I've been reading this thread all week, besides being a retired newspaper man I'm also a registered nurse with my public health degree, I'm fully retired now but was a certified diabetic instructor for many many years and I'm very familiar with insulin pumps.
As a newspaperman, yes, this is a poorly written article oh, nothing new there, as a RN, an insulin pump simply monitors blood sugar, has a small vial of insulin in it and inserted in the patient is a 25 gauge small rubber catheter to their right or left lower quadrant. It actually injects insulin in accordance with blood sugar.
If they actually made insulin pumps that were affected by ham radio or any kind of RF interference we would have people dropping like flies from either diabetic coma or insulin shock, especially in metropolitan areas.
Karen says she has an issue for a year. Karen is still alive?. Most issues with insulin pumps are user related.
Don't get me wrong, I have seen insulin pump models recalled... Immediately.
Of course we don't have a follow-up on the story and I'm sure we don't have all of the facts.
