LU86009A1 - DEVICE FOR THE AESTHETIC TREATMENT OF THE SKIN - Google Patents

Description

The present invention essentially relates to a device for the aesthetic treatment of the skin.

Various means of treatment or rejuvenation of the skin have already been proposed which allow erasure of wrinkles, wrinkles or the like appearing on the human body, and in particular on the face, from a certain age.

It is thus already known to rejuvenate the skin of the face using cosmetic products, or even using mechanical means such as for example abrasive means or discs or electrodes which are applied to the skin to provide a weak electric shock acting on the muscles and tending to eliminate wrinkles or wrinkles of the epidermis.

However, these various means do not allow a permanent elimination of wrinkles which necessarily reappear more or less long after the treatment. In addition, these means do not allow several areas of the epidermis to be treated at the same time and, in general, are far from providing the efficacy and all the treatment possibilities sought.

The object of the present invention is therefore to remedy all of these drawbacks in particular by proposing a device; perfected which eliminates in a definite way not only wrinkles on the surface of the epidermis, but also cellulite, and which also makes it possible to

treat a large number of epidermal areas with one. 2 nd maximum efficiency.

To this end, the subject of the invention is a device for the aesthetic treatment of the skin and of the type comprising a pulse generator the positive output of which is connected to a means capable of penetrating the skin for treating it and the output of which negative is connected to a means forming a current return electrode, characterized in that the two aforementioned means each consist of a plurality of solid needles associated with the end of a flexible electrically conductive wire and all intended to penetrate the skin to be treated.

According to a preferred embodiment of this device, the same number of solid needles is connected to the positive output of the generator, and to its negative output.

According to another characteristic of the invention, each solid needle is in electrical contact through its heel with the end of the metal conductor forming the core of the aforementioned flexible wire.

According to a preferred embodiment, the heel of each solid needle is plugged into a small socket or the like secured, by welding or crimping, for example, to the end of the aforementioned conductor.

The device of the invention is further characterized by a flexible thermoformable sheath surrounding the end of the flexible wire as well as the heel of the needle to secure the latter of the flexible wire.

It will also be specified here that the aforementioned full needles are supplied with current by means of a timer ensuring the automatic interruption and restoration of the current according to a predetermined frequency / (mined.

This timer is advantageously integrated into the generator which also includes a system allowing the manual or automatic variation of the frequency of the current passing through the needles.

The number of needles connected to each output of the generator can be between 2 and approximately 30 which, in the latter case, makes it possible to treat at the same time a large number of zones of the epidermis.

However, other advantages and characteristics of the invention will appear better in the detailed description which follows and refers to the appended drawings, given solely by way of example, and in which: - Figure 1 is a schematic view of a device or apparatus in accordance with the principles of the invention, and - Figure 2 is an enlarged view in axial section of the end of a flexible wire equipped with a needle.

According to an exemplary embodiment, and with reference to the appended drawings, it can be seen that an apparatus according to the invention essentially comprises a pulse generator 1 which has a positive output 2 and a negative output 3, each output being connected to a plurality of flexible threads 4, the ends of which carry a very fine needle 3.

The flexible wires 4 can be connected to the positive 2 and negative 3 outputs definitively or else via a plug or pin 6.

The number of threads 4 and therefore needles 5 at each outlet is equal to 4, according to the embodiment shown, but this number could be between 2 and 30, without going beyond the ambit of the invention. And preferably 4 the same number of threads and needles are provided on each of the positive 2 and negative 3 outputs.

As can be seen in FIG. 2, each needle 5 is full and in electrical contact through its heel 3a with the end of the metallic conductor 7 forming the core of the flexible wire 4 which, as known per se, comprises a flexible sheath 8 A flexible thermoformable sleeve 9 is mounted on the end of the flexible wire 4, as seen in 10, as well as on the heel 5a of the needle 3, as seen in 11, so as to secure the needle 5 of flexible wire 4.

According to the embodiment shown, the heel 5a of each needle 5 is plugged into a small socket or the like 12 which is secured, by welding or crimping for example, to the end of the conductor 7, as' has been shown schematically in 13.

It is perfectly possible, without departing from the scope of the invention, to make an electrical contact between needle and conductor without using a socket such as 12, for example by simply bringing the heel 5a of needle 5 into contact with the end of the conductor 7, this contact being reliable due to the tightening obtained by the sleeve 9.

The needles 5 are supplied with current by means of a timer integrated into the generator 1 and shown diagrammatically at 14. This timer ensures the automatic interruption and restoration of the current at a predetermined frequency ranging for example from a quarter of a second to a few seconds.

The generator 1 is equipped with an ammeter A and a volmeter V, as well as a general switch 1 ^ allowing the supply or not of the generator 1 by the network. A switch is also provided to interrupt the current passing through the wires 4 and their needles 5. associated. Finally, there is shown schematically at 15 a control making it possible to vary manually or automatically the frequency of the current passing through the needles.

We will now briefly describe the operation of the apparatus which has just been described.

The solid needles φ fine connected to the positive output 2 of the generator are introduced immediately below and substantially parallel to the wrinkles or wrinkling to be treated. The needles 5 connected to the negative output 3 and forming return electrodes are also introduced, immediately below the skin, in appropriate zones, depending on the position of the needles 5 connected to the positive output 2. It should be noted that the needles 5 connected to the negative output „3 of the generator 1 can advantageously also be inserted into wrinkles or folds of the skin.

Then a current is passed through the needles 5, the frequency of which may for example be close to 100 hertz and the intensity of which is of the order of a few micro-amps per needle. Thus, thanks to the timer 14, automatic current pulses will pass through them! needles, and the treatment can be carried out for a time ranging for example from 2 to 4 minutes depending on the size of the wrinkles or wrinkles to be treated. In this regard, it should be noted that with the apparatus of the invention, it is possible at first to treat all the wrinkles having a roughly identical importance, then we will subsequently treat all the wrinkles having an importance lesser.

An apparatus for treating the skin has therefore been produced according to the invention which can be described as universal for treating all skin surface defects, and even for treating cellulite.

In addition the distribution of the current between all the needles which are equal in number to the positive and negative output of the generator will allow a balanced treatment of the treated areas and a particularly effective and lasting flattening of wrinkles.

The invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example.

On the contrary, the invention includes all the technical equivalents of the means described and their combinations if these are carried out according to the spirit.
