2. Overview of presentation • u-Healthcare Systems • Glucose Monitoring Systems • Continuous Glucose Monitoring System • Conclusion Gu Youn Kim, Infopia

3. u-Healthcare Systems • Healthcare systems measure • Blood pressure and pulse, ECG, Glucose • Healthcare is a part of WBAN. WBAN DATA COLLECTION CARE TEAM FOR PATIENT VITAL SIGNS MEASUREMENT Gu Youn Kim, Infopia

4. WBAN devices • Blood pressure - Patient monitoring and automatic emergency response, sport apps • Glucose meter - Diabetic patient monitoring • Weight scale – patient’s weight monitoring • Body temperature – patient’s body temperature monitoring • ECG - Remote patient monitoring, Sporadic Heart abnormalities identification Gu Youn Kim, Infopia

5. Glucose Monitoring Systems Gu Youn Kim, Infopia

6. Glucose Monitoring Systems • Categories • Indoor : potable system with networking capabilities • Indoor/outdoor : cellphone with glucose module In Door WPAN GlucoMeter Indoor/Outdoor GlucoCellphone Gu Youn Kim, Infopia

7. GlucoMeter • A patient tests the blood glucose level with GlucoMeter. • GlucoMeter sends the results by using Bluetooth. • Bluetooth gateway(PC or cellphone) relays the results to destination. Bluetooth 1.Insert test strip. The code number is automatically entered. 2.Select activities related to the test result by press button. 3.Apply sample until confirmation window is comple -tely filled before the meter begins to count down. 4.Test results in 3 seconds. 5. Pressing send button, the results are transmitted to PC or cellphone. Gu Youn Kim, Infopia

8. GlucoCellphone • Cellphone with glucose module • The cellphone identifies the module and executes diabetes program. • It sends the results to destination. 1.Insert glucose check module to mobile phone. 2. Diabetes program is automatically executed. 3.Insert test strip. 4.Test results in 9 seconds. 5. Send the results to destination Gu Youn Kim, Infopia

9. Analysis of Medical data • Doctors review, chart and consults online. • Trend graph, Graph by hour, Prescription Gu Youn Kim, Infopia

10. System Specifications of GlucoMeter Gu Youn Kim, Infopia

11. Continuous Glucose Monitoring System Gu Youn Kim, Infopia

12. Needs of Continuous Glucose Monitoring • Increasing number of people with diabetes • To improve therapy and hypoglycemia awareness; • Continuous glucose monitoring can reduce hemoglobin A1C levels when compared with fingersticks alone, which in turn can reduce the risk of longterm health complications. • To improve the REAL-life decisions through new insights on the impact of daily activities on the glucose control. Sung Dong Lee, Infopia

13. Insulin Pump and Glucose Sensor Glucose sensor • Insulin pump may be a transmitter of the implantable glucose monitoring system. • The insulin pump transmits data wirelessly to a dongle connected to a computer. • Data from sensor and insulin pump can be utilized by Diabetes' therapy management software solutions. (Medtronic) Insulin pump Sung Dong Lee, Infopia

14. Working procedure • The sensor is placed on the back of upper arm or abdomen, and is held there with a special adhesive. • A tiny filament 5mm long (as thin as several strands of hair) goes just under the skin. • The transmitter attached with the sensor sends glucose readings to the wireless receiver. • The receiver stores all glucose readings, and it gives an accurate changes of the glucose. Sung Dong Lee, Infopia

15. Networking Scenarios • Scenario-1 : Point-to-point • Sensor  Monitoring system • Sensor  Monitoring system  Gateway Internet • Scenario-2 : Point-to-Multipoint • Assume environment of in-body and on-body sensors/actuators • Sensors & Actuators  Gateway Internet • Sensors & Actuators  WBAN coordinator  Gateway Internet Sung Dong Lee, Infopia

16. Issues • Networking • Automatic node detection, network configuration and service discovery • We need point-to-multipoint control. • Medical devices under regulatory : Point-to-point control • How to solve ? • How to grantee the integrated controller ? • System reliability may be related to safety. • Low Power • Extremely low power consumption • Duty cycling • Flexible & efficient sleep modes • Fast set-up time • Battery • Long standby times for portable device • Very small size Gu Youn Kim, Infopia
