The control algorithm could be included directly into a continuous subcutaneous insulin infusion or to an external device capable of communicating in real time with the insulin pump and a continuous glucose sensor. The algorithm is based on rules and forecasting techniques. Its operation is customized for each patient allowing maintain blood glucose levels within normal limits.

Its use will prevent low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia), especially during night, which is when patients have more difficulty recognizing the symptoms.

“Automatic algorithm to maintain glucose levels within normal limits and minimize the risk of hypo-and hyperglycemia”

• People with diabetes who use continuous insulin pumps generally have great freedom to adjust insulin to their routines and unexpected events, such as changes in mealtimes, food intake and quantities, physical exercise, disease states, stress, etc. all of which affect glucose levels. 
• This fine adjustment of insulin requires knowing the blood glucose levels almost continuously but in a minimal invasive way. Nowadays, it is possible because there are commercial solutions which measure glucose every few minutes with a sensor implanted in the subcutaneous tissue. 
• However, it is not easy for a patient to have a normal and quality life, if he must continually interpret his blood glucose profiles and make decisions about programming the insulin pump. 
• The solution is the use of algorithms that can automatically control the insulin pump and to prevent hypoglycemic events, which is the greater risk in insulin treatment. 
• Also it is important to avoid a continuous hyperglycemia over the years which could produce the loss of quality of life due to renal diseases, blindness, or amputations.

"The artificial pancreas can prevent and avoid hypoglycaemia and the occurrence of complications in the future due to poor metabolic control"

The control algorithm has been evaluated at the Sabadell Hospital with a group of patients during the night and has managed to increase by 340% the time in normal glucose levels (80-110 mg/dl), therefore avoiding hypoglycemia during the night.
