Description

DESCRIPTION DESCRIPTION
TITRE : Dispositif de cultures cellulaires présentant une construction modulaireTITLE: Cell culture device with modular construction
L’invention concerne le domaine des dispositifs de cultures cellulaires et plus précisément une boîte de culture, une plaque de culture, un outil complémentaire, un ensemble et un kit. The invention relates to the field of cell culture devices and more precisely a culture dish, a culture plate, a complementary tool, an assembly and a kit.
Les dispositifs de cultures cellulaires sont conçus pour cultiver des cellules au sein d’au moins un puit de culture qui est utilisé comme une petite éprouvette. Le puit de culture peut être par exemple un puit microfluidique et peut être relié à une puce microfluidique. Cell culture devices are designed to cultivate cells within at least one culture well which is used like a small test tube. The culture well can for example be a microfluidic well and can be connected to a microfluidic chip.
Le puit de culture est réalisé sur une plaque de culture. Ces plaques sont devenues des outils standards dans la recherche et l’analyse clinique des tests de diagnostic des laboratoires. Une plaque de culture est habituellement appelée plaque « microtitre », et peut généralement contenir 6, 24, 96, 384, voire 1536 puits de culture, généralement disposés selon une matrice rectangulaire de format 2 :3, autrement dit dont le rapport largeur/longueur est égale à 2/3. Diverses caractéristiques, notamment les dimensions des puits de culture (diamètre, espacement, profondeur), ainsi que les dimensions et la rigidité de ces plaques ont été normalisées et standardisées par l’American National Standards Institute, à l’initiative de l’association SBS (Society for Biomolecular Screening). Les coordonnées géométriques des centres des puits sont standardisées par style, le style d’une plaque étant déterminé par le nombre de puits de la plaque. Les plaques de culture sont généralement réalisées en Polystyrène, également désigné par l’abréviation PS, qui est un thermoplastique transparent, biocompatible, rigide, peu cher, et facile à mouler. De manière également connue, les plaques de culture, et plus spécifiquement les plaques de culture pour des applications microfluidiques peuvent être réalisées en Polydiméthylsiloxane ou diméthicole, également désigné par l’abréviation PDMS, qui est un élastomère transparent, biocompatible, déformable, très facile à mouler et qui présente des propriétés de perméabilité à l’oxygène intéressantes pour les applications microfluidiques. The culture well is made on a culture plate. These plates have become standard tools in research and clinical analysis of laboratory diagnostic tests. A culture plate is usually called a "microtiter" plate, and can generally contain 6, 24, 96, 384, or even 1536 culture wells, generally arranged in a rectangular matrix of 2:3 format, in other words including the width/length ratio is equal to 2/3. Various characteristics, notably the dimensions of the culture wells (diameter, spacing, depth), as well as the dimensions and rigidity of these plates have been normalized and standardized by the American National Standards Institute, at the initiative of the SBS association. (Society for Biomolecular Screening). The geometric coordinates of the well centers are standardized by style, with the style of a plate being determined by the number of wells in the plate. Culture plates are generally made of Polystyrene, also referred to by the abbreviation PS, which is a transparent, biocompatible, rigid, inexpensive thermoplastic and easy to mold. In a manner also known, the culture plates, and more specifically the culture plates for microfluidic applications can be made of polydimethylsiloxane or dimethicole, also designated by the abbreviation PDMS, which is a transparent, biocompatible, deformable elastomer, very easy to mold and which presents interesting oxygen permeability properties for microfluidic applications.
Il existe des boîtes de culture pour contenir l’au moins une plaque de culture, comme par exemple celle décrite dans le document de brevet EP1932904. Ces boîtes de culture comprennent d’une part des dispositifs de fixation de type ressort pour fixer la plaque de culture à la boîte de culture, et d’autre part un trou de démontage sur une face inférieure permettant de retirer la plaque de culture de la boite de culture. There are culture boxes to contain at least one culture plate, such as for example that described in patent document EP1932904. These culture boxes comprise on the one hand spring-type fixing devices for fixing the culture plate to the culture box, and on the other hand a disassembly hole on a lower face allowing the culture plate to be removed from the culture box. culture box.
Ces dispositifs de fixation ont l’inconvénient de maintenir la plaque de culture en exerçant sur celle-ci une force suivant deux directions perpendiculaires entre elles, et s’étendant dans le plan de la boite de culture. Ainsi, lorsque la plaque de culture est souple, les dispositifs de fixation déforment cette dernière, ce qui empêche notamment la lecture optique des puits de culture. De plus, la plaque de culture est maintenue selon une troisième direction perpendiculaire aux deux premières par des frottements s’exerçant entre la plaque de culture et la boite de culture. Ainsi, le maintien suivant la troisième direction n’est pas parfaitement assuré notamment lors d’une secousse ou d’une chute de la boîte de culture par exemple lors d’un transport. These fixing devices have the disadvantage of holding the culture plate by exerting a force on it in two mutually perpendicular directions, and extending in the plane of the culture box. Thus, when the culture plate is flexible, the fixing devices deform the latter, which prevents in particular the optical reading of the culture wells. In addition, the culture plate is maintained in a third direction perpendicular to the two first by friction occurring between the culture plate and the culture box. Thus, maintenance in the third direction is not perfectly ensured, particularly during a shake or a fall of the culture box, for example during transport.
En outre, le trou de démontage permet d’insérer une tige de démontage sous un coin de la plaque de culture pour soulever celle-ci, ce qui entraine une déformation de cette dernière et un risque de déversement du contenu de la plaque de culture. In addition, the disassembly hole allows a disassembly rod to be inserted under a corner of the culture plate to lift it, which causes deformation of the latter and a risk of spilling the contents of the culture plate.
L’invention a pour but de remédier à tout ou partie des inconvénients précités en proposant, une boîte de culture comprenant au moins un logement configuré pour positionner et maintenir une plaque de culture, ledit logement comprenant : The invention aims to remedy all or part of the aforementioned drawbacks by proposing a culture box comprising at least one housing configured to position and maintain a culture plate, said housing comprising:
- au moins une paroi de maintien configurée pour venir au moins partiellement en contact avec un bord de la plaque de culture, - at least one retaining wall configured to come at least partially into contact with an edge of the culture plate,
- au moins une surface d’appui solidaire de la paroi de maintien, ladite surface d’appui étant configurée pour venir au moins partiellement en contact avec une première surface d’élongation de la plaque de culture, caractérisé en ce que le logement comprend au moins un dispositif de fixation de la plaque de culture, solidaire de la paroi de maintien, ledit au moins un dispositif de fixation comprenant au moins une surface de retenue positionnée en regard de la surface d’appui, ladite surface de retenue délimitant un espace de maintien avec la surface d’appui, ledit espace de maintien ayant une dimension correspondant à au moins une épaisseur de la plaque de culture destinée à venir en regard de l’au moins une surface de retenue. - at least one support surface secured to the holding wall, said support surface being configured to come at least partially into contact with a first elongation surface of the culture plate, characterized in that the housing comprises at at least one device for fixing the culture plate, secured to the retaining wall, said at least one fixing device comprising at least one retaining surface positioned opposite the support surface, said retaining surface delimiting a space of holding with the support surface, said holding space having a dimension corresponding to at least one thickness of the culture plate intended to come opposite the at least one retaining surface.
La paroi de maintien est destinée à entourer en tout ou partie le bord de la plaque de culture. La paroi de maintien entoure au moins en partie le logement. La paroi de maintien est configurée pour permettre l’introduction de la plaque de culture dans le logement en prenant en compte des tolérances de fabrication de la plaque de culture. The retaining wall is intended to surround all or part of the edge of the culture plate. The retaining wall surrounds at least part of the housing. The retaining wall is configured to allow the introduction of the culture plate into the housing while taking into account manufacturing tolerances of the culture plate.
La paroi de maintien permet de positionner dans un plan de maintien la plaque de culture lorsque cette dernière est insérée dans le logement. Préférentiellement, le plan de maintien est un plan dans lequel s’étend la boîte de culture. The holding wall makes it possible to position the culture plate in a holding plane when the latter is inserted into the housing. Preferably, the maintenance plan is a plan in which the culture box extends.
Dans la suite de la description, on entend par des éléments solidaires, que lesdits élément sont monoblocs et unitaires, inamovibles l’un par rapport à l’autre, formés d’un seul tenant, ou qu’il n’y a pas de mouvements relatifs possibles entre eux sans dégradation. In the remainder of the description, the term integral elements means that said elements are in one piece and unitary, immovable relative to each other, formed in one piece, or that there is no possible relative movements between them without degradation.
La surface d’appui est destinée à venir en contact avec tout ou partie de la première surface d’élongation de la plaque de culture. Autrement dit, lorsque la plaque de culture est positionnée dans le logement, la première surface d’élongation est en contact avec la surface d’appui. Préférentiellement, la surface d’appui permet de maintenir la plaque de culture suivant une direction de maintien sensiblement perpendiculaire au plan de maintien. Le dispositif de fixation comprend au moins une surface de retenue qui est positionnée en regard de la surface d’appui. La surface de retenue comprend une première extrémité s’étendant à distance de la paroi de maintien et une deuxième extrémité attachée directement ou par l’intermédiaire d’un élément de liaison à la paroi de maintien. La surface de retenue est séparée de la surface d’appui par l’espace de maintien. Ce dernier présente une dimension permettant une insertion de la plaque de culture entre la surface d’appui et la surface de retenue. Autrement dit, la dimension de l’espace de maintien correspond au minimum à l’épaisseur de la plaque de culture prise au niveau de la surface de retenue lorsque la plaque de culture est positionnée dans le logement. The support surface is intended to come into contact with all or part of the first elongation surface of the culture plate. In other words, when the culture plate is positioned in the housing, the first elongation surface is in contact with the support surface. Preferably, the support surface makes it possible to hold the culture plate in a holding direction substantially perpendicular to the holding plane. The fixing device comprises at least one retaining surface which is positioned opposite the support surface. The retaining surface includes a first end extending away from the retaining wall and a second end attached directly or via a connecting element to the retaining wall. The retaining surface is separated from the supporting surface by the holding space. The latter has a dimension allowing insertion of the culture plate between the support surface and the retaining surface. In other words, the dimension of the holding space corresponds at least to the thickness of the culture plate taken at the level of the retaining surface when the culture plate is positioned in the housing.
Préférentiellement, l’espace de maintien est mesuré selon la direction de maintien. Preferably, the holding space is measured according to the holding direction.
Ainsi, la plaque de culture peut être insérée dans l’espace de maintien sans qu’une force mécanique ou contrainte pouvant entrainer une déformation de la plaque de culture ne s’exerce sur cette dernière après insertion. Autrement dit, lorsque la plaque est dans son logement et quelle est maintenue, aucune force ne s’exerce sur ladite plaque de culture. Thus, the culture plate can be inserted into the holding space without a mechanical force or constraint which could cause deformation of the culture plate being exerted on the latter after insertion. In other words, when the plate is in its housing and is held, no force is exerted on said culture plate.
Lorsque la plaque de culture est introduite dans le logement elle est parfaitement maintenue dans le plan de maintien et selon la direction de maintien de sorte que la plaque de culture est maintenue dans toutes les directions de l’espace quelle que soit l’orientation de la boîte de culture. When the culture plate is introduced into the housing it is perfectly held in the holding plane and in the holding direction so that the culture plate is held in all directions of the space whatever the orientation of the culture box.
L’invention peut également présenter une ou plusieurs des caractéristiques suivantes prises seules ou en combinaison. The invention may also have one or more of the following characteristics taken alone or in combination.
Selon un mode de réalisation, la boîte de culture comprend au moins un logement configuré pour recevoir une plaque de culture pour une application microfluidique. According to one embodiment, the culture dish comprises at least one housing configured to receive a culture plate for a microfluidic application.
Selon un mode de réalisation, la paroi de maintien permet de garantir une adéquation avec un format SBS (Society for Biomolecular Screening). Autrement dit, la paroi de maintien permet de positionner un centre d’un puit de la plaque de culture dans un cercle de 0,7mm de diamètre d’une position théorique. According to one embodiment, the retaining wall makes it possible to guarantee suitability with an SBS (Society for Biomolecular Screening) format. In other words, the retaining wall makes it possible to position a center of a well of the culture plate in a circle of 0.7mm in diameter from a theoretical position.
Selon un mode de réalisation, la surface d’appui forme un bord le long de la paroi de maintien, le bord étant configuré pour ne pas recouvrir en totalité la première surface d’élongation. According to one embodiment, the support surface forms an edge along the retaining wall, the edge being configured so as not to completely cover the first elongation surface.
Selon un mode de réalisation, l’espace de maintien a une dimension correspondant à au moins une épaisseur de la plaque de culture destinée à venir en regard de l’au moins une surface de retenue, augmentée d’un jeu fonctionnel. According to one embodiment, the holding space has a dimension corresponding to at least one thickness of the culture plate intended to come opposite the at least one retaining surface, increased by a functional clearance.
Le jeu fonctionnel est compris dans une première plage de valeur prédéterminée. La première plage de valeur prédéterminée est définie de sorte à prendre en compte des tolérances de fabrication de la plaque de culture. Ainsi, lorsque la plaque de culture est insérée dans l’espace de maintien aucune force mécanique ou contrainte pouvant entrainer une déformation de la plaque de culture ne s’exerce sur cette dernière une fois maintenue. La première plage de valeur prédéterminée peut également définie de sorte à garantir une adéquation avec un format SBS (Society for Biomolecular Screening). Autrement dit, la paroi de maintien permet de positionner le centre d’un puit de la plaque de culture dans un cercle de 0,7mm de diamètre d’une position théorique. The functional clearance is included in a first predetermined value range. The first predetermined value range is defined so as to take into account manufacturing tolerances of the culture plate. Thus, when the culture plate is inserted into the holding space, no mechanical force or stress which could cause deformation of the culture plate is exerted on the latter once held. The first predetermined value range can also be defined so as to guarantee compatibility with an SBS (Society for Biomolecular Screening) format. In other words, the retaining wall makes it possible to position the center of a well of the culture plate in a circle of 0.7mm in diameter from a theoretical position.
Selon un mode de réalisation, l’au moins un dispositif de fixation comprend au moins une surface d’introduction formant un angle d’inclinaison avec la paroi de maintien. According to one embodiment, the at least one fixing device comprises at least one insertion surface forming an angle of inclination with the retaining wall.
La surface d’introduction s’écarte de la paroi de maintien lorsqu’elle s’approche de la surface d’appui. Ledit angle d’inclinaison est compris dans une deuxième plage de valeur prédéterminée comprise entre [0° et 90°], de préférence entre [40° et 85°], et notamment 80°. The insertion surface moves away from the retaining wall as it approaches the support surface. Said inclination angle is included in a second predetermined value range between [0° and 90°], preferably between [40° and 85°], and in particular 80°.
La surface d’introduction facilite l’insertion de la plaque de culture dans le logement et plus particulièrement dans l’espace de maintien en formant une rampe d’insertion. The insertion surface facilitates the insertion of the culture plate into the housing and more particularly into the holding space by forming an insertion ramp.
Selon un mode de réalisation, l’au moins une surface de retenue forme un angle d’inclinaison avec la paroi de maintien. According to one embodiment, the at least one retaining surface forms an angle of inclination with the retaining wall.
La surface de retenue s’écarte de la paroi de maintien lorsqu’elle s’éloigne de la surface d’appui. Ledit angle d’inclinaison est compris dans une troisième plage de valeur prédéterminée comprise entre [0° et 90°], de préférence entre [5° et 85°], et notamment 20°. The retaining surface moves away from the retaining wall as it moves away from the bearing surface. Said inclination angle is included in a third predetermined value range between [0° and 90°], preferably between [5° and 85°], and in particular 20°.
L’inclinaison de la surface de retenue facilite un retrait de la plaque de culture du logement et plus particulièrement de l’espace de maintien. La surface de retenue agit comme une surface d’éjection de la plaque de culture. The inclination of the retaining surface facilitates removal of the culture plate from the housing and more particularly from the holding space. The retaining surface acts as an ejection surface for the culture plate.
Selon un mode de réalisation, l’angle d’inclinaison de la surface de retenue est inférieur à l’angle d’inclinaison de la surface d’introduction. According to one embodiment, the angle of inclination of the retaining surface is less than the angle of inclination of the introduction surface.
Ainsi, le maintien de la plaque de culture est privilégié par rapport au retrait de la plaque de culture. Thus, maintaining the culture plate is favored over removing the culture plate.
Selon un mode de réalisation, l’au moins un dispositif de fixation permet un emboitage élastique de la plaque de culture. According to one embodiment, the at least one fixing device allows elastic nesting of the culture plate.
L'emboîtage élastique est un mode d'assemblage d’un premier élément avec un deuxième élément, dans lequel le premier élément est déformé de manière élastique lors d’une introduction sur le deuxième élément, ou dans lequel le premier et le deuxième éléments sont déformés de manière élastique. Après réalisation de l’emboitage, aucune contrainte ne s’exerce sur le premier élément et sur le deuxième élément qui sont alors au repos. Les éléments ne peuvent être plus être séparés sans exercer une nouvelle contrainte. Dans le cas présent, le premier élément correspond à la boîte de culture tandis que le deuxième élément est la plaque de culture. Selon le matériau de la plaque de culture et une géométrie du dispositif de fixation, l’emboitage élastique se réalise par la déformation de l’un, de l’autre, ou des deux. L’invention porte également sur une plaque de culture destinée à être insérée dans un logement d’une boîte de culture selon l’invention, comprenant au moins un bord configuré pour coopérer avec l’au moins un dispositif de fixation de la boîte de culture. Elastic nesting is a method of assembling a first element with a second element, in which the first element is elastically deformed when introduced onto the second element, or in which the first and second elements are elastically deformed. After completion of the fitting, no stress is exerted on the first element and on the second element which are then at rest. The elements can no longer be separated without exerting a new constraint. In this case, the first element corresponds to the culture dish while the second element is the culture plate. Depending on the material of the culture plate and the geometry of the fixing device, the elastic fitting is achieved by the deformation of one, the other, or both. The invention also relates to a culture plate intended to be inserted into a housing of a culture box according to the invention, comprising at least one edge configured to cooperate with the at least one fixing device of the culture box .
Autrement dit, la plaque de culture comprend un bord pouvant être inséré dans l’espace de maintien. In other words, the culture plate includes an edge that can be inserted into the holding space.
Selon un mode de réalisation, le bord de la plaque de culture a une épaisseur constante. According to one embodiment, the edge of the culture plate has a constant thickness.
Selon un mode de réalisation, le bord de la plaque de culture comprend au moins une encoche destinée à coopérer avec l’au moins un dispositif de fixation de la boîte de culture. According to one embodiment, the edge of the culture plate comprises at least one notch intended to cooperate with the at least one fixing device of the culture box.
Ainsi l’épaisseur de la plaque de culture au niveau du dispositif de fixation est réduite. La plaque de culture présente donc une zone de maintien qui est facilement déformable et qui est positionnée au niveau du dispositif de fixation. Cette zone de maintien déformable permet de faciliter l’introduction et le retrait de la plaque de culture de la boîte de culture. En effet, seul cette zone de maintien sera déformée et non l’ensemble de la plaque de culture. Il n’y pas donc de risque de déversement du contenu de la plaque de culture lors de l’introduction ou du retrait de cette dernière. Thus the thickness of the culture plate at the level of the fixing device is reduced. The culture plate therefore has a holding zone which is easily deformable and which is positioned at the level of the fixing device. This deformable holding zone makes it easier to insert and remove the culture plate from the culture box. In fact, only this holding area will be deformed and not the entire culture plate. There is therefore no risk of spilling the contents of the culture plate when inserting or removing the latter.
Selon un mode de réalisation, la plaque de culture présente une forme non symétrique. According to one embodiment, the culture plate has a non-symmetrical shape.
La forme permet de réaliser un détrompeur permettant de facilement orienter ladite plaque de culture. The shape makes it possible to create a key allowing said culture plate to be easily oriented.
Selon un mode de réalisation, la plaque de culture comprend une deuxième surface d’élongation comprenant au moins un puit de culture. According to one embodiment, the culture plate comprises a second elongation surface comprising at least one culture well.
Selon un mode de réalisation, la plaque de culture comprend une deuxième surface d’élongation, parallèle à la première surface d’élongation. According to one embodiment, the culture plate comprises a second elongation surface, parallel to the first elongation surface.
Selon un mode de réalisation, la première surface d’élongation est espacée de la deuxième surface d’élongation par une épaisseur constante. According to one embodiment, the first elongation surface is spaced from the second elongation surface by a constant thickness.
L’invention porte également sur un module complémentaire destiné à être utilisé avec une boite de culture selon l’invention, comprenant au moins une surface de retrait configurée pour venir au moins partiellement en contact avec la première surface d’élongation de la plaque de culture, et au moins un élément de retrait configuré pour être positionné en regard de l’au moins un dispositif de fixation, et pour exercer une force localisée sur la plaque de culture au niveau du dispositif de fixation. The invention also relates to a complementary module intended to be used with a culture box according to the invention, comprising at least one withdrawal surface configured to come at least partially into contact with the first elongation surface of the culture plate , and at least one withdrawal element configured to be positioned opposite the at least one fixing device, and to exert a localized force on the culture plate at the level of the fixing device.
La surface de retrait a pour objectif de soutenir la plaque de culture lors de son retrait en évitant une déformation de cette dernière aux endroits soutenus. La surface de retrait vient donc au contact de la première surface d’élongation, et plus particulièrement d’une zone centrale de la première surface d’élongation. The purpose of the withdrawal surface is to support the culture plate during its removal by avoiding deformation of the latter in the supported locations. The withdrawal surface therefore comes into contact with the first elongation surface, and more particularly with a central zone of the first elongation surface.
Selon un mode de réalisation, l’au moins une surface de retrait s’étend sensiblement dans un plan de retrait. L’élément de retrait permet d’exercer une force sur la plaque de culture de sorte à réaliser une déformation locale de la plaque de culture, préférentiellement au niveau de la zone de maintien de la plaque de culture, ou, par l’intermédiaire de la plaque de culture, une déformation du dispositif de fixation, afin de retirer la plaque de culture de la boîte de culture sans déformer cette dernière de manière globale. According to one embodiment, the at least one withdrawal surface extends substantially in a withdrawal plane. The withdrawal element makes it possible to exert a force on the culture plate so as to produce a local deformation of the culture plate, preferably at the level of the zone holding the culture plate, or, via the culture plate, a deformation of the fixing device, in order to remove the culture plate from the culture box without deforming the latter overall.
Selon un mode de réalisation, la surface de retrait et l’élément de retrait s’étendent sensiblement dans un même plan. According to one embodiment, the withdrawal surface and the withdrawal element extend substantially in the same plane.
Ainsi, la surface de retrait et l’élément de retrait constitue un support plan à la plaque de culture qui peut être souple, ce qui limite la propension de la plaque de culture à emmagasiner de l'énergie en flexion. En effet, la plaque de culture a tendance à restituer cette énergie en à-coup ou soubresaut, faisant gicler ou se déverser le contenu des puits de culture. Thus, the shrinkage surface and the shrinkage element constitute a plane support for the culture plate which can be flexible, which limits the propensity of the culture plate to store energy in bending. In fact, the culture plate tends to release this energy in jerks or jolts, causing the contents of the culture wells to squirt or spill.
Selon un mode de réalisation, l’élément de retrait a une dimension permettant d’être positionnée en regard de l’encoche du bord de la plaque de culture de sorte à permettre une déformation de la zone de maintien au fond de ladite encoche. According to one embodiment, the removal element has a dimension allowing it to be positioned opposite the notch on the edge of the culture plate so as to allow deformation of the holding zone at the bottom of said notch.
Selon un mode de réalisation, le module complémentaire est physiquement indépendant de la boîte de culture. Autrement dit, il n’y a pas de lien physique entre la boîte de culture et le module complémentaire qui peut donc être éloigné de la boîte de culture d’une distance non prédéterminée. According to one embodiment, the complementary module is physically independent of the culture box. In other words, there is no physical link between the culture box and the complementary module which can therefore be moved away from the culture box by a non-predetermined distance.
Selon un mode de réalisation, le module complémentaire comprend au moins une surface de support configurée pour venir en appui sur la surface d’appui lorsque le module complémentaire est positionné dans l’au moins un logement. According to one embodiment, the complementary module comprises at least one support surface configured to come to rest on the support surface when the complementary module is positioned in the at least one housing.
Ainsi le module complémentaire est configuré pour être positionné dans le logement de la boîte de culture en lieu et place d’une plaque de culture. Thus the complementary module is configured to be positioned in the housing of the culture box instead of a culture plate.
Selon un mode de réalisation, le module complémentaire comprend au moins un bord, configuré pour coopérer avec l’au moins un dispositif de fixation de la boîte de culture. According to one embodiment, the complementary module comprises at least one edge, configured to cooperate with the at least one fixing device of the culture box.
Ainsi le module complémentaire peut être inséré dans l’espace de maintien du dispositif de fixation. Thus the complementary module can be inserted into the holding space of the fixing device.
Selon un mode de réalisation, le bord du module complémentaire a une épaisseur sensiblement constante. According to one embodiment, the edge of the complementary module has a substantially constant thickness.
Selon un mode de réalisation, le bord du module complémentaire comprend au moins une zone élastique destinée à coopérer avec l’au moins un dispositif de fixation de la boîte de culture.According to one embodiment, the edge of the complementary module comprises at least one elastic zone intended to cooperate with the at least one fixing device of the culture box.
Selon un mode de réalisation, le bord du module complémentaire comprend au moins une encoche destinée à coopérer avec l’au moins un dispositif de fixation de la boîte de culture.According to one embodiment, the edge of the complementary module comprises at least one notch intended to cooperate with the at least one fixing device of the culture box.
Ainsi l’épaisseur du module complémentaire au niveau du dispositif de fixation est réduite afin de faciliter l’introduction et le retrait du module complémentaire de la boîte de culture. Thus the thickness of the complementary module at the level of the fixing device is reduced in order to facilitate the introduction and removal of the complementary module from the culture box.

La boîte de culture 1 selon l’invention est représentée sur les figures 1 à 4. Elle comprend une plaque de fond 11 , un élément intermédiaire 12 et un couvercle 13. The culture box 1 according to the invention is shown in Figures 1 to 4. It comprises a bottom plate 11, an intermediate element 12 and a cover 13.
La plaque de fond 11 s’étend sensiblement dans un plan. La plaque de fond 11 a une forme non symétrique, c'est-à-dire qu’elle a une forme sensiblement rectangulaire avec trois angles arrondis et un angle droit. Sur au moins un bord, elle comprend des premiers moyens d’attache 111. La plaque de fond 11 comprend également au moins un épaulement de centrage 112.The bottom plate 11 extends substantially in a plane. The bottom plate 11 has a non-symmetrical shape, that is to say it has a substantially rectangular shape with three rounded corners and one right angle. On at least one edge, it includes first attachment means 111. The bottom plate 11 also includes at least one centering shoulder 112.
Le couvercle 13 a une forme sensiblement identique à une partie supérieure de l’élément intermédiaire 12, dans le cas présent, le couvercle 13 a une forme non symétrique, c'est-à-dire qu’il a une forme sensiblement rectangulaire avec trois angles arrondis et un angle droit, de sorte à pouvoir être emboîté sur l’élément intermédiaire 12. Le couvercle 13 comprend également au moins un épaulement de centrage 131 sur une face intérieure et/ou sur une face extérieure pour permettre un empilement de plusieurs boîtes de culture 1. The cover 13 has a shape substantially identical to an upper part of the intermediate element 12, in the present case, the cover 13 has a non-symmetrical shape, that is to say it has a substantially rectangular shape with three rounded corners and a right angle, so that it can be fitted onto the intermediate element 12. The cover 13 also comprises at least one centering shoulder 131 on an interior face and/or on an exterior face to allow several boxes to be stacked of culture 1.
L’élément intermédiaire 12 a une forme sensiblement identique à la plaque de fond 1 1 dans une partie inférieure et au couvercle 13 dans la partie supérieure. Dans le cas présent, l’élément intermédiaire 12 a une forme non symétrique, c'est-à-dire qu’il a une forme sensiblement rectangulaire avec trois angles arrondis et un angle droit. Sur au moins un bord, il comprend des troisièmes moyens d’attache 121. The intermediate element 12 has a shape substantially identical to the bottom plate 11 in a lower part and to the cover 13 in the upper part. In the present case, the intermediate element 12 has a non-symmetrical shape, that is to say it has a substantially rectangular shape with three rounded corners and one right angle. On at least one edge, it includes third attachment means 121.
L’élément intermédiaire 12 comprend au moins un logement 2 permettant de positionner et de maintenir une plaque de culture 4 ou des modules complémentaires 3. The intermediate element 12 comprises at least one housing 2 making it possible to position and maintain a culture plate 4 or additional modules 3.
Le logement 2 comprend une paroi de maintien 21 configurée pour venir en contact avec un bord 41 de la plaque de culture 4. La paroi de maintien 21 est destinée à entourer en tout ou partie le bord 41 de la plaque de culture 4. La paroi de maintien 21 entoure le logement 2. The housing 2 comprises a retaining wall 21 configured to come into contact with an edge 41 of the culture plate 4. The retaining wall 21 is intended to surround all or part of the edge 41 of the culture plate 4. The wall holding 21 surrounds the housing 2.
La paroi de maintien 21 est configurée pour permettre l’introduction de la plaque de culture 4 dans le logement 2 en prenant en compte des tolérances de fabrication de la plaque de culture 4. La paroi de maintien 21 permet de positionner dans un plan de maintien la plaque de culture 4 lorsque cette dernière est insérée dans le logement 2. Préférentiellement, le plan de maintien est un plan dans lequel s’étend la boîte de culture 1. The holding wall 21 is configured to allow the introduction of the culture plate 4 into the housing 2 while taking into account the manufacturing tolerances of the culture plate 4. The holding wall 21 makes it possible to position in a holding plane the culture plate 4 when the latter is inserted into the housing 2. Preferably, the holding plane is a plane in which the culture box 1 extends.
Selon un mode de réalisation, la paroi de maintien 21 permet de garantir une adéquation avec un format SBS (Society for Biomolecular Screening). Autrement dit, la paroi de maintien 21 permet de positionner un centre d’un puit 42 de la plaque de culture 4 dans un cercle de 0,7mm de diamètre d’une position théorique. According to one embodiment, the retaining wall 21 makes it possible to guarantee suitability with an SBS (Society for Biomolecular Screening) format. In other words, the retaining wall 21 makes it possible to position a center of a well 42 of the culture plate 4 in a circle of 0.7mm in diameter from a theoretical position.
Le logement 2 comprend également une surface d’appui 22 solidaire de la paroi de maintien 21 , ladite surface d’appui 22 étant configurée pour venir partiellement en contact avec une première surface d’élongation 43 de la plaque de culture 4. Autrement dit, lorsque la plaque de culture 4 est positionnée dans le logement 2, la première surface d’élongation 43 est en contact avec la surface d’appui 22. Préférentiellement, la surface d’appui 22 permet de maintenir la plaque de culture 4 suivant une direction de maintien sensiblement perpendiculaire au plan de maintien.The housing 2 also comprises a support surface 22 secured to the retaining wall 21, said support surface 22 being configured to partially come into contact with a first elongation surface 43 of the culture plate 4. In other words, when the culture plate 4 is positioned in the housing 2, the first elongation surface 43 is in contact with the support surface 22. Preferably, the support surface 22 makes it possible to maintain the culture plate 4 in one direction holding device substantially perpendicular to the holding plane.
Selon un mode de réalisation, la surface d’appui 22 forme un bord le long de la paroi de maintien 21 , le bord étant configuré pour ne pas recouvrir en totalité la première surface d’élongation 43. Le logement 2 comprend en outre au moins un dispositif de fixation 23 de la plaque de culture 4. Chaque dispositif de fixation 23 est solidaire de la paroi de maintien 21. According to one embodiment, the support surface 22 forms an edge along the retaining wall 21, the edge being configured so as not to completely cover the first elongation surface 43. The housing 2 further comprises at least a fixing device 23 for the culture plate 4. Each fixing device 23 is integral with the retaining wall 21.
Le dispositif de fixation 23 comprend, comme illustrée en figure 12, une surface de retenue 232 positionnée en regard de la surface d’appui 22. La surface de retenue 232 comprend une première extrémité s’étendant à distance de la paroi de maintien 21 et une deuxième extrémité attachée directement ou par l’intermédiaire d’un élément de liaison à la paroi de maintien 21 .The fixing device 23 comprises, as illustrated in Figure 12, a retaining surface 232 positioned opposite the bearing surface 22. The retaining surface 232 comprises a first end extending at a distance from the retaining wall 21 and a second end attached directly or via a connecting element to the retaining wall 21.
Selon un mode de réalisation, l’au moins une surface de retenue 232 forme un angle d’inclinaison avec la paroi de maintien 21. Plus précisément, la surface de retenue 232 s’écarte de la paroi de maintien 21 lorsqu’elle s’éloigne de la surface d’appui 22. Ledit angle d’inclinaison est compris dans une troisième plage de valeur prédéterminée comprise entre [0° et 90°], de préférence entre [5° et 85°], et notamment 20°. According to one embodiment, the at least one retaining surface 232 forms an angle of inclination with the retaining wall 21. More precisely, the retaining surface 232 moves away from the retaining wall 21 when it moves away from the support surface 22. Said angle of inclination is included in a third predetermined value range between [0° and 90°], preferably between [5° and 85°], and in particular 20°.
L’inclinaison de la surface de retenue 232 facilite un retrait de la plaque de culture 4 du logement 2. La surface de retenue 232 agit comme une surface d’éjection de la plaque de culture 4.The inclination of the retaining surface 232 facilitates removal of the culture plate 4 from the housing 2. The retaining surface 232 acts as an ejection surface of the culture plate 4.
Un espace de maintien est délimité entre la surface de retenue 232 et la surface d’appui 22. L’espace de maintien a une dimension correspondant à au moins une épaisseur de la plaque de culture 4 destinée à venir en regard de l’au moins une surface de retenue 232. Préférentiellement, l’espace de maintien est mesuré selon la direction de maintien. A holding space is delimited between the retaining surface 232 and the support surface 22. The holding space has a dimension corresponding to at least one thickness of the culture plate 4 intended to come opposite the at least a retaining surface 232. Preferably, the holding space is measured according to the holding direction.
L’espace de maintien présente une dimension permettant une insertion de la plaque de culture 4 entre la surface d’appui 22 et la surface de retenue 232. Autrement dit, la dimension de l’espace de maintien correspond au minimum à l’épaisseur de la plaque de culture 4 prise au niveau de la surface de retenue 232 lorsque la plaque de culture 4 est positionnée dans le logement 2.The holding space has a dimension allowing insertion of the culture plate 4 between the support surface 22 and the retaining surface 232. In other words, the dimension of the holding space corresponds at least to the thickness of the culture plate 4 taken at the level of the retaining surface 232 when the culture plate 4 is positioned in the housing 2.
L’espace de maintien peut être augmenté d’un jeu fonctionnel. Le jeu fonctionnel est compris dans une première plage de valeur prédéterminée. La première plage de valeur prédéterminée est définie de sorte à prendre en compte des tolérances de fabrication de la plaque de culture 4. Ainsi, lorsque la plaque de culture 4 est insérée dans l’espace de maintien aucune force mécanique ou contrainte pouvant entrainer une déformation de la plaque de culture 4 ne s’exerce sur cette dernière. The holding space can be increased with functional clearance. The functional clearance is included in a first predetermined value range. The first predetermined value range is defined so as to take into account manufacturing tolerances of the culture plate 4. Thus, when the culture plate 4 is inserted into the holding space no force mechanical or constraint which could lead to deformation of the culture plate 4 is exerted on the latter.
La première plage de valeur prédéterminée peut également être définie de sorte à garantir une adéquation avec un format SBS (Society for Biomolecular Screening). Autrement dit, la paroi de maintien 21 permet de positionner le centre d’un puit 42 de la plaque de culture 4 dans un cercle de 0,7mm de diamètre d’une position théorique. The first predetermined value range can also be defined to ensure suitability for an SBS (Society for Biomolecular Screening) format. In other words, the retaining wall 21 makes it possible to position the center of a well 42 of the culture plate 4 in a circle of 0.7mm in diameter from a theoretical position.
Selon un mode de réalisation, l’au moins un dispositif de fixation 23 comprend également au moins une surface d’introduction 231 , comme illustrée en figure 12, qui forme un angle d’inclinaison avec la paroi de maintien 21. La surface d’introduction 231 s’écarte de la paroi de maintien 21 lorsqu’elle s’approche de la surface d’appui 22. Ledit angle d’inclinaison est compris dans une deuxième plage de valeur prédéterminée comprise entre [0° et 90°], de préférence entre [40° et 85°], et notamment 80°. According to one embodiment, the at least one fixing device 23 also comprises at least one insertion surface 231, as illustrated in Figure 12, which forms an angle of inclination with the retaining wall 21. The surface of introduction 231 deviates from the retaining wall 21 when it approaches the support surface 22. Said angle of inclination is included in a second predetermined value range between [0° and 90°], of preferably between [40° and 85°], and in particular 80°.
La surface d’introduction 231 facilite l’insertion de la plaque de culture 4 dans le logement 2 et plus particulièrement dans l’espace de maintien en formant une rampe d’insertion. The insertion surface 231 facilitates the insertion of the culture plate 4 into the housing 2 and more particularly into the holding space by forming an insertion ramp.
Le dispositif de fixation 23 permet un emboitage élastique de la plaque de culture 4 dans le logement 2. The fixing device 23 allows elastic nesting of the culture plate 4 in the housing 2.
L'emboîtage élastique est un mode d'assemblage de la plaque de culture 4 avec l’élément intermédiaire 12, dans lequel selon le matériau de la plaque de culture 4 et une géométrie du dispositif de fixation 23, le dispositif de fixation 23 ou la plaque de culture 4 sont déformés de manière élastique lors d’une introduction de l’un dans l’autre, ou dans lequel le dispositif de fixation 23 et la plaque de culture 4 sont déformés de manière élastique. Après réalisation de l’emboitage, aucune contrainte ne s’exerce ni sur le dispositif de fixation 23, ni sur la plaque de culture 4 qui sont alors au repos. Le dispositif de fixation 23 et la plaque de culture 4 ne peuvent plus être séparés sans exercer une nouvelle contrainte. Elastic nesting is a method of assembling the culture plate 4 with the intermediate element 12, in which depending on the material of the culture plate 4 and a geometry of the fixing device 23, the fixing device 23 or the culture plate 4 are elastically deformed when one is introduced into the other, or in which the fixing device 23 and the culture plate 4 are elastically deformed. After completion of the fitting, no stress is exerted either on the fixing device 23, or on the culture plate 4 which are then at rest. The fixing device 23 and the culture plate 4 can no longer be separated without exerting new stress.
Ainsi, la plaque de culture 4 peut être insérée dans l’espace de maintien sans qu’une force mécanique ou contrainte pouvant entrainer une déformation de la plaque de culture 4 ne s’exerce sur cette dernière après insertion, c'est-à-dire une fois en place. Lorsque la plaque de culture 4 est introduite dans le logement 2 elle est parfaitement maintenue dans le plan de maintien et selon la direction de maintien de sorte que la plaque de culture 4 est maintenue dans toutes les directions de l’espace quelle que soit l’orientation de la boîte de culture 1. Thus, the culture plate 4 can be inserted into the holding space without a mechanical force or constraint which could cause deformation of the culture plate 4 being exerted on the latter after insertion, i.e. say once in place. When the culture plate 4 is introduced into the housing 2 it is perfectly held in the holding plane and in the holding direction so that the culture plate 4 is held in all directions of the space whatever the orientation of the culture box 1.
L’élément intermédiaire 12 comprend également un moyen humidificateur d’air 122. Le moyen humidificateur d’air 122 entoure de manière continue un bord de l’élément intermédiaire 12 de sorte qu’un liquide peut se répartir sur l’ensemble du bord de l’élément intermédiaire 12. Le moyen humidificateur d’air 122 comprend des éléments de méandre permettant notamment d’amortir et de contrôler un mouvement du fluide. La plaque de fond 11 , le couvercle 13 et l’élément intermédiaire 12 sont configurés pour être emboîtée ensemble de manière séparables. Plus précisément, et comme illustré en figures 1 à 4, les premiers moyens d’attache 111 de la plaque de fond 11 coopèrent avec les troisièmes moyens d’attache 121 de l’élément intermédiaire 12, tandis que le couvercle 13 est emboîté sans maintien spécifique sur l’élément intermédiaire 12.. Ainsi, la plaque de fond 11 et le couvercle 13 peuvent être assemblés sur l’élément intermédiaire 12. The intermediate element 12 also comprises an air humidifying means 122. The air humidifying means 122 continuously surrounds an edge of the intermediate element 12 so that a liquid can be distributed over the entire edge of the the intermediate element 12. The air humidifier means 122 comprises meander elements making it possible in particular to dampen and control a movement of the fluid. The bottom plate 11, the cover 13 and the intermediate element 12 are configured to be fitted together in a separable manner. More precisely, and as illustrated in Figures 1 to 4, the first attachment means 111 of the bottom plate 11 cooperate with the third attachment means 121 of the intermediate element 12, while the cover 13 is fitted without retaining specific on the intermediate element 12. Thus, the bottom plate 11 and the cover 13 can be assembled on the intermediate element 12.
En outre, l’au moins un épaulement de centrage 112 de la plaque de fond 11 permet de positionner facilement l’élément intermédiaire 12 sur cette dernière afin de réaliser facilement la fixation de l’élément intermédiaire 12 sur la plaque de fond 11 . In addition, the at least one centering shoulder 112 of the bottom plate 11 makes it possible to easily position the intermediate element 12 on the latter in order to easily attach the intermediate element 12 to the bottom plate 11.
L’au moins un épaulement de centrage de la face extérieure 131 du couvercle 13 permet d’empiler facilement plusieurs boîtes de culture 1 l’une au-dessus de l’autre. Plus précisément, l’épaulement de centrage 131 peut coopérer avec la plaque de fond 11 ou avec l’élément intermédiaire 12. Ainsi, il est possible d’empiler plusieurs boîtes de culture comprenant la plaque de fond 11 , ou de manière alternative sans la plaque de fond 1 1 . The at least one centering shoulder of the exterior face 131 of the cover 13 makes it possible to easily stack several culture boxes 1 one above the other. More precisely, the centering shoulder 131 can cooperate with the bottom plate 11 or with the intermediate element 12. Thus, it is possible to stack several culture boxes comprising the bottom plate 11, or alternatively without the bottom plate 1 1 .
La boîte de culture 1 peut être utilisée avec ou sans la plaque de fond 11 . La plaque de fond 11 permet de protéger, notamment lors d’une manipulation, l’au moins une plaque de culture 4 positionnée dans le logement 2 de l’élément intermédiaire 12. En outre, la plaque de fond 11 présente des caractéristiques d’épaisseur et de transparence permettant une imagerie microscope à moyen grossissement, par exemple x10, x20 . . . , du contenu de la plaque de culture 4. La plaque de fond 11 peut être retirée notamment pour réaliser une imagerie microscope à fort grossissement, ou pour réaliser une imagerie confocale du contenu de la plaque de culture 4, ou encore pour une manipulation de la boîte de culture 1 par des automates de laboratoire.The culture box 1 can be used with or without the bottom plate 11. The bottom plate 11 makes it possible to protect, in particular during handling, the at least one culture plate 4 positioned in the housing 2 of the intermediate element 12. In addition, the bottom plate 11 has characteristics of thickness and transparency allowing microscope imaging at medium magnification, for example x10, x20. . . , of the contents of the culture plate 4. The bottom plate 11 can be removed in particular to carry out high-magnification microscope imaging, or to carry out confocal imaging of the contents of the culture plate 4, or even for manipulation of the culture box 1 by laboratory automation.
Le logement 2 de la boîte de culture 1 est destiné à positionner et maintenir une plaque de culture 4 comme par exemple une plaque de culture 4 pour une application microfluidique. Housing 2 of culture box 1 is intended to position and hold a culture plate 4, for example a culture plate 4 for a microfluidic application.
La plaque de culture 4 selon l’invention est plus particulièrement illustrée en figures 8 à 11. La plaque de culture 4 comprend au moins un bord 41 configuré pour coopérer avec le dispositif de fixation 23 de la boîte de culture 1. Autrement dit, la plaque de culture 4 comprend un bord 41 pouvant être inséré dans l’espace de maintien. The culture plate 4 according to the invention is more particularly illustrated in Figures 8 to 11. The culture plate 4 comprises at least one edge 41 configured to cooperate with the fixing device 23 of the culture box 1. In other words, the culture plate 4 includes an edge 41 which can be inserted into the holding space.
Selon un mode de réalisation, le bord 41 de la plaque de culture 4 a une épaisseur constante. Ainsi, la plaque de culture 4 est facile à fabriquer. According to one embodiment, the edge 41 of the culture plate 4 has a constant thickness. Thus, the culture plate 4 is easy to manufacture.
Selon un mode de réalisation, le bord 41 de la plaque de culture 4 comprend au moins une encoche 44 destinée à coopérer avec le dispositif de fixation 23 de la boîte de culture. Ainsi l’épaisseur de la plaque de culture 4 au niveau du dispositif de fixation 23 est réduite. La plaque de culture 4 présente donc une zone de maintien 441 qui est facilement déformable et qui est positionnée au niveau du dispositif de fixation 23. Cette zone de maintien 441 déformable permet de faciliter l’introduction et le retrait de la plaque de culture 4 de la boîte de culture 1. En effet, seul cette zone de maintien 441 sera déformée et non l’ensemble de la plaque de culture 4. Il n’y pas donc de risque de déversement du contenu de la plaque de culture 4 lors de l’introduction ou du retrait de cette dernière. According to one embodiment, the edge 41 of the culture plate 4 comprises at least one notch 44 intended to cooperate with the fixing device 23 of the culture box. Thus the thickness of the culture plate 4 at the level of the fixing device 23 is reduced. The culture plate 4 therefore has a holding zone 441 which is easily deformable and which is positioned at the level of the fixing device 23. This deformable holding zone 441 makes it possible to facilitate the introduction and removal of the culture plate 4 from the culture box 1. Indeed, only this holding zone 441 will be deformed and not the entire culture plate 4. There is therefore no risk of spilling the contents of the culture plate 4 when introducing or removing the latter.
Selon un mode de réalisation, la plaque de culture 4 présente une forme non symétrique, par exemple elle a une forme sensiblement rectangulaire avec trois angles arrondis et un angle droit. La forme permet de réaliser un détrompeur permettant de facilement orienter ladite plaque de culture 4. According to one embodiment, the culture plate 4 has a non-symmetrical shape, for example it has a substantially rectangular shape with three rounded corners and one right angle. The shape makes it possible to create a key allowing said culture plate 4 to be easily oriented.
Selon un mode de réalisation, la plaque de culture 4 comprend une deuxième surface d’élongation 45 comprenant au moins un puit 42 de culture. According to one embodiment, the culture plate 4 comprises a second elongation surface 45 comprising at least one culture well 42.
Selon un mode de réalisation, la plaque de culture 4 comprend une deuxième surface d’élongation 45, parallèle à la première surface d’élongation 43. According to one embodiment, the culture plate 4 comprises a second elongation surface 45, parallel to the first elongation surface 43.
Selon un mode de réalisation, la première surface d’élongation 43 est espacée de la deuxième surface d’élongation 45 par une épaisseur constante. According to one embodiment, the first elongation surface 43 is spaced from the second elongation surface 45 by a constant thickness.
Lorsque la plaque de culture 4 est introduite dans le logement 2, la plaque de culture 4 et plus précisément la première surface d’élongation 43 vient au contact de la surface d’introduction 231 du dispositif de fixation 23. La zone de maintien 441 est alors localement déformée par la surface d’introduction 231 de sorte à permettre l’insertion de la plaque de culture 4 dans le logement 2. Lorsque la plaque de culture 4 est suffisamment insérée dans le logement 2, la zone de maintien 441 est positionnée dans l’espace de maintien et ne subit plus aucune force ou contrainte mécanique pouvant entrainer une déformation de la plaque de culture 4, et la première surface d’élongation 43 est en contact avec la surface d’appui 22 de l’élément intermédiaire 12. When the culture plate 4 is introduced into the housing 2, the culture plate 4 and more precisely the first elongation surface 43 comes into contact with the introduction surface 231 of the fixing device 23. The holding zone 441 is then locally deformed by the insertion surface 231 so as to allow the insertion of the culture plate 4 into the housing 2. When the culture plate 4 is sufficiently inserted into the housing 2, the holding zone 441 is positioned in the holding space and no longer undergoes any force or mechanical stress which could cause deformation of the culture plate 4, and the first elongation surface 43 is in contact with the support surface 22 of the intermediate element 12.
En outre, la boîte de culture 1 selon l’invention coopère avec un module complémentaire 3 illustré aux figures 5 à 7. Selon un mode de réalisation, le module complémentaire 3 est physiquement indépendant de la boîte de culture 1. Autrement dit, il n’y a pas de lien physique entre la boîte de culture 1 et le module complémentaire 3 qui peut donc être éloigné de la boîte de culture 1 d’une distance non prédéterminée. Plus précisément, il peut être positionné de chaque côté de l’élément intermédiaire 12. Furthermore, the culture box 1 according to the invention cooperates with an additional module 3 illustrated in Figures 5 to 7. According to one embodiment, the complementary module 3 is physically independent of the culture box 1. In other words, it There is no physical link between the culture box 1 and the complementary module 3 which can therefore be moved away from the culture box 1 by a non-predetermined distance. More precisely, it can be positioned on either side of the intermediate element 12.
Selon un mode de réalisation, le module complémentaire a une forme qui permet son insertion dans le logement de la boîte de culture. According to one embodiment, the complementary module has a shape which allows its insertion into the housing of the culture box.
Selon un mode de réalisation, le module complémentaire 3 a une forme symétrique. According to one embodiment, the complementary module 3 has a symmetrical shape.
Selon un mode de réalisation, le module complémentaire a une forme non symétrique, par exemple il a une forme sensiblement rectangulaire avec trois angles arrondis et un angle droit. La forme permet de réaliser un détrompeur permettant de facilement orienter ledit module complémentaire 3. According to one embodiment, the complementary module has a non-symmetrical shape, for example it has a substantially rectangular shape with three rounded corners and one right angle. The shape makes it possible to create a key allowing easy orientation of said complementary module 3.
Selon un mode de réalisation, le module complémentaire 3 à une forme identique à celle de la plaque de culture 4. Le module complémentaire 3 permet de retirer facilement la plaque de culture 4 du logement 2. Pour cela, le module complémentaire 3 comprend une surface de retrait 31 configurée pour venir partiellement en contact avec la première surface d’élongation 43 de la plaque de culture 4. La surface de retrait 31 a pour objectif de soutenir la plaque de culture 4 lors de son retrait du logement 2 en évitant une déformation de cette dernière. La surface de retrait 31 vient donc au contact de la première surface d’élongation 43, et plus particulièrement d’une zone centrale de la première surface d’élongation 43. According to one embodiment, the complementary module 3 has a shape identical to that of the culture plate 4. The complementary module 3 makes it possible to easily remove the culture plate 4 from the housing 2. For this, the complementary module 3 comprises a removal surface 31 configured to come partially into contact with the first elongation surface 43 of the culture plate 4 The purpose of the withdrawal surface 31 is to support the culture plate 4 when it is removed from the housing 2 while avoiding deformation of the latter. The withdrawal surface 31 therefore comes into contact with the first elongation surface 43, and more particularly with a central zone of the first elongation surface 43.
Selon un mode de réalisation, la surface de retrait 31 s’étend sensiblement dans un plan de retrait. According to one embodiment, the withdrawal surface 31 extends substantially in a withdrawal plane.
Le module complémentaire 3 comprend également au moins un élément de retrait 32 configuré pour être positionné en regard d’un dispositif de fixation 23, et pour exercer une force localisée sur la plaque de culture 4 au niveau du dispositif de fixation 23. The complementary module 3 also comprises at least one removal element 32 configured to be positioned opposite a fixing device 23, and to exert a localized force on the culture plate 4 at the level of the fixing device 23.
Selon un mode de réalisation, le module complémentaire 3 comprend autant d’élément de retrait 32 que le logement 2 comprend de dispositif de fixation 23. According to one embodiment, the complementary module 3 includes as many removal elements 32 as the housing 2 includes fixing devices 23.
Pour retirer une plaque de culture 4 du logement 2, le module complémentaire 3 est positionné en regard de la première surface d’élongation 43 de la plaque de culture 4 comme illustré en figure 13. Puis on amène le module complémentaire 3 en contact de ladite première surface d’élongation 43 comme illustré en figure 14. La plaque de culture 4 est alors positionnée sur la surface de retrait 31 et sur les éléments de retrait 32 du module complémentaire 3. La plaque de culture 4 est alors extraite du logement 2 et peut être ôtée du module complémentaire 3. To remove a culture plate 4 from housing 2, the complementary module 3 is positioned opposite the first elongation surface 43 of the culture plate 4 as illustrated in Figure 13. Then the complementary module 3 is brought into contact with said first elongation surface 43 as illustrated in Figure 14. The culture plate 4 is then positioned on the removal surface 31 and on the removal elements 32 of the complementary module 3. The culture plate 4 is then extracted from the housing 2 and can be removed from add-on 3.
L’élément de retrait 32 permet d’exercer une force localisée sur la plaque de culture 4 de sorte à réaliser une déformation locale de la plaque de culture 4, préférentiellement au niveau de la zone de maintien 441 de la plaque de culture 4, ou, par l’intermédiaire de la plaque de culture 4, une déformation du dispositif de fixation 23, afin de retirer la plaque de culture 4 de la boîte de culture 1 sans déformer cette dernière de manière globale. The withdrawal element 32 makes it possible to exert a localized force on the culture plate 4 so as to produce a local deformation of the culture plate 4, preferably at the level of the holding zone 441 of the culture plate 4, or , via the culture plate 4, a deformation of the fixing device 23, in order to remove the culture plate 4 from the culture box 1 without deforming the latter overall.
Selon un mode de réalisation, la surface de retrait 31 et l’élément de retrait 32 s’étendent sensiblement dans un même plan. Ainsi, la surface de retrait 31 et l’élément de retrait 32 constitue un support plan à la plaque de culture 4 qui peut être souple, ce qui limite la propension de la plaque de culture 4 à emmagasiner de l'énergie en flexion. En effet, la plaque de culture 4 a tendance à restituer cette énergie en à-coup ou soubresaut, faisant gicler ou se déverser le contenu des puits 42 de culture. According to one embodiment, the withdrawal surface 31 and the withdrawal element 32 extend substantially in the same plane. Thus, the withdrawal surface 31 and the withdrawal element 32 constitute a plane support for the culture plate 4 which can be flexible, which limits the propensity of the culture plate 4 to store energy in bending. Indeed, the culture plate 4 tends to restore this energy in a jerk or jolt, causing the contents of the culture wells 42 to squirt or spill.
Selon un mode de réalisation, l’élément de retrait 32 a une dimension permettant d’être positionné de part et d’autre de l’encoche 44 du bord de la plaque de culture 4 de sorte à permettre une déformation de ladite encoche 44, et plus particulièrement de la zone de maintien 441. Selon un mode de réalisation, le module complémentaire 3 peut être inséré dans le logement 2 à la place d’une plaque de culture 4 comme illustré en figure 15. Pour cela, le module complémentaire 3 comprend au moins une surface de support 33 configurée pour venir en appui sur la surface d’appui 22. Selon un mode de réalisation, la surface de support 33 du module complémentaire 3 est sensiblement parallèle à la surface de retrait 31. According to one embodiment, the removal element 32 has a dimension allowing it to be positioned on either side of the notch 44 of the edge of the culture plate 4 so as to allow deformation of said notch 44, and more particularly the holding zone 441. According to one embodiment, the complementary module 3 can be inserted into the housing 2 in place of a culture plate 4 as illustrated in Figure 15. For this, the complementary module 3 comprises at least one support surface 33 configured to come to rest on the support surface 22. According to one embodiment, the support surface 33 of the complementary module 3 is substantially parallel to the withdrawal surface 31.
Selon un mode de réalisation, la surface de support 33 est espacée de la surface de retrait 31 par une épaisseur constante. According to one embodiment, the support surface 33 is spaced from the recess surface 31 by a constant thickness.
Selon un mode de réalisation, le module complémentaire 3 comprend au moins un bord 34, configuré pour coopérer avec l’au moins un dispositif de fixation 23 de la boîte de culture 1 . Ainsi le module complémentaire 3 peut être inséré dans l’espace de maintien du dispositif de fixation 23. According to one embodiment, the complementary module 3 comprises at least one edge 34, configured to cooperate with the at least one fixing device 23 of the culture box 1. Thus the complementary module 3 can be inserted into the holding space of the fixing device 23.
Selon un mode de réalisation, le bord 34 du module complémentaire 3 a une épaisseur constante. According to one embodiment, the edge 34 of the complementary module 3 has a constant thickness.
Ainsi, le module complémentaire 3 est facile à fabriquer. So Addon 3 is easy to make.
Selon un mode de réalisation, le bord 34 du module complémentaire 3 comprend au moins une encoche 341 destinée à coopérer avec l’au moins un dispositif de fixation 23 de la boîte de culture 1. According to one embodiment, the edge 34 of the complementary module 3 comprises at least one notch 341 intended to cooperate with the at least one fixing device 23 of the culture box 1.
Ainsi l’épaisseur du module complémentaire 3 au niveau du dispositif de fixation 23 est réduite afin de faciliter l’introduction et le retrait du module complémentaire 3 de la boîte de culture 1.Thus the thickness of the complementary module 3 at the level of the fixing device 23 is reduced in order to facilitate the introduction and removal of the complementary module 3 from the culture box 1.
Selon un mode de réalisation, le module complémentaire 3 comprend au moins un moyen fonctionnel parmi : un moyen humidificateur 35, un moyen lumineux, un moyen de ventilation, un moyen de mesure chimique, un moyen de mesure d’acidité, un moyen de mesure d’humidité, un moyen de chauffage, un moyen d’ajouter ou de retirer au moins un fluide, un moyen de mesure biologique, un moyen de mesure d’une déformation mécanique d’au moins une plaque de culture 4 contiguë audit moyen de mesure de la déformation mécanique, un moyen de simulation. According to one embodiment, the complementary module 3 comprises at least one functional means from: a humidifier means 35, a light means, a ventilation means, a chemical measuring means, an acidity measuring means, a measuring means humidity, a heating means, a means of adding or removing at least one fluid, a means of biological measurement, a means of measuring a mechanical deformation of at least one culture plate 4 contiguous to said means of measurement of mechanical deformation, a means of simulation.
Ainsi lorsque le module complémentaire 3 est positionné dans la boîte de culture 1 , il amène un moyen fonctionnel supplémentaire. So when the complementary module 3 is positioned in the culture box 1, it provides an additional functional means.
Le moyen humidificateur 35 peut être identique à celui de l’élément intermédiaire 12 c'est-à-dire que le moyen humidificateur 35 entoure de manière continue un bord 34 du module complémentaire 3 de sorte qu’un liquide peut se répartir sur l’ensemble du bord 34 du module complémentaire 3. Le moyen humidificateur 35 comprend des éléments de méandre permettant notamment d’amortir et de contrôler un mouvement du fluide. Le module complémentaire 3 positionne le moyen humidificateur 35 au plus proche des puits adjacents des plaques de culture 4, de façon à limiter une distance entre les puits et la source d’humidification. Bien entendu, l’invention n’est pas limitée aux modes de réalisation décrits et représentés aux figures annexées. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d’équivalents techniques, sans sortir pour autant du domaine de protection de l’invention. The humidifying means 35 can be identical to that of the intermediate element 12, that is to say that the humidifying means 35 continuously surrounds an edge 34 of the complementary module 3 so that a liquid can be distributed over the entire edge 34 of the complementary module 3. The humidifier means 35 comprises meander elements making it possible in particular to dampen and control a movement of the fluid. The complementary module 3 positions the humidifier means 35 as close as possible to the adjacent wells of the culture plates 4, so as to limit a distance between the wells and the humidification source. Of course, the invention is not limited to the embodiments described and represented in the appended figures. Modifications remain possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
