I have flown since the new screening techniques were initiated. The Tulsa airport has used millimeter-wave technology machines for quite some time, and I go through with my pump w/o any major issues. I let the TSA agent running the machine know that I have an insulin pump on (point to it’s location on my body–I wear the pod so when I fly I try to wear it on my arm so they can see it easily), and when I step through the usually have me wait for a minute while the agent running the booth gives me the “green light” to go gather my stuff. I’ve had them wipe the pod down before and run the swab through the spectroscopy machine (the “sniffer” machine). My most recent flight they also did the thorough pat-down (before it’s just been a local pat-down around the pod, and that’s it). As others have said, the newer, more thorough pat-down was not “fun”, but it was not horrible by any means…and it may have added a whole extra one or two minutes to my quick trip through security–not really an issue to me at all. If everyone in line is getting more thorough pat-downs, then it could slow your travel down and you’d need to leave lots of time for the screening. If not, I would not factor in much additional time, as something as simple as having a pump on you is not going to impede you significantly.
The TSA agents are much more familiar with the tubed pumps (animas, MM, etc) and most of my conversations with them when I let them know that the pod is a pump usually revolve around how different this one looks compared to the others. I don’t think you’ll have any major issues with your MM.
The x-rays that the pump manufacturers request that you keep the pump away from include medical diagnostic equipment, specifically the primary beam of the x-ray. If you’re getting a chest or ankle x-ray, for example, you’d want to remove it from the area being imaged (which any legit radiographer would have you do so that it would prevent artifacts on the image), and just make sure it’s covered with shielding (the heavy apron they should lay over your reproductive organs). If you’re having a CT scan done, I would recommend the same (either wrap it in the lead shielding, as just covering it on one side is useless since the CT unit’s x-ray tube travels throughout the gantry (the “doughnut”) all the way around you, passing x-rays from all sides) OR I would suggest removing the pump for the duration of the scan (which in most imaging procedures on today’s equipment should be <10 minutes from start to finish).
The backscatter machines used in airports provide a much lower total dosage than even a chest x-ray (which is typically a very minimal exposure), and exposing the pump to that level of remnant radiation should not adversely effect it. I would suggest wearing it through the body scanner rather than placing it on the baggage belt though, as the energy and quantity of x-rays emitted by those machines can vary as the agent adjusts the settings to see through more or less dense structures within the conveyor belt. The more dense a structure, the more energy required to penetrate the object to see its contents. If the pump is laying next to that dense item (i.e. something metal) then it is being unnecessarily exposed to that primary beam as well.
Hope you have a good trip without any major screening issues!
