Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to an auxiliary vision testing device for ophthalmology. Background Art

[0002] The full name of ophthalmology is "eye disease specialist", which is a discipline that studies diseases occurring in the visual system, including the eyeball and its associated tissues.

[0003] Vision test refers to the ability of the eyes to distinguish fine objects. The most commonly used eye test chart is the Snellen Chart, invented by Danish ophthalmologist Hermann Snellen in 1862. The person undergoing the eye test must keep a distance of 20 feet from the eye test chart. There are 11 lines of English words on the eye test chart, all in capital letters. The top line has the largest font, and the fonts of the following lines will become smaller and smaller. The English letters must be read from top to bottom, and there is a score next to each line of words, which is the eye test result.

[0004] In the prior art, during vision testing, in order to facilitate the tester to rest, the test is usually performed in a sitting position. For example, a Chinese invention patent with a publication number of CN108433694B discloses a conveniently adjustable auxiliary vision testing device for ophthalmology, which allows patients to sit for testing, can provide rest assistance for weak patients, can assist weak patients in performing vision tests normally, and is conducive to improving the accuracy of vision test results for weak patients.

[0005] However, in the actual vision test process, although the existing technology can improve the accuracy of the test results to a certain extent, it still has certain limitations. Since the two eyes are usually tested separately during the test, in order to improve the accuracy of the test of each eye, when testing one eye, the other eye needs to be covered. The existing technology lacks an automatic covering device. When testing the eyes of weak patients, the existing weak patients manually hold the covering device to cover their eyes for a long time. Due to the weak physical condition of the patients, it is difficult for them to accurately hold the covering device to cover their eyes for a long time. For normal testers, holding the covering device for a long time will also cause hand soreness or even shaking, affecting the tester's concentration, which can easily affect the accuracy of the test results. Summary of the invention

[0006] In view of the problem in the prior art that the eyes of weak persons to be tested cannot be automatically covered and that the only solution is to provide seats for the weak persons to be tested, the purpose of the present invention is to provide an auxiliary vision testing device for ophthalmology.

[0015] Optionally, a collecting box is detachably mounted on the vertical plate, and a combing rod cooperating with the bristles is evenly and fixedly mounted on the vertical plate.

[0016] Optionally, a sponge pad that cooperates with the seating board is fixedly mounted on the top wall of the mounting block.

[0017] Optionally, a backrest is fixedly mounted on the top wall of the mounting block, and a pull ring is fixedly mounted on the top wall of the cover plate.

[0018] Optionally, a slide rail that slidably cooperates with the mounting block is fixedly mounted on the base.

[0019] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0020] In the above scheme, by setting up a cover plate, the person to be tested can rotate the cover plate to a suitable position and cover a single eye. At the same time, the first elastic telescopic rod can fix the horizontal position of the cover plate, and the second elastic telescopic rod can fix the cover plate in the vertical direction. Therefore, the person to be tested does not need to hold the cover plate for a long time for testing, which causes the person to be tested to lose physical strength and affects the accuracy of the test results, thereby improving the test accuracy.

[0021] By setting up a disinfection component, when the person to be tested finishes the test and stands up, the fourth spring drives the piston plate to move upward and squeezes the gas in the cavity, so that the gas in the cavity flows into the disinfection cavity through the first air pipe, and drives the disinfectant to flow into the disinfection tank through the disinfection pipe, and then the cover plate is disinfected through the disinfection holes on the disinfection tank. Since the cover plate is in direct contact with the eyes of the person to be tested, the cover plate is disinfected, thereby effectively preventing the person to be tested from getting an eye infection and affecting the accuracy of the eye test of the person to be tested, thereby further improving the test accuracy.

[0022] By setting a sealing plate, as the horizontal plate moves upward, it gradually contacts the sealing plate and applies thrust to the sealing plate. Then, under the action of the thrust, the sealing plate drives the connecting hole to move upward. When the person to be tested loses contact with the sitting plate, the sealing plate drives the connecting hole to contact with the first air pipe. At this time, the gas above the horizontal plate in the cavity flows into the disinfection chamber through the connecting hole and the first air pipe. Then, after the person to be tested loses contact with the seat, the cover plate can be disinfected, thereby preventing the disinfectant from contacting the eyes of the person to be tested and causing discomfort to the person to be tested, thereby improving the comfort of the person to be tested.

[0023] By setting up a cleaning component, when the person to be tested sits on the seat, the person to be tested drives the horizontal plate to move downward through the riding plate and the connecting rod, and squeezes the gas under the horizontal plate in the cavity, so that the gas flows into the elastic telescopic tube through the second air pipe, and then the elastic telescopic tube stretches and drives the cleaning rod to move upward along the groove. In the process of the cleaning rod moving upward, the cleaning bristles are driven to move upward. In the process of the cleaning bristles moving, the dust on the mirror can be cleaned, thereby effectively preventing the dust from affecting the accuracy of the test, and further improving the accuracy of the test.

[0049] like Figures 1 to 9 As shown, an embodiment of the present invention provides an auxiliary vision testing device for ophthalmology, comprising a seat 1 and a base 2, a vertical plate 3 is vertically fixedly installed on the base 2, a mirror 4 is fixedly installed on the vertical plate 3, the seat 1 comprises a mounting block 101, a side plate 102 is symmetrically fixedly installed on the top wall of the mounting block 101, and a covering component 5 is provided on the side plate 102;

[0050] The covering assembly 5 includes a vertical groove provided on the side plate 102, a mounting rod 501 is movably installed in the vertical groove, a covering plate 502 is fixedly installed on one end of the mounting rod 501 away from the vertical groove, a turntable 507 is rotatably installed on the bottom wall of the mounting rod 501, a first spring 503 is fixedly installed between the turntable 507 and the vertical groove, a ratchet 504 slidably matched with the mounting rod 501 is rotatably installed on the side plate 102, a sliding groove is provided on the ratchet 504, a connecting rod 505 slidably matched with the sliding groove is fixedly installed on the mounting rod 501, a spring 506 is installed between the ratchet 504 and the side plate 102, and a control assembly 6 matched with the mounting rod 501 is provided on the side plate 102.

[0051] The control assembly 6 includes a first horizontal groove provided on the side plate 102, a first elastic telescopic rod 601 cooperating with the ratchet 504 is slidably installed in the first horizontal groove, a second spring 602 is fixedly installed between the first elastic telescopic rod 601 and the first horizontal groove, a limiting groove 603 is evenly provided on the installation rod 501, a second horizontal groove is provided on the side plate 102, a second elastic telescopic rod 604 cooperating with the limiting groove 603 is slidably installed in the second horizontal groove, and the second elastic telescopic rod 604 is close to the limiting groove 60 3 is an inclined surface, a return spring 605 is installed between the second elastic telescopic rod 604 and the second horizontal groove, a push rod 606 is vertically slidably installed on the side plate 102, the bottom wall of the push rod 606 is an inclined surface, a push block 607 is fixedly installed on the side wall of the push rod 606, and the push block 607 is provided with an inclined groove cooperating with the second elastic telescopic rod 604, a third spring 608 is fixedly installed between the top wall of the push block 607 and the side plate 102, and a disinfection component 7 cooperating with the cover plate 502 is provided on the side plate 102.

[0052] In the initial state, the first spring 503 and the third spring 608 are in a free extension state. At this time, the push rod 606 drives the first elastic telescopic rod 601 to move and stretch the second spring 602 through the inclined surface, and at this time, the push rod 606 drives the second elastic telescopic rod 604 to move and stretch the reset spring 605 through the push block 607. When in use, the person to be tested first sits on the seat 1 and looks at the mirror 4. Since the existing test requires a test distance of five meters, in order to save space, a distance of 2.5m is maintained between the seat 1 and the mirror 4. The test distance of 5 meters is obtained through the mirror image. Then the person to be tested can first rotate the installation rod 501 and make The cover plate 502 is parallel to the eyes of the person to be tested. When the person to be tested rotates the installation rod 501, the installation rod 501 drives the ratchet 504 to rotate through the connecting rod 505. At this time, the clockwork 506 accumulates force, and then during the rotation of the ratchet 504, the inclined surface of the ratchet 504 teeth applies a thrust to the first elastic telescopic rod 601, and the first elastic telescopic rod 601 contracts. When the teeth of the ratchet 504 are out of contact with the first elastic telescopic rod 601, the first elastic telescopic rod 601 stretches and inserts into the teeth of the ratchet 504 again. Then, under the action of the first elastic telescopic rod 601, the ratchet 504 cannot be driven by the connecting rod 505. The mounting rod 501 is flipped over so that the cover plate 502 can be fixed in the horizontal direction. Then, when the cover plate 502 is rotated to a suitable position, the person to be tested can pull the cover plate 502 upward to cover the eyes of the person to be tested. During the upward movement of the cover plate 502, the mounting rod 501 drives the limit groove 603 and the turntable 507 to move upward. At this time, the first spring 503 is stretched and has a tendency to recover. As the limit groove 603 moves upward, the limit groove 603 contacts the inclined surface of the second elastic telescopic rod 604 and applies a thrust to the inclined surface of the second elastic telescopic rod 604. Then, the thrust Under the action of the second elastic telescopic rod 604, the output end of the second elastic telescopic rod 604 contracts and has a tendency to recover. When the second elastic telescopic rod 604 contacts the limiting groove 603 again, the second elastic telescopic rod 604 stretches and inserts into the limiting groove 603. Then, under the action of the second elastic telescopic rod 604, the mounting rod 501 can be fixed in the vertical direction, that is, the covering plate 502 can be fixed with the cooperation of the first elastic telescopic rod 601 and the second elastic telescopic rod 604, thereby eliminating the need for the person to be tested to hold the covering plate 502 for a long time for testing, which causes the person to be tested to be physically exhausted and affects the accuracy of the test results, thereby improving the test accuracy.

[0053] When the other eye needs to be tested, the person to be tested first pulls the push rod 606 on the side of the used cover plate 502, and then drives the push block 607 to move upward during the upward movement of the push rod 606, and disengages from the second elastic telescopic rod 604. At this time, the third spring 608 is compressed and has a tendency to recover. When the push block 607 disengages from the second spring 602, the reset spring 605 contracts and drives the second elastic telescopic rod 604 to disengage from the limiting groove 603. At this time, the first spring 503 contracts and drives the cover plate 502 to reset downward through the turntable 507 and the mounting rod 501. At the same time, the push rod 606 gradually disengages from the first elastic telescopic rod 601 during the upward movement. At this time, the second spring 602 contracts and drives the first elastic telescopic rod 604 to disengage from the limiting groove 603. The retracted rod 601 is out of contact with the ratchet 504, at which time the clockwork 506 stretches and drives the cover plate 502 to rotate and reset through the ratchet 504, the connecting rod 505, and the mounting rod 501. When the cover plate 502 is reset, the person to be tested can release the push rod 606, and then the third spring 608 stretches and drives the push rod 606 to reset through the push block 607. When the push rod 606 is reset, the person to be tested can pull the cover plate 502 on the other side and test the other eye. When the test is completed, the person to be tested can pull the push rod 606 on the other side again to reset the cover plate 502 on the other side. That is, after the test is completed, the person to be tested only needs to pull the push rod 606 to automatically reset the cover plate 502, thereby improving the convenience of the test.

[0054] like Figure 2 , Figure 7 , Figure 8 As shown, the disinfection component 7 includes a disinfection chamber 701 provided on the side panel 102, a feeding port communicating with the outside is provided on the top wall of the disinfection chamber 701, a plug plate 702 is detachably installed in the feeding port, a disinfection plate 703 is fixedly installed on the top wall of the side panel 102, a disinfection groove 704 is provided on the disinfection plate 703, disinfection holes 705 cooperating with the cover plate 502 are evenly provided on the side wall of the disinfection groove 704, a disinfection pipe 706 communicating with the disinfection chamber 701 is inserted on the bottom wall of the disinfection groove 704, and an air supply component 8 cooperating with the disinfection chamber 701 is provided on the mounting block 101.

[0055] The air supply component 8 includes a cavity 801 opened on the mounting block 101, a horizontal plate 802 is slidably mounted in the cavity 801, a fourth spring 803 is fixedly mounted between the bottom wall of the horizontal plate 802 and the cavity 801, a connecting rod 804 is fixedly mounted on the top wall of the horizontal plate 802, a riding plate 805 is fixedly mounted on the top wall of the connecting rod 804, an exhaust valve 806 is inserted in the cavity 801, a first air pipe 807 connected to the disinfection chamber 701 is fixedly mounted on the output end of the exhaust valve 806, and one end of the first air pipe 807 away from the cavity 801 is displaced above the liquid level of the disinfectant, an air inlet valve 808 connected to the outside of the input end is also inserted in the cavity 801, and a cleaning component 9 cooperating with the cavity 801 is provided on the vertical plate 3.

[0056] A mounting groove is provided on the top wall of the cavity 801, and a sealing plate 809 cooperating with the first air pipe 807 is slidably installed in the mounting groove. A connecting hole 810 connected to the first air pipe 807 is provided on the sealing plate 809, and a fifth spring 811 is installed between the top wall of the sealing plate 809 and the mounting groove.

[0057] By adopting the above technical solution, in the initial state, the fourth spring 803 is in a free extension state. When the person to be tested sits on the seat 1, the person to be tested will drive the riding plate 805 to move downward. During the downward movement of the riding plate 805, the horizontal plate 802 is driven downward by the connecting rod 804. At this time, the fourth spring 803 is compressed and has a tendency to recover. During the downward movement of the horizontal plate 802, the space above the horizontal plate 802 in the cavity 801 is inhaled through the intake valve 808. Then, when the test is over, the person to be tested first resets the cover plate 502. After the cover plate 502 is reset, the person to be tested can stand up from the seat 1 and break away from the seat 1. At this time, the fourth spring 803 The horizontal plate 802 stretches and drives the horizontal plate 802 to move upward. During the upward movement of the horizontal plate 802, the gas in the cavity 801 located above the horizontal plate 802 is squeezed, and the gas flows into the disinfection chamber 701 through the first air pipe 807. Then the pressure in the disinfection chamber 701 increases. Under the action of the pressure, the disinfectant in the disinfection chamber 701 flows into the disinfection tank 704 through the disinfection tube 706, and the cover plate 502 is disinfected through the disinfection hole 705 on the disinfection tank 704. Since the cover plate 502 is in direct contact with the eyes of the person to be tested, the cover plate 502 is disinfected, thereby effectively preventing the person to be tested from getting an eye infection and affecting the accuracy of the eye test of the person to be tested, thereby further improving the test accuracy.

[0058] In the initial state, the fifth spring 811 is in a free extension state. At this time, the sealing plate 809 blocks the first air pipe 807. Then, when the fourth spring 803 drives the horizontal plate 802 to move upward, the gas above the horizontal plate 802 in the cavity 801 tends to flow to the outside. Then, as the horizontal plate 802 moves upward, it gradually contacts the sealing plate 809 and applies a thrust to the sealing plate 809. Then, under the action of the thrust, the sealing plate 809 drives the connecting hole 810 to move upward. When the person to be tested is out of contact with the sitting plate 805, the sealing plate 809 drives the connecting hole 810 to contact with the first air pipe 807. At this time, the gas above the horizontal plate 802 in the cavity 801 flows into the disinfection chamber 701 through the connecting hole 810 and the first air pipe 807. Then, after the person to be tested is out of contact with the seat 1, the cover plate 502 can be disinfected, thereby preventing the disinfectant from contacting the eyes of the person to be tested and causing discomfort to the person to be tested, thereby improving the comfort of the person to be tested.

[0059] like Figure 1 , Figure 3 , Figure 8 , Fig. 9 As shown, the cleaning component 9 includes a groove 901 symmetrically opened on the vertical plate 3, a cleaning rod 902 is slidably installed in the groove 901, cleaning bristles 903 are evenly fixedly installed on the side walls of the cleaning rod 902, an elastic telescopic tube 904 is fixedly installed between the bottom wall of the cleaning rod 902 and the groove 901, and a second air pipe 905 connected to the elastic telescopic tube 904 is inserted into the cavity 801.

[0060] The vertical plate 3 is provided with a collecting box 906 detachably mounted thereon, and the vertical plate 3 is provided with a combing rod 907 matched with the bristles evenly and fixedly mounted thereon.

[0061] By adopting the above technical solution, during the process of the person to be tested going back and forth for the test, the shoes of the person to be tested may be covered with dust and will adhere to the surface of the mirror 4. Then, after a long period of testing, a large amount of dust will accumulate on the surface of the mirror 4, which will easily affect the accuracy of the test. When the person to be tested sits on the seat 1, the person to be tested drives the horizontal plate 802 to move downward through the riding plate 805 and the connecting rod 804, and squeezes the gas below the horizontal plate 802 in the cavity 801, so that the gas flows into the elastic telescopic tube 904 through the second air pipe 905, and then the elastic telescopic tube 904 stretches and drives the cleaning rod 902 to move upward along the groove 901, and drives the cleaning hair 903 to move upward in the process of the cleaning rod 902 moving upward. In the process of the cleaning hair 903 moving, the dust on the mirror 4 can be cleaned, thereby effectively preventing the dust from affecting the accuracy of the test, and further improving the accuracy of the test.

[0062] When the test is over and the person under test stands up, the fourth spring 803 stretches and drives the horizontal plate 802 to move upward. During the upward movement of the horizontal plate 802, air is sucked from the elastic telescopic tube 904 through the second air pipe 905 into the space below the horizontal plate 802 in the cavity 801. Then the elastic telescopic tube 904 contracts and drives the cleaning bristles 903 to return to their original position through the cleaning rod 902, thereby preparing for work again.

[0063] As the cleaning rod 902 drives the cleaning bristles 903 to move up and down, the cleaning bristles 903 gradually come into contact with the combing rod 907 and hit the combing rod 907. Then, under the action of inertia, the dust on the cleaning bristles 903 is separated from the cleaning bristles 903, thereby effectively preventing the dust from adhering to the mirror 4 again. At the same time, the combing rod 907 can also comb the cleaning bristles 903, thereby improving the cleaning effect of the mirror 4. After the dust is separated from the cleaning bristles 903, the dust will fall into the collection box 906 under the action of gravity, thereby facilitating dust cleaning.

[0064] like Figure 8 As shown, a sponge pad 10 that matches the sitting board 805 is fixedly mounted on the top wall of the mounting block 101 .

[0065] By adopting the above technical solution, when the person to be tested sits on the seating board 805, the sponge pad 10 will be deformed and fit tightly with the person to be tested, thereby increasing the force-bearing area of ​​the person to be tested. Since the person to be tested is physically weak, the pressure on the person to be tested can be reduced by increasing the force-bearing area of ​​the person to be tested, thereby improving the comfort of the person to be tested, allowing the person to be tested to perform the test with peace of mind, thereby further improving the accuracy of the test.

[0066] like Figure 1 , Figure 2 As shown, a backrest 103 is fixedly mounted on the top wall of the mounting block 101 , and a pull ring 11 is fixedly mounted on the top wall of the cover plate 502 .

[0067] By adopting the above technical solution, after sitting on the chair 1, the person to be tested can lean against the backrest 103, thereby improving the comfort of the person to be tested and making the person to be tested relax, which is beneficial to improving the accuracy of the test; and when it is necessary to move the position of the cover plate 502, the person to be tested can move the position of the cover plate 502 through the pull ring 11, thereby facilitating the person to be tested to move the cover plate 502; and after the test, while the cover plate 502 is disinfected, the pull ring 11 can also be disinfected at the same time to further prevent cross infection.

[0068] like Figure 1 As shown, a slide rail 12 which slidably cooperates with the mounting block 101 is fixedly mounted on the base 2 .

[0069] By adopting the above technical solution, when it is necessary to move the distance between the person to be tested and the mirror 4, the medical staff can push the base 2 on the slide rail 12 to move the seat 1, and then adjust the distance between the person to be tested and the mirror 4. At the same time, the design of the slide rail 12 can also prevent pedestrians from walking between the mirror 4 and the seat 1 during the test, causing the person to be tested to be unable to concentrate on the test, thereby affecting the test accuracy, thereby improving the test accuracy.

[0070] The working process of the present invention is as follows:

[0071] When the present invention is used, first, the person to be tested sits on the seat 1, and then moves the cover plate 502 to a suitable position to cover a single eye. At the same time, the first elastic telescopic rod 601 and the second elastic telescopic rod 604 can indirectly fix the position of the cover plate 502, thereby eliminating the need for the person to be tested to hold the cover plate 502 for a long time for testing.

[0072] Then, when the person to be tested sits on the sitting board 805, the connecting rod 804 drives the horizontal board 802 to move downward, and squeezes the gas in the space below the cavity 801. Then, the gas flows to the elastic telescopic tube 904 through the second air pipe 905 and causes the elastic telescopic tube 904 to stretch. The stretched elastic telescopic tube 904 drives the cleaning hair 903 to clean the mirror 4 through the cleaning rod 902, thereby effectively preventing dust from affecting the accuracy of the test.

[0073] After the test is finished, the person to be tested can pull the push rod 606 upwards, and then the first elastic telescopic rod 601 and the second elastic telescopic rod 604 move away from the mounting rod 501, and release the fixing of the cover plate 502, and then the first spring 503 and the spring 506 drive the cover plate 502 to reset;

[0074] Finally, after the person to be tested stands up, the horizontal plate 802 moves upward, so that the gas above the cavity 801 flows into the disinfection cavity 701 through the first air pipe 807, and then the disinfectant, under the action of the gas, passes through the disinfection tube 706, the disinfection groove 704, and the disinfection hole 705 to disinfect the cover plate 502, thereby effectively preventing the person to be tested from eye infection and affecting the accuracy of the eye test of the person to be tested.

[0075] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0076] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
