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 ultrasonic device used in the cosmetic treatment 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. Medical or paramedical devices based on the application of ultrasonic low-frequency fields have been known for many years. Ils sont conçus de manière à recouvrir toute la zone traitée par des transducteurs. They are designed to cover the entire area treated by the 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 restricted to 3 watts / cm2, the ultrasonic power to avoid any skin lesion.

De nombreux appareils comportent un mode séquentiel limitant la possibilité de brulûre de l'épiderme. Many devices have a sequential limiting the possibility of brulûre 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 ultrasound low frequency based on the increase in exocytosis triglycerides during the acoustic phase of depression and in some circumstances, a cavitation effect.

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

Leur fréquence de résonnance varie en fonction des points de soudure nécessaires à l'encapsulage. Their resonance frequency varies with welding 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 operate at a frequency of 30 kHz, the resonant frequencies of each of the transducers will be divided between 29 and 31 KHZ, is an extreme difference of 2000 HZ.

Un transducteur reste en résonnance 100 HZ au dessus et en dessous de sa fréquence de résonnance propre. A transducer rest 100 HZ resonance above and below its natural resonant frequency. 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. To enable each transducer to go into resonance and thus each zone being-subjected to an ultrasonic field the ultrasonic frequency, delivered by the ultrasonic generator varies under the effect of a volubateur, between 29 and 31 KHZ. Ainsi chaque transducteur entrera en résonnance indépendamment les uns des autres, de manière à couvrir la surface maximum. Thus, each transducer will come into resonance independently of each other, so as to cover the maximum area.

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 is the limitation of ultrasonic effects due to safety regulations limiting the power transmitted by a transducer 3 Watt / cm2: The increase of the acoustic intensity in depth, increase the effect of exocytosis and in certain circumstances, such as pre-hydration of the fat cells by hypotonic saline injection, would lead to destructive effect cavitatif fatty tissue 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 selecting two transducers characterized by a very close resonant 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 ultrasound generator so as to deliver sinusoids phase).

La résonnance synchrone et en phase, produit une sommation des effets ultrasonores en profondeur tout en préservant l'épiderme. Synchronous resonance and phase, generates a summation of ultrasonic effects in depth while protecting the epidermis. 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. So are made the conditions for sound intensity increases by summing ultrasonic sine waves and thus exocytosis effects of triglycerides and cell destruction by cavitation when cells are hyperhydratées by hypotonic saline injection.

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 for cold sterilization, necessary when an injection treatment preceded their applications.

L'accent est mis sur des effets localisés au sommet de la masse graisseuse et non sur toute la surface. The emphasis is on local effects on top of the fat and not over the entire surface. Les transducteurs seront positionnés soit côte à côte, soit face à face, de manière à agir sur une zone commune. The transducers are 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 designed device consists of an ultrasonic generator low frequencies, 30 kHz and two transducers whose resonant frequency is 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 ease of selection reasons of the two transducers, the ultrasonic frequency generator is adjustable between 29 kHz and 31 kHz and a volubateur varied 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. For example, when the selection of the transducers results in two frequencies of 30.6 and 30.7 kHz, the ultrasonic generator is set to one of them and volubation be varied around the frequency which has been chosen . Ainsi les effets biologiques et cytolytiques sont maximum et dirigés vers la zone présentant la plus grande épaisseur de graisse. Thus biological and cytolytic effects are up and headed to the area of ​​greatest thickness of fat.
