Problems solved by technology

[0004] The above inventions and their dressing products mainly focus on protecting the wound environment, promoting wound healing, and preventing wound infection. Although they have played a good role in wound treatment, they do not involve the prevention and reduction of scar formation. The formation of scars not only affects the appearance, but also causes symptoms such as poor perspiration and severe itching, causing great pain to patients

Abstract

The invention discloses biological dressing for preventing scar formation and a preparation method thereof. The biological dressing for preventing scar formation comprises a packing material, a base material and a dressing medicament. The dressing medicament is composed of the following raw materials: sodium hyaluronate, composite bioactive peptide, EGF, KGF, FGF, glycerin, hydroxyethyl cellulose,chitosan, phenoxyethanol, a Hamamelis Virginiana extract, a scutellaria baicalensis root extract, a raspberry extract, a garden burnet extract, an onion extract and water. Meanwhile, the invention also discloses a preparation method of the biological dressing for preventing scar formation. As the biological dressing for preventing scar formation contains hyaluronic acid, EGF, KGF, small molecularbioactive peptide and various plant extracts and other bioactive components, the biological dressing has effects of promoting healing and preventing and minimizing scar formation and can be used fortreatment and nursing of various body surface wounds and problem skin.

Description

technical field [0001] The invention relates to a biological dressing for preventing scar formation and a preparation method thereof. Background technique [0002] The repair of human skin damage is a complex physiological process. The speed of wound healing and the formation and proliferation of scars after healing have always been difficult problems for people. For this reason, people are trying to find ideal dressings, including good biocompatibility, control and absorption of wound exudate, preventing bacterial invasion and inhibiting bacterial growth and reproduction, protecting new tissues, accelerating wound healing, preventing and reducing scars , hemostatic analgesia, good mechanical properties, etc. But also do not have a kind of dressing can reach and satisfy above-mentioned requirement so far. [0003] With the development of molecular biology, the research on the application of biomaterials in medical dressings is increasing, and a lot of results have been obt...
