Evaluation of monitoring system for removing IV needles using RFID

This paper suggests a monitoring system for removing intravenous injection (IV) needles by patients using radio frequency identification (RFID) technology. In our proposed system, an RFID tag is attached to each tape for securing an IV on arms of the patients. In addition, some reader antennas are set at the bottom of the mattress pad. If the patients remove their IV needles, the communications between the RFID tag and the reader are stopped because the IC chip is come off the RFID tag. Therefore, removing IV needles are detected by whether the RFID tag can communicate with the reader or not. For our proposed system, the tag antenna and the reader antenna are designed and the characteristics of the proposed antennas are calculated. In addition, the communication area between the proposed RFID tag and the reader are measured by use of an examinee. The results show that our proposed system can detect removing IV needles.
