Abstract

The invention relates to biological powder medical dressing and a preparation method thereof. The biological powder medical dressing is prepared by using main raw materials of chitosan, alginate, collagen peptide, epidermal growth factor (EGF), sodium carboxymethylcellulose (CMC) and pectin; the preparation method comprises the following steps: step 1, the chitosan, the collagen peptide and the epidermal growth factor are weighed in parts by weight, are fully stirred in a stirrer, and are mixed in solid powder to form a component A; step 2, the sodium carboxymethylcellulose, the pectin and the alginate are weighed in parts by weight at the normal temperature, and are mixed in solid powder; step 3, a mixed component B is slowly added in the component A for stirring; and step 4, biological powder is radiated for disinfecting to prepare the product. The method has the characteristics of reasonable technique process and high product yield; the biological powder medical dressing has simple preparation method and good stability, and is suitable for nursing acute wounds and chronic wounds in different periods.

Description

technical field [0001] The invention belongs to the technical field of medical dressings, and in particular relates to a biological powder dressing and a preparation method thereof. Background technique [0002] Biopowder medical dressings are all made of biology. It is a new type of nursing material with the advantages of biocompatibility, safety, anti-adhesion, antibacterial, hemostasis, and promotion of wound healing. Used in combination with moist wound dressings, it can block the wound from contact with the environment, prevent external infection, and promote wound healing. [0003] A biodegradable hemostatic powder (CN200610024198.2) was retrieved from domestic patents, which is characterized in that it is prepared from carboxymethyl chitosan, sodium alginate, calcium chloride, liquid paraffin and Tween 80; another The bactericidal hemostatic powder and its preparation method and application (CN201110006521.4) are composed of rush grass adsorbed with high-valent silv...
