Modification to Medtronic quick set instructions

[Bill Wireman]

Reference steps 5 & 6 in this discussion, when removing the adhesive tape paper in step 5, you may apply a force that will lift the plastic infusion tubing upward on the needle.
Then in step 6 you will again repeat that same process if you pull the cap during the removal process, both of which will cause you problems when inserting the needle into the skin.
The plastic tubing is attached to the tape which is floating on the needle, which is required to remove the needle after the insertion. So, any upward force will pull the plastic upward causing the skin to compress the tubing onto the tapered shaft on the needle compressing the shape which will create a restriction that will affect the insulin flow.
Solution: in step 6 you must press downward on the cap to reseat the tubing on the needle and twist/ rotate the cap until it falls off into your hand, that may require 4 or more full rotations to accomplish this goal.
Note: in step 6, if you reverse the direction of the rotation shown in the picture then that force is the same used to unlock the seal and could result in insulin leakage from the top of the infusion set.

Just to add that my experience of twisting the thin blue cap protecting the needle, using Tandem cannulas, unfortunately didn't work, and I found it far better to pull it straight off as advised at pump training. Others may differ.

If you have a microscope, you may want to examine the plastic after you have removed it from your body to examine the deformation caused strictly by the reaction of pulling the blue cap. The second week of using my 770g with Mimi Med I saw my first blockage error messages from the pump, then technical support suggested I use the slow method of insulin delivery as a course of action. While this helped, the slow delivery did not fully stop my blockage errors. I found after careful analysis of the problem that my solution eliminated my having to use slow delivery and all blockage errors with my pump, 100%. I know for a fact that this simple procedure will work for all users or I would not have recommended it on this forum. Each person is free to make their own decision but don't discount it without examining your tubing before and after trying this procedure. My trainer suggested twisting the cap slightly before it was removed as shown on the directions but did not add to twist until if falls off in your hand and that is what led to my problems with the pump.
