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.
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

Analysis of Medical data

• Doctors review, chart and consults online.
• Trend graph, Graph by hour, Prescription

Continuous Glucose Monitoring System
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.

13
Continuous Glucose Monitoring System
Glucose sensor
(Medtronic)
Insulin pump

• 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.

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.

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

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
