Abstract

A hemostatic material and a method of treating a bleeding wound of a human or an animal include a hemostatic powder for application to the wound. The hemostatic powder comprises a first part consisting of a native chitosan base and a second part consisting of a chitosan salt, where the first and the second parts form the main component of the hemostatic powder, or at least 50% of a total weight of the hemostatic powder, and the second part forms a layer that at least partially coats the first part. The hemostatic powder may be provided in a hemostatic spray formulation that comprises a mixture of the hemostatic powder dispersed in a liquefied gas for release from a cannister onto the wound. A treatment method involves applying the hemostatic spray formulation directly to the wound. Other embodiments are also disclosed.
