Description

Technical Field

[0001] The utility model belongs to the technical field of retinal detection, and in particular relates to a retinal detection device based on matrix data analysis. Background Art

[0002] In the medical field, retinal testing is an important part of ophthalmic diagnosis and plays a vital role in the early detection and treatment of various eye diseases. Traditional retinal testing methods usually rely on the doctor's experience and subjective judgment, and the accuracy and repeatability of the test results are limited. Not only is it inefficient, but it is also easily affected by subjective factors, resulting in instability and uncertainty in the test results. With the development of image processing technology and data analysis technology, retinal detection devices based on computer vision have gradually emerged. These devices achieve rapid and accurate diagnosis of eye diseases by automatically acquiring, processing and analyzing retinal images.

[0003] However, the existing retinal detection devices still need to be improved in terms of image acquisition accuracy and processing speed. In particular, image processing technology and data analysis technology require a large amount of data to support them, and therefore a large number of eye photos are needed. However, the existing retinal detection devices can only take photos from a single angle and cannot meet the requirements of matrix data analysis, so accurate results cannot be obtained. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a retinal detection device based on matrix data analysis.

[0005] The technical solution adopted to solve the above technical problems is: a retinal detection device based on matrix data analysis, including a base, a face frame fixedly connected to one side of the top of the base, an operation box provided in the middle of the top of the base, an observation box fixedly connected to the top of the operation box, an observation window fixedly connected to the end of the observation box close to the face frame, a display provided at the end of the operation box away from the face frame, an operation panel installed at the bottom of the display, and the operation panel fixedly connected to the base.

[0006] Furthermore, the face frame is a frame-type structure, the bottom inner end of the face frame is slidably connected to a sliding column, the through end of the sliding column is fixedly connected to a lower top plate, and the top inner end of the face frame is fixedly connected to an upper top plate, and both the lower top plate and the upper top plate are made of rubber.

[0007] Through the above technical solution, the person to be tested fixes his face on the face frame through the lower and upper top plates inside the face frame, which is convenient for retinal testing. The setting of the sliding column enables the lower top plate to adapt to people to be tested of different heights, ensuring that the face maintains an appropriate distance from the observation box, thereby improving the accuracy of the test. The upper and lower top plates made of rubber can provide comfortable support and reduce discomfort during the test.

[0008] Furthermore, longitudinal electric guide rails are fixedly connected to both sides of the middle of the base, transverse electric guide rails are slidably connected between the longitudinal electric guide rails, the middle of the transverse electric guide rails is engaged and slidably connected with the bottom of the operating box, and a support plate is provided on the side of the longitudinal electric guide rail away from the face frame, the bottom end of the support plate is fixedly connected to the base, and the top end of the support plate is rotatably connected to a fixing bracket, and one end of the fixing bracket is fixedly connected to the display.

[0009] Through the above technical solution, the combination of longitudinal and transverse electric guide rails enables the operating box to perform precise three-dimensional movement on the base, thereby adjusting the relative position between the camera and the retina of the person to be tested. The design of the support plate and the fixing bracket ensures the stability and adjustability of the display, allowing the operator to adjust the angle and height of the display as needed to obtain the best observation effect.

[0010] Furthermore, an observation tube is provided inside the observation box, and the observation tube is a T-shaped structure. One end of the observation tube is fixedly connected to the observation window, a lighting lamp is fixedly connected to the top of the observation tube near the observation window, a one-way mirror is fixedly connected to the middle of the observation tube, and a photographic camera is provided at the end of the observation tube away from the observation window, and the photographic camera is slidably connected to the observation box.

[0011] Through the above technical solution, the T-shaped structural design of the observation tube enables the rational layout of the lighting lamp, one-way mirror and camera. The lighting lamp ensures sufficient light for retinal testing, the one-way mirror prevents light from being directly reflected to the camera, and the camera is responsible for capturing the retinal image. The sliding connection design allows the camera to be fine-tuned according to the head size and position of different subjects to obtain the best shooting effect.

[0012] Furthermore, two convex mirrors are slidingly connected inside the bottom end of the observation tube, and the two convex mirrors are symmetrically arranged. Hydraulic push rods are installed on both sides of the convex mirrors. The telescopic ends of the hydraulic push rods are fixedly connected to the surfaces of the convex mirrors. The hydraulic push rods are fixedly connected to the inside of the observation box. The bottom opening of the observation tube is fixedly connected to a conical cover, and the conical cover is located inside the operating box.

[0014] Furthermore, the bottom end of the conical cover is slidably connected to a placement plate, the middle part of the top end of the placement plate is fixedly connected to a photo, the middle part of the bottom end of the placement plate is fixedly connected to a first gear, the bottom end of the first gear is rotatably connected to a slider, the outer side of the slider is slidably connected to a mounting bracket, the mounting bracket is fixedly connected to the operating box, a slide rail is provided in the middle of the mounting bracket, and the slider is slidably engaged with the slide rail.

[0015] Through the above technical solution, the setting of the placement plate allows the operator to easily place photos. The movement of the photos helps to record the various conditions and changes of the retina of the person being tested. The connection method between the first gear and the slider ensures the stable movement of the slider inside the operating box. The movement of the slider drives the mounting frame to slide along the slide rail, thereby achieving precise position adjustment of the photos.

[0016] Furthermore, the four corner positions of the mounting frame are rotatably connected to second gears, two of which are located on different sides, a motor is installed at the bottom end of the second gear, the power output end of the motor is fixedly connected to the second gear, the motor is fixedly connected to the mounting frame, and a belt is slidably connected between the two second gears located on the same side, and a plurality of teeth are provided in the middle of the belt. A single belt is meshed and connected to the two second gears through the teeth, and two belts are meshed and connected to the first gear through the teeth.

[0017] Through the above technical solution, when the second gears on both sides rotate synchronously, the slider can be driven to move; when the second gears on both sides rotate asynchronously, the first gear on the top of the slider can be driven to rotate, thereby realizing precise position adjustment and rotation of the photo placed on the board to adapt to the retinal image comparison requirements of different angles and positions.

[0018] The beneficial effects of the utility model are as follows:

[0019] 1. The T-shaped structure of the observation tube in this invention allows for a rational layout of the lighting, one-way mirror, and camera. The lighting ensures sufficient light for retinal examination, while the one-way mirror prevents light from directly reflecting onto the camera. Meanwhile, the camera is responsible for capturing retinal images. The sliding connection design allows for fine-tuning of the camera according to the head size and position of different subjects to achieve the best possible photographic effect.

[0020] 2. The utility model adopts the design of the first gear and the second gear. When the second gears on both sides rotate synchronously, the slider can be driven to move. When the second gears on both sides rotate asynchronously, the first gear on the top of the slider can be driven to rotate, thereby adjusting the position of the photo. It can achieve precise position adjustment and rotation of the slider. When the eyeballs of the person to be tested rotate following the moving and rotating photo, it is helpful to record and compare the changes in the retinal condition of the person to be tested.

[0034] The working principle of this embodiment is as follows:

[0035] The subject is first guided to the front of the retinal detection device, and the face is positioned by the lower top plate 4 and the upper top plate 5 of the face frame 3 to ensure that the head position is stable. The position of the operating box 7 is adjusted according to the subject's head size and eye position to ensure that the camera 13 can be accurately aimed at the subject's eyes. When everything is ready, the operator starts the device and the lighting lamp 17 provides appropriate light so that the camera 13 can clearly capture the retinal image. The photographic camera 13 captures retinal images through the one-way mirror 18 of the observation tube 16 and displays the images in real time on the display 11 for the operator to observe and analyze. During the testing process, if more retinal images are needed, the operator can adjust the rotation speed and direction of the two motors 31. When the second gears 28 on both sides rotate synchronously, the slider 27 can be driven to move. When the second gears 28 on both sides rotate asynchronously, the first gear 25 on the top of the slider 27 can be driven to rotate, thereby adjusting the position of the photo 22. When the eyeball of the person to be tested rotates following the moving and rotating photo 22, it helps to record various angles of the person's retina and ensure the clarity and accuracy of the image. The entire testing process is managed by the control interface on the operation panel 9. The operator can conveniently control the switching of the lighting 17, the shooting of the photographic camera 13, and the storage and processing of images. The retinal testing device of the present invention can efficiently and accurately complete the detection and analysis of retinal conditions, providing strong support for the early diagnosis and treatment of ophthalmic diseases.
