I have to admit, as a retired medic, I find this thread very interesting. It has been fun reading the different ideas that you guys are suggesting. All would work and many are IMHO spot on.
If you factor in that, many times, today's medic is expected to be a soldier first and a medic second, the Adamas looks like it would be perfect. Except for the cost. The HK Axis seems to be the perfect compromise, being in the right price range and offering many features of the Adamas. Both are fine products that will serve your friend well. As for the Triage, I have drooled on one but have never used it in the field so I can't really say much except that I would love to own one.
The Leatherman RAPTOR did not exist when I was in. It would have been great to have but, for me, not a must have item. Here is the reason why. If other people use your gear, many times you never see it again. A lot of the people you come in contact with have sticky fingers and a cool item like the RAPTOR would be one of the first things to walk away. Secondly, your stuff gets trashed if you loan it out. Also, So, I would have to have to field two RAPTOR tools. That is a cost that I am not willing fork out.
So, what did I carry? CRKT M16-02 or a CRKT Prowler. The Prowler was my favorite of the two. Both were easy to replace. If I had to do it again I would carry an Adamas and a Gerber or Leatherman multi-tool some sort. Maybe instead of the MT I would carry a SAK. It just depends upon the mission.
Today's medic has better kit and more of it than ever before, so weight may be an issue. I know it would be for me. It seemed that I always had more crap to carry than the troops I worked with.
