Known Bandage / Triangular Bandage

There are always injuries coming together with wars. Nowadays in the world, places with conflicts are often lack of public health services. Civilians who probably haven’t been trained should save themselves sometimes when there are no medical workers in emergency.
“Known bandage” is a triangular bandage which has clearly instructions on it. By referring to the icons printed on the bandage, rescuers can easily follow the instructions to do a perfect bind. Under an emergency condition such as a war, people can rescue each other with “Known bandage” if medical help is very limited.
