The invention concerns a test sample card (1) comprising at least: an orifice for introducing a fluid sample in the card (1); an intake compartment (3) for receiving, directly or indirectly, all or part of the sample introduced, and a primary flow path for transporting said sample from the insertion orifice to the intake compartment (3) (direct transfer), or from an intermediate compartment towards said intake compartment (indirect transfer). The invention is characterised in that each intermediate or intake compartment (3) is connected to a buffer supply (5), located in the card (1), which is so arranged and configured prevent the card from being filled by the introduced sample. The invention is particularly applicable to microfluidic devices used in biology.
La présente invention concerne une carte d'analyse (1) comportant au moins: une ouverture pour l'introduction d'un échantillon fluidique dans la carte (1), un compartiment d'arrivée (3) qui peut recevoir, directement ou indirectement, tout ou partie de l'échantillon introduit, et un canal primaire d'amenée dudit échantillon de l'ouverture d'introduction vers le compartiment d'arrivée (3) (transfert direct), ou d'un compartiment intermédiaire vers ledit compartiment d'arrivée (3) (transfert indirect). Elle consiste dans le fait que chaque compartiment intermédiaire ou d'arrivée (3) est relié à un volume tampon (5), situé au sein de la carte (1), dont la disposition et la configuration empêchent le remplissage par l'échantillon introduit. L'invention trouve une application préférentielle dans le domaine de la microfluidique appliquée à la biologie.
