Blood withdrawal system for withdrawing blood for diagnostic purposes, comprising a housing with a lancet, which can be moved within the housing, and a lancet drive with a drive spring and a cocking mechanism, wherein the cocking mechanism (13) includes an actuation element (14), which is coupled through an input-side coupling mechanism (29) to the drive spring (16) such that the drive spring (16) is tensioned during a cocking phase of the motion of the lancet drive (9) by moving the actuation element (14). The actuation element of the cocking mechanism is coupled to a track control mechanism comprising as components of the track control mechanism a control track part (45) and a control traveller (46), wherein the control traveller (46) performs a relative motion with respect to the control track part (45) during at least a part of the cocking phase, in which motion it travels along the control track (47) of the control track part (45), whereby at least a part of the motion of the lancet drive is controlled. |
