  1. UAE University College of Engineering Graduation Project I THE USE OF BLUETOOTH TECHNOLOGY IN MEDICAL APPLICATIONS Group Members: Mohamad Al-Mourad 200001516 Fahem Zeid Ali Alwan 200000097 Mohammed Suhail 199900257 Abdulla AlAli 199900315 Supervisor: Dr. Mousa Hussein

  2. Overview • Introduction • Bluetooth Main Characteristics • Selecting the Application • System Integration • Market Review • Sensor Module • Microcontroller Module • Bluetooth Module • Standards • GPII Plan • Conclusion

  3. Introduction • Project Objectives • Make a continuous medical monitoring system using the Bluetooth wireless technology • It gives indications and warnings to the user while he/she is practicing his/her normal life

  4. Introduction • Project Benefits • To those who suffer from heart diseases • Can be used in hospitals to give readings on patients’ health • Gives a deeper view to physicians • Effective to athletes • The system could be extended to include the O2%,blood pressure, or body temperature.

  5. Bluetooth Main Characteristics • Bluetooth Objective: • Replaces wires between devices • Be more for personal use • Bluetooth Features: • High data rate • Multi point Communication • High security • Connection to portable devices

  6. Selecting the Application • Field Visits • RAKCC • Sport Department - UAEU • American Hospital – Dubai

  7. Selecting the Application • Industrial • Agricultural • Medical The Medical Application was selected

  8. Sensor Module MC Module Bluetooth Module GUI Module System Integration

  9. Market Review • Medical applications of Bluetooth are promising • Similar products are either: • In R&D • Just launched to customers

  10. Avant 4000

  11. The Sensor Module • What is the Sensor? • A device that measures or detects a real-world condition, such as motion, heat or light and converts the condition into an analog or digital representation

  12. Classification of Sensors • Sensor Application • Agriculture field (moisture or temperature) • Industrial field (clogging switch ) • Environmental field (Measuring toxic hazardous environment and dust sensor ) • Medical field (Measure oxygen percentage of the patient, blood pressure, body temperature, or the heart beat rate ) • Sensor Output • A voltage or current • Analog or digital

  13. Heart Rate Phases

  14. Average Heart Rate

  15. Exercise Effect • Heart size • Heart beat • Stroke volume • Athlete: 100 - 110ml • Untrained individual: 70 - 80ml

  16. The Maximum Heart Rate (MHR) • The maximum number of contractions the heart is capable of producing in one minute • Health zone: 50% to 70% of MHR • MHR varies with age • Another equation by Londeree and Moeschberger

  17. Searching for HBS Devices Some of heart beat sensors available in the internet

  18. Hear Beat Clip Sensor • A simple design found on the internet • Working concept • Composed of the a clip and an amplifier circuit

  19. Simulating the HBS Circuit

  20. Analyzing HBS Circuit

  21. Building the Sensor Circuit • Components: • One phototransistor, one photodiode, and two diodes • Resistors and capacitors • Test board • Power supply • Multimeter • Function generator • Oscilloscope • Probes • LM358 op-Amp

  22. Comparing LM358 and LM741

  23. Testing and Debugging the HBS

  24. The Output on the Oscilloscope

  25. Calculating the Gain and %Error The gain was calculated as follows: The error between the simulated and practical gains was computed as following:

  26. The Microcontroller Module • What is a Microcontroller? • A complete control unit like the computer • Its Function • Store data • Run programs • Perform math and logic functions

  27. Microcontroller Architecture • CPU • ROM • Input, Output devices • Serial, parallel ports • A/D & D/A • Counters/Timers.

  28. Purpose of the Microcontroller • Receive or gather data from sensor/s and prepare them before being sent to the Bluetooth Sensors MCU Bluetooth GUI

  29. Searching For Microcontroller • ATmega16 from Atmel Co., USA • Too advanced and the project doesn't need advanced functionality in the microcontroller • Test board is complicated • Its setup is not ready in the laboratory.

  30. Searching For Microcontroller • PIC Microcontrollers: • The Microchip "PIC" family • Not difficult for a beginner to learn • Powerful

  31. PIC Setup • The MicroCode Studio Software • Microcontroller chip

  32. EPIC Programmer and LAB-X1 Board • EPIC Plus Programmer • LAB-X1 Experimenter Board • Microcontroller test board designed for the PIC family. • The programming will be done by the EPIC Programmer

  33. Programming & Testing PIC16F877 • Writing and Compiling a Test Code: • Program LED_Blink • main:TRISB = 0             ' Configure pins of PORTB as output eloop:     PORTB = $FF       ' Turn on diodes on PORTB     Delay_ms(1000)    ' Wait 1 second     PORTB = 0         ' Turn off diodes on PORTB     Delay_ms(1000)    ' Wait 1 second goto eloop            ' Stay in loopend.

  34. Testing the Microcontroller • To check the output

  35. Bluetooth Module • History of Bluetooth • Bluetooth Working Concept • Bluetooth Layers

  36. History of Bluetooth • Bluetooth technology was originally discovered in 1994 by Ericsson • Bluetooth named after Harald Blåtand

  37. Bluetooth Working Concept • Point-to-Point mode • Point-to-multipoint mode (Master and Slaves) • Ad-hoc piconet.

  38. Bluetooth Frequency • (ISM) Industrial, Scientific, and Medical Band • From 2.4 up to 2.48 GHz

  39. Avoid Interference • Signal Power = 1 milliwatt (weak signal) • It hopes 79 randomly chosen frequencies within a designated range • Bluetooth transmitter changes its frequencies 1,600 times/sec

  40. Data Rates • Bluetooth channel capacity of 1Mbps • Bluetooth sends data at 64,000 bits/sec. in a full-duplex mode • 721,000 bits/sec. in a half-duplex mode

  41. Bluetooth Layers

  42. The Bluetooth Module Selection • Selection Criteria • Compatible with the chosen microcontroller • Having an integrated or built in antenna • Easy to use • Reasonable cost

  43. The Bluetooth Module Selection • Obstacles and Difficulties • Difficulties in purchasing due to availability • Difficulties because the manufacturers usually do not sell directly to the end users • Lack of technical support

  44. Candidates Bluetooth Components LinkMatik from R.F. Solution ROK 101 008 from Ericsson KC21 Bluetooth OEM Module from KC Wirefree

  45. Another Solution (ToothPIC) • Bluetooth integrated with a PIC microcontroller • FlexiPanel serversoftware enables programming easily • It works on computers, PDAs and mobile phones

  46. Standards • Bluetooth Standards • Bluetooth is based on the IEEE 802.11 communications standard • UAE LAB • TTL Standards

  47. GPII Plan • Building each module alone • Selecting another type of sensor • Programming MC Chip and building its circuit • Connecting the Bluetooth • Developing the GUI • Integrating and debugging the system

  48. Conclusion • Project Impact • Environmental • The bandwidth of the Bluetooth is not in the ionization range • Weak Signal, not enough power to effect human body • Social • Gives the patient more independence • Gives the physician more • Economical • Decreases the cost of health treatment

  49. Conclusion • The Goal:Monitoring health in continues and mobile manner • Bluetooth is a personal friendly technology • HBS clip, PIC16F877, LinkMatik will be used • Ready for building the system
