Abstract

A skin removal device includes a housing having a handle portion, a drum assembly coupled to the handle portion and including a drum, the drum having an abrasive outer surface configured to abrade skin of a user during rotation of the drum, and an electromechanical drive system disposed at least partially within the housing and configured to rotate the drum. The drum assembly is moveable in a lateral direction relative to the handle portion to enable insertion and removal of the drum assembly.

Claims

1. A skin removal device comprising:

a housing comprising a handle portion;

a drum assembly coupled to the handle portion and comprising a drum having an abrasive outer surface configured to abrade skin of a user during rotation of the drum; and

an electromechanical drive system disposed at least partially within the housing and configured to rotate the drum;

wherein the drum assembly is moveable in a lateral direction relative to the handle portion to enable insertion and removal of the drum assembly.

2. The device of claim 1, wherein an outer surface of the drum comprises an antimicrobial agent.

3. The device of claim 1, wherein the outer surface of the drum comprises an abrasive sheet of material.

4. The device of claim 1, wherein the electromechanical drive system comprises an electric motor coupled to the drum assembly via a plurality of gears.

5. The device of claim 1, further comprising a drive shaft coupled to the electromechanical drive system;

wherein the drum assembly comprises a recess configured to receive at least a portion of the drive shaft and rotatably fix the drive shaft relative to the drum.

6. The device of claim 1, wherein the drive shaft is configured to engage the recess in a friction fit manner.

7. The device of claim 1, further comprising a mounting bracket extending from the housing and configured to support the drum assembly;

and

a biasing member configured to provide a biasing force between the mounting bracket and the drum assembly to bias the drum toward the skin of a user during use of the device.

8. The device of claim 7, wherein the mounting bracket comprises at least one support bracket configured to rotatably support the drum assembly.

9. An exfoliating device comprising:

a housing comprising a handle portion and a mounting bracket extending from the handle portion;

a drum assembly coupled to the handle portion and comprising a cylindrical drum having an abrasive outer surface configured to abrade skin of a user during rotation of the drum, the drum comprising an antimicrobial agent;

a drive system disposed at least partially within the housing and configured to rotate the drum.

10. The device of claim 9, wherein the drum assembly is insertable into and removable from the housing via a lateral side of the handle portion.

11. The device of claim 9, wherein the drive system comprises an electric motor configured to rotate the drum via a drive shaft.

12. The device of claim 11, wherein the drum assembly comprises a recess formed in a first end thereof;

wherein the drive shaft is received within the recess to rotationally fix the drum relative to the drive shaft.

13. The device of claim 9, wherein the mounting bracket comprises a U-shaped support configured to support a second end of the drum assembly.

14. The device of claim 9, further comprising a spring member configured to bias the drum relative to the mounting bracket and toward the skin of a user.

15. The device of claim 9, further comprising a cover configured to engage the handle portion in a snap-fit fashion and substantially cover the drum assembly.

16. A skin removal device, comprising:

a handle portion;

a mounting bracket coupled to the handle portion and having first and second lateral sides; and

a drum assembly rotatably coupled to the mounting bracket, the drum assembly comprising a drum configured to rotate relative to the mounting bracket, the drum comprising an antimicrobial agent;

wherein the drum assembly is insertable and removable in a lateral direction adjacent at least one of the lateral sides of the mounting bracket.

17. The device of claim 16, further comprising a drive mechanism configured to rotate the drum via a drive shaft received in a recess formed in a first end of the drum assembly.

18. The device of claim 16, wherein the mounting bracket comprises a U-shaped support configured to support an end hub coupled to a second end of the drum assembly.

19. The device of claim 16, further comprising a spring configured to bias the drum toward the skin of a user during use.

20. The device of claim 16, wherein the drum assembly comprises a projection configured to extend at least partially through an aperture in one of the lateral sides of the mounting bracket, the projection configured to maintain a position of the drum assembly relative to the mounting bracket.
