Problems solved by technology

[0008] The purpose of the present invention is to overcome the fact that the nipples of breastfeeding women are often sucked by babies and secrete milk, and the skin near the wound is very moist, so that the dressings used for treating chapped nipples in the prior art are easy to fall off, which is not conducive to wound healing. To solve the problem, a breast-protecting bandage suitable for breastfeeding women and its preparation method are provided. Through the cooperation of moisture-absorbing layers and water-retaining layers with different components and structures, the breast-protecting bandage can quickly absorb nipple secretions and moisture, Make the wound heal in a moist environment, improve the healing rate of the wound, and the moisture-absorbing layer can effectively adhere to the skin, and it is not easy to fall off under the friction of clothes

Abstract

The invention relates to the technical field of medical dressings, and discloses a breast-protecting wound dressing suitable for lactating women and a preparation method thereof, comprising a back film, a water-retaining layer, a moisture-absorbing layer and a protective film arranged in sequence, and the moisture-absorbing layer is in parts by weight. The raw materials include 20~60 parts of graft copolymer of sodium carboxymethylcellulose, acrylic acid and acrylamide, 20~40 parts of rubber elastomer, 5~20 parts of mineral oil, 1~5 parts of antioxidant, 10~20 parts of Copovidone, 1-10 parts of foaming agent, raw materials of water-retaining layer include 20-60 parts of graft copolymer of sodium carboxymethylcellulose, acrylic acid and acrylamide, 5-10 parts of amidated pectin, 10-30 parts 1 part of rubber elastomer, 5~20 parts of mineral oil, 1~5 parts of antioxidant. The moisture-absorbing layer of the invention has rich pores, fast moisture-absorbing speed, and the wound sticker is not easy to fall off; the water-retaining layer has good gel strength, is not easy to decompose after absorbing water, provides a moist environment for wound healing, and accelerates healing.

Description

technical field [0001] The invention relates to the technical field of medical dressings, in particular to a breast-protecting wound dressing suitable for lactating women and a preparation method thereof. Background technique [0002] Cracked nipples are one of the common diseases during lactation, and the incidence rate is as high as more than 70% in lactating women. In mild cases, only cracks appear on the surface of the nipple, and in severe cases, local exudate and blood ooze. When the baby is sucking, the nipples will feel sharp pain and may bleed, and there may be local exudation and blood oozing, which will form small ulcers repeatedly, which can easily cause mastitis. When breastfeeding, there is often heart-piercing pain, and it is very easy to breastfeed. Premature mothers bring the fear of breastfeeding, which increases the discomfort of being a first-time mother. [0003] For chapped nipples during lactation, the existing solutions mainly include: 1.
