An artificial pancreas developed by Boston researchers has been shown to monitor blood sugar and deliver both insulin and glucagon to help patients achieve near-normal blood sugar levels for more than 24 hours.
The artificial pancreas, tested at Massachusetts General Hospital in Boston, is made up of a glucose monitor, two pumps and a laptop. It is intended to better mimic the body's natural mechanism of controlling high and low blood sugar.
A computer program works as the brain of the device to constantly analyse blood sugar and calculate when diabetics need a dose of insulin or glucagon.
A similar system was tested by British researchers on 17 children and found it kept their blood sugar levels within the normal range for 60% of the time.
The Juvenile Diabetes Research Foundation has teamed up with Johnson & Johnson's unit Animas and DexCom Inc to develop and test the artificial pancreas system, according to Reuters.
