Description

Technical Field

[0001] This invention belongs to the field of surgical rehabilitation technology, and in particular relates to an auxiliary rehabilitation system and method after retinal surgery. Background Technology

[0002] With the widespread use of smartphones and the increasing informatization of society, people's eye strain has increased significantly. The overall eye health of the population is becoming increasingly serious. Research shows that the incidence of retinal detachment is rising. The number of cases is large, and the affected population is specific. Furthermore, with population aging and the increasing prevalence of diabetes among different age groups, diabetic retinopathy will become a public health problem. Currently, the main challenges in post-retinal detachment surgery rehabilitation are concentrated in the following aspects:

[0003] (a) Real-time monitoring of patient status is difficult

[0004] In the postoperative rehabilitation of retinal detachment surgery, there are currently difficulties in real-time monitoring of the patient's condition. The first difficulty lies in monitoring the patient's posture during the rehabilitation process. Patients undergoing retinal surgery require one to several months of home rehabilitation in specific postures. During this home period, doctors need to understand whether the patient's daily posture is conforming to the guidelines for achieving the desired rehabilitation effect. The second difficulty is in monitoring the pressure at the retinal lesion sites. Since most retinal lesions are located in the fundus, but current intraocular pressure monitoring methods only measure the external pressure in the anterior part of the eye, they cannot determine the pressure at the fundus lesion sites within the eye.

[0005] (ii) Long postoperative recovery time and high demand for precise nursing care

[0006] Because the recovery process for this type of surgery is characterized by a long recovery period and home-based rehabilitation, it is necessary to implement certain continuous and precise nursing care measures to encourage patients to adhere to effective rehabilitation training. Our aim is:

[0007] (1) Solve the current problem of not being able to monitor intraocular pressure;

[0008] (2) To meet the continued care needs of patients undergoing home rehabilitation;

[0009] (3) To achieve the goal of doctors monitoring patients’ home rehabilitation status.

[0010] Existing technologies for assistive rehabilitation after retinal surgery primarily rely on single-angle monitoring instruments. These instruments simply vibrate to alert the patient to adjust their position when their head angle changes. Single-angle monitors have several drawbacks. They lack the ability to provide intelligent data analysis based on the patient's bubble model and eyeball analysis. Doctors struggle to determine personalized treatment plans, cannot provide suitable rehabilitation positions, and cannot set initial and warning angle values ​​for the monitor. Before this advanced system was available, doctors could only determine the approximate location of the lesion and then formulate a general patient position. This position was typically prone and allowed movement within a ±45° range, which meant that intraocular fluid could potentially reach the detachment site, thus affecting the quality of rehabilitation. The lack of intelligent voice prompts to guide patients on proper positioning makes it difficult for them to adjust their positions promptly; the inability to set an intelligent "rest mode" prevents the voice and vibration modules from going into sleep mode while maintaining real-time angle monitoring; the inability to intelligently set initial values ​​via a mini-program makes it impossible to transmit patient angle monitoring data to doctors in real time, and the lack of data analysis and processing makes it difficult for doctors to understand the patient's recovery progress and develop personalized initial positioning and rehabilitation plans; the absence of an intelligent call system means that if the patient fails to adjust their position independently, the administrator (nurse station staff or family guardians) cannot be notified to intervene in a timely manner, resulting in a prolonged recovery period for the patient. Summary of the Invention

[0011] The technical problem to be solved by the present invention is to provide an auxiliary rehabilitation system and method after retinal surgery, which solves the problems of existing technologies having single functions, lacking intelligent human-computer interaction functions, and lacking doctor-patient interaction.

[0012] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] A post-retinal surgery rehabilitation system includes:

[0014] An eye bubble analysis device is used to analyze the distribution area of ​​bubbles in the patient's eye after surgery, and to obtain the patient's postoperative rehabilitation posture information;

[0015] Angle monitor is used to monitor the angle of a patient's head.

[0016] Among them, based on the rehabilitation posture information and the patient's head angle, the rehabilitation posture is learned through posture projection correction, voice correction and vibration direction reminder to carry out posture rehabilitation.

[0017] Preferably, the device also includes: an intelligent call device, which is used to issue an alarm when the patient's head is detected to be shifting; and if the patient's head shifting time exceeds a preset time, it will acquire the patient's room number, the direction and angle of head shift, and the shifting time data and transmit them to the nurse station receiving terminal.

[0018] Preferably, the eyeball bubble analysis device includes:

[0019] The simulation unit is used to simulate the internal conditions of the eyeball using COMSOL to obtain an eyeball model;

[0020] The first determining unit is used to obtain information on the relationship between intraocular bubbles and lesion sites of retinal detachment based on an eyeball model;

[0021] The second determining unit is used to determine the rehabilitation position information based on the relationship information.

[0022] As a preferred option, in "Rest Mode", the no-reminder rest mode is activated, the angle monitor monitors the body position in real time and transmits data, and the sound and vibration reminder functions are not activated; in "Non-Rest Mode", the angle monitor monitors the body position in real time and transmits data, and the normal sound reminder and vibration functions are activated.

[0023] This invention provides an adjunct rehabilitation method after retinal surgery, comprising:

[0024] Step S1: Analyze the distribution area of ​​air bubbles in the patient's eye after surgery using an eye bubble analysis device to obtain the patient's postoperative rehabilitation posture information;

[0025] Step S2: Monitor the patient's head angle using an angle monitor;

[0026] Among them, based on the rehabilitation posture information and the patient's head angle, the rehabilitation posture is learned through posture projection correction, voice correction and vibration direction reminder to carry out posture rehabilitation.

[0027] Preferably, the method also includes: step S3, when a patient’s head is detected to be shifted, an alarm is triggered; at the same time, if the patient’s head shift time exceeds a preset time, the patient’s room number, head shift direction and angle, and shift time data are transmitted to the nurse station receiver.

[0028] Preferably, step S1 includes:

[0029] The internal structure of the eyeball was simulated using COMSOL to obtain an eyeball model.

[0030] Information on the relationship between intraocular bubbles and lesion sites of retinal detachment was obtained based on an eyeball model;

[0031] Based on the relationship information, determine the rehabilitation positioning information.

[0032] As a preferred option, in "Rest Mode", the no-reminder rest mode is activated, the angle monitor monitors the body position in real time and transmits data, and the sound and vibration reminder functions are not activated; in "Non-Rest Mode", the angle monitor monitors the body position in real time and transmits data, and the normal sound reminder and vibration functions are activated.

[0033] This invention is used for hospital and home monitoring. Through an ocular bubble analysis module, it clarifies the relationship between intraocular bubbles and lesion sites of retinal detachment, determines appropriate rehabilitation positions, and establishes initial and warning thresholds for the positional angle. Users can then set the initial values ​​and alarm thresholds for the angle monitor. The angle monitor tracks the patient's positional data in real time. When the patient's position exceeds the warning threshold, a voice and vibration module alerts the patient to adjust their position promptly, and an alarm is transmitted to the nurse station receiver via the nurse station call system. If the patient cannot adjust their position within a certain time, the nurse station is notified for intervention to ensure effective recovery. The angle monitor can be set to a "no-reminder rest mode." This mode can be activated when patients cannot maintain a specific position for extended periods, such as during meals or baths, or when patients with poor sleep quality require longer rest periods at night and cannot tolerate sound and vibration alerts. In this mode, the monitor continues to track the patient's position but does not activate sound or vibration alerts. The patient-side app allows users to contact the patient and their family, view real-time tilt angle data, and view the daily duty roster. The doctor-side web platform can acquire patient positional data in real time, and through cloud-based data analysis and processing, send the data to the doctor's web interface. Doctors can view patient status information in real time, provide timely feedback and adjustments, and formulate treatment plans. The intelligent alarm call device can achieve wireless data transmission via a WIFI module. When it detects a patient's head shift, the system will issue an alarm and start timing. If the head shift time exceeds a set time, it will acquire data such as the patient's room number, head shift direction and angle, and shift time, and transmit the data and alarm information to the administrator's receiving end, notifying the management end (nurse station staff or family guardians) to intervene in a timely manner.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Example 1:

[0041] like Figure 1 As shown, this embodiment of the invention provides an auxiliary rehabilitation system for retinal surgery, including: an eyeball bubble analysis device, an angle monitor and an intelligent call device, a patient-side mini-program and a doctor-side web platform.

[0042] An eye bubble analysis device is used to analyze the distribution area of ​​bubbles in the patient's eye after surgery, and to obtain the patient's postoperative rehabilitation posture information;

[0043] An angle monitor is used to monitor the patient's head angle; based on the rehabilitation posture information and the patient's head angle, the rehabilitation posture is learned through posture projection correction, voice correction and vibration direction reminders to carry out postural rehabilitation.

[0044] The intelligent call device is used to issue an alarm and start a timer when it detects that a patient's head has shifted. If the time the patient's head has shifted exceeds a set time, it obtains the patient's room number, the direction and angle of head shift, and the time of shift, transmits the data to the receiving terminal at the nurse station, and notifies the nurse station staff to intervene in a timely manner.

[0045] During rehabilitation, three intervention measures are used to help patients maintain correct posture: First, timely intervention and reminders are provided using the vibrator and voice system on the angle monitor worn by the patient. Second, the patient summarizes their daily rehabilitation progress through a mini-program for long-term intervention, and doctors provide reminders based on feedback. Doctors analyze and monitor the personal and diagnostic information uploaded by patients through a doctor's web platform and provide necessary rehabilitation tips and answer questions via WeChat. Third, when hospitalized, the intelligent call device will notify the nursing station to intervene promptly if the patient's posture is not corrected within five minutes of the alarm sounding; when recuperating at home, the intelligent call device will notify family caregivers to intervene promptly if the patient's posture is not corrected within five minutes of the alarm sounding.

[0046] In one embodiment of the present invention, the ocular bubble analysis device uses COMSOL to simulate the internal condition of the eyeball. Combined with corrections to a physical model, a complete model of the "bubble" formed by the packing material inside the eyeball is obtained. By processing ultra-wide-angle images of the fundus bubble, a series of identification features are identified, such as the curvature of the bubble's base and the curvature at the junction with the eyeball. Image processing yields the corresponding features of the model, allowing for matching of the bubble model with the appropriate proportion in the model library. The bubble model is imported into the processing system. Doctors operate the eyeball model on a webpage, using red dots to mark the location / range of retinal detachment, and simultaneously determining the margin for the touched retinal detachment location. After setting, the detachment site is combined with the margin, the area the bubble can cover, and the actual angle between the eye axis and the head to derive the corresponding angle on a coordinate system. This angle is directly transmitted to the angle sensor. This coordinate system corresponds to the corresponding rehabilitation position. Doctors can clearly understand the relationship between the ocular bubbles and the lesion site of the retinal detachment. It can precisely determine the patient's position down to the degree, while also allowing for sufficient margin to ensure that fluid inside the patient's eye does not come into contact with retinal lesions, helping to develop personalized rehabilitation treatment plans and guaranteeing effective recovery. For example... Figure 2 As shown, the specific steps include:

[0047] Processing of fundus endoscope images: The patient's fundus endoscope contains images of air bubbles inside the patient's eye. Different air bubbles have different curvatures at their bases. By processing the curvature of the air bubble bases, the volume of the air bubble reflected in the image can be obtained.

[0048] Processing of patient axial length data: Based on the axial length measured by the doctor before surgery, and special lesions such as aphakia or staphyloma, the internal model of the patient's eyeball is determined.

[0049] The model is matched with the eye-bubble model from a database that most closely matches the bubble volume to the patient's eye condition. In this model, the bubble boundary is described by a coordinate system centered on the eyeball.

[0050] Choose whether to enable point mode. Point mode depicts lesion points. If point mode is not enabled, it is observer mode. Observer mode allows you to drag the mouse for a 360-degree panoramic view and zoom in and out using the mouse wheel. In point mode, you can click to mark the boundary points of multiple lesion areas. Connecting multiple boundary points describes the boundary of the retinal lesion area. These points are all described using a coordinate system.

[0051] By comparing the lesion point or lesion area with the bubble boundary, ensuring the lesion point never touches the bubble boundary, an angular range described by a coordinate system is obtained. Subtracting the margin percentage from this range yields the rehabilitation position angular range. The default angular margin is 10%, and the line it represents is called the warning line. The parameters of the warning line can be manually set. A 10% margin means that if the arc connecting the lesion point or lesion area closest to the coordinate axis and the boundary line has an arc length of 1, then the arc connecting the warning line and the boundary line has a length of 0.1.

[0052] The body position is predicted based on the existing pre-trained model, thus providing a reference for the available body positions. This range will be downloaded to the triaxial sensor in the monitoring device for monitoring.

[0053] As one embodiment of the present invention, the angle monitor consists of an angle monitoring module, a wireless communication module, a human-computer interaction module, a sound module, a vibration module, a power supply module, and a control module. By setting the initial value and alarm threshold of the angle monitor, it is possible to set whether to enter a "rest mode" (when a patient cannot maintain a specific posture for a period of time while eating or bathing, or when a patient with poor sleep quality cannot receive sound and vibration reminders at night and needs a longer rest period, a reminder-free rest mode can be activated; the monitor still monitors the posture but does not activate the sound and vibration reminder function, providing the patient with a rest period). During hospitalization or home recuperation, the patient's angle monitoring module monitors the patient's posture data in real time. When the patient's posture exceeds the warning threshold, the voice and vibration modules remind the patient to adjust their posture promptly, and the alarm information is transmitted to the administrator receiving end (nurse station or home monitoring end) via a smart call device. If the patient cannot adjust their posture within a certain time, the nurse or family member is notified for intervention to ensure the patient's recovery.

[0054] The angle monitoring module uses a three-axis inclinometer to acquire the patient's angle data in real time. Based on set warning thresholds, it monitors the patient's position data and sends an alarm command when the angle exceeds the threshold. The wireless communication and human-computer interaction modules use Bluetooth and Wi-Fi to communicate in real time with the patient's mini-program and the doctor's web platform. The monitored angles from the angle monitor are uploaded to the doctor's web platform in real time, and the module receives commands from the human-computer interaction module to set the initial angle. Upon receiving an alarm, the module sends the alarm information to the nurse station system receiver. The sound module, upon receiving an alarm, provides a voice prompt indicating the need to adjust the patient's position, reminding the patient to adjust their position promptly and correctly. The vibration module, upon receiving an alarm, vibrates at a user-set frequency to remind the user to adjust their position accordingly. The control module uses an STM32 chip as its main control chip. Through independent circuit design, a high-performance control module is created, providing overall performance support for the angle monitor.

[0055] The patient wears a head-mounted angle monitor. After the doctor adjusts and fixes the patient's head position, pressing the initialization button will trigger a beep from the device, indicating that the current angle is the initial angle. Pressing the start button will trigger another beep, indicating that the device has begun detecting and recording the angle. The angle monitor has a pause button. When the patient needs to change position for urination or other necessary reasons, pressing this button will trigger a beep from the device, which will then deactivate the alarm for five minutes, but the recording of head angles will continue.

[0056] The head angle deviates from the initial position within the range of -15° to 15°:

[0057] 1) The triaxial tiltmeter monitors and records the head angle every 0.5 seconds, and determines the patient's movement status at this time;

[0058] 2) The head angle deviates from the initial position by ≥15° or ≤-15°:

[0059] In non-"rest mode", if the monitored value of a patient's head angle exceeds the range, the timer in the main control chip will not start if the next monitored angle value returns to the range; otherwise, the timer will start. If the monitored angle value is within the range within 15 seconds after the timer starts, the timer will reset to zero. If the monitored angle value is still outside the range after 15 seconds, the timer will reset to zero. If the monitored angle value is still outside the range after 15 seconds, the direction of the patient's head deviation will be determined, the instrument will activate a voice alarm, the instrument will vibrate, and the timer will start counting from 0, reminding the patient to correctly restore the head angle to the range. If the alarm duration exceeds 5 minutes, the patient's information will be sent to the administrator station via the WIFI network module, reminding the nurse or family member to check the patient. The nurse station will respond to the alarm and help the patient adjust their position. If the patient's head angle returns to the range after the alarm, the timer will reset to zero. The voice alarm will stop if the patient's head angle value remains within the range for ≥4 seconds; otherwise, the reminder will continue.

[0060] In "Rest Mode", the initial value and alarm threshold of the angle monitor are set, and the "Rest Mode" is set. When patients cannot maintain a specific body position for a period of time while eating or bathing, or when patients with poor sleep quality cannot receive sound and vibration reminders at night and need a longer rest time, the reminder-free rest mode can be activated. The monitor still monitors the body position, but does not activate the sound and vibration reminder function, providing patients with a rest time.

[0061] As one embodiment of the present invention, the patient-side applet has functions such as real-time viewing of tilt angle data, learning health knowledge, communicating with doctors, and storing personal health records. It sets the initial value and operating status of the angle monitor through wireless communication and a human-computer interaction module. The web page acquires and analyzes the angle values ​​in real time to monitor body position information. Specific operation:

[0062] (1) Authorization Matters: ① After opening the WeChat mini program, users need to create a personal account for identity verification. However, only individuals on the user list submitted by specific organizations can pass the identity verification. ② After successfully creating an account, users must sign an online agreement authorizing relevant information, confidentiality, and risk management, and authorize information. After authorization, users must enter their personal information, such as health records, permanent address, and emergency contact information, and enable the phone's real-time microphone and voice functions.

[0063] (2) Function Introduction: ① Homepage: The homepage is the control interface, notification bar, and push notification bar of the angle monitor. Users can control the start and stop of the angle monitor recording and monitoring through this page before each rehabilitation activity begins; and at the same time, they can view the doctor's notifications and related knowledge push notifications after the rehabilitation activity ends. ② Discovery Page: The user settings page. Through this page, users can set the initial angle and warning angle values ​​of the angle monitor, and set the data transmission interval. During operation, the angle monitor will monitor the user's body position in real time and upload the angle data to the doctor's web platform according to the set transmission interval. If the user's body position angle exceeds the set warning angle threshold, the angle monitor will remind the patient to adjust the appropriate body position in time through the voice module and vibration module, and notify the nurse station in time through the nurse station call system. If the user fails to adjust the body position in time within a certain period of time, the nurse station staff will be notified to intervene in time to ensure the user's recovery effect. ③ Personal Homepage: Users can view the evaluation and status of each rehabilitation activity on the record page. The platform will analyze the proportion of the patient's warning time to the entire rehabilitation activity based on past cases in the database, and make an evaluation or warning.

[0064] As one embodiment of the present invention, the doctor-side web platform has functions such as contacting patients and their families, viewing tilt angle data in real time, and viewing the daily duty schedule. It acquires the patient's positional data in real time, and through cloud data analysis and processing, sends the data to the doctor's web interface. The doctor can view the patient's condition information in real time, provide timely feedback and adjustments, and formulate medical plans.

[0065] (1) Authorization Matters: ① After opening the platform, doctors need to enter personal information for identity verification. However, only those on the list of medical personnel submitted by specific units can pass the identity verification. ② After successfully creating an account, doctors need to select their personal identity, which is divided into medical personnel, patients, and family members. All three must submit identity verification documents. The platform will obtain the list of specific units and verify the identity documents before the corresponding identity can be verified. ③ Medical personnel who fail to be verified cannot view or understand the personal status of patients, nor can they receive any patient information.

[0066] (2) Function Introduction: ① Homepage: Lists each bound patient option. Clicking on a patient allows viewing their head tilt data, contact information, health records, and overall status. ② Retinal Pressure Analysis Page: By inputting parameters, the system uses physical modeling to analyze the distribution of air bubbles within the patient's eyeball, assisting doctors in adjusting the patient's position. ③ Posture Maintenance Analysis Page: This page allows doctors to view the patient's posture maintenance. The system analyzes past cases in the database to provide an evaluation of the patient and the possible time of deviation from the correct posture, providing doctors with reference for intervention. ④ Doctor Communication Page: Doctors can send notifications to patients and retrieve patient information through this page.

[0067] As one embodiment of the present invention, the intelligent call device realizes wireless data transmission through a WIFI module. When the system detects that the patient's head is shifted, it will issue an alarm and start timing. If the patient's head shift time exceeds the set time, it will obtain data such as the patient's room number, the direction and angle of head shift, and the shift time, and transmit the data to the administrator receiving end. If the patient cannot adjust his position within a certain period of time, the system will notify the nurse or family member to intervene and ensure the patient's recovery.

[0068] The embodiments of the present invention have the following advantages:

[0069] 1. Intelligent Rehabilitation Treatment: The complete post-retinal surgery auxiliary rehabilitation system solves the problem of doctors being unable to set personalized treatment plans based on the specific conditions of patients after retinal surgery, thus hindering efficient recovery. It also addresses the issue of patients being confined to bed due to generalized rehabilitation positions, which can lead to head displacement due to unintentional changes in posture during movement. With the system's assistance, doctors can use an eye bubble analysis device to pinpoint the relationship between intraocular bubbles and the lesion site of retinal detachment, determine appropriate rehabilitation positions, monitor patient status in real time, provide timely feedback and adjustments, and develop more suitable medical plans. Through the system, patients also understand the doctor's treatment plan, know their treatment progress, strengthen communication with doctors and nurses, and have more precise positioning angles, avoiding head displacement during activity and providing more space to reduce patient stress. Doctors, nurses, and family members can monitor patient status in real time, provide timely feedback and adjustments, and develop medical plans to help patients recover more scientifically and efficiently.

[0070] 2. Real-time angle monitoring and feedback: The angle monitor in the retinal surgery postoperative rehabilitation system has the functions of real-time angle monitoring, real-time data transmission, and real-time reminder feedback. It can monitor the patient's position in real time and remind the patient to maintain the correct position through a vibrator and voice system. The acquired data is transmitted to the patient's mini-program and the doctor's web platform in real time, and it also has an intelligent call function, which can better help the patient recover.

[0071] 3. "Rest Mode Setting": In "Rest Mode", the no-reminder rest mode can be activated. The monitor will still monitor the body position, but the sound and vibration reminder functions will not be activated, giving the patient a rest time.

[0072] 4. The voice and vibration alerts, as well as the precise setting of initial body position values ​​in the angle monitor, allow patients a greater range of motion, reduce the constraints of rehabilitation, and enable patients to correct their posture when problems occur, thereby improving patient compliance.

[0073] 5. Intelligent Integrated Platform Construction: The patient-side mini-program, doctor-side web platform, and intelligent call device form a comprehensive intelligent platform that facilitates effective collaboration and information sharing among doctors, nurses, and patients. Intelligent data analysis helps doctors better understand patients' daily recovery progress and develop personalized treatment plans based on their actual conditions. It also allows patients to understand their body position data, better track their recovery progress and process, and ensure effective recovery.

[0074] 6. Facilitates doctor and nurse supervision: The post-retinal surgery support system provides doctors and nurses with the ability to analyze and monitor patients' personal information via web pages or mini-programs, and offers necessary rehabilitation tips and answers to questions. This involvement of medical professionals can improve the quality of the rehabilitation process, help doctors and nurses obtain real-time patient positioning data, and intervene if the patient's position exceeds the warning value and is not adjusted in time, thus helping the patient recover better.

[0075] 7. Safe, efficient, fully functional, cost-effective, convenient and comfortable, easy for doctors, nurses and patients to use.
