Hemostatic compositions and methods of making thereof

The present invention is directed to hemostatic compositions comprising at least partially integrated agglomerated ORC fibers, fibrinogen, and thrombin and methods of forming a powdered hemostatic composition, comprising the steps of: forming a suspension of a mixture comprising particles of fibrinogen, thrombin, ORC fibers in a non-aqueous low boiling solvent, agitating and shearing said suspension in a high shear mixing reactor, adding water to allow particles to agglomerate, allowing the non-aqueous solvent to evaporate, drying and sieving the composition; and thus forming the powdered hemostatic composition.

Blood Coagulation-Promoting Silk Fibroin-Polypeptide Electrospun Membrane and Preparation Method Thereof
20220088266 · 2022-03-24 ·

The present invention discloses a blood coagulation-promoting silk fibroin-polypeptide electrospun membrane and a preparation method thereof. The electrospun membrane is made by using silkworm silk fibroin as a carrier and adding the polypeptide GPRPPSEHLQIT. It is mainly used for promoting blood coagulation, and is a blood coagulation material that can targetedly bind to human fibrinogen. The preparation method includes the steps of dissolving, filtering, dialyzing, concentrating and freeze-drying silkworm cocoons after degumming to obtain silk fibroin freeze-dried powder. The polypeptide used in the present invention is a polypeptide obtained by self-screening. Compared with other polypeptides, it can specifically targetedly bind to human fibrinogen.

Provided is a hemostatic composition comprising trypsin and zeolite, wherein pore channels of the zeolite are micropores, the zeolite contains divalent metal cations, and the mass ratio of the trypsin to the zeolite is 1:200-4:10. In the present invention, the trypsin specifically binds to the zeolite, allowing the trypsin to maintain a certain conformation on the surface of the zeolite and to obtain a higher procoagulant activity, thereby obtaining a hemostatic composition with an excellent blood coagulation effect. The hemostatic composition of the present invention has the advantages of a simple preparation method, low cost and convenient use, and can be widely used in hemostasis during trauma and operations, especially in emergent hemostasis in hemophilia patients.
