ABSTRACT:
Perforations at the insertion end portion of a suction drainage tube for draining body fluids are of a shape bounded on at least two opposite sides by the edges of helical land portions of the tubing wall. One or more helical slots or a pattern of diamond-shaped openings may accordingly be provided. Twisting the tube after its insertion can be done to dislodge obstructions that may build up. In withdrawing the tube, the diameter tends to be reduced, thus facilitating removal.
