Problems solved by technology

[0002] In the past, the medical hemostatic material was to directly grind the dry product of the Chinese medicine Bletilla striata into powder without extracting it from the tuber of Bletilla striata, which contained more impurities and low content of effective substances, and was inconvenient to use. Up to now, there is still no sponge shaped hemostatic material

Abstract

The invention relates to a hemostasis material prepared from Bletilla and a preparation method of the hemostasis material. The hemostasis material in the prior art is used by grinding a traditional Chinese medicine arethusa dry product into powder and has the defects of more defect impurities, low effective substance content and poor hemostasis effect. In the hemostasis material disclosed by the invention, Bletilla polysaccharide is dissolved into water to prepare an aqueous solution of which the concentration is 1-3%, and the aqueous solution is prepared into the hemostasis material at low temperature under the condition of vacuum drying. The hemostasis material prepared from Bletilla has the advantages of simple technology, excellent hemostasis effect and convenience in use, and can be widely applied to medicine and the biomedical engineering.

Description

technical field [0001] The invention belongs to the field of medical materials, and in particular relates to a hemostatic material made of bletilla striata and a preparation method thereof. Background technique [0002] In the past, the medical hemostatic material was to directly grind the dry product of the Chinese medicine Bletilla striata into powder without extracting it from the tuber of Bletilla striata, which contained more impurities and low content of effective substances, and was inconvenient to use. Up to now, there is still no sponge shaped hemostatic material. Contents of the invention [0003] The present invention aims at the deficiencies in the above-mentioned prior art, and provides a preparation method of a spongy hemostatic material made of bletilla striata with uncomplicated process, convenient use and better effect. [0004] The object of the present invention can be achieved through the following measures: [0005] A hemostatic material made of ble...
