[Diabetes-Talk] FW: [Tech-VI] t:connect iOS app for insulin pump could kill users, says FDA

Thu May 16 18:31:46 UTC 2024

Hi, 

I just met with a Tandem rep this week to go over the Tandem Mobi which just might be my next pump. I asked the rep about the software issue and she said it has in fact been corrected. The issue was quickly fixed and she said that regarding current software there are many alerts and checks that should prevent a situation like that from happening. The issue was the software was somehow draining the battery on the pump very fast.

I'm impressed by the Mobi and it appears  to me to be completely accessible (at least the items I went over with the rep). Voice Over works well with their app and allows control over carbs or units of insulin to be issued. Loading the cartridge with insulin, etc also appears to me to be completely doable by a totally blind person.

I am still going to meet next week with Medtronics to see the 780G pump again and will then make my decision.

Eileen

Sounds like overkill to me, pardon the punn. Most Tandem users I know got the notice weeks before and the fix was already out there. If you're aware of what your pump is doing, you'd know what was happening. Recall? Sure. Of course, but I don't think the drama was necessary or very responsible on the part of the FDA.
Just my dollar's worth.

This is because their pancreas makes little to no insulin, meaning sugar is unable to be passed from the blood to cells. This causes sugar to build up in the blood-stream, which can be life-threatening.

This cycle intermittently repeats, which leads to excessive Bluetooth communication that may result in pump battery drain and may lead to the pump shutting down sooner than typically expected.
