Abstract: This invention is directed to advanced hemorrhage control wound dressings, and methods of using and producing same. The subject wound dressing is constructed from a non-mammalian material for control of severe bleeding. The wound dressing for controlling severe bleeding is formed of a biomaterial comprising chitosan, a hydrophilic polymer, a polyacrylic polymer or a combination thereof. The kind of severe, life-threatening bleeding contemplated by this invention is typically of the type not capable of being stanched when a conventional gauze wound dressing is applied with conventional pressure to the subject wound. The wound dressing being capable of substantially stanching the flow of the severe life-threatening bleeding from the wound by adhering to the wound site, to seal the wound, to accelerate blood clot formation at the wound site, to reinforce clot formation at the wound site and prevent bleed out from the wound site, and to substantially prohibit the flow of blood out of the wound site.

Abstract translation: 本发明涉及先进的出血控制伤口敷料，以及其使用和生产方法。 受试者伤口敷料由用于控制严重出血的非哺乳动物材料构成。 用于控制严重出血的伤口敷料由包含壳聚糖，亲水性聚合物，聚丙烯酸聚合物或其组合的生物材料形成。 本发明考虑的严重的威胁生命的出血通常是当将传统的纱布伤口敷料以常规压力施加到受试者伤口时不能被切断的类型。 伤口敷料能够通过粘附到伤口部位上来严重地伤害来自创伤的危及生命的出血的流动，以密封伤口，以加速伤口部位的血块形成，从而加强伤口部位的凝块形成 并且防止从伤口部位渗出，并且基本上禁止血液流出伤口部位。
