Abstract

The invention discloses a chitosan-based hemostatic material and a preparation method thereof. The chitosan-based hemostatic material is prepared from, by mass, 20-40 parts of chitosan, 8-12 parts of corn starch, 1-5 parts of whey protein, 2-5 parts of wheat starch, 1-5 parts of glucose, 2-5 parts of sodium alginate, 2-10 parts of pectin, 1-4 parts of lecithin, 1-4 parts of citric acid, 1-3 parts of sodium fumarate, 1-4 parts of sodium chloride and 8-15 parts of polyhydric alcohol, wherein polyhydric alcohol adopts ethanol or glycerol, and preferably, 2-6 parts of vitamin C and 1-3 parts of vitamin E are included. The chitosan-based hemostatic material has the advantages that the excellent anti-bacterial, hemostatic and analgesic effects are achieved, defective tissue repairing can be facilitated, the anti-adhesive effect is good, the biocompatibility is achieved, the safety are good, the antigenicity does not exist, use is safe, the preparation method is simple, and use is convenient.

Description

technical field [0001] The invention belongs to the field of medical materials, and in particular relates to a chitosan-based hemostatic material and a preparation method thereof. Background technique [0002] Excessive blood loss caused by traffic accidents, natural disasters, surgical operations, etc. may lead to death, so the development of a fast and effective hemostatic material has become a topic of great concern to experts and scholars in related fields. At the same time, with the improvement of people's material living conditions, people pay more attention to their own health, so higher requirements are put forward for the applicability and functionality of medical materials. As an excellent medical hemostatic repair tissue engineering scaffold material, not only the usual The hemostatic time is short, the hemostatic effect is good, the wound infection cannot be increased, and the secondary trauma should not occur. The implanted material in the body should also have ...
