Medical bandage having bactericidal and itching-relieving function and preparation method

Abstract

The invention discloses a medical bandage having a bactericidal and itching-relieving function and a preparation method. The medical bandage is prepared from, by weight, 20-30 parts of a polyurethane prepolymer, 6-13 parts of sophora flavescens, 5-9 parts of honeysuckles, 4-8 parts of common cnidium fruits, 3-6 parts of cassia twigs, 4-7 parts of yam rhizomes, 9-13 parts of fructus forsythiae, 7-12 parts of glabrous greenbrier rhizomes, 3-7 parts of camptotheca acuminata, 5-10 parts of passepartout, 4-9 parts of humulus scandens and an appropriate amount of a defoaming agent. The obtained medical bandage product is free of toxic and side effects, good in air permeability and good in moisture absorption, has no bad irritation to a human body, has parasite-killing, sterilizing, itching-relieving, calming, palpitation-relieving, inflammation-diminishing, stasis-removing and symptom-eliminating effects and so on, has good biological compatibility and can effectively kill bacteria on the surface of the skin, prevent skin swelling and itching, prevent wound infection and provide a dry and comfortable healing environment for a patient, enables the patient to feel comfortable in use and is convenient to use.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to a medical bandage with bactericidal and antipruritic functions and a preparation method thereof. Background technique [0002] As a typical product of medical textiles, bandages can prevent wound re-injury, properly regulate the temperature and humidity of the wound, reduce complications and prevent infection during the natural healing process, and make the injured feel comfortable. Studies by trauma physiologists have shown that maintaining a certain humidity in the wound is conducive to the proliferation of skin cells and accelerates wound healing. During the wound healing process, the wet environment can prevent the excessive contraction and scarring. The large amount of body fluid exuded from the wound at the beginning can easily cause bacteria to multiply and cause infection. Therefore, it is very necessary to effectively absorb these body fluids and maintain a sterile envir...
