[0028] 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.

[0029] Example 1

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a retinal postoperative recovery device that facilitates adjustment of head tilt angle includes: a base 1, a head tray 11 disposed on top of the base 1, and a flexible support block 12 snapped onto the top of the head tray 11; a sliding frame 2 and several fixed cylinders 21 are disposed on the top of the base 1, several socket caps 22 are fixed to the bottom of the head tray 11, a movable block 3 is slidably connected to the inner side of the sliding frame 2, and a nose pad block 31 is retractably mounted on the top of the movable block 3; a tilt adjustment mechanism for adjusting the tilt angle of the head tray 11 relative to the placement plane is disposed on the base 1, and a first digital display level 4 is mounted on the top of the head tray 11; a control system for intelligently correcting the patient's head tilt posture is disposed inside the nose pad.

[0031] It should be noted that both the head tray 11 and the flexible support block 12 have a hollow structure in the middle to allow the patient's eyes, nose, and mouth to be suspended when tilting their head forward; the number of fixing cylinders 21 and connecting caps 22 is the same; the flexible support block 12 is made of high-elasticity memory foam to improve the flexibility of support for the patient; the top of the nose support block 31 has the highest degree of fit with the patient's nasal bone; when the placement surface of the base 1 is not horizontal, the tilt angle of the head tray 11 relative to the placement plane can be precisely adjusted through the tilt adjustment mechanism, and the first digital display level 4 on the top of the head tray 11 will adjust the level according to the angle change of the head tray 11. The system displays the headrest, ensuring that the adjusted headrest 11 achieves the ideal tilted-head position. When the patient faces the top of the flexible support block 12, the nose support block 31 at the top of the moving block 3 helps to fit and position the patient's nasal bone. With the help of the control system, the system can intelligently correct the patient's tilted-head posture. This ensures that the patient's head remains in a stable and appropriate ideal tilted-head position during recovery, especially when dealing with patients recovering from retinal surgery at different locations or when the head is not placed horizontally. This ensures the accuracy and effectiveness of postoperative positioning management, accelerates the patient's recovery process, and improves the postoperative recovery effect.

[0032] In this embodiment, the tilt adjustment mechanism includes: a plurality of first adjusting screws 5 threaded to the bottom of a plurality of fixed cylinders 21; the bottom of the plurality of first adjusting screws 5 is an arc-shaped structure to adapt to the inclination of the placement plane; the top of the fixed cylinder 21 is inserted into the inner side of the sleeve cap 22, and the bottom of the plurality of first adjusting screws 5 is located at the bottom of the chassis 1, and the number of first adjusting screws 5 and fixed cylinders 21 is the same.

[0033] It should be noted that when the device is placed on an inclined surface, the arc-shaped bottom of the first adjusting screw 5 can adapt to the inclination of the surface. By adjusting the screw depth of the first adjusting screw 5 at different positions, the levelness of the head tray 11 can be balanced. This allows for fine-tuning of the head tray 11 in both horizontal and vertical directions, meeting the individualized needs of different patients. It ensures that the head tray 11 can maintain an ideal tilted position regardless of the inclination of the device, thereby improving the quality and success rate of recovery and shortening the recovery period.

[0034] In this embodiment, a silicone pad 7 is installed on the top of the nose pad 31 to improve the patient's nasal bone contact comfort; the good elasticity and skin-friendly properties of the silicone pad 7 can further improve the patient's nasal bone contact comfort and reduce the discomfort caused by prolonged bending over.

[0035] In this embodiment, the control system includes: a plurality of pressure sensors 8 embedded between the top of the nose pad 31 and the silicone pad 7; a controller disposed inside the movable block 3 for setting pressure thresholds and issuing control signals; and a voice module disposed inside the movable block 3 for correcting and reminding the patient of incorrect postures; the controller is electrically connected to the pressure sensors 8 and the voice module respectively.

[0036] It should be noted that after the patient places their head on top of the head tray 11 and their nasal bone against the top of the nose pad 31, they activate three or more pressure sensors 8, maintain a correct head-down posture, and acquire the pressure value of the pressure sensors 8 under the current ideal head-down posture. The controller sets pressure thresholds X1, X2…Xn for different positions, such as 50g, 70g…40g, with thresholds of ±10g. While maintaining the head-down posture, the pressure sensors 8 transmit the real-time detected pressure value data to the controller. When the pressure value at a certain nasal bone feature point exceeds the set pressure threshold, the controller will control the voice module to provide a corresponding voice prompt based on the pressure value changes at different facial bone feature points. For example, if pressure threshold X1 is within the threshold, pressure threshold X2 exceeds +15g and is located on the left, and pressure threshold X3 exceeds -13g and is located on the right, the voice prompt will say: "Tilt to the left." This corrects the patient's incorrect posture, helping to ensure the patient maintains the correct posture when head-down and avoiding unnecessary pressure on the retina.

[0037] In this embodiment, the control system further includes: a data storage module installed inside the moving block 3 for storing pressure threshold change data; a Bluetooth module installed inside the moving block 3 for connecting the cloud database and hospital back-end data processing and management software with the control system; and an energy storage battery installed inside the moving block 3. The energy storage battery is electrically connected to the controller, pressure sensor 8, voice module, data storage module and Bluetooth module respectively. The cloud database and hospital back-end data processing and management software control the control system through the Bluetooth module.

[0038] It should be noted that the storage module and Bluetooth module are electrically connected, and both are electrically connected to the controller. The energy storage battery ensures the device can operate normally without an external power source, improving user convenience. The storage module stores data on changes in pressure thresholds due to patient posture. The cloud database, connected to the Bluetooth module, receives post-operative location data transmitted via Bluetooth and uploads it to the cloud database in real time. The cloud database connects to the app and the hospital management backend. The hospital management backend can adjust various parameters of the app through the cloud database API. Based on the database data, data trend charts can be displayed to analyze patient recovery progress and provide targeted medical reminders and follow-up examinations. Simultaneously, data is transmitted to the app via Bluetooth and saved in real time to the cloud database (the hospital management software can manage and configure the app through the cloud database). After the cloud database and hospital management software are interconnected, the hospital management software can maintain and manage medical and patient information, display data graphically, and send preset alarm values ​​to patients and their families. Medical staff can view any patient within the hospital and configure prompts and alarms to be sent to patients and their families via SMS. Furthermore, by storing and managing the data in the cloud, it facilitates later analysis by medical staff, allowing for convenient retrieval and use at any time. It also provides data support for handling medical disputes. Through hardware and software integration, it enables real-time monitoring and recording of patient positions. Patients can also monitor changes in position and recovery progress anytime, anywhere via mobile apps, computers, and other smart devices, providing a more convenient and efficient management tool that helps doctors better guide patients in postoperative recovery.

[0039] In this embodiment, a plurality of cards 10 are fixed to the top of the chassis 1, and a saliva tray 101 for collecting user saliva is snapped onto the inner side of the cards 10. A protruding structure 102 for easy handling is fixed to the side of the saliva tray 101. The cards 10 are fixed to the top of the chassis 1 to hold the saliva tray 101. The saliva tray 101 collects the saliva that may flow out when the patient bends over, keeping the device clean and hygienic. The protruding structure 102 on the side of the saliva tray 101 makes it easy for the patient or caregiver to pick up the saliva tray 101 for cleaning or replacement, improving the ease of use and convenience of the device.

[0040] The method of use in this embodiment involves using the tilt adjustment mechanism on the chassis 1, with the first adjusting screw 5 threaded to the bottom of the fixed cylinder 21. The screw's arc-shaped bottom adapts to the inclination of the placement surface, and the levelness of the head tray 11 is balanced by adjusting the screw depth, ensuring that the head tray 11 maintains an ideal tilted posture regardless of the surface it is placed on. The patient places their head on top of the head tray 11, with the eyes, nose, and mouth suspended by the perforated structure. The nasal bone rests against the silicone pad 7 on top of the nose support block 31, improving comfort. At this time, the control system is activated, and the pressure sensor 8 embedded in the nose support block 31 detects the pressure value of the nasal bone feature points in real time and compares it with the preset pressure threshold in the controller. If the pressure at a certain point exceeds the threshold, the controller will control the voice module to issue a voice reminder in the corresponding direction to correct the patient's incorrect posture. Simultaneously, the data storage module in the control system records the pressure threshold changes and uploads them to the cloud database via Bluetooth. The hospital's back-end management software can monitor patient data in real time, perform data analysis, display data trend charts, analyze the patient's recovery effect, and send targeted medical advice reminders and follow-up information to the patient and their family. In addition, the card slot 10 interface water tray 101 on the chassis 1 is used to collect saliva that may flow out when the patient bends over, keeping the equipment clean. The raised structure 102 on the side of the saliva tray 101 facilitates cleaning or replacement. Through intelligent and user-friendly design, the entire device ensures that the patient's head maintains a stable and suitable ideal bend over posture during the recovery process, accelerating the rehabilitation process and improving the recovery effect.

[0041] Example 2

[0042] like Figure 3 and Figure 4 As shown, this embodiment is basically the same as embodiment 1, except that:

[0043] The tilt adjustment mechanism includes: a plurality of second adjusting screws 6 threadedly connected to the top of a plurality of fixed cylinders 21; the top side of the plurality of second adjusting screws 6 is an arc-shaped structure, the top of the second adjusting screws 6 is inserted into the inner side of the socket cap 22, the number of second adjusting screws 6 and fixed cylinders 21 is the same; the outer diameter of the top of the second adjusting screw 6 is smaller than the inner diameter of the socket cap 22, so that there is a margin of movement inside the socket cap 22 when the top of the second adjusting screw 6 is tilted.

[0044] It should be noted that when the base plate 1 is placed on an inclined surface, the feed amount of the head tray 11 can be changed by rotating the second adjusting screw 6 at different positions. The top side of the second adjusting screw 6 is designed with an arc shape, which facilitates sliding within the socket cap 22 and adapts to different tilt angles. At the same time, the outer diameter of the top of the second adjusting screw 6 is smaller than the inner diameter of the socket cap 22, providing the necessary room for movement when tilting. This allows for fine-tuning of the head tray 11 in both horizontal and vertical directions, meeting the personalized needs of different patients. It ensures that the head tray 11 can maintain an ideal tilted position regardless of the inclination of the device, thereby improving recovery quality and success rate and shortening the recovery cycle.

[0045] The tilt adjustment mechanism also includes: a support block 61 fixed to the top of the chassis 1, a circular block 62 fixed to the bottom of the movable block 3, and several third adjusting screws 63 threadedly connected to the slide frame 2; the bottom of the circular block 62 is engaged with the top of the support block 61; the bottom of the several third adjusting screws 63 has an arc-shaped structure and contacts the top of the chassis 1; a second digital display level 64 is installed on the top of the slide frame 2.

[0046] It should be noted that the bottom of the circular block 62 is snapped into the top of the support block 61, ensuring the stability of the structure. The bottom of the third adjusting screw 63 is designed with an arc shape, which contacts the top of the chassis 1. By rotating the third adjusting screw 63 in different positions, its contact point with the chassis 1 can be changed, thereby adjusting the tilt angle of the nose pad 31. At the same time, the second digital display level 64 will display the changes in the angle of the nose pad 31 in real time, thus ensuring that the adjusted nose pad 31 reaches the same tilt angle as the head tray 11, thereby ensuring the patient's comfort and the accuracy of the intelligent monitoring of the control system.

[0047] Example 3

[0048] like Figure 5 As shown, this embodiment is basically the same as embodiment 1, except that:

[0049] The side of the movable block 3 is provided with a positioning component, which includes: a positioning groove 9 opened on the side of the slide frame 2, and a plurality of positioning screws 91 provided on the side of the slide frame 2 and the movable block 3; the side of the positioning screw 91 on the side of the slide frame 2 is located inside the positioning groove 9, and one end is threadedly connected to the side of the movable block 3; the side of the positioning screw 91 on the side of the movable block 3 is threadedly connected to the inner side of the movable block 3, and one end abuts against the side of the nose pad block 31.

[0050] It should be noted that when the moving block 3 is pushed to slide within the sliding frame 2 until it reaches the appropriate position relative to the patient's nasal bone, the positioning screw 91 on the side of the sliding frame 2 is rotated to securely lock the moving block 3 in its current position within the sliding frame 2. This enables precise positioning and locking relative to the patient's nasal bone. At the same time, after the nasal pad 31 is adjusted to the appropriate position, another set of positioning screws 91 on the side of the moving block 3 can securely lock the nasal pad 31 in its current position at the top of the moving block 3, thus achieving locking at the appropriate support position.

[0051] 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.
