Problems solved by technology

[0005] At present, most of the products on the market are made of hyaluronic acid with a single molecular weight, so it cannot take into account the multiple effects of hyaluronic acid with different relative molecular weights on wound healing, and cannot exert the best effect of hyaluronic acid

Abstract

The invention discloses medical dressing of a hyaluronic acid and a preparation method of the medical dressing. The medical dressing is prepared from the following components in percentage by mass: 0.1-5% of hyaluronic acid, 5-20% of Vaseline, 0.1-1% of carbomer, 0.1-0.5% of propylene glycol, 0.01-1% of glycerinum, 0.05-1% of allantoin, 0.05-1% of D-panthenol and 0.01-15 of hydroquinone. The dressing is compounded by the hyaluronic acids with different molecular weights; hydroquinone is added to the dressing; the hyaluronic acids and the hydroquinone have a synergistic effect through combined utilization, and are capable of penetrating into the inside of the skin, promoting wound repairing, playing an antiinflammation role, promoting metabolism of human protein, fat and carbohydrate and stimulating growth of epithelial cells; the medical dressing is especially suitable for wound repairing of skin and mucosa.

Description

technical field [0001] The invention belongs to the technical field of medical technology, and in particular relates to a hyaluronic acid medical dressing and a preparation method thereof. Background technique [0002] Hyaluronic acid (HA) is a natural linear polysaccharide, which is a straight-chain homopolysaccharide formed by repeatedly connecting the disaccharide units of glucuronic acid and N-acetylglucosamine, and is an anionic polymer. HA is one of the main components of skin tissue. All tissues and body fluids in the body contain hyaluronic acid. Sufficient HA in the skin can prevent skin aging, dehydration, and inhibit fibrosis. HA is mainly used in the formation of fibrosis in the body It is synthesized in the plasma membrane of cells or other cells and epidermal keratinocytes, and is one of the main components of intercellular matrix and extracellular matrix. [0003] Wound healing of human skin and mucous membranes is a process involving the reconstruction and r...
