1. A lancet device configured to exert a driving force on a lancet during a lancing cycle and used on a tissue site, the lancet device including electrical components, comprising:

  • a housing, the housing including a first housing and a second housing, where the first housing being larger than the second housing and the first and second housings having dissimilar shapes, the first housing configured to house a battery, and the second housing configured to house the electrical components, a lancet analyte sensor associated with the lancet;

    a processor coupled to a drive force generator, the processor and drive force generator positioned in the second housing, the drive force generator configured to be coupled to the lancet to advance the lancet along a path into the tissue site, create a penetration and a subsequent flow of a blood sample into a receiving channel of the second housing and then to the analyte sensor for analysis;

    a latching device that holds the a lancet from exiting the lancet device when the lancet device is not in use;

    a bearings guide associated with the lancet for accurately defining a lancing trajectory;

    a human interface input control configured to provide depth setting range for lancet penetration into the tissue site; and

    a human interface coupled to the drive force generator, the human interface position at the second housing, the human interface being a voice system which uses words to describe status or alarms related to the lancet device usage, the voice system including a sound generator configured to provide information to a user relative to at least one of a reminder when a next measurement of a blood sample is needed and an analytic measurement result of a blood sample.
