Message: <blockquote data-quote="jackwolt" data-source="post: 1243861" data-attributes="member: 329650">I have had three bouts of ketoacidosis and a couple of near misses. Each time I have found that the cannula has not inserted correctly and is lying at 90 degrees between the sticky pad and my flesh. I think I have figured out how this happens:If you pull on the tube to guide it into the nick the whole pad can lift. As you can see, the cannula lifts away from the steel needle and, without support, can bend over. It does not take much of a pull to do this. There is no FLOW alarm as I think the insulin just seeps away through the pad. A possible solution to this may be to make the nick a much deeper slot so that the angle of the tube is not so acute and the cannula would not lift so easily.I have used approx. 650 of these MIO infusion sets (MMT-945) and have only had 1 Flow failure. I had an immediate FLOW alarm and just changed it without any further investigation.Hope this helps.</blockquote>
