Abstract

The nanometer silver spray for women consists of distilled water, nanometer silver powder, foaming agent, foaming assistant and propellant, and is prepared through dispersing nanometer silver powder into distilled water, adding foaming agent and foaming assistant, filling, and adding propellant. The present invention applies the medicine deeply and makes the medicine foam without flow to maintain long time, and this can prolong the medicine retaining time in the disease focus part to reach high curative effect. The present invention is suitable for use in preventing and treating bacterial, fungal and trichomonad diseases.

Description

technical field [0001] The invention relates to a spray for treating gynecological diseases, in particular to a nano-silver spray for women; [0002] The invention also relates to a method for preparing the spray. technical background [0003] Nano-silver powder belongs to nano-precious metal particles, which refers to the powder composed of metal silver particles with a particle size between 1 and 100nm, also known as ultra-fine precious metal particles. The excellent performance of nano-silver powder particles depends on its unique microstructure. Nano-silver particles have significant surface effects, quantum size effects and macroscopic quantum tunneling effects, so they show biological, thermal, optical, electrical, Magnetic, catalytic, and sensitive properties enable it to be used in many fields such as biomedicine, optics, electronics, optoelectronic materials, catalysts, and magnetic materials. [0004] Silver has been widely used in the field of biomedicine since ...
