Patent

CA 2342735

The invention concerns a device for performing a reaction or at least two reactions in parallel or in series, and for transferring a fluid flow, consisting of: an upper surface (2) and a lower surface (3) mutually linked by an edge (4); at least a duct (5) wherein a fluid flow (F1) can be generated by means transferring at least one sample (6) to be treated and/or analysed; and at least a valve (8) incorporated in each duct (4) for directing each sample (6) thereby controlling the transfers, reactions and analyses in the device. Each valve (8) consists of two means (9 and 10) integral with the device, the first means (9) being mobile between an inoperative position wherein the fluid transfer (6) is possible and an active position wherein said transfer cannot take place, and the second means (10) being mobile between a position wherein it is not in contact with said first means (9) and an active position wherein it deforms the first means (9) and it is activated by an actuator external to the device.

L'invention concerne un dispositif, permettant de conduire une réaction ou au moins deux réactions en parallèle ou en série et un transfert d'un flux fluidique, qui est constitué par une surface supérieure (2) et une surface inférieure (3) reliées l'une à l'autre par un bord (4), au moins un canal (5) dans lequel un flux fluidique (F1) peut être créé par des moyens de transfert d'au moins un échantillon (6) à traiter et/ou à analyser, et au moins une vanne (8) incorporée à chaque canal (5) permettant l'orientation de chaque échantillon (6) et donc le contrôle des transferts, des réactions et des analyses. Chaque vanne (8) est constituée de deux moyens (9 et 10) solidaires du dispositif, le premier moyen (9) étant mobile entre une position de repos où le transfert de fluide (6) est possible et une position active où ledit transfert est impossible, et le second moyen (10) étant mobile entre une position où il déforme le premier moyen (9) et activé par un actionneur extérieur.
