Abstract

A lancet device is provided with stackable features to carry a plurality of lancets as a single unit. The lancet device includes a lancet body with a sharp tip at one end for drawing a sample of blood. The lancet body has opposing sides with projections on one of the opposing sides and depressions on the other opposing side. The projections and depressions are configured such that projections on one lancet body securely engages into the depressions of an adjacent lancet body providing a stacked formation. As an alternate, the plurality of lancets can be housed in an elongated member so that the plurality of lancets can be transported as a single unit.

Claims

1. A lancet comprising:

a lancet body having opposing ends, a first opposing side, and a second opposing side, said first opposing side and second opposing side defined by surfaces disposed between the opposing ends; and

a sharp tip protruding from one of the opposing ends, wherein the first and second opposing sides of the lancet body are configured to fittingly engage at least one of a first and second opposing side of art adjacent lancet body.

2. The lancet of claim 1 further comprising a cap configured to cover the sharp tip and frangibly attached to the lancet body.

3. The lancet of claim 1, wherein the first opposing side of the lancet has a projection and the second opposing side of the lancet has a depression, the projection and depression configured so that the depression of the lancet body securely engages a projection of the adjacent lancet body.

4. The lancet of claim 3, wherein the projection and depression, are configured to prevent misalignment of the lancet body and the adjacent lancet body when the depression of the lancet body is engaging the projection of the adjacent lancet body.

5. The lancet of claim 3, wherein the lancet body is configured in a cubic formation.

6. The lancet of claim 1 further comprising a third side, wherein the first and second opposing sides and the third side form a U-shaped configuration.

7. The lancet of claim 6, wherein each of the first and second opposing sides, is configured with a channel formed, inside an edge spaced from the third side, the channels of the lancet body engaging with edges of the adjacent lancet body, and wherein the lancet body engaged with the one or more adjacent lancet body forms a stack.

8. The lancet of claim 1, wherein the first and second opposing sides of the lancet body connect to the at least one of the first and second opposing sides of the adjacent lancet body such that force is required to disconnect the lancet body from the adjacent lancet body.

9. A lancet package comprising:

a plurality of lancets each terminating in a sharp tip; and

an elongated member frangibly attached to each of the plurality of lancets and configured to cover the sharp tip of each of the plurality of lancets in the manner of a cap.

10. The lancet package of claim 9, wherein the elongated, member is a sterility strip.

11. The lancet package of claim 10, wherein the strip is configured with a depth sufficient to accommodate the plurality of lancets on opposite sides of the sterility strip.

12. The lancet package of claim 11, wherein the plurality of lancets are configured in an offset arrangement on the opposite sides to the sterility strip.

13. The lancet package of claim 9, wherein the plurality of lancets are configured on the elongated member, to accommodate placement of an open end of a lancing device around one of the plurality of lancets such that the lancet is detached from the elongated member when sufficient force is applied to the lancing device, thereby loading the lancet into the lancing device.

14. The lancet package of claim 9, wherein the elongated member is disposable.

15. A method of loading a lancing device having a skin contact end with a piercing aperture comprising:

providing a lancet package comprised of a plurality of lancets each terminating in a sharp tip and an elongated member frangibly attached to each of the plurality of lancets and configured to cover the sharp;

tip of each of the plurality of lancets in the manner of a cap;

placing the skin contact end of the lancing device over one of the plurality of lancets such the lancet engages a lancet engaging mechanism in the lancing device;

applying a force perpendicular to a central axis of the lancing device sufficient to detach the lancet from the elongated member; and

arming the lancing device by actuating the lancet engaging mechanism to move the lancet so that the sharp tip is within the lancing device.

16. The method of claim 15, wherein the elongated member is a sterility strip.

17. The method of claim 16, wherein the sterility strip is configured with a depth sufficient, to accommodate the plurality of lancets on opposite sides of the sterility strip.

18. The method of claim 17, wherein the plurality of lancets are configured in an offset arrangement on the opposite sides to the sterility strip.
