Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary training device for strabismus and amblyopia correction. Background Technology

[0002] Strabismus refers to the inability of both eyes to fixate on a target simultaneously. It is an extraocular muscle disorder. Studies have shown a significant correlation between strabismus and amblyopia. Strabismus is a major contributing factor to amblyopia, and more than half of amblyopia cases are related to strabismus. In terms of symptoms, strabismus is an abnormality of eye position, while amblyopia is an abnormality of vision. Clinical practice shows that targeted treatment can lead to good prognoses for children with strabismus and amblyopia.

[0003] Chinese Patent Publication No. CN211188132U discloses a pediatric strabismus auxiliary correction device. Addressing the shortcomings of existing strabismus auxiliary correction methods, where the rocker arm for adjusting the movement of two colored balls is located at the child's face when the child is looking directly at them, this method is inconvenient, easily attracts the child's attention, and affects the correction effect. Furthermore, the colored balls cannot be fixed in place for static treatment. The proposed solution includes a base with an arc-shaped opening fixedly mounted on its top side. An adjustment cavity is formed on the base, and a mounting hole is formed on the inner wall of the top side of the adjustment cavity. Two rocker arms are rotatably mounted within the mounting hole.

[0004] This device controls two colored balls to move closer or further apart by manually rotating a knob, and repeated training is used to correct strabismus. However, rotating the knob for a long time is labor-intensive and can also affect the patient's attention. Therefore, we propose an auxiliary training device for strabismus and amblyopia correction to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides an auxiliary training device for strabismus and amblyopia correction, including two parallel support plates 1. The tops of the two support plates 1 are rotatably connected to rotating shafts 3. The rotating shafts 3 are fixedly connected to both ends of guide columns 2. The guide columns 2 are slidably sleeved with sliding frames 6. A transmission component 7 is fixedly connected to one side of the outer wall of the sliding frame 6. A servo motor 10 is fixedly installed in the middle of one end face of the transmission component 7. The transmission component 7 is fixedly connected to one end of a support column 8. The other end of the support column 8 is fixedly connected to a colored ball 9. The other side of the outer wall of the sliding frame 6 is fixedly connected to one end of a connecting column 11. The other end of the connecting column 11 is fixedly connected to a display screen 12.

[0020] A support plate 1 has sliding rods 13 on both sides of its top, and a support plate 15 is fixedly connected to the top of the sliding rods 13.

[0021] The user's chin is supported by the support plate 15, improving user comfort. The sliding frame 6 is moved according to the user's vision. Once the sliding frame 6 is adjusted to a suitable position and stops, the servo motor 10 is powered on, driving the transmission component 7. The transmission component 7 drives the colored ball 9 to move back and forth in a linear motion. The user's eyes are focused on the colored ball 9, and their eyes follow the movement of the colored ball 9, achieving strabismus correction training. When amblyopia correction training is needed, the positioning thread knob 5 is manually loosened. The end of the positioning thread knob 5 disengages from the support plate 1, allowing the guide column 2 to rotate. After the guide column 2 rotates 180 degrees, the display screen 12 is positioned above. Then, the positioning thread knob 5 is tightened, and it contacts the outer wall of the support plate 1. Friction fixes the angle of the guide column 2. The display screen 12 is connected to the computer and power supply, displaying amblyopia correction images for amblyopia correction training.

[0022] Example 2

[0023] Reference Figure 1-2This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, one end of a rotating shaft 3 is fixedly connected to one end of a connecting rod 4, and the other end of the connecting rod 4 is connected to a positioning threaded knob 5 through a threaded structure. The end of the positioning threaded knob 5 abuts against the support plate 1. When amblyopia correction training is required, the positioning threaded knob 5 is manually loosened, and the end of the positioning threaded knob 5 is disengaged from the support plate 1, thereby allowing the guide column 2 to rotate. After the guide column 2 rotates 180 degrees, the display screen 12 is positioned above. Then, the positioning threaded knob 5 is tightened, and the positioning threaded knob 5 abuts against the outer wall of the support plate 1, and the angle of the guide column 2 is fixed by friction.

[0024] Specifically, the top of the tray 15 has an arc-shaped groove, and a sponge is fixedly installed in the arc-shaped groove to improve the comfort of the user's chin contact.

[0025] Specifically, a support plate 1 has two sides of one end face connected by a threaded structure with positioning bolts 14. The ends of the positioning bolts 14 abut against the outer wall of the slide rod 13. Depending on the height of the user, the positioning bolts 14 can be manually loosened so that the ends of the positioning bolts 14 are disengaged from the abutting connection of the slide rod 13, thereby adjusting the height of the support plate 15. After the height of the support plate 15 is adjusted, the positioning bolts 14 are manually tightened again. The ends of the positioning bolts 14 abut against the outer wall of the slide rod 13, thereby fixing and limiting the position of the slide rod 13 through friction, keeping the height of the support plate 15 fixed.

[0026] Specifically, the transmission assembly 7 includes a support base 71, a slide groove 72, a movable plate 73, a rack 74, a half-tooth gear 75, and a movable cavity 76. One end of the support base 71 is fixedly connected to the slide frame 6, and the other end of the support base 71 is recessed with a slide groove 72. The movable plate 73 is slidably engaged in the slide groove 72. The movable plate 73 has a movable cavity 76. The inner walls of both sides of the movable cavity 76 are fixedly connected to racks 74 respectively. One side of the rack 74 meshes with the half-tooth gear 75. The half-tooth gear 75 is rotatably disposed in the movable cavity 76 and is fixedly connected to the output shaft of the servo motor 10.

[0027] Furthermore, the movable cavity 76 has a racetrack-shaped structure, with the rack and pinion 74 positioned opposite each other. When the servo motor 10 is powered on, it drives the transmission assembly 7 to work, causing the half-tooth gear 75 to rotate in a circular motion. The rotating half-tooth gear 75, in conjunction with the rack and pinion 74, drives the movable plate 73 to reciprocate linearly within the slide groove 72. The movable plate 73 is fixedly connected to the support column 8, which in turn drives the colored ball 9 to reciprocate linearly. The user's eyes are focused directly on the colored ball 9, and their eyes follow the movement and rotation of the colored ball 9, thus achieving strabismus correction training.

[0028] Example 3

[0029] Reference Figure 1-2This is the third embodiment of the present invention. Based on the previous two embodiments, in use, the user's chin is supported by the support plate 15, improving user comfort. Simultaneously, depending on the user's height, the positioning bolt 14 can be manually loosened, disengaging its end from the sliding rod 13, thus allowing adjustment of the support plate 15's height. After height adjustment, the positioning bolt 14 is manually tightened again, with its end abutting against the outer wall of the sliding rod 13, thereby fixing the position of the sliding rod 13 through friction, maintaining a fixed height for the support plate 15. Depending on the user's vision, the sliding frame 6 is moved. Once adjusted to a suitable position, the sliding frame 6 stops, and the servo motor 10 is powered on, driving the transmission assembly 7, causing the half-tooth gear 75 to rotate. The rotating half-tooth gear 75, in conjunction with the rack 74, drives the movable plate 73 to reciprocate linearly within the slide groove 72. The movable plate 73 is fixed to the support column 8, which in turn drives the colored ball 9 to reciprocate linearly. The user's eyes are focused on the colored ball 9, and their eyes follow the movement of the colored ball 9 to achieve strabismus correction training. When amblyopia correction training is needed, the positioning thread knob 5 is manually loosened, and the end of the positioning thread knob 5 disengages from the support plate 1, allowing the guide column 2 to rotate. After the guide column 2 rotates 180 degrees, the display screen 12 is positioned above. Then, the positioning thread knob 5 is tightened, and the positioning thread knob 5 abuts against the outer wall of the support plate 1. The friction force fixes the angle of the guide column 2. The display screen 12 is connected to the computer and power supply, and displays amblyopia correction images for amblyopia correction training of the user.

[0030] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
