摘要

通常,术后病人护理需要医务委员会在医院进行长时间的观察。在此观察期间,医疗委员会手动将患者的实时重要信息插入医疗信息系统。如果患者配备可穿戴设备,通过机器学习系统进行实时数据采集和数据处理,可以改进这种人工操作,使其更加可靠。在这项工作中,我们提出了一种基于商用智能手环的高效低成本的术后患者护理监测系统。由于目前的智能带仅限于单输入单输出(SISO)通信,即在短距离范围内只有一个智能带可以连接到一个智能手机,我们提出了一种基于信号集中器的新架构,将商业智能带的能力扩展到多输入多输出(MIMO)通信。根据我们的实验结果,我们提出的单一集中器架构允许248:N通信,即在同一房间内同时使用248个智能带,并且收集的数据传输给任意数量的N个医生,而不受距离限制。通过考虑具有多个集中器的系统,我们还提出了一种用于智能带的M:N架构通信。

Efficient and low cost MIMO communication architecture for smartbands applied to postoperative patient care
Frequently, postoperative patient care requires a long period of observation in hospitals by the medical board. During this observation period, the medical board manually inserts time to time vital information of the patients into the medical information system. Such manual procedure can be improved and become more reliable if the patients are equipped with wearable devices that allow the real-time data acquisition and the data processing by machine learning systems. In this work, we propose an efficient and low cost monitoring system for postoperative patient care based on commercial smartbands. Since the current smartbands are restricted to single input single output (SISO) communication, i.e. only one smartband can connect to one smartphone in a short distance range, we propose to expand the commercial smartband capability to a multiple input multiple output (MIMO) communication by proposing a new architecture based on a signal concentrator. According to our experimental results, our proposed architecture with a single concentrator allows a 248: N communication, i.e. the simultaneous usage of 248 smartbands in a same room and the data collected data is transmitted to any number N of physicians without distance restrictions. By considering a system with multiple concentrators, we also propose an M:N architecture communication for smartbands.
