Description

Technical Field

[0001] This utility model relates to an interactive blind box teaching aid for diabetic retinopathy, belonging to the field of medical teaching aid technology. Background Technology

[0002] Diabetic retinopathy (DR), a common ophthalmic complication in diabetic patients, has become a critical issue in ophthalmology due to the increasing number of diabetic patients. However, current educational tools for diabetic retinopathy are relatively limited, relying mainly on text, images, and videos. While these media can convey some knowledge, they lack interactive experiential tools, particularly in terms of visual and tactile perception, to help patients or the public gain a deeper understanding of the disease process and pathological characteristics.

[0003] Currently, common educational tools for diabetic retinopathy mainly fall into the following categories:

[0004] Two-dimensional illustrations and video demonstrations are commonly used in public education on diabetic retinopathy. While these methods clearly present the visual characteristics of the lesions, they lack tactile feedback, making it difficult for patients to truly "feel" the changes caused by the disease. Furthermore, this approach hinders patients from translating their knowledge into practical actions for disease prevention and management in their daily lives.

[0005] Traditional specimens and models. Existing diabetic retinopathy models are mostly displayed through simulated fundus images or illustrations. While these clearly show visual changes in the fundus, they lack interactivity and experiential elements. Patients or the public can only learn by viewing static models or pictures, unable to perceive the sensory differences between different disease stages through touch. Moreover, these models are usually static and cannot dynamically demonstrate the disease process, making it difficult to stimulate users' learning interest and promote a deeper understanding of disease progression.

[0006] 3D-printed eyeball models. Although 3D-printed eyeball models have begun to be used in medical education, they lack interactivity in teaching activities. Patients or learners cannot feel the differences in disease stages through touch, making it difficult for patients to deepen their understanding of the disease from a tactile perspective.

[0007] Therefore, an interactive blind box educational tool for diabetic retinopathy was designed. Using 3D printing technology, tactile models of different stages of diabetic retinopathy were created. Through tactile interaction, patients and the public can better understand the different stages of diabetic retinopathy. Utilizing the highly interactive nature of blind boxes, learners can directly perceive the characteristics of the disease through touch, providing an immersive learning experience and enhancing their understanding of the disease process. Learners can gain a more intuitive understanding of diabetic retinopathy through touch and sight, achieving a more ideal popular science and teaching effect. Summary of the Invention

[0008] The technical problem to be solved by this utility model is to provide an interactive blind box teaching aid for diabetic retinopathy. It not only improves the lack of interactivity in current teaching aids for diabetic retinopathy, but also solves the problem that the eyeball model inside the blind box teaching aid cannot be quickly cleaned and disinfected during use.

[0009] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0010] An interactive blind box educational tool for diabetic retinopathy, comprising:

[0011] The blind box body has two inner cavities, including an upper interactive touch cavity and a lower driving cavity. The interactive touch cavity is an opaque cavity. An interactive opening that allows a hand to enter is provided on the side of the interactive touch cavity. A hollow rotating platform is rotatably installed at the bottom of the interactive touch cavity.

[0012] A diabetic retinopathy eye model, comprising multiple eye models with different lesion characteristics at various stages of diabetic retinopathy, each eye model being connected to a rotating rod, each rotating rod being radially distributed along a hollow rotating platform and rotatably mounted at the same circumferential position on the hollow rotating platform;

[0013] A rotation drive module, comprising a revolution drive mechanism and a rotation drive mechanism installed in the drive cavity, wherein the revolution drive mechanism drives the hollow rotating platform to revolve around its own central axis, and the rotation drive mechanism drives the eyeball model to rotate around the central axis of the rotating rod.

[0014] The cleaning module includes an arc-shaped groove fixed on the orbital track of the eyeball model, and a disinfecting sponge built into the arc-shaped groove. When the eyeball model passes through the inside of the arc-shaped groove, it is squeezed and wiped by the disinfecting sponge.

[0015] Preferably, the revolution drive mechanism includes a hollow rotating shaft, a worm gear, a worm, and a servo motor. The hollow rotating shaft is rotatably installed in the drive cavity. The top of the hollow rotating shaft is fixed to the hollow rotating platform in the interactive touch cavity. A worm gear is coaxially fixed on the outer circumference of the middle part of the hollow rotating shaft. The worm gear meshes with the worm driven by the servo motor.

[0016] Preferably, the self-rotating drive mechanism includes a central shaft, a first bevel gear, and a second bevel gear. The central shaft is coaxially inserted into the hollow rotating shaft and fixed to the bottom of the blind box body. The upper end of the central shaft is higher than the hollow rotating platform and coaxially fixed to the first bevel gear. A second bevel gear is fixed on each rotating rod, and the second bevel gear meshes with the first bevel gear.

[0017] Preferably, the blind box body at the top of the interactive opening is provided with an openable flip cover.

[0018] Preferably, the inside of the interactive opening is provided with an elastic cloth cover to block the view.

[0019] Preferably, the arc-shaped groove is connected to the top of the blind box body through a connecting pipe, and disinfectant is injected into the disinfectant sponge inside the arc-shaped groove through the connecting pipe.

[0020] Preferably, the cross-section of the disinfectant sponge in the arc-shaped groove has a circular cavity for wiping the eyeball model and a rectangular cavity for wiping the rotating rod. The inner diameter of the circular cavity is smaller than the outer diameter of the eyeball model, and the width of the rectangular cavity is smaller than the diameter of the rotating rod.

[0021] The beneficial effects of this utility model are:

[0022] (1) When using blind box teaching aids for teaching or experience, the opaque blind box body can ensure that learners cannot directly see the eye model inside the box. Through the interactive opening, learners can put their hands into the blind box body to touch and experience it. Through the revolution drive mechanism, the eye model of each disease stage can be rotated to the interactive opening position so that users can feel the tactile characteristics of the eye model at that stage. This allows learners to directly distinguish the different stages of diabetic retinopathy through touch, enhancing their understanding and memory of diabetic retinopathy.

[0023] (2) The cleaning module can be used to perform all-round cleaning and disinfection of the eyeball model that maintains revolution and rotation during switching during use;

[0024] (3) The self-locking drive method of unidirectional transmission of worm and worm wheel can prevent the eyeball from moving when the learner touches the eyeball model, which is conducive to the stable positioning of the eyeball model. Attached Figure Description

[0036] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0037] like Figure 1 , Figure 2 As shown, this interactive blind box teaching aid for diabetic retinopathy includes: a blind box body 1 for covering the learner's line of sight, a diabetic retinopathy eyeball model 2 built into the blind box body 1, a rotation drive module for driving the diabetic retinopathy eyeball model 2 to perform revolution and rotation, and a cleaning module 5 for cleaning and disinfecting the diabetic retinopathy eyeball model 2 during switching.

[0038] The blind box body 1 is made of opaque plastic or metal material. It has two inner cavities: an upper interactive touch cavity 101 and a lower driving cavity 102. The interactive touch cavity 101 is opaque, and its side has an interactive opening 103 that allows hands to enter. To better obstruct the learner's view, an elastic cloth cover 104 is provided inside the interactive opening 103. When not in use, the elastic cloth cover 104 hangs inside the interactive opening 103, providing obstruction; when in use, the learner inserts their hand into the elastic cloth cover 104 and reaches into the interactive touch cavity 101 to touch the eyeball model 201. A hollow rotating platform 105 is rotatably mounted at the bottom of the interactive touch cavity 101. The bottom of the blind box body 1 is equipped with rubber anti-slip feet 108 for anti-slip and shock absorption.

[0039] like Figure 3 As shown, the diabetic retinopathy eye model 2 includes multiple eye models 201 representing different stages and characteristics of diabetic retinopathy. The eye models 201 are 3D printed. For example, a blind box contains three different stages of diabetic retinopathy eye models 2 (early, middle, and late stages), accurately reproducing the tactile sensation of the lesions based on their different pathological characteristics. The tactile structure includes different tactile shapes and textures designed for each retinopathy model to simulate different stages of diabetic retinopathy, such as early microvascular dilation, middle-stage retinal hemorrhage, and late-stage macular edema. Learners can distinguish the tactile differences of each stage of the disease through touch, helping them perceive the characteristics of different disease stages. Each eye model 201 is connected to a rotating rod 202, and each rotating rod 202 is radially distributed along the hollow rotating platform 105 and rotatably mounted at the same circumferential position on the hollow rotating platform 105. Specifically, multiple fixed seats 109 evenly distributed along the same circumference are installed on the hollow rotating platform 105, and bearings 110 are interference-fitted at the same position in the middle of the rotating rod 202, and the bearings 110 are installed on the fixed seats 109.

[0040] like Figure 3 , Figure 4 As shown, the rotation drive module includes a revolution drive mechanism 3 and a rotation drive mechanism 4 installed in the drive cavity 102. The revolution drive mechanism 3 drives the hollow rotating platform 105 to revolve around its own central axis, and the rotation drive mechanism 4 drives the eyeball model 201 to rotate around the central axis of the rotating rod 202.

[0041] In some embodiments, the revolution drive mechanism 3 includes a hollow rotating shaft 301, a worm gear 302, a worm 303, and a servo motor 304. The hollow rotating shaft 301 is rotatably mounted in the drive cavity 102. The top of the hollow rotating shaft 301 is fixed to the hollow rotating platform 105 in the interactive touch cavity 101. The worm gear 302 is coaxially fixed on the outer circumference of the middle part of the hollow rotating shaft. The worm gear 302 meshes with the worm 303 driven by the servo motor 304. A small gear 305 is fixed on the rotating shaft of the servo motor 304, and a large gear 306 is fixed at one end of the worm 303. The small gear 305 meshes with the large gear 306 of the motor, driving the worm 303 to rotate. The gear ratio of the small gear 305 to the large gear 306 is 1:2-1:3, which reduces the speed of the servo motor 304.

[0042] The servo motor 304 can precisely control its rotation angle thanks to the coordinated operation of its closed-loop control system and high-precision encoder. By receiving pulse signals from the controller, the servo motor 304 can precisely rotate to a specified angular position. The encoder monitors the motor's rotation angle in real time and transmits feedback signals back to the controller. The controller then adjusts the motor's rotation using a PID algorithm to ensure that the actual angle matches the target angle.

[0043] When the servo motor 304 drives the hollow rotating platform 105 to rotate, it can precisely rotate each eye model 201 to the interactive opening 103 by pre-programming and setting the angle of each rotation (for example, dividing the platform into three equal parts, each part corresponding to the position of the eye model 201 in the early, middle and late stages). This allows learners to touch specific eye models 201 with their hands, thus achieving the purpose of interactive learning.

[0044] In the revolution drive mechanism 3, the unique unidirectional transmission characteristics and self-locking properties of the worm gear 302 and worm 303 are cleverly utilized. The unidirectional transmission characteristic means that power can only be transmitted from the worm 303 to the worm gear 302 in a specific direction, while reverse transmission is not possible. At the same time, the self-locking property determines that once the drive stops at a certain position, the worm gear 302 and worm 303 will be firmly locked and will not rotate due to minor external disturbances.

[0045] Based on these characteristics of the worm gear 302 and worm 303, when the learner touches the eye model 201 with their hand, it can prevent the eye model 201 from moving. The eye model 201 is always firmly locked in its original position, ensuring that the learner can have a stable tactile experience.

[0046] like Figures 3-5As shown, in some embodiments, the self-rotating drive mechanism 4 includes a central shaft 401, a first bevel gear 402, and a second bevel gear 403. The central shaft 401 is coaxially inserted into the hollow rotating shaft and fixed to the bottom of the blind box body 1. The upper end of the central shaft 401 extends above the hollow rotating platform 105 and is coaxially fixed to the first bevel gear 402. A second bevel gear 403 is fixed on each rotating rod 202, and the second bevel gear 403 meshes with the first bevel gear 402.

[0047] The self-rotation drive mechanism 4 cleverly utilizes multiple cooperating bevel gears to achieve rotation control of multiple eyeball models 201. The core of this mechanism relies on a stationary first bevel gear 402 as the rotation center. Multiple second bevel gears 403 mounted on a hollow rotating platform 105 mesh with the first bevel gear 402. While the servo motor 304 drives the hollow rotating platform 105 to revolve, the platform simultaneously drives the first bevel gear 402 to rotate along the stationary second bevel gears 403. The rotation of the second bevel gears 403 causes the multiple eyeball models 201 to rotate on their own axes. Through this design, a single servo motor 304 can simultaneously drive all eyeball models 201 to complete both rotation and revolution, making the entire mechanism's movement more coordinated and efficient, suitable for scenarios requiring simulation of eyeball movement.

[0048] like Figure 2 , Figure 5 , Figure 6 As shown, the cleaning module 5 includes an arc-shaped groove 501 fixed on the orbital track of the eyeball model 201, and a disinfecting sponge 502 built into the arc-shaped groove 501. When the eyeball model 201 passes through the interior of the arc-shaped groove 501, it is squeezed and wiped by the disinfecting sponge 502.

[0049] By utilizing the revolution and rotation of the eyeball model 201, when different eyeball models 201 switch positions, the eyeball model 201 that has just been touched will enter the arc-shaped groove 501. Through rotation, the eyeball model 201 can be squeezed and wiped by the disinfecting sponge 502 in 360°. The cleaning and disinfection are more comprehensive.

[0050] In some embodiments, the arc-shaped groove 501 is connected to the top of the blind box body 1 via a connecting pipe 503, and disinfectant is injected into the disinfectant sponge 502 inside the arc-shaped groove 501 through the connecting pipe 503. The cross-section of the disinfectant sponge 502 in the arc-shaped groove 501 has a circular cavity 504 for wiping the eyeball model 201 and a rectangular cavity 505 for wiping the rotating rod 202. The inner diameter of the circular cavity 504 is smaller than the outer diameter of the eyeball model 201, and the width of the rectangular cavity 505 is smaller than the diameter of the rotating rod 202. The eyeball model 201 and the rotating rod 202 are centrally located within the circular cavity 504 and the rectangular cavity 505.

[0051] The eyeball model 201 and the rotating rod 202 are both revolving and rotating. The circular cavity 504 can wipe and disinfect the surface of the eyeball model 201 from all directions, while the rectangular cavity 505 is used to wipe and disinfect the rotating rod 202 from all directions.

[0052] In some embodiments, a liquid storage chamber 506 is provided at the upper part of the arc-shaped groove 501. The top of the liquid storage chamber 506 is connected to the outside through a connecting pipe 503, and the bottom of the liquid storage chamber 506 is provided with micropores 507 that communicate with the disinfectant sponge 502 below. The disinfectant sponge 502 slowly absorbs the disinfectant in the liquid storage chamber 506 through the micropores 507 (inner diameter 0.2-1mm) for wiping disinfection. By providing the liquid storage chamber 506, a larger amount of disinfectant can be injected at once through the connecting pipe 503, avoiding the problem of frequent disinfectant injection.

[0053] like Figures 1-3 As shown, in some embodiments, the blind box body 1 at the top of the interactive opening 103 is provided with an openable flip cover 106. The flip cover 106 is connected to the blind box body 1 by a hinge, and a handle 107 is provided on the flip cover 106 for easy manual opening.

[0054] To verify the accuracy of the judgment after tactile interaction, the eye model 201 needs to be visually presented to the learner. Therefore, an openable blind box structure 1 is designed. After tactile interaction, the learner first states which stage of diabetic retinopathy the touched eye model 201 belongs to, then opens the flip cover 106 and visually observes whether the judgment is correct. This method of mutual verification through vision and touch strengthens the memory of the eye characteristics of diabetic retinopathy.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
