Sample collection device
First Claim
1. A sample collection device for the collection and analysis of the coagulation time of capillary blood taken directly from a patient with the aid of a capillary, comprising a unitary combination of a) through f):
- 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
i) recording the coagulation time of the blood in the internal memory of the analyzer.

Abstract
In order to provide a sample collection device (100) for the collection of capillary blood directly from the patient or for taking a sample from a liquid with the aid of a capillary (16) so that it is made possible to perform analyses of the sample free from volume errors within the sample area and free from contamination, it is proposed that the capillary (16), for the absorption of sample liquid to be analyzed, be connectable with the aid of a mounting means (100) with a cuvet (10) possibly containing a reagent liquid.

18. A sample collection device for the collection of an accurately measured amount and analysis of capillary blood taken directly from a patient or from a liquid with the aid of a capillary, comprising a unitary combination of a) through e):
-
a) a capillary for the absorbtion by capillary attraction of an accurately measured amount of sample liquid to be analyzed, b) a cuvet; c) a means for mounting said capillary on said cuvet; and d) a pressure cap means for creating a pressure at one end of the capillary which transfers the blood in the capillary into the cuvet; and e) a means for analyzing said sample liquid within said cuvet without removing said capillary and mounting means.
