A visual fundus examination instrument

Abstract

The invention discloses a visible fundus examination tester which comprises a fundus examination lens and a tester body. An infrared receiving digital camera and a first circuit control wiring port are arranged on the head portion of the tester body, the fundus examination lens comprises an aspheric surface eye objective lens, a lighting optics focusing set and a micro imaging objective lens set. A second circuit control wiring port is arranged behind the micro imaging objective lens set, and the fundus examination lens is connected with the digital camera through the butting joint of the first circuit control wiring port and the second circuit control wiring port. The infrared rays sent by a flashlight and an infrared light emitter are reflected to the aspheric surface eye objective lens through a reflection mirror, and are projected into the fundus of an eyeball through the aspheric surface eye objective lens. The infrared rays reflected by the fundus are imaged to the digital camera through the imaging of the aspheric surface eye objective lens and the micro imaging objective lens set. Through the mentioned mode, the visible fundus examination tester can catch sight of a fundus imaging picture intuitively, and shoot accurately, and carry out storage or printing.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a visual fundus inspection instrument. Background technique [0002] At present, when the traditional fundus examination instrument is in operation, the examinee performs fundus imaging through the fundus examination mirror and optical lighting lamp. The operator's eyes need to be aligned with a pair of microscopes to see the fundus imaging. When imaging, the eyes are always facing the microscope lens. When the operation time is long, it is easy to cause visual fatigue, and the diagnosis result may not be accurate enough. In addition, the diagnosis result is recorded manually, and the inspection instrument itself has no automatic recording or storage function. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a visual fundus inspection instrument, which can intuitively see the imaging pictures of the fundus...
