First Claim
1. An apparatus for lancing skin and collecting a liquid sample comprising:
- a housing sized to be handheld and having an outer periphery;
a rotatable arm rotatably positioned in the housing and having an end movable in an arc from a first predefined position to a second predefined position and then a third predefined position, the end of the rotatable arm being configured to move in a single direction from the first predefined position to the second predefined position to the third predefined position;
a lance for lancing skin, the lance being movable with the end of the rotatable arm, the lance being fully within the outer periphery of the housing when the end of the rotatable arm is in the first predefined position and the lance extends beyond the outer periphery of the housing as the arm is rotating from the first predefined position to the second predefined position to create a lance site in skin of a user, the lance being configured to rotate through an arc to lance the skin as the arm is rotated from the first predefined position to the second predefined position; and
a sample collection area movable with the end of the arm in general fixed relation to the lance as the arm moves between the first, second and third predefined positions, the sample collection area being positioned within an effective range of the lance site to collect the liquid sample from the lance site when the arm is at the third predefined position, the sample collection area being distinct and separate from the lance.

Abstract
An apparatus for lancing skin and collecting a liquid sample. The apparatus having a housing with an outer periphery and a rotatable arm having a lance to puncture the skin. A sample collection area is attached to the arm. The arm of the apparatus rotates from a first position to a second position. As the arm rotates, the lance extends beyond the housing allowing the lance to contact the user'"'"'s skin and create a lance site. As the arm continues to move to the second position, the lance is brought out of contact with the user'"'"'s skin and back within the housing while the collection area is brought into position. When the arm is located in the second position, the collection area is in substantially the same location as the lance site on the user'"'"'s skin.

11. A method of collecting a liquid sample with a hand-held apparatus, the method comprising the acts of:
-
positioning the hand-held apparatus at a site to be lanced, the hand-held apparatus having an outer periphery; rotatably positioning a rotatable arm having a movable end in a housing from a first predefined position to a second predefined position and then to a third predefined position, the end of the arm moving in a single direction and in an arc from the first predefined position to the second predefined position to the third predefined position; rotating a lance in an arc from within the outer periphery of the housing when the end of the rotatable arm is in the first predefined position to an outer periphery of the housing as the rotatable arm is rotating from the first predefined position to the second predefined position to create a lance site in skin of a user; and collecting the liquid sample from the lance site in a sample collection area when the rotatable arm is at the third predefined position, the sample collection area being movable with the end of the arm in general fixed relation to the lance as the arm moves between the first, second and third predefined positions in a single direction, the sample collection area being distinct and separate from the lance. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
