A study for total automatic management of ME equipment by using passive RFID tag.

UHF频段(920 MHz频段)的无源RFID标签系统具有很高的性能。通过使用该系统，可以在远离阅读器天线的情况下识别医疗人员。本研究通过一些实验，分析了其在医院ME设备位置管理中的优势。在ME设备维修中心、病区库存室和病区治疗室测量了检测ME设备的标签的真实识别面积。在实验结果中，认为识别面积足以在所有情况下检测到ME设备。还认为，由于零点出现在建筑物结构的特定点处，因此零点位置是可以预测的。利用标签系统和医院网络系统实现了医疗设备的远程跟踪系统。并对电磁安全进行了分析。在实验结果中，确定了几类ME设备的安全等级。

UHF band ( 920MHz band ) passive RFID tag system has high performance. By using the system, medical individuals can be identified away from the reader antenna. In this study, its advantages are analyzed by some experiments for ME equipment location management in hospital. Realistic identification area of the tag to detect ME equipment are measured at ME equipment maintenance center, stock room in sick ward and treatment room in sick ward. In the results of experiments, it is considered that the identification area is enough to detect the ME equipment in all cases. It is also considered that null point location can be predicted, since the null point appeared at specific spot by structure of the building. Remote tracking system for the ME equipment is realized by using the tag system and hospital network system. Electromagnetic safety is also analyzed. In the result of experiments, the safety level for several category of the ME equipment are confirmed.
