That happened to my son too a lot. And you know what was the problem? We were never teach that when you put the infusion set on the inserter, you must push a little. The infusion may go into a little whole in the inside of the inserter. Best way to find out if it's correct is flipping the inserter down (with the infusion set on it). The infusion should remain on the inserter. We were lucky for almost a year w/out any problem with the quick set but suddenly since february was a bad site after the other. Cannula was bent before it get into the skin, bc the needle was not piercing the skin. |
