[0020] (1) This utility model provides a portable posture monitoring device based on retinal surgery. The main structure is composed of an arc-shaped ear loop and a contact box, and the posture monitoring system is integrated into the internal monitoring box, achieving a high degree of integration and portability. This can greatly improve the stability and comfort of the patient when wearing it. It not only effectively overcomes the defects of traditional posture maintenance devices such as bulkiness, inconvenience and lack of real-time monitoring, but also significantly enhances the patient's compliance with medical orders, ensures the accuracy and effectiveness of postoperative posture management, thereby accelerating the patient's recovery process and improving the overall treatment effect.

[0021] (2) In this utility model, by setting a self-starting component inside the contact box, when the patient wears the device, the patient rotates the rotating bar according to the left or right ear to be worn.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown, a portable posture monitoring device based on retinal surgery includes: a contact box 1, a rotating bar 2 disposed inside the contact box 1, and an arc-shaped ear hook 21 fixed to one end of the rotating bar 2 at the top of the contact box 1 for hanging on either the left or right ear of the patient; a monitoring box 3 is installed inside the contact box 1, and a posture monitoring system is disposed inside the monitoring box 3, the posture monitoring system including: a controller disposed inside the monitoring box 3 for setting tilt angle thresholds and issuing control signals, an angle sensor for detecting the horizontal angle of the patient wearing the device, and a voice module for reminding the patient of incorrect posture; a limiting component is disposed on the side of the rotating bar 2 located inside the contact box 1 for limiting the rotation direction of the rotating bar 2; and a self-starting component is disposed inside the contact box 1 for sending a start signal to the controller when the arc-shaped ear hook 21 changes its horizontal state relative to the contact box 1.

[0033] It should be noted that the side of the rotating bar 2 near the top is rotatably connected to the top of the contact box 1, which is used to adjust the wearing angle between the arc-shaped ear hook 21 and the contact box 1. The wearing angle is 5-100°, preferably 20°. The controller is electrically connected to the angle sensor and the voice module respectively. Before wearing, the patient sets the floating threshold for the tilt angle change during the head-down posture maintenance process through the controller in the posture monitoring system, such as -5 degrees to 5 degrees. After the patient enters the correct retinal surgery and recovers the head-down posture, the arc-shaped ear hook 21 is rotated according to the left or right ear to make the wearing angle between the arc-shaped ear hook 21 and the contact box 1 in the corresponding direction. The rotation direction is limited by the cooperation of the limiting component, and the arc-shaped ear hook 21 is hung on the patient's ear. After one side of the contact box 1 contacts the patient's ear, the posture monitoring system is turned on, and the angle sensor... The device uses the current posture as the initial angle and detects the change in tilt angle in real time during the head-down posture maintenance. When the angle value exceeds the set floating threshold, the controller will control the voice module to provide voice reminders for head-down posture maintenance, thereby correcting the patient's incorrect posture. This helps ensure that the patient maintains the correct posture when bending over, avoiding unnecessary pressure on the retina. Furthermore, the posture monitoring system is integrated into the internal monitoring box 3 through the main structure consisting of an arc-shaped ear loop 21 and a contact box 1, achieving a high degree of integration and portability. This greatly improves the stability and comfort of the patient's wearing experience. It not only effectively overcomes the shortcomings of traditional posture maintenance devices such as bulkiness, inconvenience, and lack of real-time monitoring, but also significantly enhances the patient's compliance with medical advice, ensuring the accuracy and effectiveness of postoperative posture management, thereby accelerating the patient's recovery process and improving the overall treatment effect.

[0034] like Figure 2 and Figure 3 As shown, in this embodiment, the self-starting component includes: a control switch 4 fixed to the bottom of the inner side of the contact box 1, a convex button 41 retractably installed on one side of the control switch 4 for triggering the control switch 4 to open, and a concave groove 42 formed on the side of the rotating bar 2; a number of indicator lights 43 for displaying the working status are installed on one side of the contact box 1, the cross-sectional shape of the rotating bar 2 is circular, one end of the convex button 41 is inserted into the inner side of the concave groove 42, and the control switch 4 is electrically connected to the controller and the indicator lights 43 respectively.

[0035] It should be noted that during the wearing process, when the patient rotates the rotating strip 2 according to the desired left or right ear, the convex button 41 on the control switch 4, initially inserted into the concave groove 42, is gradually disengaged from the interior of the concave groove 42 by the pressure of the rotating strip 2, and comes into contact with the inclined surface of the concave groove 42 or the side of the rotating strip 2. This causes the convex button 41 to extend into the control switch 4 and trigger, sending a start signal to the controller. At the same time, the indicator light 43 illuminates to indicate the working status, ensuring that the posture monitoring system can automatically start after the patient wears the device correctly and begin real-time monitoring of the patient's posture, thereby improving the intelligence of the wearing process.

[0036] like Figure 2 As shown, in this embodiment, the limiting component includes: a sleeve 6 sleeved on the side of the rotating bar 2, a limiting ring 61 fixed on the side of the rotating bar 2, and a limiting groove 62 formed on the side of the rotating bar 2; the side of the limiting ring 61 is engaged with the inner side of the sleeve 6, and the side of the contact box 1 is threadedly connected to a limiting screw 63, one end of the limiting screw 63 passing through the sleeve 6 and located inside the limiting groove 62; the top of the sleeve 6 is fixed to the top of the inner side of the contact box 1.

[0037] It should be noted that both the sleeve 6 and the limiting ring 61 are coaxially arranged with the rotating bar 2. When the rotating bar 2 rotates inside the sleeve 6, the limiting ring 61 on the side of the rotating bar 2 can rotate inside the sleeve 6, which plays a role in stabilizing and limiting the rotation. When the rotating bar 2 rotates to a certain position, the limiting groove 62 on the side of the rotating bar 2 will be resisted by the limiting screw 63, thereby limiting the further rotation of the rotating bar 2. This ensures that the wearing angle between the arc-shaped hanging ear strip 21 and the contact box 1 is kept within the set range, improving the controllability and operability of the device.

[0038] In this embodiment, the inner side of the sleeve 6 is provided with an elastic reset component for automatically resetting the initial position after the rotating bar 2 rotates; the elastic reset component includes: an elastic steel wire 7 passing through the sleeve 6 and the rotating bar 2, and a tower spring 71 disposed on the side of the rotating bar 2; one end of the elastic steel wire 7 is fixed to the inner side of the contact box 1, the top end of the tower spring 71 is fixed to the side of the rotating bar 2, and the bottom end is fixed to the inner side of the contact box 1.

[0039] It should be noted that after the patient completes the adjustment of the wearing angle between the arc-shaped ear loop 21 and the contact box 1 and wears it on the ear, the elastic steel wire 7 passing through the sleeve 6 and the rotating bar 2 and the tower spring 71 on the side of the rotating bar 2 can work together to act on the rotating bar 2. Under the limitation of the rotating bar 2 and the ear, the contact box 1 can be subjected to a slight rotational force, which improves the fit between the contact box 1 and the patient's ear. At the same time, after the external force is applied when the ear is removed, the rotating bar 2 can automatically return to the initial position, further allowing the convex button 41 to extend into the concave groove 42, automatically turning off the start state, thereby improving the stability and reliability of the device.

[0040] In this embodiment, the posture monitoring system further includes: a data storage module, a Bluetooth module, and a bone conduction headset disposed inside the monitoring box 3; the data storage module and the Bluetooth module are electrically connected to the controller, and the bone conduction headset is electrically connected to the voice module; the data storage module is used to store angle threshold change data; the Bluetooth module is used to connect the cloud database and the hospital's back-end data processing and management software to the posture monitoring system, and the cloud database and the hospital's back-end data processing and management software control the posture monitoring system through the Bluetooth module; the bone conduction headset is used to convert signals into vibrations to achieve the perception of reminder sounds for the patient.

[0041] It should be noted that the bone conduction headphones specifically convert sound signals into mechanical vibrations of different frequencies to achieve the perception of reminder sounds. These are standard components or parts known to those skilled in the art; their structure and principles are readily understood by those skilled in the art through technical manuals or conventional experimental methods, and will not be elaborated upon here. By receiving reminder signals from the voice module through the bone conduction headphones and converting these signals into vibrations transmitted to the patient, the patient can clearly perceive the reminder sounds even in noisy environments. This not only improves the intelligence level of the device but also enhances the convenience and comfort of patient use. The data storage module can store data on changes in the patient's horizontal angle threshold due to posture changes. The cloud database, connected to the Bluetooth module, can receive postoperative position data transmitted by the patient via Bluetooth and upload this data to the cloud database in real time for storage. The cloud database is linked to the APP and the backend hospital management terminal. The backend hospital management terminal can configure various parameters of the APP through the cloud database API. Based on the database data, data trend charts can be displayed, allowing analysis of the patient's recovery effect and providing targeted medical reminders and follow-up examinations. Simultaneously, data is transmitted to the APP via Bluetooth and then stored in a cloud database in real time (the hospital's back-end management software can manage and configure the APP through the cloud database). After the cloud database and the hospital's back-end management software are interconnected, the latter can maintain and manage medical and patient information, display data graphically, and send preset alarm values ​​to patients and their families. Medical and nursing staff can view any patient within the hospital and configure prompts and alarms, which are sent to patients and their families via SMS. Furthermore, by storing and managing data in the cloud, it facilitates later analysis by medical staff, allows for convenient retrieval and use, provides data support for medical disputes, and enables real-time monitoring and recording of patient positions through hardware and software integration. Patients can also monitor changes in position and recovery progress anytime, anywhere via mobile APP, computer, and other smart devices, providing a more convenient and efficient management method and helping doctors better guide patients in postoperative recovery.

[0042] In this embodiment, the monitoring box 3 is equipped with an energy storage battery, which is electrically connected to the controller, angle sensor, voice module, data storage module, Bluetooth module and bone conduction earphone. The energy storage battery ensures that the device can work normally without an external power source, improving the convenience of use for patients.

[0043] In this embodiment, the material of the arc-shaped ear loop 21 is either silicone or rubber. By making the material of the arc-shaped ear loop 21 a flexible material such as silicone or rubber, the flexibility during wearing can be guaranteed and the comfort of the patient can be improved.

[0044] In this embodiment, the patient first adjusts the wearing angle between the curved ear loop 21 and the contact box 1 by rotating it according to the desired left or right ear. The concave groove 42 on the side of the rotating strip 2 presses against the convex button 41 on the control switch 4, causing it to gradually disengage from the concave groove 42 and triggering the control switch 4. This sends a start signal to the controller, activating the posture monitoring system. The posture monitoring system monitors the changes in the horizontal angle of the patient in real time using an angle sensor and compares the data with a preset tilt angle threshold. Once the threshold is exceeded, the controller controls the voice module to transmit a reminder signal to the patient via bone conduction headphones, correcting the incorrect posture. Simultaneously, the sleeve 6, limit post 61, and limit groove 62 in the limiting assembly ensure that the rotating strip 2 can be stably limited after rotating to the set position, preventing further rotation. The elastic reset assembly allows the rotating strip 2 to automatically return to its initial position after wearing and automatically shuts off the start state when it is removed. In addition, the data storage module records angle change data, and the Bluetooth module enables connection with the cloud database and hospital backend, facilitating remote monitoring and analysis of the patient's recovery effect by medical staff. The entire system is powered by a storage battery, ensuring normal operation even without an external power source. This greatly improves the stability and comfort of the patient's wear, and helps ensure the accuracy and effectiveness of postoperative positioning management.

[0045] Example 2

[0046] like Figure 4 As shown, this embodiment is basically the same as embodiment 1, except that: the self-starting component includes: a pressure sensor 5 fixed inside the contact box 1; the cross-sectional shape of the rotating bar 2 is elliptical, the side of the pressure sensor 5 is in contact with the side of the rotating bar 2, and the pressure sensor 5 is electrically connected to the controller; the major axis of the rotating bar 2 is horizontal to the pressure sensor 5, and the minor axis is vertical to the pressure sensor 5.

[0047] It should be noted that during the wearing process, when the patient rotates the rotating strip 2 according to the desired left or right ear, the pressure sensor 5 is fixed inside the contact box 1 and its side contacts the side of the rotating strip 2. The elliptical cross-sectional shape of the rotating strip 2 will gradually cause the two ends in the long axis direction to press against the part in contact with the pressure sensor 5 under the action of the rotation angle. This will cause the pressure value received by the pressure sensor 5 to change, thereby triggering the pressure sensor 5 to send a start signal to the controller. This ensures that after the patient wears the device correctly, the posture monitoring system can automatically start and begin to monitor the patient's posture in real time, thereby improving the intelligence of the wearing process.

[0048] Based on the above description and the preferred embodiments of this utility model, it will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model.
