[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In order to solve the technical problems in the existing technology that the eye massager has a relatively single function, cannot dynamically adjust the massage parameters according to the patient's eye condition, and cannot meet the needs of multiple usage scenarios at the same time, please refer to Figure 1-Figure 3 , this embodiment provides the following technical solutions: A vibration massage intelligently controlled eye care device comprises: an eye massager 1, both ends of the eye massager 1 are connected with straps 2 for fixing the eye massager 1, the straps 2 include but are not limited to: an elastic band with a certain width; a physical button 3 and an indicator light 4 are provided at one end of the outer side of the eye massager 1, the physical button 3 is used to turn on or off the eye massager 1, and is also used to select a massage mode, such as: cooling or heating, single-eye massage or double-eye massage; the indicator light 4 is used to display the use status of the eye massager 1, such as: blue represents that the eye massager 1 is implementing the cooling mode, and red light represents that the eye massager 1 is implementing the heating mode; and the two sides of the indicator light 4 are marked with "Z" and "Y", representing the left eye and the right eye respectively, if the light of the indicator light 4 marked with "Z" is turned on, it means that the left eye massage function is turned on, and vice versa; two groups of massage care units A are symmetrically arranged on the inner side of the eye massager 1, and a central processor B for controlling the massage care units A is provided inside the eye massager 1.

[0023] Massage care unit A includes: massage module and functional module.

[0024] The massage module is configured to simulate professional massage techniques based on a linear resonant motor array to perform Chinese medicine acupoint massage, relax the muscles around the eyes, and relieve eye fatigue.

[0025] The functional module is configured to provide heating and cooling functions based on semiconductor Peltier elements. Heating is used to promote blood circulation in the eyes, and cooling is used for cold compresses after surgery, thereby providing multiple massage modes to meet the needs of different usage scenarios.

[0026] The central processing unit B includes: a monitoring module, a control module, a selection module, an integration module, a storage module, an analysis module and a calling module.

[0027] The monitoring module is configured to consist of a micro intraocular pressure sensor, a temperature sensor and an electromyography sensor, which is installed on the inner side of the massage care unit A and in contact with the eye; the micro intraocular pressure sensor is used to monitor intraocular pressure data in real time; the temperature sensor is used to monitor the temperature data of the eye in real time, and the temperature sensor uses a thermistor; the electromyography sensor is used to monitor the electromyography activity data of the muscles around the eye in real time.

[0028] The control module is configured to use a microcontroller to dynamically adjust the vibration frequency and intensity of the massage module through a PID algorithm based on monitoring data and postoperative needs; the control module includes: The sample acquisition module is configured to acquire historical intraocular pressure data, temperature data, and electrical activity data of multiple patients and pre-process the data as data samples.

[0029] The threshold setting module is configured to preset the threshold ranges of target intraocular pressure, temperature and electromyographic activity based on the processed data; for example: the target intraocular pressure range is 10mmHg-20mmHg, the target temperature range is 30℃-37℃, and the target electromyographic activity range is 100μV-200μV.

[0030] The error calculation module is configured to initialize the PID parameters Kp, Ki, Kd and the initial values ​​of the vibration frequency and intensity according to the preset threshold ranges of the target intraocular pressure, temperature and electromyographic activity; for example: the dynamic adjustment range of the vibration frequency is: 10Hz-100Hz, and the dynamic adjustment range of the vibration intensity is: 0.1N-1N; the real-time collected intraocular pressure data, temperature data and electromyographic activity data are compared with the preset thresholds to obtain the error value between the two; for example: the following data are obtained from the monitoring module: real-time intraocular pressure: 15mmHg, real-time temperature: 35℃, real-time electromyographic activity: 150μV; assuming the thresholds are as follows: target intraocular pressure: 18mmHg, target temperature: 36℃, target electromyographic activity: 180μV; calculate the error: intraocular pressure error: 18-15=3mmHg, temperature error: 36-15=1℃, electromyographic activity error: 180-150=30μV.

[0031] The dynamic adjustment module is configured to calculate and output the control amount of the vibration frequency and intensity based on the error value between the two through the PID formula, and dynamically calculate and adjust the vibration frequency and intensity of the massage module according to the output control amount.

[0032] Obtain the control quantities of vibration frequency and intensity calculated by PID formula, as well as intraocular pressure error, temperature error and myoelectric activity error; Calculate new vibration frequency and intensity parameters in real time based on control output; Based on the new vibration frequency and intensity parameters, the vibration frequency and intensity are dynamically adjusted to ensure that the vibration frequency and intensity are within the threshold range.

[0033] Specifically, since the patient's eye condition may change at any time, it is necessary to calculate and adjust the vibration frequency and intensity in real time to adapt to eye changes and ensure the comfort and effectiveness of the massage effect. If the control quantity preliminarily calculated by the PID algorithm is always applied, it may cause sudden changes in vibration frequency and intensity, which will cause discomfort to the patient. Through real-time calculation and dynamic adjustment of parameters, a smooth transition of vibration frequency and intensity can be achieved, and the range of vibration frequency and intensity can be limited to prevent them from exceeding the safe range. Secondly, during long-term operation, the cumulative error will affect the massage effect. By dynamically adjusting the parameters, the cumulative error can be gradually corrected, which helps to improve the intelligence level of the eye care device and the patient experience.

[0034] At the same time, the control quantities of vibration frequency and intensity calculated by PID formula include: Retrieve the real-time intraocular pressure error, temperature error and myoelectric activity error during the PID process; Obtaining the error standard deviation and error median of the intraocular pressure error, the temperature error, and the myoelectric activity error according to the real-time error values ​​corresponding to the intraocular pressure error, the temperature error, and the myoelectric activity error; Using the error standard deviation and error median value corresponding to the intraocular pressure error, temperature error and myoelectric activity error, respectively, the error response parameters corresponding to the intraocular pressure error, temperature error and myoelectric activity error are set; The multimodal error fusion factor is obtained by using the error response parameters corresponding to the intraocular pressure error, temperature error and myoelectric activity error. Among them, E 01 、E 02 and E 03 They represent the error response parameters corresponding to intraocular pressure error, temperature error and myoelectric activity error respectively; w 01 、w 02 and w 03 They represent the weights of the error response parameters corresponding to the intraocular pressure error, temperature error, and myoelectric activity error respectively; The multimodal error fusion factor is used to control a PID vibrator parameter generator to obtain control quantities of vibration frequency and intensity.

[0035] The control amount of the vibration frequency and intensity is obtained by the following formula: Among them, Δf and ΔA represent the control quantities of vibration frequency and intensity respectively; K f and K A Respectively represent the adjustment gains corresponding to the vibration frequency and intensity, preferably, K f =2Hz / unit,K A =0.3G / unit; K c represents the intraocular pressure-myoelectric coupling coefficient, with a value of 0.5; K d Indicates the temperature change rate suppression factor, with a value of 1.2; dE 02 / dt represents the temperature error change rate; Δf max Indicates the maximum frequency adjustment range; ΔA max Indicates the maximum intensity adjustment range.

[0036] Then, according to the control output, new vibration frequency and intensity parameters are calculated in real time. The new vibration frequency and intensity parameters are the sum of the initial values ​​of the vibration frequency and intensity and the control amounts of the vibration frequency and intensity.

[0037] The technical effects of the above-mentioned technical solution are as follows: first, real-time error is retrieved, then analyzed through error standard deviation and median value, and unique response parameters are set for different errors. This allows for accurate capture of subtle changes in intraocular pressure, temperature, and electromyographic activity errors, improving error perception and processing accuracy and making the system more sensitive to complex physiological signal fluctuations. A multimodal error fusion factor is constructed, integrating the response parameters and weights of intraocular pressure, temperature, and electromyographic activity errors. This adapts to multiple physiological indicator coupling scenarios, comprehensively considering the impact of each error on vibration control, and aligning the control logic with the multi-factor interactive characteristics of the human physiological system. The formula proposed in this embodiment combines parameters such as adjustment gain, coupling coefficient, and suppression factor to accurately calculate the vibration frequency and intensity control variables. This allows for dynamic and quantitative control of vibration parameters based on physiological errors, allowing the PID vibrator to output vibration stimulation adapted to the physiological state. The vibration frequency and intensity parameters are updated in real time based on the control output, forming a closed-loop control system that rapidly responds to changes in physiological errors, continuously optimizes vibration stimulation, ensures dynamic and timely adaptation to the physiological state, and improves the real-time and effectiveness of system control.

[0038] Furthermore, by incorporating parameters related to multi-dimensional errors such as intraocular pressure, temperature, and electromyography (e.g., error response parameters and error change rates) into the formula, vibration frequency and intensity control can synergistically respond to various physiological errors, adapting to the multi-factor interactions in complex physiological environments and making the control more aligned with the multi-faceted feedback requirements of the human physiological system. The introduction of error change rates (e.g., temperature error change rate) and various adjustment coefficients (adjustment gain, coupling coefficient, suppression factor, etc.) allows for real-time capture of the dynamic changes in physiological errors, accurately calculating the adjustments to vibration frequency and intensity. This allows for dynamic fine-tuning of vibration parameters in response to physiological conditions, improving control accuracy and real-time performance. Combined with the maximum adjustment range (maximum frequency and intensity adjustment range), reasonable constraints are placed on the control of vibration frequency and intensity. This ensures effective parameter adjustment in response to physiological errors while preventing discomfort or damage to the human body caused by over-adjustment, ensuring that the vibration output adapts to physiological control needs within an effective and safe range.

[0039] Specifically, the error response parameters corresponding to the intraocular pressure error, temperature error, and myoelectric activity error are set respectively using the error standard deviation and error median value corresponding to the intraocular pressure error, temperature error, and myoelectric activity error, including: Retrieve the standard deviation and median error of the intraocular pressure error; Normalizing the error standard deviation and the error median of the intraocular pressure error to obtain the normalized error standard deviation and error median of the intraocular pressure error; Setting an error response parameter corresponding to the intraocular pressure error using the error standard deviation and the error median of the normalized intraocular pressure error; The error response parameter corresponding to the intraocular pressure error is obtained by the following formula: Among them, E 01 represents the error response parameter corresponding to the intraocular pressure error; e 01p and e 01z Indicates the standard deviation and median error of the normalized intraocular pressure error; Retrieve the error standard deviation and error median of the temperature error; Normalizing the error standard deviation and the error median of the temperature error to obtain the normalized error standard deviation and the error median of the temperature error; The maximum allowable temperature error is retrieved and normalized to obtain the normalized maximum allowable temperature error e t ; The maximum allowable temperature error after normalization is e t Perform difference processing on the error intermediate value corresponding to the normalized temperature error to obtain the maximum allowable temperature error e after normalization.t The absolute difference between the mean values ​​of the errors corresponding to the temperature errors ; The maximum allowable temperature error e after the normalization process is used t The absolute difference between the mean values ​​of the errors corresponding to the temperature errors The error response parameter corresponding to the temperature error is set based on the error standard deviation of the temperature error after normalization; The error response parameter corresponding to the temperature error is obtained by the following formula: Among them, E 02 represents the error response parameter corresponding to the temperature error; e 02p and e 02z Represents the standard deviation and median error of the temperature error after normalization; e t Indicates the maximum allowable temperature error after normalization; Get the error standard deviation and error median of the electromyographic activity error; Normalizing the error standard deviation and the error median of the electromyographic activity error to obtain the normalized error standard deviation and the error median of the electromyographic activity error; The normalized myoelectric activity error is processed by the Signum function. When the output value after the Signum function processing is sgn (e 03p ) = 0, then the error response parameter corresponding to the electromyographic activity error is ; When the output value after the Signum function is processed is sgn (e 03p ) is not 0, the error response parameter corresponding to the myoelectric activity error is set using the error standard deviation and the error median of the myoelectric activity error after the normalization process; The error response parameter corresponding to the electromyographic activity error is obtained by the following formula: Among them, E 03 represents the error response parameter corresponding to the EMG activity error; e 03p and e 03z Represents the standard deviation and median error of the normalized EMG error.

[0040] The technical effect of the above technical solution is as follows: by first retrieving the standard deviation and median value of the intraocular pressure, temperature, and electromyographic activity errors, and then normalizing them, the dimensional differences of different error indicators can be eliminated, allowing the error response parameters set subsequently to accurately fit the statistical characteristics of each error, making the parameters more reasonable in representing the errors and laying a solid foundation for multimodal error fusion. Designing dedicated processes to calculate the error response parameters for intraocular pressure, temperature, and electromyographic activity errors can fully explore the unique laws of different types of errors. Taking into account the different mechanisms and changing characteristics of intraocular pressure, temperature, and electromyography in physiological systems, it can achieve refined and differentiated processing of multi-dimensional errors and improve the effectiveness of error utilization. Each error response parameter serves as the basic component of the multimodal error fusion factor. Its precise calculation allows the fusion factor to effectively integrate multiple error information. This allows the subsequent vibration frequency and intensity control based on the fusion factor to comprehensively consider the deviations of multiple physiological indicators of the human body, adapt to the control needs in complex physiological environments, and enhance the scientific and comprehensive nature of the control strategy.

[0041] At the same time, by performing specific operations on the normalized standard deviation and median value of the IOP error, the impact of the IOP error can be reasonably quantified, and the statistical characteristics of the IOP error can be converted into a parameter form suitable for subsequent fusion and control. This effectively extracts valuable information from the IOP error for vibration control, making the IOP error's regulation of vibration parameters more consistent with its physiological impact logic. Furthermore, by introducing related operations such as the hyperbolic tangent function and the maximum allowable temperature error, the effect of the temperature error can be nonlinearly constrained and reasonably scaled, reflecting the actual impact of the temperature error while avoiding parameter loss caused by extreme errors. This allows the contribution of the temperature error to vibration control to be dynamically adjusted within a reasonable range, adapting to the characteristics of the impact of temperature error changes on physiological systems. At the same time, by combining the sign function with the square root operation, the direction of the EMG error (positive and negative deviations) can be clearly distinguished, and the effect of the error size on the response parameters can be reasonably characterized. The polarity and amplitude information of the EMG error can be accurately captured, so that the role of the EMG error in vibration control can be accurately reflected, which is consistent with the characteristics of EMG signals in regulating movement and state in physiological feedback. Moreover, when sgn(e 03p )=0, which means that the standard deviation of the EMG error is in a special "zero sign" state (which can be understood as the error has no obvious positive or negative bias or is in critical balance). (Using the normalized error median value e 03z Calculation), which can be specifically adapted to this special scenario, avoiding parameter calculation blanks or unreasonable default values ​​due to the sign function output being 0 (such as directly assigning 0 may ignore the information contained in the error intermediate value), so that the system still has reasonable error response parameter output under the special state of electromyographic error, enhancing the robustness of the entire error processing process to complex and extreme situations, and ensuring the stable operation of subsequent control logic based on this parameter (such as multimodal fusion, equipment control, etc.).03z As the normalized median value of the electromyographic activity error, it carries key information such as the error central trend. 03p )=0 (the sign feature of the standard deviation disappears), and E is constructed by multiplying it by a coefficient of 0.1. 03 , which preserves information about the intermediate error value, ensuring that the error response parameter can still reflect the core characteristics of the EMG error to a certain extent under special conditions, maintaining the continuity of the error representation. This allows for smoother parameter transitions when the error state switches (from signed to unsigned), avoiding significant fluctuations in the subsequent control strategy caused by sudden changes in characteristics and ensuring a more consistent and stable representation and utilization of the EMG error by the system. Furthermore, the setting of a coefficient of 0.1 can be considered a weighting adjustment for the intermediate error value in special scenarios. When the sign characteristic of the EMG error disappears, this coefficient weakens (compared to the calculations possible under other normal sign states) but does not eliminate the influence of the intermediate error value. This not only reflects the special nature of this situation but also allows for flexible adjustment of the contribution of the intermediate error value to the final error response parameter based on actual physiological or system requirements (for example, the impact of the EMG signal on overall control should be appropriately reduced under certain conditions). This allows parameter design to better meet the actual needs of EMG signal processing and associated control, improving the adaptability and accuracy of the entire technical solution for EMG error processing.

[0042] The selection module is configured to select the desired temperature mode and monocular / binocular mode through physical button 3 according to postoperative needs; the selection module includes: The mode confirmation module is configured to prompt the patient of the currently selected single or double eye mode through the switch status display of the two indicator lights 4, and prompt the patient of the currently selected temperature mode through the color of the lamp tubes of the two indicator lights 4; for example: when the light of the indicator light 4 is turned on, it means that the massage function is turned on, otherwise the light is turned off, it means that the massage function is turned off; and "Z" and "Y" are marked on one side of the two indicator lights 4, representing the left eye and the right eye respectively. If the light of the indicator light 4 marked "Z" is turned on, it means that the massage function of the left eye is turned on, and vice versa; for example: when the lamp tube of the indicator light 4 is red, it means the heating mode, and when the indicator light 4 is blue, it means the cooling mode.

[0043] The mode clearing module is configured to automatically clear the massage mode set by the physical button 3 in the previous round after the eye massager 1 is turned off based on the physical button 3, so that the eye massager 1 can automatically return to the initial parameters when it is used next time.

[0044] The beneficial effects achieved by the above content are: by real-time monitoring of intraocular pressure, temperature and electromyographic activity data, and comparing them with preset thresholds to calculate the error value, and then using the PID algorithm to dynamically adjust the massage parameters, thereby forming a closed-loop control, it can ensure that the vibration frequency and intensity are always within a safe and effective range, thereby improving the personalization and adaptability of the eye massager, and ensuring that patients have a comfortable and effective massage experience; at the same time, it reduces manual intervention, enhances the intelligence level of the eye massager, and realizes automated and precise eye care.

[0045] The integrated module is configured to connect the eye massager 1 to the medical terminal based on wireless communication technology, and create a patient file based on the medical terminal to record and analyze the patient's key physiological data and massage parameters during the massage process.

[0046] The storage module is configured to transmit the intraocular pressure data, temperature data and electromyographic activity data monitored by the patient during the massage process, as well as the vibration frequency parameters and intensity parameters implemented during the massage process, to the patient file of the medical terminal for storage based on wireless communication technology. It not only provides patients with personalized and continuous nursing services, but also automatically updates and maintains patient files to ensure the timeliness and relevance of the data; at the same time, it also optimizes storage space by regularly cleaning up files that have not been used for a long time, providing medical staff with strong data support for better patient management and treatment effect evaluation.

The initial settings are adjusted based on the patient's feedback and current eye condition to optimize the massage effect.

[0049] The beneficial effects achieved by the above content are: by analyzing and calculating the patient's intraocular pressure, temperature, and electromyographic activity data as well as the vibration frequency and intensity parameters, it is ensured that each treatment is adjusted based on the results of previous treatments, thereby achieving refined management and personalized adjustment of the patient's eye care process, improving patient satisfaction and the targetedness and effectiveness of massage therapy; at the same time, it provides medical staff with intuitive data support to help them better understand and track the patient's recovery progress.

[0050] Working Principle: By collecting intraocular pressure, temperature and electromyographic activity data in real time, the vibration frequency and intensity of the massage module are dynamically adjusted using the PID algorithm to achieve a personalized massage experience. At the same time, the functional module uses semiconductor Peltier elements to provide precise temperature control to promote blood circulation or apply cold compresses after surgery. Patients can also interact with the selection module through physical buttons and indicator lights to select the desired temperature mode and massage mode, such as: single eye or double eye, thus achieving intelligent, comfortable eye care that adapts to the needs of different users.
