Abstract
Description
technical field
[0001] The invention relates to the technical field of medical materials, in particular to a quick hemostatic powder for trauma and a preparation method thereof. Background technique
[0002] Blood coagulation process is very complicated, and there are about 13 factors participating in the reaction, and calcium is one of them. There is a folk practice of burning eggshells to stop bleeding, the principle is the role of calcium. The hemostatic properties of chitosan have been reported in a large number of literatures. The hemostatic mechanism is that positively charged amino groups combine with negatively charged red blood cells and platelet surfaces to form mucoadhesive clots and activate the traditional coagulation pathway.
[0003] Chitosan is an alkaline polysaccharide obtained by deacetylation of chitin. Due to the amino group in chitosan molecule, it has many excellent properties such as biocompatibility, biodegradability, hemostasis, and inhibition. Ba...
