基于无线传感器网络的输液监测系统设计
|
摘要
近些年来，随着人口数目的急剧增加和医疗资源的相对匮乏，严重增加了社会的医疗负担。住院患者中，95%以上都会采用输液的方式进行治疗。但是传统的输液方式具有输液速度不够准确、异常情况难以及时处理等弊端。
根据实际需求，本文设计了一个基于无线传感器网络的输液监测系统。系统是由PC机和多个不同功能的节点组成的分布式系统，各个节点之间通过由ZigBee技术构建的无线传感器网络进行数据传输，通过以太网接口完成了协调器节点与PC机之间的通信。系统采用红外光电技术实现对输液滴速的测量，并将各个监测终端节点的输液信息上传到PC机，对各个终端节点进行实时监测。当出现异常情况，通过报警以及将异常节点的信息发送到护士终端节点的方式，通知医护人员及时处理。
最后，分别测试了系统中各个节点的功能，并检验了系统的整体运行效果。实验表明，系统的各个节点在功能上能够满足实际需要，系统运行稳定可靠。运用到实际医疗卫生领域中，可以提升护理人员的工作效率、减少护理人员的劳动负担、缓解护理人员的工作压力。而且结构简单、功耗与成本低、性能稳定、易扩展，具有一定的实际应用价值。
In recent years, with the sharp increasing in our population and the relativelyscarce in medical resources, the medical burden of the society has significantlyincreased. More than95%of the hospitalized patients will adopt the way of theinfusion treatment. However, there are many defects in the traditional way of infusion:such as the infusion rate is not enough accurate, and the abnormal situation is difficultto timely deal with.
According to actual demands, a transfusion monitoring system is designed basedon the wireless sensor networks. The system is a distributed system, which isconsisting of PC and the nodes of a number of different functions. Each node transmitsthe data by the wireless sensor networks, which is built on the ZigBee technology. Andthe coordinate node transmits the data to PC by Internet. The system uses themeasurement of infrared optoelectronic technology to measure the speed of infusion,transmits the transfusion information of each monitoring terminal node to the PC, andmonitors each terminal node on real-time. When abnormal accidents happen, PC willnotice the health care workers to timely deal with through the alarm and send abnormalinformation to the terminal node of nurses.
Finally, the hardware and software of the system are tested. The experimentsshow that the system can improve staff productivity, reduce labor intensity of healthcare workers, and reduce the working pressure of the health care workers. Besides, thesystem has a simple structure, low power consumption and low cost, stableperformance, easy to expand, and some practical value.
