Problems solved by technology

[0003] In the prior art, when performing ophthalmic examinations, most of the inspectors directly open the eyelids with their hands, causing the bacteria on the hands to easily enter the eyes and affect the follow-up inspection. Some inspectors use eyelid clips, but the eyelid clips need to be held by the doctor It is very inconvenient to use and operate, and it is prone to cross-infection

Embodiment 1

[0027] see Figure 1 to Figure 7 , the present invention provides a technical solution: an ophthalmological examination system, a bracket 32 ​​is arranged on the surface of the workbench 1, a fixing part is arranged on the bracket 32, a fixed plate 2 is fixedly connected to the upper surface of the workbench 1, and the fixed plate The side of 2 is fixedly connected with two supporting plates 3, and auxiliary parts for stretching the eyelids are all arranged on the two supporting plates 3; auxiliary parts include slider 4 and moving plate 12, and the surface of supporting plate 3 is provided with for sliding 4 stretches into the chute 5, the surface of the slide block 4 is connected with a gear 11 for fixed axis rotation, the surface of the support plate 3 is slidably connected with rack row one 6 and rack row two 7, rack row one 6 and rack row Both 7 are meshed with the gear 11, the connecting plate 13 is jointly hinged between the rack row 1 6 and the moving plate 12, the sid...

Embodiment 2

[0033] Embodiment two, the difference with the preceding embodiment is:

[0034] In order to avoid the user's lower jaw against the bracket 32 ​​for a long time, causing discomfort, further, the bracket 32 ​​includes an arc-shaped portion 33, and a protective pad is arranged in the arc-shaped portion 33. By setting the arc-shaped portion 33, the jaw and the bracket The contact area of ​​the seat 32 is increased, and the pad is provided to reduce pain and improve the comfort of the device during use.

Embodiment 3

[0035] Embodiment three, the difference from the previous embodiment is:

[0036] In order to increase the frictional force between the fixed ring 29 and the user's head and improve the fixing quality, further, the inner side of the fixed ring 29 is provided with a rubber anti-slip pad to improve the frictional force and prevent the head from shaking during inspection.

[0037] Working principle: when the eye examination system is in use, such as figure 1 and Figure 6 As shown, the user first pulls the fixing ring 29 upwards, drives the telescopic part of the telescopic rod 2 30 to extend and stretches the spring 2 31 at the same time, puts the mandible in the arc portion 33 on the bracket 32, and then loosens the fixing ring 29 , at this time, under the action of the elastic restoring force of spring 2 31, the fixed ring 29 is driven to be stuck on the user's head, and it is fixed, and by setting the anti-skid pad, the frictional force is increased, and the fixing quality i...

Abstract

The invention discloses an ophthalmic examination system, and relates to the technical field of ophthalmic examination. The ophthalmic examination system comprises a workbench, the upper surface of the workbench is fixedly connected with a fixed plate, the side surface of the fixed plate is fixedly connected with two support plates, the surface of a slide block is rotatably connected with a gear through a fixed shaft, the side surface of a movable plate is fixedly connected with a pressing component, a second rack row is connected with a sleeve block through an elastic component, the side surface of the movable plate is slidably connected with a baffle, the baffle abuts against a first rack row, and a second connecting plate is jointly hinged between the baffle and the second rack row. According to the ophthalmic examination system, the effects that a hydraulic cylinder drives a push plate and two push rods to move continuously, then two elastic pieces in two auxiliary components are driven to firstly abut against the eyes of a user, then the two movable plates are driven to move upwards or downwards, so that the two elastic pieces move upwards or downwards to open the eyelids of the user, the eyelids do not need to be opened with hands in the whole process, and bacteria on the hands are prevented from entering the eyes to cause infection, and the inspection safety is ensured are achieved.

Description

technical field [0001] The invention relates to the technical field of ophthalmic examination, in particular to an ophthalmic examination system. Background technique [0002] Ophthalmological examination is a general examination of the eye, including examination of the ocular adnexa and anterior segment. Ocular adnexa examination includes examination of eyelids, conjunctiva, lacrimal apparatus, eyeball position and orbit. Ophthalmological examination can evaluate eye function. Commonly used visual function examinations include visual psychophysical examination and visual electrophysiological examination. Visual acuity, visual field and other examinations require The examiner uses appropriate equipment to conduct the examination and the patient makes a judgment through psychological activities, so it is called a visual psychophysical examination. [0003] In the prior art, when performing ophthalmic examinations, most of the inspectors directly open the eyelids with their h...
