doc.: IEEE Submission May 2008 Gu Youn Kim, InfopiaSlide 7 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. 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. Bluetooth GlucoMeter

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 GlucoCellphone

doc.: IEEE Submission May 2008 Slide 12 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. Needs of Continuous Glucose Monitoring Gu Youn Kim, Infopia

doc.: IEEE Submission May 2008 Slide 13 Continuous Glucose Monitoring System 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. Insulin pump (Medtronic) Gu Youn Kim, Infopia

doc.: IEEE Submission May 2008 Slide 14 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.
