When an emergency medical technician is treating a victim, time spent searching for the right gear could be the difference between life and death. Celox trauma gauze is the only two-in-one gauze that can both seal gashes and cool burns. Woven from chitosan fibers, a blood-clotting agent derived from shrimp shells, it absorbs 16 times its weight in blood. For burn victims, medics can wrap the wound and then soak it with water to turn the bandage into a gel that evaporates to cool burns by 10ºF for 20 hours. Military medics looking to lighten their load have already placed orders for the multitasking gauze.
