Abstract

A lancing device for drawing a body fluid sample from the skin that comprises a body portion, an endcap, a lancet and a vibration member. The endcap detachably connects to the body portion. The lancet is located within the body portion in a retracted position. The lancet is moveable between a retracted position and an extended position, and adapted to draw body fluid sample from the skin at a puncture site in an extended position. The vibration member extends through the endcap and is adapted to mechanically vibrate the skin adjacent to the puncture site. The lancet is adapted to draw the body fluid sample from the skin at a puncture site by extending through an opening formed in the endcap, the vibration member or the combination thereof. One example of a vibration member is a piezoelectric member.
