Introduction

I will first give a brief introduction to the various technologies employed in the project

I will then detail the application itself

Project Goal

Identification of the Patient through an RFID wrist tag

Storage of Patient Medical details in a web based database

Retrieval of patient information from the database using the RFID tag number

National University of Ireland, Galway

Overview of the System

National University of Ireland, Galway

RFID

Two components:-RFID Transponder

-RFID Reader Every object has an RFID transponder,

holding identification information The reader retrieves the identification

information from the RFID tag

Function of an RFID Transponder

Hold a unique identifier

Respond to requests for the data it carries

National University of Ireland, Galway

RFID Reader

Interrogate tags via RF communication Consist of a RF module, a control unit, and a

coupling element They have a secondary interface to

communicate with a host system Reads tags located in hostile environment

and obscured from view

National University of Ireland, Galway

RFID Conclusions

Each patient will have an RFID tag

The RFID Tag will hold a unique identifier

This identifier will be retrieved by the RFID reader

National University of Ireland, Galway

Web Based Database

The web-server takes the RFID tag number, searches the database and returns the patient details

MySQL – Database that holds the patient information

PHP – Database Querying script

National University of Ireland, Galway

MySQL

Standard database programming language used for creating databases

It provides methods for updating and retrieving information

The information is divided into logical units called tables

The tables include personal information, medical information and nurses’ observations

National University of Ireland, Galway

PHP

It’s a embedded scripting language (encoded in HTML)

Scripting language interacts with databases and dynamically generates web pages

Invokes SQL commands to interact with database

National University of Ireland, Galway

Visual Basic

Functions:

-Interface with the RFID reader

-Display the results of the SQL database queries

(dynamically generated web pages)

National University of Ireland, Galway

Visual Basic

The MSComm control handles the communication with the RFID reader

Visual Basic’s Web Browser component handles the displaying of the PHP and HTML pages

Functionality of the System

Update and retrieve patient personal details Update and retrieve patient medical details Upload and retrieve patient multimedia data

such as x-rays, pictures, etc. View previous medical details

National University of Ireland, Galway

Conclusions

System successfully merges the technologies of RFID and web-based database systems

The RFID tag provides a secure and robust method for holding the patients identifier.

The web-based database allows for the centralisation of all patient records.

Conclusions

System has potential applications in many other sectors including:

-Airline passenger/baggage tag

-Part recall data

-Product tracking

-Calibration data

-Inventory control
