Description

Technical Field

[0001] This application belongs to the technical field of visual function examination, and particularly relates to a binocular visual function rapid measurement device. Background Art

[0002] Medically, binocular visual function refers to the images of external objects falling on the corresponding points of the retinas of both eyes. Specifically, the nerve excitation in the macula area is transmitted along the visual perception system into the brain, and in the visual center, the visual signals from both eyes are integrated and analyzed into a complete process with a three-dimensional perception. Binocular visual function is also known as binocular single vision function.

[0003] Furthermore, clinically, binocular visual function is divided into three levels from simple to complex, known as the three-level fusion function, namely simultaneous vision, fusion vision, and stereopsis.

[0004] In one of the existing binocular visual function examination items, using the principle of red-green (or blue) complementary colors, three visual function detection cards with detection patterns are used for visual function examination. On the same visual function detection card, multiple detection patterns of the same size but different colors are vertically spaced from top to bottom. The color arrangement order of the multiple detection patterns on each visual function detection card is the same. However, the sizes of the detection patterns on the three visual function detection cards are designed in different proportions (i.e., the detection patterns on the three visual function detection cards are large, medium, and small pictures respectively). The distance between the subject's eyes and the visual function detection card is 33 cm. The three visual function detection cards are presented in order from large to small, and the subject is asked to identify the detection patterns and the colors of the detection patterns on the visual function detection cards until the three visual function detection cards are tested. Finally, based on the size and color of the detection patterns that the subject can see, it is determined whether the subject's eyes have primary and secondary visual functions, as well as the degree of the primary and secondary visual functions, that is, qualitative and quantitative examinations of the subject's visual function are achieved.

[0005] The above method of using visual function detection cards for visual function examination has the following problems:

[0006] 1. The operation is very inconvenient, and it is necessary to manually pick up and place the visual function detection cards in order.

[0007] 2. During the examination process, the tester needs to hold the visual function detection card by hand, and holding the visual function detection card may block the detection patterns on the visual function detection card.

[0008] 3. The visual function detection cards are prone to loss and inconvenient to find. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] As Figures 1-6 shown, an embodiment of this application provides a binocular vision function rapid measurement device, which includes a handle 1, a central shaft 2, and a rotating body 3. The central shaft 2 is connected to the upper end of the handle 1, the rotating body 3 is sleeved on the central shaft 2, and the rotating body 3 is rotationally connected to the central shaft 2; the rotating body 3 is arranged in a triangular prism shape, and detection patterns (not shown in the figure) are arranged on three side surfaces of the rotating body 3.

[0040] In the embodiment of this application, by providing the handle 1, the central shaft 2, and the triangular prism-shaped rotating body 3, the rotating body 3 is sleeved on the central shaft 2 and the rotating body 3 is rotationally connected to the central shaft 2, and detection images corresponding to the vision function detection cards are arranged on three side surfaces of the rotating body 3. When in use, by holding the handle 1 and rotating the rotating body 3, the detection patterns on different side surfaces of the rotating body 3 can face the person to be tested.

[0041] The binocular vision function rapid measurement device in this embodiment is convenient to operate. When detecting, the holding part will not block the detection pattern, and it is relatively large in volume compared with the vision function detection card. The detection patterns of the three vision function detection cards are integrated in this device and are not easily lost.

[0042] The binocular vision function rapid measurement device in this embodiment can be used for binocular vision function screening, and can also be used for the observation and evaluation of the curative effect after strabismus and amblyopia treatment.

[0043] In one embodiment, the shapes of the detection patterns on the three side surfaces of the rotating body 3 are the same. A plurality of detection patterns are arranged at intervals in the vertical direction on the same side surface. The sizes of the plurality of detection patterns on the same side surface are the same but the colors are different. The color arrangement orders of the detection patterns on two adjacent side surfaces are the same but the sizes are different. With such a setting, the detection patterns on the three side surfaces of the rotating body 3 correspond one by one to the patterns of the three visual function detection cards in the existing visual function examination using three visual function detection cards with detection patterns. Thus, the visual function detection function is realized by integrating the detection patterns of the three visual function detection cards on one device.

[0044] In one embodiment, the sizes of the detection patterns on the three side surfaces of the rotating body 3 are arranged in the order from large to small or from small to large. Specifically, on the three side surfaces of the rotating body 3, the three side surfaces can be numbered respectively according to a preset rotation direction (such as the clockwise direction). For example, the three side surfaces are numbered 1, 2, and 3 in the clockwise direction. Then, the detection pattern on the 1st side surface is the largest (i.e., the large pattern), the detection pattern on the 2nd side surface is the second largest (i.e., the medium pattern), and the detection pattern on the 3rd side surface is the smallest (i.e., the small pattern). In this way, by rotating the rotating body 3 clockwise, the large pattern, the medium pattern, and the small pattern can be sequentially shown to the person being tested in the order from large to small, which is more convenient for the operation during the visual function examination.

[0045] In one embodiment, the binocular visual function quick measurement device further includes a connecting seat 4 disposed between the handle 1 and the rotating body 3. The lower end of the connecting seat 4 is fixedly connected to the upper end of the handle 1. The central shaft 2 is inserted and fixed on the connecting seat 4. The upper end of the connecting seat 4 is in a triangular shape adapted to the lower end surface of the rotating body 3. The connection between the handle 1 and the rotating body 3 is transitioned through the connecting seat 4, which is convenient for the overall design of the device's appearance and makes the whole device more beautiful in appearance.

[0046] In one embodiment, the binocular visual function quick measurement device further includes a driving mechanism 5 and a changeover switch 6;

[0047] The connecting seat 4 includes a seat body 41 and a top plate 42. The top plate 42 is fixedly disposed on the top of the seat body 41 through screws. The middle part of the top plate 42 has a receiving cavity 421. The driving mechanism 5 includes a motor 51, a driving gear 52, and a driven gear 53 disposed in the receiving cavity 421. The lower end of the central shaft 2 is inserted and fixed in the receiving cavity 421 of the top plate 42. The output shaft of the motor 51 is fixedly connected to the driving gear 52. The driving gear 52 meshes with the driven gear 53. The driven gear 53 is sleeved on the central shaft 2 and can rotate around the central shaft 2. The upper end surface of the driven gear 53 is fixedly connected to the lower end surface of the rotating body 3;

[0048] The changeover switch 6 is arranged on the seat body 41, and the changeover switch 6 is electrically connected to the motor 51. When the changeover switch 6 is pressed, the motor 51 rotates a preset angle, so that the side surface of the rotating body 3 facing the person to be measured is switched from the current side surface to the next side surface.

[0049] In this embodiment, a driving mechanism 5 is constituted by arranging the motor 51, the driving gear 52 and the driven gear 53 to drive the rotating body 3 to rotate automatically, and the start and stop of the motor 51 are controlled by the changeover switch 6. When the changeover switch 6 is pressed, the motor 51 rotates a preset angle, and thus the rotating body 3 is driven to rotate successively through the driving gear 52 and the driven gear 53, so that the side surface of the rotating body 3 facing the person to be measured is switched from the current side surface to the next side surface, realizing the switching of different side surfaces on the rotating body 3, that is, realizing the switching of the detection patterns, and the operation is more convenient.

[0050] Specifically, in this embodiment, the rotating body 3 can be set as a regular triangular prism. Thus, when it is necessary to rotate the rotating body 3 to switch the detection pattern, the changeover switch 6 is pressed, and the rotating body 3 rotates 120 degrees in the set rotation direction, and the side surface of the rotating body 3 facing the person to be measured can be automatically switched from the current side surface to the next side surface.

[0051] In one embodiment, the seat body 41 and the handle 1 are integrally formed. With such a setting, the reliability of the connection between the handle 1 and the connecting seat 4 is ensured, and the overall strength of the device is improved.

[0052] In one embodiment, the rotating body 3 includes a triangular prism frame and three pattern plates 32. The three pattern plates 32 are respectively detachably mounted on the three side surfaces of the triangular prism frame, and the detection patterns are arranged on the pattern plates 32. With such a setting, it is convenient to replace the pattern plates 32 as needed, that is, it is convenient to replace the detection patterns as needed. Specifically, the pattern plates 32 can be detachably connected to the triangular prism frame 31 by means of screws or buckles.

[0053] In one embodiment, the pattern plate 32 is made of a light-transmitting or semi-light-transmitting material plate, and opaque coatings are applied to other areas of the outer surface of the pattern plate 32 except the detection patterns. In this way, when a light source is arranged inside the rotating body 3 for supplementary lighting, the light can only pass through the detection patterns, and the detection patterns can be more prominent, better ensuring the detection effect.

[0054] In one embodiment, the binocular vision function rapid detection device further includes a supplementary light lamp 7 and a supplementary light control switch 8. The supplementary light lamp 7 is arranged on the central axis 2 along the axial direction of the central axis 2. By arranging the supplementary light lamp 7 for supplementary lighting, visual function inspection can also be carried out in an environment with relatively dim light, so that the binocular vision function rapid detection device can be applicable to both bright environments and dark environments, effectively improving the applicability of the device.

[0055] In one embodiment, the binocular vision function quick measurement device further includes a base 9, and the handle 1 is inserted into the base 9. By providing the base 9, the handle 1 can be inserted into the base 9. When in use, it is not necessary for the tester to hold it all the time, which reduces the work intensity of the tester and also ensures that the device does not shake during the detection process. When not in use, it is more convenient to place the whole device stably.

[0056] Those skilled in the art can understand that although some embodiments herein include certain features included in other embodiments rather than other features, the combination of features of different embodiments means that it is within the scope of the present application and forms different embodiments. In some instances, well-known methods, structures, and technologies are not shown in detail so as not to obscure the understanding of this specification.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered by the scope of the claims and the specification of the present application.
