Cartridge device for a measuring system for measuring viscoelastic characteristics of a sample liquid, a corresponding measuring system, and a corresponding method
First Claim
1. A cartridge device for evaluation of hemostasis, comprising:
- a plurality of cavities each configured to receive blood of a test sample, each cavity comprising a reagent or combination of reagents;
ductwork, including an inlet for receiving a test sample, wherein the ductwork is in communication with each of the plurality of cavities, whereby each of the plurality of cavities is configured to receive, via the ductwork, a portion of the test samplea first cavity of the plurality of cavities comprising a first reagent or a first combination of reagents that interact with the blood received therein, wherein the first reagent, or a reagent included in the first combination of reagents, is an activator of coagulation;
a second cavity of the plurality of cavities comprising a second combination of reagents that interact with blood of the test sample received therein, the second combination including an activator of coagulation and one or more reagents configured for suppressing thrombocyte function; and
a viscoelastic interrogation device that measures blood clot firmness of the test sample or other parameters dependent on measurement of blood clot firmness.

Abstract
The present invention is directed to 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. The invention is directed to a measurement system and a method for measuring viscoelastic characteristics of a sample liquid.
