Problems solved by technology

Chitosan-based hemostatic materials are already on the market, but it usually takes a few minutes for a single-component chitosan hemostatic product to promote the formation of a blood clot, so the hemostatic effect is not ideal in the case of large bleeding, and it is difficult to meet the strategic needs. Trauma hemostasis and clinical rapid hemostasis requirements, and the preparation process of sponges, membranes, bandages and other product forms is relatively complicated, the production cycle is long, and the production cost is high

Abstract

The invention relates to the technical field of medical materials and particularly relates to rapid hemostatic powder for an injury and a preparation method of the rapid hemostatic powder. The rapid hemostatic powder for the injury comprises the following raw materials in parts by weight: 40-56 parts of chitosan quaternary ammonium salt, 28-36 parts of puffball extracts, 8-12 parts of sodium alginate, 1-5 parts of ramie root extracts, 1-5 parts of cirsium setosum extracts, 1-5 parts of madder extracts and 0.5-1.5 parts of carbonized hair extracts. The rapid hemostatic powder for the injury can take a hemostasis effect through various approaches and remarkably shorten the blood coagulation time, also has the effects of inhibiting and resisting bacteria, relieving pain and promoting wound healing and can be widely applied to rapid hemostasis, emergency treatment and treatment of skin scratch, injury and haemorrhoids and relief of scar formation.

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...
