Y-type bile pancreatic juice drainage tube with water bag

Abstract

The invention discloses a Y-type bile pancreatic juice drainage tube with a water bag. The Y-type bile pancreatic juice drainage tube comprises a water bag type bile outer drainage tube and a pancreatic juice inner drainage tube. The water bag type bile outer drainage tube comprises a drainage tube section I, a drainage tube section II and a drainage tube section III. The drainage tube section II is sleeved with a balloon film, and the pancreatic juice inner drainage tube comprises a drainage tube body and a tube cap I located at the upper end of the drainage tube body. The side wall of the drainage tube body is connected with the side wall of the drainage tube section I through a connecting part. The Y-type bile pancreatic juice drainage tube has the effects of preventing the water bag type bile outer drainage tube from disengaging and preventing the pancreatic juice inner drainage tube from shifting or disengaging, is suitable for bile ducts of various diameters and has no injury to the bile duct mucous membrane, the duodenal papilla and the upper digestive duct mucosa in the placing-in and taking-out processes, bile duct obstruction will not be caused while the water bag type bile outer drainage tube is prevented form shifting, and while the water bag type bile outer drainage tube is taken out, the pancreatic juice inner drainage tube can be taken out.

Description

technical field [0001] The invention relates to a drainage tube device, in particular to a Y-shaped bile and pancreatic juice drainage tube with a water bladder. Background technique [0002] At present, with the continuous development of endoscopic technology and the continuous improvement of its accessories, duodenoscopy (ERCP) has become an important measure for the treatment of hepatobiliary and pancreatic diseases, including choledocholithiasis, bile duct injury, bile duct stricture, and liver transplantation. Posterior biliary complications, etc. Compared with traditional laparotomy, this technique has the advantages of less trauma, high safety factor, and faster recovery. Under direct vision, it can detect hepatobiliary and pancreatic diseases that cannot be detected by conventional liver, gallbladder, spleen and pancreas CT, ultrasound and magnetic resonance examinations, and treat them at the same time, such as duodenal papillitis, papillary stenosis, parapapillary...

AI Technical Summary

Problems solved by technology

[0005] The head of the nasobiliary drainage tube currently used clinically can entangle itself in the bile duct, but the stimulation of the head of the drainage tube to the bile duct mucosa can lead to local mucosal reactive hyperplasia; during the extubation process, the head of the drainage tube can cause bile duct and Injury to the intestinal mucosa can even induce complications such as acute cholangitis, acute pancreatitis, and upper gastrointestinal bleeding; irritation of the throat by the drainage tube often leads to severe nausea and even vomiting in patients
