An anti-shake refractor for ophthalmology clinic and vision screening

Abstract

The present invention relates to the technical field of ophthalmic diagnostic equipment, in particular to an anti-shake optometry instrument for ophthalmic outpatient clinics and visual screening; the technical solution adopted is to include a optometry instrument body and a connecting assembly, and the connecting assembly is used to connect and fix optometry instrument body; the connection assembly includes several universal connectors connected in series, one end of the universal connector is provided with a first ball head, and the other end of the connector is provided with a recess, which is used to accommodate the The first ball head of a universal joint; the lower end of the first ball head is provided with a through hole, and the through hole communicates with the notch; the inner wall of the notch is fixed with a ring-shaped rubber part, and the inner side of the rubber part The wall is fixedly connected to the outer wall of the first ball head of the next universal joint; the rubber part is agitated by air pressure to fill the gap between the recess and the first ball head of the next universal joint, thereby fixing two adjacent universal joints connectors. The invention can reduce the labor intensity of medical personnel and improve the accuracy of optometry.

Description

technical field [0001] The invention relates to the technical field of ophthalmic diagnostic equipment, in particular to an anti-shake refractometer used for ophthalmic clinics and visual screening. Background technique [0002] Refractive errors such as myopia, hyperopia, and astigmatism are the most common visual problems in ophthalmology clinics. Among them, myopia has the greatest impact on people, and the reasons include genetic factors and environmental factors. In recent years, the incidence of myopia in China has remained high, and it has shown a trend of younger age, and has become an increasingly serious public health problem. Refractive examination is a basic and important examination operation in ophthalmology clinics 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 used more frequently. Among them, hand-held...
