Coloring agent for mucous membrane of digestive tract, and preparation method and application thereof

Abstract

The invention relates to the field of detection, in particular to a coloring agent for a mucous membrane of the digestive tract, and a preparation method and application thereof. The coloring agent for the mucous membrane of the digestive tract provided by the invention comprises a first coloring pigment and a second coloring pigment, wherein the first dyeing pigment comprises a blue pigment, andthe second dyeing pigment comprises a red pigment. When the coloring agent provided by the invention is used for staining, a stained color is obviously different from the color of the mucous membrane,tiny concave-convex changes of the mucous membrane can be well displayed, various raised, flat and sunken focuses and three-dimensional structures thereof are displayed, strong stereoscopic impression is presented, details in the digestive tract can be clearly recognized, focus boundaries can be clearly recognized, and the detection rate of lesions is remarkably increased. Besides, the coloring agent for the mucous membrane of the digestive tract provided by the invention is extremely easy to clean and few in residues after washing, enables an operation field to be clear, and has a relativelygood clinical application value.

Description

Technical field [0001] The invention relates to the field of detection, in particular to a digestive tract mucosal stain, a preparation method and application thereof. Background technique [0002] Gastrointestinal diseases are common diseases that endanger human health. In severe cases, they can even cause death. Among them, the incidence and mortality of gastric cancer are among the top cancers in the world. The prognosis of gastrointestinal diseases is directly related to the diagnosis stage.

Problems solved by technology

However, indigo carmine is blue and has a large color difference with the color of the digestive tract mucosa (close to pink to white). After dyeing, the visual gap is too strong, which may easily cause blurred surgical field and is not easy to clean.

[0008] In short, due to the design defects of the existing gastrointestinal mucosa stains, there are some shortcomings in the application. The market urgently needs a stain that has obvious staining effects, is safe and effective, and does not affect the surgical field.
