Abstract

The utility model relates to the technical field of medical devices, which discloses a naso-biliary drainage tube with an air bag used for the drainage of the bile in a bile duct or the discharge of the residual stones in the bile duct. The utility model consists of the naso-biliary drainage tube (1) and the air bag (2), the naso-biliary drainage tube is divided into two parts of a body part (1.1) and a head part (1.2), the body part (1.1) is a dual-cavity tube, one side thereof is an inflation tube (1.3), the front end is communicated with the air bag for the inflation or deflation of the air bag, and the tail end is matched with a rubber plug (3) for the prevention of air leakage; the other side is a drainage tube (1.4) and is communicated with the head part, the air bag is wrapped at the junction of the body part and the head part of the naso-biliary drainage tube, and a drainage hole (4) is arranged on the tube wall of the drainage tube which is positioned at the front and the back of the air bag. The naso-biliary drainage tube has simple structure and convenient usage. The naso-biliary drainage tube can not have translocation and emersion when in placement or implanting of the drainage tube, if the indwelling process finds the residual stones in the bile duct, the air bag can be pulled out after inflation, and the residual stones can be dragged out of the bile duct.

Description

A kind of nose bile drainage tube with air bag

Technical field

This utility model relates to technical field of medical instruments, is a kind of nose bile drainage tube of the band air bag that is used for bile in the drain bile duct and retained calculus in the bile duct is hauled out.

Background technology

Acute obstructive suppurative cholangitis is common emergency and severe disease clinically, and endoscopic nasobiliary drainage art (ENBD) is the first-selection treatment measure of acute obstructive suppurative cholangitis.ENBD is a kind of easy, safe and effective biliary tract drainage way, it is that biopsy pipeline by scope inserts the front end of nose bile drainage tube in the biliary tract, the other end is drawn from the nostril, can not only drain infectious bile in the biliary tract, alleviate pressure of biliary tract, jaundice eliminating, control inflammation by nose bile drainage tube, and at any time radiography, repeatedly the flushing, drug infusion, effectively improve patient's whole body situation.Used nose bile drainage tube is the elongated pipe of a both ends open at present, and the head tube wall is provided with conduction hole, and front end is slightly thin, and tail end is connected to the syringe standard interface, and joining with syringe is used for extracting or injecting fluid.Its weak point is because of pipe is thinner, when inserting in the biliary tract, if the patient operates unskilled or cooperates inharmoniously, causes the drainage tube transposition easily, deviates from, and makes and places failure; Longer because of the drainage tube indwelling time again, the nose bile drainage tube head often occurs and deviate from bile duct, sb.'s illness took a turn for the worse to cause the drain interruption; It three is that normal the discovery had calculus remnants after ERCP got stone and places nose bile drainage tube, and drainage tube can not help calculus, and the patient need accept ERCP once more and get stone, not only easily leads to complications, and has increased patient's misery and medical expense.

Summary of the invention

The purpose of this utility model provide a kind of easy to use, can prevent the drainage tube transposition, deviate from and can help to discharge the nose bile drainage tube of the band air bag of retained calculus.

This utility model is made up of nose bile drainage tube and air bag, and nose bile drainage tube divides body and head two parts, and body is a double lumen tube, and the one side is a gas tube, and front end communicates with air bag, is used for to airbag aeration or aerofluxus, and tail end is joined a rubber closure 3, with anti-gas-leak; Opposite side is a drainage tube, communicates with head, and air bag is wrapped in the intersection of nose bile drainage tube body and head, and the drainage tube tube wall that is positioned at the air bag front and back is provided with conduction hole.During use, gas emptying in the air bag, go endoscopic nasobiliary drainage art (ENBD) routinely, the relevant position that the biopsy pipeline by scope inserts biliary tract with the front end of nose bile drainage tube, the other end is drawn from the nostril, give airbag aeration with syringe with the rubber closure 3 that syringe needle passes the gas tube tail end, extract syringe needle, air bag is full to be adjacent to bile duct wall, extracts scope more routinely, drainage tube can transposition, deviate from promptly feasible drainage.Earlier with air bag deflation, extract out routinely again during taking-up.

This utility model is simple in structure, easy to use, drainage tube insert or can transposition when keeping somewhere, deviate from, improved the success rate that drainage tube is inserted or kept somewhere, if finding has retained calculus in the bile duct, outer drawing behind the airbag aeration can be hauled out bile duct with retained calculus in the indwelling process, do not need once more intubate or be ERCP again and get stone, thereby alleviated patient's misery and financial burden.

The specific embodiment

Now in conjunction with the accompanying drawings and embodiments, this utility model is described in detail.

This utility model is made up of nose bile drainage tube 1 and air bag 2,1 fen body 1.1 of nose bile drainage tube and head 1.2 two parts, and body 1.1 is a double lumen tube, the one side is a gas tube 1.3, and front end communicates with air bag 2, is used for to airbag aeration or aerofluxus, tail end is joined a rubber closure 3, with anti-gas-leak; Opposite side is a drainage tube 1.4, communicates with head, and air bag is wrapped in the intersection of nose bile drainage tube body and head, and the drainage tube tube wall that is positioned at the air bag front and back is provided with conduction hole 4.During use, gas emptying in the air bag, go endoscopic nasobiliary drainage art (ENBD) routinely, the relevant position that the biopsy pipeline by scope inserts biliary tract with the front end of nose bile drainage tube, the other end is drawn from the nostril, give air bag 2 inflations the rubber closure 3 that syringe needle passes the gas tube tail end with syringe, extract syringe needle, air bag is full to be adjacent to bile duct wall, extracts scope more routinely out, drainage tube can transposition, deviate from promptly feasible drainage.Earlier with air bag deflation, extract out external more routinely during taking-up.

Embodiment 1.
