Description

technical field

[0001] The invention relates to a first-aid wound dressing, and also relates to a preparation method of the dressing. Background technique

[0002] With the advancement of material science and technology, the research on medical dressings has also achieved rapid development. Traditional emergency wound dressings are mainly made of cotton products. Although cotton dressings have the characteristics of strong water absorption, good heat resistance, and excellent alkali resistance, they are also easy to shrink after absorbing secretions, and easy to cause wounds due to pollution. Infection, easy to adhere to the wound surface and cause secondary trauma and other shortcomings, and because it is an inert dressing, it has no obvious effect on promoting the healing of the wound (Li Xiaoyang, Zhu Peifang, Hu Jianian. Development and evaluation of new burn dressings. Biomedical Engineering Journal 1994;11(1):5). People are actively exploring and researching other na...
