This makes me think we should be asking/posting lot #s. Those of us with issues have the same lot# of supplies?

We have thought of this too. If you call medtronic to report a problem - make sure you give them the lot number of the infusion set and reservoir - EVEN if they don't ask you for it (which they should).
THANK you all for your excellent posts!
Much appreciated!

I have gotten my first no delivery alarms ever several times in the past month. I have 9mm quick sets with the longer tubing and have noticed that its no longer smooth but has a rough texture. Its been several boxes and my cde at the dr's office says I am not the only one at their practice to have that. I swear my last box is full of dull needles also cause dang they hurt going in. No other differences other than that.

Hi, Jen: Over the five years we have been dealing with pumping, we did have problems on the Animas pump and I assumed it was a problem with the piston. With Minimed, I have noticed recalls at least twice due to malfunctioning batches of Quicksets. These sets are very popular so I wonder if it is a problem with the sets. We have always used sils and if she swtiches will try the Mios because I don't trust the Quickset at this point. P.S. This could be easily trouble-shooted if the pumper were willing to try the Rapid-D set because with a needle set they would be getting the insulin and you could see if it is a pump malfunction. Minimed will help troubleshoot pump malfunction but if in doubt, I would switch out to a new pump. MM will replace.

I have had none of the above except for one no delivery alarm during priming- that was caused by me not seating the tubing on the reservoir correctly and the needle didn't pierce the septum, and wouldn't allow it to prime. This was user error, and quickly corrected once I twisted the tubing on correctly.

No delivery--only on a prime. I reset the cartridge and it works fine.
None of the others have occured.

One thing I will add: I often notice bubbles in the cartridge a couple of days into a cartridge. I know they were not there when I filled and primed. I complained about this at another site, and was pretty much told I didn't know what I was doing; the O rings will not allow air in from the bottom. I beg to disagree. I have had cartridges that got a lot of air bubles--not champagne size either. I have called MM but they also think I am nuts.

Have your partients check the cartridge occasionally for bubbles. They can cause a real high BG.

I thank you for mentioning air bubbles, T1F....I forgot to mention this in my response . I wish I could resolve the problem , even if I check regularly and get rid of the bubble ..I seem to miss some ( during the night ) !
I am back to checking fasting basals and these bubbles are getting in the way , so to speak .

Yep, bubbles are not a good thing!

We instruct our pts to check for bubbles and it is part of our troubleshooting hyperglycemia guide. But the question is why is there so much air in the reservoir and tubing??

I've had two "NO DELIVERY" alarms at the time of priming and I had to change out the sets. One "MOTOR ERROR" alarm and I called Medtronic for help. I've been getting a few reservoirs that aren't working properly with the rubber seal. I have been getting highs but, I just figured I didn't count my carbs correctly.

Hi Jen,
My 6 year old daughter has been on a minimed pump for 2.5 years now. We have noticed several instances of extremely high blood sugars after set changes over the last several months. It has really baffled us to where I question whether we are doing something wrong (I know we are remembering to do the fixed prime, but this is the type of thing I keep asking myself). These blood sugars eventually come down, but it takes many hours of giving abnormally large amounts of insulin. Usually the set is working because most of the time the blood sugars will come down without having to change the set (although we do sometimes end up changing the set). I have noticed instances lately where it seems as if the small amounts of insulin do not get delivered (even if it is not a new set), but once her blood sugar is really high, the large amount for the correction does go through (sometimes too much). It sometimes makes me wonder if it is a non-delivery issue, but we do not get an alarm since my daughter takes a fairly small amount of insulin. I have not called Minimed about this because I just assumed it had something to do with what we were doing.

Contact Medtronic and report the problem every time!
Also, may want to make your pediatric endo to be aware and be on the lookout for other pts reporting the same issues. Most of our patients have been dismissing the issue as "user error" too but maybe it isn't?
