ていた。 When in use, it should have an outer diameter slightly larger than the outer diameter of the blood collection tube (tube for collecting blood), and a blood sedimentation tube smaller than the outside diameter of the blood sedimentation tube should be inserted into the center and locked relatively firmly. Use a rubber stopper with a hole for insertion of a blood sedimentation tube. That is, as shown in FIG. 6, the blood sedimentation tube 9 is inserted and locked into the rubber stopper 8, inserted into the blood collection tube 4 containing blood, and the blood sedimentation tube 9 with the rubber stopper 8 is advanced to an appropriate position in the blood collection tube 4. By doing so, the blood level was raised to the zero scale.
