46. An arrangement for producing a sample of body fluid from a wound opening created in a skin surface at a sampling site, the arrangement comprising:
-
a housing, the housing comprising a first opening; a skin interface member disposed in the second opening, the skin interface member comprising a longitudinally tapered cylindrical member having a first opening constructed an arranged to be contacted by the skin, the inner diameter of the cylinder decreasing along the longitudinal direction away from the second opening, the longitudinally tapered cylindrical member comprising a plurality of longitudinal slits thereby forming a plurality of longitudinal sections, the longitudinally tapered cylindrical member constructed and arranged so as to be movable within the first opening upon pressing against the surface of the skin at the second opening thereby forcing the longitudinal sections radially inward; and at least one skin-penetration member configured and arranged to project within the second opening.

48. An arrangement for producing a sample of body fluid from a wound opening created in a skin surface at a sampling site, the arrangement comprising:
-
a housing, the housing comprising a first opening; a skin interface member disposed in the first opening, the skin interface member comprising a plurality of rotatable members defining a gap therebetween, the plurality of rotatable members constructed an arranged such that rotatable members are forced toward one another upon being pressed against the skin thereby decreasing the gap and pinching the skin; and at least one skin-penetration member configured and arranged to project within the gap.
