Patent ID: 8303981

Claim:
A method for preparing a hemostatic composition, the method comprising: preparing an aqueous solution containing thrombin; drawing the aqueous solution into a first syringe; connecting the first syringe with a fitting; connecting a second syringe with the fitting, wherein the second syringe contains an amount of resorbable fragmented cross linked gelatin gel having an equilibrium swell value within a range from about 400% to about 1300%; injecting the aqueous thrombin solution from the first syringe into the gelatin gel contained in the second syringe; passing the combined thrombin solution and gelatin gel back and forth between the first and second syringes, thereby mixing the thrombin solution and gelatin gel so as to form the hemostatic composition; and delivering the hemostatic composition to a bleeding site or bleeding tissue surface of a patient, or to an abraded or damaged tissue surface of a patient, wherein the formula 100 ⁢ % × equilibrium ⁢ ⁢ wet ⁢ ⁢ weight - dry ⁢ ⁢ weight dry ⁢ ⁢ weight characterizes the equilibrium swell value of the gelatin gel.
