonant voltage, resonant frequency, resonant matching capacitance, coil position parameters, and coil angle parameters, etc., to more comprehensively adjust the external charger and reduce the negative impact of (patient posture) on the charging efficiency of the charger. If it is determined that the charging parameters need to be adjusted under the current posture, the corresponding parameters can be updated according to the first posture information, that is, the resonant voltage, resonant frequency, resonant matching capacitance, coil position parameters, and coil angle parameters, etc. are adjusted according to the patient's posture to achieve a high-efficiency charging effect.

[0012] Compared with the related technology that when the external charger is not efficient in charging the pulse generator of the patient, the patient needs to adjust his posture (for example, from a supine posture to a standing posture), and then observe whether the charging efficiency is improved after the posture adjustment, the present technical solution can dynamically adjust the charging parameters according to the patient's posture information. Under different postures of the patient, the distance, angle and other conditions between the charger and the pulse generator may be different, affecting the energy transmission efficiency. By acquiring the first posture information in real time and adjusting the charging parameters accordingly, it can be ensured that the pulse generator of the patient can be efficiently charged under different postures. That is, the present embodiment has the following advantages: on the one hand, dynamically adjusting the charging parameters according to the patient's posture can improve the efficiency of energy transmission and reduce energy loss, thereby achieving a faster and more efficient charging process. On the other hand, the patient may use the external charger to charge the pulse generator in different postures. Adjusting the charging parameters according to the real-time posture information can meet the patient's charging needs and improve the patient's convenience of use. On the other hand, the present technical solution can simultaneously optimize the charging efficiency and adapt to the patient's different postures, instead of asking the patient to change his posture to avoid reduced charging efficiency, which can improve the patient's satisfaction with the use of implantable medical devices and make them more willing to use and rely on implantable medical devices.

[0013] In some possible implementations, before determining the charging parameter, the following steps are further included:

[0014] Acquiring second posture information of the patient through the pulse generator;

[0015] The determining, according to the first posture information, whether a charging parameter of the external charger needs to be adjusted includes:

[0016] Determining whether the external charger meets a detection condition according to the first posture information and the second posture information;

[0017] When the external charger meets the detection condition, the charging parameters of the external charger are judged.

[0018] The beneficial effect of the technical solution is that before judging the charging parameters, the second posture information is obtained, and the detection conditions are preliminarily judged according to the first posture information and the second posture information. In this embodiment, not only the first posture information of the patient is obtained through the external charger, but also the second posture information of the patient is obtained through the pulse generator, and the first and second posture information are used to judge whether the charger meets the detection conditions. Only when the detection conditions are met, the judgment of the charging parameters of the external charger is performed. On the one hand, the second posture information is introduced to more accurately judge whether the charging parameters need to be adjusted to achieve more efficient charging. On the other hand, through the judgment step of the detection conditions, the charging parameters are judged and adjusted only when the charger meets the detection conditions, which can reduce the misadjustment caused by the temporary position change of the external charger. On the other hand, combining the first and second posture information can more comprehensively understand the patient's activity mode and posture changes, so as to better optimize the charging parameters. In summary, this implementation combines the first and second posture information and the step of judging the detection conditions to adjust the charging parameters in a more accurate and comprehensive manner, thereby improving the efficiency, accuracy and charging experience of the patient.

[0019] In some possible implementations, judging whether the external charger meets the detection condition according to the first posture information and the second posture information includes:

[0020] Acquire a matching score between the external charger and the pulse generator according to the first posture information and the second posture information;

[0021] Whether the external charger meets the detection conditions is determined by the matching score and a preset matching threshold.

[0022] The beneficial effect of the technical solution is that the matching degree between the charger and the pulse generator is evaluated based on the first and second posture information to determine the degree of correspondence between the charger and the pulse generator. Then, the matching score obtained from the first and second posture information is compared with a preset matching threshold. According to the comparison between the matching score and the threshold, it is determined whether the external charger meets the detection condition. It can be considered that if the matching score reaches or exceeds the preset matching threshold, then the external charger meets the detection condition.

[0023] On the one hand, by calculating the matching score to determine the matching degree between the external charger and the pulse generator according to the actual situation, personalized adaptive charging is achieved. On the other hand, through the matching threshold, the above charging control method can be more flexibly adapted to different charging scenarios. It can be understood that the preset matching threshold allows the matching requirements to be adjusted to a certain extent, thereby reducing the charging interruption caused by slightly insufficient matching under specific conditions. On the other hand, by considering the matching degree between the charger and the pulse generator, the risk of charging parameter adjustment can be reduced. In summary, by comparing the matching score and the matching threshold, a more intelligent factor is introduced for the charging parameter adjustment of the external charger, so that the above charging control method can adapt to different charging scenarios.

[0024] In some possible implementations, when the external charger does not meet the detection conditions, the method further includes the steps of:

[0025] Acquire a reference charging parameter of the external charger according to the second posture information;

[0026] A first similarity between the reference charging parameter and the current charging parameter is obtained, and when the first similarity is not less than a preset similarity, the charging parameter of the external charger is updated according to the reference charging parameter.

[0027] The beneficial effect of this technical solution is that when the external charger does not meet the detection conditions, the reference charging parameters can also be obtained based on the second posture information, and the charging parameters can be updated according to the reference charging parameters. Specifically, when the external charger does not meet the detection conditions, that is, when the matching degree between the two does not reach the preset threshold, the reference charging parameters can also be obtained based on the second posture information, which is used as a reference for the current charging parameters. A first similarity between the current charging parameters and the reference charging parameters is obtained, and the first similarity can be calculated by comparing the differences between the parameters to quantify the similarity between the current charging parameters and the reference charging parameters. If the first similarity is not less than the preset similarity threshold, that is, the similarity between the current charging parameters and the reference charging parameters is high enough, the current charging parameters are updated according to the reference charging parameters in the hope of optimizing the charging effect. It can be considered that the above parameter update adjustment is a fine-tuning of the current charging parameters.

[0028] On the one hand, fine-tuning of charging parameters can make the charging parameters closer to the optimal state without destroying the overall stability, thereby achieving more efficient energy transmission and charging effects. On the other hand, the fine-tuning mechanism can automatically adapt to different charging scenarios and patient postures according to actual conditions, providing a charging experience that better meets the needs.

[0029] In summary, when the external charger does not meet the detection conditions, the matching score does not reach or exceed the preset matching threshold. This is generally because the matching degree between the external charger and the pulse generator is not high due to the temporary position change of the external charger. In this case, the charging parameters are updated according to the first posture information obtained by the external charger, which is prone to misadjustment. In this case, the reference charging parameters are obtained based on the second posture information, and the charging parameters are fine-tuned according to the reference charging parameters, which has a high level of intelligence.

[0030] In some possible implementations, when the charging parameters of the external charger need to be adjusted, the method further includes:

[0031] Counting the number of times the charging parameters are adjusted to obtain a cumulative number;

[0032] When the accumulated number is greater than the preset accumulated number, a prompt message is sent to the user device, and the accumulated number is cleared; the prompt message is used to indicate that the current charging parameters do not match the external charger and the pulse generator.

[0033] The beneficial effect of this technical solution is that the accumulated number of adjustments is compared with the preset accumulated number of times. If the accumulated number exceeds the preset number of times, it means that multiple charging parameter adjustments have occurred within a period of time. When the accumulated number exceeds the preset number of times, a prompt message is sent to the user device to remind the user that there may be a mismatch between the current charging parameters and the external charger and pulse generator. After sending the prompt message to the user, the accumulated number will be cleared to start the next stage of counting. By accumulating the number of adjustments and sending prompt messages, the user can be reminded that the current charging parameters may not match the external charger and pulse generator, attracting the user's attention and avoiding harm to the patient. On the other hand, the preset accumulated number of times can help prevent frequent charging parameter adjustments, thereby reducing the possibility of misoperation. The counting and prompt mechanism can help users better understand the adjustment of the charging parameters.

[0034] Some beneficial effects of the technical solution are: in a possible implementation, updating the charging parameters of the external charger according to the first posture information includes:

[0035] Inputting the first posture information into a parameter configuration model to obtain a plurality of recommended charging parameters corresponding to the external charger;

[0036] The second similarity between each of the recommended charging parameters and the current charging parameters is obtained, and the recommended charging parameter corresponding to the highest second similarity is selected to update the charging parameter of the external charger.

[0037] The beneficial effect of this technical solution is that by calculating the similarity between different recommended parameters and current parameters, the recommended parameters most similar to the current parameters are automatically selected to update the charging parameters, and by selecting more similar recommended parameters to update the charging parameters, the current posture can be matched more accurately, thereby improving energy transmission efficiency.

[0038] In a second aspect, the present application further provides an external charger, the external charger is used to charge the pulse generator, the external charger includes a coil, a memory and a processor;

[0039] The coil is used to transfer electrical energy from the external charger to the pulse generator;

[0040] The memory stores a computer program, and when the processor executes the computer program, the steps of the charging control method for the external charger according to any one of the first aspects are implemented.

[0041] Some possible implementations also include:

[0042] A posture recognition module, used for acquiring first posture information of the patient;

[0043] A posture adjustment module is used to adjust the charging parameters of the external charger according to the first posture information, and the charging parameters include one or more of the resonant voltage, the resonant frequency, the resonant matching capacitance, the coil position parameter and the coil angle parameter.

[0044] In some possible implementations, the posture recognition module includes one or more sensors, and the one or more sensors are used to acquire a set of sensor data to recognize the posture of the patient.

[0045] In some possible implementations, the posture adjustment module includes an adjustment motor, and the adjustment motor is used to adjust the position and / or angle of the coil of the external charger according to the charging parameters so that the coil and the pulse generator remain in a parallel state.

[0059] The technical solution in the present application will be described below in conjunction with the drawings and specific implementation methods of the specification of the present application. It should be noted that, under the premise of no conflict, the various implementation methods or technical features described below can be arbitrarily combined to form a new implementation method.

[0060] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any implementation or design scheme described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other implementations or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0061] The first, second, etc. descriptions appearing in the embodiments of the present application are only used for illustration and distinction of the description objects. There is no order, nor does it indicate any special limitation on the quantity in the embodiments of the present application, and cannot constitute any limitation on the embodiments of the present application.

[0062] The following is a brief description of the technical field and related terms of the embodiments of the present application.

[0063] Implantable medical systems include implantable neural stimulation systems, implantable cardiac stimulation systems (also known as pacemakers), implantable drug delivery systems (IDDS), and lead switching systems. Examples of implantable neural stimulation systems include deep brain stimulation (DBS), implantable cortical nerve stimulation (CNS), implantable spinal cord stimulation (SCS), implantable sacral nerve stimulation (SNS), and implantable vagus nerve stimulation (VNS).

[0064] The implantable neural electrical stimulation system includes a stimulator implanted in the patient's body (i.e., an implantable neural stimulator) and a programmable device disposed outside the patient's body. In other words, the stimulator is a medical device, or in other words, the medical device includes the stimulator. The relevant neural regulation technology mainly implants electrodes (electrodes, for example, in the form of electrode wires) in specific parts of the tissues of the organism (i.e., target points) through stereotactic surgery, and emits discharge pulses to the target points through the electrodes to regulate the electrical activity and function of the corresponding neural structures and networks, thereby improving symptoms and relieving pain.

[0065] As an example, DBS includes an IPG (Implantable Pulse Generator), an extension wire and an electrode wire, and the IPG is connected to the electrode wire via the extension wire. The IPG is implanted in the patient's body, for example, in the patient's chest or other body parts.

[0066] As another example, DBS includes an IPG and an electrode lead, and the IPG is directly connected to the electrode lead. The IPG is implanted in the patient's head, for example, a groove is made in the patient's skull, and then the IPG is installed in the groove of the skull. In this case, the IPG may not protrude from the outer surface of the skull, or may partially protrude from the outer surface of the skull.

[0067] Among them, IPG responds to the program-controlled instructions sent by the program-controlled device, relying on sealed batteries and circuits to provide controllable electrical stimulation therapy (or electrical stimulation energy) to the tissues in the body. When the battery is low, the battery needs to be charged, and the method for charging the battery can be to use electromagnetic induction coil wireless charging to charge through human skin or other epidermal tissues. IPG delivers one or more controllable specific electrical stimulations to specific areas of the tissue in the body through electrode wires.

[0068] In some embodiments, the extension lead is used in conjunction with the IPG as a transmission medium for electrical stimulation, and transmits the electrical stimulation generated by the IPG to the electrode lead.

[0069] In some embodiments, the electrical stimulation may be delivered in the form of a pulse signal or in the form of a non-pulse signal. For example, the electrical stimulation may be delivered as a signal having various waveform shapes, frequencies, and amplitudes. Thus, the electrical stimulation in the form of a non-pulse signal may be a continuous signal, which may have a sinusoidal waveform or other continuous waveform.

[0070] After receiving the electrical stimulation transmitted by the IPG or the extension wire, the electrode wire delivers the electrical stimulation to a specific area of ​​the tissue in the body through a plurality of electrode contacts. The stimulator is provided with, for example, one or more electrode wires on one side or both sides, and a plurality of electrode contacts are provided on the electrode wire, and the electrode contacts can be arranged uniformly or non-uniformly in the circumferential direction of the electrode wire. As an example, the electrode contacts can be arranged in an array of 4 rows and 3 columns (a total of 12 electrode contacts) in the circumferential direction of the electrode wire. The electrode contacts can include stimulation electrode contacts and / or collection electrode contacts. The electrode contacts can be in the shape of sheets, rings, dots, etc., for example.

[0071] In some embodiments, the stimulated in vivo tissue may be the patient's brain tissue, and the stimulated site may be a specific site of the brain tissue. When the patient's disease type is different, the stimulated site is generally different, and the number of stimulation contacts (single source or multiple sources), the use of one or more (single channel or multiple channels) of specific electrical stimulation, and the stimulation parameters (values) are also different.

[0072] The embodiments of the present application do not limit the types of diseases that can be used, and they can be the types of diseases that deep brain stimulation (DBS), spinal cord stimulation (SCS), sacral nerve stimulation, gastric stimulation, peripheral nerve stimulation, and functional electrical stimulation can be used for. Among them, the types of diseases that DBS can be used to treat or manage include, but are not limited to: spastic diseases (e.g., epilepsy), pain, migraine, mental illness (e.g., major depressive disorder (MDD)), bipolar disorder, anxiety, post-traumatic stress disorder, mild depression, obsessive-compulsive disorder (OCD), behavioral disorders, mood disorders, memory disorders, mental state disorders, movement disorders (e.g., essential tremor or Parkinson's disease), Huntington's disease, Alzheimer's disease, drug addiction, autism or other neurological or psychiatric diseases and injuries.

[0073] In the embodiment of the present application, when the programmable device and the stimulator establish a programmable connection, the programmable device can be used to adjust one or more stimulation parameters of the stimulator (or one or more stimulation parameters of the pulse generator, different stimulation parameters correspond to different electrical stimulations), and the stimulator can also sense the patient's electrophysiological activities to collect electrophysiological signals, and the collected electrophysiological signals can be used to continue to adjust the stimulation parameters of the stimulator, thereby realizing closed-loop control (or adaptive adjustment) of the stimulation parameters.

[0074] The stimulation parameters may include at least one of the following: the electrode contact identification used to deliver electrical stimulation (for example, electrode contact #2 and electrode contact #3), frequency (for example, the number of electrical stimulation pulse signals within a unit time of 1s, in Hz), pulse width (the duration of each pulse, in μs), amplitude (generally expressed in voltage, that is, the intensity of each pulse, in V), timing (for example, it can be continuous or burst, and burst refers to discontinuous timing behavior composed of multiple processes), stimulation mode (including one or more of current mode, voltage mode, timed stimulation mode and cyclic stimulation mode), upper and lower limits controlled by the doctor (the range that can be adjusted by the doctor) and upper and lower limits controlled by the patient (the range that can be adjusted autonomously by the patient).

[0075] In some embodiments, various stimulation parameters of the stimulator can be adjusted in current mode or voltage mode.

[0076] Programmable devices may include doctor programmable devices (i.e. programmable devices used by doctors) and / or patient programmable devices (i.e. programmable devices used by patients). Doctor programmable devices are, for example, tablet computers, laptop computers, desktop computers, mobile phones and other intelligent terminal devices equipped with programmable software. Patient programmable devices are, for example, tablet computers, laptop computers, desktop computers, mobile phones and other intelligent terminal devices equipped with programmable software. Patient programmable devices may also be other electronic devices with programmable functions (e.g., chargers with programmable functions, electrophysiological acquisition devices, etc.).

[0077] The embodiment of the present application does not restrict the data interaction between the doctor's programmable device and the stimulator. When the doctor performs remote programming, the doctor's programmable device can interact with the stimulator through the server and the patient's programmable device. When the doctor performs offline programming with the patient face to face, the doctor's programmable device can interact with the stimulator through the patient's programmable device, and the doctor's programmable device can also interact with the stimulator directly.

[0078] In some embodiments, the patient programmable device may include a host (communicating with a server) and a slave (communicating with a stimulator), and the host and the slave are communicatively connected. Among them, the doctor programmable device can exchange data with the server through a 3G / 4G / 5G network, the server can exchange data with the host through a 3G / 4G / 5G network, the host can exchange data with the slave through a Bluetooth protocol / WIFI protocol / USB protocol, the slave can exchange data with the stimulator through a 401MHz-406MHz working frequency band / 2.4GHz-2.48GHz working frequency band, and the doctor programmable device can directly exchange data with the stimulator through a 401MHz-406MHz working frequency band / 2.4GHz-2.48GHz working frequency band.

[0079] The following will first describe the charging control method for an external charger, and then describe the related devices.

[0080] Method Embodiment

[0081] See also Figure 1 , Figure 1 It is a flow chart of a charging control method of an external charger provided in an embodiment of the present application.

[0082] This embodiment provides a charging control method of an external charger, wherein the external charger is used to charge a pulse generator, and the method includes:

[0083] Step S101, obtaining first posture information of a patient through the external charger;

[0084] Step S102, judging whether charging parameters of the external charger need to be adjusted according to the first posture information; the charging parameters include one or more of a resonant voltage, a resonant frequency, a resonant matching capacitance, a coil position parameter, and a coil angle parameter;

[0085] Step S103: When the charging parameters of the external charger need to be adjusted, the charging parameters of the external charger are updated according to the first posture information.

[0086] Thus, the first posture information of the patient can be obtained through sensors such as accelerometers of the external charger to know whether the patient is currently standing, sitting or lying down in different postures. A judgment can be made based on the first posture information obtained in real time to determine whether the current charging parameters are suitable for the user's current posture. The charging parameters may include resonant voltage, resonant frequency, resonant matching capacitance, coil position parameters, and coil angle parameters, etc., to more comprehensively adjust the external charger and reduce the negative impact of (patient posture) on the charging efficiency of the charger. If it is determined that the charging parameters need to be adjusted under the current posture, the corresponding parameters can be updated according to the first posture information, that is, the resonant voltage, resonant frequency, resonant matching capacitance, coil position parameters, and coil angle parameters, etc., are adjusted according to the patient's posture to achieve a high-efficiency charging effect.

[0087] Compared with the related art, when the external charger is not efficient in charging the patient's pulse generator, the patient needs to adjust his posture (for example, from a supine posture to a standing posture), and then observe whether the charging efficiency is improved after the posture adjustment. The present technical solution can dynamically adjust the charging parameters according to the patient's posture information. Under different postures of the patient, the distance, angle and other conditions between the external charger and the pulse generator may be different, affecting the energy transmission efficiency. By acquiring the first posture information in real time and adjusting the charging parameters accordingly, it can be ensured that the patient's pulse generator can be efficiently charged in different postures. That is, this embodiment has the following advantages: On the one hand, dynamically adjusting the charging parameters according to the patient's posture can improve the efficiency of energy transmission and reduce energy loss, thereby achieving a faster and more efficient charging process. On the other hand, the patient may use the external charger to charge the pulse generator in different postures. Adjusting the charging parameters according to the real-time posture information can meet the patient's charging needs and improve the patient's convenience of use. On the other hand, the present technical solution can simultaneously optimize the charging efficiency and adapt to different postures of patients, rather than requiring patients to change their posture to avoid reduced charging efficiency. This can improve patients' satisfaction with the use of implantable medical devices and make them more willing to use and rely on implantable medical devices.

[0088] As an example, patient A has a stimulator implanted for treatment and needs to be charged through an external charger implanted in the chest. The external charger has a built-in accelerometer sensor, which can obtain the first posture information of patient A during the charging process. The first posture information indicates that patient A is standing and leaning forward at this time, while the current charging parameters are suitable for lying flat. It can be considered that the forward leaning posture will increase the distance between the external charger and the pulse generator, and the current charging parameters need to be adjusted. According to the first posture information, the resonant voltage is adjusted from 8V to 12V.

[0089] Among them, the first posture information and the second posture information mentioned below are used to indicate the posture of the patient, such as standing, sitting, lying down, etc. The sensor in the external charger can obtain data such as the tilt angle, the distance between the external charger and the pulse generator, and the above data can be analyzed to obtain the patient's current posture. Generally speaking, the first posture information obtained by the external charger is basically the same as the second posture information obtained by the pulse generator, but in special circumstances, such as when the patient is exercising vigorously, the external charger may be temporarily separated from the patient, and the first posture information and the second posture information are quite different in this case.

[0090] The adjustment of the charging parameters, for example, is to adjust at least one of the resonant voltage, the resonant frequency, the resonant matching capacitance, the coil position parameter and the coil angle parameter.

[0091] The resonant voltage is the voltage used to generate the resonant electromagnetic field. It can be considered that the distance between the patient and the external charger may change in different postures, which in turn affects the propagation and intensity of the electromagnetic field. Adjusting the resonant voltage can ensure that the intensity of the electromagnetic field is appropriate at different distances to achieve effective energy transfer.

[0092] The resonant frequency refers to the frequency at which the electromagnetic field resonates. By adjusting the resonant frequency, the resonant state between the electromagnetic field and the pulse generator can be maintained, thereby improving the energy transmission efficiency.

[0093] The resonant matching capacitor is used to adjust the matching of the resonant circuit to ensure maximum energy transfer. Adjusting the resonant matching capacitor according to the posture can maintain the matching of the circuit and maintain the energy transfer efficiency.

[0094] Changes in the patient's posture may cause changes in the position and angle of the coil between the external charger and the pulse generator. The position and angle of the coil will affect the coupling of the electromagnetic field and the energy transmission effect. By adjusting the position and angle of the coil, the optimal coupling state between the coils can be maintained, thereby improving the energy transmission efficiency. Among them, a micro motor can be used in conjunction with transmission components such as gears to move the coil from a first position to a second position to shorten the distance of the coil relative to the patient; a micro motor can also be used in conjunction with transmission components such as gears to adjust the angle of the coil so that the coils inside the neurostimulator and the charger remain in a parallel state, thereby maximizing the charging efficiency.

[0095] As an example:

[0096] For the resonant voltage, adjust from 10V to 12V;

[0097] For the resonant frequency, adjust from 100kHz to 105kHz;

[0098] For the resonant matching capacitor, adjust from 50pF to 55pF;

[0099] The coil position parameters and coil angle parameters were adjusted from a distance of 0.5 cm relative to the patient's chest and an angle of -10 degrees to a distance of 0.4 cm relative to the patient's chest and an angle of -5 degrees.

[0100] In a specific application, there may be multiple charging parameter groups, each of which corresponds to a patient's posture. Updating the charging parameters of the external charger can be understood as taking the charging parameters in the charging parameter group corresponding to the posture indicated by the first posture information as the current charging parameters. The advantage is that the charging parameters are updated quickly and with low calculation complexity.

[0101] See also Figure 2 and Figure 3 , Figure 2 is a flow chart of another charging control method of an external charger provided in an embodiment of the present application, Figure 3 It is a flow chart of executing charging parameter judgment provided in an embodiment of the present application.

[0102] In some embodiments, before determining the charging parameters, the following steps may also be performed:

[0103] Step S104, obtaining the second posture information of the patient through the pulse generator. The pulse generator may be provided with at least one sensor, which can be used to obtain data such as the tilt angle and the distance between the external charger and the pulse generator, and analyze the above data to obtain the current posture of the patient.

[0104] The determining, based on the first posture information, whether the charging parameters of the external charger need to be adjusted (i.e., step S102) may include:

[0105] Step S201, judging whether the external charger meets the detection condition according to the first posture information and the second posture information;

[0106] Step S202: When the external charger meets the detection conditions, the charging parameters of the external charger are determined.

[0107] Thus, before judging the charging parameters, the second posture information is obtained, and a preliminary judgment of the detection conditions is made based on the first posture information and the second posture information. In this embodiment, not only the first posture information of the patient is obtained through the external charger, but also the second posture information of the patient is obtained through the pulse generator, and the first and second posture information are used to judge whether the charger meets the detection conditions. Only when the detection conditions are met, the judgment of the charging parameters of the external charger is performed. On the one hand, the second posture information is introduced to more accurately judge whether the charging parameters need to be adjusted to achieve more efficient charging. On the other hand, through the judgment step of the detection conditions, the charging parameters are judged and adjusted only when the charger meets the detection conditions, which can reduce the misadjustment caused by the temporary position change of the external charger. On the other hand, combining the first and second posture information can more comprehensively understand the patient's activity mode and posture changes, so as to better optimize the charging parameters. In summary, this implementation combines the first and second posture information and the step of judging the detection conditions to adjust the charging parameters in a more accurate and comprehensive manner, thereby improving the efficiency, accuracy and charging experience of the patient.

[0108] This embodiment does not limit the method for determining whether the external charger meets the detection conditions, which can be any of the following:

[0109] Compare the difference between the pitch angles of the external charger and the pulse generator. If the difference exceeds the preset pitch angle difference value, it is judged that the detection condition is not met;

[0110] Calculate the matching score of the first posture information and the second posture information, and compare the score with the matching threshold. If the score is lower than the matching threshold, it is determined that the detection condition is not met.

[0111] Among them, the pitch angle refers to the rotation angle of an object relative to the horizontal plane, usually with the forward and backward tilt as the positive direction. The pitch angle is used to describe the degree of rotation of an object around the horizontal axis in three-dimensional space. In this application, the pitch angle is measured based on the horizontal plane, with a positive value when the object is tilted upward and a negative value when it is tilted downward. In specific applications, the above definition can also be made using the tilt angle, etc. This application does not limit the selection of coil angle parameters.

[0112] In a specific application, the above method can be performed in the order of step S101, step S104, step S102 and step S103. Similarly, step S101 and step S104 can be performed simultaneously, or step S104 can be performed before step S101. This embodiment does not limit the execution order of step S101 and step S104.

[0113] See also Figure 4 , Figure 4It is a flow chart of determining detection conditions provided in an embodiment of the present application.

[0114] In some embodiments, judging whether the external charger meets the detection condition according to the first posture information and the second posture information (ie, step S201) may include:

[0115] Step S301, obtaining a matching score between the external charger and the pulse generator according to the first posture information and the second posture information;

[0116] Step S302: judging whether the external charger meets the detection conditions according to the matching score and the preset matching threshold.

[0117] Thus, the matching degree between the charger and the pulse generator is evaluated based on the first and second posture information to determine the degree of correspondence between the charger and the pulse generator. Then, the matching score obtained from the first and second posture information is compared with a preset matching threshold. Based on the comparison between the matching score and the threshold, it is determined whether the external charger meets the detection condition. It can be considered that if the matching score reaches or exceeds the preset matching threshold, then the external charger meets the detection condition.

[0118] On the one hand, by calculating the matching score to determine the matching degree between the external charger and the pulse generator according to the actual situation, personalized adaptive charging is achieved. On the other hand, through the matching threshold, the above charging control method can be more flexibly adapted to different charging scenarios. It can be understood that the preset matching threshold allows the matching requirements to be adjusted to a certain extent, thereby reducing the charging interruption caused by slightly insufficient matching under specific conditions. On the other hand, by considering the matching degree between the charger and the pulse generator, the risk of charging parameter adjustment can be reduced. In summary, by comparing the matching score and the matching threshold, a more intelligent factor is introduced for the charging parameter adjustment of the external charger, so that the above charging control method can adapt to different charging scenarios.

[0119] The present application does not limit the form of expression of the matching score, which may be, for example, 90 points, 100 points, 80%, A or D, etc.

[0120] The matching score can be obtained by using a similarity calculation method (such as Euclidean distance, cosine similarity, etc.) to compare the parameters of the first posture information and the second posture information, calculate the similarity of each parameter, and then perform standard deviation calculation based on all the calculated similarity values ​​to obtain the matching score.

[0121] The present application does not impose any restrictions on the matching threshold, which is a value preset by the user, such as 91 points, 100 points or 85%.

[0122] In some embodiments, a matching threshold can be obtained in real time according to the second posture information, and the matching threshold obtained in real time is used as a preset matching threshold. For example, when the second posture information indicates that the patient's posture is standing and slightly leaning forward, the matching threshold is set to 0.95. When the second posture information indicates that the patient's posture is standing and slightly leaning backward, the matching threshold is set to 0.97.

[0123] As an example, assume that patient B, who uses an implantable neurostimulator, has different postures at different times. Patient C uses an external charger to charge the device, and the external charger adjusts the matching threshold according to different posture information to optimize the charging effect.

[0124] In the morning, when patient B uses the external charger to charge, the second posture information indicates that the posture of patient B is sitting. In this posture, in order to ensure that the charger can stably transmit energy, the matching threshold is set to 0.90.

[0125] In the afternoon, when patient B uses an external charger to charge, the second posture information indicates that patient B is lying down. The lying down posture may reduce the efficiency of energy transmission, so the matching threshold obtained in real time is set to 0.85 to ensure the stability and efficiency of charging.

[0126] At night, when patient B is charging with the external charger, the second posture information indicates that patient B is standing upright. In this case, in order to take full advantage of the good fit between the external charger and the patient in the upright posture, the matching threshold is set to 0.95 to reduce the adjustment frequency of the charging information.

[0127] By setting different matching thresholds at different times and postures, the charger can adjust the charging parameters according to the user's actual situation to optimize energy transmission efficiency and ensure charging stability. This personalized matching threshold setting can provide a charging experience that better meets user needs while maintaining a balance in charging efficiency under different postures.

[0128] See also Figure 5 , Figure 5 It is a schematic diagram of a flow chart of updating charging parameters provided in an embodiment of the present application.

[0129] In some embodiments, when the external charger does not meet the detection conditions, the method may further include:

[0130] Step S105, acquiring a reference charging parameter of the external charger according to the second posture information;

[0131] Step S106, obtaining a first similarity between the reference charging parameter and the current charging parameter, and when the first similarity is not less than a preset similarity, updating the charging parameter of the external charger according to the reference charging parameter.

[0132] Therefore, when the external charger does not meet the detection conditions, the reference charging parameters can also be obtained based on the second posture information, and the charging parameters can be updated according to the reference charging parameters. Specifically, when the external charger does not meet the detection conditions, that is, when the matching degree between the two does not reach the preset threshold, the reference charging parameters can also be obtained based on the second posture information, which is used as a reference for the current charging parameters. A first similarity between the current charging parameters and the reference charging parameters is obtained, and the first similarity can be calculated by comparing the differences between the parameters to quantify the similarity between the current charging parameters and the reference charging parameters. If the first similarity is not less than the preset similarity threshold, that is, the similarity between the current charging parameters and the reference charging parameters is high enough, the current charging parameters are updated according to the reference charging parameters in the hope of optimizing the charging effect. It can be considered that the above parameter update adjustment is a fine-tuning of the current charging parameters.

[0133] On the one hand, fine-tuning of charging parameters can make the charging parameters closer to the optimal state without destroying the overall stability, thereby achieving more efficient energy transmission and charging effects. On the other hand, the fine-tuning mechanism can automatically adapt to different charging scenarios and patient postures according to actual conditions, providing a charging experience that better meets the needs.

[0134] In summary, when the external charger does not meet the detection conditions, the matching score does not reach or exceed the preset matching threshold. This is generally because the matching degree between the external charger and the pulse generator is not high due to the temporary position change of the external charger. In this case, the charging parameters are updated according to the first posture information obtained by the external charger, which is prone to misadjustment. In this case, the reference charging parameters are obtained based on the second posture information, and the charging parameters are fine-tuned according to the reference charging parameters, which has a high level of intelligence.

[0135] This application does not limit the method for obtaining the first similarity and the second similarity mentioned below. The method for obtaining the first similarity between the reference charging parameter and the current charging parameter may be to calculate the similarity of the parameters using a similarity calculation method (such as Euclidean distance, cosine similarity, etc.). The first similarity and the second similarity are, for example, 89%, 95% or 0.98, respectively.

[0136] See also Figure 6 , Figure 6 It is a flow chart of another charging control method of an external charger provided in an embodiment of the present application.

[0137] In some embodiments, the method may further include:

[0138] Step S107, when the charging parameters of the external charger need to be adjusted, the number of times the charging parameters are adjusted is counted to obtain a cumulative number;

[0139] Step S108, when the cumulative number is greater than the preset cumulative number, a prompt message is sent to the user device, and the cumulative number is cleared; the prompt message is used to indicate that the current charging parameters do not match the external charger and the pulse generator.

[0140] The user device is, for example, a doctor's programmable device, a patient's programmable device, a computer or a tablet, etc. The user of the user device may be a doctor, a patient's guardian, a community service worker or the patient himself.

[0141] Thus, the accumulated number of adjustments is compared with the preset accumulated number. If the accumulated number exceeds the preset number, it means that multiple charging parameter adjustments have occurred within a period of time. When the accumulated number exceeds the preset number, a prompt message is sent to the user device to remind the user that there may be a mismatch between the current charging parameters and the external charger and pulse generator. After sending the prompt message to the user, the accumulated number will be cleared to start the next stage of counting. By accumulating the number of adjustments and sending prompt messages, the user can be reminded that the current charging parameters may not match the external charger and pulse generator, attracting the user's attention and avoiding harm to the patient. On the other hand, the preset accumulated number can help prevent frequent charging parameter adjustments, thereby reducing the possibility of misoperation. The counting and prompt mechanism can help users better understand the adjustment of the charging parameters.

[0142] The preset cumulative number of times is, for example, 10 times, 100 times, or 150 times. The prompt message sent to the user device may be a voice message, a text message, or an image message, etc., which is not limited in this application. Taking a text message as an example, the prompt message may be a question reminder such as "The current charging parameter matching degree is not high, please temporarily stop charging".

[0143] See also Figure 7 , Figure 7 It is a schematic diagram of another flow chart for updating charging parameters provided in an embodiment of the present application.

[0144] In some embodiments, updating the charging parameters of the external charger according to the first posture information (ie, step S103) may include:

[0145] Step S401, inputting the first posture information into a parameter configuration model to obtain a plurality of recommended charging parameters corresponding to the external charger;

[0146] Step S402: obtaining a second similarity between each of the recommended charging parameters and the current charging parameters, and selecting the recommended charging parameter corresponding to the highest second similarity to update the charging parameter of the external charger.

[0147] Therefore, by calculating the similarity between different recommended parameters and the current parameters, the recommended parameters most similar to the current parameters are automatically selected to update the charging parameters. By selecting more similar recommended parameters to update the charging parameters, the current posture can be matched more accurately, thereby improving the energy transmission efficiency.

[0148] The training process of the parameter configuration model may include:

[0149] Acquire a training set, the training set comprising a plurality of training data, each of the training data comprising first posture information of a sample patient and corresponding charging parameter annotation data;

[0150] For each training data in the training set, perform the following processing:

[0151] Inputting the first posture information of the sample patient in the training data into a preset deep learning model to obtain corresponding prediction data of the charging parameters;

[0152] Based on the prediction data and the annotation data of the corresponding charging parameters, updating the model parameters of the deep learning model;

[0153] Detect whether the preset model training end condition is met; if so, use the trained deep learning model as the parameter configuration model; if not, continue to train the deep learning model using the next training data.

[0154] Therefore, by designing, establishing an appropriate amount of neuron computing nodes and a multi-layer operation hierarchy, and selecting appropriate input and output layers, a preset deep learning model can be obtained. Through the learning and tuning of the deep learning model, a functional relationship from input to output is established. Although the functional relationship between input and output cannot be found 100%, the actual correlation relationship can be approached as much as possible. The parameter configuration model obtained by training can obtain the corresponding charging parameters based on the first posture information. It has a wide range of applications, and the calculation results are highly accurate and reliable.

[0155] The embodiment of the present application can train a parameter configuration model, and can also use a pre-trained parameter configuration model. The present application does not limit the training process of the parameter configuration model, which can, for example, use the above-mentioned supervised learning training method, or can use a semi-supervised learning training method, or can use an unsupervised learning training method.

[0156] The present application does not limit the preset model training end conditions, which may be, for example, the number of training times reaches a preset number (the preset number of times may be, for example, 1 time, 3 times, 10 times, 100 times, 1000 times, 10000 times, etc.), or the training data in the training set has completed one or more trainings, or the total loss value obtained from this training is not greater than the preset loss value.

[0157] In a specific application scenario, an embodiment of the present application further provides a charging control method of an external charger, wherein the external charger is used to charge a pulse generator, and the method includes:

[0158] Acquiring first posture information of the patient through the external charger;

[0159] Acquiring second posture information of the patient through the pulse generator;

[0160] Acquire a matching score between the external charger and the pulse generator according to the first posture information and the second posture information;

[0161] Determining whether the external charger meets the detection conditions based on the matching score and a preset matching threshold;

[0162] When the external charger meets the detection condition, a judgment of the charging parameters of the external charger is performed to judge whether the charging parameters of the external charger need to be adjusted, wherein the charging parameters include one or more of a resonant voltage, a resonant frequency, a resonant matching capacitance, a coil position parameter, and a coil angle parameter;

[0163] When the charging parameters of the external charger need to be adjusted, the charging parameters of the external charger are updated according to the first posture information; and the number of times the charging parameters are adjusted is counted to obtain a cumulative number; when the cumulative number is greater than a preset cumulative number, a prompt message is sent to the user device, and the cumulative number is cleared; the prompt message is used to indicate that the current charging parameters do not match the external charger and the pulse generator;

[0164] When the external charger does not meet the detection conditions, obtain a reference charging parameter of the external charger according to the second posture information; obtain a first similarity between the reference charging parameter and the current charging parameter, and when the first similarity is not less than a preset similarity, input the first posture information into a parameter configuration model to obtain a plurality of recommended charging parameters corresponding to the external charger; obtain a second similarity between each of the recommended charging parameters and the current charging parameters, and select the recommended charging parameter corresponding to the highest second similarity to update the charging parameters of the external charger.

[0165] In a specific application scenario, patient C uses an implantable neurostimulator to treat depression and needs to charge the pulse generator of his neurostimulator through an external charger to maintain the treatment effect.

[0166] The external charger has a built-in accelerometer sensor that can detect the posture information of patient B. Through these sensors, the external charger obtains the first posture information of patient C during the charging process, including the pitch angle, etc. The pulse generator is also equipped with a sensor that can obtain the second posture information of patient C and synchronize it with the first posture information of the external charger.

[0167] The matching score of the first posture information and the second posture information is obtained based on the first posture information and the second posture information, and it is assumed that the matching score is 98%. The matching score is compared with a preset matching threshold (95%) to determine that the matching meets the detection condition.

[0168] The charging parameters are judged based on the first posture information, and the judgment result is that the coil angle parameter in the charging parameters needs to be adjusted from an angle of -10 degrees to an angle of -5 degrees.

[0169] At the same time, the number of times the charging parameters are adjusted is counted. If the cumulative number reaches the preset value (3 times), a reminder text message is sent to the mobile phone of the attending physician of patient C, and the cumulative number is reset to zero. The content of the reminder text message is "Patient C has made 340 charging parameter adjustments in the last 24 hours, please pay attention to the doctor."

[0170] In the next charging, the matching score of the first posture information and the second posture information is obtained, assuming that the matching score is 90%. By comparing the matching score with the preset matching threshold (95%), it is determined that the external charger does not meet the detection conditions, and the reference charging parameters are obtained according to the second posture information: resonant voltage 11V, resonant frequency 150kHz, resonant matching capacitance 100pF, coil position parameters remain unchanged, and coil angle parameters 0 degrees. The first similarity between the reference charging parameters and the current charging parameters is calculated to be 0.92, which is not less than the preset similarity (0.75), and the reference charging parameters are used as new charging parameters.

[0171] In the next charging, the first posture information is input into the parameter configuration model to obtain multiple recommended charging parameters:

[0172] Recommended charging parameters 1: resonant voltage 12V, resonant frequency 155kHz, resonant matching capacitance 105pF, coil position parameter 5 degrees, coil angle parameter 0 degrees;

[0173] Recommended charging parameters 2: resonant voltage 11V, resonant frequency 150kHz, resonant matching capacitance 100pF, coil position parameter 5 degrees, coil angle parameter 5 degrees.

[0174] The second similarity between each of the above recommended charging parameters and the current charging parameters is calculated, wherein the similarity between the recommended charging parameter 1 and the current charging parameter is 0.85, and the similarity between the recommended charging parameter 2 and the current charging parameter is 0.95, then the recommended charging parameter 2 is selected as the new charging parameter.
