Giant sponge-filled syringe for plugging gunshot wounds

Cory Doctorow 2:00 pm Wed Feb 5, 2014

XStat's Rapid Hemostasis System is a giant syringe filled with pellet-shaped sterile sponges doped with hemostatic agents for squiring directly into ~~shotgun~~ gunshot wounds. Within 15 seconds, the sponges absorb blood and expand, staunching the wound.

The sponges themselves are standard medical sponges that were coated with a hemostatic agent and then compressed. Once they come in contact with liquid, they rapidly expand and fill a substantially larger volume than their compressed state. Besides helping block blood flow, the sponges also provide a surface on which blood can begin clotting. Because the sponges have to be eventually removed, each has a tiny radiopaque marker so that any remaining in the body can be spotted on X-ray
