The invention discloses a compound polysaccharide anti-hemorrhagic thin film and a preparation method thereof.The thin film is prepared from, by mass, 10-20 parts of chitosan, 2-8 parts of glucose, 3-6 parts of methylcellulose, 1-5 parts of gelatin, 4-7 parts of pectin, 4-7 parts of sodium trimetaphosphate, 8-20 parts of polyhydric alcohols, 5-8 parts of agar, 2-8 parts of sorbic acid, 5-10 parts of sodium alginate, 3-6 parts of panax notoginseng, 1-3 parts of sodium fumarate and 2-5 parts of sanguisorba officinalis.A polysaccharide serves as a matrix, proper anti-hemorrhagic components and auxiliaries are added, and the film-shaped anti-hemorrhagic material is prepared.Compared with conventional powder or spray, the film-shaped anti-hemorrhagic material can stop bleeding in two aspects synchronously.In the early time of bleeding, the film body is similar to tourniquet and can quickly stop bleeding, the anti-hemorrhagic components in the film synchronously stop bleeding at the same time, and the thin film has dual anti-hemorrhagic functions, greatly shortens bleeding time and is obvious in anti-hemorrhagic effect and convenient to use.
