Endoscopic helicobacter pylori vital staining diagnostic solution, preparation method and use

Abstract

The present invention provides an endoscopic Helicobacter pylori vital staining diagnostic solution, as well as its preparation method and application, wherein the diagnostic solution comprises: urea at a concentration of 10%-20% (w / v); anthocyanin red at a concentration of 3%-8% (w / v); konjac glucomannan at a concentration of 0.1%-0.5% (w / v); and maltodextrin at a concentration of 2%-10% (w / v). The diagnostic solution achieves rapid, uniform, high-contrast, and long-lasting specific staining in active Hp regions (the active regions of Helicobacter pylori infection show a specific purple coloration), thereby providing endoscopists with clear and stable visual diagnostic evidence and extending the effective time window for observation and operation.
