The blood sampling device consists of a blood sampling tube (1) with a screw cap (2), which has an attachment (3) for receiving a needle adapter, a piston (4) guided in the tube (1) and a piston rod (5) connected to the piston. At the point of connection to the piston the piston rod (5) has a predetermined breaking point (5.1). Provided on the blood sampling tube (1) between the frontmost and rearmost piston positions are markings (1a, 1b) which in each case indicate partial volumes of the full tube volume. The piston rod has at least one further predetermined breaking point (5.2, 5.3) which is in each case assigned to a marking (1a, 1b). In this way it is possible also to take up partial volumes of blood which do not correspond to the full tube volume. <IMAGE> |
