...design, a blood glucose monitor signals a subcutaneous device to release insulin and glucagon, which are deficient pancreatic hormones in type 1 diabetics...
...technology depends on an automated software that uses a glucose-control algorithm to determine the appropriate amounts of insulin and glucagon a patient needs, according to Edward Damiano, an associate professor of biomedical engineering at Boston University...
...Most people realize that type 1 diabetics have trouble producing insulin, but what is less commonly known is that they often don’t produce enough glucagon,” said Steven J. Russell, an instructor in medicine at Harvard Medical School who also worked on the project...
Constant glucose-monitoring systems face the problem of a delay between the release of insulin and its absorption in the body. If the body responds too slowly, too much insulin can accumulate and result in hypoglycemia—a worst-case scenario, according to Firas El-Khatib, a researcher at Boston University...
...researchers discovered in that variability in the rate of insulin-absorption is very high—not only across the general population, but also for specific individuals. The versatility of the algorithm in the artificial pancreas allows the device to treat patients with widely differing insulin absorption rates...
