Digestive tract mucosa stain

Abstract

The invention discloses a digestive tract mucosa stain, which is an aqueous solution of indigotindisulfonate sodium. The gastrointestinal tract mucosa stain can deposit in the surface of gastrointestinal tract and opening of a glandular tube, so that a distinct contrast is formed between the stained mucosa surface and the unstained part; the unstained bumps among the opening of the glandular tube are easy to wash, and can be repeatedly stained until satisfaction. The mucosa stain is not absorbed by gastrointestinal tract mucosa, and has no side effect.

Description

Technical field [0001] A reagent used to stain gastrointestinal mucosa. Background technique [0002] Since Japanese scholar Tsuda and others first created a pigmented endoscopy that spreads pigment under direct vision, it has made up for the shortcomings of ordinary endoscopy, can obtain the exact morphological characteristics of the intestinal mucosa, provide accurate targets for clamping mucosal specimens, and improve the intestinal Diagnosis of gastrointestinal diseases, especially gastrointestinal tumors. In the early 1980s, the positive diagnosis rate reached 80%, and the highest rate was 90%. [0003] The working principle is as follows: the surface of the normal gastrointestinal mucosa is smooth, but when there are minor lesions, such as ulcers, cancer, etc., the surface will change, but in the early stage, due to the small changes, it is difficult to use ordinary endoscopy Find. The coloring agent uses the principle of contrast. When the coloring agent is sprayed on the...
