A haemodialysis unit suitable for use in an artificial kidney machine has a blood conduit which has a wall of semi-permeable material on each of closely spaced opposite sides and plastics material sheet outside and on each side of the conduit. The sheet on each side provides, with a wall of semi-permeable material on that side, walls of a passage for dialysing liquid. On each side of the conduit the sheet has parallel liquid flow-directing ribs which are directed towards and into contact with the wall of semi-permeable material. The ribs on one side of the conduit are at an angle to the ribs on the opposite side. The blood conduit may be in the form of a tube or tubes of semi-permeable material and this may be coiled together with a length of a novel form of plastics material sheet which has ribs on both sides, the ribs on one side of the sheet being at an angle to the ribs on the other side.
