Cartridge device for a measuring system for measuring viscoelastic characteristics of a sample liquid, a corresponding measuring system, and a corresponding method

A cartridge device for a measuring system for measuring viscoelastic characteristics of a sample liquid, in particular a blood sample, comprising:

• a cartridge body having at least one measurement cavity formed therein and having at least one probe element arranged in said at least one measurement cavity for performing a test on said sample liquid;
• and
• a cover being attachable on said cartridge body;
• wherein said cover covers at least partially said at least one measurement cavity and forms a retaining element for retaining said probe element in a predetermined position within said at least one measurement cavity;
• wherein said probe element is formed as a detachably fixed component part of the cover having a fixing section for detachably fixing said probe element at fixing means of said cover;
• and
• wherein said fixing section of said probe element is integrally formed with said cover, said fixing means of said cover comprising a perforation.
