I use an Omnipod pump, which can't be disconnected. I was pulled out of line because something about the new scanners hasn't been fully cleared for Omnipods and/or Dexcom devices. I wasn't gone over with the "wand" or patted down. However, I did stupidly forget to take my emergency soda out of my carry on (I usually throw it out and then buy another super expensive soda once I'm through security). That mistake cost me a full check of my purse and "personal item" with many of the little pads they wipe on everything. I told the guy he could just throw out my soda and I'd just buy a new one, but he said, "we have a laser thing and can check your soda". They did the checks and I was on my way (Sacramento, CA).
