Water bladder irrigation drainage tube

Abstract

The invention discloses a water-bag type nose-bile flushing drainage tube. The drainage tube comprises a main tube, a pipeline I and a balloon film, the pipeline I is located inside the main tube and provided with a closed end, and the outer wall of the main tube is sleeved with the balloon film. The cross section of the balloon film is in a plum blossom shape, a pipeline II communicated with the balloon film is further arranged inside the main tube, multiple lateral holes I and multiple lateral holes II are formed in the main tube and located in the pipe section part, above the balloon film, of the main tube, and the lateral holes II and the pipeline I are communicated. Automatic flushing is achieved, the oval lateral holes are adopted for reducing the probability of blockage, the flowing direction of flushing fluid in the bile duct is uniform with the discharging direction of bile, and it can be avoided that the flushing fluid and the bile reversely flow. The balloon film capable of being expanded and filled is arranged, in this way, the fixing force of the drainage tube is increased, an anti-slipping effect is achieved, and damage to the bile duct, intestinal canal and pharynx and larynx mucosae will not be caused in the process of taking out the drainage tube.

Description

technical field [0001] The invention relates to a flushing and drainage tube, in particular to a water bag type nasal gallbladder flushing and drainage tube. Background technique [0002] 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 common bile duct stones, acute obstructive suppurative cholangitis, bile duct injury , biliary stricture, biliary complications after liver transplantation, etc. Compared with traditional laparotomy, this technique has the advantages of less trauma, high safety factor, and faster recovery. After ERCP treatment, external nasobiliary drainage tubes are routinely placed to drain infectious bile, bile sludge, and gravel, which can reduce the incidence of postoperative cholangitis and the recurrence rate of choledocholithiasis. [0003] At present, the nasal and bilia...

AI Technical Summary

Problems solved by technology

[0003] At present, the nasal and biliary drainage tubes in clinical use are all single-channel drainage tubes. The body of the tube is straight, and the head end is bent into a loop. Under the action, bile can be drawn out through the lumen, but the flow rate of bile is slow, and viscous purulent bile is not easy to discharge, and its circular side hole is small, and debris can easily block the side hole of the drainage tube

This drainage tube has the following deficiencies: 1. In order to keep the drainage tube unobstructed and promote the discharge of viscous purulent bile, it is necessary to repeatedly use physiological saline to rinse the nasobiliary duct after the operation, so as to keep the drainage tube unobstructed and dilute the intrahepatic bile , promote the discharge of viscous purulent bile and gravel, and increase the clinical workload; 2. Since the drainage tube is straight, when the bile is sucked, the bile duct wall mucosa is easily adsorbed to the side hole of the drainage tube, resulting in backwashing of the flushing fluid Difficult; 3. The head of the drainage tube is naturally looped, and its fixation force is small, and the drainage tube is prone to prolapse; 4. During the extubation process, the head of the loop drainage tube can cause damage to the bile duct and intestinal mucosa, and even induce Acute cholangitis, acute pancreatitis, upper gastrointestinal bleeding and other complications
