Some insulin pumps (which are *not* implanted but can be worn under clothes) can report their insulin usage by a wireless link, which is more frequent and can update the monitoring database without human error.
But the app is coded in Java and needs Internet Explorer, although no one knows why.
But the link is not line of sight, does not require user authorisation (like inserting a tag) and uses the unlicensed radio band at 900Mhz
It allows remote adjustment of flow rate and pump activation possibly because *some* users are children (whose insulin needs presumably vary too wildly to be adjusted any other way). This *might* explain why the alarm and vibration warnings can be shut off. Too distracting for the little darlings) and *some* users might have a wireless insulin monitor (from the same company?) which could update pump settings.
Maximum flow rate on the pump would require 200 (c3 hours) mins to dump the whole reservoir. If you wear it while asleep or while driving you might not notice it or be unable to do something about it. So do diabetics wear them to sleep?
Insulin tolerance amongst diabetics varies by an order of magnitude.
This product has been on the market since at least 2006 and possibly as early as 2001 which predates Stuxnet but not the case of the radiation machine whose faulty software dosed patients with 10x the set dose, and a few other cases of embedded systems working incorrectly.
European rules appear to say that since there are so many other ways to tamper with the insulin supply the mfg have a get out of jail free card.
The combination of security-by-obscurity (*despite* the fatal consequences to patients *if* someone tampers with the product) coupled with the circular logic of only-trusted-devices-will-update-the-settings-because-only-trusted-devices-know-how makes this a crime waiting to happen (it would *not* be an accident), always assuming it has not *already* happened.
BTW I first read about "artificial pancreas" research using pumps and an optical sensor in the late 1970's. It needed blood vessels *very* close to the surface to get a clear reading so you
had to "kiss" it. Not really convenient for update rate of every 10 mins.
Despite *huge* advances in MEMS, DSP, stem cell and genetic modification we still seem no closer now than we did then to dealing with Type 1 diabetes. Type 2's best bet seems to be trying to stay on a 900Kcal/diet to shock their cells back into insulation production and reception.
