摘要

(1) 目的:本研究旨在为早产儿非接触式重症监护奠定基础。(2)方法:使用单色照相机和时分复用控制照明在三种不同波长(660 nm、810 nm 和 940 nm)下对仔猪模型进行动脉血氧饱和度和心率测量。(3) 结果:利用该照相系统和我们新设计的算法进行进一步分析,对心跳检测和血氧饱和度计算进行了评估。在一动不动的个体中,只需稍加干预,就能在轻微呼吸时清晰地分离心跳和呼吸。在这种情况下,非接触式和接触式饱和度测量的平均差异为 0.7%(RMSE = 3.8%,MAE = 2.93%)。(4) 结论:在理想的动物实验条件下,新型传感器被证明是有效的。这些结果为进一步开发非接触式生命体征监测系统提供了系统性改进。本文介绍的结果是朝着开发用于新生儿重症监护室的非接触式传感器系统培养箱迈出的重要一步。

Investigation of a Camera-Based Contactless Pulse Oximeter with Time-Division Multiplex Illumination Applied on Piglets for Neonatological Applications
(1) Objective: This study aims to lay a foundation for noncontact intensive care monitoring of premature babies. (2) Methods: Arterial oxygen saturation and heart rate were measured using a monochrome camera and time-division multiplex controlled lighting at three different wavelengths (660 nm, 810 nm and 940 nm) on a piglet model. (3) Results: Using this camera system and our newly designed algorithm for further analysis, the detection of a heartbeat and the calculation of oxygen saturation were evaluated. In motionless individuals, heartbeat and respiration were separated clearly during light breathing and with only minor intervention. In this case, the mean difference between noncontact and contact saturation measurements was 0.7% (RMSE = 3.8%, MAE = 2.93%). (4) Conclusions: The new sensor was proven effective under ideal animal experimental conditions. The results allow a systematic improvement for the further development of contactless vital sign monitoring systems. The results presented here are a major step towards the development of an incubator with noncontact sensor systems for use in the neonatal intensive care unit.
