Abstract

A tube restoring apparatus includes a tube insertion passage through which a connected flexible tube having a deformed cross-sectional portion at a joint portion thereof can be passed, at least a pair of press members defining at least a part of the tube insertion passage and formed with press surfaces for pinching the deformed cross-sectional portion of the flexible tube therebetween, and driving mechanism for moving the press surfaces at least in opposite directions relative to each other under the condition that the deformed cross-sectional portion is pressed between the press surfaces. In the apparatus, the deformed cross-sectional portion of which inner surface is fused or stuck by a tube connecting device is disposed between the press surfaces of the press members, and then the press members are moved by the driving mechanism so as to press or roll back and forth the deformed portion of the tube to tear off or separate the fused or stuck portion between the press surfaces, thereby restoring the deformed portion to ensure fluid communication within the tube.
