Technical Field

[0001] The invention relates to the technical field of teaching models, in particular to a model for practicing wearing orthokeratology lenses. Background Art

[0002] Orthokeratology lenses are a medical device that can temporarily change the shape of the cornea and correct myopia. They are widely used in the field of myopia prevention and control. At present, when novices learn to wear orthokeratology lenses, they mainly rely on text instructions, video tutorials, and direct eye operation practice under guidance. However, text and videos lack a sense of practical experience, and direct eye practice poses a risk of injury.

[0003] The traditional model wearing practice method has many shortcomings. On the one hand, it is impossible to accurately judge whether the lens is completely stuck in the surface of the eyeball. On the other hand, most of the practice models are placed in front of the user, and it is impossible to intuitively experience the feeling of wearing it, and it cannot meet the learners' needs to practice in a more realistic scene. Summary of the invention

[0004] In response to the problems in the prior art, the present invention provides a model for practicing the operation of wearing orthokeratology lenses. In order to solve the above-mentioned problems, the present invention proposes a model for practicing the operation of wearing orthokeratology lenses, which solves the problem that the existing model cannot intuitively experience the feeling of wearing the lenses and cannot meet the learners' needs for practicing in a more realistic scenario.

[0007] Specifically, the inner diameter of the card slot and the corresponding slot are both matched with the outer diameters of the first pressure sensor and the second pressure sensor.

[0008] Specifically, a notch in a funnel shape is formed at one end of the support rod.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] like Figure 1-Figure 7 As shown, the present invention provides the following technical solutions: Embodiment 1: A model for practicing wearing orthokeratology lenses, comprising a model component 1 for being worn on the head, the model component 1 comprising a model body 11, an eye rubber cover 12 being fixedly connected to the model body 11 on the side facing the face, an elastic strap 13 being arranged between the two outer walls of the model component 1, and two eye grooves 101 being symmetrically arranged on the outer wall on the other side of the model component 1, and eyeballs 14 being fixedly installed inside the two eye grooves 101.

[0018] When in use, the model body 11 is first worn on the learner's head through the elastic strap 13, so that the eye rubber cover 12 is attached to the outer end of the learner's eye. The elastic strap 13 can adapt to more different learners, and the setting of the eye rubber cover 12 can protect the learner's eye safety.

[0019] Embodiment 2: The technical solution that distinguishes this embodiment from Embodiment 1 includes: a wearing component 2 for wearing a corneal reshaping lens is provided at the lower end of the other outer wall of the model body 11, and the wearing component 2 includes a reshaping lens body 21, and a hand-held rod 24 is fixedly connected to the bottom end of the reshaping lens body 21, and an elastic connecting rope 25 connected to the bottom end of the model body 11 is fixedly connected to the bottom end of the hand-held rod 24, and a support rod 26 fixedly connected to the outer wall of the model body 11 is provided at the outer end of the hand-held rod 24, and a funnel-shaped notch 201 is provided at one end of the support rod 26, and a card slot 103 and a corresponding slot 104 are provided on the surface of the two eyeballs 14, and the inner diameters of the card slot 103 and the corresponding slot 104 are adapted to the outer diameters of the first pressure sensor 22 and the second pressure sensor 23, and audio players 27 are provided on both sides of the eye rubber cover 12 of the model body 11, and the audio players 27 are electrically connected to the second pressure sensor 23.

[0020] When in use, first wear the model body 11 on the head through the elastic strap 13, so that the eye rubber cover 12 is attached to the outer end of the learner's eye, and then pick up the reshaping lens body 21 through the hand-held rod 24 and align it with the eye groove 101. Then, when either the first pressure sensor 22 or the second pressure sensor 23 is inserted into the card slot 103 and the corresponding groove 104, the audio player 27 will be triggered to issue a deviation voice prompt. When the first pressure sensor 22 and the second pressure sensor 23 are all inserted into the card slot 103 and the corresponding groove 104, the audio player 27 will be triggered to prompt a reminder of correct wearing, thereby avoiding the problem of not being able to accurately judge whether the lens is completely inserted.

[0021] Embodiment 3: The technical solution of this embodiment is different from that of Embodiment 2 and includes: the model body 11 is located between the two eye grooves 101 and is provided with an adjustment component 3 for simulating the opening and closing of the eyelids. The adjustment component 3 includes a reciprocating cylinder 31. The output end of the reciprocating cylinder 31 is fixedly connected to a driving rod 32. The bottom end of the driving rod 32 is fixedly connected to a lifting rod 33. The edges on both sides of the bottom end of the lifting rod 33 are fixedly connected to rack plates 35. The two rack plates 35 are meshedly connected to transmission gears 36. The outer walls of the two transmission gears 36 are fixedly connected to a rotating rod 37 that penetrates the eye groove 101. One end of the rotating rod 37 is fixedly connected to an arc-shaped baffle 38. The arc A third pressure sensor 39 is fixedly connected to the bottom end of the arc baffle 38, a controller 311 is fixedly installed on the upper end of the other outer wall of the model body 11, a receiving groove 301 is opened inside the model body 11 near the two eye grooves 101, and sliding grooves 302 are opened on both inner side walls of the receiving groove 301. Slide blocks 34 are slidably connected to the inner walls of the two sliding grooves 302, and the two slide blocks 34 are fixedly connected to the lifting rod 33. An annular groove 102 is opened near the outer end of the eye groove 101 of the model body 11, and the arc baffle 38 is located in the annular groove 102, and the third pressure sensor 39 is electrically connected to the reciprocating cylinder 31 through the controller 311.

[0022] During use, when the learner is wearing the reshaping lens body 21, since the simulation requires a real experience, the reciprocating cylinder 31 is started to drive the lifting rod 33 to move downward through the driving rod 32, and the lifting rod 33 will drive the transmission gear 36 to rotate through the meshing of the rack plate 35. At this time, the transmission gear 36 will drive the arc baffle 38 to rotate back and forth through the rotating rod 37, thereby simulating the opening and closing of the eyelids. However, when actually wearing it, the eyelids will contract due to physiological reasons, which will affect normal wearing. When the arc baffle 38 rotates and contacts the finger through the third pressure sensor 39, the controller 311 outputs an instruction to move the reciprocating cylinder 31 upward, so that the arc baffle 38 is expanded upward. In this way, the experience of actually wearing the reshaping lens body 21 can be simulated, so that learners can master the wearing skills faster.
