Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a lens sorting device for visual function treatment. Background Art

[0002] Lens sorting training is a visual training method that aims to train the relaxation and stimulation of perceptual accommodation through monocular accommodation training techniques. During lens sorting training, one eye is covered and 6 to 8 lenses are placed in front of the patient, who is asked to sort them from strongest to weakest focusing, with the strongest lenses being the most difficult to accommodate and the weakest lenses being the most relaxing for the eyes. Currently, visual function lens sorting training uses loose lenses from lens boxes, which causes children to carefully observe the numbers on the lenses during training, resulting in poor training results. Furthermore, when picking up the lenses, children may accidentally touch the center of the lenses, making the lenses blurry and not conducive to training. After a patient uses the loose lenses, nurses need to clean and disinfect them one by one, which is very time-consuming. Summary of the Invention

[0003] In order to solve the above problems, the purpose of the present invention is to provide a lens sorting device for visual function treatment, which can guide children to give the most realistic sorting, better complete the training and improve the training effect.

[0004] The technical solution to solve the above problem is: a lens sorting device for visual function treatment, including a main body plate, one side of the main body plate is provided with a plurality of card slots adapted to the handles of the lenses along the length direction of the main body of the main body, one side of the card slot is the front of the main body plate, and the other side of the card slot is provided with a visual window, and the visual window is located on the back of the main body plate, and serial numbers are marked on the front and back of the main body plate, each serial number corresponds to a card slot, and a handle is provided at the bottom of the main body plate.

[0005] A further technical solution is that a transparent cover is installed on the visible window of the card slot, and the shape of the transparent cover is adapted to the shape of the card slot.

[0006] Its further technical solution is: it also includes a timer, which is installed on the top of the main body plate.

[0007] A further technical solution is that a layer of transparent plate is pasted on the back of the main body plate.

[0008] A further technical solution is that the number of the card slots is 6 to 8.

[0009] Due to the adoption of the above technical solution, the lens sorting device for visual function treatment of the present invention has the following characteristics and beneficial effects:

[0010] 1. This new lens sorting device for visual function therapy effectively conceals lens markings, guiding children to give realistic sorting, thereby improving training effectiveness. Furthermore, it prevents children from handling the lenses during training, reducing the risk of nosocomial infections and saving disinfection time.

[0011] 2. The timer on the lens sorting device for visual function treatment of the present invention can meet the speed training timing of lens sorting training, which is convenient for training use.

[0012] 3. The lens sorting device for visual function treatment of the present invention stores the lenses together, preventing the loose lenses from being scattered and dropped on the ground, thereby reducing loss. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 1-Figure 3 As shown, a lens sorting device for visual function treatment includes a main body plate 1, and one side of the main body plate 1 is provided with a plurality of slots 13 that are compatible with the handles 41 of the lenses 4 along the length direction of the main body of the main body. The shape of the slots 13 can be designed according to the handles 41 of different lenses. The number of the slots 13 is generally 6 to 8. One side of the slots 13 is the front side 11 of the main body plate, and the other side of the slots 13 is provided with a visual window 14. The visual window 14 is located on the back side 12 of the main body plate to facilitate the doctor to observe the markings of the lenses. The front side 11 and the back side 12 of the main body plate are marked with serial numbers, and each serial number corresponds to a slot 13, for example Figure 1 The front side 11 of the main body panel is marked with serial numbers 1 to 7, and the back side 12 of the main body panel is also marked with serial numbers 1 to 7. Each serial number corresponds to a card slot 13, and the 7 serial numbers correspond to 7 card slots respectively. The serial numbers marked on the front and back of the same card slot are the same. A handle 2 is provided at the bottom of the main body panel 1 for easy handling.

[0028] The visible window 14 of the card slot 13 is provided with a transparent cover 15, the shape of which is adapted to the shape of the card slot 13. Figure 9 . Example 2:

[0029] like Figure 7 、 Figure 8As shown, a lens sorting device for visual function treatment is basically the same in structure as the lens sorting device for visual function treatment described in Example 1. The difference is that: the device of this Example 2 also includes a timer for calculating the time required for the sorting process. The timer is installed on the top of the main plate 1 to facilitate speed training timing. Combining the timer with the main plate 1 eliminates the need for additional timing tools, making the device more complete and more convenient to carry and use. Example 3:

[0030] A lens sorting device for visual function treatment, which has a structure similar to that of the lens sorting device for visual function treatment described in Example 1, except that a transparent plate 16 is attached to the back of the main plate 1. Figure 10 , used to replace the function of the cover body 15 in embodiment 1, and the transparent plate 16 is used to cover the visible window, making it more convenient for doctors to observe the markings on the lens.

[0031] The main body plate 1 in this embodiment is a rectangular parallelepiped made of an opaque material.

[0032] The method of using the lens sorting device for visual function treatment is as follows: the doctor randomly inserts the lenses that need to be sorted into the card slot 13 of the main board of the device, that is, inserts the handle 41 of the lens into the card slot 13 (see Figure 4-Figure 6 ). The child picks up the device by the handle 2 (holding the device horizontally) and looks at the sight mark one by one according to the lenses on the serial number, with the front 11 of the main body panel facing the child's eyes. The doctor records the serial numbers to help sort the sight marks according to the child's description of how clear the lenses are when looking at the sight marks. For example, the child says that lens No. 5 is the clearest, followed by No. 3, No. 6, No. 7, No. 2, No. 1, and No. 4. The doctor records the serial numbers as 5, 3, 6, 7, 2, 1, and 4. The doctor can view the marks on the lenses with the corresponding serial numbers through the visual window 14 on the back 12 of the main body panel, and compare the order of the marks to see if they are sorted from the strongest to the weakest focus. If the order of the marks meets the requirements, it means that the doctor's order for the child is correct. When timing speed training, the timer on the device can be used to calculate the time required for the sorting process. The qualified time is 3 minutes.

[0033] When using this lens sorting device for visual function treatment, the lens handle 41 is engaged with the slot 13. Because the handle 41 of existing lenses 4 has markings on both the front and back sides, one side of the main plate's slot 13 is the main plate's front face 11, preventing the patient from seeing the markings on the lens and ensuring careful treatment. A visual window 14 is provided on the other side of the slot 13, allowing medical staff to easily observe the markings and assist the patient in sorting. Throughout the treatment process, the patient does not need to touch the lens, reducing the risk of nosocomial infection and saving disinfection time.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the present invention specification, or directly or indirectly applied to the technical fields of other related products, are also included in the patent protection scope of the present invention.
