Summary:
Recently, wireless communication technology has been expected to apply various fields. RFID system is one of these technologies. Mainly this system is used for management such as entry and exit of important facilities or logistics in warehouse. Also, in recent years, the healthcare system and the medical management have become very active research areas. These areas have been expected to be applied various technology. One of this is managing surgical instrument system using RFID system. With this system, details of surgical instruments can be accurately managed, for instance history of using or disinfection. In addition this system may prevent some artificial medical accidents. Moreover, this system may reduce the load of staffs in the hospital. The antenna is sensitive to the environment, such as water, metal and temperature. In case, the tag antenna is attached on the object, the antenna characteristics may change. At worst, the antenna can be impossible to communicate. We need to understand precisely the suitability of RFID tag antennas to the metal because the surgical instruments managing system by use of RFID tag antennas which can be placed in the vicinity of the metal. Further, how to attach the RFID tag on the surgical instrument is important. The method is required less harmful for human and heat resistance for disinfection, also that the tag does not come off easily. In addition, since the antenna may be affected not only surgical instrument but also RFID tag attachment tools, we need to understand precisely the suitability of RFID tag antennas to the RFID tag attachment tools. Therefore in this paper, we calculated the change of the antenna characteristics when an RFID tag mount on three positions of the long surgical instrument and an RFID tag is attached with two materials of RFID tag attachment tools.
