PROBLEM TO BE SOLVED: To provide an obstructor for a tracheal fistula forming tube. SOLUTION: This plug 2 for a tracheal fistula forming tube 1 has a strap 25 extending in its longitudinal direction between a nose 21 of the end part 20 on the patient side and the end part 32 on the device side, and a clip 34 to be fixed to a coupling of the tube is provided on the end on the device side. The strap 25 comprises a first web 26 extending over the whole length and a second web 27, the second web 27 is extended at right angles to the first web 26, and forms a T-shaped section toward the end on the patient side along a major portion 28 of the strap 25. This means that the rigidity is relatively given to the end part 20 on the patient side of the strap 25, the flexibility is given to the other end part on the device side, the clip 34 is disengaged by twisting the end part on the device side, and the obstructor 2 can be drawn from the tube. |
