Abstract
An arrangement for producing a sample of body fluid from a wound opening created in a skin surface at a sampling site includes at least one skin-penetration member having a first end configured to pierce the surface of the skin, and a inner lumen in communication with the first end; at least one actuator operatively associated with the at least one skin-penetration member; and at least one catalyst device configured to cause perfusion of body fluid at the sampling site; wherein the at least one actuator is configured to locate the at least one skin-penetration member so as to obstruct the wound opening while transporting body fluid through the inner lumen. Associated methods are also described.

An arrangement for producing a sample of body fluid from a wound opening created in a skin surface, the arrangement comprising:
- a skin penetration member having a first end configured to pierce the skin surface, and a lumen in fluid communication with the first end;
- a spring actuator configured to drive the skin penetration member to form the wound opening, wherein the spring actuator has a neutral rest position and is configured to allow the skin penetration member to obstruct the wound opening when the spring actuator is in the neutral rest position;
- a needle hub connecting the skin penetration member and the spring actuator;
- and
- a compartment at least partially enclosing the skin penetration member, the spring actuator, and the needle hub.
An arrangement for producing a sample of body fluid from a wound opening created in a skin surface, the arrangement comprising:
- a skin penetration member having a first end configured to pierce the skin surface, and a lumen in fluid communication with the first end;
- and
- a torsional spring actuator configured to drive the skin penetration member in an arcuate path to form the wound opening, wherein the torsional spring actuator has a neutral rest position and is constructed and positioned such that the skin penetration member obstructs the wound opening when the torsional spring actuator is in the neutral rest position.
