Problems solved by technology

Currently commonly used ophthalmoscopes use visible light. When irradiating newborns, large doses and multiple exposures will cause irreversible damage to the eyes of newborns.
[0005] In addition, because the newborn's eyeballs will move continuously and irregularly, and will actively avoid the light, so when shooting, the ophthalmoscope needs to have a fast focusing system. If the focusing time is long, the captured image may be because of Eye movement that is not clear

Abstract

The invention relates to a fundus digital imaging system. The fundus digital imaging system comprises an illumination device and is characterized in that the illumination device comprises a light source, a converter, a controller and an illumination lens, the converter is respectively connected with the light source, the illumination lens and the controller, the converter is provided with a plurality of filters, the light source is connected to any filter of the converter through the controller, and light passing through the current filter is transmitted to the illumination lens through an optical fiber. According to the fundus digital imaging system, light of different wave lengths is transmitted into the system through the converter, and injury to the eyes can be lowered when the eyes are detected and photographed.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a fundus digital imaging system for newborns. Background technique [0002] Neonatal retinopathy is the main cause of blindness in children in developed countries. With the economic development of our country, this disease has a tendency to rise significantly. In our country, about 20,000 to 30,000 children are blind due to this disease every year. Therefore, the use of special neonatal handheld ophthalmoscope is of great significance for the early screening of neonatal retinopathy. [0003] Wide-angle high-definition fundus digital imaging system mainly includes wide-angle ophthalmoscope, electric focusing mechanism, digital CCD imaging system, halogen ring visible lighting device and other devices. [0004] Since the newborn’s eyes are very fragile and the lens is immature, it is necessary to strictly control the number of inspections and the time of each light exposure when p...
