1. A blood lancet apparatus with a base body for the arrangement of a plurality of apparatus components, comprising:

  • a lancet reception device for coupling the blood lancet apparatus to a lancet element;

    at least one lancet spring for acting upon the lancet reception device with spring force;

    an actuator for initiating a movement of the lancet reception device along a displacement direction that is substantially aligned with a longitudinal direction of the base body; and

    a detection device associated with the lancet reception device for emitting at least for a time at least one signal with respect to a fixing position of the lancet element coupled at least for a time and at least in part to the blood lancet apparatus, wherein the detection device is arranged inside the base body and arranged movable along the displacement direction with respect to the lancet reception device and comprises;

    a detection spring configured to store energy at least for a time, wherein the energy is capable of being discharged substantially abruptly; and

    an output device configured to change the coupling between the lancet reception device and the lancet element and to deflect the detection spring, wherein the output device comprises a rod-shaped element that allows and inhibits at least one of a friction locking or a positive locking between the lancet reception device and the lancet element,wherein the lancet reception device has at least one guidance for guiding the detection device in the displacement direction of the lancet reception device.
