A hemostatic device for promoting blood coagulation comprises a substrate (eg, gauze, textile, sponge, sponge matrix, one or more fibers, etc.), a hemostatic material disposed thereon, such as kaolin clay, and substantially retains the hemostatic material. a binder material such as cross-linked calcium alginate having a high molar percentage of gluronate monomer for binding. When the device is used to treat a bleeding wound, at least a portion of the clay material is in contact with blood to promote clotting. Also, when exposed to blood, the binder has a low solubility and keeps most of the clay material on the gauze. A bandage that can be applied to a bleeding wound to promote blood clotting includes a flexible substrate and a gauze substrate mounted thereon. |
