ヒューマンエラーの回避に有効なUHF帯パッシブRFID弱電界手術器械認証システム

抄録

Vestigial remnant of surgical instruments in the body is a serious problem. Two dimensional symbol is being used to help manage this problem. However, the symbols have to be identified one at a time, since the symbols are a sort of printed matter. An HF band passive RFID was also proposed. This system also had problems in identifying the signals of a large number of surgical instruments in bulk, since the scope of its identification area was relatively small. To improve the deficiencies of this system, a UHF band passive RFID system was developed. A new low-intensity antennae are also proposed for the UHF band passive RFID system. From experimental results, 50 surgical instruments were identified in less than one second with this new RFID system. This new system will undoubtedly reduce the workload of surgical nurses, while reducing human error in the operating room.
