This topic is certainly something to think about. I carried a tourniquet (piece of solid #12 copper wire) on my scuba diving tank and on my dive partner's tank.
What about antibiotic spray for large road rash?

As an electrician I always have a roll of electrical tape. It can be used to fix stuff on the bike as well for stuff on the human body. You should buy the high quality Scotch 33+ or at least the 1700.
Keep in mind that tape stops sticking after a few years so it needs to be cycled.
