The artificial pancreas is made up of the sensor, a computer programme that calculates how much insulin is needed to keep blood sugar in check, and an insulin pump.The artificial pancreas is made up of the sensor, a computer programme that calculates how much insulin is needed to keep blood sugar in check, and an insulin pump.
The purpose of the trial, run by Dr Roman Hovorka and backed by the Juvenile Diabetes Research Foundation, is to perfect the computer algorithm so the glucose sensor can "talk" to the insulin pump effectively and mimic the work of a normal pancreas.The purpose of the trial, run by Dr Roman Hovorka and backed by the Juvenile Diabetes Research Foundation, is to perfect the computer algorithm so the glucose sensor can "talk" to the insulin pump effectively and mimic the work of a normal pancreas.
Dr Hovorka hopes that after a series of clinical trials over the next two years the device could be used by children in their own homes.Dr Hovorka hopes that after a series of clinical trials over the next two years the device could be used by children in their own homes.

Many diabetics already use an insulin pump - a small device worn outside the body that pumps insulin into the body through a thin tube under the skin - to remove the need for a daily series of injections.Many diabetics already use an insulin pump - a small device worn outside the body that pumps insulin into the body through a thin tube under the skin - to remove the need for a daily series of injections.

In comparison, continuous glucose sensors, the size of a credit card and worn on the skin, read glucose levels on a minute-by-minute basis using a small sensor that is inserted under the skin.In comparison, continuous glucose sensors, the size of a credit card and worn on the skin, read glucose levels on a minute-by-minute basis using a small sensor that is inserted under the skin.
Achieving good blood glucose control dramatically lowers the risk of serious complications such as blindness, stroke and premature death.Achieving good blood glucose control dramatically lowers the risk of serious complications such as blindness, stroke and premature death.
Studies have found that even patients who aggressively manage their disease - measuring their blood glucose an average of nine times a day - spent less than 30% of the day in normal range. The rest of the time, their blood sugar levels were either too high or too low.Studies have found that even patients who aggressively manage their disease - measuring their blood glucose an average of nine times a day - spent less than 30% of the day in normal range.

Trials show patients using continuous glucose sensors spend 26% more time in normal glucose range, and have statistically significant improvements in a measure of longer-term blood glucose control, called HbA1c.Trials show patients using continuous glucose sensors spend 26% more time in normal glucose range, and have statistically significant improvements in a measure of longer-term blood glucose control, called HbA1c.

In Type 1 diabetes the body stops making insulin and the blood glucose level goes very high. This type of diabetes usually appears before the age of 40 and accounts for between 5 and 15% of all people with diabetes.In Type 1 diabetes the body stops making insulin and the blood glucose level goes very high.
