A liquid conveying catheter for conveying a liquid from an object from which the liquid is to be collected, the catheter comprising:
- a collecting tube having an insert end adapted to be inserted into the object for sucking a liquid;
- a mixing bar extending through the collecting tube and rotatably supported;
- and
- a drive unit for rotating the mixing bar,
- wherein the collecting tube has a helical convex on its inner wall around the center axis of the collecting tube, so as to define a helical groove serving as a flow path.
A liquid conveying catheter for supplying a liquid and collecting a liquid to/from an object, the catheter comprising:
- a supply tube having an insert end adapted to be inserted into the object for discharging the liquid;
- a collecting tube having an insert end adapted to be inserted into the object simultaneously with the supply tube, for sucking the liquid;
- a mixing bar extending through the collecting tube and rotatably arranged;
- and
- a drive unit for rotating the mixing bar,
- wherein the collecting tube has a helical convex on its inner wall around the center axis of the collecting tube, so as to define a helical groove, serving as a flow path.
A liquid conveying catheter as claimed in one of the foregoing Claims, wherein a suction pump is provided at the insert end and opposite end of the collecting tube.
