    摘要： A device is constructed so as to define a capillary channel that draws a body fluid form a proximal portion of the capillary channel toward a distal portion. A counterbore defining a “ledge” not substantially normal to the center line of channel causes the meniscus of body fluid to be “biased” into a non-radially-symmetric shape. In one example, the bias draws the body fluid toward a testing element that is set into a groove in the main body of the device. In another example, hydrophilic and/or hydrophobic regions are created on or in device to produce the biasing effect. In certain configurations, device requires less blood to be drawn into the capillary channel for a successful test than if the biasing effect were not created.

    摘要： An arrangement of interfitting components for adjusting the penetration depth of a lancet and for stimulating an area surrounding an incision formed by penetration of a surface of the skin by the lancet, thereby facilitating the extraction of a sample ofbodily fluid with a minimally invasive incision, the arrangement includes: a bottom end adapted to be applied to the surface of the skin, and a top end opposite the bottom end; a longitudinally moveable lancing member having a sharp end; a stop member setting a longitudinal travel distance of the lancing member; a bottom surface adapted to be applied to the surface of the skin, and an opening in the bottom surface through which the lancing member projects; a penetration depth defined by the distance between the end of the lancing device and the bottom surface; an adjusting mechanism for changing the penetration depth; and a stimulation mechanism for stimulating the area surrounding the incision and facilitating the extraction of the sample of bodily fluid.
