Description

Technical Field

[0001] The utility model relates to the technical field of flushing converters, in particular to a bile duct flushing converter. Background Art

[0002] The bile duct is the general term for the duct that carries bile from the liver to the duodenum. It is divided into two parts: the intrahepatic bile duct and the extrahepatic bile duct. Biliary stones are the most common disease in the bile duct system, including gallbladder stones, common bile duct stones and intrahepatic bile duct stones. After bile duct stone surgery, the stones in the bile duct need to be flushed out to keep the common bile duct open.

[0003] However, there is currently a lack of suitable converters for bile duct flushing, which results in the need to first inject flushing fluid, and then discharge the flushing fluid carrying stones through the same tube after a period of time, resulting in low flushing efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a bile duct flushing converter to solve the existing problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bile duct flushing converter, comprising a conversion tube, the outer side of the conversion tube is provided with a fixing sleeve, threaded joints are provided on both sides of the conversion tube, one group of the threaded joints are threadedly connected to the outer sides with a threaded connection sleeve, and another group of the threaded joints are provided with a protective sleeve on the outer side, a drainage tube is provided on one side of the threaded connection sleeve, a flushing tube is provided on one side of the top of the conversion tube, and a positive pressure needleless connector is provided on the top of the flushing tube.

[0006] Preferably, one side of the flushing tube extends 8 to 10 cm into the drainage tube and can be trimmed when in use according to needs.

[0007] Preferably, a pin is provided on the inner side of the fixing sleeve, so as to fix the conversion tube in a suitable position for use.

[0008] Preferably, the material of the conversion tube is polyurethane or polyvinyl chloride, and the length of the conversion tube is 8 to 10 cm.

[0009] Preferably, the length of the threaded joint is 3 cm.

[0010] Preferably, the threaded joint is in the shape of a truncated cone.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the bile duct flushing converter cooperates with each other among the conversion tube, the fixing sleeve, the threaded joint, the protective sleeve, the positive pressure needleless joint, the flushing tube, the drainage tube and the threaded connection sleeve, so that the device can connect the positive pressure needleless joint to the infusion set for continuous bile duct flushing, and can also connect to the syringe for manual flushing. By connecting a set of threaded joints to the negative pressure drainage device to discharge the flushing liquid, the flushing liquid can be discharged while the liquid is injected and flushed, and the flushing is very convenient. When the device is not used for flushing, the protective sleeve can protect the threaded joint to prevent the pipeline from being contaminated. BRIEF DESCRIPTION OF THE DRAWINGS
