Abstract
A syringe for obtaining a target volume of blood is presented. The syringe () comprises a barrel (), wherein a plunger () is arranged within the barrel () to be displaceable along a displacement direction (X). Furthermore the barrel () and the plunger () together provide for a first stop () and second stop (), wherein the first stop () is configured for positioning a filter () at a predetermined location along the displacement direction (X) thereby defining a target volume of blood and a buffer volume. Moreover, the second stop () is configured to stop the plunger () from expelling more than the buffer volume from the syringe () for obtaining the target volume of blood when the plunger () is pushed towards the distal end () of the syringe () along the displacement direction (X). In addition, the syringe () facilitates that the syringe () fills itself with the target volume of blood by a self-filling procedure using blood that is under pressure, like arterial blood, and using the filter () located in the plunger ().
