The blood taking set comprises an intermediate store with a piston/barrel arrangement communicating with a throughflow channel of a catheter. A piston tip (11) and a tip (3) of the barrel space (2) are conically shaped. The cone angle (13) of the piston tip (11) is larger than the cone angle (12) of the barrel space (2). The piston tip (11) elastic is at least to the extent that the difference between the cone angles (12, 13) on pushing the piston tip (11) against the conical tip (3) of the barrel space (2) is eliminated. The barrel space is thereby emptied completely. <IMAGE> |
