Description

Technical Field

[0001] This invention relates to the technical field of visual rehabilitation training for amblyopia, specifically to a visual rehabilitation training device for amblyopia based on a dynamic visual model. Background Technology

[0002] This amblyopia visual rehabilitation training device based on a dynamic visual model adopts a modular design. It utilizes a deep learning dynamic visual model and the principle of visual neuroplasticity to conduct rehabilitation training. The device integrates pupil tracking, multiple types of sensors, and wireless data interaction modules, enabling real-time collection of data such as the user's eye movements and body status. Combined with training feedback, it dynamically adjusts parameters such as the target's movement speed, trajectory, contrast, and brightness. The device overcomes the limitations of traditional static training, allowing for customized rehabilitation plans based on different patients' visual conditions and training stages. Balancing scientific rigor and adaptability, it effectively activates visual nerves and improves binocular vision. Suitable for systematic rehabilitation training of various amblyopia populations, it is user-friendly and offers a superior user experience, effectively enhancing training compliance and overall rehabilitation outcomes.

[0003] Chinese patent CN218685165U discloses a vertical vision training and rehabilitation instrument, including a fixed box. A protrusion is fixedly connected to the upper surface of the fixed box. Connecting blocks are fixedly connected to the upper surfaces of the left and right sides of the protrusion via bolts. Telescopic rods are fixedly connected to the upper surfaces of both connecting blocks. The output ends of the two telescopic rods are jointly fixedly connected to the rehabilitation instrument. An adjustment mechanism is provided inside the fixed box. According to different heights, a rotating block rotates a worm gear, which in turn rotates a threaded rod, causing two moving ring blocks to move up and down. This, in turn, moves the two L-shaped fixed blocks up and down, adjusting the height of the rehabilitation instrument. This avoids the inconvenience caused by height adjustment for people of different heights during training and rehabilitation, improving the practicality of the equipment. Although this technical solution can be adjusted according to the user's height to meet the basic rehabilitation needs, the area around the user's eyes needs to be in contact with the support structure for a long time during training, which can easily cause muscle stiffness and discomfort. Especially in high-temperature environments, it can also cause heat accumulation and stuffiness, reducing the user experience. Summary of the Invention

[0005] This invention provides a visual rehabilitation training device for amblyopia based on a dynamic visual model. It has the following beneficial effects: 1. This amblyopia visual rehabilitation training device based on a dynamic visual model has an arc-shaped groove that can naturally conform to the facial contours of different users. It can be positioned without additional adjustments, and the fit is natural. It is suitable for different groups of people such as children and adults. The arc-shaped contact surface increases the contact range and avoids local single-point pressure, which reduces the feeling of pressure from a structural point of view. At the same time, it ensures the stability of the head posture, prevents the head from shifting during training, and ensures the accuracy of eye tracking and visual data acquisition.

[0006] 2. This amblyopia visual rehabilitation training device based on a dynamic visual model has a stop block that provides internal support to the support plate, enhancing the support plate's resistance to deformation. It will not dent or warp under long-term pressure and repeated activity. Multiple sets of contact axes simultaneously contact the area around the eyes, forming a continuous heat-conducting surface. The cold energy is evenly distributed, and the temperature difference in different areas around the eyes is small, avoiding local sudden changes in temperature.

[0007] 3. This amblyopia visual rehabilitation training device based on a dynamic visual model uses cold water flowing through a cooling pipe to remove heat from the cooling block, resulting in a stable cooling output. It avoids the problems of interruption and cooling attenuation that occur with traditional open-type water supply systems, meeting the continuous cold compress needs of children during long-term rehabilitation training. The cooling block is only connected to the contact parts and does not directly contact the human body. The cooling is indirectly conducted through the contact parts, forming a natural temperature buffer layer. This eliminates problems such as stinging, localized overcooling, and chilling caused by direct contact of the low temperature of the metal cooling block with the skin, thus improving user comfort.

[0008] 4. This amblyopia visual rehabilitation training device based on a dynamic visual model uses a snap-fit ​​connection structure for the contact frame, which can be quickly removed by medical staff or users. Through the fourth spring and sliding rod, the sliding block drives the cleaning roller to adaptively adjust the surface curvature and height difference of the observation window, ensuring that the roller fits the working surface throughout the process, cleaning without dead corners, wiping evenly, and improving the cleaning effect.

[0009] 5. This amblyopia visual rehabilitation training device based on a dynamic visual model has cleaning rollers installed on both sides simultaneously. With the help of moving blocks that slide in a straight line along the channel, it can completely cover the entire observation area. Compared with single-point cleaning, the cleaning coverage is larger, thoroughly removing dust, dander, and stains, ensuring the light path is transparent, and avoiding dirt from affecting visual training and eye movement data acquisition.

[0012] Please see Figures 1-2 This invention provides a visual rehabilitation training device for amblyopia based on a dynamic visual model, comprising: The top of the base 1 is fixedly connected to the adjustment frame 2, and the bottom of the rehabilitation host 3 is fixedly connected to the bottom of the adjustment frame 2. The adjustable frame 2 can be tilted so that the angle of the rehabilitation host 3 can be adjusted according to usage habits. The side of the rehabilitation host 3 is rotatably connected to a support component 4, and the side of the rehabilitation host 3 is fixedly connected to a contact component 5. The support component 4 can adjust the posture as needed, and the area around the eyes can be continuously cooled during long-term training to avoid local heat accumulation and discomfort. The contact component 5 also makes it easy to quickly clean the observation area when changing users. Example 1, please refer to Figure 3The invention also includes a support component 4. Both sides of the support frame 41 are rotatably connected to the inner side of the rehabilitation host 3. One end of the slide rod 42 is fixedly connected to the rotating plate 43, and the other end of the slide rod 42 is slidably connected to the inner side of the support frame 41. The side of the rotating plate 43 is rotatably connected to the inner side of the rehabilitation host 3. Rotating seats 44 are fixedly connected to both sides of the rotating plate 43. Rotating blocks 45 are symmetrically arranged on the inner side of the rehabilitation host 3. Both sides of the rotating blocks 45 are rotatably connected to the inner side of the rotating seats 44. When the device is in use, the rotating support frame 41 can drive the rotating plate 43 and the rotating seats 44 to move synchronously with the slide rod 42, so that the rotating seats 44 can complete the angle adjustment on the rotating blocks 45 on both sides of the host, thereby adapting to the facial features and usage habits of different users. A first spring 46 is fitted on the slide bar 42. One end of the first spring 46 is fixedly connected to the rotating plate 43, and the other end of the first spring 46 is fixedly connected to the support frame 41. A cooling mechanism 47 is fixedly connected to the inner side of the support frame 41. The support frame 41 and the rotating plate 43 are connected by the slide bar 42 and the first spring 46 fitted on the slide bar 42 to form a buffer connection, so that the support frame 41 can move slightly to relieve facial soreness caused by a fixed posture for a long time. During training, the cooling mechanism 47 can be activated to continuously cool the contact area around the user's eyes and avoid local heat accumulation and stuffiness and discomfort around the eyes caused by prolonged use. Please see Figures 4-5 It also includes a cooling mechanism 47, and an arc-shaped groove 472 is provided on the front of the support plate 471 and an arc-shaped groove 472 is provided on the side of the support plate 471, which can fit the contour around the human eye. A cooling block 475 is fixedly connected to the inner side of the support plate 471. A sliding shaft 476 is slidably connected to the inner side of the cooling block 475. A contact shaft 474 is fixedly connected to the inner side of the stop block 477. The side of the contact shaft 474 is slidably connected to the inner side of the support plate 471. The other end of the sliding shaft 476 is fixedly connected to the stop block 477. The side of the stop block 477 is in contact with the inner side of the support plate 471. The stop blocks 477 are evenly arranged on the inner side of the support plate 471 to provide support and ensure stable contact between the area around the eye and the arc groove 472. The stop block 477 and the cooling block 475 are connected by the sliding shaft 476. A second spring 478 is sleeved on the outer side of the shaft. A cooling water mechanism 473 is fixedly connected to the other side of the support plate 471. A second spring 478 is sleeved on the sliding shaft 476. One end of the second spring 478 is fixedly connected to the cooling block 475, and the other end of the second spring 478 is fixedly connected to the stop block 477. When a squeezing force is generated around the eye, the stop block 477 can achieve adaptive displacement with the help of the second spring 478 and the sliding shaft 476 to disperse the contact pressure and reduce the local pressure. A contact shaft 474 is fixed on the stop block 477. When the cooling water mechanism 47 is working, the contact shaft 474 contacts the area around the eye to achieve large-area uniform heat conduction and cooling. Please see Figure 6 It also includes a cooling water mechanism 473. Two cold water tanks 4731 are fixedly connected to both sides of the support plate 471. A cooling pipe 4733 is fixedly connected between the two cold water tanks 4731. The side of the cooling pipe 4733 is fixedly connected to the inside of the cooling block 475. Water pump 1 4732 and water pump 2 4734 are fixedly connected to both ends of the cooling pipe 4733. When the cooling function is activated, water pump 2 4734 in the cold water tank 4731 starts to run, continuously sending cold water into the cooling pipe 4733. The water flow eventually flows back to the other side of the cold water tank 4731, forming a closed-loop water circulation. The circulating water flow continuously cools the cooling block 475, and then cools the area around the user's eyes through heat conduction via the contact shaft 474, avoiding direct contact between the cooling block 475 and the head, and preventing discomfort caused by excessively low local temperature. Example 2, please refer to Figures 7-9 The invention also includes a contact component 5. Both sides of the contact frame 52 are snapped together with the inner side of the rehabilitation host 3. A slot 53 is provided in the middle of the side of the contact frame 52. After the equipment is used, if it is necessary to clean the observation window, the contact frame 52 can be removed from the inner side of the rehabilitation host 3 through the slot 53 on the side of the contact frame 52. A fourth spring 510 is fitted on the sliding rod 58. One end of the fourth spring 510 is fixedly connected to the moving block 59, and the other end of the fourth spring 510 is fixedly connected to the sliding block 57. Sliding blocks 57 are fixedly connected to both sides of the contact frame 52. A sliding rod 58 is fixedly connected to the middle of the side of the sliding block 57. The other end of the sliding rod 58 is slidably connected to the moving block 59. The side of the moving block 59 is slidably connected to the inner side of the slot 53. After the contact frame 52 is separated from the inner side of the rehabilitation host 3, the sliding block 57 is pushed by the reset of the fourth spring 510, so that the contact frame 52 drives the sliding block 57 to slide along the sliding rod 58, so that the sliding block 57 and the moving block 59 are separated from each other. The movable slots 51 are symmetrically arranged on both sides of the viewing port of the rehabilitation host 3. The side of the contact frame 52 away from the slot 53 is rotatably connected to the cleaning roller 56. The bottom of the movable block 59 is fixedly connected to the telescopic rod 54. The bottom of the telescopic rod 54 is fixedly connected to the inner side of the movable slot 51. A third spring 55 is sleeved on the telescopic rod 54. The top of the third spring 55 is fixedly connected to the movable block 59. The bottom of the third spring 55 is fixedly connected to the inner side of the slot 53. When the contact frame 52 is pressed down, the movable blocks 59 on both sides slide down along the movable slot 51, simultaneously squeezing the telescopic rod 54 and the third spring 55 sleeved on the telescopic rod 54, causing the cleaning roller 56 on the contact frame 52 to move down and fit against the surface of the viewing window. The cleaning operation is completed by the rolling of the cleaning roller 56. After cleaning, the third spring 55 elastically resets, pushing the telescopic rod 54 and the moving block 59 back to their initial positions; Finally, push the contact frame 52 back into the host to complete the reset assembly and ensure the normal use of the equipment in the future. Specific workflow: Once training begins, pupil tracking and eye movement sensors collect data such as eye rotation trajectory, fixation state, and fixation duration in real time, and record the entire training process synchronously. The dynamic visual model performs real-time calculations based on the monitoring information, adaptively adjusting the movement trajectory, movement speed, brightness contrast, color, and spatial position of the training visual target, and outputting dynamic visual stimuli that match the user's current visual level to accurately activate the visual nerves. During training, the device is equipped with voice and visual guidance to guide users in completing actions such as eye tracking, fixation, and binocular fusion, and to correct bad eye use and fixation habits in a timely manner to ensure that the training is carried out in a standardized manner. This machine is equipped with a tiltable adjustable frame 2, which can adjust the angle of the rehabilitation host 3 according to usage habits; The supporting component 4 can be adjusted as needed, and its eye-contact area can be kept cool during long-term training to avoid local heat accumulation and discomfort. It can also be used to quickly clean the observation area when changing users through the contact component 5. After a single group and the day's training, the system summarizes training data, task completion rate, action response accuracy, and other information. Combined with historical data, it comprehensively assesses the improvement of vision and visual function. The dynamic visual model automatically optimizes the training difficulty and parameters for the next stage based on the analysis results, updates the training plan, and continuously carries out closed-loop training to gradually repair and improve the visual function of amblyopic patients. When the device is in use, the rotating support frame 41 can drive the rotating plate 43 and the rotating seat 44 to move synchronously with the slide rod 42, so that the rotating seat 44 can be adjusted on the rotating blocks 45 on both sides of the main unit to adapt to the facial features and usage habits of different users. The support frame 41 and the rotating plate 43 are connected by a slide rod 42 and a first spring 46 sleeved on the slide rod 42 to form a buffer connection, so that the support frame 41 can move slightly to relieve facial soreness caused by a long time in a fixed posture. During training, the cooling mechanism 47 can be activated to continuously cool the contact area around the user's eyes and avoid local heat accumulation and stuffiness and discomfort around the eyes caused by long-term use. The support plate 471 has an arc-shaped groove 472 on its side, which can conform to the contour of the human eye area. The inner side of the support plate 471 is evenly provided with abutment blocks 477, which play a supporting role and ensure that the area around the eye is in stable contact with the arc-shaped groove 472. The abutment blocks 477 and the cooling block 475 are connected by a sliding shaft 476, and a second spring 478 is sleeved on the outside of the shaft. When a squeezing force is generated around the eye, the abutment blocks 477 can achieve adaptive displacement with the help of the spring and the sliding shaft 476, disperse the contact pressure, and reduce the local pressure. A contact shaft 474 is fixed on the abutment blocks 477. When the cold water cooling mechanism 47 is working, the contact shaft 474 contacts the area around the eye to achieve large-area uniform heat conduction and cooling. When the cooling function is activated, the second water pump 4734 in the cold water tank 4731 starts to run, continuously sending cold water into the cooling pipe 4733. The water flow eventually returns to the cold water tank 4731 on the other side, forming a closed-loop water circulation. The circulating water flow continuously cools the cooling block 475, and then cools the area around the user's eyes through heat conduction via the contact shaft 474, avoiding direct contact between the cooling block 475 and the head, and preventing discomfort caused by excessively low local temperature. After the equipment is used, if it is necessary to clean the observation window, the contact frame 52 can be removed from the inside of the rehabilitation host 3 through the slot 53 on the side of the contact frame 52. After the contact frame 52 is detached from the inside of the rehabilitation host 3, the sliding block 57 is pushed by the reset of the fourth spring 510, so that the contact frame 52 drives the sliding block 57 to slide along the sliding rod 58, so that the sliding block 57 and the moving block 59 are separated from each other. Press down on the contact frame 52, and the moving blocks 59 on both sides slide down along the moving groove 51, simultaneously squeezing the telescopic rod 54 and the third spring 55 sleeved on the telescopic rod 54, driving the cleaning roller 56 on the contact frame 52 to move down and fit against the surface of the observation window, and rely on the rolling of the cleaning roller 56 to complete the cleaning operation. After cleaning, the third spring 55 elastically resets, pushing the telescopic rod 54 and the moving block 59 back to their initial positions; Finally, push the contact frame 52 back into the main unit to complete the reset assembly and ensure normal operation of the equipment in the future.
