Abstract

An endcap for a lancing device includes a contact face with a pattern of ribs or pressure points used to massage skin around a lancet site to force blood for testing from a puncture at the lanced site. The pattern of ribs includes channels defined between the ribs which do not apply pressure on the skin during massaging such that blood flows under the skin below the channels to the puncture. Massaging is performed by applying the contact face under constant pressure to the skin, rocking the contact face, rotating the contact face, or pumping the contact face.

Claims

1. An endcap for a lancing device comprising:

a body,

a contact face on said body

an opening in said contact face, and

a pattern of pressure points on said face, wherein said pressure points comprise a pattern of a plurality of ribs with channels defined between adjacent ribs.

2. The endcap claimed in claim 1 wherein said body is formed of transparent material.

3. The endcap claimed in claim 1 wherein said contact face is concave.

4. The endcap claimed in claim 1 wherein said pressure points are concentric with said opening.

5. The endcap claimed in claim 1 wherein said pressure points extend radially from said opening.

6. An endcap for a lancing device comprising:

a body, said body including a face, an aperture in said face for passage of a lancet, said face being concave, and a rib pattern on said face.

7. The endcap claimed in claim 6 wherein said rib pattern includes a plurality of ribs defining channels between said ribs.

8. The endcap claimed in claim 6 wherein said body is fabricated of transparent material.

9. The endcap claimed in claim 6 wherein said rib pattern includes a plurality of ribs concentric with said aperture.

10. The endcap claimed in claim 6 wherein said rib pattern includes a plurality of ribs extending radially from said aperture.

11. A method of drawing a blood sample for testing, comprising:

providing a lancing device having a lancet and an endcap, said endcap including a skin contacting face with a pattern of pressure points on said face,

placing said face of said endcap onto a selected site,

actuating said lancet to puncture skin at said selected site and,

massaging said site with said skin contacting face on said site to cause blood to flow to said puncture.

12. The method of drawing a blood sample for testing claimed in claim 11 further comprising massaging said site with said skin contacting face prior to actuating said lancet.

13. The method of drawing a blood sample for testing claimed in claim 11 wherein massaging said site comprises alternating turning said endcap clockwise and counterclockwise while maintaining pressure on said selected site.

14. The method of drawing a blood sample for testing claimed in claim 11 wherein said massaging said site comprises rocking said skin contacting face on said site.

15. The method of drawing a blood sample for testing claimed in claim 11 wherein said massaging said site comprises moving said skin contacting face toward and away from said site.

16. The method of drawing a blood sample for testing claimed in claim 11 wherein said massaging said site comprises applying constant pressure on said skin contacting face to move said skin contacting face against said site and apply constant pressure thereon.

17. The method of drawing a blood sample for testing claimed in claim 11 further comprising forming said pattern of pressure points to define channels in said skin contacting face between said pressure points.

18. The method of drawing a blood sample for testing claimed in claim 11 wherein said skin contacting face includes an aperture for passage of said lancet, further comprising beveling said skin contacting face around said aperture thereby providing gradual reduction of pressure toward said aperture as said site is massaged by said skin contacting face.

19. The method of drawing a blood sample for testing claimed in claim 11 wherein said endcap is transparent, further comprising viewing said selected site through said transparent endcap while massaging said site to determine the amount of blood for testing.
