band aids, obviously.
"wound wash"
+1 for super glue - preferably a bunch of teeny-tiny tubes. Cloth tape that you can apply to a wound and then saturate with super glue.
neosporin, neosporin, bacitracin, & neosporin.
"eye juice", large and small:

Really good tweezers. Seriously. Do not fuck around with less than the best: IMHO, tweezerman. (

Aloe vera gel for burns. Preferrably w/o alcohol, dye, or scent.
Instant ice packs - maybe. Most of them are too sucky to be worthwhile. Don't get cold enough or for very long. But if you don't have a ready source of ice, then definitely. Good for portable kit.
My wife (a former paramedic) really likes butterfly bandages and steri-strips. *shrug* I've gotten more use from cyanoacrylate (superglue)
If you are far from a hospital ... like the labs, say ... consider a surgical sewing kit. And some lidocaine. These are hard to buy, and require courage to use. You may have to buy "veterinary use only" or "training use only", which is better than bleeding to death.
Strong reading glasses - for when the person who will remove the shard of glass/wood/ceramic from your body turns out to be farsighted. Bright flashlight; preferably headlamp.
