Abstract

The present invention is directed to a dermabrasion device (1) comprising a handle portion (3), a head portion (2) having two arms (4, 5) arranged to receive and hold a drum (6) having an abrasive surface wherein the abrasive surface is in the form of a convex curve such that the diameter at the centre of the drum (6) is greater than the diameter of the ends of the drum (6).

Claims

1. A dermabrasion device comprising:

a handle portion;

a head portion having two arms arranged to receive and hold a drum having an abrasive surface;

wherein the abrasive surface is in the form of a convex curve such that the diameter at the center of the drum is greater than the diameter of the ends of the drum.

2. The dermabrasion device as claimed in claim 1, wherein the surface of the drum is in the form of a parabolic arc.

3. The dermabrasion device as claimed in claim 1, wherein the length of the drum is between 2 and 3 times greater than the diameter of the drum.

4. The dermabrasion device as claimed in claim 3, wherein the length of the drum is 2.5 times greater than the diameter of the drum.

5. The dermabrasion device as claimed in claim 1, wherein the drum is in the shape of a barrel.

6. The dermabrasion device as claimed in claim 5, wherein the drum is in the shape of an elongated barrel.

7. The dermabrasion device as claimed in claim 1 wherein the diameter at the center of the drum is between 10% and 30% larger than the diameter at the ends of the drum.

8. The dermabrasion device as claimed in claim 7, wherein the diameter at the center of the drum is between 15% and 25% larger than the diameter at the ends of the drum.

9. The dermabrasion device as claimed in claim 7, wherein the diameter at the center of the drum is between 20% and 22% larger than the diameter at the ends of the drum.

21. The dermabrasion device as claimed in claim 1, wherein the abrasive surface of the drum is not provided with an antimicrobial agent.

22. The dermabrasion device as claimed in claim 1, wherein the material which forms the abrasive surface is provided with an abrasive material selected from the group consisting of diamond fragments and pumice.

10. A dermabrasion device comprising:

a handle portion;

a head portion having two arms arranged to receive and hold a drum having an abrasive surface;

wherein the abrasive surface is in the form of a concave curve such that the diameter at the center of the drum is smaller than the diameter of the ends of the drum.

11. The dermabrasion device as claimed in claim 10, wherein the surface of the drum is in the form of a parabolic concave arc.

12. The dermabrasion device as claimed in claim 10, wherein the length of the drum is between 2 and 3 times greater than the diameter of the drum.

13. The dermabrasion device as claimed in claim 12, wherein the length of the drum is 2.7-2.8 times greater than the diameter of the drum.

14. The dermabrasion device as claimed in claim 10, wherein the shape of the drum is that of a concave barrel.

15. The dermabrasion device as claimed in claim 10, wherein the diameter at the center of the drum is between 10% and 30% smaller than the diameter at the ends of the drum.

16. The dermabrasion device as claimed in claim 15, wherein the diameter at the center of the drum is between 15% and 25% smaller than the diameter at the ends of the drum.

17. The dermabrasion device as claimed in claim 16, wherein the diameter at the center of the drum is between 17% and 20% smaller than the diameter at the ends of the drum.

18. The dermabrasion device as claimed in claim 10, wherein at least 80% of the surface area of the drum is configured to be used in a dermabrasion process.

19. The dermabrasion device as claimed in claim 18, wherein at least 85% of the surface area of the drum is configured to be used in a dermabrasion process.

20. The dermabrasion device as claimed in claim 18, wherein at least 90% of the surface area of the drum is configured to be used in a dermabrasion process.

25. The dermabrasion device as claimed in claim 10, wherein the abrasive surface of the drum is not provided with an antimicrobial agent.

26. The dermabrasion device as claimed in claim 10, wherein the material which forms the abrasive surface is provided with an abrasive material selected from the group consisting of diamond fragments and pumice.

23. A dermabrasion device comprising:

a handle portion;

a head portion having two arms arranged to receive and hold a drum having a material which provides a massaging effect;

wherein the surface is in the form of a convex curve such that the diameter at the center of the drum is greater than the diameter of the ends of the drum; and

wherein the material which provides the massaging effect is a corrugated rubber.

27. The dermabrasion device as claimed in claim 23, wherein the corrugated rubber is selected from the group consisting of silicone rubber, a thermoplastic elastomer (TPE), and a sponge material.

24. A dermabrasion device comprising:

a handle portion;

a head portion having two arms arranged to receive and hold a drum having a material which provides a massaging effects;

wherein the surface is in the form of a concave curve such that the diameter at the center of the drum is smaller than the diameter of the ends of the drum; and

wherein the material which provides the massaging effect is a corrugated rubber.

28. The dermabrasion device as claimed in claim 24, wherein the corrugated rubber is selected from the group consisting of silicone rubber, a thermoplastic elastomer (TPE), and a sponge material.
