Description

Technical Field

[0001] The present invention relates to the technical field of human eye vision inspection, and in particular to a fully automatic human eye vision inspection device and method. Background Art

[0002] The human eye vision examination device includes an optometer, which is mainly used to measure the refractive state of the eyeball, such as myopia, hyperopia or astigmatism, as well as parameters such as corneal curvature, to check the convergence of light after entering the eyeball. It uses the emmetropia state as the standard to measure the degree of convergence difference between the examined eye and the emmetropia eye. The optometer can be used for diagnostic optometry for fitting soft corneal contact lenses. It does not require mydriasis and can quickly measure the degree of refraction. The optometer's optometry results are all automatically printed without conversion. Generally, a patient can be measured in a few seconds to a few minutes, and the degree of refractive error can be quickly measured, providing more accurate refractive power and interpupillary distance for lens correction. The following problems exist in the prior art:

[0003] Because when the existing human eye vision examination device ophthalmometer performs human eye examination, the human eye needs to be aligned with the hole that emits the examination light and the head needs to be kept stable for a certain period of time in order to perform normal optometry. However, with the rise of electronic products, the patients who need eye examinations are getting younger and younger. When performing optometry on younger children, it is difficult to perform optometry quickly and stably because children are naturally active and cannot maintain good stability, and their eyes are small, which affects the optometry efficiency. At the same time, the adjustment of the support plate and the guard plate for the chin and the nose tip also needs to be manually adjusted, which affects the adjustment speed. It is inconvenient to repeatedly adjust and observe the ophthalmometer to complete the adjustment. Summary of the invention

[0064] The working principle of the fully automatic human eye vision inspection device is described in detail below.

[0065] like Figure 1-8 As shown, when performing a fully automatic human eye vision test, the patient's chin is placed on the arc plate 543 on the top of the control box 52, and the rubber pad 544 is used to improve the placement comfort. At the same time, the buffer spring 542 on the top of the fixed bottom plate 541 is used to provide buffering, and the damper 545 is used to prevent the buffer spring 542 from rebounding repeatedly, and the rubber sleeve 546 is used to provide protection for the buffer spring 542. Then, the lifting motor 511 at the bottom of the extension plate 51 can be started to drive the threaded rod 512 to rotate, and the threaded connection between the threaded rod 512 and the control box 52 can drive the entire control box 52. The limiting slide bar 522 is connected with the slide groove 514 to rise steadily until the limiting plate 513 at the top of the threaded rod 512 stops against the bottom of the inner wall of the control cabin 521, so that the patient's eyes and the eyeball viewing hole 21 are kept on the same horizontal line. At this time, the forehead arc limiting rod 524 between the two lifting racks 523 can be pressed against the patient's forehead. When the height is high, it only needs to start the rotating motor 526 to drive the gear 527 to rotate, and the meshing of the gear 527 and the lifting rack 523 in the gear groove 525 can drive the two lifting racks 523 to descend synchronously until they reach the appropriate height. The U-shaped bracket 532 is then raised or lowered to a suitable position for the back of the patient's head by starting the electric push rod 531, and the other end of the elastic band 533 is passed through the direction-changing hole 535 and pulled back until the elastic band 533 is tightly attached to the back of the patient's head. The Velcro fur surface 536 and the Velcro hook surface 534 are then used to bond the patient's head as a whole to prevent the child's head from moving around. After the patient's head is fixed, the direction control lever 4 can be controlled to start the adjustment motor 112 in the motor slot 111, thereby driving the front and rear threaded rods 113. Rotate, cooperate with the threaded connection between the front and rear threaded rods 113 and the front and rear displacement plates 114 to drive the overall drive box 121 to move backward, and observe the display 3 until the eyeball viewing hole 21 is close to the patient's eyeball. When an eyeball examination is completed, the adjustment motor 122 can be started again to drive the left and right threaded rods 124 to rotate in the left and right slide grooves 123, and cooperate with the threaded connection between the left and right slide grooves 123 and the left and right displacement plates 125 to drive the overall left and right displacement plates 125 and the tray 126 to drive the ophthalmometer body 2 to move left and right, which is convenient for changing the eyeball examination and adjusting the left and right position of the eyeball viewing hole 21.

[0066] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
