Abstract
This invention relates to a hemostatic agent used in surgical operations, which can be produced in two ways: one blending collagen/gelatin with protamine, the other blending collagen/gelatin with protamine and a bi-functional cross-linking agent so as to make said collagen/gelatin have a covalent bond with said protamine. The produced hemostatic agent can stop bleeding within far less time than a conventional hemostatic agent made out of pure collagen.
