  • Patent number: 8668924
    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 5 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 10 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 15 blood out of the wound site.

  • Patent number: 7820872
    Abstract: A chitosan biomaterial is frozen in aqueous solution to form a frozen chitosan structure from which water is removed by a prescribed freeze-drying process to form a sponge-like chitosan structure having a thickness and a density. The sponge-like chitosan structure is compressed by application of heat and pressure to reduce the thickness and increase the density of the sponge-like chitosan structure to form a densified chitosan structure. The densified chitosan structure is further preconditioned by heating the densified chitosan structure according to prescribed conditions to form a wound dressing. The wound dressing possesses an adhesion strength and resistance to dissolution in high blood flow bleeding situations.
