Mucous membrane staining system

Abstract

The invention discloses a mucous membrane staining system. A first staining fluid bottle (1) is connected with a first connector of a first tee joint (5) through a first pipeline (3), a second connector of the first tee joint (5) is connected with a second staining fluid bottle (2) or a flushing fluid bottle (6) through a second pipeline (4), and a pump tube (7) is connected to a third connector of the first tee joint (5), installed on a first power device (8) and connected with a flushing tube (9) or / and a spraying tube (10). A first switching device (11) is connected between the first pipeline (3) and the second pipeline (4). The functions of gastrointestinal tract mucous membrane flushing cleaning and gastrointestinal tract mucous membrane staining are integrated and can be rapidly switched, several modes are provided for selection, the diagnosis and treatment efficiency of a gastrointestinal endoscope and comfort of a patient can be improved, missed diagnosis and misdiagnosis can be easily reduced, the examination rate of a digestive tract early cancer is increased, and meanwhile accurate treatment under the gastrointestinal tract endoscope is facilitated.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and specifically relates to a mucosal dyeing system. Background technique [0002] Chromoendoscopy is based on conventional endoscopic examination to stain the mucosa, so that the color contrast between the lesion and the normal mucosa is more obvious, which is helpful for the identification of lesions, biopsy and microscopic diagnosis and treatment. Mucosal stains commonly used in clinic include indigo carmine, compound iodine solution, methylene blue and crystal violet. The commonly used clinical staining method is to spray and stain suspicious lesions with syringes and spray tubes. [0003] The existing clinical staining methods have the following deficiencies: [0004] (1) The method of staining the lesion with a syringe is generally sprayed only when the lesion is seen, which is easy to miss diagnosis, and it is very difficult to stain the whole intestine; [0005] (2) It is diffi...

AI Technical Summary

Problems solved by technology

[0004] (1) The method of staining the lesion with a syringe is usually sprayed only when the lesion is seen, which is easy to miss diagnosis, and it is very difficult to stain the whole intestine;

[0005] (2) It is difficult to control the amount of dyeing agent used in the dyeing method with a syringe. Generally, it is either too much or too little. Too much waste and too little can cause missed diagnosis;

[0006] (3) Wash with dye neutralizer (such as sodium thiosulfate solution) after double dyeing or dyeing, and replace the syringe, which is troublesome;

[0008] (5) Before staining, it is complicated and time-consuming to prepare the mucous membrane of the lesion with a syringe using a temporary prepared foam-removing and mucus-removing solution.
