Problems solved by technology

If the collagen in the collagen dressing is animal-derived collagen, many influencing factors must be considered, such as: the denaturation temperature of animal-derived collagen is 42°C, the preservation of collagen dressings must be strictly controlled below 40°C, and avoid High temperature, which brings some difficulties to transportation and storage, and the product may face deterioration if it is not careful; there is another biggest factor for animal-derived collagen, which is instability. After the product is placed for a period of time, it will appear Adverse reactions such as peculiar smell will bring rejection to patients. Animal-derived collagen has a fatal shortcoming, that is, there are hidden dangers of viruses, such as avian influenza virus, foot-and-mouth disease, mad cow disease virus, mycoplasma and chlamydia, etc. Although collagen dressings can Relieves various symptoms, but there are certain risks

Abstract

The invention discloses a collagen dressing, which is composed of a collagen complex liquid and nonwoven cloth impregnated in collagen. The collagen complex liquid is composed of following componentsin parts by weight: 1 to 10 parts of C3 polyol, 0.01 to 0.5 part of recombinant human-derived collagen, 0.1 to 0.5 part of lactobionic acid, 0.05 to 0.2 part of gluconolactone, 0.2 to 0.5 part of antiseptic, and the balance being injection water, wherein the total parts by weight is 100. The invention also provides a preparation method of the collagen dressing. The collagen dressing is little irritant to the skin, is mild, has a moisturizing function, and can effectively promote the metabolism of cells and healing of wound skins.

Description

technical field [0001] The invention relates to a skin care material, in particular to a collagen dressing and a preparation method thereof. Background technique [0002] With the improvement of the economic base and the improvement of aesthetics, the public's pursuit of beauty has led to an increasing demand for plastic surgery. With the development of medical technology, safer medical aesthetic treatments and more significant effects have also attracted more consumers. These medical cosmetology operations will cause skin inflammation, allergies, scar formation during wound healing, or pigmentation, so repair products are required after surgery. [0003] Collagen is a biopolymer synthesized by fibroblasts. It is the most abundant and widely distributed protein in the human body. It can promote the normal growth of epidermal cells, guide epithelial cells to move into defects, stimulate cell division, and make Its degradation products can be used by newborn cells to synthesi...
