Patent ID: 8360993

Claim:
A method of sampling body fluid from a wound opening created in a skin surface at a sampling site, the method comprising: providing an arrangement comprising a plurality of skin-penetration members and a plurality of pre-cocked torsional spring actuators, wherein each of the plurality of torsional spring actuators has a neutral rest position; automatically or manually initiating a testing sequence; actuating a first of the plurality of skin-penetration members with a respective torsional spring actuator such that the torsional spring actuator moves from a pre-cocked position to the neutral rest position and drives the skin-penetration member in an arcuate path into the surface of the skin thereby creating the wound opening; allowing the first skin-penetration member to obstruct the wound opening when the torsional spring actuator is in the neutral rest position; and transporting body fluid through an inner lumen of the first skin-penetration member.
