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.
L'invention concerne un pansement amélioré permettant de contrôler les hémorragies, et des procédés d'utilisation et de production dudit pansement. Le pansement est constitué d'un matériau non mammifère et permet de contrôler les saignements sévères. Le pansement comporte un biomatériau comprenant du chitosane, un polymère hydrophile, un polymère polyacrylique ou une de leurs combinaisons. Le type de saignements sévères, dangereux pour la santé ne peut pas être régulé par un pansement en gaze classique, appliqué par une pression classique sur le sujet. L'invention concerne ledit pansement capable d'étancher l'écoulement du saignement de la blessure par adhésion au site de la blessure, ce qui permet de fermer la blessure, d'accélérer la coagulation du sang, de renforcer la formation d'une croûte sur le site de la blessure et d'empêcher le saignement hors du site de la blessure, et de prohiber sensiblement l'écoulement du sang hors du site de la blessure.
