Abstract

The invention discloses a scar repair material which is prepared by the following method: dissolving 0.5-5 parts by weight of water-soluble chitosan or chitosan the deacetylation degree of which is 75-97% into 10-100 parts by weight of water or an acetic acid aqueous solution the mass concentration of which is 1-5% while stirring; adding 1-3 parts by weight of polyoxyethylene Sorbitan lauric acid monoester which has emulsifying action and 5-10 parts by weight of humectant glycerol to obtain a transparent gelatinous solution; adding 20-90 parts by weight of polydimethylsiloxane into the gelatinous solution under homogeneity; and evenly mixing to obtain the scar repair material. The scar repair material disclosed in the invention can actively and passively moisturize skin, has the efficacy on actively resisting and inhibiting bacteria, has the action on quickening the healing of skin wound surface, has better repair and protection actions on tiny flaws and infection on the scar surface as being used on the scar surface, and can inhibit the secretion of collagen type I in cheloid skin so as to lower the ratio of collagen type I / collagen type III.

Description

technical field

[0001] The invention relates to a medical biological material, in particular to a scar repair material. Background technique

[0002] Most of the scar treatment products currently on the market are single-component silicone scar repair stickers or silicone gel scar repair creams made of polysiloxane. The principle of such products for scar repair is to seal the skin with silicone , Form a breathable and impermeable protective film, prevent the moisture in the scar from dissipating, and form hydration with the skin to repair the scar. However, this type of product has the following disadvantages: a, passively seals moisture, does not have the function of actively moisturizing scarred skin, and passively repairs scars by hydrating scarred skin, rather than actively promoting the change of scarred skin structure; b, silicon The gel seals the scar skin from external bacterial infection, but does not actively kill or inhibit the bacteria on the surface of the sca...
