In the following, one of the application fields (namely, implantable neurostimulator) of the embodiment of the present application will be briefly described first.

An implantable neurostimulator system (an implanted medical system) mainly includes a stimulator implanted in a patient (ie, an implanted neurostimulator) and a program-controlled device placed outside the patient's body. The existing neuromodulation technology mainly uses stereotaxic surgery to implant electrodes in specific structures (i.e., targets) in the body, and the stimulator implanted in the patient sends electrical pulses to the targets through the electrodes to regulate the corresponding neural structures and networks. Electrical activity and its function, thereby improving symptoms and relieving pain. Among them, the stimulator can be an implantable electrical nerve stimulation device, an implantable cardiac electrical stimulation system (also known as a cardiac pacemaker), an implantable drug infusion device (Implantable Drug Delivery System, referred to as IDDS) and a wire. Any one of the switching devices. Implantable electrical nerve stimulation devices are, for example, Deep Brain Stimulation (DBS), Implantable Cortical Nerve Stimulation (CNS), Implantable Spinal Cord Stimulation , referred to as SCS), implanted sacral nerve stimulation system (Sacral Nerve Stimulation, referred to as SNS), implanted vagus nerve stimulation system (Vagus Nerve Stimulation, referred to as VNS), etc.

The stimulator can include IPG, extension wires and electrode wires. IPG (implantable pulse generator, implantable pulse generator) is set in the patient's body, receives program-controlled instructions sent by the program-controlled device, and relies on sealed batteries and circuits to provide controllable pulses to tissues in the body. The electrical stimulation energy, through the implanted extension lead and electrode lead, delivers one or two controllable specific electrical stimulations to specific areas of tissues in the body. The extension lead is used in conjunction with the IPG as a transmission medium for the electrical stimulation signal, and transmits the electrical stimulation signal generated by the IPG to the electrode lead. Electrode leads deliver electrical stimulation to specific areas of tissue in the body through multiple electrode contacts. The stimulator is provided with one or more electrode wires on one side or both sides, and a plurality of electrode contacts are arranged on the electrode wires, and the electrode contacts can be arranged uniformly or non-uniformly in 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 (a total of 12 electrode contacts) in the circumferential direction of the electrode wire. Electrode contacts may include stimulation electrode contacts and/or collection electrode contacts. The electrode contacts can be in the shape of, for example, a sheet, a ring, or a dot.

In some possible implementations, the stimulated body tissue may be the patient's brain tissue, and the stimulated site may be a specific part of the brain tissue. When the patient's disease type is different, the stimulated site is generally different, the number of stimulation contacts used (single source or multi-source), one or more channels (single-channel or multi-channel) specific electrical stimulation signals The application and stimulus parameter data are also different. The embodiment of the present application does not limit the applicable disease types, which may be the applicable disease types for deep brain stimulation (DBS), spinal cord stimulation (SCS), pelvic stimulation, gastric stimulation, peripheral nerve stimulation, and functional electrical stimulation. Among the types of disorders that DBS can be used to treat or manage include, but are not limited to: spasticity disorders (e.g., epilepsy), pain, migraine, psychiatric disorders (e.g., major depressive disorder (MDD)), bipolar disorder, anxiety disorders, Post-traumatic stress disorder, hypodepression, obsessive-compulsive disorder (OCD), conduct disorder, mood disorder, memory disorder, mental status disorder, mobility disorder (eg, essential tremor or Parkinson's disease), Huntington's disease, Al Alzheimer's disease, drug addiction, autism, or other neurological or psychiatric conditions and impairments.

In the embodiment of the present application, when the program-controlled device and the stimulator establish a program-controlled connection, the program-controlled device can be used to adjust the stimulation parameters of the stimulator (different stimulation parameters correspond to different electrical stimulation signals), and the stimulator can also be used to sense the deep brain of the patient. The bioelectric activity of the stimulator can be used to collect the electrophysiological signal, and the stimulation parameters of the electrical stimulation signal of the stimulator can be adjusted continuously through the collected electrophysiological signal.

Stimulation parameters may include: frequency (for example, the number of electrical stimulation pulse signals per unit time 1s, the unit is Hz), pulse width (the duration of each pulse, the unit is μs), amplitude (generally expressed in voltage, that is, The intensity of each pulse, the unit is V), timing (for example, it can be continuous or triggered), stimulation mode (including one or more of current mode, voltage mode, timed stimulation mode and cycle stimulation mode), doctor's control upper limit One or more of upper and lower limits (range adjustable by doctors) and upper and lower limits of patient control (range adjustable by patients).

In a specific application scenario, various stimulation parameters of the stimulator can be adjusted in current mode or voltage mode.

The program-controlled device may be a doctor-programmed device (ie, a program-controlled device used by a doctor) or a patient-programmed device (ie, a program-controlled device used by a patient). The doctor's program-controlled device can be, for example, a tablet computer, a notebook computer, a desktop computer, a mobile phone and other smart terminal devices equipped with program-controlled software. The patient program-controlled device can be, for example, smart terminal devices such as tablet computers, notebook computers, desktop computers, and mobile phones equipped with program-controlled software, and the patient program-controlled device can also be other electronic devices with program-controlled functions (such as chargers with program-controlled functions, data collection device).

The embodiment of the present application does not limit the data interaction between the doctor's program-controlled device and the stimulator. When the doctor remotely programs, the doctor's program-controlled device can perform data interaction with the stimulator through the server and the patient's program-controlled device.

Among them, the doctor's program-controlled equipment can exchange data with the server through the 3G/4G/5G network, the server can exchange data with the host through the 3G/4G/5G network, and the host can exchange data with the slave through the Bluetooth protocol/WIFI protocol/USB protocol.

Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a charging control method for an external charger provided in an embodiment of the present application. An embodiment of the present application provides a charging control method of an external charger, the external charger is used to charge a first stimulator implanted in a first patient, and the frequency and resonant voltage of the external charger can vary with the external charger. The relative positions of the charger and the first stimulator vary.

Among them, the external charger can generate an alternating electric field, so that the induction coil in the stimulator implanted in the human tissue can sense the above-mentioned alternating electric field and obtain energy, thereby charging the battery in the stimulator; the charging habit of the user is Refers to the habitual wearing position of the external charger when the user is charging. In the prior art, after each charging process starts, the charging frequency and resonant voltage of the external charger will be adaptively adjusted to suit the charging habits of different users .

The method includes steps S101 to S103.

Step S101: Record the final parameter value of the charging parameters in the multiple charging process of the first stimulator charged by the external charger, the charging parameters include one of the frequency and the resonant voltage of the external charger or more.

Step S102: Based on the final parameter value of the charging parameter in the multiple charging process of the first stimulator charged by the external charger, determine the recommended parameter value of the charging parameter corresponding to the first stimulator.

Step S103: Control the external charger to charge the first stimulator with the recommended parameter value of the charging parameter corresponding to the first stimulator, so as to improve the charging efficiency of the first stimulator by the external charger. Charging efficiency.

Thus, the final parameter values of the charging parameters in the multiple charging process of charging the first stimulator are recorded, and the recommended parameter values are determined according to the recorded parameters, and then the external charger is controlled to use the charging parameters corresponding to the first stimulator. The recommended parameter value is the first stimulator charging, which realizes the automatic adjustment of the charging parameters, so that the charging efficiency of the user can reach the best state when charging.

In some possible manners, the step S101 may include: recording the final parameters of the charging parameters of the charging process with a charging efficiency greater than a preset charging efficiency in all charging processes in which the external charger charges the first stimulator value.

Among them, the charging efficiency can be expressed as a percentage. For example, if the charging power is 8W, and the theoretical maximum charging power is 10W, then the charging efficiency is 80%. In terms of power, for example, it can be fully charged in 20 minutes, and 5% can be charged per minute.

Thus, recording the final parameter value of the charging parameter in the charging process whose charging efficiency is greater than the preset charging efficiency avoids using the parameter value lower than the preset charging efficiency as the recommended parameter value, ensuring the charging efficiency of the finally determined recommended parameter value It is higher than the preset charging efficiency, which further ensures the charging efficiency when using the recommended parameter values for charging.

Referring to FIG. 2 , FIG. 2 is a schematic flow chart of recording final parameter values provided by an embodiment of the present application. In some possible manners, the step S101 may include steps S201-S202.

Step S201: Obtain the final parameter value of the charging parameters of the last N charging processes of the first stimulator charged by the external charger, where N is an integer greater than 1;

Wherein, N can be a smaller value, such as 5, then obtain the final parameter value of the charging parameters of the last 5 charging processes of the first stimulator charged by the external charger, or it can be a larger value, For example, it is 50. When the value of N is larger, the obtained final parameter value is more accurate.

Step S202: When the external charger charges the first stimulator, the difference between the maximum value and the minimum value of the final parameter values of each charging parameter in the latest N charging processes is not greater than the corresponding charging parameter When the preset value of the first stimulator is charged by the external charger, the final parameter value of the charging parameter of the last N charging processes of the first stimulator is recorded.

Wherein, the preset value corresponding to the charging parameter can be a fixed value, for example, when the charging parameter is the resonance voltage, the preset value corresponding to the charging parameter can be 5V, or it can be a floating value adjusted according to the user's initial usage habits , for example, when the user charges for the first time, the charging efficiency reaches the maximum efficiency, then the preset value corresponding to the charging parameter can be adjusted to a lower value, such as 1V, when the user charges for the first time, the charging efficiency If there is a large gap with the maximum efficiency, for example, only reaching 50% of the maximum efficiency, the preset value corresponding to the charging parameter can be adjusted to a higher value, such as 10V.

Thus, the final parameter value of the last N charging processes is obtained, and when the range of the final parameter value of each charging parameter is not greater than the preset value, the final parameter value of the charging parameter of the last N charging processes is recorded; it is the final parameter The value record is added with a full-range condition, which limits the distribution range of the final parameter value of the charging parameter, avoids the interference of individual values with large differences on the final result, and makes the recorded final parameter value closer to the real charging state. , ensuring the accuracy of the recommended parameter values.

Among them, the full distance refers to the difference between the maximum value and the minimum value among the final parameter values of each charging parameter. For example, when the charging parameter is the resonance voltage, the final parameter values of multiple charging parameters are 5V, 10V, and 8V respectively. And 7V, then its full range is 5V.

In some possible manners, the final parameter value of the charging parameter of each charging process may be obtained as follows: the parameter value of the charging parameter after the first preset time period from the start moment of each charging process is used as the parameter value of each charging process The final parameter value of the charging parameter of the charging process; or, the parameter value of the charging parameter that remains stable within the second preset time period of each charging process is used as the final parameter value of the charging parameter of each charging process, and the stable The range of variation of the charging parameter satisfying the parameter value of the charging parameter is not greater than the preset range corresponding to the charging parameter.

Wherein, the first preset duration or the second preset duration is, for example, 1 min, 5 min or 30 min. In some possible ways, different first preset durations or second preset durations can be set according to different types of first patients. Set the duration; the preset range can be preset as a fixed value, or different preset ranges can be set according to the type of the first patient. For example, when the charging parameter is the frequency of the charger, the preset range can be ±50Hz, or, if the first patient is a Parkinson's patient, the preset amplitude may be ±30Hz, and if the first patient is an obsessive-compulsive disorder patient, the preset amplitude may be ±70Hz.

Therefore, the parameter value of the charging parameter after the first preset time period from the start moment of each charging process is used as the final parameter value of the charging parameter of each charging process, and the efficiency of obtaining the final parameter value is high; The parameter value of the charging parameter that remains stable within the second preset time period in the charging process is used as the final parameter value of the charging parameter in each charging process, and the accuracy of the obtained final parameter value is relatively high.
