Description

Wireless charging authentication method, device, in-vitro charging system and storage medium

Technical Field

The present application relates to the technical field of medical systems, and in particular, to a wireless charging authentication method, a wireless charging authentication device, an in-vitro charging system, and a computer readable storage medium.

Background

With the continuous development of technology and the advancement of society, patients have an increasing desire to solve or delay patients and to improve the quality of life. To meet the above-mentioned needs of patients, various implantable medical systems are emerging that can provide various therapeutic means to serve patients.

Taking deep brain electrical stimulation (Deep brain stimulaiton, DBS) as an example, DBS is an invasive nerve regulation technology, stimulating electrodes are implanted in specific nerve structures in the human brain through a stereotactic operation method, and nerve stimulators are implanted in the human body to be connected with the electrodes, and weak electric pulses which can be regulated and controlled are emitted, so that the electrical activity and functions of brain nerve loops and networks are changed, and the aim of controlling and improving the symptoms of patients is achieved. Such delivery of weak electrical pulses requires that the implant be implanted in the patient to provide electrical energy thereto, i.e., that rechargeable battery implants (e.g., cardiac pacemakers, neurostimulators) be placed in the implant, often used to treat or assist a particular medical condition, and thus the patient may not possess sufficient performance as a regular person would possess. To alleviate the charging burden on the patient, related charging techniques typically ignore the authentication process of charging. However, this also presents potential risks and hazards to the patient's charging safety.

Based on this, the present application provides a wireless charging authentication method of an in vitro charging system, a wireless charging authentication device, an in vitro charging system, and a computer readable storage medium to solve the above-mentioned problems.

Disclosure of Invention

The application aims to provide a wireless charging authentication method, wireless charging authentication equipment, an in-vitro charging system and a computer readable storage medium of an in-vitro charging system, and an individualized charging strategy is obtained by conveniently authenticating the corresponding relation between a patient and an in-vitro charger and combining the authentication, so that the problem of burden brought to the patient by charging authentication is solved.

The application adopts the following technical scheme:

In a first aspect, the present application provides a wireless charging authentication method for an external charger to charge an implant of a user, the wireless charging authentication method comprising:

acquiring capacitance acquisition information by using the external charger, wherein the capacitance acquisition information comprises a plurality of capacitance values for indicating the position relationship between the external charger and the implant;

authenticating the corresponding relation between the user and the external charger according to the capacitance acquisition information and a preset capacitance data set of the external charger; the preset capacitance data set comprises a plurality of preset capacitance acquisition information;

When the authentication result of the corresponding relation indicates that the user passes authentication, a special charging strategy of the user is used as a current charging strategy of the external charger, so that the external charger charges the implant according to the special charging strategy, and the special charging strategy comprises charging frequency and/or charging voltage.

The beneficial effect of this technical scheme lies in: since fingerprint, iris, voiceprint, etc. modes generally require invasive operations such as pressing a fingerprint sensor, aligning an iris scanner, etc. during authentication, such invasive operations cause discomfort to a patient who needs to charge an implant, causing unnecessary pain to the patient. Compared with the mode of carrying out patient authentication by fingerprints, irises, voiceprints and the like, the technical scheme provided by the embodiment carries out patient authentication by the capacitance acquisition information, the capacitance acquisition information can reflect capacitance characteristics of implants and surrounding biological tissues in a patient, and as the capacitance characteristics have certain differences among individuals, compared with the biological characteristic recognition mode (such as fingerprints, irises and the like), the application of the capacitance acquisition information can better adapt to individual differences, and the accuracy and the safety of authentication are improved on the basis of biological characteristic diversity. On the other hand, the capacitive acquisition is used as a non-invasive biological recognition mode, a patient is not required to perform special operations such as fingerprint scanning or eyeball scanning, the use comfort and convenience of the patient can be improved, and the interference of the recognition process on the patient is reduced. On the other hand, the patient authentication and the charging process of the in-vitro charging equipment are mutually related, the use of the capacitance acquisition information and the selection of the charging strategy are tightly integrated, namely, the special charging strategy is triggered through the authentication of the capacitance acquisition information, so that the charging of the implant of the patient is more intelligent and personalized. On the other hand, the capacitor acquisition information can be acquired by the patient in the process of wearing the external charging equipment, the patient does not need additional operation or steps for authentication, the non-perception authentication mode improves the use convenience of the patient, potential interference in treatment of the implanted equipment on the patient is reduced, and discomfort in the charging process of the patient is reduced.

In summary, according to the technical scheme, the corresponding relation between the patient and the external charger is conveniently authenticated, and the personalized charging strategy is obtained in parallel, so that the safety and the efficiency of the wireless charging process of the patient are improved.

In some possible implementations, the wireless charging authentication method further includes:

When the authentication result of the corresponding relation indicates that the user fails authentication, acquiring a general charging strategy and taking the general charging strategy as a current charging strategy of the external charger, so that the external charger charges the implant according to the general charging strategy;

The general charging strategy comprises charging frequency and/or charging voltage, and the energy transmission efficiency corresponding to the general charging strategy is lower than the energy transmission efficiency corresponding to the special charging strategy.

The beneficial effect of this technical scheme lies in: in the event of authentication failure, the application of a generic charging strategy helps to ensure that the patient is still able to obtain basic charging services, improving the safety and reliability of the in vitro charger to the patient, ensuring that the patient is still able to maintain the normal function of the implant through charging (avoiding the implant from having electricity) even in the event of authentication failure. By distinguishing the special charging strategy from the general charging strategy, the special charging service can be provided when authentication is successful, and the general charging service is provided when authentication fails, so that the requirements of patients can be met under different conditions, and the method is humanized. When authentication fails, a general charging strategy is applied, namely, the technical scheme can obtain basic charging service without manual intervention (for example, by feeding back assistance to a manufacturer of an external charger) under the condition that a patient fails authentication, so that the threshold of authentication is reduced, unnecessary complicated steps are reduced, and the patient experience is improved.

In summary, according to the technical scheme, the special or general charging strategy is selectively applied according to the authentication result, so that the flexibility and the user friendliness of charging the implant are enhanced, and meanwhile, the patient is ensured to obtain safe and reliable charging service under various conditions.

In some possible implementations, the authenticating the correspondence between the user and the external charger according to the capacitance acquisition information and a preset capacitance data set of the external charger includes:

acquiring the capacitance similarity between the capacitance acquisition information and the preset capacitance data set according to the capacitance acquisition information;

when the capacitance similarity is not smaller than the preset similarity, the user passes authentication to be used as an authentication result; otherwise, the user is not authenticated as an authentication result.

The beneficial effect of this technical scheme lies in: the authentication of the patient is performed through the capacitance similarity, so that the accuracy of the corresponding relation between the patient and the external charger can be improved. Because the capacitance acquisition is real-time, the position change between the implant of the patient and the external charger can be responded in time, so that the authentication process is more real-time.

In some possible implementations, the means for obtaining the capacitance similarity includes:

Comparing the capacitance acquisition information with each preset capacitance acquisition information in the preset capacitance data set to obtain the similarity of the capacitance acquisition information and each preset capacitance acquisition information, and taking the highest similarity among a plurality of similarities corresponding to the capacitance acquisition information as the capacitance similarity.

The beneficial effect of this technical scheme lies in: the real-time capacitance acquisition information is acquired, and the capacitance acquisition information can be acquired through a capacitance formed between the excitation electrode and the receiving electrode, so that the capacitance relation between the patient and the external charger is reflected. The preset capacitance acquisition information is acquired and stored in advance, the preset capacitance data set comprises a plurality of preset capacitance acquisition information, and each preset capacitance acquisition information represents an expected capacitance state passing authentication. The comparison of the capacitance information collected in real time with each preset capacitance collection information in the preset capacitance data set may be performed in various manners, for example, based on a mathematical model or algorithm, so as to calculate the similarity between the two. In summary, the highest similarity is selected as the capacitance similarity, which is helpful to improve the accuracy of authentication. Because the capacitance value collection is real-time, the similarity calculation can be performed on the basis of real-time property, and the authentication state can be updated in time.

In some possible implementations, for each preset capacitance acquisition information, the preset capacitance data set further includes offset information, where the offset information is used to indicate an offset condition of the external charger corresponding to the preset capacitance acquisition information;

the taking the special charging strategy of the user as the current charging strategy of the external charger comprises the following steps:

S31, detecting the offset condition of the external charger according to the capacitance acquisition information and the preset capacitance data set of the user so as to obtain an offset result;

S32, when the offset result indicates that the offset between the external charger and the implant is lower than a preset offset threshold, executing a preset special charging strategy by using the external charging system; and when the offset result indicates that the offset between the external charger and the implant is not lower than a preset offset threshold, generating offset prompt information, wherein the offset prompt information is used for prompting the user that the position of the external charging system needs to be adjusted, and executing S31 after the capacitance acquisition information is changed.

The beneficial effect of this technical scheme lies in: whether the position of the external charger of the patient needs to be adjusted or not can be timely prompted through monitoring the offset, so that optimal alignment of the external charger and the implant can be guaranteed, and charging efficiency is improved. If the offset is small, a personalized special charging strategy can be implemented to provide the patient with a charging service that is more tailored to the patient's needs. Charging is only performed when the in-vitro charger corresponds well to the target site of the patient (when the offset is below a preset offset threshold), which can ensure that the charger is accurately aligned with the implant, improving the accuracy and efficiency of charging. By detecting the offset between the external charger and the target site of the patient before charging is performed, the erroneous charging caused by inaccurate position is effectively avoided, and the safety of the patient using the implant for a long time is important.

In summary, the present embodiment ensures the accuracy and individuation of the charging process by combining the patient authentication and the position detection process, so as to provide safer, more comfortable and more intelligent implant charging service for the patient.

In some possible implementations, when the offset result indicates that an offset between the external charger and the implant is not below a preset offset threshold, the method further comprises:

counting is started and the counted times are added by one;

Detecting whether the statistics times are greater than preset statistics times or not, when the increment of the statistics times in a preset time period is greater than the preset statistics times, carrying out zero clearing processing on the statistics times, and acquiring a general charging strategy and taking the general charging strategy as a current charging strategy of the external charger so that the external charger charges the implant according to the general charging strategy;

The beneficial effect of this technical scheme lies in: and starting statistics and adding one to the statistics when the offset between the in-vitro charger and the implant is detected to be not lower than a preset offset threshold value. The increase of the statistics times is based on statistics in a certain period, namely a preset time, and if the increase of the statistics times in the preset time exceeds the preset statistics times, the universal charging strategy is taken as the current charging strategy. This is because, when the offset is not brought to the proper range a plurality of times within the predetermined period of time, it is indicated that the patient's physical condition is poor and that the implant charge is urgently needed. In this case the implant of the patient is charged using a universal charging strategy.

Therefore, the offset times are continuously counted and monitored in real time within the preset time, the response can be quickly made when the position of the implant is offset, and the instantaneity of the charging strategy selection is improved. A more conservative charging scheme (general charging strategy) is adopted after the offset is detected, and the risk of false charging is reduced under the condition that the wireless charger and the implant deviate more.

In a second aspect, the present application also provides a wireless charging authentication device for an in vitro charger to charge an implant of a user, the wireless charging authentication device comprising a memory and at least one processor, the memory storing a computer program, the at least one processor being configured to implement the following steps when executing the computer program:

In some possible implementations, the at least one processor is configured to authenticate the correspondence between the user and the external charger based on the capacitance acquisition information and a preset capacitance dataset of the external charger when executing the computer program in the following manner:

In some possible implementations, the at least one processor is configured to obtain the capacitance similarity when executing the computer program by:

The at least one processor is configured to take the user's special charging policy as the current charging policy of the in vitro charger when executing the computer program in the following manner:

When the offset result indicates that the offset between the external charger and the implant is not lower than a preset offset threshold value, starting statistics and adding one to the statistics times;

the external charger is in communication connection with the wireless charging authentication device, and is used for acquiring a plurality of capacitance values used for indicating the position relationship between the external charger and the implant of the user in real time and charging the implant of the user according to the current charging strategy.

The beneficial effect of this technical scheme lies in: by collecting capacitance information of a patient in real time, the wireless charging authentication device implements authentication between a user and an external charger, and ensures that a special charging strategy is implemented only when the user and the external charger are matched, which is helpful for preventing activation of a wrong charging mode and improving charging safety

Detailed Description

The technical scheme of the present application will be described below with reference to the drawings and the specific embodiments of the present application, and it should be noted that, on the premise of no conflict, new embodiments may be formed by any combination of the embodiments or technical features described below.

In embodiments of the application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any implementation or design described as "exemplary" or "e.g." in the examples of this application should not be construed as preferred or advantageous over other implementations or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

In the following, a brief description will be given of one of the application fields (i.e., the implantable neural stimulation system) of the embodiments of the present application.

An implantable neurostimulation system (a medical system) mainly includes a stimulator implanted in a patient and a programmable device disposed outside the patient. The related nerve regulating technology is mainly to implant electrodes at specific parts (namely targets) of tissues of organisms through stereotactic surgery, and to send electric pulses to the targets through the electrodes by a stimulator implanted in a patient, so as to regulate the electric activities and functions of corresponding nerve structures and networks, thereby improving symptoms and relieving pains. The stimulator may be any one of an implantable nerve electrical stimulation device, an implantable cardiac electrical stimulation system (also called a cardiac pacemaker), an implantable drug infusion device (Implantable Drug DELIVERY SYSTEM, abbreviated as IDDS), and a lead switching device. Examples of the implantable nerve electrical stimulation device include a deep brain electrical stimulation system (Deep Brain Stimulation, abbreviated DBS), an implantable cortex stimulation system (Cortical Nerve Stimulation, abbreviated CNS), an implantable spinal cord electrical stimulation system (Spinal Cord Stimulation, abbreviated SCS), an implantable sacral nerve electrical stimulation system (SACRAL NERVE Stimulation, abbreviated SNS), an implantable vagal nerve electrical stimulation system (Vagus Nerve Stimulation, abbreviated VNS), and the like.

In some embodiments, the stimulator may include a pulse generator (Implantable Pulse Generator, IPG), an electrode lead, and an extension lead disposed between the pulse generator and the electrode lead through which data interaction of the pulse generator and the electrode lead is accomplished, the pulse generator disposed within the patient. In response to a programming instruction sent by the programming device, controllable electrical stimulation energy is provided to the internal tissue by means of the sealed battery and the circuit, and one or two controllable specific electrical stimulations are delivered to specific areas of the internal tissue through the implanted extension leads and electrode leads. The extension lead is matched with the pulse generator to be used as a transmission medium of the electric stimulation signal, and the electric stimulation signal generated by the pulse generator is transmitted to the electrode lead. The electrode leads deliver electrical stimulation to specific areas of tissue in the body through electrode contacts thereon. The stimulator is provided with one or more electrode leads on one side or two sides, and a plurality of electrode contacts are arranged on the electrode leads.

In other embodiments, the stimulator may include only the pulse generator and the electrode leads. The pulse generator can be embedded on the skull of the patient, the electrode lead is implanted in the skull of the patient, and the pulse generator is directly connected with the electrode lead without extending the lead.

The electrode lead may be a neural stimulation electrode that delivers electrical stimulation to a specific region of tissue in the body through a plurality of electrode contacts. The stimulator is provided with one or more electrode wires on one side or two sides, a plurality of electrode contacts are arranged on the electrode wires, and the electrode contacts can be uniformly arranged or non-uniformly arranged on the circumferential direction of the electrode wires. As an example, the electrode contacts may be arranged in an array of 4 rows and 3 columns (12 electrode contacts in total) in the circumferential direction of the electrode wire. The electrode contacts may include stimulation contacts and/or harvesting contacts. The electrode contact may take the shape of a sheet, ring, dot, or the like, for example.

In some possible ways, the stimulated in vivo tissue may be brain tissue of a patient and the stimulated site may be a specific site of brain tissue. When the type of disease in the patient is different, the location to be stimulated will generally be different, as will the number of stimulation contacts (single or multiple sources) used, the application of one or more (single or multiple channels) specific electrical stimulation signals, and the stimulation parameter data. It is believed that when the stimulus contacts used are multi-source, multi-path (multi-channel), a larger amount of data is generated than with single source, single path.

The embodiment of the application is not limited to the applicable disease types, and can be the disease types applicable to Deep Brain Stimulation (DBS), spinal Cord Stimulation (SCS), pelvic stimulation, gastric stimulation, peripheral nerve stimulation and functional electrical stimulation. Among the types of diseases that DBS may be used to treat or manage include, but are not limited to: spasticity (e.g., epilepsy), pain, migraine, psychotic disorders (e.g., major Depressive Disorder (MDD)), bipolar disorder, anxiety, post-traumatic stress disorder, 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 disorders and impairments.

In the embodiment of the application, when program control equipment and a stimulator are connected in a program control manner, the program control equipment can be utilized to send a communication instruction to the stimulator, the instruction information in the communication instruction is utilized to adjust the stimulation parameters of the stimulator (different electrical stimulation signals corresponding to different stimulation parameters) or acquire the state of the stimulator (such as electric quantity, model of the stimulator and the like), the stimulator can also be utilized to sense the bioelectrical activity of the deep brain of a patient to acquire an electrophysiological signal, and the acquired electrophysiological signal can be utilized to continuously adjust the stimulation parameters of the electrical stimulation signal of the stimulator.

The stimulation parameters may include: frequency (e.g., in Hz, the number of electrical stimulation pulse signals per unit time 1 s), pulse width (duration of each pulse in mus), amplitude (typically expressed in terms of voltage, i.e., intensity of each pulse in V), timing (e.g., continuous or triggered), stimulation mode (including one or more of current mode, voltage mode, timed stimulation mode, and cyclic stimulation mode), physician upper and lower limits (physician adjustable range), and patient upper and lower limits (patient autonomously adjustable range).

In one specific application scenario, the various stimulation parameters of the stimulator may be adjusted in either current mode or voltage mode.

The programming device may be a doctor programming device (i.e., a programming device used by a doctor) or a patient programming device (i.e., a programming device used by a patient or a patient's family). The doctor program control device may be, for example, an intelligent terminal device such as a tablet computer, a notebook computer, a desktop computer, or a mobile phone, which is equipped with program control software. The patient program control device can be, for example, an intelligent terminal device such as a tablet computer, a notebook computer, a desktop computer, a mobile phone and the like which are provided with program control software, and the patient program control device can also be other electronic devices with program control functions (for example, a charger with program control functions and a data acquisition device).

In the related art, user authentication may be implemented by means of a fingerprint, iris, voiceprint, etc., and only after authentication is passed, the user can use the related device or use the corresponding configuration of the device. However, the above-described user authentication method is mainly applicable in the consumer electronics field, and it is not considered from the point of view of the patient how to achieve wireless charging verification of the implant. Particularly for patients suffering from diseases requiring Deep Brain Stimulation (DBS), spinal Cord Stimulation (SCS), pelvic stimulation, gastric stimulation, peripheral nerve stimulation, functional electrical stimulation, etc., wireless charging verification schemes for their special cases are lacking.

Based on the above, the application provides a wireless charging authentication method, wireless charging authentication equipment, an in-vitro charging system and a computer readable storage medium of an in-vitro charging system, and the in-vitro charger is used for acquiring capacitance acquisition information, conveniently authenticating the corresponding relation between a patient and the in-vitro charger, and obtaining a personalized charging strategy in parallel, so that the charging safety is improved on the premise of not bringing operation burden to a user.

An in-vitro charging system will be described first, and a wireless charging authentication method, a wireless charging authentication apparatus, and the like for an in-vitro charger will be described later.

System embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an in vitro charging system according to an embodiment of the present application.

The embodiment of the application provides an in-vitro charging system which comprises an in-vitro charger and wireless charging authentication equipment.

The wireless charging authentication equipment is used for acquiring a current charging strategy; the external charger is in communication connection with the wireless charging authentication device, and is used for acquiring a plurality of capacitance values for indicating the position relationship between the external charger and the implant of the user in real time and charging the implant of the user according to the current charging strategy.

The specific embodiments of the wireless charging authentication device are consistent with the embodiments described in the device embodiments and the method embodiments, and the achieved technical effects, and are set forth below, and some of them are not described herein.

The implant according to the application is, for example, an implantable medical device such as an implantable pulse generator, and the battery sealed in the pulse generator can be charged by an external charging system according to a preset charging strategy.

An external charger is a device responsible for charging an implant implanted in a patient, which may employ wireless charging techniques to transfer electrical energy to the implant by way of an electromagnetic field to charge the implant. The in vitro charger may also collect capacitance acquisition information of the patient in real time before determining the charging strategy. And the external charger and the wireless charging authentication equipment are in communication connection so that the capacitance acquisition information is transmitted to the wireless charging authentication equipment. The wireless charging authentication equipment can process and analyze the received capacitance acquisition information, and then authenticate the corresponding relation between the implant and the user.

Therefore, the wireless charging authentication equipment performs authentication between the user and the external charger by collecting a plurality of capacitance values between the external charger and the implant of the user in real time, and charges according to the current charging strategy obtained after authentication (ensures that a special charging strategy is only implemented under the condition that the user and the external charger are matched), so that activation of an incorrect charging mode is prevented, and charging safety is improved.

In some embodiments, the in vitro charger comprises:

an excitation electrode for releasing an electrical signal to the implant;

The excitation electrode is used for releasing an electric signal to a target site (i.e. an implant) of a patient, wherein the electric signal can be an alternating current electric signal, and the frequency or the amplitude of the alternating current electric signal is not limited. When the excitation electrode releases the electrical signal, the electrical signal passes through the skin, human tissue and propagates to the surrounding receiving electrode. Because of the dielectric properties of skin and human tissue, electrical signals cause charge distribution and electric field formation during propagation, resulting in the formation of capacitance between the excitation electrode and the receiving electrode. It will be appreciated that in the above embodiments the human tissue acts as the dielectric of the capacitor, while the excitation electrode and the receiving electrode form the two plates of the capacitor to form a planar capacitor-like effect. At the same time, the implant may be considered as incorporating additional dielectric materials, the physical properties of the implant itself, the dielectric constant of the material, and interactions with surrounding tissue may have an effect on the capacitance value, thereby altering the capacitance value between the excitation electrode and the receiving electrode.

Meanwhile, since there is a difference in characteristics of human tissues of different users, characteristics are, for example, thickness of skin, density of tissue (fluid), thickness of skull, etc. The difference in characteristics affects the propagation of the electrical signal in the receiving electrode and the excitation electrode, and thus the capacitance value between the excitation electrode and each receiving electrode.

The information acquisition module can comprise an analog output unit and a signal amplification unit, wherein one end of the information acquisition module is connected with a power supply unit of the external charger, and the other end of the information acquisition module is connected with an excitation electrode and is used for outputting an (analog) electric signal amplified by the signal amplification unit by the excitation electrode. And the capacitive sensor can also comprise a plurality of groups of signal receiving units and an analog input module, wherein the signal receiving units are arranged between the analog input module and the receiving electrodes and are used for transmitting the electric signals received by the receiving electrodes to the analog input module so as to obtain capacitance acquisition information.

In a particular application, the stimulating electrode and the receiving electrode are both disposed on a lower surface of the external charger, which means that the external charger tends to be in intimate contact with the scalp during use. In this case, the loss of electrical signals before the excitation electrode and the receiving electrode is less.

In some embodiments, the wireless charging authentication device is integrated on the external charger. The wireless charging authentication device is integrated on the external charger, so that the integration and compactness of the medical system can be improved.

In some embodiments, the implant is a pulse generator implanted in the user's body, or a pulse generator implanted on the user's skull.

Referring to fig. 2, fig. 2 is a schematic illustration of the location of an external charger and implant provided by an embodiment of the present application.

In one particular application, an in vitro charger is provided for charging a pulse generator implanted on the skull of the user. The external charger comprises an excitation electrode and a plurality of receiving electrodes arranged around the excitation electrode. The implant includes a titanium shell, a battery within the titanium shell, and a coil for charging.

When the user places the external charger over the implant (in a state where the lower surface of the external charger and the scalp tend to be in intimate contact), the excitation electrode releases an electrical signal in the direction of the implant, which passes through the skin, the implant, and the tissue between the skin and the implant, causing a change in the charge distribution between the excitation electrode and each of the receiving electrodes during the propagation of the electrical signal, forming a capacitance between the excitation electrode and the receiving electrode. Referring to fig. 2, wherein broken lines connect the excitation electrode and each of the receiving electrodes, respectively, for illustrating a transmission path of the electric signal. Obviously, as the external charger moves, the capacitance value between each set of electrodes (the receiving electrode and the exciting electrode) will change. In addition, different users may have different capacitance values (between the receiving electrodes and the exciting electrodes, respectively) due to the differences in skin, human tissue and skull bone dimensions.

Method embodiment.

Referring to fig. 3, fig. 3 is a flow chart of a wireless charging authentication method provided by the embodiment of the present application, where the wireless charging authentication method is used for an external charger to charge an implant of a user, and a specific embodiment of the external charger is consistent with the embodiment described in the system embodiment and the achieved technical effect, and some of the details are not repeated.

The wireless charging authentication method comprises the following steps:

S101, acquiring capacitance acquisition information by using the external charger; the capacitance acquisition information includes a plurality of capacitance values for indicating a positional relationship of the external charger and the implant;

s102, authenticating the corresponding relation between the user and the external charger according to the capacitance acquisition information and a preset capacitance data set of the external charger; the preset capacitance data set comprises a plurality of preset capacitance acquisition information;

s103, when the authentication result of the corresponding relation indicates that the user passes authentication, taking a special charging strategy of the user as a current charging strategy of the external charger so that the external charger charges the implant according to the special charging strategy; the special charging strategy comprises a charging frequency and/or a charging voltage.

The above wireless charging authentication method may be run on an electronic device (i.e. a wireless charging authentication device mentioned below), the electronic device and a device (for use by a patient) for charging the implant (i.e. an extracorporeal charging device) may be independent of each other, and the electronic device may be integrated with the extracorporeal charging device. The user referred to in the present application may be a patient, or a human subject, treated with an implantable neurostimulation system, as will be described below by way of example.

Capacitance is formed between each receiving electrode and the exciting electrode in the external charging equipment, and capacitance values are acquired in real time to form capacitance acquisition information of a patient. The capacitance acquisition information is compared with a preset capacitance data set, wherein the preset capacitance data set can be a plurality of groups of capacitance values (namely, a plurality of preset capacitance acquisition information, each preset capacitance acquisition information can comprise a group of capacitance values) acquired in advance by using an external charger for a patient corresponding to the external charger, and each group of capacitance values comprises a capacitance value between each receiving electrode and each exciting electrode. The authentication process of the correspondence may be considered to ensure that the extracorporeal charging device used by the patient is matched with the extracorporeal charging device, and when the authentication result indicates that the patient passes the authentication, the special charging policy is the charging policy matched with the patient. The special charging strategy may include a charging frequency and/or charging voltage tailored to the patient to meet the specific needs of the patient's individual.

Thus, since fingerprint, iris, voiceprint, etc. methods generally require invasive operations such as pressing a fingerprint sensor, aligning an iris scanner, etc. during authentication, such invasive operations cause discomfort to a patient who needs to charge an implant, and cause unnecessary pain to the patient. Compared with the mode of carrying out patient authentication by fingerprints, irises, voiceprints and the like, the technical scheme provided by the embodiment carries out patient authentication by the capacitance acquisition information, the capacitance acquisition information can reflect capacitance characteristics of implants and surrounding biological tissues in a patient, and as the capacitance characteristics have certain differences among individuals, compared with the biological characteristic recognition mode (such as fingerprints, irises and the like), the application of the capacitance acquisition information can better adapt to individual differences, and the accuracy and the safety of authentication are improved on the basis of biological characteristic diversity.

On the other hand, the capacitive acquisition is used as a non-invasive biological recognition mode, a patient is not required to perform special operations such as fingerprint scanning or eyeball scanning, the use comfort and convenience of the patient can be improved, and the interference of the recognition process on the patient is reduced.

On the other hand, the patient authentication and the charging process of the in-vitro charging equipment are mutually related, the use of the capacitance acquisition information and the selection of the charging strategy are tightly integrated, namely, the special charging strategy is triggered through the authentication of the capacitance acquisition information, so that the charging of the implant of the patient is more intelligent and personalized.

On the other hand, the capacitor acquisition information can be acquired by the patient in the process of wearing the external charging equipment, the patient does not need additional operation or steps for authentication, the non-perception authentication mode improves the use convenience of the patient, potential interference in treatment of the implanted equipment on the patient is reduced, and discomfort in the charging process of the patient is reduced.

Wherein the wireless charging authentication device may be pre-stored on a memory of the wireless charging authentication device mentioned below to facilitate direct recall; or can be invoked from a cloud server through a wireless charging authentication device.

In some embodiments, the wireless charging authentication method further comprises:

and when the authentication result of the corresponding relation indicates that the patient fails authentication, controlling the external charger not to charge the implant. In this case, the authentication result of the correspondence relationship is used to strictly control the use range of the external charger, and it can be understood that only the owner of the external charger can use it for charging.

Referring to fig. 4, fig. 4 is a flowchart of another wireless charging authentication method according to an embodiment of the present application.

S104, when the authentication result of the corresponding relation indicates that the user does not pass authentication, acquiring a general charging strategy and taking the general charging strategy as a current charging strategy of the external charger, so that the external charger charges the implant according to the general charging strategy;

In a specific application, the charging frequency of the general charging strategy is lower than the charging frequency of the special charging strategy, and/or the charging voltage of the general charging strategy is lower than the charging voltage of the special charging strategy.

After the patient performs the capacitor acquisition information authentication, whether the authentication is successful or not is judged according to the comparison result. If the authentication is successful, a special charging strategy is applied to the charging process of the extracorporeal charging device to the patient. Instead, a generic charging strategy (which may be understood to include a generic charging frequency and charging voltage) is obtained to ensure that patients who are not authenticated are still able to receive basic charging services. The charging frequency and/or voltage of the universal charging strategy, while lower, is still sufficient to provide the necessary energy to maintain the charging of the implant.

Therefore, in the case of authentication failure, the application of the universal charging strategy helps to ensure that the patient still can obtain basic charging services, improves the safety and reliability of the external charger to the patient, and ensures that the patient can still maintain the normal function of the implant through charging even if authentication fails (the implant can be prevented from being powered off). By distinguishing the special charging strategy from the general charging strategy, the special charging service can be provided when authentication is successful, and the general charging service is provided when authentication fails, so that the requirements of patients can be met under different conditions, and the method is humanized. When authentication fails, a general charging strategy is applied, namely, the technical scheme can obtain basic charging service without manual intervention (for example, by feeding back assistance to a manufacturer of an external charger) under the condition that a patient fails authentication, so that the threshold of authentication is reduced, unnecessary complicated steps are reduced, and the patient experience is improved.

The application does not limit the charging frequency and the voltage of the general charging strategy and the special charging strategy, as long as the energy transmission corresponding to the general charging strategy is lower than that of the special charging strategy. Illustrating:

The charging frequency of the general charging strategy is 120kHz, the voltage is 3V, and the charging frequency of the special charging strategy is 150kHz, and the voltage is 4.5V; or alternatively

The charging frequency of the general charging strategy is 80kHz, the voltage is 4V, and the charging frequency of the special charging strategy is 150kHz, and the voltage is 4.5V; or alternatively

The charging frequency of the general charging strategy is 150kHz, the voltage is 2V, and the charging frequency of the special charging strategy is 220kHz, and the voltage is 2V; or alternatively

The charging frequency of the general charging strategy is 100kHz, the voltage is 3V, and the charging frequency of the special charging strategy is 100kHz, and the voltage is 4.5V.

Referring to fig. 5, fig. 5 is a schematic flow chart of taking a special charging strategy as a current charging strategy according to an embodiment of the present application.

In some embodiments, for each preset capacitance acquisition information, the preset capacitance data set further includes offset information, where the offset information is used to indicate an offset condition of the external charger corresponding to the preset capacitance acquisition information;

The taking the special charging strategy of the user as the current charging strategy of the external charger (S103) comprises:

S201, detecting the offset condition of the external charger according to the capacitance acquisition information and a preset capacitance data set of the user so as to obtain an offset result;

S202, when the offset result indicates that the offset between the external charger and the implant is lower than a preset offset threshold, executing a preset special charging strategy by using the external charging system;

And S203, when the offset result indicates that the offset between the external charger and the implant is not lower than a preset offset threshold, generating offset prompt information, wherein the offset prompt information is used for prompting the user that the position of the external charging system needs to be adjusted, and executing S201 after the capacitance acquisition information is changed.

After the authentication is successful, determining whether to execute a special charging strategy according to the capacitance acquisition information and the offset information in the preset capacitance data set, and prompting the position adjustment of the external charger when necessary. Specifically, when the patient passes the authentication, the capacitance value in the capacitance acquisition information is compared with the data in the preset capacitance data set, and an offset result of the in-vitro charger is obtained. Specifically, if the offset is below a preset offset threshold, a preset special charging strategy is performed with the in vitro charger. If the offset is not lower than the preset offset threshold, offset prompt information is generated, and the offset prompt information is used for prompting that the position of the external charger of the patient needs to be adjusted. The prompting modes can be voice prompting, text prompting and the like, for example, prompting voice is played through a loudspeaker of the external charger, so that a patient is reminded of further adjustment when the position offset of the external charger is too large; or pushing the offset prompt information to mobile terminals such as mobile phones, tablets and the like of the patients to remind the users. After the capacitance acquisition information is changed, the position of the external charger can be considered to be adjusted by the patient, the offset result can be acquired again without the need of carrying out authentication on the corresponding relation between the user and the external charger again, and the efficiency is higher. It can be understood that, as long as the patient passes the authentication with the external charger, the charging is only performed when the external charger corresponds to the target part of the patient (i.e. the offset between the external charger and the target part of the patient is not lower than the preset offset threshold), and the charging policy must be a special charging policy which is matched with the patient after the authentication.

Therefore, whether the position of the external charger of the patient needs to be adjusted or not can be timely prompted by monitoring the offset, the optimal alignment of the external charger and the implant can be guaranteed, and the charging efficiency is improved. If the offset is small, a personalized special charging strategy can be implemented to provide the patient with a charging service that is more tailored to the patient's needs. Charging is only performed when the in-vitro charger corresponds well to the target site of the patient (when the offset is below a preset offset threshold), which can ensure that the charger is accurately aligned with the implant, improving the accuracy and efficiency of charging. By detecting the offset between the external charger and the target site of the patient before charging is performed, the erroneous charging caused by inaccurate position is effectively avoided, and the safety of the patient using the implant for a long time is important.

In some embodiments, the authenticating the correspondence between the user and the external charger according to the capacitance acquisition information and a preset capacitance data set of the external charger includes:

The preset capacitance data set may be considered to contain an expected range of capacitances between the authenticated patient and the external charger as a reference standard for authentication. The (capacitance) similarity represents the similarity degree of actually collected capacitance data and preset data, and is an index reflecting the authentication matching degree. And calculating the capacitance similarity by comparing the capacitance acquisition information acquired in real time with data in a preset capacitance data set. And if the capacitance similarity is not smaller than the preset similarity threshold, the patient passes the authentication. In contrast, the patient is considered not authenticated.

Therefore, the accuracy of the corresponding relation between the patient and the external charger can be improved by authenticating the patient through the capacitance similarity. Because the capacitance acquisition is real-time, the position change between the implant of the patient and the external charger can be responded in time, so that the authentication process is more real-time.

In a specific application, the collected capacitance information and each preset capacitance collected information in the preset capacitance data set may be respectively input into a similarity model, so as to obtain a plurality of similarities between the collected capacitance information and each preset capacitance collected information. The application is not limited to the training process of the similarity model, and for example, a training mode of supervised learning, a training mode of semi-supervised learning or a training mode of unsupervised learning can be adopted.

As an example, the training process of the similarity model includes:

acquiring a training set, wherein the training set comprises a plurality of training data, and each training data comprises a first sample object, a second sample object and similarity of the first sample object and the second sample object; wherein the first sample object and the second sample object each comprise a set of capacitance values;

For each training data in the training set, performing the following processing: inputting a first sample object and a second sample object in the training data into a preset similarity model to be trained so as to obtain the predicted similarity of the first sample object and the second sample object;

updating model parameters of the similarity model to be trained based on the predicted similarity of the first sample object and the second sample object;

detecting whether a preset training ending condition is met; if yes, taking the trained similarity model to be trained as the similarity model; if not, continuing to train the similarity model to be trained by using the next training data.

In some embodiments, the means for obtaining the capacitive similarity comprises:

The real-time capacitance acquisition information is acquired, and the capacitance acquisition information can be acquired through a capacitance formed between the excitation electrode and the receiving electrode, so that the capacitance relation between the patient and the external charger is reflected. The preset capacitance acquisition information is acquired and stored in advance, the preset capacitance data set comprises a plurality of preset capacitance acquisition information, and each preset capacitance acquisition information represents an expected capacitance state passing authentication. The comparison of the capacitance information collected in real time with each preset capacitance collection information in the preset capacitance data set may be performed in various manners, for example, based on a mathematical model or algorithm, so as to calculate the similarity between the two.

Therefore, the highest similarity is selected as the capacitance similarity, and the accuracy of authentication is improved. Because the capacitance value collection is real-time, the similarity calculation can be performed on the basis of real-time property, and the authentication state can be updated in time.

As one example, the capacitance acquisition information includes [ C1], C1 representing a plurality of actually acquired capacitance values; the preset capacitance data set comprises [ { C1', offset1}, { C2', offset2}, { C3', offset3}, wherein C1', C2', C3' respectively represent capacitance values corresponding to preset capacitance acquisition information, and Offset1, offset2 and Offset3 are used for indicating Offset conditions corresponding to each preset capacitance acquisition information. For example, if the degree of similarity between C1 and C2' is 98% and highest, 98% is taken as the capacitance degree of similarity. Since the 98% similarity is greater than the preset similarity of 90%, the authentication is considered to be passed.

In some embodiments, when the offset result indicates that an offset between the external charger and the implant is not below a preset offset threshold, the method further comprises:

counting is started and the counted times are added by one;

The application is not limited to the selection of the preset statistics, for example, 5 times, 10 times, 13 times, 15 times, 18 times, etc.

The present application is not limited to the selection of the preset time period, and is, for example, 5 seconds, 10 seconds, 15 seconds, 1 minute, 10 minutes, etc.

And starting statistics and adding one to the statistics when the offset between the in-vitro charger and the implant is detected to be not lower than a preset offset threshold value. The increase of the statistics times is based on statistics in a certain period, namely a preset time, and if the increase of the statistics times in the preset time exceeds the preset statistics times, the universal charging strategy is taken as the current charging strategy. This is because, when the offset is not brought to the proper range a plurality of times within the predetermined period of time, it is indicated that the patient's physical condition is poor and that the implant charge is urgently needed. In this case the implant of the patient is charged using a universal charging strategy.

In a specific application scenario, the embodiment of the application further provides a wireless charging authentication method, which comprises the following steps:

Acquiring the capacitance similarity between the capacitance acquisition information and the preset capacitance data set according to the capacitance acquisition information; the preset capacitance data set comprises a plurality of preset capacitance acquisition information;

When the capacitance similarity is not smaller than the preset similarity, the user passes authentication to be used as an authentication result; otherwise, taking the fact that the user fails to pass the authentication as an authentication result;

when the authentication result of the correspondence indicates that the user passes authentication:

S201, detecting the offset condition of the external charger according to the capacitance acquisition information and a preset capacitance data set of the user so as to obtain an offset result; such that the external charger charges the implant according to the particular charging strategy, the particular charging strategy comprising a charging frequency and/or a charging voltage;

S202, when the offset result indicates that the offset between the external charger and the implant is lower than a preset offset threshold, executing a preset special charging strategy by using the external charging system; and when the offset result indicates that the offset between the external charger and the implant is not lower than a preset offset threshold, generating offset prompt information, wherein the offset prompt information is used for prompting the user that the position of the external charging system needs to be adjusted, and executing S201 after the capacitance acquisition information is changed.

Detecting whether the statistics times are greater than preset statistics times or not, when the increment of the statistics times in preset time is greater than the preset statistics times, carrying out zero clearing processing on the statistics times, and acquiring a general charging strategy and taking the general charging strategy as a current charging strategy of the external charger so that the external charger charges the implant according to the general charging strategy.

And when the authentication result of the corresponding relation indicates that the user fails authentication, acquiring a general charging strategy and taking the general charging strategy as the current charging strategy of the external charger, so that the external charger charges the implant according to the general charging strategy.

The method for obtaining the capacitance similarity comprises the following steps: comparing the capacitance acquisition information with each preset capacitance acquisition information in the preset capacitance data set to obtain the similarity of the capacitance acquisition information and each preset capacitance acquisition information, and taking the highest similarity among a plurality of similarities corresponding to the capacitance acquisition information as the capacitance similarity.

The method comprises the steps of acquiring information for each preset capacitor, wherein the preset capacitor data set further comprises offset information, and the offset information is used for indicating the offset condition of the external charger corresponding to the preset capacitor acquisition information.
