Artificial Pancreas, Could It be?

The diabetics now can expect a lot, after a number of researchers in the United States develop an artificial pancreas, a system consisting of insulin pumps and glucose sensors that send insulin for diabetics so they can mimic the original function of the pancreas.

Although the equipment that records the blood sugar of diabetics and automatically deliver precise doses of insulin that was still far from commercial use, the results of research presented at the American Diabetes Association meeting in San Diego showed real promise.

AFP argues, researchers from Boston University and Massachusetts General Hospital to test a system, using glucose monitors made ​​by Abbott Insulet Corp.'s FreeStyle Navigator, and two artificial insulin pump Insulet Corp., which are all controlled by a laptop. That system, designed to better mimic the body's natural mechanism, in controlling blood sugar. Either high or low temperatures. The tool is easily portable to allow the adult type 1 diabetics to get around the hospital and using an exercise bike.
At the end of the study for 51 days, which involves daily exercise, two nights and six meals, all of which affect blood sugar levels of diabetics, six patients recorded blood sugar levels on average in the normal range, with the highest levels of 140.
  1. Automated cannula insertion system
  2. Water tight housing
  3. Insulin reservoir (capacity of 85 to 200 deliverable units) 
  4. Adhesive 
  5. Drive mechanism 
  6. Angled infusion set 
  7. Electronic circuitry for programming insulin delivery and enabling wireless communications 
  8. Power supply (batteries) 
"It's very nice. This is what we call blood glucose close to normal," said Dr.. Steven Russell of Massachusetts General Hospital in Boston who developed the system by Edward Damianio, an expert in biomedical engineering at Boston University.

In another study, a team at the Mayo Clinic diabetics fitted with devices called accelerometers that record the movement and found that moderate exercise also plays a role in glucose. *** [SRI | PIKIRAN RAKYAT 13102011]
