1. An integrated body fluid sampling and analysis device, the device comprising:
- a housing, the housing containing a plurality of body fluid sampling and analysis sites, each of the sites comprising a skin-penetration member in the form of a needle comprising a lumen, and a torsional spring actuator, the torsional spring actuator comprising a first leg, and a second leg moveable relative to the first leg upon release of elastic energy stored in the torsional spring actuator, the skin-penetration member connected to the moveable second leg so as to drive the skin-penetration member into the skin of a user and to act as a guide locating an end of the needle in the body fluid due to the release of the elastic energy and so as to draw the body fluid into the lumen of the needle.

25. An arrangement comprising:
-
a housing containing one or more components configured for at least one of body fluid sampling or analysis; and at least one skin-penetration member comprising a needle, the needle comprising a lumen, and at least one torsional spring actuator, the at least one torsional spring actuator comprising a first leg, and a second leg moveable relative to the first leg upon release of elastic energy stored in the at least one torsional spring actuator, the skin-penetration member connected to the moveable second leg so as to drive the needle into a surface of the skin along a path traveled by the second leg due to the release of the elastic energy and to act as a guide locating an end of the needle in the body fluid so as to draw the body fluid into the lumen of the needle. - View Dependent Claims (27, 28, 29)

26. A method of quantifying the presence or concentration of an analyte contained in a sample of body fluid the method comprising:
-
providing a housing with one or more components configured for at least one of body fluid sampling or analysis, the components comprising at least one skin-penetration member and at least one torsional spring actuator comprising a first leg, and a second leg moveable relative to the first kg; applying the housing to a surface of the skin; and piercing the skin with the at least one skin-penetration members; wherein the at least one skin-penetration member is provided in the form of a needle comprising a lumen, wherein the needle is attached to the second leg, and the needle is driven to pierce the skin by the at least one torsional spring actuator and the needle is guided by the second leg of the at least one torsional spring actuator so as to locate an end of the needle in the body fluid so as to draw the body fluid into the lumen of the needle, and wherein the needle is not retracted prior to quantifying the presence or concentration of an analyte in the sample of body fluid.
