Anti-shake optometry unit for ophthalmology outpatient service and visual screening

Abstract

The invention relates to the technical field of ophthalmological diagnosis equipment, in particular to an anti-shake optometry unit for ophthalmological outpatient service and visual screening. According to the technical scheme, the optometry unit comprises an optometry unit body and a connecting assembly, wherein the connecting assembly is used for connecting and fixing the optometry unit body; the connecting assembly comprises a plurality of universal connecting pieces connected in series; a first ball head is arranged at one end of each universal connecting piece, a notch is formed in the other end of each connecting piece, and the notches are used for containing the first ball heads of the corresponding next universal connecting pieces. A through hole is formed in the end part of the lower end of each first ball head and communicates with the corresponding notch. An annular rubber part is fixed to the inner wall of each notch, and the inner side wall of the rubber part is fixedly connected with the outer side wall of the first ball head of the next universal connecting piece. The gap between the notch and the first ball head of the next universal connecting piece is filled withthe rubber part through air pressure agitation, and then the two adjacent universal connecting pieces are fixed. According to the anti-shake optometry unit, the labor intensity of medical personnel can be reduced and the optometry accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of ophthalmology diagnostic equipment, in particular to an anti-shake optometry instrument for ophthalmology outpatient clinics and visual screening. Background technique [0002] Refractive errors such as nearsightedness, farsightedness, and astigmatism are the most common visual problems in ophthalmology clinics. Among them, myopia has the greatest impact on people, and its reasons include genetic factors and environmental factors. In recent years, the incidence of myopia in China has remained high, showing a trend of younger age, and has become an increasingly serious public health problem. Refraction examination is a basic and important inspection operation in ophthalmology outpatient service and vision screening, and accurate refraction results will provide the basis for clinical diagnosis and treatment. In practical applications, fixed desktop refractometers and hand-held refractometers are widely us...
