Abstract

A blood sampling device designed to divert attention from the pain involved in the puncture of the skin tissue by increasing comfort when lancing the skin by affecting the sensation and perception of pain. Projections on the distal end of a skin pricker contact the skin surface to confuse the nerves in the area of the prick to make the prick less noticeable.

Claims

1. A blood sampling device, comprising:

(a) a body portion having a bore and adapted to house a lancet,

(b) means for forcing the lancet through the bore in the body;

(c) an aperture adapted to receive at least a sharp tip of the lancet; and

(d) projections surrounding the aperture to contact skin tissue.

2. The blood sampling device of claim 1, wherein the projections further comprise a pyramidal shape.

3. The blood sampling device of claim 1, wherein the projections encircle the aperture.

4. The blood sampling device of claim 1, wherein the projections further comprise a rounded tip.

5. The blood sampling device of claim 1, further comprising means for retracting the lancet into the body after the lancet is fired.

6. The blood sampling device of claim 1, further comprising a button for firing the lancet.

7. The blood sampling device of claim 1, further comprising means for adjusting the penetration depth of the lancet.

8. The blood sampling device of claim 1, wherein the means for forcing the lancet through the bore in the body comprises a spring.

9. A lancing device for obtaining a blood sample, comprising:

(a) a body portion having a bore and adapted to house a lancet; and

(b) a nose portion, the nose portion comprising

(1) an aperture adapted to receive at least a sharp tip of the lancet,

(2) a platform surrounding the aperture, and

(2) at least two projections extending from the platform to contact skin tissue.

10. The blood sampling device of claim 9, wherein the projections further comprise a pyramidal shape.

11. The blood sampling device of claim 9, wherein the projections encircle the aperture.

12. The blood sampling device of claim 9, wherein the projections further comprise a rounded tip.

13. The blood sampling device of claim 9, further comprising means for forcing the lancet through the bore in the body.

14. The blood sampling device of claim 9, further comprising means for retracting the lancet into the body after the lancet is fired.

15. A lancing device, comprising:

(a) a body portion having a bore and adapted to house a lancet,

(b) means for forcing the lancet through the bore in the body;

(c) an aperture adapted to receive at least a sharp tip of the lancet;

(d) projections around the aperture to contact skin tissue; and

(e) means for retracting the lancet into the body after firing the device.

16. The blood sampling device of claim 15, wherein the projections further comprise a pyramidal shape.

17. The blood sampling device of claim 15, wherein the projections encircle the aperture.

18. The blood sampling device of claim 15, wherein the projections further comprise a rounded tip.
