Abstract

The invention discloses a forward type annular lighting system with a digital lens, which comprises a sleeve, wherein an annular light guide plate is arranged at the head end of the sleeve; an illuminating device is arranged at the tail end of the sleeve; a built-in optical fiber is arranged on the inner wall of the sleeve; one end of the built-in optical fiber is optically connected with the endpart of the annular light guide plate; the other end of the built-in optical fiber is optically connected with the illuminating device; the illuminating device comprises a cold light source and an external optical fiber, wherein the external optical fiber conducts light generated by the cold light source to the built-in optical fiber; and the external optical fiber is optically connected with thebuilt-in optical fiber. The invention provides the forward type annular lighting system with the digital lens.

Description

【Technical field】 [0001] The invention relates to an optical lighting system, which is a new type of medical inspection equipment, and is mainly used for photographing the optical system of the fundus of premature infants and infants. 【Background technique】 [0002] Retinopathy of prematurity is the leading cause of blindness in children in developed countries. With the development of our country's economy and social progress, this common disease in developed countries has shown an obvious upward trend in our country. For this reason, the Ministry of Health of my country issued the "Guidelines for the Treatment of Oxygen and Retinopathy in Premature Infants" in 2004. , emphasizing that premature infants and low-birth-weight infants born in the hospital, especially those with a history of oxygen inhalation, must undergo fundus examinations to detect retinopathy of prematurity early and treat them early to reduce blindness and disability in premature infants. [0003] Accordin...
