Hacking Diabetes Meters, Towards an Artificial Pancreas

We’ve covered a number of diabetes-related hacks in the past, but this project sets its goals especially high. [Tim] has diabetes and needs to monitor his blood glucose levels and administer insulin accordingly. As a first step, he and a community of other diabetics have been working on Android apps to log the data when combined with a self-made Bluetooth re-transmitter.

But [Tim] is taking his project farther than previous projects we’ve seen and aiming at eventually driving an insulin pump directly from the app. (Although he’s not there yet, and user input is still required.) To that end, he’s looking into the protocols that control the dosage pumps.

We just read about [Tim] in this article in the Guardian which covers the diabetic-hacker movement from a medical perspective — the author currently runs a healthcare innovation institute and is a former British health minister, so he’s not a noob. One passage made us pause a little bit. [Tim] speaks the usual praises of tech democratization through open source and laments “If you try to commercialize [your products], you run up against all sorts of regulatory barriers.” To which the author responds, “This should ring alarm bells. Regulatory barriers are there for a reason.”

We love health hacking, and we’re sure that if we had a medical condition that could be helped by constant monitoring, that we’d absolutely want at least local smart-phone logging of the relevant data. But how far is too far? We just ran an article on the Therac-25 case study in which subtle software race conditions ended up directly killing people. We’d maybe hesitate a bit before we automated the insulin pump, but perhaps we’re just chicken.

The solution suggested by [Lord Ara Darzi] in the Guardian piece is to form collaborations between patients motivated by the DIY spirit, and the engineers (software and hardware) who would bring their expertise, and presumably a modicum of additional safety margin, to the table. We like that a lot. Why don’t we see more of that?
