Patent ID: 7846110

Claim:
A self contained disposable testing unit for testing body fluid comprising: a body member, a support member moveable with respect to the body member between a first position and a second position, the support member including a body part receiving surface for receiving a patient's body part, a lancet movable with respect to the support member, the lancet including a first end portion pivotably coupled to the body member for pivotal movement with respect to the body member, and a second end portion having a second end and a base end, the base end being disposed closer to the first end portion than the second end and the second end including a lancet tip capable of piercing a patient's skin to produce fluid flow, wherein during pivotal movement of the lancet, the base end and lancet tip of the second end portion move in an arcuate path and extend along a tangent of an arc scribed by the pivotal movement, wherein the base end follows the lancet tip; a test member capable of interacting with body fluid to aid in determining information about body fluid components; a capillary member capable of directing fluid flow to the test member, a pressure cup for exerting pressure on a body part to foster fluid flow out of a lanced site and into the capillary; and a calibration member capable of containing information for facilitating calibration of the testing unit.
