Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a double-chamber nasobiliary drainage tube capable of draining bile into the intestinal cavity and out of the body. Background technique [0002] Acute obstructive suppurative cholangitis is a common acute and severe disease in the Department of Gastroenterology. For the above-mentioned diseases, relieving biliary obstruction as soon as possible and draining suppurative bile are the primary treatment measures. At present, endoscopic nasobiliary drainage (ENBD) is the preferred treatment. [0003] ENBD is a simple and effective way of external bile drainage. It uses endoscopic technology to put the front end of the nasobiliary duct into the biliary tract, and the other end is led out from the nose. The infectious bile in the bile duct can be drained through the nasobiliary drainage tube to relieve biliary obstruction. , subside jaundice, control inflammation, and through ...
