Abstract

A means and a method is disclosed to diminish or eliminate pain associated with a sharp object penetrating skin, during such procedures as an injection, biopsy, or deriving a blood sample. To this end, repeated tapping, pressing, or rubbing is performed over the skin at or near a site of penetration of the sharp object in conjunction with applying electricity on the skin. The invention discloses a method of using a syringe or a lancet, with enhanced features, to provide local anesthesia at a site of penetration of a sharp object.

Claims

1. A method of diminishing or removing pain of a skin puncture including

a. rubbing side to side repeatedly, on a skin puncture site or a vicinity of said skin puncture site at least before, during, or after the skin puncture and

b. applying electricity by a plurality of electrodes to said skin puncture site or the vicinity of said skin puncture site at least before, during, or after said skin puncture.

2. The method according to claim 1 wherein said rubbing is performed back and forth.

3. The method according to claim 2 wherein said rubbing is performed by a syringe or a lancet that includes said plurality of electrodes.

4. The method according to claim 3 wherein said syringe is an auto-injecting syringe.

5. The method according to claim 1 wherein said rubbing is performed on said skin puncture site.

6. The method according to claim 1 wherein said rubbing is performed on skin in between the plurality of electrodes.

7. The method according to claim 6 wherein the skin puncture site is closer to where said rubbing is performed than to where the plurality of electrodes are placed.

8. The method according to claim 1 wherein said rubbing is performed by said plurality of electrodes.

9. The method according to claim 1 wherein said rubbing is performed by moving on skin on or near said skin puncture site a means with which to rub the skin.

10. The method according to claim 1 wherein said electricity is applied before said skin puncture.

11. The method according to claim 1 wherein said rubbing is performed before said skin puncture.

12. A method of diminishing or removing pain of a skin puncture including

a. rubbing side to side repeatedly, on a skin puncture site or a vicinity of said skin puncture site before the skin puncture and

b. applying electricity by a plurality of electrodes to said skin puncture site or the vicinity of said skin puncture site before and during the skin puncture.

13. A method of diminishing or removing pain of a skin puncture by applying electricity to a first area of skin near a skin puncture site and stopping said applying electricity before the skin puncture, and rubbing repeatedly, side to side, on a second area of the skin at or near the skin puncture site and stopping said rubbing before the skin puncture, wherein the second area of the skin is closer to the skin puncture site than the first area of the skin.

14. The method according to claim 13 wherein said rubbing is performed at least on said skin puncture site.

15. The method according to claim 13 wherein said rubbing is performed by moving on the skin on or near said skin puncture site a means with which to rub the skin.

16. The method according to claim 13 wherein said rubbing is performed by moving a means with which to rub the skin.

17. A method of diminishing or removing pain of a skin puncture by a syringe or a lancet having a first side and a second side and including a needle or a blade disposed on the first side and a plurality of electrodes disposed on the second side, said method including

a. rubbing side to side repeatedly, on a skin puncture site or a vicinity of said skin puncture site before the skin puncture;

b. with the second side facing the skin puncture site and said plurality of electrodes making electric contact with skin, applying electricity by said plurality of electrodes to said skin puncture site or the vicinity of said skin puncture site before the skin puncture,

c. reorienting said syringe or said lancet so that the first side faces the skin puncture site and said electric contact is disrupted; and

d. puncturing the skin puncture site with the needle or the blade.
