Complex compound eye lens type neonatal jaundice phototherapy illuminating system

Abstract

The invention relates to a complex compound eye lens type neonatal jaundice phototherapy illuminating system. The complex compound eye lens type neonatal jaundice phototherapy illuminating system comprises an LED light source, a collimating lens Z, a compound eye lens F1, a compound eye lens F2 and a focusing lens F3 which are arranged on the same optical axis from left to right, wherein monochromatic light emitted by the LED light source is changed into parallel light beams after passing through the collimating lens Z; the parallel light beams pass through a complex compound eye lens which is composed of the compound eye lens F1 and the compound eye lens F2, and then are irradiated to the focusing lens F3; and after being focused by the focusing lens F3, the light forms a focused illuminating plane at the right side of the optical axis. According to the complex compound eye lens type neonatal jaundice phototherapy illuminating system, a blue-light LED and a green-light LED are adopted as a phototherapy light source to replace a conventional light source, so that the light energy utilization rate is greatly increased, the phototherapy effect with high uniformity is realized, the therapeutic effect is better, the biological safety is higher and side effects are fewer; and meanwhile, the illuminating system adopts a miniature design, so that the whole set of equipment is compact in structure and is convenient to carry.

Description

technical field [0001] The invention belongs to the technical field of optical medical instruments, and relates to a uniform lighting system with a specific wavelength LED as a light source, which achieves constant uniformity, constant irradiance, and constant spot area through three methods. Specifically, it is a composite lighting system. Fly-eye lens phototherapy lighting system for neonatal jaundice. Background technique [0002] Jaundice is a common disease in newborns. According to statistics, about 70% of babies in the world will have different degrees of jaundice symptoms within one week after birth, and their skin will appear yellowish brown. For neonatal jaundice, the current mainstream treatment methods include blood transfusion, drug therapy, acupuncture, swimming therapy, touch therapy, gene therapy and light therapy. Exchange transfusion therapy is mainly used to treat hemolytic jaundice, but it is easy to cause vascular blockage, venous thrombosis and other h...
