Can a Thermos Keep Trimix Cold for 17 Hours?

Hi guys,

I'll be traveling overseas from USA and I need a good cooler or thermos to keep trimix in at a very cold temperature for about 17 hours. I saw a thermos online that keeps ice cubes from melting for 24 hours. Would this be ideal to keep trimix in for a long flight?

Can you take it on with ice in it? I don’t fly enough to
Know what TSA allows anymore.

If so I would think freezing it and a little ice would be enough.

My doctor also said if mine sits out over night it’s not ruined and ok to use.

thermos and dry ice with a barrier between the trimix and the ice?
