Definitions

• the present invention relates to a device for treating, in particular massage, the connective tissue of the skin of a subject, associated with a source of vacuum.
• the invention relates to devices for treating the
• connective tissue of cutaneous areas of the human body difficult to access because adjacent to other areas of the body and / or having a strong curvature, such as the face, joints, fingers, etc.. In these areas, we generally seek to work the skin by alternating local pinches and relaxation of the connective tissue.
• FR-A-2 752 159 has proposed a massage device, manually operable and allowing, by associating it with a pulsed vacuum source, alternately pinch and release a skin fold.
• this device defines a treatment chamber which is connected to the vacuum source and wherein a partition is, in the upper part, pivotally mounted around a physical axis.
• this partition pinches the skin against a fixed wall of the housing. It is understood that this device is satisfactory only if it remains stationary: as soon as it is moved, the lower edge of the partition rubs, or even gets stuck against the skin of the subject, which makes the device difficult to maneuver reliable and accurate.
• FR-A-2 768 051 proposed to close the open ends of a suction chamber, which extends transversely over any the width of the housing of the device, by rotating discs in sealing engagement against the extreme side walls of the housing.
• the handling of the device against the skin is in principle improved, insofar as each disc can roll on the skin by limiting the friction of the device.
• these discs are necessarily stationary in the direction of the width of the housing, so that they can not approach or listen to one of the other, preventing the skin from being pinched and released to be effectively treated, as explained above.
• FR-A-2 768 051 proposes to add inside the suction chamber transverse rollers, that is to say which extend along the width of the housing, between the side discs, being noted that these rollers are specified as falling in particular EP-AO 224 422. Under these conditions, the rolling lateral supports of the discs are then combined with a massage "palpated-rolled", that is to say, over the entire length of these rollers, the skin is folded in a direction perpendicular to the axis of rotation of the side discs.
• This skin treatment requires very high vacuum levels in the chamber and is incompatible with skin areas with strong curvature and / or for certain types of skin, as explained above.
• the object of the present invention is to overcome the disadvantages mentioned above, by proposing an innovative and beneficial treatment device, which acts by pinching the skin of a subject reliably and efficiently, while being easy and precise to move, especially against areas of delicate skin to be treated, such as the face, joints, scarred areas, etc.
• the subject of the invention is a device for treating, in particular massage, the connective tissue of the skin of a subject, associated with a source of vacuum, as defined in claim 1.
• the or each working element of the device according to the invention combines a double capacity of movements with respect to the same axis of displacement. By being rotatable about itself around this axis, the work element can roll against the skin, which makes its movement particularly easy.
• the device can thus accurately follow elaborated care lines, for example S-shaped traces.
• the work element can pinch the skin in a generally parallel direction. to this axis.
• the translation movements of the working element are controlled by the depression inside the treatment chamber: as this element is translated against the housing wall which delimits, together with the element, the chamber of treatment, the latter is effectively sealed, allowing effective pinching of the skin, without resorting to excessive vacuum levels in the room.
• the device according to the invention is particularly effective and manageable, both for driving the device in rotation on site at 360 °, as for displacements of this device according to rectilinear or curved care lines, for example S-shaped, without differential effect. It is understood that the device according to the invention is particularly well suited to skin areas with a strong curvature, such as the face or joints of the subject, as well as for certain types of fragile skin, for example damaged or scarred skin.
• the device has a reliable structure and can be declined in different sizes, by homothmatie the dimensions of the housing and the work elements. It is thus possible to have a range of devices of different sizes, being noticed that, in the extreme, very small devices can be proposed.
• the treatment chamber does not have to extend from one side of the housing to the other, but on the contrary has a freely chosen volume.
• the structure "housing / work item (s)" is compact and lightweight, which enhances the maneuverability of the device and which allows to apply the work items to areas of the human body difficult to 'access.
• the inertia of this element is negligible vis-à-vis the pressure variations inside the treatment chamber.
• the control of these pressure variations thus directly determines the action on the connective tissue.
• the skin can in particular be alternately pinched and released with a precise frequency, which leads to retightening the connective tissue and stimulating the collagen fibers in a controlled manner. With high frequencies, the skin undergoes a particularly effective dynamic stimulation.
