Description

Dispositif et traitement par émission de flash lumineux Apparatus and treatment by emitting flash of light
La présente invention concerne les dispositifs de traitement par émission de flash lumineux.The present invention relates to processing devices by light flash emission.
Les publications EP 1 547 538, EP 1 602 340 et EP 1 749 494 de la demanderesse divulguent des dispositifs comportant une pièce à main reliée à un poste de base. La pièce à main comporte au moins une lampe flash et le poste de base comporte le générateur électrique qui fournit l'énergie nécessaire à la lampe flash pour générer les impulsions lumineuses. La pièce à main comporte un guide optique qui reçoit la lumière émise par la lampe flash et qui présente une face de sortie qui peut être appliquée sur la peau pour le traitementPublications EP 1 547 538, EP 1 602 340 and EP 1 749 494 of the applicant disclose devices comprising a handpiece connected to a base station. The handpiece has at least one flashlamp and the base station has the electric generator that provides the energy required for the flashlamp to generate the light pulses. The handpiece has an optical guide that receives the light emitted by the flashlamp and has an exit face that can be applied to the skin for treatment
Dans les pièces à main connues, la face de sortie du guide optique présente une forme généralement rectangulaire qui convient au traitement de larges surfaces mais est inadaptée au traitement de région du corps tels que les oreilles ou le nez.In the known handpieces, the exit face of the optical guide has a generally rectangular shape which is suitable for the treatment of large areas but is unsuited to the treatment of body regions such as the ears or the nose.
La demande EP 0 775 504 divulgue un appareil de traitement par flashs lumineux capable de recevoir des filtres optiques différents. Il existe un besoin pour perfectionner encore les dispositifs de traitement par émission de flash lumineux.EP 0 775 504 discloses a flashlight processing apparatus capable of receiving different optical filters. There is a need to further improve the light flash emission processing devices.
L'invention a ainsi pour objet un dispositif de traitement par émission de flash lumineux, notamment pour l'épilation ou un traitement vasculaire, comportant : une pièce à main, celle-ci comportant une lampe flash et un guide optique recevant la lumière émise par la lampe flash, le guide optique présentant une face de sortie, et un prolongateur optique, muni de moyens de fixation amovible sur la pièce à main, le prolongateur optique recevant la lumière émise par la face de sortie du guide optique, le prolongateur optique présentant une face de sortie de section plus faible que la face de sortie du guide optique.The subject of the invention is thus a light flash emission processing device, in particular for depilation or vascular treatment, comprising: a handpiece, which comprises a flashlamp and an optical guide receiving the light emitted by the flash lamp, the optical guide having an exit face, and an optical extender, provided with removable fixing means on the handpiece, the optical extender receiving the light emitted by the exit face of the optical guide, the optical extension having an exit face of smaller section than the exit face of the optical guide.
Grâce à l'invention, une pièce à main conventionnelle peut être aisément transformée par l'utilisateur en une pièce à main capable de traiter le nez ou les oreilles, notamment pour réaliser une épilation.Thanks to the invention, a conventional handpiece can be easily transformed by the user into a handpiece capable of treating the nose or ears, particularly for performing hair removal.
Dans l'invention, le guide optique sur lequel vient se fixer le prolongateur peut être appliqué sur la peau pour réaliser des traitements. La mise en place du prolongateur peut s'effectuer sans enlèvement du conduit optique.In the invention, the optical guide on which is fixed the extension can be applied to the skin to perform treatments. The extension can be installed without removing the optical conduit.
Le prolongateur optique comporte un conduit optique qui est avantageusement recouvert au moins partiellement par un revêtement opaque, sur sa surface latérale notamment.The optical extender comprises an optical conduit which is advantageously at least partially covered by an opaque coating, especially on its lateral surface.
Ce revêtement opaque est avantageusement réfléchissant, sur sa face interne au moins, afin de réduire les pertes lumineuses lors de la propagation de la lumière dans le conduit optique. Le revêtement opaque est par exemple obtenu par une métallisation du conduit optique, lequel est par exemple un conduit en verre ou en tout autre matériau optiquement transparent convenant à la propagation des impulsions lumineuses.This opaque coating is advantageously reflecting, on its inner face at least, to reduce the light losses during the propagation of light in the optical conduit. The opaque coating is for example obtained by a metallization of the optical conduit, which is for example a conduit of glass or any other optically transparent material suitable for the propagation of light pulses.
La longueur du prolongateur, mesurée entre la face destinée à être appliquée contre le guide optique et celle destinée à être appliquée sur la peau, peut être supérieure à la moitié de celle du guide optique, voire supérieure à la longueur du guide optique. Le guide optique peut être fixé à demeure sur la pièce à main, et le changement du guide optique peut ne se faire qu'en démontant la pièce à main. Le changement de prolongateur ou sa mise en place et son enlèvement peut se faire sans intervention sur le guide optique.The length of the extension, measured between the face intended to be applied against the optical waveguide and that intended to be applied to the skin, may be greater than half that of the optical waveguide, or even greater than the length of the optical waveguide. The optical guide can be fixed on the handpiece, and the change of the optical guide can be done by removing the handpiece. The change of extension or installation and removal can be done without intervention on the optical guide.
La longueur du prolongateur optique est par exemple supérieure ou égale à 45 mm, le prolongateur optique présentant par exemple une forme effilée en direction de son extrémité distale, par exemple une forme pyramidale tronquée ou conique tronquée.The length of the optical extension is for example greater than or equal to 45 mm, the optical extension having for example a tapered shape towards its distal end, for example a truncated truncated pyramidal shape or truncated conical.
La section de la face de sortie du prolongateur optique peut par exemple être inférieure ou égale à 80 mm2, par exemple inférieure ou égale à 70 mm2, mieux à 65 mm2. Le prolongateur optique peut comporter divers moyens de fixation sur la pièce à main, par exemple des moyens de fixation par accrochage mécanique, par exemple au moyen d'une lanière, d'une sangle, de reliefs d'encliquetage, d'une bande à crochets et boucles de type Velcro®. En variante, le prolongateur optique peut être fixé à la pièce à main au moyen d'une pièce de fixation annexe. Les moyens de fixation peuvent encore être des moyens de fixations par aimantation. La face de sortie du guide optique peut se situer en avant de la pièce à main, c'est-à-dire que le reste de la pièce à main se situe derrière la face de sortie lorsque la pièce à main est utilisée.The section of the output face of the optical extender may for example be less than or equal to 80 mm 2 , for example less than or equal to 70 mm 2 , more preferably 65 mm 2 . The optical extender may comprise various fixing means on the handpiece, for example fixing means by mechanical attachment, for example by means of a strap, a strap, snap-on reliefs, a strap Velcro ® hooks and buckles. Alternatively, the optical extender can be attached to the handpiece by means of an attachment piece. The fastening means can still be fastening means by magnetization. The exit face of the optical guide can be located in front of the handpiece, that is to say that the rest of the handpiece is behind the exit face when the handpiece is used.
Le prolongateur optique peut comporter un filtre dichroïque, afin par exemple de corriger le spectre de la lumière pour par exemple traiter moins profondément la peau. Le prolongateur peut par exemple être muni d'un filtre dichroïque bloquant les infrarouges.The optical extender may include a dichroic filter, for example to correct the spectrum of light for example to treat the skin less deeply. The extender may for example be provided with a dichroic filter blocking the infrared.
Le prolongateur peut aussi être dépourvu de filtre optique. Les caractéristiques spectrales de la lumière sortant du guide optique et celles sortant du prolongateur peuvent être sensiblement les mêmes.The extender may also be devoid of optical filter. Characteristics spectral light exiting the optical guide and those leaving the extender may be substantially the same.
Le conduit optique du prolongateur optique peut présenter des faces qui font avec l'axe longitudinal du conduit optique un angle constant entre les faces d'entrée et de sortie.The optical conduit of the optical extender may have faces which make with the longitudinal axis of the optical conduit a constant angle between the input and output faces.
En variante, le conduit optique peut présenter des faces qui font un angle variable avec l'axe longitudinal du conduit optique lorsque l'on se déplace le long de l'axe longitudinal de celui-ci.Alternatively, the optical conduit may have faces that are at a variable angle with the longitudinal axis of the optical conduit as one moves along the longitudinal axis thereof.
L'invention a encore pour objet selon un autre de ses aspects un procédé d'épilation du nez ou des oreilles, dans lequel on fixe de manière amovible, sur une pièce à main comportant une lampe flash et un guide optique, un prolongateur optique tel que défini ci-dessus, et l'on traite le nez ou les oreilles avec la lumière émise par la face de sortie du prolongateur optique.Another subject of the invention, according to another of its aspects, is a method of hair removal of the nose or ears, in which, on a handpiece comprising a flash lamp and an optical guide, an optical extension such as as defined above, and the nose or ears are treated with the light emitted by the output side of the optical extension.
L'invention pourra être mieux comprise à la lecture de la description détaillée qui va suivre, d'exemples de mise en œuvre non limitatifs de celle-ci, et â l'examen du dessin annexé sur lequel : la figure 1 représente en élévation une pièce à main réalisée conformément à un exemple de mise en œuvre de l'invention, la figure 2 représente le prolongateur optique non assemblé sur la pièce à main de la figure 1 , la figure 3 représente le prolongateur optique de la figure 2 assemblé sur la pièce à main de la figure 1 , la figure 4 représente un détail de la figure 3, la figure 5 représente le prolongateur optique prêt à être mis en place sur la pièce à main, la figure 6 est une coupe axiale schématique et partielle de la pièce à main munie du prolongateur optique, la figure 7 est une coupe axiale représentant isolément le conduit optique du prolongateur optique, - la figure 8 représente isolément en perspective le conduit optique du prolongateur optique, la figure 9 est une vue de face selon IX de la figure 7, et la figure 10 est une vue analogue à la figure 6 représentant une variante de réalisation.The invention will be better understood on reading the following detailed description, non-limiting examples of implementation thereof, and on examining the appended drawing, in which: FIG. 1 shows in elevation a hand piece made in accordance with an exemplary implementation of the invention, Figure 2 shows the unassembled optical extension on the handpiece of Figure 1, Figure 3 shows the optical extender of Figure 2 assembled on the Figure 4 shows a detail of Figure 3, Figure 5 shows the optical extension ready to be put in place on the handpiece, Figure 6 is a schematic and partial axial section of the handpiece provided with the optical extension, FIG. 7 is an axial section representing in isolation the optical conduit of the optical extension, FIG. 8 is a perspective view of the optical conduit of the optical extension that, Figure 9 is a front view along IX of Figure 7, and Figure 10 is a view similar to Figure 6 showing an alternative embodiment.
On a représenté à la figure 1 une pièce à main d'un dispositif de traitement par émission de flash lumineux. De tels dispositifs sont décrits dans les demandes de brevet européenFIG. 1 shows a handpiece of a light flash emission processing device. Such devices are described in the European patent applications
EP 1 749 494 A2, et EP 1 602 340 A2 et un exemple de pièce à main est décrit dans le brevet européen EP 1 547 538 B 1 .La pièce à main 10 comporte un boîtier 11 qui forme une poignée et qui supporte un guide optique 12 recevant la lumière émise par une lampe flash située à l'intérieur du boîtier 11, non apparente sur le dessin, pour l'acheminer jusqu'à une face de sortie 13 à appliquer contre la peau pour réaliser par exemple un traitement d'épilation.EP 1 749 494 A2, and EP 1 602 340 A2 and an example of a handpiece is described in European Patent EP 1 547 538 B 1 .The handpiece 10 comprises a housing 11 which forms a handle and which supports a guide optical 12 receiving the light emitted by a flash lamp located inside the housing 11, not shown in the drawing, to route it to an exit face 13 to be applied against the skin to achieve for example a treatment of hair removal.
Le guide optique 12 est monté fixement sur la pièce à main, c'est-à-dire qu'il ne peut être séparé de celle-ci sans avoir à démonter intégralement la pièce à main.The optical guide 12 is fixedly mounted on the handpiece, that is to say that it can not be separated from it without having to completely disassemble the handpiece.
On a représenté à la figure 2 un prolongateur optique 20 destiné à se monter sur la pièce à main 10 afin de réaliser des traitements de régions spécifiques telles que le nez ou les oreilles.There is shown in Figure 2 an optical extender 20 for mounting on the handpiece 10 to perform specific treatments of regions such as the nose or ears.
Ce prolongateur optique 20 comporte un conduit optique 21 que l'on a représenté isolément sur les figures 7 à 9. Le conduit optique 21 présente par exemple une forme allongée selon un axe longitudinal X avec une face d'entrée 22 et une face de sortie 23, de section plus réduite que la face d'entrée 22.This optical extension 20 comprises an optical duct 21 which has been shown separately in FIGS. 7 to 9. The optical duct 21 has, for example, an elongate shape along a longitudinal axis X with an input face 22 and an exit face 23, of smaller section than the input face 22.
Dans l'exemple illustré, le conduit optique 21 présente une forme générale de pyramide tronquée, la face de sortie 23 étant sensiblement perpendiculaire à l'axe X avec des bords arrondis, et de section carrée avec par exemple un côté de 8 mm.In the example illustrated, the optical conduit 21 has a generally truncated pyramid shape, the exit face 23 being substantially perpendicular to the X axis with rounded edges, and of square section with for example a 8 mm side.
Le conduit 21 est réalisé par exemple en verre ou en quartz ou en tout autre matériau transparent, par exemple en matière plastique transparente, et est recouvert sur la majorité de sa longueur, voire la quasi-totalité de sa longueur, par un revêtement opaque 25 qui dans l'exemple considéré est formé par une métallisation du matériau transparent du conduit. Cette métallisation s'étend sur les faces latérales 26 depuis la face d'entrée 22 jusqu'à une distance d de la face de sortie 23, par exemple une distance d inférieure ou égale à 3 mm, par exemple de l'ordre de 2 mm.The duct 21 is made for example of glass or quartz or of any other transparent material, for example transparent plastic material, and is covered over most of its length, or almost all of its length, with an opaque coating 25 which in the example considered is formed by a metallization of the transparent material of the conduit. This metallization extends on the side faces 26 from the input face 22 to a distance d from the output face 23, for example a distance d of less than or equal to 3 mm, for example of the order of 2 mm.
Dans l'exemple considéré, les faces 26 du conduit optique sont planes et font un angle constant avec l'axe X mais il pourrait en être autrement et ces faces 26 pourraient par exemple faire un angle variable avec l'axe X, notamment un angle qui augmente en se rapprochant de la face de sortie.In the example considered, the faces 26 of the optical duct are plane and make a constant angle with the X axis but it could be otherwise and these faces 26 could for example make a variable angle with the X axis, including an angle that increases in approaching the exit face.
Le conduit optique 21 est monté sur un support 30 pour permettre son montage sur l'extrémité du guide optique 12 qui fait saillie hors du boîtier 11. Le support 30 présente une jupe de montage 31 de forme adaptée au guide optique, par exemple une forme sensiblement parallélépipédique dans l'exemple considéré.The optical conduit 21 is mounted on a support 30 to allow its mounting on the end of the optical guide 12 which protrudes from the housing 11. The support 30 has a mounting skirt 31 of shape adapted to the optical guide, for example a shape substantially parallelepipedic in the example.
Le maintien du support 30 sur le guide optique 12 s'effectue dans l'exemple considéré au moyen d'une sangle 40 qui est accrochée sur un crochet 41 du support 30, et peut être engagée à travers l'ouverture 14 de la poignée de la pièce à main. L'autre extrémité de la sangle 40 est munie d'une boucle 43 qui peut être accrochée sur un 25 deuxième crochet 37 du support 30.Maintaining the support 30 on the optical guide 12 is effected in the example in question by means of a strap 40 which is hooked on a hook 41 of the support 30, and can be engaged through the opening 14 of the handle of the handpiece. The other end of the strap 40 is provided with a loop 43 which can be hooked onto a second hook 37 of the support 30.
La sangle 40 est avantageusement réalisée dans un matériau élastiquement déformable, ce qui permet de plaquer le support 30 contre le boîtier 11 comme illustré sur les figures 3 et 4. La fixation du prolongateur optique sur la pièce à main pourrait s'effectuer autrement encore, par exemple par encliquetage de reliefs 50 formés sur le support 30 sur des reliefs complémentaires 52 formés sur le boîtier 11 de la pièce à main, comme illustré sur la figure 10.The strap 40 is advantageously made of an elastically deformable material, which allows to press the support 30 against the housing 11 as shown in Figures 3 and 4. The attachment of the optical extension on the handpiece could be done otherwise still, for example by snapping reliefs 50 formed on the support 30 on complementary reliefs 52 formed on the housing 11 of the handpiece, as shown in Figure 10.
Le prolongateur optique 20 peut comporter un filtre optique 60 AFM de modifier le spectre la lumière émise par la pièce à main, par exemple pour limiter la profondeur de pénétration de la lumière dans la peau.The optical extender 20 may comprise an optical filter 60 AFM to change the light spectrum emitted by the handpiece, for example to limit the depth of penetration of light into the skin.
Le filtre 60 est par exemple un filtre dichroïque formé par une métallisation de la face d'entrée 22 du conduit optique 21. Ce filtre dichroïque est par exemple agencé pour bloquer le rayonnement infrarouge. Le cas échéant, le prolongateur optique peut être muni de moyens permettant de renseigner le dispositif sur sa présence sur la pièce à main.The filter 60 is for example a dichroic filter formed by a metallization of the input face 22 of the optical duct 21. This dichroic filter is for example arranged to block the infrared radiation. If necessary, the optical extender may be provided with means for informing the device on its presence on the handpiece.
Ainsi, le poste de base peut modifier les caractéristiques de la tension appliquée à la lampe flash et par exemple adapter la puissance et/ou la durée des impulsions de façon à tenir compte de la présence du prolongateur optique. La pièce à main peut par exemple comporter un interrupteur qui est actionné par le support du conduit optique 21 lorsque le prolongateur optique est en place sur la pièce à main. L'actionnement de cet interrupteur peut être détecté par le générateur et une action prédéfinie peut alors être effectuée pour modifier les caractéristiques du fonctionnement du générateur.Thus, the base station can modify the characteristics of the voltage applied to the flash lamp and for example adapt the power and / or the duration of the pulses to take into account the presence of the optical extension. The handpiece may for example include a switch that is actuated by the support of the optical conduit 21 when the optical extender is in place on the handpiece. The actuation of this switch can be detected by the generator and a predefined action can then be performed to modify the characteristics of the operation of the generator.
Le prolongateur peut encore comporter des contacts électriques et/ou une mémoire électronique qui renseigne le dispositif sur les caractéristiques du conduit optique afin que l'énergie émise soit adaptée au mieux à la géométrie du conduit optique et au traitement à effectuer.The extender may also include electrical contacts and / or an electronic memory that informs the device on the characteristics of the optical conduit so that the energy emitted is best adapted to the geometry of the optical conduit and the treatment to be performed.
Le caractère amovible du prolongateur optique peut permettre de modifier des pièces à main existantes afin de permettre de traiter des régions du corps autrement inaccessibles à ces pièces à main. De plus, le caractère amovible du prolongateur optique peut faciliter son nettoyage entre les utilisations.The removable nature of the optical extender may allow modification of existing handpieces to allow treatment of body regions otherwise inaccessible to these handpieces. In addition, the removable nature of the optical extender can facilitate its cleaning between uses.
Bien entendu, l'invention n'est pas limitée aux exemples qui viennent d'être décrits.Of course, the invention is not limited to the examples which have just been described.
On peut notamment fixer encore autrement le prolongateur optique sur la pièce à main, par exemple au moyen d'une fixation par aimantation ou en faisant intervenir une 30 bande avec un accrochage mécanique de type Velcro®.Mention may in particular even otherwise fix the optical extension on the handpiece, for example by means of a fastening by magnetization or the interposition of a strip 30 with a mechanical latch of the type Velcro ®.
On peut proposer à l'utilisateur plusieurs prolongateurs optiques ayant des caractéristiques différentes, par exemples quant à la forme du conduit optique des prolongateurs, ou quant à la présence d'un filtre sur le prolongateur pour modifier ses caractéristiques optiques.The user can be offered several optical extensions having different characteristics, for example as to the shape of the optical conduit extensions, or as to the presence of a filter on the extender to change its optical characteristics.
L'expression « comportant un » doit être comprise comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié. The expression "having one" shall be understood as being synonymous with "having at least one", unless the opposite is specified.
