There are tons of differing ideas for a "ditch kit"/ PSK/ emergency survival kit/ etc etc. I for one carry something a bit bigger, and it includes a pretty complete first aid kit with a torniquet. It does not contain super glue, because the outdoor medical professionals all agree that it is one of the worst ways to control a laceration.Cleaning and irigating (using those iodine pills) is best, then covering with a clean dressing. Duct tape is better than a dirt filled wound, but it is hell to get off, and can tear the wound worse. The snake bit kits have been scientifically tested, and don't work. Getting to a hospital is the best snake bit treatment.
I would also suggest that it is largely pointless, IMHO, to have water treatment pills without a water storage device. A 1 qt freezer bag is better than nothing. Those big rubber bands in the photo are useful in place of cordage, but I like some 550 in my kit. I also like a whistle, and a good emergency blanket.
