PROBLEM TO BE SOLVED: To facilitate insertion of an endoscope into an indwelling catheter. ! SOLUTION: An endoscope system 1 includes: an insertion portion 11 in which an imaging optical system and an illumination optical system are covered with a protection tube; an operational part 12 connected to a base end of the insertion portion; a solution sending means 20; and a joint 30. The joint includes: a first connector part 31 which is connected to a proximal end 103 of an indwelling catheter 100 indwelled in a human body; a second connector part 32 connected to an output end of the solution sending means; an insertion port 33 where the insertion portion is inserted; and a path 34 which communicates with the first connector part and communicates with the second connector part at one side and the insertion port at the another side via a confluence part. The insertion portion entering the path from the insertion port passes through the confluence part and the first connector part to be able to enter the indw |
