    An injectable, wound-filling foam could help to stabilize hard-to-tourniquet wounds for transport to a medical station.
    The system will be designed to staunch bleeding at the areas where the head or a limb is attached to the torso--areas notoriously difficult to tourniquet--by injecting two liquids directly and deeply into the wound. The two liquids, polyol and a diisocyanatein, will be held in separate sections within the syringe until injection into the body, whereupon they will mix to form a foam that will expand and then harden within the wound.
