Technical Field
[0001] This invention relates to the field of medical device technology, specifically to a multi-purpose ophthalmic examination device. Background Technology
[0002] This multi-purpose ophthalmic examination device integrates multiple functions, accurately measuring key indicators such as visual acuity, intraocular pressure, and corneal curvature. Equipped with a high-definition imaging system, it can clearly observe the fine structures of the fundus and cornea. It is easy to operate and provides ophthalmologists with comprehensive and efficient diagnostic support, assisting in precision diagnosis and treatment.
[0003] Ophthalmic diseases are complex and diverse, involving multiple aspects such as visual acuity, intraocular pressure, cornea, and fundus. Multi-purpose examination devices can integrate multiple functions, such as visual acuity testing, intraocular pressure measurement, corneal topography analysis, and fundus imaging, thereby meeting the needs of ophthalmologists for comprehensive diagnosis and avoiding missed or misdiagnosis. Therefore, multi-purpose ophthalmic examination devices are needed. However, traditional multi-purpose ophthalmic examination devices are not convenient for fixing the head. Even slight head movements can cause tomographic errors in the imaging of fundus structures, affecting the judgment of details such as retinal thickness and macular degeneration. At the same time, when illuminating the eyes with a flashlight, it is not convenient to adjust the angle of the flashlight. Different eye structures present different characteristics under different lighting angles. If the flashlight angle is fixed or inconvenient to adjust, doctors may not be able to observe the full picture and details of the eye, leading to missed or misdiagnosis. Summary of the Invention

The lighting component 6 includes a clamp 61 located on the outside of the first fixing ring 51, and a flashlight 62 is installed on the inner wall of the clamp 61. The clamp 61 is used to fix the flashlight 62, which can be easily installed and removed, and at the same time provides stable support for the flashlight 62. The flashlight 62 is a light source that provides the light required for the examination. Its illumination angle can be changed by adjusting the component 5 to adapt to different ophthalmic examination items. It is noted that the flashlight 62 in the ophthalmic multi-purpose examination device is designed specifically for eye examination. It uses an LED light source, and the brightness is usually between 100 and 200 lumens and is adjustable to avoid strong light from damaging the eyes.
[0023] The drive assembly 3 includes a handle 31 that rotates on the inner wall of the base 1. One end of the handle 31 is fixedly connected to a threaded rod 32, and one end of the threaded rod 32 is rotatably connected to the inner wall of the base 1. The handle 31 is manually rotated to drive the threaded rod 32 to rotate. The threaded structure on the outer side of the threaded rod 32 enables the two sets of moving blocks 7 to move towards or away from each other, thereby driving the positioning assembly 4 to move.
[0024] Two sets of moving blocks 7 are threadedly connected to the outer side of the positive and negative threaded rod 32. A connecting seat 8 is fixedly connected to the top of the moving block 7, and the top of the connecting seat 8 is fixedly connected to the bottom of the moving plate 41. When the positive and negative threaded rod 32 rotates, the two sets of moving blocks 7 will move towards or away from each other, driving the connecting seat 8 and the moving plate 41 to move, thereby achieving the positioning function. The connecting seat 8 serves to connect the moving block 7 and the moving plate 41, transmitting the movement of the moving block 7 to the moving plate 41.
[0025] The top of the connecting seat 8 is rotatably connected to the connecting rod 9 via a rotating shaft. The inner wall of the connecting rod 9 is rotatably connected to the connecting rod 10 via a rotating shaft. One end of the connecting rod 10 is fixed to the mounting post 11. The bottom of the mounting post 11 is rotatably connected to the fixing block 12, and the bottom of the fixing block 12 is fixedly connected to the inner wall of the base 1. The inner wall of the fixing block 12 is rotatably connected to the outer side of the positive and negative threaded rod 32. The connecting rod 9 is set to rotatably connect with the connecting rod 10. The connecting rod 10 and the connecting rod 9 cooperate to realize motion transmission and direction change, and assist the adjustment function of the device. The mounting post 11 is used to provide installation support for the connecting rod 10, and the fixing block 12 is used to provide rotational support for the mounting post 11.
[0026] A mounting bracket 13 is fixed to the top of the base 1. Two motors 14 are mounted on the top of the mounting bracket 13. The output end of the motor 14 is fixedly connected to the inner wall of the second mounting ring 52. A ball 15 is movable on the inner wall of the mounting bracket 13. A sleeve rod 16 is fixed to the outer side of the ball 15, and one end of the sleeve rod 16 is fixedly connected to the inner wall of the clamp 61. The mounting bracket 13 provides mounting support for the motor 14 and the ball 15, ensuring the stable operation of the motor 14 and the ball 15. The motor 14 drives the second mounting ring 52 to slide within the first mounting ring 51 by rotation, thereby adjusting the angle of the lighting component 6. The ball 15 can move within a certain range within the fixed frame 13, providing a base for the movement of the sleeve 16 and assisting in the multi-angle adjustment of the lighting component 6. Through the extension and retraction of the sleeve 16 and the movement of the ball 15, the illumination angle and position of the flashlight 62 can be further flexibly adjusted. It should be noted that the ball 15 can rotate in multiple directions and move within a certain range within the fixed frame 13, providing a flexible base for the movement of the sleeve 16 and assisting in the multi-angle adjustment of the flashlight 62. It should be noted that the sleeve 16 includes two sets of sliding rods, one set fixed to the outside of the ball 15 and the other set fixed to the clamp 61.
[0027] A vertical plate 17 is fixedly connected to the top of the base 1, and two sets of vertical plates 17 are provided. A first fixing frame 18 is fixedly connected to one side of the vertical plate 17, and two first fixing frames 18 are provided. A second fixing frame 19 is installed on the inner wall of the first fixing frame 18, and two second fixing frames 19 are provided. Limiting shafts 20 are rotatably connected to the inner walls of both the first fixing frame 18 and the second fixing frame 19. An arc-shaped groove 21 is provided on the inner wall of both the first fixing frame 18 and the second fixing frame 19. A lighting lamp 22 is fixedly connected to one side of the second fixing frame 19. The vertical plate 17 is fixed to the top of the base 1, providing vertical support for the first fixing frame 18 and forming the side frame of the inspection equipment. The first fixing frame 18 is fixed to one side of the vertical plate 17, serving as... The second fixed frame 19 serves as the mounting base for the first fixed frame 18, supporting the rotational adjustment of the lighting lamp 22. The second fixed frame 19 is installed on the inner wall of the first fixed frame 18 and rotates via the limiting shaft 20 to adjust the illumination angle of the lighting lamp 22. The limiting shaft 20 connects the first fixed frame 18 and the second fixed frame 19, allowing the second fixed frame 19 to rotate around the shaft while limiting its range of motion. The arc-shaped groove 21 is formed on the inner wall of the first fixed frame 18 and the second fixed frame 19. When the first fixed frame 18 and the second fixed frame 19 are adjusted to a suitable angle, they are fixed by inserting bolts into the arc-shaped groove 21, making the first fixed frame 18 and the second fixed frame 19 stable during operation. The lighting lamp 22 is fixed to one side of the second fixed frame 19, providing auxiliary lighting or light source support at a specific angle.
[0028] Working principle: First, the patient's head is positioned between the two moving plates 41. The handle 31 is manually turned, causing the positive and negative threaded rods 32 to rotate. The positive and negative thread structure causes the two sets of moving blocks 7 to move towards each other. Through the connecting seat 8, the moving plates 41 slide on the inner wall of the support plate 2. The two moving plates 41 approach the patient's head from both sides, and the rubber pads 42 contact the head for positioning, buffering protection, and increasing friction. Then, the motor 14 is started. When the motor 14 rotates, the rotational motion at the output end is converted into the circular motion of the second fixed ring 52, thereby changing the relative position of the sleeve rod 16 and achieving the initial adjustment of the flashlight 62 angle. At the same time, the output end of the other set of motors 14 drives the second fixed ring 52 to slide within the first fixed ring 51. At this time, one end of the sleeve rod 16 moves with the second fixed ring 52. At the other end, the ball 15 moves within the fixed frame 13, thereby driving the clamp 61 and flashlight 62 to initially adjust the illumination angle. Based on the effect of the initial adjustment, the sleeve 16 is further operated. Through the extension and retraction of the sleeve 16 and the flexible movement of the ball 15 within the fixed frame 13, the illumination angle and position of the flashlight 62 are finely adjusted so that its light can be accurately focused on the area of the eye that needs to be examined. After the angle adjustment is completed, the flashlight 62 is turned on. It uses an LED light source with a brightness between 100 and 200 lumens, which is adjustable to avoid strong light damaging the eyes. The doctor uses the light provided by the flashlight 62 to conduct a comprehensive and detailed examination of the patient's eyes, completing the entire ophthalmological examination process. At the same time, the upright plate 17 provides vertical support for the first fixed frame 18. As a mounting base, the second fixed frame 19 mounted on its inner wall is rotatably connected via a limiting shaft 20. When the illumination angle of the lighting lamp 22 needs to be adjusted, the second fixed frame 19 is manually pushed to rotate around the limiting shaft 20. At this time, the arc-shaped groove 21 formed on the inner wall of the first fixed frame 18 and the second fixed frame 19 plays a role. It provides trajectory guidance for the rotation of the second fixed frame 19, while limiting its range of motion to prevent excessive rotation. After adjusting to the appropriate angle, the operator inserts bolts into the arc-shaped groove 21 and tightens them to stabilize the first fixed frame 18 and the second fixed frame 19. At this time, the lighting lamp 22 fixed on one side of the second fixed frame 19 can stably provide auxiliary lighting or light source support at a specific angle, meeting the needs of different ophthalmological examination scenarios. The base 1 is used to fix the support plate 2. The support plate 2 is used to limit the sliding of the movable plate 41 in the positioning component 4, assisting the positioning component 4 in positioning the patient's head. The movable plate 41 slides on the inner wall of the support plate 2 and moves under the drive of the drive component 3 to approach or move away from the patient's head from both sides to achieve positioning of the patient's head. The rubber pad 42 is used to contact the patient's head, playing a buffering and protective role, increasing patient comfort, and at the same time enhancing the friction with the head to improve positioning stability. The first fixing ring 51 is circular and rotates under the drive of the motor 14. When the first fixing ring 51 rotates, the sleeve rod 16 can rotate along the second fixing ring 52, thereby driving the lighting component 6 to move through the sleeve rod 16.The angle of the lighting component 6 can then be adjusted. The second fixing ring 52 can rotate under the drive of the motor 14, allowing the sleeve 16 to move along the inner wall of the first fixing ring 51, thereby adjusting the angle of the lighting component 6 to meet different inspection needs.
