  • RFID Patient Tagging and Database System

    1. 1. RFID Patient Tagging and Database System <ul><li>Student: </li></ul><ul><li>Martin O’Halloran </li></ul><ul><li>Supervisor: </li></ul><ul><li>Martin Galvin </li></ul>
    2. 2. Introduction <ul><li>I will first give a brief introduction to the various technologies employed in the project </li></ul><ul><li>I will then detail the application itself </li></ul>
    3. 3. Project Goal <ul><li>Identification of the Patient through an RFID wrist tag </li></ul><ul><li>Storage of Patient Medical details in a web based database </li></ul><ul><li>Retrieval of patient information from the database using the RFID tag number </li></ul>
    4. 4. Overview of the System
    5. 5. RFID <ul><li>Two components: -RFID Transponder </li></ul><ul><li>-RFID Reader </li></ul><ul><li>Every object has an RFID transponder, holding identification information </li></ul><ul><li>The reader retrieves the identification information from the RFID tag </li></ul>
    6. 6. Tag anatomy Substrate Tag IC Antenna Die attach
    7. 7. RFID Tag Structure <ul><li>Antenna </li></ul>Power Supply Tx Modulator Rx Demodulator Control Logic (Finite State machine) Memory Cells Tag Integrated Circuit (IC)
    8. 8. Function of an RFID Transponder <ul><li>Hold a unique identifier </li></ul><ul><li>Respond to requests for the data it carries </li></ul>
    9. 9. RFID Reader <ul><li>Interrogate tags via RF communication </li></ul><ul><li>Consist of a RF module, a control unit, and a coupling element </li></ul><ul><li>They have a secondary interface to communicate with a host system </li></ul><ul><li>Reads tags located in hostile environment and obscured from view </li></ul>
    10. 10. RFID Conclusions <ul><li>Each patient will have an RFID tag </li></ul><ul><li>The RFID Tag will hold a unique identifier </li></ul><ul><li>This identifier will be retrieved by the RFID reader </li></ul>
    11. 11. Web Based Database <ul><li>The web-server takes the RFID tag number, searches the database and returns the patient details </li></ul><ul><li>MySQL – Database that holds the patient information </li></ul><ul><li>PHP – Database Querying script </li></ul>
    12. 12. MySQL <ul><li>Standard database programming language used for creating databases </li></ul><ul><li>It provides methods for updating and retrieving information </li></ul><ul><li>The information is divided into logical units called tables </li></ul><ul><li>The tables include personal information, medical information and nurses’ observations </li></ul>
    13. 13. PHP <ul><li>It’s a embedded scripting language (encoded in HTML) </li></ul><ul><li>Scripting language interacts with databases and dynamically generates web pages </li></ul><ul><li>Invokes SQL commands to interact with database </li></ul>
    14. 14. Visual Basic <ul><li>Functions: </li></ul><ul><li>-Interface with the RFID reader </li></ul><ul><li>-Display the results of the SQL database queries </li></ul><ul><li> (dynamically generated web pages) </li></ul>
    15. 15. Visual Basic <ul><li>The MSComm control handles the communication with the RFID reader </li></ul><ul><li>Visual Basic’s Web Browser component handles the displaying of the PHP and HTML pages </li></ul>
    16. 16. System Structure MySQL & PHP Web-server VB Application Tag Number Search Database for Patient Records Get RFID Tag Number Display Web Page Web Page Dynamically Generate Web page
    17. 17. The Complete System
    18. 18. The Complete System
    19. 19. Functionality of the System <ul><li>Update and retrieve patient personal details </li></ul><ul><li>Update and retrieve patient medical details </li></ul><ul><li>Upload and retrieve patient multimedia data such as x-rays, pictures, etc. </li></ul><ul><li>View previous medical details </li></ul>
    20. 20. Conclusions <ul><li>System successfully merges the technologies of RFID and web-based database systems </li></ul><ul><li>The RFID tag provides a secure and robust method for holding the patients identifier. </li></ul><ul><li>The web-based database allows for the centralisation of all patient records. </li></ul>
    21. 21. Conclusions <ul><li>System has potential applications in many other sectors including: </li></ul><ul><li>-Airline passenger/baggage tag </li></ul><ul><li>-Part recall data </li></ul><ul><li>-Product tracking </li></ul><ul><li>-Calibration data </li></ul><ul><li>-Inventory control </li></ul>
