A method is for making a hemostat device. The method includes preparing a homogenous solution of gelatin and chitosan by adding gelatin to water to form a gelatin solution, adding an acid to the gelatin solution to provide an acidified gelatin solution, and adding chitosan to the acidified gelatin solution to form the homogenous solution of gelatin and chitosan. The method also may include air drying the homogenous solution of gelatin and chitosan to provide an air dried scaffold, processing the air dried scaffold to provide a porous sponge, loading the porous sponge with a clotting agent by exposing the porous sponge to the clotting agent in an aqueous solution, and drying the loaded porous sponge. |
