Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to an ophthalmic vision testing device. Background Technology

[0002] Traditional ophthalmic vision tests that rely on patients manually occluding their eyes face numerous challenges. Although medical staff patiently explain the importance of the test and the correct occlusion method, human interference is still difficult to completely eliminate in practice. This is especially true for children, who are often curious but have limited patience and concentration; they are easily distracted or uncooperative during the test, which undoubtedly reduces the accuracy and reliability of the vision test results.

[0003] Furthermore, manual occlusion introduces inconsistencies in the testing environment, primarily in the position and angle of the occlusion shield, as well as the stability of the patient's hand, further exacerbating the variability of test results. Some patients may experience hand tremors due to tension or anxiety during the test, making it difficult for the occlusion shield to stably cover one eye, which poses an additional threat to the accuracy of the test results.

[0004] At the same time, we must also note that there are significant differences in facial size and shape among individuals, which places higher demands on the adaptability of vision testing devices. Ensuring that the device fits snugly against the subject's face during testing is a crucial prerequisite for guaranteeing both accuracy and comfort. Utility Model Content

[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0026] An ophthalmic vision testing device according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0027] like Figures 1-5 As shown, an ophthalmic vision testing device according to an embodiment of the present invention includes a support 1, two actuating devices 2, two shielding plates 3, and an adjustment device 4. Each of the two actuating devices 2 includes an actuating plate 21 and a connecting component 22. The actuating plate 21 is rotatably disposed on one side of the support 1, and the connecting component 22 is rotatably disposed on one side of the support 1, with one end of the connecting component 22 connected to one end of the actuating plate 21. The two shielding plates 3 are rotatably disposed on the support 1, with one end of each shielding plate 3 connected to the other end of the connecting component 22. The adjustment device 4 includes an adjustment component 41 and a movable component 42. The adjustment component 41 is slidably disposed at the center of the head of the support 1, and the movable component 42 is movably disposed on the support 1 and is movably connected to the adjustment component 41.

[0028] It can be understood that bracket 1 is the supporting structure of the entire device, used to fix and support other components.

[0029] The toggle device 2 is used to control the rotation of the shield 3, thereby blocking and releasing the subject's line of sight.

[0030] The toggle plate 21 is rotatably mounted on one side of the bracket 1, and the user can operate it by manually toggling it.

[0031] The connecting component 22 is also rotatably mounted on one side of the bracket 1. One end of it is connected to one end of the toggle plate 21, and the other end is connected to the baffle plate 3, so as to realize the linkage between the toggle plate 21 and the baffle plate 3.

[0032] The obstruction plate 3 is used to block the subject's line of sight in order to conduct a monocular visual acuity test.

[0033] The baffles 3 are rotatably mounted on the bracket 1 and connected to the toggle device 2 via the connecting assembly 22, so that they can rotate under the operation of the toggle device 2.

[0034] The adjustment component 41 is slidably disposed at the center of the head of the bracket 1 for position adjustment along the length of the bracket 1.

[0035] The movable component 42 is movably mounted on the bracket 1 and is movably connected to the adjustment component 41. The movable component 42 is used to fix the adjusted position.

[0036] Through the cooperation of the aforementioned components, the ophthalmic visual acuity testing device of this embodiment can accurately test the visual acuity of the test subject. The user can manually operate the toggle device 2 to control the rotation of the obstruction plate 3, thereby blocking or releasing the test subject's line of sight. Simultaneously, the addition of the adjustment device 4 allows for a close fit to the facial dimensions of different individuals, improving testing comfort and accuracy.

[0037] In one embodiment of this utility model, such as Figure 4 As shown, the connecting assembly 22 includes a fixed rod 221, a rotating block 222, a first connecting rod 223, and a second connecting rod 224. The fixed rod 221 is disposed on one side of the bracket 1. One end of the rotating block 222 is movably connected to one end of the fixed rod 221. One end of the first connecting rod 223 is movably connected to the other end of the toggle plate 21, and the other end of the first connecting rod 223 is movably connected to one end of the other side of the rotating block 222. One end of the second connecting rod 224 is connected to one end of the rotating block 222, and the other end is connected to one end of each of the two baffle plates 3.

[0038] It can be understood that the fixing rod 221 is the fixing part of the connecting assembly 22. It is set on one side of the bracket 1 and provides stable support for the entire connecting assembly 22.

[0039] One end of the fixed rod 221 is connected to the bracket 1, and the other end is movably connected to the rotating block 222, so that the rotating block 222 can rotate freely on the fixed rod 221.

[0040] The rotating block 222 is a key component in the connecting assembly 22. One end of it is movably connected to the fixed rod 221, allowing the rotating block 222 to rotate around the fixed rod 221.

[0041] One end of the other side of the rotating block 222 is movably connected to the first connecting rod 223, and the other end is connected to one end of the second connecting rod 224. This design allows the rotating block 222 to produce a corresponding rotational movement when it is acted upon by the actuating plate 21 or the second connecting rod 224.

[0042] One end of the first connecting rod 223 is movably connected to the other end of the toggle plate 21, and the other end is movably connected to one end of the other side of the rotating block 222.

[0043] When the user manually moves the toggle plate 21, the first connecting rod 223 will rotate accordingly, and through its active connection with the rotating block 222, the rotation action will be transmitted to the rotating block 222.

[0044] One end of the second connecting rod 224 is connected to one end of the rotating block 222, and the other end is connected to one end of each of the two baffles 3.

[0045] When the rotating block 222 is subjected to the rotational action of the first connecting rod 223, the second connecting rod 224 will generate a corresponding rotational action, and through the connection with the baffle plate 3, the rotational action will be transmitted to the baffle plate 3, thereby realizing the rotation of the baffle plate 3.

[0046] With this design, when the user manually moves the toggle plate 21, the first connecting rod 223 drives the rotating block 222 to rotate, which in turn transmits the rotational motion to the blocking plate 3 via the second connecting rod 224, thus enabling the blocking plate 3 to rotate. This design is not only simple in structure and easy to implement, but also effectively transmits the rotational motion of the toggle plate 21 to the blocking plate 3, thereby achieving the blocking and release of the subject's line of sight.

[0047] In one embodiment of this utility model, such as Figure 5 As shown, the adjustment assembly 41 includes an adjustment rod 411, a sliding sleeve 412, a limiting plate 413, and a slot 414. The adjustment rod 411 is slidably disposed inside the center of the head of the bracket 1, and one end of the adjustment rod 411 is connected to one end of the interior of the bracket 1. The sliding sleeve 412 is disposed on the other side inside the bracket 1, and the adjustment rod 411 is slidably disposed inside the sliding sleeve 412. The limiting plate 413 is disposed at the other end of the adjustment rod 411, and the slots 414 are equidistantly disposed on the adjustment rod 411.

[0048] It is understood that the adjusting rod 411 is the core component of the entire adjusting assembly 41, and it is slidably disposed inside the center of the head of the bracket 1. This design allows the adjusting rod 411 to slide freely inside the bracket 1, thereby achieving lateral adjustment of the device. One end of the adjusting rod 411 is connected to one end inside the bracket 1, and this connection is usually firm and stable to ensure that the adjusting rod 411 will not fall off or wobble during adjustment.

[0049] The sliding sleeve 412 is disposed on the other side inside the bracket 1, corresponding to the adjusting rod 411. The sliding sleeve 412 provides a smooth and stable sliding track, allowing the adjusting rod 411 to slide smoothly inside it.

[0050] The limiting plate 413 is located at the other end of the adjusting rod 411, that is, the end away from the inside of the bracket 1. The main function of the limiting plate 413 is to prevent the adjusting rod 411 from sliding out excessively during the sliding process, thereby ensuring the safety of the device during the adjustment process.

[0051] By setting the limit plate 413, we can effectively control the sliding range of the adjusting rod 411 and prevent it from exceeding the preset safety area.

[0052] The slots 414 are equidistantly arranged on the adjusting rod 411. These slots are used to cooperate with the locking mechanism inside the bracket 1 to realize the locking function after adjustment.

[0053] In practical applications, when a user needs to adjust the width of device 4 to accommodate different facial shapes, they can manually operate the adjustment rod 411, allowing it to slide inside the bracket 1. Because the sliding sleeve 412 provides a stable sliding track, the adjustment rod 411 can smoothly slide to the desired position. Once the desired width is reached, the user can use the locking mechanism inside the bracket 1, in conjunction with the slot 414, to lock the adjustment rod 411 in the desired position. In this way, the overall width of the device is adjusted to meet the facial shape needs of different groups.

[0054] In one embodiment of this utility model, such as Figure 5 As shown, the movable component 42 includes a movable rod 421 and a spring 422. The movable rod 421 is slidably disposed on the top side of the bracket 1, and the other end of the movable rod 421 is movably connected to the slot 414. The spring 422 is disposed inside the bracket 1, and one end of the spring 422 is connected to the movable rod 421.

[0055] It is understood that the other end of the movable rod 421 is movably connected to the slot 414. "Movably connected" here means that the movable rod 421 can be connected to the slot 414 via a snap-fit ​​mechanism, but can also be disengaged when needed. This design allows the movable rod 421 to selectively engage with the slot 414 as needed, thereby locking or releasing the adjusting rod 411.

[0056] Spring 422 is installed inside bracket 1, and one end of it is connected to movable rod 421. The main function of spring 422 is to provide elastic force so that movable rod 421 can maintain a certain position or state when no external force is applied.

[0057] When the user needs to adjust the position of the movable rod 421, an external force can be applied to overcome the elastic force of the spring 422, causing the movable rod 421 to slide. When the external force disappears, the elastic force of the spring 422 will cause the movable rod 421 to return to its original position or state. This design not only increases the flexibility of the device but also allows the movable rod 421 to remain stable when no external force is applied.

[0058] In practical applications, when the user needs to fine-tune the device, this can be achieved by operating the movable rod 421. Specifically, the user can pull the movable rod 421 to slide it along the top of the bracket 1. Since the other end of the movable rod 421 is movably connected to the slot 414, when the user adjusts the position of the movable rod 421, it can selectively engage or disengage with the slot 414.

[0059] When the movable rod 421 engages with the slot 414, it locks the adjusting rod 411 in the desired position, ensuring the device remains stable. When the user needs to adjust the width of the device, they can operate the movable rod 421 to disengage it from the slot 414 and then slide the adjusting rod 411 to the desired position. Finally, the movable rod 421 is operated again to engage with the slot 414, thus completing the fine-tuning process.

[0060] In one embodiment of this utility model, such as Figure 2 As shown, the two ends of the bracket 1 are respectively hinged with mirror temples 11.

[0061] It is understandable that, in practical applications, users can adjust the bracket 1 and temple 11 according to their head shape and size, as well as the needs of vision testing. Specifically, users can adjust the angle and position of the temple 11 by rotating it to better secure the device to their head.

[0062] Detailed usage instructions:

[0063] I. Equipment Preparation

[0064] Ensure that all components of the ophthalmic visual acuity testing device (stand 1, toggle device 2, shield 3, adjustment device 4) are intact and in normal working order.

[0065] Check whether the temples 11 at both ends of the bracket 1 are firmly hinged to the bracket 1, and ensure that the temples 11 can rotate flexibly and adapt to different users' head shapes.

[0066] II. Wearing Device

[0067] The user wears the eye test vision device on their head via the temple 11, and adjusts its angle and position by rotating the temple 11 to ensure that the device fits the head securely and comfortably.

[0068] As the supporting structure of the entire device, bracket 1 should ensure that it is firmly supported above the user's nose bridge for vision testing.

[0069] III. Width of Adjustment Device

[0070] Users can adjust the width of the device by manually operating the adjustment lever 411 in the adjustment component 41 according to their face shape.

[0071] The adjustment rod 411 slides inside the center of the head of the bracket 1. The user can change its position by sliding the adjustment rod 411 until the width of the device is suitable for the user's face shape.

[0072] Once adjusted to the desired position, the user can use the movable lever 421 in the movable component 42 to lock the adjusting lever 411 in the desired position. The movable lever 421 is movably connected to the slot 414, and the user can lock the adjusting lever 411 by operating the movable lever 421 to engage with the slot 414.

[0073] IV. Conduct a vision test

[0074] Users can control the rotation of the shield 3 by manually operating the toggle device 2 to test the eyes they need.

[0075] The toggle plate 21 is rotatably mounted on one side of the bracket 1, and the user operates the connecting assembly 22 by manually toggling the toggle plate 21.

[0076] The connecting assembly 22 includes a fixed rod 221, a rotating block 222, a first connecting rod 223, and a second connecting rod 224. When the user moves the toggle plate 21, the first connecting rod 223 drives the rotating block 222 to rotate, and then transmits the rotational action to the baffle plate 3 through the second connecting rod 224, thereby realizing the rotation of the baffle plate 3.

[0077] When the obstruction panel 3 is rotated to the position that blocks the view, the user can begin to observe the vision test chart to conduct a vision test.

[0078] V. Eye Switching Test

[0079] After completing the vision test for one eye, the user can control the rotation of the shield 3 by operating the toggle device 2 again to release the line of sight, and at the same time switch the other shield 3 to the other eye for testing.

[0080] Repeat the steps in step four until the vision test for both eyes is completed.

[0081] In summary, the ophthalmic vision testing device of this utility model allows users to easily cover and expose their eyes through a simple dial operation, improving the efficiency of vision testing. The design of the adjustable stretching mechanism enables the device to closely fit the facial size and shape of different individuals, improving the comfort and accuracy of the test. This adaptive design helps to meet the needs of people of different ages and facial features.
