[0002] Ophthalmic examination is a general examination of the eye, including examination of the ocular adnexa and anterior segment of the eye; examination of the ocular adnexa includes examination of the eyelid, conjunctiva, lacrimal apparatus, eye position and orbit; ophthalmic examination can assess the function of the eye. Common visual function tests include visual psychophysics tests (such as visual acuity, visual field, color vision, dark adaptation, stereopsis, contrast sensitivity) and visual electrophysiology tests. Visual acuity, visual field and other tests require the examiner to use appropriate equipment to examine and make judgments by the patient through psychological activity, hence the name visual psychophysics test.

[0003] At present, the existing multifunctional intelligent ophthalmic examination device still has the following disadvantages in actual use:

[0004] (1) The height of the chin rest and forehead rest in the existing multifunctional intelligent ophthalmic examination device is inconvenient to adjust, which wastes time and affects the examination efficiency of the doctor;

[0005] (2) After use, the existing multifunctional intelligent ophthalmic examination device generally needs to be wiped and disinfected with disinfectant, which is very inconvenient. Due to the inconvenience, disinfection work cannot be performed in time, and disinfection is often performed after multiple people use it or use it for a day, which not only makes the patient experience poor, but also easily leads to cross infection;

[0006] (3) Due to the large number of ophthalmic diseases, inexperienced doctors cannot find the corresponding disease introduction from memory when examining patients, and need to search in the network database, which is time-consuming and delays the treatment of patients.

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0047] Please see Figures 1 to 6 A multifunctional intelligent ophthalmic examination device, comprising:

[0048] The base 1 and the main body 2 of the inspection equipment are located on the upper end of the base 1. A chin support 4 and a forehead support 5 are connected to the base 1 on the front side of the main body 2 via a bracket 3.

[0049] The front of the main body 2 of the examination device is provided with an optical lens 21, and the rear of the main body 2 of the examination device is provided with a display screen 22 and a control panel 23. The doctor can control the main body 2 of the examination device through the control panel 23, so that the optical lens 21 is aimed at the patient's eyes, and then control the main body 2 of the examination device to perform the examination. The processor inside the main body 2 of the examination device processes the optical information collected by the optical lens 21 and displays it on the display screen 22 for the doctor to view. The doctor can also transmit the information on the display screen 22 to the Internet through the control panel 23. The Internet analyzes the data and searches the network database, and transmits the patient's condition and medical records to the display screen 22 through the control panel 3. The doctor can make an accurate diagnosis of the patient based on the condition displayed on the display screen 22 and his / her own medical knowledge.

[0050] The bracket 3 includes a quadrangular prism 31 fixed to both sides of the upper end of the base 1. The chin support 4 and forehead support 5 are slidably mounted on the quadrangular prism 31. The chin support 4 and forehead support 5 are respectively provided with a first sliding hole 41 and a second sliding hole 51 on both sides of the quadrangular prism 31 for the quadrangular prism 31 to pass through. Teeth 311 are evenly provided on the opposite sidewalls of the quadrangular prism 31. The left and right sides of the chin support 4 are respectively provided with a first sliding groove 42 communicating with the opposite side of the first sliding hole 41. Symmetrical first tooth blocks 43 are slidably mounted in the two first sliding grooves 42. The first tooth blocks 43 are respectively engaged with the teeth 311. The chin support 4 is also provided with a first driving component 44 that causes the two first tooth blocks 43 to slide towards or away from each other. The first driving component can disengage the first tooth blocks 43 on both sides from the teeth 311, so that the chin support 4 can slide on the quadrangular prism 311. The chin support 4 slides on the column 31 to facilitate height adjustment. After adjustment, the first drive assembly 44 re-engages the first tooth block 43 with the tooth 311 to fix the height of the chin support 4. A first compression spring 45 is fixed between the chin support 4 and the base 1. The first compression spring 45 is sleeved on the quadrangular prism 31. The forehead support 5 is provided with a positioning assembly 6, which can fix the height position of the forehead support 5 on the quadrangular prism 31 to prevent the forehead support 5 from sliding up and down when the patient uses it. Before the test, the patient first rests their chin on the arc-shaped groove 410 in the middle of the chin support 4. The first compression spring 45 has a certain supporting force. The patient adjusts the height of the chin support 4 according to their own height, and then fixes the position of the chin support 4 through the first drive assembly 44. Then, the height of the forehead support 5 is adjusted and fixed by the positioning assembly 6, so that the height of both can meet the patient's own needs.

[0051] The chin support 4 is provided with fixing posts 7 on both sides. The opposite side walls of the fixing posts 7 are connected to fixing sleeves 72 by elastic telescopic members 71. The upper end of the fixing sleeve 72 is provided with an inner rod 73. The opposite side walls of the upper end of the inner rod 73 are provided with second telescopic disinfection blocks 74. The second telescopic disinfection blocks 74 are in contact with the working surface of the forehead support 5 and can slide along its length. The lower end of the opposite side wall of the fixing sleeve 72 is provided with first telescopic disinfection blocks 75. The first telescopic disinfection blocks 75 are in contact with the working surface of the chin support 4 and can slide along its length. The lower end of the chin support 4 is provided with a second drive assembly 76 for driving the two second telescopic disinfection blocks 74 and the two first telescopic disinfection blocks 75 to slide towards or away from each other. The second drive assembly 76 can drive the fixed sleeves 72 on both sides to slide towards or away from each other, thereby driving the two first telescopic disinfection blocks 75 and the two second telescopic disinfection blocks 74 to slide towards or away from each other respectively. The elastic telescopic member 71 can extend and retract with the movement of the fixed sleeves 72, and at the same time can limit the movement direction of the fixed sleeves 72, that is, the movement towards or away from each other, so that the first telescopic disinfection blocks 75 and the two second telescopic disinfection blocks 74 can move and return to their original positions; during the movement, the first telescopic disinfection blocks 75 and the two second telescopic disinfection blocks 74 can extend and retract according to the curvature of the working surfaces of the chin rest 4 and the forehead rest 5, so that the disinfection wiping surface is always in contact with the working surfaces of the two, achieving effective wiping disinfection; Figure 1 As shown, the fixing post 7, elastic telescopic member 71, fixing sleeve 72, and inner rod 73 are all positioned away from the quadrangular prism 31 and are located on the front side of the quadrangular prism 31. The second drive assembly 76 is also located on the front side of the first drive assembly 44. The inner rod 73 can slide within the fixing sleeve 72, allowing the distance between the forehead support 5 and the chin support 4 to be adjustable, without restricting the forehead support 5 from sliding on the quadrangular prism 31.

[0052] like Figure 2 and Figure 3 As shown, the chin support 4 has a sliding cavity 46 inside that connects the two first sliding grooves 42, and a receiving groove 47 that communicates with the sliding cavity 46 is opened in the middle of the bottom wall of the sliding cavity 46.

[0053] The first drive assembly 44 includes a slide rod 441 slidably disposed in the slide cavity 46, a top block 443 slidably disposed in the receiving groove 47, and a screw 442 threadedly connected to the bottom wall of the receiving groove 47. The top block 443 has inclined surfaces on both sides and has a structure that is narrower at the top and wider at the bottom. The opposite side walls of the two slide rods 441 are inclined surfaces and match the side walls of the top blocks 443 respectively. The upper end of the screw 442 is rotatably connected to the lower end of the top block 443. The lower end of the screw 442 extends out of the chin support 4 and is connected to a handle 444. The outer wall of the slide rod 441 is also fitted with a first return spring 445. The two ends of the first return spring 445 are fixedly connected to the inner walls of the first tooth block 43 and the first slide groove 42 respectively. Turning the handle 444 allows the screw 442 to rotate and move upwards or downwards, thereby moving the top block 443 up or down. When moving upwards, the inclined surfaces on both sides of the top block 443 push the sliding rods 441 on both sides to move away from each other, so that the first tooth block 43 gradually engages with the tooth 311, thus fixing the chin support 4. When moving downwards, under the action of the rebound force of the first return spring 445, the first return spring 445 moves towards each other, so that the first tooth block 43 gradually disengages from the tooth 311, making it easier to adjust the height of the chin support 4.

[0054] Preferably, the upper ends of the opposite sidewalls of the two quadrangular prisms 31 are evenly provided with teeth 312, and the interior of the left and right sides of the forehead support 5 is respectively provided with a second sliding groove 52 that communicates with the side opposite to the second sliding hole 51.

[0055] The positioning component 6 includes a second toothed block 61 slidably disposed in the second slide groove 52 and a pull rod 62 fixedly connected to the side away from the second toothed block 61. The second toothed block 61 meshes with the toothed block 312. The pull rod 62 extends out of the side wall of the forehead support 5 and is fixedly connected to the pull ring 63 on the side away from the second toothed block 61. A second return spring 64 is sleeved on the outer wall of the pull rod 62. The two ends of the second return spring 64 are fixedly connected to the second toothed block 61 and the inner wall of the second slide groove 52, respectively. When using the device, the patient places their chin on the arc-shaped groove 410 in the middle of the chin support 4 and fixes the position of the chin support 4 with the first drive assembly 44. Then, the patient adjusts the height of the forehead support 5, inserts the index fingers of both hands into the pull ring 63 and pulls them outwards. The second tooth block 61 disengages from the second tooth 312. At the same time, the patient holds the sides of the forehead support 5 and moves the forehead support 5 up or down until its height is just at the forehead. Then, the patient releases the pull ring 63 and resets it under the action of the second return spring 64, thereby re-engaging the second tooth block 61 with the second tooth 312 and fixing the height of the forehead support 5.

[0056] Preferably, the lower end of the chin support 4 is fixed with a mounting frame 48, and the interior of the chin support 4 is also provided with a cavity 49 that communicates with the interior of the mounting frame 48;

[0057] The second drive assembly 76 includes a worm gear 761 rotatably disposed within the mounting frame 48, a first rotating shaft 762 and a second rotating shaft 763 rotatably disposed on both sides of the cavity 49, a turbine 764 fixed on the first rotating shaft 762, a first gear 765 and a first drum 766, and a second gear 767 and a second drum 768 fixed on the second rotating shaft 763. Pull ropes 769 are wound in opposite directions on the first drum 766 and the second drum 768, and the other ends of the two pull ropes 769 are fixedly connected to the middle of the outer side wall of the fixed sleeve 72. The fixed column 7 and the chin support 4 are provided with holes for the pull ropes 769 to pass through. The turbine 764 is meshed with the worm gear 761, and the first gear 765 is meshed with the second gear 767. The rotating worm gear 761 can drive the first drum 766 and the second drum 768 to move in opposite directions through the turbine 764 and gear transmission, thereby driving the two pull ropes 769 to roll up or unwind simultaneously. This causes the two first telescopic disinfection blocks 75 and the two second telescopic disinfection blocks 74 to move towards or away from each other, realizing the wiping and disinfection of the chin support 4 and the forehead support 5. This is convenient, quick, time-saving, and labor-saving, allowing doctors to disinfect the chin support 4 and the forehead support 5 in a timely manner.

[0058] Preferably, the elastic telescopic member 71 includes limiting posts 711 fixedly disposed at the upper and lower ends of the opposite sidewalls of the fixed post 7, and a third return spring 712 sleeved on the outer wall of the limiting posts 711. The two ends of the third return spring 712 are fixedly connected to the sidewalls of the fixed post 7 and the fixed sleeve 72, respectively. The limiting posts 711 are not connected to the sidewalls of the fixed sleeve 72. The limiting posts 711 facilitate the increase of the hardness of the third return spring 712, and facilitate the fixed sleeve 72 to move linearly or approximately linearly along the limiting posts 711 and the third return spring 712, that is, to move towards or away from each other.

[0059] Preferably, a second compression spring 721 is fixedly connected to the inner bottom of the fixed sleeve 72, and the upper end of the second compression spring 721 is fixedly connected to the lower end of the inner rod 73 to prevent the inner rod 73 from separating from the fixed sleeve 72.

[0060] Preferably, the second telescopic disinfection block 74 includes an L-shaped sleeve 741 fixedly connected to the upper end of the inner rod 73, a second short column 742 slidably disposed inside the L-shaped sleeve 741 near the forehead support 5, and a second disinfection cotton block 743 fixedly attached to the second short column 742 near the forehead support 5. A third compression spring 744 is fixedly connected to the side of the second short column 742 near the L-shaped sleeve 741. The other end of the third compression spring 744 is fixedly connected to the inner wall of the L-shaped sleeve 741. The L-shaped sleeves 741 on both sides are symmetrically arranged. Since the working surface of the forehead support 5 in contact with the human body is arc-shaped, in order to match the arc-shaped working surface, under the elastic force of the third compression spring 744, the second disinfection cotton block 743 always fits against the arc-shaped working surface to achieve effective disinfection.

[0061] Preferably, the first telescopic disinfection block 75 includes a fixing block 751 fixed to the lower end of the fixing sleeve 72 away from the fixing post 7, and a first disinfection cotton block 753 slidably disposed at the lower end of the fixing block 741 via a first short post 752. The fixing block 751 has cylindrical holes 754 at both ends near the first disinfection cotton block 753. A fourth compression spring 755 is fixedly connected to the top wall of each cylindrical hole 754, and the lower end of the fourth compression spring 755 is fixedly connected to the upper end of the first short post 752. An arc-shaped groove 410 is provided in the middle of the chin rest 4. When the first disinfection cotton block 753 slides to wipe the working surface, under the elastic force of the fourth compression spring 755, the first disinfection cotton block 753 always remains in contact with the working surface of the chin rest 4, achieving effective disinfection.

[0062] Preferably, the first disinfectant cotton block 753 and the second disinfectant cotton block 743 have the same structure, both including a fixed shell 756 and a disinfectant cotton 757 detachably connected to the fixed shell 756. The fixed shell 756 is provided with a liquid cavity 759, and the side wall of the fixed shell 756 near the disinfectant cotton 757 is uniformly provided with liquid outlet holes 758 communicating with the liquid cavity 759.

[0063] Preferably, the upper end of the fixed column 7 is provided with a liquid storage bladder 8. By squeezing the liquid storage bladder 8, the disinfectant can flow from the pipe into the liquid storage bladder 8, thereby adsorbing onto the disinfectant cotton 757, and then wiping for disinfection. The liquid storage bladder 8 is connected to the liquid cavity 759 through pipes. The liquid storage bladder 8 can be provided with a liquid filling port and a sealing cap for easy addition of disinfectant. Alternatively, an internal threaded ring can be integrally provided at the lower end of the liquid storage bladder 8, and an external threaded interface can be provided at the upper end of the fixed column 7. The liquid storage bladder 8 is threadedly connected to the upper end of the fixed column 7. A cavity is provided inside the fixed column 7, and the pipe is connected to the cavity to achieve liquid communication. To prevent the disinfectant in the liquid storage bladder 8 from moving downward due to gravity, a valve one-way valve can be provided inside the liquid storage bladder 8 not near the internal threaded ring. The disinfectant can only be squeezed out when external force is applied by hand, thus avoiding waste of disinfectant.

[0064] The working principle of this invention is as follows: The patient first rests their chin on the arc-shaped groove 410 in the middle of the chin rest 4. The first compression spring 45 provides a certain supporting force. The patient adjusts the height of the chin rest 4 according to their own height and fixes the height of the chin rest 4 by the handle 444. Then, the index fingers of both hands are inserted upward into the pull ring 63 and pulled outward to make the height of the forehead support 5 meet their own needs, and then the pull ring 63 is released. An optical lens 21 is set on the front of the examination device body 2, and a display screen 22 and a control panel 23 are set on the rear. The doctor controls the position of the examination device body 2 through the control panel 23 so that the optical lens 21 is aligned with the patient's eyes. Then, the doctor controls the examination device body 2 to perform the examination by operating the control panel 23. The processor inside the examination device body 2 controls the optical lens. The optical information collected by 21 is processed and displayed on the display screen 22 for the doctor to view. The doctor can also transmit the information on the display screen 22 to the Internet through the control panel 3. The Internet analyzes the data and searches with the network database. The patient's condition and medical record are transmitted to the display screen 22 through the control panel 3. The doctor can make an accurate diagnosis of the patient based on the condition displayed on the display screen 22 and his own medical knowledge. After the patient's examination is completed, the patient or doctor can squeeze the reservoir 8 to wet the disinfectant cotton 757 with disinfectant, and then rotate the worm gear 761 to disinfect the surfaces of the chin support 4 and forehead support 5 that come into contact with the human body. Then, rotate the worm gear 761 in the opposite direction to restore the disinfectant cotton 757 to its original position (i.e., on both sides of the chin support 4 and forehead support 5).

[0065] The present invention has been further described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
