In response to your question... I have been on the Minimed pump for almost 2 years and I can tell you that I have experienced your problem quite a few times. The reasons that I have discovered were: 1) the pump is simply not delivering, even though it usualy gives you a warning, sometimes it does'nt. The solution is to change the infusion set. 2) Bad insulin 3) There is a leak in the tube that holds the insulin, this is known as an O-ring leak. I just had this problem last week - my blood sugars were running extremely high and I was taking like 3-4 times the amount of insulin than I usualy do! I noticed liquid in the pump and that it was coming out of the back of the tube, I changed the set and it was still leaking! I googled "problems with minimed pump" and I found a site that discussed this very problem! The site said to throw out that whole box of tubes and use a new box because it means that there is a problem with the molding. I did it and Presto! my pump and sugars went back to normal. If you see liquid in the pump (in the chamber that holds the tube) and you are using a minimed pump it is most-probably the above-mentiond problem. Please write back if you were able to solve the problem that you are having. Good Luck!
