Abstract

The invention provides a bilirubin measuring device, comprising an optical device and a lens. The optical device comprises an incoming passage for emitting test light out and a receiving passage for receiving reflected light. The lens comprises a barrel body having both ends opened, and a polarizer and polarization analyzer arranged at one end of the barrel body; the polarizer covers and attachesto an end face of the incoming passage; the polarization analyzer covers and attaches to an end face of the receiving passage. The bilirubin measuring device using a polarized liquid technology and providing the polarizer and the polarization analyzer acquires polarized light via the polarizer, and non-polarized light is filtered by the polarization analyzer; therefore, only the polarized light isdetected, reflected light from skin surface is eliminated, a difference between blue light and green light for calculating bilirubin in blood is increased, and calculating results are more accurate and precise.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a bilirubin measuring device. Background technique [0002] Bilirubin accumulates in blood tissues and interstitial fluid, causing yellow staining of skin, mucous membranes, sclera and some body fluids, which is clinically called jaundice. Neonatal hyperbilirubinemia is a common disease in the neonatal period, which can lead to kernicterus and bilirubin encephalopathy in severe cases. Therefore, clinically, dynamic observation of neonatal jaundice is required for timely detection and treatment. [0003] The existing bilirubin measuring device utilizes the linear relationship between transcutaneous bilirubin and total serum bilirubin, and estimates the concentration of total serum bilirubin by measuring the concentration of transcutaneous bilirubin. During the measurement, the blue light (460nm) and green light (550nm) light sources alternately emit light, incident on the skin, a...
