Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an amblyopia treatment aid device with posture correction function. Background Technology

[0002] Amblyopia is a relatively common childhood eye disease caused by incomplete development of visual ability, retinal damage, or other reversible factors. Current treatment methods usually involve using amblyopia treatment devices. By having children wear these devices, more precise and comprehensive visual training can be provided, which can help improve vision and treat amblyopia more quickly.

[0003] Wearable amblyopia treatment devices are quite heavy for children. Wearing them for extended periods can cause significant strain on a child's head, leading to fatigue and reluctance to continue treatment, thus affecting the treatment's effectiveness. Furthermore, children are active and move around frequently while wearing these devices. If the prescribed posture is not followed during treatment, the treatment effect will be reduced. In addition, the constant head movements of children can easily cause the amblyopia treatment device to shift away from the child's eyes, further diminishing the treatment's effectiveness. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the background art, the present invention provides an amblyopia treatment assistive device with posture correction function.

[0005] The technical implementation of this invention is as follows: an amblyopia treatment auxiliary device with posture correction function, comprising a nursing bed, a connecting rod rotatably connected to the nursing bed, a mounting shell provided on one side of the nursing bed, the mounting shell being fixedly connected to the connecting rod, a support rod provided on the mounting shell, a headrest slidably connected to the upper end of the support rod, a first movable rod slidably connected to the headrest, a second movable rod slidably connected to the first movable rod, an amblyopia treatment device fixedly connected to the second movable rod, a first limiting pin slidably connected to the first movable rod, a second movable rod having equidistantly distributed first limiting holes, the first limiting pins engaging with adjacent first limiting holes, the first movable rod slidably connected to the second limiting pin, and the headrest having an equidistant array of second limiting holes, the second limiting pins engaging with adjacent second limiting holes. The second movable rod supports the amblyopia treatment device, so that the weight of the amblyopia treatment device acts on the headrest.

[0006] Furthermore, the nursing bed is equipped with a rotating component, which is connected to the connecting rod via a transmission mechanism.

[0007] Furthermore, the support rod is fixedly connected to a limit block, the mounting shell is provided with a limit groove, and the mounting shell is provided with a sliding groove at the limit groove that cooperates with the limit block for limiting.

[0008] Furthermore, both the limiting groove and the sliding groove are arc-shaped, the headrest is rotatably connected to a gear, and the mounting shell is fixedly connected to a gear ring that meshes with the gear.

[0009] Furthermore, the headrest is provided with symmetrically distributed first rotating shafts, with fixed blocks fixed to the first rotating shafts. The fixed blocks are slidably connected to limit rods, and the limit rods are fixed to cheek pads. The limit rods are provided with third limit holes, and the fixed blocks are slidably connected to third limit pins. The third limit pins are matched with the adjacent third limit holes.

[0010] Furthermore, the cheek pads are made of a soft material to accommodate different face shapes.

[0011] Furthermore, the first rotating shaft is fixed with circumferentially equidistant locking blocks, and the headrest is fixed with circumferentially equidistant stop blocks, with the locking blocks and adjacent stop blocks engaging in a limiting cooperation.

[0012] Furthermore, it also includes a buffer assembly, which includes a movable plate slidably connected to the inside of the mounting shell. A movable block is slidably connected to the side of the movable plate near the support rod, and the movable block is rotatably connected to the support rod. A liquid storage tank is fixedly connected to the mounting shell, and the liquid storage tank is connected to a connecting pipe. The connecting pipe stores liquid, and the liquid stored in the liquid storage tank is in a partially filled state. A piston rod is slidably connected to the inside of the connecting pipe, and the piston rod is fixedly connected to the movable plate. A second rotating shaft is rotatably connected to the inside of the connecting pipe through a rotating ring. A spiral fan blade is fixedly connected to the second rotating shaft. The second rotating shaft is fixedly connected to equidistantly distributed first baffles, with gaps between adjacent first baffles. A fixed sleeve is fixedly connected to the inside of the connecting pipe, and the fixed sleeve is rotatably connected to the second rotating shaft. A torsion spring is fixedly connected between the fixed sleeve and the second rotating shaft. Equidistantly distributed second baffles are fixedly connected to the inside of the connecting pipe, with gaps between adjacent second baffles. The second baffles fit against adjacent first baffles.

[0013] Furthermore, the mounting shell is slidably connected with U-shaped rods that are evenly distributed, and the U-shaped rods are slidably connected with symmetrically distributed guide rods. A spring is fixed between the guide rod and the adjacent U-shaped rod, and the guide rod is close to the movable plate.

[0014] Furthermore, there is a gap between adjacent guide rods, the size of which is equal to the thickness of the movable plate.

[0015] The present invention has the following advantages: By adjusting the positions of the first and second movable rods, the height and horizontal position of the amblyopia treatment device can be changed, and the device can be fixed by the second limiting pin and the first limiting hole, so that the weight of the amblyopia treatment device acts on the headrest, preventing fatigue caused by the patient wearing the device; the headrest drives the support rod and movable block to squeeze the movable plate, which in turn squeezes the liquid through the piston rod. The fan blade drives the second rotating shaft and the equidistantly distributed first baffles to rotate. The first and second baffles block the liquid, reducing the flow area of ​​the liquid and increasing the resistance to the patient's head movement. The faster the patient moves their head, the greater the resistance, preventing children from moving their heads quickly, which could cause the patient's eyes to deviate from the amblyopia treatment device and reduce the treatment effect.

Detailed Implementation

[0028] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] Example 1: An auxiliary device for amblyopia treatment with posture correction function, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the device includes a nursing bed 101. A connecting rod 102 is rotatably connected to the front left side of the nursing bed 101. A mounting shell 103 is located on the left side of the nursing bed 101, and the mounting shell 103 is fixedly connected to the connecting rod 102. A support rod 104 is provided on the mounting shell 103, and a headrest 105 is slidably connected to the upper end of the support rod 104. The headrest 105 is arc-shaped and slidably connected to two symmetrically distributed first movable rods 106. The first movable rods 106 are slidably connected to second movable rods 107. An amblyopia treatment device 108 is fixedly connected between the two symmetrically distributed second movable rods 107. The second movable rods 107 support the amblyopia treatment device 108, so that the weight of the amblyopia treatment device 108 acts on the headrest 105, preventing fatigue caused by the patient wearing the amblyopia treatment device 108. A first limiting pin 109 is slidably connected to the first movable rod 106, and the second movable rods 107 are provided with equidistantly distributed... The first limiting hole 110 and the first limiting pin 109 are engaged with the adjacent first limiting hole 110 to limit the amblyopia treatment device 108 in the vertical direction. The first movable rod 106 is slidably connected to the second limiting pin 111. The upper side of the headrest 105 is provided with symmetrical and equidistant arrays of second limiting holes 112. The second limiting pin 111 is engaged with the adjacent second limiting hole 112. The first movable rod 106 drives the second movable rod 107 to slide along the headrest 105, thereby changing the horizontal position of the amblyopia treatment device 108. The nursing bed 101 is provided with a rotating component 113, which consists of a worm gear, a worm, and a handle. The rotating component 113 is connected to the connecting rod 102 for transmission. The second movable rod 107 supports the amblyopia treatment device 108, so that the weight of the amblyopia treatment device 108 acts on the headrest 105, preventing the patient from becoming fatigued due to wearing the amblyopia treatment device 108 for a long time.

[0030] like Figures 3-5 , Figure 7 and Figure 8As shown, the support rod 104 is fixedly connected to the limiting block 201, and the mounting shell 103 is provided with a limiting groove 202. The mounting shell 103 is provided with a sliding groove 203 at the limiting groove 202 that cooperates with the limiting block 201 for limiting. Both the limiting groove 202 and the sliding groove 203 are arc-shaped, and the centers of the two arcs are at the same position. When the patient uses this device, the patient's neck is located at the center, making it more natural for the patient's head to rotate around the neck. The headrest 105 is rotatably connected to the gear 204, and the mounting shell 103 is fixedly connected to the gear ring 205 that meshes with the gear 204. The upper right side of the headrest 105 is provided with two symmetrically distributed first rotating shafts 206. The first rotating shafts 206 are fixedly connected to the circumferentially equidistantly distributed locking blocks 207, and the headrest 105 is fixedly connected to the circumferentially equidistantly distributed stop blocks 213. The locking blocks 207 and the adjacent stop blocks 213 limit the movement of the headrest 105. In a coordinated manner, the stop block 213 holds the locking block 207 in place, preventing the fixing block 208 from rotating. The first rotating shaft 206 is fixedly connected to the fixing block 208. The fixing block 208 is slidably connected to the limiting rod 209. The limiting rod 209 is fixedly connected to the cheek pad 210. The cheek pad 210 is made of soft material to adapt to different people's face shapes. The cheek pad 210 presses against the patient's cheek, so that when the patient moves their head, the force of the head acts on the cheek pad 210, and at the same time, it fixes the patient's head. The limiting rod 209 is provided with a third limiting hole 211. The upper side of the fixing block 208 is slidably connected to a third limiting pin 212. The third limiting pin 212 is engaged with the adjacent third limiting hole 211. By inserting the third limiting pin 212 into different third limiting holes 211, the position of the cheek pad 210 is fixed.

[0031] When using this device to assist amblyopia patients in treatment, the patient lies on the nursing bed 101 with their head resting on the headrest 105. The caregiver pulls out the second limiting pin 111 and slides the first movable rod 106 to change the horizontal position of the amblyopia treatment device 108, positioning it directly above the patient's eyes. The caregiver then inserts the second limiting pin 111 into the adjacent second limiting hole 112, preventing the first movable rod 106 from moving. The caregiver then pulls out the first limiting pin 109 and moves the position of the second movable rod 107 up and down. 08 is positioned to fit against the patient's eyes, and the first limiting pin 109 is inserted into the adjacent first limiting hole 110. The vertical direction of the amblyopia treatment device 108 is limited, and the weight of the amblyopia treatment device 108 acts on the headrest 105 to prevent the weight of the amblyopia treatment device 108 from acting on the patient's head and causing fatigue. Subsequently, the patient's head needs to be fixed to prevent the eyes from dislodging from the amblyopia treatment device 108 when the patient moves their head. The specific operation is as follows: the nursing staff lifts the two symmetrically distributed fixing blocks 208 upwards, and the fixing blocks 208 drive the adjacent locking blocks 20 7. Move upwards to disengage the circumferentially equidistant locking blocks 207 from the adjacent stop blocks 213. Then, the nurse rotates the fixing block 208, causing it to rotate the adjacent limiting rod 209. When the cheek pad 210 is aligned with the patient's cheek, the nurse lowers the fixing block 208, causing the locking blocks 207 to engage between the adjacent stop blocks 213, preventing the fixing block 208 from rotating. The nurse then pulls out the third limiting pin 212 and adjusts the position of the limiting rod 209, causing it to move the adjacent cheek pad 210 closer to the patient's cheek. When the headrest 10 is in contact with the patient's cheek, the nurse inserts the third limiting pin 212 into the adjacent third limiting hole 211, so that the limiting rod 209 and the cheek pad 210 are limited. The cheek pad 210 presses against the patient's cheek, so that the patient's head and the headrest 105 form a whole. Then, the nurse adjusts the height of the patient's neck to make the patient in a comfortable position. The nurse adjusts the rotating part 113 according to the patient's needs. The mounting shell 103 rotates around the worm gear to tilt the patient's head forward. When the patient is in a comfortable position, the patient informs the nurse to stop adjusting the rotating part 113.

[0032] The nursing staff activates the amblyopia treatment device 108 to begin treatment for visual amblyopia. During treatment, the patient's neck may remain in the same position for an extended period, which could cause discomfort. Therefore, this device allows the patient's neck and head to move according to a prescribed posture and trajectory while assisting in treatment, ensuring the patient maintains the optimal treatment posture and guaranteeing the treatment effect. When the patient tilts their head, they apply force to the cheek rest pad 210, causing the cheek rest pad 210 to move the headrest 105. The headrest 105 then moves the support rod 104, causing the limiting block 201 to slide along the arc-shaped groove 203. The support rod 104 moves along the arc-shaped trajectory of the limiting groove 202, thus enabling the patient to complete the head tilting action centered on the neck, which conforms to the human body. In terms of engineering, during the patient's head tilting process, gear 204 meshes with gear ring 205, causing gear 204 to drive headrest 105 and the patient's head to rotate, thus allowing the patient to tilt and turn their head simultaneously, increasing the range of motion of the patient's neck and allowing the patient's neck muscles to quickly relax. After the patient completes the treatment, the nurse pulls out the third limiting pin 212, releasing the third limiting pin 212 from limiting rod 209 and cheek pad 210. The nurse moves the position of limiting rod 209 so that cheek pad 210 loses contact with the patient. The nurse pulls out the first limiting pin 109 from the adjacent first limiting hole 110. The nurse moves the second movable rod 107 and amblyopia treatment device 108 upwards, allowing the patient's head to leave the headrest 105.

[0033] Example 2: Based on Example 1, such as Figures 9-11As shown, it also includes a buffer assembly, which includes a movable plate 301 slidably connected to the upper side inside the mounting shell 103. A movable block 302 is slidably connected to the rear side of the movable plate 301. The movable block 302 is rotatably connected to the support rod 104. A liquid storage tank 303 is fixedly connected to the front of the mounting shell 103. A connecting pipe 304 is connected to the bottom of the liquid storage tank 303. Liquid is stored in the connecting pipe 304. The liquid stored in the liquid storage tank 303 is in a non-full state, and gas is stored inside it. The connecting pipe 304 is L-shaped. A piston rod 305 is slidably connected inside the connecting pipe 304. The rear end of the piston rod 305 is fixedly connected to the front side of the movable plate 301. A second rotating shaft 306 is rotatably connected inside the connecting pipe 304 via a rotating ring. A fan blade 307 is fixedly connected to the second rotating shaft 306. The fan blade 307 is spiral-shaped. Three first baffles 308 are equidistantly distributed on the second rotating shaft 306. A gap is left between adjacent first baffles 308 for liquid to pass through. A fixed sleeve 309 is fixedly connected inside the connecting pipe 304. The axis of the fixed sleeve 309 is parallel to the second rotating shaft 301. The axes of the two shafts coincide, and the fixed sleeve 309 is rotatably connected to the second rotating shaft 306. A torsion spring for resetting the second rotating shaft 306 is fixed between the fixed sleeve 309 and the second rotating shaft 306. Three equally spaced second baffles 310 are fixed inside the connecting pipe 304. The second baffles 310 are the same size and shape as the first baffles 308. The second baffles 310 and the first baffles 308 simultaneously block the liquid. A gap is left between adjacent second baffles 310 for the flow of liquid. The second baffles 310 and the adjacent first baffles 308... The left side of the mounting shell 103 is slidably connected to three U-shaped rods 311 that are equidistantly distributed. The U-shaped rods 311 are slidably connected to two symmetrically distributed guide rods 312. A spring for resetting the guide rod 312 is fixed between the guide rod 312 and the adjacent U-shaped rod 311. There is a gap between the adjacent guide rods 312, and the size of the gap is equal to the thickness of the movable plate 301. Pushing the U-shaped rods 311 to the right causes the two symmetrically distributed guide rods 312 to fit against the front and rear sides of the movable plate 301, thereby adjusting the resistance experienced by the patient when moving their head.

[0034] Because children are active and prone to shaking their heads while using this device, excessive head shaking can cause their eyes to shift away from the amblyopia treatment instrument 108, reducing the treatment effect. To address this issue, the specific operation is as follows: During head shaking, the patient applies force to the cheek rest 210, causing the headrest 105 to move the support rod 104 along the slide groove 203. The support rod 104 then moves the movable block 302 on the movable plate 301. Simultaneously, the movable block 302 moves the movable plate 301 along the axis of the piston rod 305. When the movable block 302 pushes the piston rod 305, the piston rod 305 compresses the liquid in the connecting pipe 304, causing the liquid to enter the storage tank 303. The pressure of the gas in the storage tank 303 increases. As the liquid in the connecting pipe 304 enters the storage tank 303, it impacts the fan blades 3. 07. The fan blade 307 drives the three circumferentially equidistant first baffles 308 to rotate via the second rotating shaft 306. The torsion spring between the second rotating shaft 306 and the fixed sleeve 309 is twisted. After rotation, the first baffles 308 block the gap between two adjacent second baffles 310, reducing the flow area of ​​the liquid and increasing the resistance to the liquid. This causes resistance to the patient during head shaking. The faster the patient shakes their head, the faster the piston rod 305 squeezes the liquid, and the greater the impact force of the liquid. This causes the second rotating shaft 306 to drive the first baffles 308 to rotate at a larger angle. The first baffles 308 and the second baffles 310 block the liquid, thus increasing the resistance to the liquid. This makes it more difficult for the patient to shake their head, preventing active children from shaking their heads quickly, which could cause the patient's eyes to deviate from the amblyopia treatment device 108 and reduce the treatment effect of the amblyopia treatment device 108.

[0035] When the patient slowly moves their head, the headrest 105 moves the movable plate 301 slowly via the support rod 104, causing the movable plate 301 to squeeze the liquid slowly via the piston rod 305. The liquid flows slowly, and the impact force of the liquid on the second rotating shaft 306 is small. This results in a smaller range of rotation of the second rotating shaft 306 driven by the fan blade 307. Consequently, the blocking effect of the first baffle 308 and the second baffle 310 on the liquid is not obvious, and the liquid experiences less resistance. This makes it easier for the patient to move their head. Slow head movement helps the patient's eyes to stay in close contact with the amblyopia treatment device 108, ensuring the treatment effect of the amblyopia treatment device 108.

[0036] When liquid enters the storage tank 303 from the connecting pipe 304, the gas pressure in the storage tank 303 increases, causing resistance during the patient's head movement. When the device is not in use, the gas pressure is equal to atmospheric pressure, and the movable plate 301 is located between two symmetrically distributed guide rods 312. At this time, the guide rods 312 are not in contact with the movable plate 301. Before the patient lies on the nursing bed 101, the nursing staff pushes an appropriate number of U-shaped rods 311 into the mounting shell 103 according to the patient's condition, so that the two symmetrically distributed guide rods 312 are in contact with the movable plate 301, thereby changing the magnitude of the resistance encountered by the patient during head movement. During the patient's head movement, the movable plate 301 squeezes the adjacent guide rods 312, compressing the springs between the guide rods 312 and the adjacent U-shaped rods 311. When the patient's head no longer exerts force, under the combined action of the spring force between the guide rods 312 and the adjacent U-shaped rods 311 and the gas pressure, the patient's head gradually returns to its original position, so that the patient's eyes are facing upwards, putting the patient in the optimal treatment posture and ensuring the treatment effect.
