The utility model provides a nose gall drainage tube, which comprises: the first drainage tube 10, the second drainage tube 20, the lock catch 30 and the traction piece 40. One end of the first drainage tube 10 is detachably connected with the second drainage tube 20 through a lock catch 30. The traction piece 40 is connected with the lock catch 30, and the traction piece 40 penetrates through the second drainage tube 20 and is led out through the second drainage tube 20. When the pulling member 40 pulls the locker 30, the locker 30 is disengaged from the second drainage tube 20 and the first drainage tube 10, and the second drainage tube 20 and the first drainage tube 10 are separated from each other.
The nose-gall drainage tube is divided into two sections, namely, the first drainage tube 10 and the second drainage tube 20, when the nose-gall drainage tube is used, one part of the first drainage tube 10 is placed in a biliary tract, for example, the rear part of the first drainage tube is arranged in a duodenum, the second drainage tube 20 is led out of a nasal cavity along an upper digestive tract, bile can be drained from the body to the outside of the body at the moment, after a plurality of days, when the bile is required to be drained into the duodenum, the traction piece 40 is pulled, the traction piece 40 drives the lock catch 30 to move in the outside direction, at the moment, the lock catch 30 is separated from the second drainage tube 20 and the first drainage tube 10 respectively, the second drainage tube 20 and the traction piece 40 are separated from each other, the second drainage tube 20 and the traction piece 40 are slowly pulled out of the upper digestive tract, the first drainage tube 10 is still left in the body, and the bile can be drained into the duodenum at the moment. Therefore, secondary operation is not needed, operation can be facilitated, and cost and operation risk are reduced.
Referring to FIG. 2, in one embodiment, the nasobiliary drainage catheter further includes a first connector 50 connected to one end of the first drainage catheter 10 and a second connector 60 connected to one end of the second drainage catheter 20. The first connector 50 and the second connector 60 are detachably connected by the latch 30. Thus, when the pulling member 40 is pulled, the pulling member 40 drives the lock catch 30 to move in the external direction, and at this time, the lock catch 30 is separated from the first connecting member 50 and the second connecting member 60, so that the first connecting member 50 and the second connecting member 60 are separated from each other, and the second drainage tube 20 and the first drainage tube 10 are separated from each other.
Referring to fig. 2, in one embodiment, the first connecting member 50 is a first connecting tube, and the second connecting member 60 is a second connecting tube. The first connecting pipe and the second connecting pipe are connected in a sleeved mode. Thus, after the first connecting pipe and the second connecting pipe are mutually sleeved and connected, the first drainage pipe 10 and the second drainage pipe 20 can be mutually combined together, and the tightness of the butt joint part is ensured.
Referring to fig. 2, in one embodiment, the first connection tube includes a first insertion section 51 and a first docking section 52 that are connected to each other. The first insertion section 51 extends into the first drainage tube 10, and the outer wall of the first insertion section 51 and the inner wall of the first drainage tube 10 are respectively provided with first barbs 53 and are connected with each other.
