I'm an RN by trade and in a best case scenario the following are what I would like to have on hand at all times. It comes up to around 6lbs of gear so quite a hearty load for medical supplies, but you can stabilize most common injuries with these. If you're looking for reading material on the subject I'd recommend "where there is no doctor/dentist" and "the boy scout manual on first aid and wilderness medicine" both are written with the assumption the reader has zero medical knowledge and as such are great for the aspiring barbersurgeon.
As far as treating lacerations goes, which is what I'm assuming you're asking about regarding "cuts". If you have absolutely nothing to work with: make a fire, burn wood until it's white ash, pack the wound with ashes until you can get proper treatment, ashes are sterile and will help absorb the blood and promote clotting. If you have sutures you can attempt to stitch it yourself, but that shit isn't like the movies and if you have a wound that needs stitching it's gonna hurt like a motherfucker. If you have absolutely nothing for pain sit on your arm until it goes numb or tourniquet it. It'll dull the pain enough to get the needle in, you'll need to stich at least a quarter inch down to get the flesh to bind.
If you break your leg, you're fucked more or less and if the pain doesn't knock you out the shock eventually will and for all you know you could busted all kinds of blood vessels and are bleeding out under your skin so scream and holler and try and get some help, call the cops on yourself if you have too.
Also take care of your feet, no feet = no travel. Stop and change your socks every four hours minimum.
If this info was any help to you at all please share it with other to help ease their burdens as well. We gotta stick together out here.
Be safe have fun and may everything you attempt instantly succeed.
