Sterile liquid dressing and preparation method thereof

Abstract

A sterile liquid dressing and a preparation method thereof belong to the technical field of medical liquid dressings and preparation thereof. The preparation method comprises the following steps: dissolving 9 g of sodium chloride in 200-400 g of pure water by stirring to form a sodium chloride solution and controlling the mass% concentration of the sodium chloride solution to obtain a first solution; dissolving 0.001-10 g of stabilizer to 100-250 g of pure water by stirring to form a second solution; adding the second solution to the first solution or adding the first solution to the second solution and stirring, subsequently adding 0.125-10 g of sodium hypochlorite solution and continuing stirring to obtain a mixed solution, then adding 4-10 ml of hydrochloric acid to adjust the pH valueof the mixed solution, and finally, adding pure water to a constant quantity of 1000 g, and carrying out sterile filling after membrane filtration to obtain the sterile liquid dressing. An ideal sterilization effect is achieved; pathogenic microorganisms are killed; the preservation time of hypochlorous acid is delayed; the steps are simplified; and the invasion of bacteria which can be introducedin the production process is prevented.

Description

technical field [0001] The invention belongs to the technical field of medical liquid dressing and its preparation, in particular relates to a sterile liquid dressing, and also relates to its preparation method. Background technique [0002] The skin is the largest organ in the human body. The skin of an adult has an expanded area of ​​about 2 square meters and weighs about 16% of the body weight. It protects various tissues and organs in the body from physical, mechanical, chemical and pathogenic microorganisms. The skin has two barrier functions: one is to prevent the loss of water, electrolytes and other substances in the body; the other is to prevent the invasion of harmful substances from the outside. The skin maintains the stability of the internal environment of the human body, and the skin also participates in the metabolic process of the human body. [0003] With the development of society, various traumas, senile diseases, and metabolic diseases are becoming mor...

Problems solved by technology

[0005] Because hypochlorous acid is used in the formula of the above-mentioned document CN109907069A, the bactericidal effect of the above-mentioned document CN105969795B and CN109010907B will be inferior to that of CN109907069A, but this CN109907069A has many and complicated raw materials to choose, and the preservation or maintenance time of hypochlorous acid is short. Insufficient, and did not give beneficial enlightenment on how to accelerate the speed of wound healing and the comprehensive effect of avoiding wound infection
