Problems solved by technology

This kind of material hopes to use halloysite and chitosan to play the respective advantages of inorganic and organic materials to play a hemostatic and bactericidal effect, but as it says, halloysite nanotubes are inorganic materials, and the main components are silicon oxide, aluminum oxide and a small amount of other metals Oxides, such ingredients are difficult to be degraded and absorbed in the body, and cannot be hydrolyzed by lysozyme to exert a synergistic effect, so it is not suitable as a hemostatic powder for hemostasis in vivo

Abstract

The invention relates to an antibacterial and hemostatic microballoon containing berberine and preparation and application of the antibacterial and hemostatic microballoon. Hemostatic can be used in abody and can be rapidly degraded and absorbed. A compound antibacterial and hemostatic material with carboxymethyl chitosan, sodium alga acid, collagen and the berberine as raw materials is adopted,the characteristics of antibacteria and adhesivity of the berberine are used, and the material is enabled to obtain the antibacterial performance while the hemostatic effect is further enhanced. Meanwhile, under the environment of simulated body liquid after hemostasis, antibacterial and hemostatic effective componenets such as the carboxymethyl chitosan, the sodium alga acid, the collagen and theberberine are degraded, the characteristics of related materials such as polysaccharides and polypeptide capable of being hydrolyzed and micromolecule being easily metabolic and decomposed are used,and thus, the effect that the antibacterial and hemostatic material can be rapidly degraded and absorbed in the body is achieved.

Description

technical field [0001] The invention relates to an antibacterial and hemostatic microsphere containing berberine, a preparation method and related applications thereof. Background of the invention [0002] Trauma bleeding is one of the common factors that induce death. Effective hemostatic materials can quickly control bleeding, which is crucial for wound treatment and obtaining time for further rescue. How to stop bleeding quickly and effectively has always been the focus and difficulty in first aid and clinical treatment, but most hemostatic agents are only effective for small blood vessel bleeding, and the hemostatic effect for large-scale and deep-seated bleeding is not ideal. The hemostatic materials on the market are mainly divided into synthetic agents, physical agents, biological agents, absorbable agents and new hemostatic dressings. Synthetic preparations, such as cyanoacrylate adhesives, etc., can quickly form high-molecular polymers in the presence of water to q...
