My x2 squeaked while filling a new cartridge today, first time. Not sure if this is something that is common or should I call tech support? I’ve had my animas vibe/ping for 13 years and it never squeaked with that rotating screw piston thing. Thoughts?
You might call tech support anyway but the x2 has no piston thingy like the Animas did. It is a completely different insulin delivery system based on air pressure. There was a complete explanation of the x2 delivery system made on this forum in the last 6 months. You may wish to look it up. Did you mean that this was your first time filling a cartridge? My x2 squeaks when filling the tubing each and every time. It is somewhat like a wheezing in-breath that it takes every few “puffs” out. Normal. That’s what it does.
Thanks yes that is it. Never did it before, now I know.
The Tandem cartridge has an empty plastic bag inside, and when you first start filling it with insulin it makes a sound as the plastic opens up. To me it sounds more like expanding plastic than a squeak.
If you reuse a cartridge it doesn’t make the sound. You can confirm that by saving a syringe and just injecting water in an old one before you throw it away.
