Detailed Description

The utility model is further described below with reference to fig. 1-6.

The cholecystography and pancreatography with the endoscope retrograde motion is the most common diagnosis and treatment technology in the digestive system department, and the common nursing means after the operation is to place the nasal bile duct to continuously drain bile to an external sterile drainage bag, and after the nasal bile duct is clinically directly inserted into the conical joint at the top end of the drainage tube and is placed into one section of the nasal bile duct, medical personnel often fix the nasal bile duct and the conical joint by winding an adhesive tape so as to avoid falling.

In the process, the nose bile duct is not matched with the interface and is easy to fall off, and medical care personnel are easy to be infected with bacteria in the process of using the adhesive plaster, so that cross infection and other diseases are caused.

The utility model provides a medical interface of a nasobiliary duct and a drainage bag, which comprises a first interface 1 and a second interface 2, wherein the first interface 1 is detachably connected with the second interface 2, the first interface 1 comprises a nasobiliary duct accommodating cavity 11 and a connecting column 12, a screwing lug 13 is arranged on the surface of the connecting column 12, a pipe orifice 5 for inserting the nasobiliary duct is arranged on the nasobiliary duct accommodating cavity 11, the connecting column 12 is connected with one end of the second interface 2, a screwing groove 14 is arranged on the inner wall of the second interface 2, the screwing lug 13 is matched with the screwing groove 14 to enable the connecting column 12 to be matched and fixed with the second interface 2, a cavity 3 is arranged in the second interface 2, and a fastening ring 4 is arranged at the other end of the second interface 2.
