The pricking element (10): is withdrawn with uniform speed after the forward movement in a back pulling movement from the deepest pricking position into a back pulling position by smaller pricking depth； is withdrawn in the area of stratum corneums； and is moved backward during the collecting phase around 2-0.1 mm. The reception of the blood is controlled over the detection of the blood fluid contact, and a given collecting duration is awaited for the reception of the blood during the detection of the blood contact. The blood fluid contact is detected: at a renewed pricking in the point of reversal for the back pulling movement； in the back pulling position； in the area of the stratum corneums； by capacitive or inductive or resistive measuring parameters, capillary structure or a light conductor within the body part； over the pricking element and a contact element (30) standing in a unit with the body part； and over the pricking element by impedance measurement in relation to the skin. An error signal is generated in missing blood contact and the withdrawal of the blood is interrupted. The blood is received over the sting channel as a connection to a blood-giving zone of the body part. The duration of the back pulling phase is selected in the order of magnitude of the duration of the forward movement. The collecting phase is extended in relation to the back pulling phase around 10-10.000 times. The movement of the pricking element is controlled by time detection or position detection. An independent claim is included for device for removal of blood.
