How about getting a Leatherman Micra? It has a blade wich, when very sharpened,
can replace the scalpel-and razor blades. It also has a pair of tweezers and good scissors.

Also I would replace the small bottle of Betadine with some Povidone-Iodine swabs if available.

I don't think you'll need a thermometer in your kit. If you really want to, replace it with a 'flexible-thermometer' wich take up far less space.

Rewind de medical tape on a small object, for example a paper-clip. You'll probably won't need a whole roll.

Use only 1 steri-strip pack. Add some small Band-Aid butterfly closures.

Do you really have to carry that much saline ampules? I carry 2 10ml ampules in my FAK. Seems like you carry more.

That's about it. Good luck!
