Abstract
A lancing mechanism is adapted to move between resting, cocking and puncture positions and comprises a lancet holder, a shaft, at least one spring and a mass. The shaft is attached to the lancet holder and has an enlarged end opposite the lancet holder. The spring surrounds at least a portion of the shaft and has first and second portions. The second portion of the spring is attached to the lancet holder. The spring drives the lancing mechanism between the cocking and puncture positions. The mass is located along the spring with the first and second portions of the spring extending on opposite sides of the mass. The mass is distinct from the lancet holder. The first portion dampens the lancing mechanism when moving from the puncture position to the resting position.
