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 a measuring system for measuring viscoelastic characteristics of a blood sample, comprising:
- a cartridge body including a receiving cavity for receiving the blood sample, a first blood transport path configured to receive a first portion of the blood sample via the receiving cavity, and a second blood transport path configured to receive a second portion of the blood sample via the receiving cavity;
the first blood transport path including a first reagent cavity containing a first reagent, a first measurement cavity having a first probe element arranged therein for measuring viscoelastic characteristics of the first portion of the blood sample, and a first duct connecting the first reagent cavity to the first measurement cavity; and
the second blood transport path including a second reagent cavity containing a second reagent, a second measurement cavity having a second probe element arranged therein for measuring viscoelastic characteristics of the second portion of the blood sample; and
a second duct connecting the second reagent cavity to the second measurement cavity,wherein the first and second blood transport paths are arranged in parallel.
