The port won't explode. Neither will your 'foobs' if you end up with them in the end.
There's technical stuff you can look at, but if you are worried about the port, spare a thought for my friend who is going for his first flight with his new stoma.
If this stuff happened the airlines would-be all over it, they'd be making us pay three times the going rate to sit in sealed units in the cargo hold. If that's ever going to be a 'thing' and I'm going to be in a box with those likely to plaster the walls with body fluids, I'm a not going in with the stoma guy. ( Sorry, Gerry)
