Description

Technical Field

[0001] This utility model belongs to the field of ophthalmic examination technology, and in particular relates to a dry eye detector for ophthalmic examination. Background Technology

[0002] Ophthalmological examinations are an important means of maintaining visual health. Through different types of examinations, various eye diseases can be detected and diagnosed in a timely manner. Among ophthalmological examinations, a dry eye tester is a device specifically used to diagnose dry eye syndrome, a common eye disease. Its main symptoms include dry eyes, pain, photophobia, and tearing. In severe cases, it can lead to decreased vision. During the examination, the patient first places their chin on a support. The support ensures that the patient's head remains fixed during the examination, preventing head movement from interfering with the measurement results. The dry eye tester then measures indicators such as tear secretion, tear film stability, and ocular surface condition to provide important evidence for the diagnosis of dry eye syndrome.

[0003] The problem with existing technology is that if the tray that the patient has been in contact with is not cleaned when the dry eye detector is performing dry eye testing, the tray, as a part that comes into direct contact with the patient's skin, may accumulate dust, dirt, sebum and other impurities, affecting the hygiene of the detector. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a dry eye detector for ophthalmic examination, which has the advantage of allowing for quick disassembly of the tray of the dry eye detector for thorough cleaning and hygiene maintenance. This solves the problem that if the tray, which is in direct contact with the patient's skin, is not cleaned during dry eye testing, dust, dirt, sebum and other impurities may accumulate on the tray, affecting the hygiene of the detector.

[0005] This utility model is implemented as follows: a dry eye detector for ophthalmic examination includes a base, a support, a bracket, a connecting groove, and an assembly structure. A support arm is fixedly connected to the right side of the top of the base, and a movable seat is slidably connected to the left side of the top of the base. The detector is fixedly connected to the top of the movable seat. The support is fixedly connected to the top of the support arm. A movable groove is formed on the right side of the support. A connecting groove is formed on the top of the support. A positioning block is inserted into the top of the connecting groove. Positioning grooves are formed on the front and rear sides of the positioning block. A bracket is fixedly connected to the top of the positioning block. A connecting groove is formed on the right side of the support. Movable rods are fixedly connected to the front and rear sides of the inner wall of the connecting groove. An assembly structure is provided on the inner wall of the connecting groove.

[0006] In a preferred embodiment of this utility model, the assembly structure includes a displacement block disposed on the right side of the support base. The outer surface of the displacement block is slidably connected to the inner wall of the moving groove. A push button is fixedly connected to the right side of the displacement block, and a displacement arm is fixedly connected to the left side of the displacement block. By setting the displacement block, when the push button is pressed downward, it can drive the displacement block to slide downward in the moving groove, thereby driving the displacement arm to move synchronously.

[0007] In a preferred embodiment of this utility model, the displacement arm is disposed on the inner wall of the connecting groove, and displacement rods are fixedly connected to the front and rear ends of the left side of the displacement arm. Two driven arms are respectively disposed on the side of the two displacement rods that are close to each other. By setting the displacement arm, the displacement arm can be driven by the displacement block to move downward in the connecting groove, and at the same time drive the two displacement rods to move synchronously. Thus, the two moving rods move and drive the two driven arms to rotate.

[0008] In a preferred embodiment of this invention, the two movable arms are respectively positioned front and rear on the inner wall of the connecting groove. The ends of the two movable arms that are close to each other are rotatably connected to the left and right sides of the inner wall of the connecting groove via rotating shafts. The ends of the two movable arms that are far apart from each other are respectively attached to the two moving rods. The ends of the two movable arms that are close to each other are respectively fixedly connected to follower arms. By setting the movable arms, the two moving rods can press the surfaces of the two movable arms respectively while moving downwards, causing the two movable arms to rotate relative to each other. Thus, when the two movable arms rotate, they respectively drive the two follower arms to rotate in a following manner.

[0009] In a preferred embodiment of this invention, the bottom of the two follower arms near the driven arms is fixedly connected to the top of the two driven arms at their respective ends. The top of each of the two follower arms is provided with a slot, and the sides of the tops of the two follower arms that are far apart from each other are provided with a fixing arm. By providing the follower arms, the two follower arms can stagger the moving rod through the slots during rotation and push the two fixing arms, thereby driving the two fixing arms to move away.

[0010] In a preferred embodiment of this invention, the two fixing arms are slidably connected to the outer surface of the moving rod at their midpoints. The sides of the two fixing arms that are close to each other are respectively attached to the two following arms. The sides of the two fixing arms that are far apart from each other are respectively fixedly connected to fixing springs. Both fixing springs are sleeved on the outer surface of the moving rod. The ends of the two fixing springs that are far apart from each other are respectively fixedly connected to the inner wall of the connecting groove. The tops of the two fixing arms are respectively fixedly connected to fixing blocks. By setting the fixing arms, the two fixing arms can be pushed by the following arms respectively, slide away on the moving rod, and compress the two fixing springs respectively. The sliding of the two fixing arms then drives the two fixing blocks to move away respectively.

[0011] As a preferred embodiment of this utility model, the two fixing blocks are respectively fixedly connected to the top of the two fixing arms on the side that is close to each other. The ends of the two fixing blocks that are close to each other are respectively inserted into the inner wall of the positioning groove. By setting the fixing blocks, the fixing blocks can be disengaged from the positioning groove when they move away, thereby releasing the fixing of the positioning blocks and thus releasing the fixed connection between the bracket and the support.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a base, support seat, bracket, connecting groove and assembly structure, achieves the effect of solving the problem that in existing dry eye detectors, if the bracket that has been in contact with the patient is not cleaned during dry eye detection, the bracket, as a part that comes into direct contact with the patient's skin, may accumulate dust, dirt, sebum and other impurities, affecting the hygiene of the detector.

[0014] 2. This utility model, by setting up a support base and a bracket, enables the connecting groove and the assembly structure to work together. The assembly structure fixes the positioning block inserted into the connecting groove, thereby installing the bracket on the support base. This provides support for the patient, allowing for stable testing. The bracket can also be disassembled to thoroughly clean the dirt accumulated on its surface. Timely cleaning effectively removes accumulated dust, grime, sebum, and other impurities, ensuring the hygiene of the testing instrument. Attached Figure Description

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown in the figure, the dry eye detector for ophthalmic examination provided by this utility model includes a base 1, a support 2, a bracket 3, a connecting groove 4, and an assembly structure 5. A support arm 101 is fixedly connected to the right side of the top of the base 1, and a movable seat 102 is slidably connected to the left side of the top of the base 1. A detector 103 is fixedly connected to the top of the movable seat 102. The support 2 is fixedly connected to the top of the support arm 101. A movable groove 7 is opened on the right side of the support 2. A connecting groove 4 is opened on the top of the support 2. A positioning block 6 is inserted into the top of the connecting groove 4. Positioning grooves 601 are opened on the front and rear sides of the positioning block 6. The bracket 3 is fixedly connected to the top of the positioning block 6. A moving rod 401 is fixedly connected to the front and rear sides of the inner wall of the connecting groove 4. An assembly structure 5 is provided on the inner wall of the connecting groove 4.

[0023] refer to Figure 3 and Figure 4 The assembly structure 5 includes a displacement block 8, which is located on the right side of the support base 2. The outer surface of the displacement block 8 is slidably connected to the inner wall of the moving groove 7. A push button 9 is fixedly connected to the right side of the displacement block 8, and a displacement arm 10 is fixedly connected to the left side of the displacement block 8.

[0024] The above scheme is adopted: by setting the displacement block 8, when the button 9 is pressed down, it can drive the displacement block 8 to slide down in the moving groove 7, and the sliding displacement block 8 can drive the displacement arm 10 to move synchronously.

[0025] refer to Figure 4 The displacement arm 10 is set on the inner wall of the connecting groove 4. The front and rear ends of the left side of the displacement arm 10 are respectively fixedly connected to the displacement rods 11. Two driven arms 12 are respectively set on the side of the two displacement rods 11 that are close to each other.

[0026] The above scheme is adopted: by setting the displacement arm 10, the displacement arm 10 can be driven by the displacement block 8 to move downward in the connecting groove 4, and at the same time drive the two displacement rods 11 to move synchronously, so that the two moving rods 401 move and drive the two driven arms 12 to rotate.

[0027] refer to Figure 4Two driven arms 12 are respectively arranged in front and behind the inner wall of the connecting groove 4. The ends of the two driven arms 12 that are close to each other are rotatably connected to the left and right sides of the inner wall of the connecting groove 4 through a rotating shaft. The sides of the two driven arms 12 that are far apart from each other are respectively attached to two moving rods 401. The ends of the two driven arms 12 that are close to each other are respectively fixedly connected to follower arms 13.

[0028] The above scheme is adopted: by setting the driven arm 12, the two moving rods 401 can press the surface of the two driven arms 12 respectively when they move downward, so that the two driven arms 12 rotate relative to each other, and thus the two driven arms 12 drive the two follower arms 13 to rotate in turn.

[0029] refer to Figure 4 The bottom of the two follower arms 13 near the bottom of the receiver arms 12 is fixedly connected to the top of the two receiver arms 12 at their respective ends. The top of the two follower arms 13 is provided with a slot 14, and the top of the two follower arms 13 at their respective ends is provided with a fixing arm 15.

[0030] The above solution is adopted: by setting follower arms 13, the two follower arms 13 are offset from the moving rod 401 by slots 14 during rotation, and push the two fixed arms 15, thereby driving the two fixed arms 15 to move away.

[0031] refer to Figure 4 The two fixed arms 15 are slidably connected to the outer surface of the moving rod 401 in the middle. The sides of the two fixed arms 15 that are close to each other are respectively in contact with the two follower arms 13. The sides of the two fixed arms 15 that are far apart from each other are respectively fixedly connected to the fixed springs 16. The two fixed springs 16 are both sleeved on the outer surface of the moving rod 401. The ends of the two fixed springs 16 that are far apart from each other are respectively fixedly connected to the inner wall of the connecting groove 4. The tops of the two fixed arms 15 are respectively fixedly connected to the fixed blocks 17.

[0032] The above solution is adopted: by setting the fixing arms 15, the two fixing arms 15 can be pushed by the follower arm 13 respectively, slide away on the moving rod 401, and compress the two fixing springs 16 respectively. The two fixing arms 15 slide and then drive the two fixing blocks 17 to move away respectively.

[0033] refer to Figure 3 and Figure 4 Two fixing blocks 17 are fixedly connected to the top of the two fixing arms 15 on the side that are close to each other, and the ends of the two fixing blocks 17 that are close to each other are respectively inserted into the inner wall of the positioning groove 601.

[0034] The above solution is adopted: by setting the fixing block 17, the fixing block 17 can be separated from the positioning groove 601 when it moves away, so as to release the fixing of the positioning block 6 and thereby release the fixed connection between the bracket 3 and the support base 2.

[0035] The working principle of this utility model:

[0036] In use, the patient moves their chin onto the support 3, and then the detector 103 slides back and forth via the moving base 102 to perform the detection. After completion, the button 9 can be pressed down, causing the displacement block 8 to slide down in the moving groove 7 and the displacement arm 10 to move in the connecting groove 4. At the same time, the two displacement rods 11 move, and the two displacement rods 11 move down while pressing the two driven arms 12, causing the two driven arms 12 to rotate relative to each other. This causes the two follower arms 13 to follow suit and rotate. During the rotation of the two follower arms 13, they are offset from the moving rod 401 by the slots 14, and the two fixing arms 15 slide away from the moving rod 401. The sliding of the two fixing arms 15 compresses the two fixing springs 16, and the two fixing arms 15 move away from the moving rod 401. Move the two retaining blocks 17 to disengage them from the positioning slots 601, thereby releasing the fixation of the positioning blocks 6 and thus releasing the fixed connection between the bracket 3 and the support base 2. Then, the bracket 3 can be removed and cleaned to maintain hygiene. After that, move the bracket 3 back onto the support base 2 and press it down, causing the positioning blocks 6 to be inserted downward into the connecting slot 4. As it moves downward, it presses the surfaces of the two retaining blocks 17, causing them to slide away from the moving rod 401 and compress the two retaining springs 16. When the positioning blocks 6 are fully inserted into the connecting slot 4, the two retaining springs 16 push the two retaining arms 15 to slide, causing the two retaining blocks 17 to move and be inserted into the positioning slots 601 to fix the positioning blocks 6, thereby fixing the bracket 3 onto the support base 2.

[0037] It should be noted that the movable base 102 and the detector 103 are existing devices or equipment in the prior art, or devices or equipment that can be implemented in the prior art. The specific composition and principle of the power supply of the movable base 102 and the detector 103 are clear to those skilled in the art, so they will not be described in detail here.

[0038] In summary, this dry eye testing instrument for ophthalmic examination, through the coordinated operation of the base 1, support 2, bracket 3, connecting groove 4, and assembly structure 5, solves the problem that if the bracket, which comes into direct contact with the patient's skin, is not cleaned during dry eye testing, dust, dirt, sebum, and other impurities may accumulate on the bracket, affecting the hygiene of the testing instrument.
