[Technical Problem] It is an object to provide a cuff-equipped tube that can prevent a movement of a cuff as soon as practicably possible even in the case in which a force for moving the cuff or the tube is applied in the case in which a body posture of a patient is changed by way of experiment after the cuff-equipped tube is inserted into the affected part of the body and the cuff is expanded and positioned. [Solution of Problem] A cuff-equipped tube formed by providing a cuff to the outer periphery of a flexible tube, the cuff being expanded by introducing an operation fluid thereinto or being contracted by discharging the operation fluid therefrom. The cuff is provided with a cuff affixing portion expanded outward by the introduction of the operation fluid thereinto, and also with one mounting portion and the other mounting portion that are mounted to the outer peripheral surface of the tube. The connecting portions of the cuff affixing portion and the one mounting portion is affixed in a constricted shape to the outer peripheral surface of the tube, and the connecting portions of the cuff affixing portion and the other mounting portion is affixed in a constricted shape to the outer peripheral surface of the tube. In the case in which an external force is applied to the cuff affixing portion in a state in which the operation fluid is introduced to the cuff affixing portion and the cuff affixing portion is expanded, the distance between the one mounting portion and the other mounting portion is constant and does not change and the cuff affixing portion is located at a predetermined position. In the case in which the external force applied to the tube is removed, the cuff affixing portion returns to the original attitude. |
