device for measuring the erythrocyte sedimentation rate.

摘要

A device for measuring the sedimentation rate of blood particles (BSR) of a blood sample (2) which has been rendered incapable of clotting provides for the use of an extraction syringe (1). In order to create a closed system, the sedimentation tube (9) also forms at the same time the syringe piston rod of this extraction syringe (1). In this case, the sedimentation tube (9) is surrounded, in the non- reading region, by a sleeve (11), which is sealed off at its lower end by a shaped-on projection which exhibits a central aperture (14). In this case, the sedimentation tube (9) is insertable into the sleeve (11) as far as this projection. In order to prevent the blood sample (2) from flowing out during the measurement, a closure element is associated with the aperture (14). IMAGE
