Recently I posted an analysis of the behaviour of various AAA batteries in my insulin pump. Second instances of some battery models have been completed, so we get a chance to review the initial conclusions. Here’s the graph with just the duplicated battery types: That’s still quite busy, so next we’ll look at just the …
Various events are being held around the globe to mark November 14: World Diabetes Day. At Sunshine Hospital in Melbourne’s west, there will be a T1D patient peer support event on the 14th entitled “How far away is the artificial pancreas?“. There will be three main speakers: two involved with the current Australian trials of the Medtronic …
A closed-loop system can only be as good as the CGM that’s feeding it. Keeping that CGM accurate is essential! I’m currently running an experiment where I’m using a Dexcom G5 sensor and a Libre sensor concurrently to compare the behaviour and results. Mostly they track fairly closely, although at first glance the Libre does …
“My friend’s kid has one of those.” Not an unusual reaction if I describe my closed-loop insulin system to someone without diabetes. They’ve heard about insulin pumps, and not unreasonably assume that they take a lot of the work away by automatically adjusting the insulin dose as required. Because that seems an obvious application of …
In my closed-loop pump system, the OpenAPS rig (a tiny Linux computer) communicates with the Medtronic Veo 554 pump every few minutes via radio. This works great, but it does put extra load on the pump’s AAA battery. So the batteries don’t last as long as in a non-looping pump. These AAA batteries are smaller …
Insulin pumps are life-sustaining devices that we live with 24 hours a day, so we become quite invested in them. We all live different lives, and our needs (and tastes) in insulin pumps vary. With this week’s announcement that Animas has shut down in the US/Canada, there are obvious clouds on the horizon for Australian …
