Patent ID: 8916110

Claim:
A device ( 1 ) for separating constituents of a sample fluid ( 2 ), comprising: a receiving device ( 4 ) for receiving the sample fluid ( 2 ), a separating device ( 3 ) for separating constituents of the sample fluid ( 2 ), the sample fluid ( 2 ) being adapted to be supplied to the separating device ( 3 ) from the receiving device ( 4 ), and a structure ( 5 ) provided downstream of the separating device ( 3 ) for draining the sample fluid ( 2 ) after constituents have been separated off, wherein the receiving device ( 4 ) comprises a receiving region ( 7 ) for metering, stopping or delaying the sample fluid ( 2 ) by capillary force and/or a chemical ( 13 ) that can be dissolved by the sample fluid ( 2 ), in order to pre-treat the sample fluid ( 2 ) before it is supplied to the separating device ( 3 ), wherein the receiving region ( 7 ) comprises a sloping ramp ( 9 ) and an associated cover ( 11 ), and a guide region ( 10 ) that is arranged at or terminates at a spacing above the separating device ( 3 ), which operate to stop or delay the sample fluid ( 2 ), and wherein the receiving region ( 7 ) includes a guide element ( 16 ) that is foldable over at least one of the receiving device ( 4 ) and the separating device ( 3 ) in order to provide a fluidic connection between the receiving region ( 7 ) and the separating device ( 3 ).
