Abstract

Methods and apparatus for abrading, cleaning, massaging, buffing or otherwise treating the skin, fingernails, toenails or other body surfaces. The basic apparatus comprises a small motor mounted within a hand held housing and a cylindrical member rotatably mounted on the housing. The cylindrical member is rotatably driven by the motor and is covered with a treatment-effecting covering such as abrasive material, cloth, brush bristles, adhesive, massaging projections, etc. The cylindrical member may be placed in contact with the skin, nails or other body surface while rotating, thereby abrading, cleaning, massaging, buffing or otherwise treating the skin, nails or other body surface. In a more advanced embodiment, the device may incorporate a suction apparatus for suctioning away severed particles of skin or other matter. In either embodiment, the device may incorporate a drag for causing the rotation of the cylinder to stop when a predetermined maximum pressure is applied by the cylinder on the underlying body surface, thereby avoiding excessive abrasion or injury to the skin or other body surface being treated.

Claims

1. A apparatus for dermabrasion and skin care in a human or animal subject, said apparatus comprising:

a housing sized and configured to be grasped by a human hand;

a motor disposed within said housing;

at least one cylinder having a body treatment-effecting outer surface, said at least one cylinder being roatably mountable on or in the housing such that its treatment-effecting outer surface may be placed in contact with the skin of the patient; and

,

a drive system for connecting the motor to one of said cylinders when that cylinder is on the housing while its treatment-effecting outer surface is in contact with the skin;

said apparatus being constructed such that said cylinder mounted on the apparatus will automatically stop rotating when the drag on the cylinder exceeds a predetermined maximum amount.

2. Apparatus according to claim 1 wherein the at least one cylinder comprises a variety of cylinders that are interchangeably mountable on the housing, each of said cylinders having a different treatment-effecting outer surface.

3. Apparatus according to claim 2 wherein the cylinders have treatment-effecting surfaces selected from the group consisting of:

mildly abrasive surface for mild dermabrasion;

moderately abrasive surface for moderate dermabrasion;

highly abrasive surface for deep dermabrasion;

a skin cleansing surface;

a cloth surface;

a massaging surface;

a ribbed elastomeric surface; and

,

a brush surface.

4. Apparatus according to claim 1 wherein the motor is battery driven.

5. Apparatus according to claim 1 wherein the drive system comprises a belt drive having a belt that slips when the drag on the cylinder exceeds the predetermined maximum, such slippage of the belt being effective to substantially stop the rotation of the cylinder so long as the drag on the cylinder continues to exceed the predetermined maximum amount.

6. Apparatus according to claim 1 wherein a cavity is formed in the housing and the cylinder is mounted at least partially within the cavity such that only a portion of the cylinder is exposed so as to be placeable in contact with the subject'"'"'s body.

7. Apparatus according to claim 6 wherein cavity is formed such that the ends of the cylinder are substantially shielded by the housing such that the ends of the cylinder can not be placed in contact with the subject'"'"'s body.

8. Apparatus according to claim 6 wherein the cavity is formed and the cylinder is mounted such that only a side surface of the cylinder may be placed in contact with the subject'"'"'s body.

9. Apparatus according to claim 1 wherein the cylinder, when mounted on or in the housing, rotates about an axis of rotation and wherein the treatment-effecting surface of the cylinder is placeable in contact with a body surface that is generally parallel to the axis of rotation about which the cylinder rotates.

10. Apparatus according to claim 6 wherein the cylinder, when mounted within the cavity formed in the housing, rotates about an axis of rotation and wherein the cavity is sized and configured and the cylinder is positioned such that treatment-effecting surface of the cylinder may only be placed in contact with a body surface that is generally parallel to the axis of rotation about which the cylinder rotates.

11. A method for dermabrasion or skin care, said method comprising the steps of:

(A) providing apparatus according to any of the preceding claims 1, 5;

(B) mounting a desired cylinder on the housing;

(C) holding the housing adjacent the subject'"'"'s skin such that the cylinder is in contact with the skin; and

,

(D) energizing the motor so as to cause the cylinder to rotate while in contact with the skin so long as the amount of drag on said cylinder remains below said predetermined maximum amount.

12. A method according to claim 11 wherein the axis about which the cylinder rotates is substantially parallel to the skin surface being contacted by the cylinder during performance of Step D.

13. A method according to claim 11 wherein the method further comprises the step of:

(E) moving the housing such that the rotating cylinder moves over the surface of the skin as it continues to rotate.
