Abstract

The invention relates to novel antibacterial restorative functional dressing and a preparation method thereof. The novel antibacterial restorative functional dressing is formed by crosslinking and compounding chitosan and collagen on a bacterial cellulose membrane through a cross-linking agent, wherein a mass ratio of the chitosan to the bacterial cellulose membrane is (0.001-5) to 100; a mass ratio of collagen to the bacterial cellulose membrane is (0.5-20) to 100; a mass ratio of the chitosan to the collagen is (0.001-5) to (20-0.5); and the collagen is a mixture of collagen with small molecular weight and collagen with large molecular weight according to a ratio of 1 to 1. The antibacterial restorative functional dressing has very good biocompatibility, cellular affinity and mechanical property, has excellent water-permeable, gas-permeable or drainage and moisture absorption effect, has the effects of realizing antisepsis and anti-inflammation, reducing wound infection and quickly relieving pain of the wound, and has the effects of relieving chromatosis and promoting the wound to heal during a wound healing period. Meanwhile, the dressing can naturally drop along with epithelial regeneration, so that the treatment time and cost is reduced, and the wound infection probability is reduced.

Description

technical field

[0001] The invention relates to the technical field of biomedical materials, in particular to an antibacterial repair functional dressing and a preparation method thereof. Background technique

[0002] With the rapid development of modern science and technology, the research on medical dressings has achieved rapid development. Various new types of medical dressings continue to appear, and their performance is getting better and better. However, medical dressings are a type of clinical medical supplies that temporarily cover wounds such as burns, ulcers, and wounds. It has the function of promoting the recovery of wound skin function. my country's medical dressing industry is mainly based on low-end and mid-range products. Most enterprises are small in scale, have little investment in research and development, and have weak product technology capabilities. As a result, they lack competitiveness in high-end products, and the market competition for low-end and...
