Abstract

The transmitter selects two transducers having close resonant frequencies which does not exceed 200 Hertz so as to produce an input in synchronous resonance with the two transducers. The transducers are sealed by a torique joint permitting cold sterilization when treatment has preceded their application. The in phase resonance produces a summation of the ultrasound effects whilst preserving the epidermis..

Description

DESCRIPTION La présente invention concerne un appareil d'ultrasons basses fréquences mis en oeuvre dans les traitements esthétiques de la cellulite et des masses graisseuses. DESCRIPTION The present invention relates to a low frequency ultrasound device used in the aesthetic treatments of cellulite and fatty masses.

Les dispositifs médicaux ou paramédicaux basés sur l'application de champs ultrasonores basses fréquences sont connus depuis de nombreuses années. Ils sont conçus de manière à recouvrir toute la zone traitée par des transducteurs. Medical or paramedical devices based on the application of low frequency ultrasonic fields have been known for many years. They are designed to cover the entire area treated by transducers.

Pour ce faire les transducteurs sont reliés entre eux sous forme de plaques de six ou neuf transducteurs. To do this, the transducers are interconnected in the form of plates of six or nine transducers.

La législation a limité à 3 watt/cm2, la puissance ultrasonore pour éviter d'éventuelle lésion cutanée. Legislation has limited the ultrasonic power to 3 watt / cm2 to avoid possible skin damage.

De nombreux appareils comportent un mode séquentiel limitant la possibilité de brulûre de l'épiderme. Many devices have a sequential mode limiting the possibility of burning of the epidermis.

Le mode d'action des ultrasons basses fréquences repose sur l'augmentation de l'exocytose des triglycérides pendant la phase de dépression acoustique et dans certaines circonstances, sur un effet de cavitation. The mode of action of low frequency ultrasound is based on the increase in triglyceride exocytosis during the acoustic depression phase and in certain circumstances, on a cavitation effect.

Les transducteurs basses fréquences se composent de céramiques piézo-électrique encapsulées manuellement. The low frequency transducers consist of piezoelectric ceramics encapsulated manually.

Leur fréquence de résonnance varie en fonction des points de soudure nécessaires à l'encapsulage. Their resonant frequency varies according to the solder points necessary for encapsulation.

Ainsi pour un appareil destiné à travailler à une fréquence de 30 KHZ, les fréquences de résonnance de chacun des transducteurs se répartiront entre 29 et 31 KHZ, soit un écart extrême de 2000 HZ. Thus for a device intended to work at a frequency of 30 KHZ, the resonant frequencies of each of the transducers will be distributed between 29 and 31 KHZ, ie an extreme difference of 2000 HZ.

Un transducteur reste en résonnance 100 HZ au dessus et en dessous de sa fréquence de résonnance propre. Pour permettre à chaque transducteur de rentrer en résonnance et donc à chaque zone d'être-soumise à un champ ultrasonore la fréquence ultrasonore, délivrée par le générateur d'ultrasons varie sous l'effet d'un volubateur, entre 29 et 31 KHZ. Ainsi chaque transducteur entrera en résonnance indépendamment les uns des autres, de manière à couvrir la surface maximum. A transducer remains in 100 HZ resonance above and below its own resonant frequency. To allow each transducer to enter into resonance and therefore to each zone of being-subjected to an ultrasonic field, the ultrasonic frequency delivered by the ultrasonic generator varies under the effect of a volubator, between 29 and 31 KHZ. Thus each transducer will enter into resonance independently of each other, so as to cover the maximum surface.

Le problème posé est la limitation des effets ultrasonores due au régles de sécurité limitant la puissance émise par un transducteur à 3 Watt /cm2: L' augmentation de l'intensité acoustique en profondeur, augmenterait l'effet d'exocytose et dans certaines circonstances, telles que l'hyperhydratation préalable des cellules graisseuses par injection de soluté hypotonique, conduirait à un effet cavitatif destructeur tissu graisseux en profondeur. The problem posed is the limitation of the ultrasonic effects due to the safety rules limiting the power emitted by a transducer at 3 Watt / cm2: The increase in the acoustic intensity in depth, would increase the effect of exocytosis and in certain circumstances, such as prior hyperhydration of fat cells by injection of hypotonic solute, would lead to a cavitative effect destroying fatty tissue in depth.

La solution consiste dans la sélection de deux transducteurs caractérisés par une fréquence de résonnance très proche, inférieure à 200 HZ de différence. The solution consists in the selection of two transducers characterized by a very close resonance frequency, less than 200 HZ difference.

Ces deux transducteurs présélectionnés (une fois encapsulés sont reliés à un seul générateur d'ultrasons de manière à délivrer des sinusoïdes en phase). These two preselected transducers (once encapsulated are connected to a single ultrasonic generator so as to deliver sinusoids in phase).

La résonnance synchrone et en phase, produit une sommation des effets ultrasonores en profondeur tout en préservant l'épiderme. Ainsi sont réalisées les conditions d'augmentation d'intensité acoustique par sommation des sinusoïdes ultrasonores et donc les effets d'exocytose des triglycérides et de destruction cellulaire par cavitation lorsque les cellules sont hyperhydratées par injection de soluté hypotonique. The synchronous and phase resonance produces a summation of the ultrasonic effects in depth while preserving the epidermis. Thus, the conditions for increasing acoustic intensity are achieved by summing the ultrasonic sinusoids and therefore the effects of triglyceride exocytosis and cell destruction by cavitation when the cells are hyperhydrated by injection of hypotonic solute.

Les transducteurs sont étanches par un joint torique permettant une stérilisation à froid, nécessaire lorsqu un traitement par injection a précédé leurs applications. The transducers are sealed by an O-ring allowing cold sterilization, necessary when an injection treatment has preceded their applications.

L'accent est mis sur des effets localisés au sommet de la masse graisseuse et non sur toute la surface. Les transducteurs seront positionnés soit côte à côte, soit face à face, de manière à agir sur une zone commune. The emphasis is on effects located at the top of the fat mass and not on the entire surface. The transducers will be positioned either side by side or face to face, so as to act on a common area.

Le nouvel appareil conçu, se compose d'un générateur d'ultrasons basses fréquences, à 30 KHZ et de deux transducteurs dont les fréquence de résonnance sont comprises entre 29,9 et 30,1 KHZ. The new device designed, consists of a generator of low frequency ultrasound, at 30 KHZ and two transducers whose resonance frequencies are between 29.9 and 30.1 KHZ.

En fait, pour des raisons de facilité de sélection des deux transducteurs, la fréquence ultrasonore du générateur est réglable entre 29 KHZ et 31 KHZ et un volubateur fait varier les fréquences autour de la fréquence sélectionnée. In fact, for reasons of ease of selection of the two transducers, the ultrasonic frequency of the generator is adjustable between 29 KHZ and 31 KHZ and a volubator varies the frequencies around the selected frequency.

Par exemple, lorsque la sélection des transducteurs aboutit à deux fréquences de 30,6 et 30,7 KHZ, le générateur d'ultrasons sera réglé sur l'une d'elles et la volubation fera varier les fréquences autour de celle qui aura été choisie. Ainsi les effets biologiques et cytolytiques sont maximum et dirigés vers la zone présentant la plus grande épaisseur de graisse.For example, when the selection of transducers results in two frequencies of 30.6 and 30.7 KHZ, the ultrasound generator will be set to one of them and the volubation will vary the frequencies around that which will have been chosen. . Thus the biological and cytolytic effects are maximum and directed towards the zone presenting the greatest thickness of fat.
