  • a housing defining a capillary channel with an opening configured to draw a body fluid via capillary action;

    a lancet for forming an incision in a front side of a finger, the finger has a backside that is opposite the front side, the lancet being slidably disposed within the housing; and

    a pad secured to the housing, and aligned with the lancet such that the slidable motion of the lancet is in the direction of the pad, the pad having a first angled surface interconnected to an opposing second angled surface wherein deflection of the interconnection causes the first surface to deflect toward the second surface to compress only the backside of the finger to express the body fluid from the incision without compressing the front side of the finger.
