Robotic Pancreas for Diabetics
Check out this article about one man’s quest to put diabetics on auto-pilot. Although all the components are out there, there has been a gap in connecting the dots.
Manufacturers were afraid of liability, academics were bent on achieving perfection, and the Food and Drug Administration was downright jumpy at the thought of letting a computer control a mechanism with life-and-death responsibilities.
Yet most of the components for what researchers were calling an artificial pancreas — an external device the size of an iPod that would duplicate the insulin-secreting and -regulating functions of that organ — were already in place. An insulin pump had been approved back in the late 1970s, and a continuous glucose monitor that read the output of a sensor implanted under the skin was nearing approval. (The first one would hit the market in 2005.) The trick was to connect the two via software, letting the monitor’s information on blood-sugar levels — high or low, rising or falling — serve as the basis for calculating exactly how much insulin to release.
