  • a) a capillary for the capillary attraction into the capillary of a predetermined quantity of blood to be analyzed directly from the patient;

    b) a cuvet;

    c) a reagent liquid contained within said cuvet;

    d) an agitator member contained within said cuvet and surrounded by said reagent liquid;

    e) a means for mounting said capillary, said mounting means comprising;

    a capillary holder, said capillary holder retaining said capillary in a position disposed on said cuvet and extending into said cuvet with a plug-like section of said capillary holder, said capillary holder possessing an extension on the side facing away from said cuvet in the center of said capillary holder; and

    f) a protective and pressure cap longitudinally displacable on and in pressure sealable relationship with said extension of said capillary holder, the downward movement of the pressure cap creating a gas pressure in the capillary which forces blood in the capillary into the reagent;

    g) a measuring canal for the cuvet; and

    h) an analyzer having an internal memory, the analysis process of which is activated by entry of blood into the cuvet; and
