Artificial Pancreas Dials Up Smartphones
7/1/2013

Trials will take data from a glucose sensor (1), send it to a monitor (2), and then to a smartphone (3), which will determine actions and send them to a pump (4).

A matter of trust

Are you ready to trust your glucose level to a medical electronics company and the reliabiloity of a set of chips, algorithms and batteries?

If I needed it, I'd certainly be willing to give it a shot. Certainly medical technology is failable (I know someone that had a replaced hip recalled), but enough of it works quite well to make the odds worth it in my mind.

I think this will ultimately mean more reliability- not less.

Yes, why not? I think such a artificial pancreas is not more dangerous than a cardiac pacemaker. And medical devices have to guarantee various safety standards like IEC 61508. But I can not imagine to wear such a device at bedtime or during sporting activities like jogging.

The problem is the accuracy of the passive glucose sensor device. AFAIK none of the ones currently available are accurate.

That's what Pritchard thinks of the closed-loop artificial pancreas. I'd love to hear predictions from anyone else working in the field.

That's a very good question Rick. I find it interesting that the phones won't need FDA certificiation. I understand there are a lot of gripes about the FDA certification process, but this may be a good illustration of why that process is in place. It's one thing to be annoyed about dropped calls or your phone freezing up, but if your health depends on it working properly, seems like there could be quite a reliability gap between different models.

Pumps are already controlled via bluetooth

I am a Type 1 and took 4-5 shots per day for 20 years, til I got on a pump 10 years ago. Now my glucose meter is linked via Bluetooth to the pump and it has been very reliable, using it 24/7.  I often thought about the security though and having someone be able to adjust my pump/insulin without my knowledge.  The algorithm for proper insulin injection has to be akin to navigating the Voyager 1 at the edge of the solar system.

Thanks for chiming in Nick.

I assume your monitor signals you to manually release insulin through the pump--is that correct? Still, pressing a button 4-5 times a day has got to be so much better than as many injections.
