Provided is a tube with cuff being able to practicably prevent the cuff from moving even if the cuff or the tube is applied with any force that is to move the cuff or tube due to an alteration of patient’ s body position or the like after the tube with cuff is inserted into an affected area and the cuff is inflated to try to position the cuff, wherein tube with cuff 1 is provide with cuff 4 that is inflated or deflated by introducing or discharging operating fluid upon the external circumference of flexible tube 2, and cuff 4 comprises cuff fixing portion 22 that inflates outwardly through the introduction of the operating fluid and one attaching portion 10 and another attaching portion 11 attached upon the circumferential face of tube 2, in which connecting member 16 of attaching portion 10 and cuff fixing portion 22 is fixed upon the circumferential face of tube 2 in a slender posture, and a connecting member of another attaching portion 11 and cuff fixing portion 22 is fixed upon the circumferential face of tube 2 in a slender posture, and during a condition where cuff fixing portion 22 is introduced with the operating fluid and inflated thereby, when an external force is applied onto cuff fixing portion 22, the interval of attaching portion 10 and another attaching portion 11 of cuff 4 is remained the same without any change and cuff fixing portion 22 is positioned at a given location, and when the external force applied onto tube 2 is released, cuff fixing portion 22 is returned to the original posture.本發明提供一種附設護套之管，其係在將附設護套之管插入患部並使該護套膨脹而謀求護套之定位後，縱使有病患之體位改變時等，而使護套或管移動之外力作用時，亦可儘量防止護套之移動。本發明之附設護套之管(1)係在可撓性之管(2)的外周具備因作動流體之導入或排出而膨脹或收縮之護套(4)者，護套(4)係具備：因作動流體之導入而朝外側膨脹之護套固定部分(22)；及安裝在管(2)之外周面的一方安裝部分(10)及另一方安裝部分(11)；一方安裝部分(10)與護套固定部分(22)之連結部(16)係以中間較細之姿勢固定在管(2)之外周面，且另一方安裝部分(11)與護套固定部分(22)之連結部係以中間較細之姿勢固定在管(2)之外周面，在作動流體導入至護套固定部分(22)且護套固定部分(22)膨脹之狀態下，對護套固定部分(22)施加外力時，護套(4)之一方安裝部分(10)及另一方安裝部分(11)的間隔係為一定而不會變化，且護套固定部分(22)係位於預定位置，且在解除對管(2)施加之外力時，護套固定部分(22)會回復原來之姿勢。
