It’s November and Cellnovo, the latest insulin pump supplier in Australia, has finally started supplying pumps. Their consumable products appeared on the NDSS register in an update on the 1st of November, which means that users can now start using their products. As I wrote last month, Cellnovo had initially expected to have this available on …
Here’s a Medtronic 640G sitting on top of the box it came in. But why is the photo on the box of a different pump? Notice the reservoir cap in the upper left of each. The pump on the left has a longer black extrusion sticking out of the pump, whereas the one on the right …
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 …
Blood glucose meters are an essential tool for anyone with diabetes. Even those of us using Continuous Glucose Monitors need to manually check every now and then (e.g. to regularly calibrate the CGM). I’ve used many different meters over the years, but this isn’t going to be a history lesson. It’s more about some of today’s …
“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 …
