Abstract

A kind of nose bile drainage tube that this utility model relates to, comprise the drainage tube (1), quick change locking female Luer (3) that are provided with conduction hole (2), it is characterized in that: described conduction hole (2) is dispersed on the column tube wall of the front portion of drainage tube in the shape of a spiral; The caliber of the far-end body of the body that described drainage tube (1) is anterior is slightly less than the caliber of rear end body.By the pipe diameter determing that front end is comparatively tiny, it is made to be easy to enter the narrow and small caliber of single tube major papilla, simultaneously owing to taking helical form to scatter the conduction hole on drainage tube, can ensure that conduction hole that drainage tube all can not cause because of the dirty extruding of device under any state is by the appearance of whole closed phenomenon; Obviously this is very effective for the normal drainage of the whole device of maintenance.

Description

A kind of nose bile drainage tube

Technical field

This utility model relates to a kind of nose bile drainage tube, with inserted by nasal passage-indwelling drainage tube makes temporary Microendoscopic biliary drainage, belongs to medical instruments field.

Background technology

Endoscopic nasobiliary drainage (Endoscopic Nasobiliary Drainage, ENBD) sets up on the basis of diagnostic retrograde cholangiography (ERCP) technology, is the scope biliary drainage method comparatively commonly used.Its adopts the elongated plastic tube in one end to insert in bile duct through vater's papilla under scope, the other end through duodenum, stomach, esophagus, pharynx etc. from the lead body of nostril, the external drainage setting up bile by way of.ENBD is the method for simple and effective releasing obstruction of biliary tract, reaches decompression, subtracts Huang, the object of antiinflammatory by drain., safely and effectively biliary drainage and biliary tract backwashing manner simple to operate as one, can not only abundant bile drainage, and can rinse bile duct, carries out drug infusion, repeatedly carries out cholangiography, effectively improves entire patient's situation.Be widely used in clinical at present, become the biliary tract such as obstructive jaundice, acute pyogenic cholangitis, the highly effective endoscopic therapeutic methods of pancreatic diseases.The nose bile drainage tube far-end of current employing adopts the bending location of pig tail type or straight type to insert location; its weak point is conventional nose bile drainage tube; the structure of its conduction hole is generally Bilateral Symmetry structure; in actual operation operating process; the drainage tube of Bilateral Symmetry structure often can cause drainage tube to be closed because of the extruding of internal organs inside; thus reduce the effect even losing bile drainage, not only easily cause complication, also can increase misery and the financial burden of patient.

Utility model content

In order to solve the technical problem existed in above-mentioned use, the purpose of this utility model aims to provide a kind of gallbladder drainage tube, conveniently, is easy to enter bile duct major papilla position and the novel nose bile drainage tube that can effectively prevent drainage function from losing.

To achieve the above object, this utility model have employed following technical scheme:

This nose bile drainage tube, comprises the drainage tube 1, the quick change locking female Luer 3 that are provided with conduction hole 2, it is characterized in that: described conduction hole 2 is dispersed on the column tube wall of the front portion of drainage tube in the shape of a spiral.

The caliber of the far-end body of the body of described drainage tube 1 front portion is slightly less than the caliber of rear end body.

According to this nose bile drainage tube that above technical scheme proposes, not only pass through the comparatively tiny pipe diameter determing in front end, it is made to be easy to enter the narrow and small caliber of single tube major papilla, simultaneously owing to taking helical form to scatter the conduction hole on drainage tube, can ensure that conduction hole that drainage tube all can not cause because of the dirty extruding of device under any state is by the appearance of whole closed phenomenon; Obviously this is very effective for the normal drainage of the whole device of maintenance.

Detailed description of the invention

Further describe this utility model below in conjunction with Figure of description, and provide embodiment of the present utility model.

This nose bile drainage tube as shown in the figure, it is a kind of inventive improvements to the existing congenerous nose bile drainage tube generally used.

This nose bile drainage tube, comprises the drainage tube 1, the quick change locking female Luer 3 that are provided with conduction hole 2, as long as its inventive improvements is embodied in following two aspects:

One, is dispersed on the column tube wall of the front portion of drainage tube in the shape of a spiral by the conduction hole 2 be arranged on drainage tube 1.The benefit of such design is: in actual use, once its front end enters after in bile duct, because the conduction hole 2 on drainage tube 1 scatters in the shape of a spiral, therefore, when bile duct is subject to the extruding of a direction external dirty body human intracavity, only there is the conduction hole on this direction to be closed, lose diversion function; The conduction hole of its other party is then still in conducting state, ensures that drainage function proceeds.

Its two, become by the caliber of drainage tube 1 front end comparatively thin, rear end is comparatively thick, ensures its mating with external device.The design that this front end is thinner, is conducive to gallbladder drainage tube and enters bile duct major papilla position quickly and easily, ensures that surgical drainage carries out fast.

Claims

1. a nose bile drainage tube, comprise the drainage tube (1), quick change locking female Luer (3) that are provided with conduction hole (2), it is characterized in that: described conduction hole (2) is dispersed on the column tube wall of the front portion of drainage tube in the shape of a spiral.

2. a kind of nose bile drainage tube as claimed in claim, is characterized in that: the caliber of the far-end body of the body that described drainage tube (1) is anterior is slightly less than the caliber of rear end body.
