Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0056] Embodiment 1

[0057] Figure 1 A wireless control method for a sacral nerve stimulator according to the present invention is provided, which includes the following steps:

[0058] Obtain the physiological signals of the sacral nerve region of the target user, and perform feature extraction on the physiological signals of the sacral nerve region to generate an initial set of stimulation parameters;

[0059] Dynamically match the initial set of stimulation parameters with a preset physiological adaptation model to generate a target set of stimulation parameters;

[0060] Send the target set of stimulation parameters to the control module of the sacral nerve stimulator through a wireless communication protocol to generate an executable stimulation instruction;

[0061] Execute the stimulation instruction, and continuously monitor the physiological feedback signals of the target user. Dynamically adjust the stimulation parameters according to the deviation degree between the feedback signals and the target stimulation parameters to generate an optimized set of stimulation parameters;

[0062] Synchronize the optimized set of stimulation parameters and historical stimulation data to the cloud database for cross-device data synchronization and mode verification;

[0063] Execute the final control instruction set according to the safety verification result of the sacral nerve stimulator.

[0064] Specifically, obtaining the physiological signals of the sacral nerve region of the target user and performing feature extraction on the physiological signals of the sacral nerve region to generate an initial set of stimulation parameters includes:

[0065] The myoelectric signals, pressure distribution signals and temperature signals of the sacral nerve region are collected through a multimodal sensor array. Specifically, a sensor array is formed by integrating multiple types of sensors to simultaneously collect different types of physiological signals from the sacral nerve region. The myoelectric signals use an electrode array attached to the skin surface to capture the electrical signals generated by neuromuscular activity. The pressure distribution signals use distributed pressure sensors to detect local pressure changes, such as detecting the pressure distribution on a cushion or mattress. The temperature signals use a micro temperature sensor to measure the regional temperature, paying attention to whether there is temperature abnormality or local inflammation.

[0066] The electromyographic signal is subjected to frequency domain filtering and noise suppression processing to extract the first characteristic waveform set; specifically, the collected electromyographic signal is usually mixed with power frequency interference and noise, and needs to be filtered in the frequency domain to obtain a set of clear electromyographic signal waveform data, which is called the first characteristic waveform set, reflecting the amplitude, frequency and other characteristics of muscle activity;

[0067] The pressure distribution signal is spatially modeled to generate a pressure gradient feature set; specifically, the pressure sensor array can provide pressure distribution data at different locations in the sacral nerve region. By mapping the readings of each pressure sensor to spatial coordinates, a pressure distribution model for the region can be constructed; spatial distribution modeling usually requires: recording the spatial position of the sensor (such as two-dimensional coordinates); recording the pressure value at the corresponding position; obtaining a continuous pressure distribution through interpolation or fitting methods (such as two-dimensional Gaussian fitting, Kriging interpolation, etc.); based on the distribution, the pressure gradient can be calculated, that is, the rate of change of pressure in a certain direction in space, and then the maximum gradient direction, gradient amplitude and other features can be obtained, thereby forming a pressure gradient feature set;

[0068] The temperature signal is segmented by threshold value to extract the feature set of abnormal temperature area; specifically, the temperature signal of the sacral nerve area can reflect physiological or pathological factors such as blood circulation status and inflammatory response; exemplary, threshold setting: if the normal body surface temperature is 36℃~37℃, the upper limit of 37.5℃ is set as the abnormal judgment standard; segmentation process: the temperature image or data is binarized, and the area with a temperature exceeding 37.5℃ is marked as abnormal; result: a feature set of abnormal temperature area is generated, which contains information such as the location, area and temperature value of the abnormal area;

[0069] The first characteristic waveform set, the pressure gradient characteristic set and the temperature abnormality area characteristic set are fused to generate an initial stimulation parameter set.

[0070] Specifically, the initial stimulation parameter set is dynamically matched with the preset physiological adaptation model to generate a target stimulation parameter set, including:

[0071] According to the amplitude characteristics of the electromyographic signals in the first characteristic waveform set, the preset stimulation intensity adjustment rules are matched to generate a first candidate parameter set; specifically, the amplitude information of the electromyographic signals is extracted from the first characteristic waveform set, and the appropriate stimulation intensity is determined using the preset stimulation intensity adjustment rules; if it is detected that the user's electromyographic activity is weak, a higher stimulation intensity may be required to induce the target neural response; if the user's electromyographic activity is too strong, it may mean that the stimulation intensity needs to be reduced to avoid over-stimulation; the generated stimulation intensity parameter set is called the first candidate parameter set;

[0072] According to the maximum pressure distribution area in the pressure gradient feature set, the preset stimulation frequency adjustment rules are matched to generate the second candidate parameter set; specifically, the area with the highest pressure or the most dramatic change is found from the pressure gradient feature set, and the stimulation frequency is determined according to the characteristics of the area; when the pressure is too high somewhere in the sacral nerve area, it may cause local ischemia or compression, and a specific frequency of nerve stimulation is required to improve blood circulation or relieve compression; the preset stimulation frequency adjustment rules are usually empirical or experimental rules; the generated stimulation frequency parameter set is called the second candidate parameter set;

[0073] According to the dynamic change trend of the temperature abnormality area feature set, the preset stimulation duration adjustment rule is matched to generate a third candidate parameter set; specifically, the temperature change trend in the temperature abnormality area feature set is analyzed to determine whether the temperature abnormality area is expanding or contracting, so as to adjust the stimulation duration; if the temperature abnormality area gradually expands, the stimulation duration may need to be extended to achieve better treatment; the generated stimulation duration parameter set is called the third candidate parameter set;

[0074] The first candidate parameter set, the second candidate parameter set and the third candidate parameter set are weightedly fused to generate a target stimulation parameter set.

[0075] Specifically, the target stimulation parameter set is sent to the control module of the sacral nerve stimulator through the wireless communication protocol to generate an executable stimulation instruction, including:

[0076] A low-power Bluetooth protocol is used to establish an encrypted communication link between the sacral nerve stimulator and the control terminal; specifically, low-power Bluetooth technology is used to establish a wireless communication connection between the sacral nerve stimulator and the control terminal, and encryption measures are used to ensure the security of data transmission; for example, the control terminal and the stimulator exchange keys during the pairing process and establish an AES encrypted link to ensure that parameter transmission is not stolen or tampered with;

[0077] The target stimulus parameter set is divided into multiple data packets, and a dynamic check code is added to each data packet. Specifically, to ensure the reliability of large - data - volume transmission, the target parameter set is split into multiple smaller data packets, and at the same time, a dynamically generated check code (such as CRC code) is attached to each data packet to detect transmission errors. Exemplarily, assuming the size of the target parameter set is 512 bytes, it can be divided into 8 data packets of 64 bytes each, and a CRC - 16 check code is calculated for each packet to facilitate the receiving end to verify the integrity of each packet.

[0078] The data packets are encapsulated according to a preset private communication protocol and sent to the control module through a multi - channel redundancy transmission mechanism. Specifically, the data packets are encapsulated according to the preset private communication protocol (i.e., adding information such as headers, tails, sequence numbers, etc.), and multi - channel redundancy transmission is adopted, that is, the same data is sent through multiple wireless channels simultaneously to improve the anti - interference ability. Exemplarily, if the device supports channels A, B, and C, the same data packet may be transmitted on three channels simultaneously, and the receiving end merges the data according to the channel conditions.

[0079] At the control module, the received data packets are subjected to check - code verification and integrity recombination to generate executable stimulus instructions. Specifically, at the control module of the sacral nerve stimulator, the received data packets are first subjected to error detection through the attached check code. After confirming that the data is correct, all data packets are recombined into a complete parameter set according to the sequence, and then specific stimulus instructions are generated. Exemplarily, if the check of a certain data packet fails, the system will request re - transmission to ensure that the finally combined parameter set is accurate and error - free, and then converted into control instructions that the device can directly execute.

[0080] Specifically, execute the stimulus instructions, monitor the physiological feedback signals of the target user in real - time, and dynamically adjust the stimulus parameters according to the deviation degree between the feedback signals and the target stimulus parameters to generate an optimized stimulus parameter set, including:

[0081] According to the electromyogram response delay value in the physiological feedback signal, calculate the deviation coefficient between the current stimulus amplitude and the target amplitude. Specifically, let the target response delay be T tar , the actual response delay be T act , then the deviation coefficient is δ represents the deviation coefficient;

[0082] If the deviation coefficient exceeds the preset threshold, generate the first optimized parameter based on the amplitude adjustment strategy in the historical optimization record. Specifically, when the calculated deviation coefficient exceeds the set threshold, refer to the amplitude adjustment strategy recorded in the past optimization process to correct the current stimulus amplitude.

[0083] Match the preset frequency adaptive algorithm to generate the second optimization parameter according to the pressure response fluctuation frequency in the physiological feedback signal; specifically, use the pressure response fluctuation frequency recorded in the feedback signal to match the preset frequency adaptive algorithm and adjust the stimulation frequency.

[0084] Perform priority sorting on the first optimization parameter and the second optimization parameter to generate an optimized stimulation parameter set; specifically, sort and combine the first optimization parameter (amplitude adjustment result) and the second optimization parameter (frequency adjustment result) according to the preset priority to generate a comprehensive optimized parameter set.

[0085] Specifically, synchronize the optimized stimulation parameter set and the historical stimulation data to the cloud database for cross-device data synchronization and mode verification, including:

[0086] Extract the historical stimulation pattern data set matching the current user from the cloud database; specifically, retrieve the data related to the current user's identity and historical treatment records from the cloud database to form a historical stimulation pattern data set.

[0087] Perform timestamp alignment and abnormal pattern filtering on the historical stimulation pattern data set to generate a verification reference data set; specifically, process the extracted historical data to unify the time scale (timestamp alignment) and remove abnormal data caused by reasons such as abnormal acquisition and device failures; if a sudden change (such as a sudden peak or trough) occurs in a certain record, it will be determined as abnormal and excluded; the processed clean data set is used as the reference data set.

[0088] Obtain the electromagnetic interference intensity and device connection stability parameters in the current environment to generate an environment adaptation factor set; specifically, collect the current environment parameters in real time, such as electromagnetic interference (EMI) intensity, device connection stability, etc., and generate an environment adaptation factor set for correcting the parameter synchronization and verification process.

[0089] Perform cross-device data synchronization and mode verification on the optimized stimulation parameter set according to the verification reference data set and the environment adaptation factor set to generate a final control instruction set; specifically, combine the verification reference data set and the environment adaptation factor to perform cross-verification on the current optimized stimulation parameter set to ensure its applicability on different devices (or in different working environments), and finally generate a verified final control instruction set.

[0090] Specifically, execute the final control instruction set according to the safety verification result of the sacral nerve stimulator, including:

[0091] Before the control instruction is executed, the operator's identity is verified through a biometric recognition module. Specifically, to prevent unauthorized operations, biometric recognition technology (such as fingerprint, face recognition, or iris scanning) is used to confirm the operator's identity before the control instruction is executed. The operator uses the fingerprint recognition module on the control terminal for identity verification, and can only proceed to the next step after successful verification.

[0092] If the identity verification is successful, a dynamic encryption key is generated based on the device unique identification code and the user identity code. Specifically, after successful verification, a dynamic encryption key is generated by combining the device's unique identification code (UID) and the user identity code, which is used to encrypt the control instruction set to prevent interception or tampering during transmission.

[0093] The final control instruction set is encrypted with the dynamic encryption key, and key matching decryption is performed at the stimulator end. Specifically, the final control instruction set is encrypted with the above dynamic key before being sent, and the stimulator end uses the same key for matching decryption after receiving it to ensure the security of data during transmission.

[0094] If the decryption is successful and the permission level meets the preset conditions, the execution of the final control instruction set is allowed. Specifically, successful decryption indicates that the data has not been tampered with, and the operator's identity and device pairing status are correct. The permission level means that not only the identity needs to be verified, but also it is necessary to determine whether the operator has sufficient permissions (such as the difference between doctor permissions and ordinary user permissions). Only when multiple verifications are passed will the stimulator perform the actual electrical stimulation action.
