Abstract

The invention relates to a medical collagen dressing, and a preparation method and applications thereof. The dressing is made of nonwoven cloth and collagen liquid. The collagen liquid comprises 0.1 to 20% of fish skin collagen, 0.1 to 10% of chitosan, 0.1 to 10% of hyaluronic acid, and 0.001 to 0.5% of epidermal growth factor. The provided collagen dressing can be used to treat acne with light and moderate inflammation, repair scars and hyper-pigmentation after photo-rejuvenation, improve the microenvironment of epidermis cells, promote the metabolism of skin tissues, whiten the skin, eliminate skin wrinkles, increase the elasticity and water of skin, and delay aging. The fish skin collagen is originated from fish skin and is very safe; compared with animal collagen, the risk of viral transmission and raw material cost are both reduced; chitosan nonwoven cloth is used to achieve an antiseptic and antibacterial effect without using any antiseptic; and the prepared collagen dressing has the advantages of wide application range, simple preparation technology, high stability of dry products, and convenience in preservation and transportation.

Description

technical field [0001] The invention relates to a medical collagen dressing and its preparation method and application, belonging to the field of medical or beauty products. Background technique [0002] Collagen is an excellent natural polymer substance and the main component of the extracellular matrix. It comes from a wide range of sources and is mainly distributed in skin, bones, tendons, blood vessels and other parts. It has good biocompatibility and biodegradability . Collagen has a unique triple helix structure, which not only supports and protects tissues and organs, but also participates in a series of biological processes, including cell adhesion, migration and differentiation, and tissue regeneration. In addition, collagen also It has many functions such as hemostasis, promoting tissue growth, repairing damage, moisturizing and locking water, and reducing pigmentation. Therefore, as a natural biomass resource, the importance and economic status of collagen in fo...
