Problems solved by technology

[0005] 1) Limitation of application direction: the existing scar stickers cannot be applied to non-closed wounds;
[0006] 2) The product function is single: the existing scar plasters are generally composed of a backing layer, a gel layer and a release layer; but they can only provide a moist healing environment and keep the moisture of the closed wound surface, and cannot promote wound healing and functional recovery;
[0008] 4) Repeated application affects product effect: Although existing products can be used repeatedly, bacterial contamination is prone to occur during repeated use, and the curative effect cannot be guaranteed;
[0009] 5) Difficulty in combining drugs: it is difficult to combine drugs that inhibit scar formation, promote wound healing, or inhibit bacteria in wounds during the preparation process of conventional silicone gel scar plasters;
[0010] 6) The healing wound surface is prone to itching when used

Abstract

The invention discloses a functional gel layer, a scar patch and a preparation method of the scar patch, and relates to the technical field of medical supplies. The functional gel layer comprises the following components in parts by weight: 2-30 parts of a protein repairing agent, 0.5-10 parts of sodium hyaluronate and the balance of purified water, and the sum of the parts by weight of the components is 100; the protein repairing agent is selected from at least one of collagen and mussel mucin. The scar patch disclosed by the invention can be directly applied to non-closed wounds, and can be used for inhibiting scar formation, reducing the itching degree, promoting wound healing and accelerating functional recovery of skin tissues.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a functional gel layer, a scar patch and a preparation method thereof. Background technique [0002] Various traumas, burns, operations, infections, and injections can cause the occurrence of skin pathological scars. The formation of scars is the repair process of tissue damage, and scars are the traces formed after the skin tissue is damaged and healed. When the skin is damaged as deep as the reticular layer of the dermis, any wound healing will be accompanied by scar formation in varying degrees. The matrix of the scar is connective tissue, and the main component is collagen fibers. According to different surface morphology, histological and clinical features, common scars can be divided into flat scars, hypertrophic scars, atrophic scars, depressed scars and contracture scars. Scars are formed by the growth of fibrous tissue and are a manifestation of skin self-repai...
