Apparatus for measuring haemostasis for detecting abnormal blood coagulation has device causing shear motion among adjacent parts of blood sample and detector measuring torque between holder and device

摘要

Apparatus for measuring haemostasis has a blood sample holder, a device causing shear motion among adjacent parts of a blood sample and a detector measuring torque between the holder and the device. Apparatus for measuring haemostasis has a blood sample holder, a device causing shear motion among adjacent parts of a blood sample, a detector measuring torque between the holder and the device. The apparatus has a drive ring around a torque sensing column. A holder for a sample cup assembly is movably attached to a first guide shaft extending parallel to the column and rigidly secured to the ring. An outer surface of the assembly engages the holder and its inner surface engages the sensing element.
