Nasobiliary drainage device

Abstract

Disclosed is a nasobiliary drainage device. The problems are effectively solved that the time and effort are consumed in the connection of current drainage bag joints, the current drainage bag joints easily fall off, drainage tubes are contaminated, the drainage amount is recorded inaccurately, the color interpretation is inconsistent, and the judgement of clinical related complications is affected. The nasobiliary drainage device comprises a drainage tube, a spiral joint is arranged on the upper portion of the drainage tube, the bottom of the spiral opening of the spiral joint is concave, the lower end of the spiral joint is connected with the drainage tube, the drainage tube is provided with a specimen maintaining and fetching opening located below the spiral joint, the right end of the specimen maintaining and fetching opening is connected with a cover cap, the lower end of the drainage tube is connected with a kettle part, and the lower end of the kettle part is provided with a fluid discharge switch. The drainage device can be effectively prevented from slipping, the color of drainage fluid is observed conveniently, a specimen of the drainage fluid can be conveniently maintained and fetched, the work efficiency of medical staff is improved, the occurrence of nosocomial infection is reduced, and the risk of related occupational exposure is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a nasobiliary drainage device. Background technique [0002] Endoscopic retrograde cholangiopancreatography [0003] ERCP) is widely used in the diagnosis and treatment of a variety of hepatobiliary and pancreatic diseases. It has the advantages of small trauma and fast postoperative recovery, but it may also bring a series of complications. Post-ERCP pancreatitis (post-ERCP pancreatitis) , PEP) is the most common and dangerous complication, and the incidence of PEP in high-risk patients can reach 30%~50%. In recent years, studies have found that endoscopic nasobiliary drainage (ENBD) can effectively reduce the incidence of postoperative PEP , it is to insert a thin plastic tube into the bile duct through the duodenal papilla under the endoscope, and the other end is led out of the body through the duodenum, stomach, and esophagus through the nose, so as to establish...

AI Technical Summary

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a nasobiliary duct drainage device, which effectively solves the problem of time-consuming and labor-intensive connection of the current drainage bag connector, which is easy to fall off, pollutes the drainage tube, inaccurately records the drainage volume, and has problems with color interpretation. Inconsistent, issues affecting judgment of clinically relevant complications
