Novel skin regeneration material and preparation method thereof

Abstract

The invention relates to a novel skin regeneration material and a preparation method thereof, and belongs to the biomedical material processing technical field. The skin regeneration material is divided into a drug agent layer and a gel layer, wherein the gel layer is composed of alginate, chitosan, a grease microcapsule powder, nano silver and deionized water. The preparation method comprises the steps of adopting a solution spinning method to obtain an alginate fiber, then pressing with a cladding material and a drug agent to obtain the novel skin regeneration material. The skin regeneration material is capable of protecting wound surfaces, relieving pain, stopping bleeding, diminishing inflammation, promoting growth of newly-born granulation tissues and epithelial cells, accelerating wound surface healing and the like, has the advantages of excellent antibacterial performance, good biological safety and the like, and is wide in application range and suitable for various wound surfaces with a large amount of exudates, various bleeding wounds and various chronic, infected and difficult-to-heal wound surfaces.

Description

technical field [0001] The invention relates to a novel skin regeneration material and a preparation method thereof, belonging to the technical field of medical material processing. Background technique [0002] Dressings are wound-wrapping supplies, medical materials used to cover sores, wounds or other damage. With the in-depth study of the pathophysiology of the wound healing process, people's understanding of the wound healing process has become more and more profound, which has led to the continuous improvement and development of medical wound dressings. High-tech medical dressings are gaining more and more attention in the world's medical and health fields. Traditional dressings such as medical absorbent cotton gauze and cotton pads are increasingly being used by new types of dressings because they cannot keep the wound moist, delay wound healing, have poor permeability barriers, and have poor hemostatic effects. Medical dressings instead. With the advancement of Chi...

Both of the above two patents use nano-silver as an antibacterial agent. Generally, in order to have a significant antibacterial effect, the amount of nano-silver used is relatively large, which leads to an increase in costs.

CN201310520955.5 discloses a functional dressing and its preparation method and application. It is composed of bioactive glass, alginate, chitosan and other components. The bioactive glass needs to go through steps such as high-temperature calcination and grinding, and the preparation process is complicated. And the dressing only has antibacterial effect of alginate and chitosan, and the antibacterial effect is not obvious, but if other antibacterial ingredients such as antibiotics and preservatives are used, problems such as drug resistance and secondary infection will occur
