Abstract: A tube cutting and separating implement for a conduit comprising a grasping body formed to insert the conduit therethrough and having a first section separable from a separating portion and a second section. The first and second sections respectively have first and second flow stopping portions for grasping the conduit to stop the flow and first and second holding portions for holding the flow stopping state. A cutter is disposed at the first or second section at a position displaced from the flow stopping portions for cutting the conduit. Thus, the implement can stop flow at two positions of the conduit by a simple operation and cut the conduit and separate the implement into two sections so as to allow a patient to simply and rapidly be released without loss of blood in case of an emergency.
