Band-aids, 4x4s and compresses. If there is an Ollies store in your AO, stop by there and see if they have any Dr. Gameday brand bandages. If they do, buy them out. These are the best band aids I have ever seen. They will amaze you by how well they stay on.
4x4s are great for sopping blood so you can see what you are dealing with.
I have the Quik Clot and HemCon brand blood stoppers but I have never used them.
What I do use from time to time is called Kwik-Stop Styptic Power. It is in powder form, in a small plastic container roughly the size of a 35mm film can (remember those?) and you can buy it in pet stores. It might be a throw back to Benson Ragners' Ditch Medicine but I've used it for years. It works great and is inexpensive. I have never seen it cause any infection or side effects. It does sting a little.
The label says Do Not use on deep wounds, body cavities or burns.
Ingredients;Ferric subsulphate, aluminum chloride, diatomite, bentonite, copper sulphate,
ammonium chloride and benzocaine.
I handed it to a church member who cracked his head open on ice in the church parking lot one winter and started to explain to him what it is. He is a doctor. He abruptly interrupted me and said, 'I know exactly what it is', as he dumped a small pile in his palm and applied it to his wound. It washes out with warm water.
Only use a tourniquet for the squirts. You should get some training with them aslo. Risky business if you just strap it on like you see in the movies. A marker in your kit is better for the 'T' than blood because if he rubs his bloody hands on his forehead, he is no longer marked.
I've only needed to use them twice, both times were for table saw accidents. ( not mine, I still have all my digits)
