Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multifunctional ophthalmic examination auxiliary device. Background Technology

[0002] Ophthalmic examination aids are essential tools in ophthalmic diagnosis and treatment, designed to assist doctors in performing various eye examinations efficiently and accurately. By providing a stable support structure, they ensure the patient's head and eyes remain in a fixed position during the examination, preventing movement from affecting the results. Utilizing specialized optics, illumination, and imaging components, they help doctors clearly observe the eye structure, corneal condition, and fundus, accurately measuring data such as visual acuity, intraocular pressure, and refractive error. This allows for rapid screening and diagnosis of eye diseases, providing a reliable basis for subsequent treatment planning. They are key devices for improving the accuracy and efficiency of ophthalmic examinations.

[0003] A multifunctional ophthalmic examination aid device is primarily based on various optical, mechanical, and electronic principles. Its mechanical structure stably supports the patient's head, ensuring the eyes are in a fixed and suitable examination position. Utilizing optical imaging principles, such as lens refraction and mirror reflection, it clearly projects images of different parts of the eye onto an imaging element, enabling observation of the cornea, lens, and fundus. Electronic sensing technology measures data such as intraocular pressure and refractive error. For example, intraocular pressure measurement uses a pressure sensor to detect changes in pressure on the surface of the eyeball, while refractive error measurement analyzes the focusing of light after refraction within the eye. Finally, it integrates all the test data to assist doctors in comprehensively and accurately assessing the health of the eyes.

[0004] However, some existing multifunctional ophthalmic examination auxiliary devices suffer from inconvenient height adjustment during use. Medical staff must manually adjust them one by one, a cumbersome and time-consuming process that significantly reduces the continuity of the examination. Furthermore, this adjustment method struggles to achieve precise height control, failing to flexibly adapt to patients of different heights and body types, as well as diverse examination postures. In addition, some devices lack stability during height adjustment, easily becoming loose or stuck. This not only increases the difficulty of operation for medical staff but also causes discomfort to patients due to device wobbling during adjustment. Height deviations affect the precise alignment of the examination instrument with the patient's eye, ultimately interfering with the accuracy of the examination data and hindering the efficient conduct of ophthalmic examinations. Therefore, a multifunctional ophthalmic examination auxiliary device is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multifunctional ophthalmic examination auxiliary device, which aims to improve the problem of inconvenient height adjustment during use of existing multifunctional ophthalmic examination auxiliary devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional ophthalmic examination auxiliary device, comprising a base plate, an L-shaped plate fixedly connected to the front side of the base plate, a connecting plate fixedly connected to the top of the L-shaped plate, a support column fixedly connected to the top of the connecting plate, two telescopic columns fixedly connected to the top of the connecting plate, a moving strip fixedly connected to the top of the two telescopic columns, telescopic rods fixedly connected to the inner walls of the two moving strips on both sides, a moving shaft fixedly connected to the far side of the two telescopic rods, control panels fixedly connected to both sides of the two moving shafts, limit posts fixedly connected to the interior of the far side of the multiple control panels, a retraction column fixedly connected to the bottom of both sides of the moving strip, a retraction shell fixedly connected to the bottom of both sides of the moving strip, multiple limit blocks fixedly connected to the front and rear sides of the two support columns, and a fixing component fixedly connected to the top of the moving strip.

[0007] As a further description of the above technical solution: the fixing component includes two shrinkable columns II, the bottom ends of the two shrinkable columns II are fixedly connected to the top end of the moving strip, the top end of the two shrinkable columns II are fixedly connected to a fixing strip, the top end of the fixing strip is fixedly connected to a contact pad, the top two sides of the top end of the fixing strip are respectively fixedly connected to support strips, two shrinkable columns III are respectively fixedly connected to adjacent sides of the two support strips, the inner walls of adjacent sides of the two support strips are respectively slidably connected to contact strips, and the bottom ends of the fixing strip are respectively fixedly connected to shrinkable shells II.

[0008] As a further description of the above technical solution: springs are sleeved on the outside of both of the two shrinkage columns 2, and the far sides of the two contact strips are respectively fixedly connected to the near sides of the plurality of shrinkage columns 3.

[0009] As a further description of the above technical solution: the bottom ends of the two shrinkable shells are fixedly connected to the top end of the moving strip, and the outer sides of the two springs are slidably connected to the inner walls of the two shrinkable shells respectively.

[0010] As a further description of the above technical solution: the bottom ends of the two shrinking columns are respectively fixedly connected to the inner walls of the bottom ends of the two supporting columns, and springs are sleeved on the outside of the two shrinking columns. The outside of the two springs are respectively slidably connected to the inner walls of the two shrinking shells.

[0011] As a further description of the above technical solution: the two sides of the two moving strips are slidably connected to the inner walls of the two adjacent sides of the two support columns, and the two sides of the two moving shafts are respectively fixedly connected to the inner walls of the two support columns.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the control panel rotates to drive the limiting column to move, the limiting column moves the moving shaft, the moving shaft moves the telescopic rod to extend and retract, and the moving shaft moves the moving strip to slide inside the support column. During the sliding of the moving strip, the retracting column extends and retracts accordingly, and the spring undergoes elastic deformation to provide buffering and restoring force. The limiting block on the support column limits the limiting column, ensuring the stability of the movement of the moving shaft and the moving strip, thereby achieving the effect of adjusting the height of the device, making it convenient for people of different heights to conduct ophthalmic examinations, and improving the applicability and user experience of the device.

[0016] 2. In this utility model, the extension and retraction of the second shrink column drives the fixing strip to rise and fall. The movement of the fixing strip causes the contact pad to come closer to the face, and at the same time, it drives the support strip to move. The movement of the support strip causes the third shrink column to extend and retract, which in turn causes the contact strip to slide on the inner wall of the support strip and fit against both sides of the face. The second spring is sleeved on the outside of the second shrink column. When it extends and retracts, it elastically deforms to provide buffering and restoring force. The second shrink shell guides and protects the second spring, thereby achieving the effect of stabilizing and fixing the facial angle of different people, reducing facial shaking during the examination, providing reliable fixed support for ophthalmic examinations, and improving the accuracy of the examination and the convenience of operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1 to 3 This utility model provides an embodiment of a multifunctional ophthalmic examination auxiliary device, comprising a base plate 1, an L-shaped plate 2 fixedly connected to the front side of the base plate 1, and a connecting plate 3 fixedly connected to the top of the L-shaped plate 2 for easy connection with components such as support columns 4 and telescopic columns 5. The top of the connecting plate 3 is fixedly connected to the support column 4, and the inner wall of the support column 4 has multiple slots that cooperate with limiting columns 10 to fix the moving shaft 8. Two telescopic columns 5 are fixedly connected to the top of the connecting plate 3. When adjusting the height of the device, the telescopic columns 5 assist the moving strip 6 to move smoothly up and down, providing cushioning and shock absorption. The tops of the two telescopic columns 5 are fixedly connected to the moving strip 6, which can slide up and down along the inner wall of the support column 4 under the action of the telescopic columns 5 and the moving shaft 8.

[0025] Telescopic rods 7 are fixedly connected to the inner walls of both sides of the two moving bars 6. When adjusting the height of the device, the telescopic rods 7 can extend and retract with the movement of the moving shaft 8, thereby changing the distance between the moving bar 6 and the moving shaft 8. The moving shaft 8 is fixedly connected to the opposite side of the two telescopic rods 7. The moving shaft 8 can be moved up and down on the inner wall of the support column 4 by the control panel 9. The control panels 9 are fixedly connected to both sides of the two moving shafts 8, providing operators with a convenient and precise adjustment method, enabling the device to quickly adapt to the needs of people of different heights, and improving the ease of operation and adjustment accuracy of the device. Limiting posts 10 are fixedly connected to the inner walls of the opposite sides of the multiple control panels 9. When the moving shaft 8 moves to the appropriate height, the control panel 9 is rotated to make the limiting post 10 engage in the corresponding slot. The bottom ends of both sides of the moving bar 6 are fixedly connected to the retractable post 12. One end of the retractable post 12 is fixed to the bottom end of the moving bar 6, and the other end is connected to the inner wall of the bottom end of the support column 4.

[0026] During the up-and-down movement of the moving bar 6, the retractable column 12 can extend and retract with the movement of the moving bar 6. The elastic force generated by the compression spring during the extension and retraction can play a role in buffering and resetting. The bottom ends of both sides of the moving bar 6 are respectively fixedly connected to the retractable shell 13. During the movement of the moving bar 6, the retractable shell 13 and the retractable column 12 work together to form a stable support structure. Multiple limiting blocks 11 are fixedly connected to the front and rear sides of the two support columns 4, which improves the accuracy and stability of the slot cooperation between the limiting column 10 and the support column 4. The top of the moving bar 6 is fixedly connected to a fixing component for fixing.

[0027] Reference Figures 2 to 4 The fixing component includes two retractable columns 15, the bottom ends of which are fixedly connected to the top of the movable strip 6. The top of the two retractable columns 15 is fixedly connected to a fixing strip 17, which can move up and down under the action of the retractable columns 15. At the same time, it serves as a base platform for supporting components such as the contact pad 18 and the support strip 19. The top of the fixing strip 17 is fixedly connected to the contact pad 18, which improves the patient's comfort during the examination and enhances the fixing effect, preventing the accuracy of the examination results from being affected by the patient's facial slippage.

[0028] Support bars 19 are fixedly connected to both sides of the top of the fixing bar 17. The support bars 19 can stably support the contact bar 21, keeping it stable during movement and preventing it from shifting. Two contraction columns 20 are fixedly connected to the adjacent sides of the two support bars 19. When the contact bar 21 is squeezed by external force, the contraction columns 20 can contract accordingly to absorb the impact force. After the external force disappears, they can automatically return to their original position under the action of the spring. The contact bar 21 is slidably connected to the inner wall of the adjacent side of the two support bars 19. Driven by the contraction columns 20, it can slide horizontally along the inner wall of the support bar 19, thereby conforming to both sides of the patient's face. Contraction shells 16 are fixedly connected to both sides of the bottom end of the fixing bar 17. This ensures that the contraction columns 15 will not tilt during movement, and has the beneficial effect of extending the service life of the contraction columns 15.

[0029] Reference Figures 1 to 3 Each of the two contraction columns 15 is fitted with a spring 22. When the contraction columns 15 extend or retract, the springs 22 compress or stretch accordingly, generating an elastic restoring force. The distant sides of the two contact strips 21 are fixedly connected to the adjacent sides of the multiple contraction columns 20. When the patient's facial contours are different, the contraction columns 20 can be extended or retracted to adjust the horizontal position of the contact strips 21, allowing the contact strips 21 to fit closely to both sides of the patient's face. The bottom ends of the two contraction shells 16 are fixedly connected to the top of the moving strip 6, ensuring the normal operation of the contraction columns 15 and the springs 22. The outer sides of the two springs 22 are slidably connected to the inner walls of the two contraction shells 16.

[0030] When spring 22 extends and retracts with the contraction column 15, it maintains linear motion under the constraint of the inner wall of the contraction shell 16, preventing twisting or deviation. The bottom ends of the two contraction columns 12 are fixedly connected to the inner walls of the bottom ends of the two support columns 4, providing a stable support base for the contraction columns 12. During the up-and-down movement of the moving bar 6, the contraction columns 12 can extend and retract accordingly. Springs 14 are sleeved on the outside of each of the two contraction columns 12. When the moving bar 6 rises, the springs 14 are compressed, storing elastic potential energy; when the moving bar 6 descends, the springs 14 release elastic potential energy, assisting the moving bar 6 to fall smoothly. The outside of the two springs 14 are slidably connected to the inner walls of the two contraction shells 13.

[0031] The shrink shell 13 also protects the spring 14 from external wear or corrosion, ensuring its normal operation. The two moving bars 6 are slidably connected to the inner walls of the adjacent sides of the two support columns 4 on both sides, and the two moving shafts 8 are fixedly connected to the inner walls of the two support columns 4 on both sides. This provides a reliable power transmission path for height adjustment, ensuring that the moving bars 6 can be precisely adjusted to the operator's desired height. The outer sides of the multiple limiting columns 10 are fixedly connected to the inner walls of the adjacent sides of the multiple limiting blocks 11 on both sides, ensuring that the moving bars 6 can be stably fixed after being adjusted to the appropriate height, improving the reliability of the device's height adjustment and providing stable support for ophthalmic examinations.

[0032] Two movable shafts 8 are slidably connected to the inner walls of both sides of the movable strip 6, achieving effective linkage between the movable shafts 8 and the movable strip 6. This ensures smooth height adjustment and facilitates daily maintenance and repair of the device. The bottom ends of two retractable shells 13 are fixedly connected to the inner walls of the bottom ends of two support columns 4, providing a stable mounting base for the internal springs 14 and retractable columns 12. The retractable shells 13 not only protect the internal components from external environmental influences but also guide the movement of the springs 14 and retractable columns 12. The top of the base plate 1 is fixedly connected to the instrument compartment 23, protecting the ophthalmic examination instruments and equipment from damage, ensuring normal operation of the instruments during the examination, and improving the accuracy and reliability of the examination results. The top of the instrument compartment 23 is fixedly connected to the detection compartment 24, providing a professional and convenient operating space for ophthalmic examinations, optimizing the examination process, and improving the efficiency and quality of ophthalmic examinations.

[0033] Working principle: When height adjustment is required, the control panel 9 rotates, causing the movable shaft 8 to move within the groove on the inner wall of the support column 4. The movement of the movable shaft 8 causes the telescopic rod 7 to extend or retract, which in turn pushes the movable strip 6 to slide within the groove inside the support column 4. Simultaneously, the retractable column 12 extends or retracts within the inner wall at the bottom of the support column 4. The spring 14 provides buffering and restoring force. The limiting column 10 and the limiting block 11 cooperate to ensure that the movable shaft 8 moves along a fixed trajectory. When the movable shaft 8 is engaged in grooves of different heights on the support column 4, the position of the movable strip 6 is fixed, thus achieving precise adjustment and stable fixation of the device height. This facilitates the inspection needs of different groups of people, improving the convenience and accuracy of inspections.

[0034] When the patient brings their face close, the movement of the movable strip 6 causes the contraction column 15 to extend or retract, thereby moving the fixing strip 17 along with the contact pad 18 up and down to adjust to a height suitable for the patient's face. The spring 22 compresses or extends within the contraction shell 16, providing stable cushioning and restoring force for the fixing strip 17. When the patient's face contacts the contact pad 18, the pressure causes the contact strip 21 to slide against the inner wall of the support strip 19, causing the contraction column 20 to compress and deform. The elastic restoring force of the contraction column 20, combined with the guiding effect of the support strip 19, causes the contact strip 21 to adaptively conform to different facial contours. At the same time, the spring 22 maintains the overall stability of the fixing strip 17, thereby achieving precise and flexible fixation of the facial angles of different people, effectively avoiding head shaking during the examination, improving the stability and comfort of the examination, and ensuring the accuracy of the examination results.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
