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, in particular to medical quick biological rhinal styptic powder and a preparation method thereof. The medical quick biological rhinal styptic powder is composed of, by weight, 65-85 parts of lasiosphaera seu calvatia extracts, 10-14 parts of sodium carboxymethylcellulose, 1-5 parts of cirsium japonicum extracts, 1-5 parts of lalang grass rhizome extracts, 1-5 parts of flos sophorae extracts, 1-5 parts of Indian mockstrawberry extracts and 0.5-1.5 parts of cacumen platycladi extracts. The medical quick biological rhinal styptic powder is capable of realizing stypticity by various means and evidently shortening blood clotting time, further has functions of bacteriostasis, antibiosis, analgesia and acceleration of wound healing and is widely applicable to postoperation quick hemostasis, pain relief and wound repair for nasal cavities, oral cavities and throats.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a medical biological nasal cavity rapid hemostatic powder 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...
