Most first aid kits aren't that useful. And once you DO use them, the next time you need something, it's not there. STAT Medical Supply of Salt Lake City had an idea to produce a truly useful deluxe first aid kit. The CD explains each item in the kit with text, pictures, and video clips, and even lets you construct a shopping list of replacement items for your kit. The CD also includes an injury-management section.
Video clips show how it's done.
Mad Scientist doesn't sell first aid kits.
