The artificial pancreas has three elements: a glucose sensor, a computer and a device for administering insulin and glucagon. In people with type 1 diabetes, the cells in the pancreas that produce insulin are destroyed and the level of sugar in the blood is uncontrolled.
The artificial pancreas has a device that monitors blood glucose (sugar) levels every five minutes
The glucose level readings are transmitted to a computer that calculates the the body's requirements for insulin and glucagon
Insulin and glucagon administration:
The computer regulates how much insulin (which reduces blood sugar levels) and glucagon (which raises them) should be administered 24 hours a day.
In the study, insulin and glucagon were administered through a catheter in the subcutaneous tissue of the abdomen
