Description

Multi-side hole spiral type nasal biliary drainage tube

Technical Field

The utility model relates to the technical field of nasal biliary drainage tubes, in particular to a multi-side hole spiral nasal biliary drainage tube.

Background

Retrograde Cholangiopancreatography (ERCP) via an endoscope is one of the main means for minimally invasive treatment of biliary-pancreatic diseases at present. On the basis of ERCP, can carry out interventional therapy such as bile duct lithotomy, bile duct stent implantation, endoscopic Nasal Bile Drainage (ENBD), etc., because ERCP operation does not need to be operated, the wound is little, and the hospitalization time is also shortened greatly, is welcomed by the patient.

The nasal biliary drainage tube is needed to be used in Endoscopic Nasal Biliary Drainage (ENBD), and the nasal biliary drainage tube produced by different manufacturers at present has a pig tail type and a straight head type. The nose biliary drainage tube with the front end in the shape of a pigtail is provided with a ring similar to the shape of the pigtail at the front end, and the diameter of a bile duct of a normal person is about 8mm, so the nose biliary drainage tube with the shape of the bent pigtail can not be coiled into a bend or is supported to the bile duct when being coiled, and thus the pain is felt by the patient. Because the front end of the nose-liner drainage tube of the straight head is straight, the nose-liner drainage tube of the straight head for the bile duct which is expanded and unexpanded has the risk of easy slipping and displacement. The front end of the straight head is left at the bile duct section relatively short, the side holes are less and easy to be blocked, and the nasal bile duct drainage is poor.

Therefore, a novel nasal biliary drainage tube is needed to solve the problems that the side hole is poor in drainage effect, the straight head is easy to shift, and the pig tail has pain to a patient.

Disclosure of Invention

The utility model aims to provide a multi-side hole spiral type nasal biliary drainage tube so as to solve the problems in the background technology.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the utility model provides a many side openings spiral nose gall drainage tube, includes the drainage tube, the end of drainage tube is provided with the screw segment, the end of screw segment is provided with the mouth of pipe, it has a set of side openings to distribute on the screw segment.

Further, a short straight section is arranged between the tail end of the spiral section and the pipe orifice, and a side hole is also arranged on the straight section.

Further, a long straight section is arranged between the tail end of the spiral section and the pipe orifice, and a side hole is also arranged on the straight section.

Further, the drainage tube and the spiral section are of round hollow tubular structures, and the outer diameters of the drainage tube and the spiral section are 5Fr-10Fr.

Further, the length of the drainage tube is 230-270cm.

Further, the number of the side holes on the spiral section and the straight section is not less than 8.

Further, the pipe wall of the pipe orifice is thin and is arranged into a conical structure of a cone.

Compared with the prior art, the utility model has the beneficial effects that:

1. according to the multi-side hole spiral type nasal biliary drainage tube, the problem that the drainage effect is poor due to the fact that the number of side holes is small can be solved, more side holes can be designed at the spiral head end for drainage of bile, and the drainage effect is better;

2. according to the utility model, the spiral type nasal biliary drainage tube can solve the problem that the straight head nasal biliary drainage tube is easy to shift or slip. The straight head is not bent, so that the straight head is easy to shift or slip when placed in a bile duct, and the drainage effect is affected. The spiral nasal biliary drainage tube is not easy to shift because the spiral coil can be attached to the wall of the biliary tube to have certain tension;

3. in the utility model, the spiral nasal biliary drainage tube can not have large tension when coiled like the shape of a pig tail, so that patients have pain. The spiral coil has small radius and small tension, and can reduce pain of patients when placed in bile ducts.

In conclusion, the nasal biliary drainage tube device has the advantages of good drainage effect, small risk of slipping or displacement, capability of reducing pain of patients, suitability for placing the nasal biliary drainage tube device with and without the expansion of biliary tracts, simple structure, simple and convenient operation and popularization value.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1: referring to fig. 1-2, a multi-side hole spiral type nasobiliary drainage tube comprises a drainage tube 1, wherein a spiral section 2 is arranged at the tail end of the drainage tube 1, a tube orifice 4 is arranged at the tail end of the spiral section 2, and a group of side holes 5 are distributed on the spiral section 2.

According to the utility model, the drainage tube 1 and the spiral section 2 are plastic hoses with shaping functions, the drainage tube 1 is matched with an oral-nasal exchange tube and a drainage bag device for use, the problem of poor drainage effect due to few side holes can be solved through the multi-side hole 5, and more side holes can be designed at the head end of the spiral section 2 for drainage of bile, so that better drainage effect is ensured.
