An insertion device has pivotable elongated members manipulable by a hand, one of which holds a trocar, and the other a target through which the trocar will pass as the elongated members are pivoted. A tube is connected to the trocar or elongated member holding the trocar, and the tube is passed through body tissue from a position interior to the body to a position exterior to the body, together with the trocar. An end of the tube is positioned in a fluid accumulating area of the body, and passes to a container external to the body. The container contains markings which enable a determination of the quantity of passed fluid. At intervals, the quantity of fluid is determined, and the container is replaced with another container.
