Description

Ophthalmic device with anti-infection structure Technical Field The utility model belongs to the technical field of ophthalmic examination, and particularly relates to ophthalmic equipment with an anti-infection structure. Background The main purpose of ophthalmic examination is to evaluate eye health status, discover and diagnose eye diseases in time, through examination, doctors can know vision condition, eye structure, intraocular pressure and the like of patients, including eye appendages and eye anterior segment examination. Eye attachment examinations include examinations of the eyelid, conjunctiva, lacrimal apparatus, eyeball position and orbit, and various instruments used for ophthalmic examinations mainly include slit-lamp microscopes, tonometers, direct ophthalmoscopes and the like. At present, when a patient performs eye examination, because the base for supporting the chin of the patient on the instrument is in contact with the skin of the patient, in order to prevent the patient from being infected with each other, medical staff needs to disinfect the base for supporting the chin of the patient on the instrument after the patient examination is completed, but a plurality of people for daily examination in a hospital increase the working intensity of the medical staff.
