• 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.

• 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.

Continuous Glucose Monitoring System
Glucosesensor
• 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.

• 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.

• 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
