Abstract

The invention discloses a chitosan iodine biomaterial capable of killing bacteria and pathogenic microorganisms. The chitosan iodine biomaterial mainly comprises, by weight, 0.05-1% of iodine, 0.1-0.5% of potassium iodine, 0.15-0.4% of potassium iodate, 1-4% of glycerol, 0.1-0.2% of boric acid, 5-15% of polyvinylpyrrolidone, 0.1-1.0% of water-soluble chitosan, 0.1-1.0% of sodium alginate, 0.05-1.0% of calcium bicarbonate, 0.1-0.4% of tea polyphenols, 5.0-8.0% of buffer phosphate, and the balance of injection water or purified water. The chitosan iodine biomaterial is nontoxic, nonirritating ornon-allergic to human, has good biodegradability and biocompatibility, has good sterilizing and wound-healing functions, and can prevent implantation metastasis due to scattering of tumor cells of human cavity internal membranes during tumor surgery.

Description

technical field [0001] The invention relates to a medical sterilization, antibacterial, anti-adhesion, biological material and skin and mucous membrane external disinfection and surgical field skin and mucous membrane biological material used in the perioperative period, in particular to a chitosan iodine biological material and a preparation method thereof. Background technique [0002] At present, the traditional preparation of iodine-containing preparations is mainly polyvinyl ether and polyvinylpyrrolidone-embedded iodine preparations. The defect of this iodine preparation is that high-energy iodine can be stored for a long time, but the available iodine below 5000PPm iodine solution is easy to volatilize. It is very effective to be prepared into tincture of iodine, but it is very irritating to the skin and mucous membranes. Low-concentration chitosan iodine microsphere sol solution preparation is still a blank. [0003] In surgical infectious operations such as intesti...
