Abstract

The invention relates to a treatment device designed for sequentially treating the skin in a predetermined area via a movement over this area, comprising

• • a housing
  • a treatment window with a width 1 and included in a plane
  • a guide means adjacent to the treatment window and designed to provide information on the positioning of the device and comprising
  • a body attached to the housing, and
  • at least one roller having a cylindrical body of which the axis of symmetry Δ is parallel to the plane of the treatment window, the roller being mounted on the body and freely rotating relative to the body.

Claims

1. A treatment device for sequentially treating the skin in a predetermined area via a movement over this area, comprising

a housing

a treatment window with a width 1 and included in a plane,

a guide means adjacent to the treatment window and designed to provide information on the positioning of the device and comprising

a body attached to the housing and

at least one roller having a cylindrical body of which the axis of symmetry Δ

is parallel to the plane of the treatment window, the roller being mounted on the body and freely rotating relative to the body,

wherein,

the roller has at least one main area and a secondary area adjacent to and visibly distinct from one another,

and further wherein

the body comprises at least one through-opening (22) in relation to the roller, said opening being dimensioned so as to display in an alternating manner the main area indicating to the user that the device has reached a desired treatment position and at least a portion of the secondary area indicating to the user that the device is beyond a desired treatment position.

2. The device of claim 1, wherein said areas are arranged at least on the bases of the roller.

3. The device of claim 2, wherein the roller has on each of its ends a coded wheel having a tubular body coaxial with the roller and at least one circular face included in the base of the roller, said coded wheel being connected for conjoint rotation with the cylindrical body and removable in translation on the axis Δ

.

4. The device of claim 3, wherein the circular face has in the radial direction three main areas spaced respectively by three secondary areas;

the main area having an angular distribution α

, the secondary area having an angular distribution β

.

5. The device of claim 4, wherein the coded wheel has a circumferential distance of two adjacent areas ranging from 60% to 100% of the width 1.

6. The device of claim 3, wherein the areas are extended from the circular face to the cylindrical body of the roller.

7. The device of claim 1, wherein the guide means has on said body at least one transparent piece covering at least a portion of said through-opening.

8. The device of claim 3, wherein the roller has in its cylindrical body at least one spring means for moving the coded wheels against the body of the accessory.

9. The device of claim 1, wherein the cylindrical surface of the roller intended to come into contact with the skin extends slightly beyond the plane of the treatment window and to the outside.

10. The device of claim 1, wherein the roller has means for gripping the skin on the surface of its cylindrical body.

11. The device of claim 1, wherein said guide means is detachable from the housing.

12. The device of claim 1, further including a light emitter and a control button for triggering said emission through the window.

13. A process for using the treatment device of claim 12, comprising the following steps:

constantly applying the treatment window on the skin and moving the device on the skin, pressing the button when the main area is visible through the through-opening, moving the device forward without pressing the button while the secondary area is visible through the through-opening, and repeating the operation over the entire area of skin to treat.
