Abstract

Device enabling to clean and preserve contact lenses by the use of appropriate solutions, having a hemispherical bottom (3) by limiting exacting and septic manipulations. It is essentially comprised of a casing (1) having two small containers (2) interconnected at their medial part by a rectilinear narrow channel (6) which is tangent to the container. Each container is closed by screwing a rigid annular capsule (8) whereby a membrane of resilient material (9) is applied to the opening of the container. Once the containers have been filled with the appropriate solution and each contact lens (4) has been positioned in each container and having tightly closed the containers by screwing the capsules (8), the user, by imparting alternatively a digital pressure to the resilient membrane (9), operates the cleaning of the contact lenses by generating a circular liquid flow in each container.

Description

par des solutions appropriées by appropriate solutions
La présente invention a trait au domaine du nettoyage et de l'en¬ tretien de systèmes optiques et concerne tout particulièrement un disposi¬ tif permettant le nettoyage, l'aseptisation et la conservation de lentilles de contacts, notamment du type lentilles souples hydrophiles. Les lentilles de contact souples hydrophiles nécessitent un entre¬ tien quotidien par utilisation d'une solution de nettoyage et/ ou trempage puis rinçage ainsi qu'un traitement hebdomadaire pour l'élimination des dépits de protéines qui s'accumulent quotidiennement.The present invention relates to the field of cleaning and maintenance of optical systems and particularly relates to a device for cleaning, sanitizing and preserving contact lenses, in particular of the hydrophilic soft lens type. Soft hydrophilic contact lenses require daily maintenance by using a cleaning and / or soaking and then rinsing solution as well as a weekly treatment for the elimination of protein deposits which accumulate daily.
Ces, opérations d'entretien, faites en général manuellement, sont astreignantes et augmentent les risques de perte, d'endommagement ou de contamination des lentilles. En outre, elles nécessitent l'utilisation de plusieurs réceptacles tant pour les solutions de nettoyage et de rinçage que pour la conservation ou le stockage des lentilles.These maintenance operations, generally done manually, are demanding and increase the risk of loss, damage or contamination of the lenses. In addition, they require the use of several receptacles both for cleaning and rinsing solutions as for the conservation or storage of the lenses.
Certes, on a déjà préconisé, en substitution aux opérations purement manuelles, l'emploi de deux réceptacles servant de supports aux lentilles qui baignent dans une solution de nettoyage et qui peuvent servir d'agitateurs lorsqu'on tourne le couvercle. Toutefois, un tel dispositif, qui exige un volume relativement important de solution, ne donne pas lieu à un mouvement de brassage des lentilles et à une mise en ëmulsion de la solution de nettoyage. En outre, le positionnement des lentilles dans un tel réceptacle n'est pas aisé et augmente notablement les risques d'endom¬ magement de ces dernières.Admittedly, it has already been recommended, in substitution for purely manual operations, the use of two receptacles serving as supports for the lenses which are immersed in a cleaning solution and which can serve as agitators when the lid is turned. However, such a device, which requires a relatively large volume of solution, does not give rise to a mixing movement of the lenses and to an emulsification of the cleaning solution. In addition, the positioning of the lenses in such a receptacle is not easy and significantly increases the risk of damage to the latter.
L'invention vise à éliminer les inconvéntents ênumérés ci -dessus et a pour but de proposer à l'utilisateur de lentilles souples un moyen supprimant toute manipulation manuelle; et permettant, sans risque pour la lentille, à la fois de réaliser les opérations jusqu'ici fastidieuses de nettoyagertrempage-stërilfsation avec une grande sûreté et une excellente efficacité, tant journellement que pour l'entretien hebdomadaire, ainsi que de jouer le rôle de réceptacle de conservation des lentilles. Pour résoudre ces problèmes, l'invention propose un dispositif de nettoyage et conservation des lentilles souples hydrophiles au moyen de solutions appropriées, caractérisé en ce qu'il comporte un boitier muni de deux réservoirs cylindriques verticaux I fond hémisphérique concave vers le haut, contenant une solution appropriée dans laquelle trempe la lentille et communiquant entre eux par un canal rectiligne et tangent auxdits réservoirs, chacun des réservoirs étant fermé séparément parThe invention aims to eliminate the drawbacks listed above and aims to provide the user of flexible lenses with a means eliminating any manual manipulation; and allowing, without risk for the lens, both to carry out the previously tedious operations of cleaning-soaking-sterilization with great safety and excellent efficiency, both daily and for weekly maintenance, as well as to play the role of receptacle lens storage. To solve these problems, the invention provides a device for cleaning and preserving flexible hydrophilic lenses by means of appropriate solutions, characterized in that it comprises a housing provided with two vertical cylindrical tanks I hemispherical bottom concave upward, containing a suitable solution in which the lens is immersed and communicating with each other by a rectilinear channel and tangent to said reservoirs, each of the reservoirs being closed separately by

Avantageusement, une rainure annula re périphérique est prévue . au niveau de la limite entre la face interne circulaire verticale de cha-, que réservoir et le fond hémisphérique de ce dernier • le canal rectiligne, qui met en communication les deux réservoirs, est situé à hauteur de cette ra nure.Advantageously, a peripheral annular groove is provided. at the limit between the vertical circular internal face of each, that tank and the hemispherical bottom of the latter • the rectilinear channel, which connects the two tanks, is located at the height of this strip.
Conformément à une variante de réalisation, le fond hémisphérique de, chaque réservoir peut comporter une série de rainures radiales dont les extrémités supérieures débouchent perpend culairement dans ladite rainure annulaire périphérique. Ces rainures ou nervures jouent, le rôle de bacs de décantation des poussières él minées par le nettoyage de la lentille et permettent d'éviter â cette dernière de se coller au fond du réservoir. Dans une telle réalisation, où les rainures peuvent être de section carrée à bords légèrement évasés, une rainure verticale est en outre, de préféren¬ ce, prévue sur lia face interne verticale de chaque réservoir, son extrémité inférieure débouchant dans la rainure annulaire périphérique, au droit de l'orifice d'entrée du canal . Cette rainure verticale est destinée à réaliser une prise d'aspiration du liquide et permet d'éviter que la lentille de contact se colle sur l'orifice du canal lors de l'opération de nettoyage.According to an alternative embodiment, the hemispherical bottom, each reservoir may comprise a series of radial grooves whose upper open ends perpend pendicular in said peripheral annular groove. These grooves or ribs play the role of settling tanks for the dust removed by cleaning the lens and make it possible to prevent the latter from sticking to the bottom of the tank. In such an embodiment, where the grooves can be of square section with slightly flared edges, a vertical groove is further, preferably, provided on the vertical internal face of each reservoir, its lower end opening into the peripheral annular groove, to the right of the canal inlet. This vertical groove is intended to make a suction intake for the liquid and makes it possible to prevent the contact lens from sticking to the orifice of the channel during the cleaning operation.
Selon une forme de réalisation préférentielle, la membrane élas¬ tique intégrée à la capsule présente une face supérieure plane, adhérente à sa périphérie à la capsule, et une face inférieure comportant un bourrelet circulaire périphérique assurant le rôle de joint d'étanchëitë lorsque la capsule est vissée sur le réservoir. En outre, la face inférieure de la membrane élastique présente, en dedans du bourrelet, un embout convexe délimitant une chambre à air hémisphérique, communiquant à l'extérieur par un orifice percé au centre dudit embout. Cet embout convexe est destiné éventuellement à servir de support extérieur provisoire à la lentille de contact, la capsule étant retournée à l'extérieur du boîtier. L'orifice central est destiné à faciliter la préhension de la lentille par l'utilisa¬ teur ; en effet, une pression digitale exercée sur la partie extérieure de la membrane a pour résultat de chasser l'air contenu dans la chambre hémisphérique par l'orifice central de l'embout, et permet ainsi le décol¬ lement aisé de la lentille déposée sur ledit embout. L'invention sera maintenant décrite plus en détail par référence aux dessins annexés illustrant des modes d'exécution non limitatffs et qui représentent :According to a preferred embodiment, the elastic membrane integrated into the capsule has a flat upper face, adhering at its periphery to the capsule, and a lower face comprising a circular circular bead ensuring the role of seal when the capsule is screwed onto the tank. In addition, the underside of the elastic membrane has, inside the bead, a convex end-piece defining a hemispherical air chamber , communicating outside by an orifice pierced in the center of said end-piece. This convex tip is optionally intended to serve as a temporary external support for the contact lens, the capsule being returned outside the housing. The central hole is intended to facilitate the gripping of the lens by the user; in fact, a digital pressure exerted on the external part of the membrane has the result of expelling the air contained in the hemispherical chamber through the central orifice of the endpiece, and thus allows easy removal of the lens deposited on said tip. The invention will now be described in more detail with reference to the accompanying drawings illustrating non-limiting embodiments and which represent:

Tel que représenté sur la figure 1, et partiellement sur la figur 2, le dispositif comprend un boîtier 1 dont les dimensions peuvent, par exemple, être de 11 'ordre de six centimètres pour la longueur et deux cen¬ timètres et demi pour la largeur. La face supérieure du boîtier présente deux orifices, par exemple d'environ deux centimètres de diamètre et deux centimètres de profondeur, faisant office de réservoirs 2 surmontés d'un rebord circulaire fileté. Chaque réservoir 2 possède un fond hémisphérique 3 concave vers le haut sur lequel vie<nt'.se positionner la lentille de contact 4. A la limite du fond hémisphérique et de la partie droite du réservoir est prévue une rainure annulaire périphérique 5 et les deux réservoirs communiquent par un canal 6 rectiligne débouchant au niveau de la rainure 5/ et dont on voit en 7 l'orifice d'entrée. Chaque réservoi est fermé par vissage d'une capsule annulaire rigide 8 appliquant une membrane en matière élastique 9 sur l'ouverture du réservoir. Cette embra ne présente un bourrelet circulaire 10 pour assurer une bonne ëtanchêitë.As shown in Figure 1, and partially in Figure 2, the device comprises a housing 1 whose dimensions may, for example, be 11 'of the order of six centimeters for the length and two and a half and a half timers for the width . The upper face of the housing has two orifices, for example about two centimeters in diameter and two centimeters in depth, acting as reservoirs 2 surmounted by a threaded circular rim. Each reservoir 2 has a hemispherical bottom 3 concave upwards on which life <nt '. Position the contact lens 4. At the limit of the hemispherical bottom and the right part of the reservoir is provided a peripheral annular groove 5 and the two tanks communicate by a rectilinear channel 6 opening at the level of the groove 5 / and of which we see at 7 the inlet orifice. Each reservoir is closed by screwing a rigid annular capsule 8 applying an elastic material membrane 9 to the opening of the reservoir. This embra does not have a circular bead 10 to ensure good sealing.
Conformément à la variante illustrée sur les figures 3 à 5, le fond hémisphérique 3 de chaque réservoir est muni d'une série de rainures radiales 11 (par exemple douze sur le dessin) dont l'extrémité supérieure débouche perpendiculairement dans la rainure annulaire périphérique 5. Par ailleurs, la face interne circulaire verticale.de chaque réservoir est munie de la rainure verticale 12 dont l'extrémité inférieure déboucheIn accordance with the variant illustrated in FIGS. 3 to 5, the hemispherical bottom 3 of each reservoir is provided with a series of radial grooves 11 (for example twelve in the drawing), the upper end of which opens perpendicularly into the peripheral annular groove 5 Furthermore, the vertical circular internal face of each reservoir is provided with the vertical groove 12, the lower end of which opens out.

In addition, in a preferred embodiment visible in Figure 3, 'the elastic membrane 9 at its base is of a convex formation con¬ 12 which defines a hemispherical air chamber 13 corn- muniquant with the outside through a perforated hole 14 at center of the convex part 12.
Le fonctionnement du dispositif, dans la forme de réalisation la plus courante de nettoyage- trempage des lentilles, peut se résumer comme suit : L'utilisateur remplit les deux réservoirs jusqu'au niveau sensi¬ blement de la rainure annulaire 5, à l'aide de la solution appropriée telle que : solution de nettoyage;- trempage, eau distillée, sérum physiolo¬ gique ou encore solution dissolvant les protéines. Pour les dimensions indicatives stipulées ci-dessus, le volume de liquide à introduire est de - 1 tordre de cinq millilitres. Puis l'utilisateur introduit ses deux. lentilles dans les deux réservoirs (2, 3) et il ferme ces derniers par vissage des capsules 8. Le boîtier étant fermé, il suffit alors d'imprimer alternative¬ ment une pression digitale sur la membrane élastique 9 de chaque capsule, ce qui a pour effet d'augmenter la pression régnant dans le réservoir sous-jacent et de refouler une partie du liquide contenu dans le preπwer réservoir jusque dans le second réservoir grâce au canal de communication 6. Ainsi le flux linéaire de liquide, engendré dans le canal, se trouve, dès son entrée dans le second réservoir, transformé en flux circulaire parallèle à la paroi circulaire dudit réservoir. Ce flux, en imprimant un mouvement circulaire à la lentille de contact, permet un parfait nettoyage de cette dernière par décollement et élimination centrifuge des particules étrangères de pollutions qui tombent au fond 3 du réservoir ou dans les rainures radiales 11, t l'abri des remous engendrés par e flux de liquide, les particules de pollution ne pouvant ainsi remonter dans le réservoir. L'opération ainsi renouvelée d'un réservoir à l'autre pendant quelques secondes permet de nettoyer des lentilles de contact à l'intérieur même du boîtier, en supprimant ou limitant considérablement les risques de perte ou de contamination de ces dernières. En outre, le boîtier peut bien enten¬ du assurer les fonctions de moyen de trempage et/ou de conserva tion-stocka- ge des lentilles de contact.The operation of the device, in the most common embodiment of cleaning and soaking of the lenses, can be summarized as follows: The user fills the two reservoirs to the level substantially of the annular groove 5, using of the appropriate solution such as: cleaning solution; - soaking, distilled water, physiological serum or solution dissolving proteins. For the indicative dimensions stipulated above, the volume of liquid to be introduced is - 1 twist of five milliliters. Then the user enters his two. lenses in the two reservoirs (2, 3) and it closes the latter by screwing the capsules 8. The housing being closed, it then suffices to alternately print a digital pressure on the elastic membrane 9 of each capsule, which has for the effect of increasing the pressure prevailing in the underlying reservoir and of discharging part of the liquid contained in the preπwer reservoir into the second reservoir thanks to the communication channel 6. Thus the linear flow of liquid, generated in the channel, is, upon entering the second tank, transformed into a circular flow parallel to the circular wall of said tank. This flow, by imparting a circular movement to the contact lens, allows perfect cleaning of the latter by detachment and centrifugal elimination of foreign particles of pollution which fall to the bottom 3 of the reservoir or in the radial grooves 11, t protected from eddies generated by the flow of liquid, the pollution particles not being able to go up in the tank. The operation thus renewed from one reservoir to another for a few seconds makes it possible to clean contact lenses inside the same housing, by eliminating or considerably limiting the risks of loss or of contamination of the latter. In addition, the housing may well enten¬ ensure the functions of soaking means and / or conservation-storage storage of contact lenses.
Il a en outre été constaté que, grâce à la structure du disposi-It has also been found that, thanks to the structure of the device,

Ces phénomènes favorisent encore le nettoyage et/ou la stérilisation des lentilles et donnent des résultats nettement améliorés par rapport à la technique actuelle connue.θM? tif and in particular at the capillary channel 6, there was, during the circulation of a cleaning solution in the tanks as explained above, phenomena of emotion! if fi cation and foaming which, in fact, do not appear during manual agitation, even strong, of a receptacle. containing the same cleaning solution. These phenomena further promote the cleaning and / or sterilization of the lenses and give clearly improved results compared to the current known technique.
En pratique, le boîtier peut être réalisé avantageusement en matière plastique rigide transparent telle que polyméthacrylate de méthyle ou polymères/ copolymères analogues. La membrane peut être exécutée en ëlasto ère caoutchouteux. La rainure annulaire périphérique 5 ainsi que le canal 6 et, s'il y a lieu, les rainures radiales 11, -doivent avoir des diamètres assez réduits, de préférence inférieurs à 0,7 mm afin d'éviter que là lentille de contact déposée dans un réservoir n'ait tendance à être poussée du côté de l'autre réservoir adjacent.In practice, the housing can advantageously be made of transparent rigid plastic material such as polymethyl methacrylate or analogous polymers / copolymers. The membrane can be made in rubbery rubber. The peripheral annular groove 5 as well as the channel 6 and, if necessary, the radial grooves 11, must have fairly small diameters, preferably less than 0.7 mm in order to prevent the deposited contact lens in one tank does tend to be pushed to the side of the other adjacent tank.
Bien entendu, toutes les solutions appropriées de nettoyage, trempage, rinçage, dissolution des protéines peuvent être mises en oeuvre dans le dispositif de l'invention, lequel permet en outre, comme dit ci- dessus, de constituer un moyen de. conservation et stockage des lentilles. Of course, all the appropriate solutions for cleaning, soaking, rinsing, dissolving the proteins can be used in the device of the invention, which also makes it possible, as said above, to constitute a means of. conservation and storage of lenses.
