Abstract
A blood sampling device is provided with a housing, a lancet assembly, a lancet holder disposed in the housing for supporting the lancet assembly, the lancet holder being movable in a lancing direction between a cocked position and a puncture position, a drive spring for forcing the lancet holder from the cocked position to the puncture position, and a mechanism for damping movement of the lancet holder during travel of the lancet holder from the puncture position to an intermediate position between the puncture position and the cocked position. The damping mechanism may be provided in the form of a non-planar surface, such as a corrugated surface, disposed on the lancet holder and a damping member which makes contact with the non-planar surface during movement of the lancet holder.
