Problems solved by technology

[0005] The purpose of the present invention is to overcome the existing percutaneous instrument for measuring neonatal jaundice, which can only detect jaundice index but cannot effectively predict neonatal jaundice and give an alarm, and use a xenon flash lamp as a light source to cause the product to be bulky and inconvenient to carry. On the basis of the effective jaundice alarm algorithm obtained through clinical trials, a portable percutaneous neonatal jaundice alarm device is provided

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] The hardware of the present invention includes two parts: optics and a microcontroller system, the optics part realizes the detection of light signals, and the microcontroller is responsible for the execution of instructions, the processing of data and the display of results.

[0026] The optical part includes an LED light source (01), a coaxial fiber optic probe (02), a filter (03) and a photoelectric conversion component (04). Wherein the switch of the LED light source (01) is controlled by the I / O port of the microprocessor (06) of the microcontroller system. The light emitted by the LED light source (01) irradiates the neonatal skin from one side of the coaxial optical fiber probe (02), and the reflected light is irradiated to the filter (03) on the other side through the coaxial optical fiber probe (02). The blue light and green light compo...

Abstract

The present invention relates to a percutaneous detection neonatal jaundice warning apparatus. It uses LED (light-emitting diode) flash lamp as detection light source, and includes the functions of measurement, recording, analysis-diagnosis and warning, etc. Said apparatus not only can detect and record neonatal jaundice index, but also can utilize warning algorithm to give out warning signal for newborn capable of occurring pathological jaundice.

Description

technical field [0001] The invention relates to a percutaneous neonatal jaundice alarm instrument, which uses an LED (light-emitting diode) flashlight as a detection light source, and relates to an instrument for measuring, recording, analyzing, diagnosing and alarming. The instrument is suitable for dynamic non-invasive detection and early warning of neonatal jaundice. Background technique [0002] The accumulation of bilirubin in the blood, tissue and interstitial fluid causes yellow staining in the skin, mucous membrane, sclera and some body fluids, which is clinically called jaundice. Neonatal jaundice (also known as neonatal hyperbilirubinemia) is a common disease in the neonatal period. Neonatal jaundice can be divided into physiological and pathological. Physiologically speaking, physiological jaundice means that the total serum bilirubin content of newborns does not exceed a permissible range (the serum bilirubin level of newborns in my country is about 10-14mg / dl)...
