Abstract

The invention relates to an anti-microbial and anti-swelling medical dressing and a preparation method thereof. The dressing comprises the following raw materials in part by weight: 18 to 25 parts of alginate fiber, 12 to 18 parts of glass fiber, 2 to 8 parts of the essential oil of Cymbopogon nardus, 12 to 20 parts of ethyl alcohol, 1 to 4 parts of Vitamin E, 0.2 to 0.4 parts of silver powder, 0.04 to 0.08 parts of safflower extract, and 8 to 24 parts of deionized water. The preparation method comprises the following steps of weighing the raw materials, adding the silver powder into the deionized water, stirring, adding the safflower extract, and continuously stirring to obtain a first mixture; mixing and stirring the essential oil of Cybopogon nardus and the Vitamin E, dropwise adding into the first mixture, heating to 37-42 DEG C, adding the alginate fiber and the glass fiber, and continuously stirring to obtain a second mixture; vacuum drying the second mixture to obtain the anti-microbial and anti-swelling medical dressing. The medical dressing is good in anti-microbial effect and strong in air permeability, and has practical value.

Description

technical field [0001] The invention belongs to the field of medical dressings, in particular to an antibacterial and detumescent medical dressing and a preparation method thereof. Background technique [0002] The skin is an important organ of the human body and acts as a barrier to protect the body. It protects various tissues and organs in the body from physical, mechanical, chemical and pathogenic microorganisms. In addition, the skin also has physiological functions such as sensation, secretion, excretion and temperature regulation. Therefore, when there is a problem with the skin, it should be taken care of as soon as possible, so that the skin can restore its tissue and function. [0003] Medical dressing is an article commonly used in skin wounds. There are many types of existing dressings and most of them are prepared with chemicals, which have side effects on the human body. Therefore, it is necessary to develop a natural, antibacterial and strong medical dressin...
