Presentation Transcript

  1. RFID Patient Tagging and Database System Student: Martin O’Halloran Supervisor: Martin Galvin National University of Ireland, Galway

  2. Introduction • I will first give a brief introduction to the various technologies employed in the project • I will then detail the application itself National University of Ireland, Galway

  3. 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

  4. Overview of the System National University of Ireland, Galway

  5. 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 National University of Ireland, Galway

  6. Substrate Die attach Tag IC Antenna Tag anatomy National University of Ireland, Galway

  7. RFID Tag Structure Antenna Power Supply Memory Cells Control Logic (Finite State machine) Tx Modulator Rx Demodulator Tag Integrated Circuit (IC) National University of Ireland, Galway

  8. Function of an RFID Transponder • Hold a unique identifier • Respond to requests for the data it carries National University of Ireland, Galway

  9. 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

  10. 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

  11. 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

  12. 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

  13. 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

  14. 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

  15. 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 National University of Ireland, Galway

  16. System Structure Tag Number MySQL & PHP Web-server VB Application Search Database for Patient Records Dynamically Generate Web page Display Web Page Get RFID Tag Number Web Page National University of Ireland, Galway

  17. The Complete System National University of Ireland, Galway

  18. The Complete System National University of Ireland, Galway

  19. 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

  20. 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. National University of Ireland, Galway

  21. Conclusions • System has potential applications in many other sectors including: -Airline passenger/baggage tag -Part recall data -Product tracking -Calibration data -Inventory control National University of Ireland, Galway

  22. Questions and Answers National University of Ireland, Galway
