I thought I'd post what has been my experience with getting through airport security now that I'm wearing the OmniPod. The same exact procedure played out in the following airports: Minneapolis, Raleigh and Nashville, so I'm fairly certain it's happening this way at many airports across the country.
Personally, I choose to not announce to TSA that I am wearing medical devices. My personal approach to getting through security is as follows:
-Place both my DexCom receiver and OmniPod PDM in the tray along with all my other belongings
-Say nothing to TSA
-Proceed through either metal detector or full body scan like everyone else
If going through old school medical detector - neither the DexCom sensor or OmniPod gets picked up and I continue on as if nothing occurred.
If going through full body scanner (the one where you stand with feet spread and arms up as a thing whirls around your body) - the DexCom sensor never gets picked up, however, the OmniPod (and I'm wearing the new, smaller pods) does register on their computer screen.
After getting out of the machine I will tell TSA I have diabetes and I am wearing an insulin pump. The TSA agent then immediately walks me over to a device that tests the pump to make sure it's not a bomb. This test is performed by first having me touch the pod with my bare hand. Then the TSA agent wipes my hand with a dry, white, small square piece of cloth. This cloth is then put into a machine and about 30 seconds later a message will pop up on the screen saying "not an explosive" <---thankfully, this has always been the result. I am then free to go back and get my belongings off the belt. This entire experience takes less than 5 minutes.
If you've not flown with the OmniPod, just be prepared that this might happen to you, but it's no big deal (to me, at least).
