专门针对高压氧舱内生命体征多参数监测及健康监护的技术实现问题,提出了一种基于IEEE802.15.4协议的无线传感检测技术系统解决方案,阐述了无线传感检测系统的体系结构以及主控制节点与生命体征参数采集传感器节点的硬件设计方法,给出了软件系统架构、软件设计流程及监护软件工作界面,对MAC层帧结构、物理层帧结构及系统时间同步策略进行了详细分析和设计。该系统样机已进入临床实验阶段,文中还给出了患者的临床检测数据,并与实用的进口监护设备的检测数据进行了对比,验证了临床应用的可行性。
In order to carry out monitoring and nursing the multiple physiological parameters of the patients within the hyperbaric oxygen chamber, a system solution based on the wireless sensing technology adapting the IEEE802.15.4 communication protocol was proposed. The architecture of the wearable monitoring and nursing equipment and the hardware of both primary coordinator node and secondary sensor nodes gathering the physiological parameters were designed. The software system structure, procedure, and user interface were presented. The time synchronization strategy was studied in-depth by analyzing the MAC frame and physical layer frame. This paper also compared the testing results of multiple physiological parameters obtained by the experimental prototype in the clinical monitoring and nursing process with that measured by applied equipment COLINBP288 (made in Japan), and testified that the wearable monitoring and nursing equipment can be applicable to the clinical monitoring and nursing process.
