Make sure when removing the blue protective sleeve on the minimed quick set that you have rotated the cover 360 degrees until it has freed and will fall off in your hand. If not, then, when you remove the cover will force the needle back into the sleeving then compress the plastic tubing down to the diameter of the needle, as the needle is tapered on the end. If it pulls back to far then the tubing can bend over when inserted. The bend in the tube can be the result of the insertion at an angle where the needle is pushed thru the tubing. Note: when this happens it will cause pain and bleeding during the insertion. So, anyone removing the quickset to see the end of the tubing rolled back, this is what may be causing the problem. The needle blocks any tissue from entering the sleeve during insertion, although, I have seen some blood under the microscope in the tube, but it doesn't affect the insulin flow. Visually, if you remove quickset and do a test insulin bolus it will not show an error, but with the combination of the restriction combined with the tissue is enough to create the blockage error. 99.9% of the bends you see are caused by belt/clothing rubbing, impacts or loose tape from body oils or sweat. I am now marking a line on the blue sleeve before rotation, testing at 90, 180, 270 and finally at 360 degrees before the cap disconnects so as to not cause the needle to recede. This is a test you can all do to verify the symptom mentioned, but don't pull hard just lift the infusion set by the cap to see if still attached.

bwireman, thank you for your post. I believe the "cautionary tale" posts are among the most helpful we can have here. I hope you learned this information in a way that was not too injurious.
