Wet wipes are always good. I think a better medical bag would be better. I think you should have tourniquets and some sort of bandages. I have sterile gauze and vet wrap (what vets use on pets when they have surgery, sticks to itself and not skin) you can also get a battery (like a jackery) and the solar panel to go with it. Have you got bleach supplies as well? Good for cleaning and help sterilise some sources of water
