1. A lancing device comprising:
- a main housing including a spring stop and a guide mechanism, the main housing forming an inner cavity enclosing a drive spring, a guide rib, a casing, and at least a portion of a lancet holder, the casing being coupled to the lancet holder, the casing defining an internal space, the lancet holder being configured to receive a lancet therein, the lancet holder being spaced from the spring stop, the drive spring being positioned between the lancet holder and the spring stop such that a portion of the drive spring is disposed within the internal space of the casing, the drive spring being detached from the spring stop and being detached from the lancet holder, the drive spring being configured to drive the lancet holder in a first direction of travel from a cocked position to a puncture position along an axis, the guide rib being configured to engage the guide mechanism to aid in guiding movement of the lancet holder from the cocked position to the puncture position;
a movable housing coupled to the main housing such that a portion of the movable housing is inside of the main housing and such that a portion of the main housing is inside of the movable housing, the movable housing being configured to move between a first position and a second position, wherein movement of the movable housing from the first position to the second position causes the lancet holder to move from a resting position to the cocked position; and
a biasing system including a damping spring, the damping spring being configured to move the lancet holder from the puncture position to the resting position, the damping spring, the drive spring, and the lancet holder being aligned along the axis.

Abstract
A lancing mechanism is adapted to move between a resting, cocking and a puncture position. The lancing mechanism comprises a lancet holder adapted to receive a lancet, a shaft attached to the lancet holder, at least one drive spring and at least one damping spring. The drive spring surrounds at least a portion of the shaft and drives the lancing mechanism from the cocking position to the puncture position. The damping spring moves the lancing mechanism from the puncture position to the resting position. The drive spring is located at least partially within the damping spring.
