Patents by Inventor Xiaoqiang SHANG

Xiaoqiang SHANG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11951228
    Abstract: 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.

  • Patent number: 11154512
    Abstract: A hemostatic compound is provided. The hemostatic compound comprises molecular sieves and a fiber. The molecular sieves are independently dispersed on a fiber surface of the fiber without agglomeration and directly contact the fiber surface. A first surface of the molecular sieve contacted with the fiber is defined as an inner surface, and a second surface of the molecular sieve uncontacted with the fiber is defined as an outer surface. The molecular sieve forms a growth-matched coupling with the fiber on the inner surface, and the growth-matched coupling refers to that a plurality of molecular sieve microparticles grow to match the fiber surface to form a tightly-coupled coupling interface that matches the fiber surface.
