Abstract

A massage apparatus comprising a drive unit and a rotatable head coupled to the drive unit for rotation about an axis, and a rotatable head for use with such a massage device. The rotatable head has a skin-engaging end face to contact skin to be massaged. The massage apparatus is configured such that the skin-engaging end face lies in a plane substantially perpendicular to the axis of rotation of the rotatable head. A method of using such a massage device.

Claims

1. A massage device comprising

a drive unit and a rotatable head coupled to the drive unit for rotation about an axis, the rotatable head having a skin-engaging end face to contact skin to be massaged and a cavity in the skin-engaging end face extending into the rotatable head which is sealed closed when the rotatable head is pressed against the skin to be massaged and which is connectable to a source of vacuum to allow air to be evacuated from the cavity, wherein the skin-engaging end face lies in a plane substantially perpendicular to the axis of rotation of the rotatable head, characterized in that the rotatable head is rotatable about its central axis and the inner walls of the cavity comprise an undulating surface such that, in use, skin drawn into the cavity is pushed by the undulations, as the rotatable head rotates.

2. A massage device according to claim 1, wherein the drive unit is configured to oscillate the rotatable head back and forth about its axis of rotation.

4. A massage device according to claim 1, wherein the rotatable head includes a second end face opposite to the skin-engaging end face and, the rotatable head is coupled to the drive unit at the second end face.

6. A massage device according to claim 1, wherein the rotatable head includes a fluid passage extending therethrough and in communication with the cavity to allow air to be evacuated from the cavity when closed by skin being massaged.

7. A massage device according to claim 6, wherein the fluid passage includes a suction pipe mounted to the rotatable head in fluid communication with the cavity, for connection to a vacuum source to evacuate air from the cavity.

9. A massage device according to claim 1, wherein the cavity in the rotatable head is substantially circular with at least one element projecting from the inside circular wall of the cavity providing said undulating surface.

10. A massage device according to claim 9, wherein the at least one element comprises a post received in an aperture in the rotatable head.

11. A massage device according to claim 10, wherein the at least one post is metallic and is connected to a source of Radio Frequency or low impulse current to enable the same to be transmitted to the skin being massaged.

12. A massage device according to claim 10, wherein the fluid passage extends though the at least one post and the at least one post includes a suction hole open to the cavity and in fluid communication with the fluid passage.

13. A massage device according to claim 1, wherein the drive unit is pneumatically powered.

14. A massage device according to claim 1, configured such that the rotational speed of the rotatable head can be controlled within a range of different speeds.

16. A massage device according to claim 1, further comprising at least one LED or laser-emitting means operable to transmit light and/or heat to the skin being massaged.

17. A massage device according to claim 16, wherein the rotatable head comprises a transparent portion between the at least one LED/laser emitting means and the skin-engaging end face to allow light to be transmitted from the at least one LED/laser emitting means to the skin to be massaged.

18. A massage device according to claim 17, wherein the transparent portion is made of Plexiglas.

19. A massage device according to claim 1 further comprising, an outer housing enclosing the drive unit.

20. A massage device according to claim 19, wherein the outer housing includes at least one handle to facilitate manipulation of the massage device.

21. A massage device according to claim 20 further comprising, at least one actuator to control operation of the massage device.

22. A massage device according to claim 21, wherein the at least one actuator is mounted on the at least one handle.

23. A massage device according to claim 13 further comprising, a source of compressed air/gas to power the drive unit.

24. A massage device according to claim 23 further comprising, a control circuit to control operation of the massage device and drive unit thereof.

25. A massage device according to claim 24 further comprising, an electric valve controlled by the control circuit to regulate the supply of compressed air/gas to the drive unit.

26. A massage device according to claim 1, wherein the drive unit is electrically powered, and/or driven by an electric motor.

27. A massage device according to claim 6 further comprising, a suction device connected to the fluid passage to evacuate air from the cavity in the rotatable head.

28. A massage device according to claim 1, wherein the rotatable head is substantially cylindrical.

15. (canceled)

29. A method of massaging a persons skin using a massage device which comprises,

a drive unit and a rotatable head rotatable about a central axis of the head and having a skin-engaging end face to contact the skin to be massaged and a cavity in the skin-engaging end face extending into the rotatable head which lies in a plane substantially perpendicular to the axis of rotation of the rotatable head, the inner walls of the cavity having an undulating surface, the method comprising placing the skin-engaging end face on the skin to be massaged to seal closed the cavity, and

applying a suction force to the cavity to evacuate air therefrom and draw the skin into the cavity, actuating the drive unit to rotate the rotatable head about its central axis which is substantially perpendicular to the surface of the skin being massaged, and the skin drawn into the cavity being pushed by the undulations of the inner walls of the cavity.
