Not to cause wounds, but to treat them. Gunshot wounds can get deep and affect arteries. When this happens, it is important to stop the bleeding as quickly as possible. The current treatment is to shove gauze deep inside the wound.The FDA has approved a new technology that uses a syringe filled with sponges to stop the flow of blood. These sponges absorb blood and expand. They are coated with a chemical to trigger clotting. They also have an “X” imprinted on them that shows up in X-Rays so it’s easy to find them and get them all out. They supposedly can stop arterial bleeding in 15 seconds. Very useful for military medics. I’m sure this would have been useful in M*A*S*H at the aid stations.
