The lancing mechanism includes a lancet holder (36) attached to a shaft (38) and a drive spring (42) surrounding a portion of the shaft (38). The lancing device (10) also includes a movable housing (14) adjacent the main housing(12). The moveable housing (14) has an internal surface enclosing a portion of the shaft (38) of the lancing mechanism. The enclosed portion of the shaft (38) has a retainer (40) and a secondary spring(46) surrounding at least a section of the shaft (38). The secondary spring (46) is adapted to move the movable housing (14) from a cocking position to a resting position. The secondary spring (46) is further adapted to move the lancing mechanism from a puncture position to a resting position. |
