Patent Images
1. A method for actuating a bodily fluid extraction device, comprising:
- providing a penetrating member device that includes at least one penetrating member, a tissue interface surface, and a sample reservoir as a single packaged unit;
pushing down on at least a portion of the tissue interface surface with a body surface; and
applying pressure on at least a portion of the tissue interface surface to push down and electrically actuate a driver to advance the penetrating member to pierce the body surface;
detecting thermally the presence of body fluid from the pierced body surface;
collecting the body fluid in the sample reservoir;
disposing the penetrating member device including the penetrating member, the tissue interface surface, and the sample reservoir as one integrated unit after analyzing the body fluid.

Abstract
A lancet driver is provided wherein the driver exerts a driving force on a lancet during a lancing cycle and is used on a tissue site. The driver comprises of a drive force generator for advancing the lancet and a processor coupled to the drive force generator capable of changing the direction and magnitude of force exerted on the lancet during the lancing cycle. The driver further includes a human interface on the housing providing at least one output for communicating with the patient.
