see if u can't just get new equipment ordered by dr.
or go off the pump and take care of it thru the day
or look around and see if u can find a mfg offering free equip if u switch over
good luck
If your sites are bending, it is not the pump that is the issue, it is you. I have the same pump and have never had any issues with it. You are obviously not taking better control of your diabetes, and testing often enough, because it takes more than missing insulin for a moment to hit DKA. I suggest you start by checking more often, and if the pump is still under warranty, medtronic will send you a new one, to stop the issue with no delivery. I have had them for almost 10 years and have never had an issue with them not working me whenever there has been an issue.
