Well, in the LUG Trek Player's Guide, they have the RRT Field Medic. He has training in first aid/combat trauma, medical sciences/surgery, and life sciences/biology to just name a few. And some toys like the hypo pouch (hypo-spray with six meds; anesthezine, cordrazine, hyronalin, melorazine, terazine, and tri-ox in it), forcefield generator (creates a shield around patient and medic so he can work on them), and the statis backboard (keeps patient in stasis up to 50 hours).
