ABSTRACT:
A detaching tool for a tube for medical treatment includes a body for gripping which has generally a U-shape and is resiliently deformable in an opening-closing direction in a bent portion. A separating member is separably disposed inside the body and the separating member generally forms a C-shape and is adapted to be pressed and closed by the body for gripping when the body for gripping is closed. A tube inserting portion is formed in the body and the separating member so that a tube for medical treatment may be inserted and held therein. First and second stream stopping portions are provided at a corresponding location inside the body and a corresponding location inside the separating member so as to press the pertinent portion of the tube and stop a stream inside the tube when the body is closed. First and second holding portions are provided on the body and the separating member so as to maintain the stream stopping states of the first and second stream stopping portions when the body is closed. A cutter for cutting the tube upon closing of the body is provided between the first and second stream stopping portions. A stopper is provided for preventing the cutter from arriving at the tube for a gripping force of a predetermined value or less.
