Description

ROTOR POUR DISPOSITIF D'ANALYSE A CENTRIFUGATION
La présente invention se rapporte à un rotor pour un dispositif d'analyse, ce rotor comportant sur sa périphérie, de maniere connue, une pluralité de cellules dans lesquelles un liquide à analyser est distribué à partir d'une cuve centrale, par la mise en rotation du rotor.ROTOR FOR CENTRIFUGAL ANALYSIS DEVICE
The present invention relates to a rotor for an analysis device, this rotor comprising on its periphery, in a known manner, a plurality of cells in which a liquid to be analyzed is distributed from a central tank, by setting rotor rotation.

Un inconvénient des dispositifs actuellement connus réside dans un relatif manque de souplesse d'utilisation, puisque ces dispositifs ne permettent l'analyse que d'un seul liquide à la fois alors que, souvent, le nombre des cellules périphériques est surabondant. A drawback of the currently known devices lies in a relative lack of flexibility of use, since these devices allow the analysis of only one liquid at a time while, often, the number of peripheral cells is overabundant.

Un objet de la présente invention est la réalisation d'un rotor pour dispositif d'analyse de ce genre, permettant d'éviter cet inconvénient et d'utiliser un seul et unique rotor pour la conduite simultanée d'analyses sur divers échantillons de liquides. An object of the present invention is the production of a rotor for such an analysis device, making it possible to avoid this drawback and to use a single rotor for the simultaneous conduct of analyzes on various samples of liquids.

Le rotor selon l'invention, pour dispositif d'analyse à centrifugation, comportant une cuve centrale pour la répartition du liquide à analyser et sur son pourtour une pluralité de cellules d'analyse raccordées par des conduits radiaux à ladite cuves est caractérisé en ce que la cuve centrale est divisée en plusieurs éléments de cuve distincts par des cloisons -radiales, un groupe de cellules étant associé à chacun desdits éléments et y étant raccordé par les conduits radiaux correspondants. The rotor according to the invention, for a centrifugal analysis device, comprising a central tank for the distribution of the liquid to be analyzed and around its periphery a plurality of analysis cells connected by radial conduits to said tanks is characterized in that the central tank is divided into several distinct tank elements by -radial partitions, a group of cells being associated with each of said elements and being connected thereto by the corresponding radial conduits.

Selon une autre caractéristique, une couronne annulaire entourant la cuve centrale porte les cellules d'analyse, les cloisons radiales s'etendant du centre de la cuve jusqu'à ladite couronne. According to another characteristic, an annular ring surrounding the central tank carries the analysis cells, the radial partitions extending from the center of the tank to said ring.

Dans une forme de réalisation, un couvercle recouvrant la cuve est fixé à la couronne, ce couvercle comprenant des cheminées de distribution du liquide associées chacune à l'un des éléments de cuve
Selon un autre rnode de réalisation, le rotor comporte une base cylindrique et les cloisons radiales sont monobloc avec cette base du rotor. Dans un autre mode de réalisation, les cloisons radiales sont fixées au rotor. Chaque élément de cuve peut présenter la forme d'un prisme triangulaire ouvert à sa partie supérieure et est solidaire d'une portion de la couronne annulaire portant les cellules, chacun desdits éleménts de cuve étant disposé dans un logement du rotor formé par les cloisons radiales à la partie supérieure d'une embase de celui-ci.In one embodiment, a cover covering the tank is fixed to the crown, this cover comprising liquid distribution chimneys each associated with one of the tank elements
According to another embodiment, the rotor has a cylindrical base and the radial partitions are in one piece with this base of the rotor. In another embodiment, the radial partitions are fixed to the rotor. Each tank element may have the shape of a triangular prism open at its upper part and is integral with a portion of the annular ring carrying the cells, each of said tank elements being disposed in a housing of the rotor formed by the radial partitions. at the top of a base thereof.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs mieux de la description suivante, donnée uniquement à titre d'exemple, en référence aux dessins annexés dans lesquels
- la figure 1 est une vue éclatée, en perspective, d'une forme de réalisation du rotor selon l'invention, ce rotor comportant plusieurs éléments amovibles dont un seul est représenté ;
- la figue 2 est une autre vue éclatée d'une autre forme de réalisation du rotor selon l'invention.The characteristics and advantages of the invention will emerge more clearly from the following description, given solely by way of example, with reference to the accompanying drawings in which
- Figure 1 is an exploded perspective view of an embodiment of the rotor according to the invention, this rotor comprising several removable elements of which only one is shown;
- Fig 2 is another exploded view of another embodiment of the rotor according to the invention.

Dans la forme de réalisation de la figure 1, le rotor comporte un support 1 constitué d'une base cylindrique 2 sur laquelle sont fixées une pluralité de cloisons radiales 3 partant de l'axe de cette base ; ces cloisons 3 régulièrement réparties ménagent des logements 4 en forme de prismes triangulaires égaux ouverts sur la périphérie dudit support 1 qui présente six logements 4. A chacun d'eux est associé un élément 5 comprenant une cuve 6, ouverte à sa partie supérieure et de forme extérieure complémentaire à celle du logement 4. La cuve se prolonge par une aile horizontale 7 qui porte des cellules d'analyse 8 raccordées à la cuve 6 par des conduits ménagés dans sa masse et non visibles, chaque élément 5 comportant par exemple trois cellules d'analyse. Chaque logement 4 comporte des moyens de retenue (non représentés) de l'élément associé. In the embodiment of Figure 1, the rotor comprises a support 1 consisting of a cylindrical base 2 on which are fixed a plurality of radial partitions 3 starting from the axis of this base; these partitions 3 regularly distributed provide housings 4 in the form of equal triangular prisms open on the periphery of said support 1 which has six housings 4. To each of them is associated an element 5 comprising a tank 6, open at its upper part and of external shape complementary to that of the housing 4. The tank is extended by a horizontal wing 7 which carries analysis cells 8 connected to the tank 6 by conduits formed in its mass and not visible, each element 5 comprising for example three cells analysis. Each housing 4 includes means for retaining (not shown) the associated element.

Ainsi, il est possible d'utiliser chacun des éléments 5 pour un échantillon de liquide différent, ce qui augmente les possibilités d'emploi du rotor. Thus, it is possible to use each of the elements 5 for a different liquid sample, which increases the possibilities of using the rotor.

Une autre forme de réalisation du rotor selon l'invention est représentée à la figure 2. Another embodiment of the rotor according to the invention is shown in FIG. 2.

Ce rotor 10 est constitué de deux parties, un socle 11 et un couvercle 20. Le socle 11 comporte une couronne circulaire 12 dans laquelle sont ménagées des cellules d'analyse 13 régulièrement réparties sur cette couronne en groupe(de cinq dans cet exemple) raccordés chacun à un élément central de cuve 14 par des conduits non représentes. Les éléments de cuve 14 sont ménagés par des cloisons radiales 15, au nombre de quatre dans la solution représentée, divisant un logement central du socle 11, bordé par la couronne 12. This rotor 10 consists of two parts, a base 11 and a cover 20. The base 11 comprises a circular crown 12 in which are provided analysis cells 13 regularly distributed on this crown in groups (of five in this example) connected each to a central tank element 14 by pipes not shown. The tank elements 14 are formed by radial partitions 15, four in number in the solution shown, dividing a central housing of the base 11, bordered by the crown 12.

Le couvercle 20 presente la forme génerale d'un disque 21 de même diamètre que la couronne 12, et est destine à être pose sur le socle 11 en recouvrant le logement central de celui-ci et donc les éléments de cuve 14, des moyens (non représentés) assuJettissant ce couvercle 20 audit socle 11. The cover 20 has the general shape of a disc 21 of the same diameter as the crown 12, and is intended to be placed on the base 11 by covering the central housing thereof and therefore the tank elements 14, means ( not shown) subjecting this cover 20 to said base 11.

Des cheminees 22 sont ménagées dans le couvercle 20, une pour chacun des éléments de cuve 14 et permettent d'introduire un échantill-on de liquide à analyser dans chacun de ces éléments. Chimneys 22 are provided in the cover 20, one for each of the tank elements 14 and make it possible to introduce a sample of liquid to be analyzed in each of these elements.

Ce rotor présente les mêmes avantages que celui précédemment décrit et peut présenter un plus grand nombre d'éléments de cuve. This rotor has the same advantages as that previously described and can have a larger number of tank elements.

Bien entendu, la présente invention n'est pas limitée aux modes de réalisation décrits et représentés et elle est susceptible de nombreuses. variantes accessibles à l'homme de l'art, sans que l'on ne s'ecarte de l'esprit de l'invention.  Of course, the present invention is not limited to the embodiments described and shown and it is susceptible of numerous. variants accessible to those skilled in the art, without departing from the spirit of the invention.
