Figure 1: Schematic illustration of an artificial pancreas.
(A) A glucose sensor (black rectangle) measures interstitial glucose levels and transmits information into a control algorithm within a handheld device (red box). The algorithm modulates subcutaneous delivery of a rapid-acting insulin analog via an insulin pump (blue box in pocket). Communication between the glucose sensor, control algorithm and insulin pump is wireless.
(B) The artificial pancreas system replicates the normal role of the beta cell.
