Description

Technical Field

[0001] The utility model relates to the field of glasses detection, in particular to strabismus detection glasses. Background Art

[0002] Strabismus detection is an important part of ophthalmic diagnosis. Scientific methods and equipment can be used to accurately determine the type and degree of strabismus.

[0003] Existing methods for detecting strabismus generally rely on observation or instrumental testing. A cover-and-uncover method is generally used to detect whether the subject has strabismus. Specifically, the subject holds a covering object and blocks one eye with it. The covering alternates with the other to observe the movement of the eyeball. If the eyeball moves, strabismus is present. This method can detect whether the subject has strabismus and determine the type of strabismus. A Maddox rod lens can also be used to detect the direction of strabismus. By covering one eye with the Maddox rod lens, the direction of strabismus can be determined based on the observation and detection structure of both eyes.

[0004] However, when judging by the combination of the above methods and devices, it is difficult to ensure the accuracy of the test results due to factors such as manual operation. When the subject holds an occluding object to cover one eye, it is difficult to ensure that the eye on that side can be completely covered, and thus the test results of one eye are difficult to avoid interference from the other eye. At the same time, the test process requires holding the occluding object or Maddox rod lens, and the subject may reduce cooperation due to fatigue or discomfort, affecting the test results. In addition, holding the occluding object or lens for a long time will cause hand muscle fatigue.

[0005] In summary, the present invention provides strabismus detection glasses. Utility Model Content

[0031] A frame 1 and two fogged lenses 2, wherein the two fogged lenses 2 are fixedly arranged inside the frame 1. The fogged lenses 2 include two glass layers and a liquid crystal film. The two glass layers are symmetrically arranged relative to the liquid crystal film. A conductive column (not shown) is fixedly connected to the liquid crystal film, and the conductive column (not shown) is electrically connected to an external power supply.

[0032] It should be noted that when the fogging lens 2 is powered on, the liquid crystal molecules change state, and the interior of the lens becomes foggy, shielding the eye on that side;

[0033] The surface of the frame 1 is detachably connected to a telescopic rod 3, the end of the telescopic rod 3 is rotatably connected to a sight mark 24, and the two fogged lenses 2 are symmetrically arranged relative to the sight mark 24;

[0034] A rotating prism 4 is detachably mounted on the surface of the lens frame 1 . Two placement grooves 25 are provided on the surface of the lens frame 1 . The placement grooves 25 can accommodate Maddox rod lenses.

[0035] It should be noted that the rotating prism 4 is a Risley rotating prism, which is composed of two rotatable prisms. The prism power and base direction are adjusted by rotation. When used in conjunction with a Maddox rod lens, the base direction (BI, BO, BU, BD) of the rotating prism 4 is adjusted according to the strabismus direction (esotropy, exotropy, hypertropy, hypotropy), gradually neutralizing the strabismus angle. The strabismus angle can be directly obtained by the numerical value on the surface of the rotating prism 4. A placement groove 25 is provided on the surface of the frame 1. The Maddox rod lens is inserted into the frame 1 through the placement groove 25, and its two surfaces contact the edges of the placement groove 25. The placement groove 25 restricts the Maddox rod lens from being separated from the frame 1, and the edge of the frame 1 is in contact with the edge of the Maddox rod lens. The frame 1 supports the Maddox rod lens, preventing the Maddox rod lens from shifting during the detection process.

[0036] The telescopic belt 5 is fixedly arranged at both ends of the frame 1;

[0037] In summary, the strabismus detection glasses provided by the embodiment of the present invention include a frame 1 with a fogged lens 2. When the fogged lens 2 is powered on, the visual state of the lens on that side can be controlled to achieve occlusion, thereby avoiding the influence of incomplete occlusion on the result during detection, and retractable belts 5 are provided at both ends of the frame 1.

[0038] like Figure 2 As shown, in some specific implementation schemes, the retractable belt 5 includes a fixing belt and a connecting belt, which are rotatably arranged at both ends of the frame 1 respectively, and a through groove 26 for the connecting belt to pass through is provided on the surface of the fixing belt, and a plurality of fixing grooves 6 are provided on the surface of the connecting belt, and a fixed shaft 7 adapted to the fixing groove 6 is provided on the surface of the fixing belt; after the connecting belt passes through the through groove 26, the space between the fixing belt, the connecting belt and the frame 1 can be changed through the contact between the fixing shaft 7 and the fixing grooves 6 at different positions, so that it is suitable for wearing by different subjects.

[0039] like Figure 4As shown, in some specific embodiments, the surface of the frame 1 is provided with a groove for embedding the telescopic rod 3, and the two opposite side walls of the groove are provided with connecting grooves 8. The two side walls of the telescopic rod 3 are slidably connected to two connecting posts 9 adapted to the connecting grooves 8. A connecting spring 10 is provided inside the telescopic rod 3, and the two ends of the connecting spring 10 are respectively fixedly connected to the two connecting posts 9; by compressing the connecting spring 10, the two connecting posts 9 are slid into the interior of the telescopic rod 3, prompting the connecting posts 9 to disengage from the connecting grooves 8, thereby prompting the telescopic rod 3 to be disassembled from the frame 1, so that the frame 1 and the telescopic rod 3 are conveniently stored;

[0040] Furthermore, in order to facilitate the compression of the connecting spring 10, a lever can be set on the upper surface of the two connecting columns 9. By squeezing the two levers and making the two levers move towards each other, the two connecting columns 9 can squeeze the connecting spring 10 and slide into the inside of the telescopic rod 3.

[0041] like Figure 4 、 Figure 5 As shown, in some specific embodiments, the telescopic rod 3 includes a main rod and a mobile rod, the mobile rod is slidably arranged on the side wall of the main rod, and the cylindrical groove 27 is opened on the side wall of the main rod, the connecting column 9 is slidably arranged in the cylindrical groove 27, the sight mark 24 is rotatably arranged on the end of the mobile rod, the surface of the main rod is provided with a sliding groove 11, the sliding groove 11 is adapted to the mobile rod, and a limiting component is provided between the mobile rod and the sliding groove 11; when the telescopic rod 3 needs to be stored, the mobile rod can be completely slid into the sliding groove 11, the sliding groove 11 can be used to store the telescopic rod 3, and the position of the mobile rod inside the main rod can be adjusted according to the condition of the subject, thereby changing the distance between the sight mark 24 and the frame 1;

[0042] In a further embodiment, the limiting assembly includes a limiting column 12 that rotates and penetrates the main rod, and a plurality of limiting grooves 13 are opened on one side of the moving rod close to the limiting column 12, and the limiting column 12 is adapted to the limiting grooves 13.

[0043] like Figure 2 and Figure 3 As shown, in some specific embodiments, the surface of the rotating prism 4 is rotatably connected to an insertion column 14, and a fixing component for limiting the position of the insertion column 14 is provided between the insertion column 14 and the frame 1;

[0044] like Figure 3 、 Figure 6As shown, in a further embodiment, the frame 1 is provided with an assembly groove for mounting the rotating prism 4, the fixing assembly includes a fixing column 15 slidably arranged in the assembly groove, a fixing spring 16 is fixedly connected between the fixing column 15 and the bottom of the assembly groove, a plurality of radial grooves 29 are provided on the side wall of the assembly groove, the radial grooves 29 are communicated with the assembly groove, a compression spring 28 is provided in the radial groove 29, one end of the compression spring 28 is fixedly connected to the bottom of the radial groove 29, and the other end is fixedly connected to a fixing rod 17 in contact with the fixing column 15, the frame 1 is threadedly connected to an operating rod 18, the operating rod 18 passes through the frame 1 and extends into the radial groove 29; in the initial state, the fixing rod 1 7 will be squeezed back into the radial groove 29 by the fixing post 15 under the action of the fixing spring 16. After the insertion post 14 on the surface of the rotating prism 4 is aligned and in contact with the fixing post 15, the rotating prism 4 is pressed toward the bottom of the assembly groove, causing the insertion post 14 to squeeze the fixing post 15. The fixing rod 17 will move along the oblique groove 19 under the elastic force of the compression spring 28 and contact the surface of the insertion post 14. Then the operating rod 18 is rotated, and the end of the operating rod 18 abuts against the fixing rod 17 to limit the position of the fixing rod 17, ensuring that the insertion post 14 and the frame 1 are fixed in position. The insertion post 14 is limited in two mutually perpendicular directions by the fixing rod 17 and the fixing post 15, so that the rotating prism 4 can be stably installed on the frame 1.

[0045] In the initial state, the operating rod 18 is rotated outward of the frame 1 for a certain distance, and the fixing rod 17 is squeezed back into the radial groove 29 by the fixing column 15 under the action of the fixing spring 16. The position of the fixing rod 17 can be adjusted by rotating the operating rod 18, thereby adjusting the position of the fixing column 15.

[0046] Preferably, the cross section of the insertion column 14 is in the shape of an "I"; the surface of the fixing rod 17 that abuts the insertion column 14 is configured as a groove; the protrusion of the insertion column 14 on the side close to the bottom of the assembly groove is adapted to the groove portion of the fixing rod 17; the insertion column 14 is configured as an "I" shape so that a region with a smaller diameter exists on its surface for clamping the rotating prism 4 and a side wall of the fixing rod 17; a side wall of the fixing rod 17 abuts against the rotating prism 4 in this region, thereby limiting the insertion column 14 from sliding away from the frame 1;

[0047] like Figure 3 As shown, in a further implementation scheme, a plurality of oblique grooves 19 corresponding to the fixing rod 17 are provided on the surface of the fixing column 15, and the end face of one side of the fixing rod 17 contacts the oblique groove 19, and the end face of the side of the fixing rod 17 in contact with the oblique groove 19 is also an inclined surface, which facilitates the transmission of the lateral movement of the fixing column 15 into the longitudinal movement of the fixing rod 17.

[0048] In some specific embodiments, a light bulb 20 and a magnetic ring 21 are fixedly connected to the surface of the sight mark 24, the light bulb 20 is electrically connected to an external power supply, and the light bulb 20 is located inside the magnetic ring 21; the light bulb 20 and the magnetic ring 21 are set on the surface of the sight mark 24, and then the sight mark 24 can be rotated to change the position of the sight mark 24 to the light source, and then cooperate with the Maddox rod lens to detect the strabismus angle, and at the same time, the magnetic ring 21 is set to selectively adsorb tools such as a camera to record the changing state of the eyeball.

[0049] In a further implementation scheme, the end of the sight mark 24 is fixedly connected to a rotating column 22, and two limiting grooves are provided on the surface of the rotating column 22. The end of the movable rod is fixedly connected to two limiting rods 23, and the limiting grooves are adapted to the limiting rods 23. By the existence of the limiting rods 23, the rotation direction and rotation angle of the sight mark 24 can be limited. When the sight mark 24 is rotated until the limiting groove contacts the limiting rods 23, the light bulb 20 can be flipped to face the frame 1 to avoid the light bulb 20 from rotating too much, resulting in light offset, and difficulty in forming a circle with clear boundaries in the subject's line of sight.

[0050] The working principle of this utility model:

[0051] When using the device, first press the two connecting posts 9 on the telescopic rod 3. The telescopic rod 3 and the frame 1 are fixed by clamping the connecting posts 9 and the connecting grooves 8. Then fix the telescopic belt 5 to the head of the person being tested so that the eyeballs being tested are covered by the fogged lens 2. Rotate the limiting post 12 to disengage the limiting post 12 from the limiting groove 13. Pull the moving rod and adjust the position of the moving rod. When the position is appropriate, rotate the limiting post 12 in the opposite direction so that the limiting post 12 is inserted into the corresponding limiting groove 13 to fix the moving rod. The fogging lens 2 is energized in turn to cover one side of the eye and observe whether the subject's eyeball moves; if the eyeball moves, a rotating prism 4 is placed on the surface of the frame 1 where the other eyeball does not move. After the insertion column 14 on the surface of the rotating prism 4 is aligned and in contact with the fixed column 15, the rotating prism 4 is pressed toward the position of the frame 1, causing the insertion column 14 to squeeze the fixed column 15, and the fixed column 15 slides to the side away from the sight mark 24. Under the action of the compression spring 28 and the oblique groove 19, the distance between the several fixed rods 17 on the surface of the fixed column 15 is reduced. Due to compression, the fixed rod 17 then contacts the surface of the insertion column 14, and then the operating rod 18 is rotated. The side end is connected to the frame 1 through a thread, and the other side end of the operating rod 18 is rotated to fit with the fixed rod 17, limiting the position of the fixed rod 17, ensuring that the insertion column 14 is fixed to the frame 1, and the rotating prism 4 is overlapped with the eyeball on that side, and the fogging lenses 2 on both sides of the frame 1 are controlled to fog alternately, and observe whether the subject's eyeball moves. If the subject's eyeball moves, the base direction of the rotating prism 4 is adjusted according to the direction of eyeball movement, and then the degree of the rotating prism 4 is adjusted, and the fogging lenses 2 are controlled to fog alternately, and the changes in the subject's eyeball are observed. If the eyeball moves, the degree of the rotating prism 4 is continued to be adjusted until the subject's eyeball does not move, and the current surface value of the rotating prism 4 is recorded.

[0052] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
