Abstract

The invention discloses melamine cross-linked polyvinyl alcohol hydrogel dressing which is prepared from, by weight, 3-9 parts of water retention films, 1-8 parts of medical pressure-sensitive adhesive, 2-8 parts of acetylsalicylic acid, 2-12 parts of melamine cross-linked polyvinyl alcohol hydrogel, 1-6 parts of mupirocin, 4-12 parts of wood pulp cellulose, 2-6 parts of vitamin A, 4-12 parts of vitamin E, 4-8 parts of protein, 0.2-1 part of perfume essential oil, 0.2-0.8 part of lemon essence and 0.2-1.2 parts of mint essential oil. The melamine cross-linked polyvinyl alcohol hydrogel dressing has good water solubility and conglutination, and can better promote cell growth, acetylsalicylic acid has an antiinflammation effect, the high-performance hydroscopicity of wood pulp cellulose is far better than that of common gauze, vitamin A, vitamin B and protein accelerate blood circulation, skin ageing is relieved, and the essential oil can fade scars and can also make people pleasure. The dressing can promote cell growth and repair and heal wounds, meanwhile can fade scars and whiten and tender skin, is remarkable in treatment effect, has no side effect and is wide in prospect.

Description

Technical field [0001] The invention relates to the technical field of hydrogel dressings, in particular to a melamine cross-linked polyvinyl alcohol hydrogel dressing. Background technique [0002] With the development of medical technology, more and more dressings are used. Traditional dressings have high permeability, which can easily cause dehydration of the wound, stick to the wound, and cause re-mechanical damage when replaced. Microorganisms in the external environment can easily pass through and cause cross infection. The opportunity is high, the dosage is large, the replacement is frequent, time-consuming, and the patient is painful. Hydrogel dressings have only been developed in recent years. It is a new type of wound dressing composed of high water content water-absorbent polymer gel. It can automatically adjust the moisture of the wound, has the ability to absorb a small amount of exudate, and does not stick to the wound. Easy to remove. However, the functions of th...
