I carry what I am trained to use and has proved useful to me over the years:

It's *very* small

- Bandaids (good fabric ones, and waterproof duct-tapy type ones)
- Blister Pads of various sizes (small and biig ones)
- 1/4 oz nalgene of iodine
- 1/4 oz nalgene of polysporin
- 8 percocet tablets
- 4 4x4 gauze pads
- 2 2x2 gauze pads
- a half dozen butterfly bandages.
- a couple of knuckle bandaids
- a coupule of really large bandaids
- a full roll of very good 3m adhesive tape
- 4 doses of imodium AD
- 4 doese of benadryl

Everything else is provided by other stuff in my pack - I normally have a good supply of analgesics (ibuprophen, naproxen)and antihistamines as well as shirt that can become bandages, trekking poles and line that can become splints, duct tape, thread, needles, alcohol.. etc.

for stuff I'm *not* trained for I have a PLB.

I have an aquiaintaince I hike with who is a helicopter flight medic - and here that means he can intubate people and the whole 9 yards - he carries very little more than me.

You really can't do a lot more than that in the field without support. if you are concerned about more serious injuries, get a SPOT or PLB. (I have one).
