Description

Technical Field

[0001] This invention relates to the field of ophthalmic care technology, specifically to an amblyopia physiotherapy and rehabilitation device for ophthalmic care. Background Technology

[0002] Amblyopia is a common condition in childhood development. It refers to a condition where no organic lesions are found inside or outside the eye during examination, but vision cannot be corrected to a normal visual state. Training the eye's ability to rotate inward and outward exercises the eye muscles, causing continuous movement of the visual axes of both eyes to train the three muscles that control vision—the ciliary muscle, extraocular muscles, and iris muscle. Amblyopia training devices can have a significant effect on improving the vision of children with amblyopia.

[0003] One existing home-use amblyopia training device features light brush training, red flash training, and visual stimulation training. Visual stimulation training typically uses a black and white striped stimulus source with a transparent background containing a graphic above it. Children must trace the outline of the graphic on the transparent background while the stimulus source rotates. The principle behind visual stimulation is to break the inhibitory state of the visual center through specific visual stimulation, promoting the development of photoreceptor cells and neural pathways, ultimately improving vision in the amblyopic eye. However, in this amblyopia training device, the black and white striped stimulus source is constantly lit, which can easily cause children's visual system to be in a high-intensity working state for a long time without rest and buffer, easily leading to fatigue and potentially additional visual burden. Furthermore, the visual center of the child's brain gradually adapts to fixed stimuli, causing the training effect of the constantly lit stimulus source to decline over time, even leading to ineffective training. Summary of the Invention

[0004] The purpose of this invention is to provide an amblyopia physiotherapy and rehabilitation device for ophthalmic care, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an amblyopia physiotherapy and rehabilitation device for ophthalmic care, comprising a main control panel and a light brush and training glasses connected to one side of the main control panel via wires. A groove is formed at one end of the top of the main control panel, and a transparent plate is disposed inside the groove. Multiple evenly distributed black baffles are fixedly installed on the top of the transparent plate, and a light column is fixedly installed on the bottom of the transparent plate. A rotating seat is rotatably mounted inside the main control panel, and the light column is fixedly installed on the top of the rotating seat. A rotating mechanism is disposed outside the rotating seat, and a frame is fixedly installed on the top of the rotating seat. A movable frame is slidably mounted inside the frame, and multiple evenly distributed black baffles are fixedly installed inside the movable frame. A gap adjustment mechanism and an intermittent blocking mechanism are disposed inside the rotating seat, and a graphic drawing mechanism is disposed above the groove.

[0006] Preferably, both ends of the frame are provided with sliding grooves, and both ends of the movable frame are slidably installed inside the two sliding grooves respectively.

[0007] Preferably, the rotating mechanism includes a first transmission gear, a second transmission gear, and a first motor. The first transmission gear is fixedly sleeved on the outside of the rotating seat, and the first transmission gear and the second transmission gear mesh with each other. The output shaft end of the first motor is fixedly connected to the second transmission gear, and the first motor is fixedly installed inside the main control panel.

[0008] Preferably, the gap adjustment mechanism includes a rotating disk and an operating component. A connecting rod is fixedly installed at one end of the top of the rotating disk. A sliding rod is fixedly installed at the top of the connecting rod. A connecting rod is slidably sleeved on the outside of the top of the sliding rod. A spring is sleeved on the outside of the bottom of the sliding rod. An adjusting rod is rotatably installed on one side of the top of the connecting rod. The end of the adjusting rod away from the connecting rod is rotatably connected to the bottom of the movable frame. Both the connecting rod and the connecting rod are slidably fitted inside the rotating seat.

[0009] Preferably, the operating component includes a threaded rod and a guide rod 1. The threaded rod is rotatably mounted inside the main control panel. Both sides of the guide rod 1 are fixedly connected to the inner wall of the main control panel. An adjusting plate is threadedly connected to the outside of the threaded rod. The end of the adjusting plate away from the threaded rod is slidably sleeved on the outside of the guide rod 1. A transmission rod is rotatably mounted on the top of the adjusting plate. A fixed disk is rotatably mounted on the top of the transmission rod. The rotating disk is rotatably mounted on the top of the fixed disk. Guide rod 2 is slidably sleeved on both ends of the fixed disk. The bottoms of the two guide rod 2 are fixedly connected to the inner wall of the main control panel.

[0010] Preferably, the intermittent blocking mechanism includes a second motor and a transmission plate. A transmission cam is fixedly installed on the output shaft end of the second motor. One end of the transmission plate is fixedly connected to a second connecting rod. Guide rods three are slidably sleeved on both ends of the transmission plate. The second motor and the two guide rods three are fixedly installed inside the main control panel. A fixing plate is slidably sleeved on the top ends of the two guide rods three. Springs two are fixedly installed on both ends of the bottom of the fixing plate. The two springs two are respectively sleeved on the outside of the two guide rods three.

[0012] Preferably, three switch buttons are fixedly installed on one side of the main control panel, and the three switch buttons are electrically connected to the light column, motor one and motor two, respectively.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By setting an intermittent blocking mechanism, the stimulation source of the device creates an intermittent light transmission effect. Compared with the existing technology, the stimulation source is no longer in a constant state of light, which reduces children's eye fatigue. By alternating between light and dark, it avoids the adaptation of children's visual nerves, keeps the stimulation effective, and makes it easier to overcome the inhibition of amblyopia. At the same time, the sense of change brought about by the temporary blocking of the stimulation source can improve children's attention during training and reduce resistance.

[0015] 2. The gap adjustment mechanism allows for adjustment of the light-transmitting gaps between multiple black strips. The density of the stripes can be adapted to the child's visual level. When the child's vision is poor, the gaps between the multiple black strips are wider to make it easier for the child to see clearly. As the child's vision improves, the gaps between the multiple black strips can be narrowed to appropriately increase the difficulty of visual stimulation training. At the same time, it can also avoid the child's eyes becoming fatigued due to excessively strong stimuli, or the child's eyes not being effectively trained for amblyopia due to excessively weak stimuli.

A top rod 38 is fixedly installed in the middle of the fixing plate 32. The top and bottom of the top rod 38 cooperate with the transmission cam 29 and the transmission plate 30, respectively.

[0036] The graphic drawing mechanism includes a transparent cover 34, which cooperates with the top of the groove 4. The top of the transparent cover 34 has a placement groove 35, and a graphic film 36 is placed inside the placement groove 35.

[0037] Three switch buttons 37 are fixedly installed on one side of the main control panel 1. The three switch buttons 37 are electrically connected to the light column 7, motor 15 and motor 28 respectively.

[0038] Working principle: When in use, parents control the light brush device 2 or training glasses 3 through the main control panel 1 to conduct light brush training or red flash training for children with amblyopia. The light brush training and red flash training in this device are existing technologies and will not be described in detail here. When conducting visual stimulation training for children, first insert the graphic film 36 into the placement slot 35, turn on the switch button 37 corresponding to the light column 7, the light column 7 lights up and transmits light to the transparent plate 5, which works in conjunction with multiple black baffles 6 to form a black and white stripe stimulation source. Then start the motor 15, which drives the transmission gear 14 connected to it to rotate. Under the action of the transmission gear 14 meshing with the transmission gear 13, the transmission gear 13 drives the rotating seat 8 to rotate. At this time, the child traces the outline of the graphic film 36 on the top of the transparent cover 34, and then conducts visual stimulation training. This device has a significant effect on the rehabilitation of children with amblyopia through light brush training, red flash training and visual stimulation training.

[0039] The gap adjustment mechanism allows for adjustment of the light transmission gap between multiple black baffles 6 according to the degree of amblyopia in children. A larger gap between the baffles 6 results in a wider light transmission gap. To adjust this gap, first rotate the threaded rod 22. Simultaneously, under the action of the guide rod 23, the adjusting plate 24 moves along the threaded rod 22. As the adjusting plate 24 moves, it also drives the bottom end of the transmission rod 25 to move synchronously, thereby causing the fixed plate 26 to move downwards. The fixed plate 26 slides steadily downwards along the two guide rods 27. The rotating plate 16, connecting rod 17, and connecting rod 19 all move downwards. At this time, the spring 20 will not deform. As the connecting rod 19 moves downwards, the adjusting rod 21 pulls the moving frame 10 along the two sliding grooves 12. The sliding and moving frame 10 drives multiple black baffles 11 to move synchronously. The multiple black baffles 11 block the light-transmitting gap between two adjacent black baffles 6, thereby reducing the light-transmitting gap between the multiple black baffles 6. After adjusting to the appropriate position, the rotation of the threaded rod 22 is stopped. By adjusting the light-transmitting gap between the multiple black baffles 6, the density of the stripes can be adapted to the child's visual level. When the child's vision is poor, the light-transmitting gap between the multiple black baffles 6 is wider, making it easier for the child to see clearly. After the vision improves, the light-transmitting gap between the multiple black baffles 6 can be narrowed to appropriately increase the difficulty of visual stimulation training. At the same time, it can also avoid the stimulus source being too strong, causing eye fatigue in children, or the stimulus source being too weak, causing the stimulus source to be unable to effectively produce the effect of visual stimulation training for children with amblyopia.

[0040] By turning on the switch button 37 corresponding to motor 28, motor 28 is activated, driving the transmission cam 29 to rotate. During the rotation of the transmission cam 29, when its protruding part acts on the push rod 38, the push rod 38 is forced to move the fixed plate 32 downward. The fixed plate 32 slides steadily downward along the two guide rods 31, and the two springs 23 are compressed simultaneously. As the push rod 38 moves downward, it acts on the transmission plate 30 at its bottom. The two ends of the transmission plate 30 slide steadily downward along the two guide rods 31. As the transmission plate 30 moves downward, it drives the connecting rod 219 to move downward to its lowest limit position. At this time, the spring 120 is compressed, and the adjusting rod 21 also moves to its limit position, thereby pulling the moving frame 10 and multiple black stop bars 211 to their limit positions. The colored baffle 11 completely blocks the light-transmitting gaps between the multiple black baffles 6, thus preventing light transmission. As the transmission cam 29 continues to rotate, when the protruding part of the transmission cam 29 is misaligned with the push rod 38, the push rod 38 moves upward and resets under the action of the two springs 33. The connecting rod 19, the moving frame 10, and the multiple black baffles 11 are reset to their adjusted positions under the action of the spring 20. This process is repeated to create an intermittent light transmission effect. Compared with existing technologies, the stimulus source is no longer in a constantly lit state, reducing eye fatigue in children. By alternating between light and dark, it avoids adaptation of children's visual nerves, keeping the stimulus effective and making it easier to overcome the inhibition of amblyopia. At the same time, it can also avoid the stimulus source being too strong, causing eye fatigue in children, or the stimulus source being too weak, making it impossible to effectively train children's amblyopia.
