Design of Dual Mode RFID Antenna for Inventory Management and IV Fluid Level Warning System

Abstract

Radio frequency identification (RFID) readers are powered RF devices that communicate with an RFID tag to read necessary information. Using this capability, a dual use system for short distance inventory management and moderate distance automatic warning system for low intravenous (IV) fluid levels is designed. The RFID is affixed on the IV drip bag; the fluid in bag affects the antenna transmission distance by fluid dielectric conditions. This allows for two different operational modes (moderate and short distance). For pharmaceutical management, a handheld RFID reader can be used for short distance application. Another stationary RFID system can serve as a warning system for long distance application such as hospital care.

Compact UHF RFID balun‐like integrated tag antenna for long range detection of water bottles

“…Similarly, a conformal tag antenna with a reading range of 3.5 m [32,41] was proposed for a smart blood repository system to track blood bags [33]. Furthermore, RFID tags were proposed for liquids such as intravenous (IV) [34,35], shakes, wine, and orange juice [36]. Similarly, a slot enabled near body tag was proposed in [37].…”

A Novel Approach of Controlling Stoppage of Drip Infusion Using Image Processing on Raspberry PI Platform

“…There are two methods of doing so, namely using an infusion pump and using drip IV (intravenous) delivery that has been used since 1944 [1]. Since the first use, there are many methods implemented to monitor the flow of the infusion fluid by measuring the weight, counting the number of drops, using ultrasonic wave TDR, infrared detection, and RFID [2][3][4][5][6][7][8][9][10].…”

“…Further, Ting et al [7] studied the electrical characteristics of how the RFID tag is suitable to echo the signal from the RFID reader and how the reader should detect the signal. They use two different modes of application, one for the low fluid warning and the other for the inventory control.…”

Low-Cost Inkjet-Printed RFID Tag Antenna Design for Remote Healthcare Applications

“…However, the proposed solution is costly with large dimensions. Moreover, another solution designed for the IV solution also consists of a microstrip type tag with relatively large dimensions [20].…”
