Problems solved by technology

However, the ophthalmic examination chairs in the prior art usually have a single structure, and cannot adjust the height of the seat and the position of the headrest according to different human body heights and proportions, which is inconvenient, and when it is necessary to lie flat or recline When adjusting, the adjustment of the backrest often requires manual adjustment, which is laborious and causes certain adverse effects in the actual use process. Therefore, we propose an ophthalmic examination device with a lifting adjustment function

Abstract

The invention belongs to the field of ophthalmologic examination devices, and particularly relates to an ophthalmologic examination device with a lifting adjustment function. Aiming to solve the problems that an existing ophthalmologic examination seat is generally single in structure, the height of the seat and the position of a headrest cannot be adjusted according to different human body heights and proportions, the existing ophthalmologic examination seat is inconvenient, and labor is wasted due to the fact that backrest adjustment is often required to be manually adjusted when lying flator reclining adjustment is required, the following schemes are put forward currently, specifically, the ophthalmologic examination device with the lifting adjustment function comprises an adjusting backrest and a cushion seat, a connecting rotating rod is rotatably mounted on the inner surface of the lower end of the adjusting backrest, and an electric driving cavity is formed in the cushion seat.The ophthalmologic examination device has the function of automatically adjusting the inclination angle of the backrest, the trouble of manual adjustment is avoided, the functions of height adjustment and headrest position adjustment are achieved, adjustment can be conducted according to the use requirements of different people, and the application range of the ophthalmologic examination device is widened.

Description

technical field [0001] The invention relates to the technical field of ophthalmic examination devices, in particular to an ophthalmic examination device with a lifting adjustment function. Background technique [0002] General examination in ophthalmology, including ocular adnexa and anterior segment examination. Examination of the ocular adnexa includes examination of the eyelids, conjunctiva, lacrimal apparatus, eye position, and orbit. At present, the ophthalmic examination devices used on the market are generally in the form of seats, mainly composed of cushions, chair legs and backrests. When performing ophthalmic examinations for patients, staff often need to open the eyelids with one hand and operate with the other hand. Inspection: usually by inspection and palpation under natural light. Main observations: first, whether there are congenital abnormalities in the eyelids, such as eyelid defects, palpebral fissure narrowing, ptosis, etc.; second, eyelid skin abnormal...
