| 摘要 |
A blood sedimentation device has a cylindrical blood reception vessel (16), a transparent sedimentation tube (11) whose lower end can be inserted in the cylindrical blood reception vessel (16), and a tube piston (14) which is seated, tightly on the inside and displaceably, on the sedimentation tube (11) and can be inserted, tightly on the outside and displaceably in the blood reception vessel (16). At the top the sedimentation tube (11) is terminated by a flow restrictor (28, 31) which permits the build-up in the upper end of the sedimentation tube (11) of an air cushion which restrains the blood column from rising on abrupt insertion of the tube piston (14) into the blood reception vessel (16). <IMAGE>
