Abstract

The invention relates to medical super-hydrophobic antibacterial dressing and a method for preparing the same, and relates to the field of medical products. The method for preparing the medical super-hydrophobic antibacterial dressing includes placing dressing in alkaline buffer solution with dopamine and preparing polydopamine-modified first dressing samples by the aid of self-polymerization of the dopamine; placing the first dressing samples in solution with fluorine modifiers, and carrying out reaction to obtain fluorine-embellished polydopamine-modified second dressing samples; placing thesecond dressing samples in silver ionic solution, and carrying out reaction so as to carry out reduction on silver ions on polydopamine to obtain silver nanometer particles. The medical super-hydrophobic antibacterial dressing and the method have the advantages that the medical super-hydrophobic antibacterial dressing can be easily and controllably operated, and the sterilization and anti-adhesion purposes can be achieved by the medical super-hydrophobic antibacterial dressing under the control of the method at different wound healing phases; the medical super-hydrophobic antibacterial dressing is excellent in hydrophobic property and antibacterial property and can be used as acute wound or infected wound dressing.

Description

technical field

[0001] The invention relates to the field of medical products, and in particular to a medical superhydrophobic antibacterial dressing and a preparation method thereof. Background technique

[0002] Gauze is one of the commonly used materials in hospitals. Now hospitals generally use single-layer degreased gauze, which has the following problems: First, according to the traditional weaving method, the stretchability is poor, and the gauze is made of cotton fibers. If it is not replaced for a long time, it is easy to breed bacteria, cause re-infection of the wound, and slow down the healing speed of the wound; secondly, due to the single-layer absorbent cotton structure, it is easy to absorb water when it encounters water. , it is easy to cause wound inflammation, and at the same time, the secretion of the wound sticks to the gauze. It is very easy to breed bacteria, cause wound re-infection, and cause great harm to patients. In modern prevention and treatment...
