Embodiment Construction

[0083] Parts and components with the same function are described with the same reference numerals.

[0084] Before describing the preferred embodiment in detail, the basic features and basic practical implementation are summarized below. All embodiments relate to the cartridge device 50 (see Figure 13c ), which can be used in the first embodiment (see Figure 4 , 5 and 6), in the second embodiment (see Figure 7b , 7C and 15) or in the third embodiment (see Figures 9 to 10). The cartridge device 50 contains all parts that come into contact with the sample liquid 1 to be tested. These may also be reagents with which the specimen fluid must be mixed for measurement. Cartridge device 50 is measurement system 40 (see Figure 13c ), the cartridge device 50 is connected to the measurement system 40 before measurement. The measurement system 40 also includes a control device (not shown) which has been adapted to interact with the cartridge device 50 by electrical and / or mechan...

Abstract

The present invention is directed to a cartridge device (50) for a measuring system (40) for measuring viscoelastic characteristics of a sample liquid (1), in particular a blood sample, comprising a cartridge body (30) having at least one measurement cavity (20, 20') formed therein and having at least one probe element (22, 22') arranged in said at least one measurement cavity (20, 20') for performing a test on said sample liquid (1); and a cover (31) being attachable on said cartridge body (30); wherein said cover (31) covers at least partially said at least one measurement cavity (20, 20') and forms a retaining element for retaining said probe element (20, 20') in a predetermined position within said at least one measurement cavity (20, 20'). The invention is directed to a measurement system (40) and a method for measuring viscoelastic characteristics of a sample liquid (1).

Description

technical field [0001] The present invention relates to a cartridge device for a measuring system for measuring the viscoelastic characteristics of a sample liquid, especially a blood sample liquid. The invention also relates to a corresponding measuring system and method. Background technique [0002] Survival requires wound hemostasis, that is, the body has a sound hemostasis mechanism. The process of blood coagulation is activated by exogenous or endogenous factors (such as tissue factor (TF) or Hagman factor or contact factor (FXII) respectively in the case of injury or inflammation. The two activation pathways (activation channel) continues into a common branch of the cascade, leading to the formation of thrombin. Thrombin itself ultimately triggers the formation of fibrin fibers, which represent the protein backbone of the blood clot. [0003] The other major constituents of the eventual blood clot are platelets, which are interconnected by fibrin fibers and undergo ...
