摘要：
Plastic replacements for glass capillary tubes for drawing samples of blood or other body fluids are achieved by texturing the inside surface of the tube with uniform fine features and by extruding the tube over a suitably textured tapered pin with a (gradual) ratio of at least 6:1 during extrusion to ensure the transfer of the pin's surface texture to the inside diameter of the tube.
