Single-puncture lancing system

A lancing device, comprising:

• a housing including a movable housing and a main housing, the main housing forming an inner cavity enclosing a portion of a lancing mechanism, the lancing mechanism being adapted to move between a resting position, a cocking position, and a puncture position, the lancing mechanism including a lancet holder affixed to a shaft having an enlarged end opposite the lancet holder, the housing enclosing at least one spring surrounding at least a portion of the shaft, the at least one spring having a first portion and a second portion, the second portion of the at least one spring being configured to engage the lancet holder, the housing further enclosing a plate positioned between the first portion and the second portion of the at least one spring, the first portion and second portion of the at least one spring being configured to engage and extend on opposite sides of the plate, the plate being distinct from the lancet holder and the shaft moving with respect to the plate when the lancing mechanism moves between the resting position, the cocking position, and the puncture position, the at least one spring being adapted to drive the lancing mechanism between the cocking position and the puncture position, the first portion of the at least one spring damping the lancing mechanism as the lancing mechanism moves from the puncture position to the resting position,
• wherein the movable housing is adjacent to the main housing, the movable housing being adapted to move from a resting position to a cocking position, the movable housing forming an inner cavity enclosing a portion of the shaft of the lancing mechanism.
