hemostatic and wound devices and dressings and processes for producing hemostatic device and for treating wounds

摘要

“Hemostatic and wound devices and dressings and processes for producing hemostatic devices and for treating wounds” summary hemostatic devices for promoting blood clotting may include a substrate (e.g., gauze, tissue, sponge, sponge matrix, one or more fibers etc.), a hemostatic material disposed thereon such as kaolin clay and a binder material such as crosslinked calcium alginate with a molar percentage of high guluronate monomer disposed on the substrate to substantially retain the hemostatic material. When the device is used to treat a bleeding wound, at least some of the clay material contacts the blood to accelerate clotting. In addition, when exposed to blood, the binder has low solubility and retains most of the clay material on the gauze. a bandage that may be applied to a bleeding wound to promote blood clotting includes a flexible substrate and a gauze substrate mounted thereon. 1/1
