穿戴式动态黄疸水平及生理参数监测系统设计
Design of wearable dynamic jaundice level and physiological parameter monitoring system
摘要
Abstract
Due to the high risk of neonatal jaundice and the limitations of traditional monitoring methods,a wearable dynamic jaundice level and physiological parameter monitoring system has been designed to meet the clinical demand for non-invasive dynamic jaundice de-tection equipment.The system includes a forehead-mounted wireless physiological signal collector,a Bluetooth communication host and a data analysis platform based on Lab VIEW.The system uses the highly integrated MAX86916 optical sensor to synchronously collect four-channel photoplethysmography(PPG)signals,and obtains bilirubin,heart rate,and blood oxygen saturation data through signal processing.The nRF52832 microcontroller with Bluetooth Low Energy(BLE)protocol is used for wireless communication.The data is transmitted wirelessly to the Bluetooth communication host,and then uploaded to the LabVIEW program of the PC via USB for display and storage.To verify the functionality and performance of the system,basic parameter tests,and comparative tests of each physiologi-cal parameter with commercial instruments were conducted in sequence.The device(13.5 g,41 mm×29.7 mm×15.1 mm)can con-tinuously monitor for 5 hours.The detection range of the bilirubin prediction model is 1～13 mg/dL.Measurements demonstrated bili-rubin,heart rate and blood oxygen are in strong agreement with standard instruments(p＞0.05).And the maximum absolute errors for bilirubin,HR,and SpO2 measurements are 0.96 mg/dL,1 bpm,and 2.1％,respectively.Moreover,the system can sensitively track the decrease in heart rate after exercise and the variations in blood oxygen during breath-holding.The experiment results show that the system is effective in monitoring jaundice,heart rate and blood oxygen level.It features lightweight design,wearability,multi-para-metric detection,and non-invasive dynamic measurement capabilities.After further optimization,it is expected to be applied in neonatal clinical monitoring.关键词
