[0068] The massage care unit A comprises a massage module and a function module.

[0069] The massage module is configured to simulate professional massage methods to perform traditional Chinese medicine acupoint massage based on a linear resonant motor array, relax eye muscle and relieve visual fatigue.

[0070] The function module is configured to provide heating and refrigeration functions based on a semiconductor Peltier element, heating is used for promoting eye blood circulation, and refrigeration is used for postoperative cold compress, so that various massage modes are provided to meet the needs of different use scenarios.

[0071] The central processing unit B comprises a monitoring module, a control module, a selection module, an integration module, a storage module, an analysis module and a calling module.

[0072] The monitoring module is configured to be composed of a microtonometer, a temperature sensor and an electromyographic sensor, is installed on the inner side of the massage care unit A and is in contact with the eye; the microtonometer is used for monitoring real-time intraocular pressure data; the temperature sensor is used for monitoring real-time temperature data of the eye, the temperature sensor adopts a thermistor, and the electromyographic sensor is used for monitoring real-time electromyographic activity data of the eye muscle.

[0073] The control module is configured to adopt a microcontroller, dynamically adjusts the vibration frequency and intensity of the massage module according to the monitoring data and in combination with postoperative needs through a PID algorithm; the control module comprises:

[0074] The sample acquisition module is configured to acquire historical intraocular pressure data, temperature data and electromyographic activity data of multiple patients and pre-processes the data as data samples.

[0075] a threshold setting module configured to preset a threshold range of target intraocular pressure, temperature and myoelectric activity based on the processed data; for example, the target intraocular pressure range is 10 mmHg-20 mmHg, the target temperature range is 30℃-37℃, and the target myoelectric activity range is 100 μV-200 μV.

[0076] an error calculation module configured to initialize PID parameters Kp, Ki, Kd and initial values of vibration frequency and intensity according to the preset threshold range of target intraocular pressure, temperature and myoelectric activity; for example, the dynamic adjustment range of vibration frequency is 10 Hz-100 Hz, and the dynamic adjustment range of vibration intensity is 0.1 N-1 N; compare the real-time collected intraocular pressure data, temperature data and myoelectric activity data with the preset threshold to obtain the error value between them; for example, the following data are obtained from the monitoring module: real-time intraocular pressure: 15 mmHg, real-time temperature: 35℃, and real-time myoelectric activity: 150 μV; assuming the threshold values are as follows: target intraocular pressure: 18 mmHg, target temperature: 36℃, and target myoelectric activity: 180 μV; calculate the error: intraocular pressure error: 18-15=3 mmHg, temperature error: 36-15=1℃, and myoelectric activity error: 180-150=30 μV.

[0077] a dynamic adjustment module configured to calculate and output the control amount of vibration frequency and intensity by a PID formula based on the error value between them, and dynamically calculate and adjust the vibration frequency and intensity of the massage module according to the output control amount.

[0078] obtain the control amount of vibration frequency and intensity calculated by the PID formula, and the intraocular pressure error, temperature error and myoelectric activity error;

[0079] calculate new vibration frequency and intensity parameters in real time according to the control output;

[0080] based on the new vibration frequency and intensity parameters, dynamically adjust the vibration frequency and intensity to ensure that the vibration frequency and intensity are within the threshold range.

[0081] Specifically, since the eye condition of the patient can change at any time, it is necessary to calculate and adjust the vibration frequency and intensity in real time to adapt to the eye changes and ensure the comfort and effectiveness of the massage effect; if the control amount calculated by the PID algorithm is always applied, it may cause sudden changes in vibration frequency and intensity, which may cause discomfort to the patient; by real-time calculation and dynamic adjustment of parameters, smooth transition of vibration frequency and intensity can be realized, and the range of vibration frequency and intensity is limited to prevent exceeding the safe range. Secondly, during long-term operation, accumulated errors will affect the massage effect, and by dynamically adjusting the parameters, the accumulated errors can be gradually corrected, which helps to improve the intelligent level of the eye care device and the patient experience.

[0082] At the same time, the control amount of the vibration frequency and intensity calculated by the PID formula includes:

[0083] The real-time intraocular pressure error, temperature error and myoelectric activity error in the PID process are called;

[0084] The error standard deviation and error median of the intraocular pressure error, temperature error and myoelectric activity error are obtained according to the real-time error values corresponding to the intraocular pressure error, temperature error and myoelectric activity error;

[0085] The error response parameters corresponding to the intraocular pressure error, temperature error and myoelectric activity error are set respectively by using the error standard deviation and error median corresponding to the intraocular pressure error, temperature error and myoelectric activity error;

[0086] The multi-modal error fusion factor is obtained by using the error response parameters corresponding to the intraocular pressure error, temperature error and myoelectric activity error ; wherein E 01 , E 02 and E 03 represent the error response parameters corresponding to the intraocular pressure error, temperature error and myoelectric activity error respectively; w 01 , w 02 and w 03 represent the weights of the error response parameters corresponding to the intraocular pressure error, temperature error and myoelectric activity error respectively;

[0087] The control amount of the vibration frequency and intensity is obtained by using the multi-modal error fusion factor to control the PID vibrator parameter generator.

[0088] Wherein, the control amount of the vibration frequency and intensity is obtained by the following formula:

[0089]

[0090] Wherein, Δf and ΔA represent the control amount of the vibration frequency and intensity respectively; K f and K A represent the adjustment gain corresponding to the vibration frequency and intensity, preferably, K f = 2 Hz / unit, K A = 0.3 G / unit; K c represents the intraocular pressure-myoelectric coupling coefficient, and the value is 0.5; K d represents the temperature change rate suppression factor, and the value is 1.2; dE 02 / dt represents the temperature error change rate; Δf max represents the maximum frequency adjustment range; ΔA max represents the maximum intensity adjustment range.

[0091] Then, according to the control output, a new vibration frequency and intensity parameter is calculated in real time, and the new vibration frequency and intensity parameter is the sum of the initial value of the vibration frequency and the intensity and the control amount of the vibration frequency and the intensity.

[0092] The technical effects of the above technical solutions are: first, the real-time error is retrieved, then the error standard deviation and the median value are analyzed, and the error response parameters are set for different errors, which can accurately capture the subtle changes of the intraocular pressure, temperature, and electromyographic activity errors, improve the error perception and processing accuracy, and make the system more sensitive to complex physiological signal fluctuations. The multi-modal error fusion factor is constructed, the intraocular pressure, temperature, and electromyographic activity error response parameters and weights are integrated, which can adapt to the multi-physiological index coupling scene, comprehensively consider the influence of each error on vibration control, and make the control logic fit the multi-factor interaction characteristics of the human physiological system. The above formula combined with the adjustment gain, coupling coefficient, and suppression factor in the embodiment can accurately calculate the vibration frequency and intensity control amount, dynamically and quantitatively regulate the vibration parameters according to the physiological error, and make the PID vibrator output adapt to the vibration stimulation of the physiological state. According to the control output, the vibration frequency and intensity parameters are updated in real time to form a closed-loop control, which can quickly respond to physiological error changes, continuously optimize the vibration stimulation, ensure dynamic and timely adaptation to the physiological state, and improve the real-time and effectiveness of system control.

[0093] On the other hand, the parameters related to the multi-dimensional errors such as intraocular pressure, temperature, and electromyography (such as error response parameters, error change rate, etc.) are integrated into the formula, so that the vibration frequency and intensity control can respond to multiple physiological errors, adapt to the multi-factor interaction in complex physiological environments, and make the control more suitable for the multi-element feedback requirements of the human physiological system. The introduction of error change rate (such as temperature error change rate) and various adjustment coefficients (adjustment gain, coupling coefficient, suppression factor, etc.) can capture the dynamic changes of physiological errors in real time, accurately calculate the adjustment amount of vibration frequency and intensity, and dynamically fine-tune the vibration parameters according to the physiological state, thereby improving the accuracy and real-time of the control. Combined with the maximum adjustment range (maximum frequency and intensity adjustment range), the control amount of the vibration frequency and intensity is reasonably constrained, which not only ensures that the physiological error can be effectively responded to for parameter adjustment, but also avoids excessive adjustment that may cause discomfort or damage to the human body, so that the vibration output can adapt to the physiological regulation requirements within an effective and safe range.

[0094] Specifically, the error standard deviation and the error median value corresponding to the intraocular pressure error, the temperature error, and the electromyographic activity error are used to set the error response parameters corresponding to the intraocular pressure error, the temperature error, and the electromyographic activity error, respectively, including:

[0095] The error standard deviation and the error median value of the intraocular pressure error are retrieved.

[0096] The error standard deviation and the error median value of the intraocular pressure error are normalized to obtain the normalized error standard deviation and error median value of the intraocular pressure error.

[0097] The error standard deviation and the error median of the normalized intraocular pressure error are used to set an error response parameter corresponding to the intraocular pressure error;

[0098] The error response parameter corresponding to the intraocular pressure error is obtained through the following formula:

[0099]

[0100] Wherein, E 01 represents the error response parameter corresponding to the intraocular pressure error; e 01p and e 01z represent the error standard deviation and the error median of the normalized intraocular pressure error;

[0101] The error standard deviation and the error median of the temperature error are retrieved;

[0102] The error standard deviation and the error median of the temperature error are normalized to obtain the error standard deviation and the error median of the normalized temperature error;

[0103] The maximum allowable temperature error is retrieved and normalized to obtain the normalized maximum allowable temperature error e t ;

[0104] The normalized maximum allowable temperature error e t and the error median corresponding to the normalized temperature error are subjected to difference processing to obtain the absolute difference between the normalized maximum allowable temperature error e t and the error median corresponding to the temperature error ;

[0105] The absolute difference between the normalized maximum allowable temperature error e t and the error median corresponding to the temperature error The error standard deviation of the normalized temperature error is combined to set an error response parameter corresponding to the temperature error;

[0106] The error response parameter corresponding to the temperature error is obtained through the following formula:

[0107]

[0108] Wherein, E 02 represents the error response parameter corresponding to the temperature error; e 02p and e 02z represent the error standard deviation and the error median of the normalized temperature error; e t represents the normalized maximum allowable temperature error;

[0109] retrieve an error standard deviation and an error median value of the electromyographic activity error;

[0110] normalize the error standard deviation and the error median value of the electromyographic activity error, to obtain a normalized error standard deviation and a normalized error median value of the electromyographic activity error;

[0111] perform Signum function processing on the normalized electromyographic activity error, and when an output value after the Signum function processing is sgn (e 03p ) = 0, set an error response parameter corresponding to the electromyographic activity error to 0; ;

[0112] when the output value after the Signum function processing is sgn (e 03p ) not equal to 0, set the error response parameter corresponding to the electromyographic activity error by using the normalized error standard deviation and the normalized error median value of the electromyographic activity error;

[0113] wherein the error response parameter corresponding to the electromyographic activity error is obtained by the following formula:

[0114]

[0115] wherein E 03 represents the error response parameter corresponding to the electromyographic activity error; e 03p and e 03z represent the normalized error standard deviation and the normalized error median value of the electromyographic activity error.

[0116] The technical effect of the above technical solution is that, by first retrieving the standard deviation and the median value of the intraocular pressure, the temperature, and the electromyographic activity error, and then performing normalization processing, the dimension differences of different error indicators can be eliminated, the error response parameters set subsequently can accurately fit the statistical characteristics of each error, the representation of the parameters on the errors is more reasonable, and a reliable foundation is laid for multi-modal error fusion. For the intraocular pressure, the temperature, and the electromyographic activity error, error response parameters are respectively designed by using special processes, the unique laws of different types of errors can be fully tapped, the different action mechanisms and change characteristics of the intraocular pressure, the temperature, and the electromyographic activity in the physiological system are considered, and fine and differentiated processing of multi-dimensional errors is realized, thereby improving the effectiveness of error utilization. The accurate calculation of each error response parameter as a basic component of a multi-modal error fusion factor can enable the fusion factor to effectively integrate multiple error information, so that subsequent vibration frequency and intensity control based on the fusion factor can comprehensively consider the deviations of multiple physiological indicators of the human body, adapt to the control requirements in complex physiological environments, and enhance the scientificity and comprehensiveness of the control strategy.

[0117] Meanwhile, by performing specific operations on the normalized intraocular pressure error standard deviation and median value, the influence degree of the intraocular pressure error can be reasonably quantified, the statistical characteristics of the intraocular pressure error can be converted into a parameter form suitable for subsequent fusion and control, valuable information in the intraocular pressure error that is useful for vibration control can be effectively extracted, and the regulation of the intraocular pressure error on the vibration parameter is more in line with the physiological influence logic. Moreover, by introducing hyperbolic tangent function and maximum allowed temperature error and related operations, the effect of the temperature error can be nonlinearly constrained and reasonably scaled, which not only reflects the actual influence of the temperature error, but also avoids extreme error leading to parameter out of control, so that the contribution of the temperature error to the vibration control is dynamically adjusted within a reasonable range, adapting to the characteristics of the influence of temperature error changes on the physiological system. At the same time, by combining the sign function with the square root operation, the direction (positive or negative deviation) of the electromyographic activity error can be clearly distinguished, and the effect of the error size on the response parameter can be reasonably represented, so that the polarity and amplitude information of the electromyographic activity error can be accurately captured, and the role of the electromyographic activity error in the vibration control can be accurately reflected, which is in line with the characteristics of the electromyographic signal in the physiological feedback for action and state regulation. Moreover, when sgn(e 03p )=0, it means that the standard deviation related characteristics of the electromyographic activity error are in a special "zero symbol" state (which can be understood as no obvious positive or negative deviation or at critical balance). At this time, by (using the normalized error median value e 03z ), this special scenario can be targeted to adapt, avoiding parameter calculation blank or unreasonable default value (such as assigning 0 directly may ignore the information contained in the error median value) due to the sign function output being 0, so that the system still has reasonable error response parameter output in the special state of the electromyographic error, enhancing the robustness of the entire error processing flow to complex and extreme situations, and ensuring the stable operation of the subsequent control logic (such as multi-modal fusion, device regulation, etc.) based on the parameter.e 03z As the normalized electromyographic activity error median value, it carries key information such as error concentration trend. Even if sgn(e 03p )=0 (the standard deviation related symbol feature disappears), by multiplying a coefficient of 0.1 to construct E 03The information of the error intermediate value can be reserved, so that the error response parameter can still reflect the core characteristics of the myoelectric error to a certain extent in a special state, and the continuity of the error representation is maintained. In this way, when the error state switches (from a signed feature to a non-signed feature), the parameter transition is smoother, avoiding large fluctuations in the subsequent control strategy due to feature mutations, and ensuring that the system's representation and use of myoelectric error are more coherent and stable. At the same time, the setting of the coefficient 0.1 can be regarded as a kind of weight adjustment of the error intermediate value in a special scenario. When the signed feature of the myoelectric activity error disappears, the influence of the error intermediate value is weakened (compared to the possible operation in other normal signed states) but not discarded through this coefficient, which not only reflects the particularity of this special situation, but also allows for flexible adjustment of the contribution of the error intermediate value to the final error response parameter according to actual physiological or system requirements (such as the need to appropriately reduce the impact of the myoelectric signal on overall control in a particular state), making the parameter design more suitable for the actual needs of myoelectric signal processing and related control, and improving the adaptability and accuracy of the entire technical solution for myoelectric error processing.

[0118] The selection module is configured to select the required temperature mode and single or double eye mode through the physical button 3 according to the postoperative needs. The selection module includes:

[0119] The mode confirmation module is configured to display the currently selected single or double eye mode through the on-off state of the two indicator lights 4, and display the currently selected temperature mode through the color of the lamp tube of the two indicator lights 4. For example, if the light of the indicator light 4 is on, it means that the massage function is on, and vice versa. On one side of the two indicator lights 4, there are "Z" and "Y" marks respectively, representing the left eye and the right eye. If the light of the "Z" indicator light 4 is on, it means that the left eye massage function is on, and vice versa. For another example, if the lamp tube of the indicator light 4 is red, it means heating mode, and if the indicator light 4 is blue, it means cooling mode.

[0120] The mode clearing module is configured to automatically clear the massage mode set on the physical button 3 in the last round after the eye massager 1 is turned off based on the physical button 3, so that the initial parameters of the eye massager 1 can be automatically returned when the eye massager 1 is used again next time.

[0121] The above-mentioned beneficial effects: by real-time monitoring of intraocular pressure, temperature and myoelectric activity data, and comparing with the preset threshold to calculate error value, and then dynamically adjusting the massage parameters by using PID algorithm, a closed-loop control is formed, which can ensure that the vibration frequency and intensity are always within a safe and effective range, thereby improving the individualization and adaptability of the eye massager, and ensuring that the patient obtains a comfortable and effective massage experience; at the same time, reducing manual intervention, enhancing the intelligent level of the eye massager, realizing automatic and precise eye care.

[0122] The integrated module is configured to connect the eye massager 1 to a medical terminal based on wireless communication technology, and to create patient profiles based on the medical terminal in order to record and analyze key physiological data and massage parameters of the patient during the massage process.

[0123] The storage module is configured to transmit intraocular pressure, temperature, and electromyographic activity data monitored during the massage, as well as vibration frequency and intensity parameters implemented during the massage, to the patient's file on the medical terminal via wireless communication technology. This not only provides patients with personalized and continuous nursing services and automatically updates and maintains patient files to ensure the timeliness and relevance of the data, but also optimizes storage space by regularly cleaning up long-term unused files, providing strong data support for medical staff to better manage patients and evaluate treatment effectiveness.

[0124] The analysis module is configured to align the patient's intraocular pressure, temperature, and electromyographic activity data with the corresponding vibration frequency and intensity parameters after each massage session, and plot these parameters as a line graph. It then uses an averaging method to calculate the average of the vibration frequency and intensity parameters applied in each session, storing these averages in the patient's file as the initial vibration frequency and intensity parameters for the next massage. After the next massage session, once a new average frequency and intensity value is calculated, the previously obtained average frequency and intensity values ​​are modified to reflect the new values. This process is repeated until the patient recovers. Based on regular screening of patient files via medical terminals, files of patients who have not used the eye massager for nearly three months are deleted to optimize storage space.

[0125] The module is configured to automatically retrieve the average vibration frequency and intensity recorded in the patient's file when the patient receives their next massage. These values ​​will be used as the initial vibration frequency and intensity parameters for this massage. The initial settings will be adjusted based on the patient's feedback and the current state of their eyes to optimize the massage effect.

[0126] The beneficial effects achieved by the above are as follows: By analyzing and calculating the patient's intraocular pressure, temperature, and electromyographic activity data, along with vibration frequency and intensity parameters, it is ensured that each treatment is adjusted based on the effects of previous treatments. This enables refined management and personalized adjustments to 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, helping them to better understand and track the patient's recovery process.

[0127] Working principle: By real-time collection of intraocular pressure, temperature and electromyographic activity data, the PID algorithm is used to dynamically adjust the vibration frequency and intensity of the massage module, realizing personalized massage experience; at the same time, the functional module uses semiconductor Peltier elements to provide accurate temperature control for promoting blood circulation or postoperative cold compress; patients can also interact with the selection module through physical buttons and indicator lights to select the required temperature mode and massage mode, such as: single eye or double eyes, so as to realize intelligent, comfortable, and adaptive eye care for different user needs.
