Closed loop system for diabetes (Artificial Pancreas)
OHSU # 1521
“Analyte sensing and response system for a closed loop “Artificial Pancreas” system”
A family of 2 issued patents describing methods to calculate delivery of glucagon.
US 7,433,727 Implantable device for monitoring changes in analyte concentration Method to calculate glucose values (ZMAD) when there are multiple signals coming in from many redundant sensors. ZMAD uses a Z-statistic, median of absolute deviations, and leads to increased accuracy vs the use of a single sensing unit. DIV of 5,711,861.
US 8,114,023 Analyte sensing and response system Use of an algorithm that allows effective closed loop (artificial pancreas) control of glucose in persons with diabetes. This method is known as the fading memory proportional derivative control method.
