Improvement of monitoring system for removing IV needle

Abstract

In previous study, a monitoring system of removing intravenous drip (IV) needles by RFID is suggested and evaluated. When patients removed their IV needles, this system alerts the accidents to nurses. This paper tries to improve this system by use of improved antennas in order to reduce false-positive. For our proposed system, a tag antenna and a reader antenna are designed. In addition, characteristics of these antennas are calculated. Moreover, our proposed system is evaluated by use of a fabricated antennas and an examinee. From the results, this paper shows a stable monitoring system of removing IV needle.
