A MEASURING UNIT FOR MEASURING CHARACTERISTICS OF A SAMPLE LIQUID, IN PARTICULAR VISCOELASTIC CHARACTERISTICS OF A BLOOD SAMPLE

摘要

The present invention is directed to a measuring unit (1) for measuring characteristics of a sample liquid (44), in particular viscoelastic characteristics of a blood sample, comprising a support member (2) having at least one upper bearing arm (3) with an upper bearing unit (14), at least one lower bearing arm (4) with a lower bearing unit (21) and a base (5) for being attachable to a respective measuring system (40); a shaft (10) having shaft toes (11, 12) and being rotatably supported about a rotation axis (20) by said upper bearing unit (14) and said lower bearing unit (21), wherein said upper bearing unit (14), said lower bearing unit (21) and said shaft toes (11, 12) form toe bearings, respectively; an interface member (24) having a detecting element (31) and a drive element (32), said interface member (24) being fixed on said shaft (10) and being connected to a coupling shaft (35) with a probe connector section (37) for measuring characteristics of said sample liquid (44); wherein said interface member (24) and the coupling shaft (35) are coaxially aligned with said shaft (10). The present invention is also directed to a corresponding measuring system (40).
