The invention provides an antibacterial hydrogel suitable for diabetic foot ulcers and a preparation method thereof, belonging to the technical field of medical hydrogel preparation. The preparation method is as follows: (1) adding acrylic acid, a cross-linking agent and an initiator solution to the sodium alginate solution to modify the sodium alginate; (2) adding a medicinal active component D and an antibacterial component E, and adding CaCl 2 solution to prepare a crude gel product; (3) after washing the crude gel, blot dry with filter paper to obtain the antibacterial hydrogel. By improving the sodium alginate, the hydrogel prepared by the invention can greatly improve the speed of absorbing the exudate from the wound surface, so that the wound surface can be treated in time, and Chinese medicine ingredients are added, which penetrates into the wound surface through slow release and is absorbed by the human body. Playing the role of topical medicine, the addition of Liquor Saponin R can improve the blood supply of the ulcer, thereby synergistically improving the healing speed of diabetic foot ulcer. |
