Material Made From Crustaceans Could Combat Battlefield Blood Loss

MTorrice writes: A foam composed of a polymer derived from crustacean shells may prevent more soldiers from falling victim to the most prolific killer on the battlefield: blood loss. Pressure is one of the best tools that medics have to fight bleeding, but they can’t use it on severe wounds near organs. Here, compression could do more harm than good. First responders have no way to effectively dam blood flows from these non-compressible injuries, which account for the majority of hemorrhagic deaths. The new foam could help stop bleeding in these types of injuries. It relies on chitosan, a biopolymer that comes from processed crustacean shells. By modifying the chitosan, the developers gave the material the ability to anchor blood cells into gel-like networks, essentially forming blood clots. The researchers dispersed the modified chitosan in water to create a fluid they could spray directly onto noncompressible wounds. Read more of this story at Slashdot.
