The invention concerns a pumping device (1) for transferring a fluid sample (2) into a sealed consumable (3), the transfer being performed between at least a first compartment, said to be initial, (4) and at least a second compartment, said to be, receiving, (5) via a narrowed section such as a flow path (6). The invention is characterised in that the point of intersection between an initial compartment (4) and the narrowed section is located in the lower part, and preferably at the lowest level, of said initial compartment (4), that the point of intersection between the receiving compartment (5) and said narrowed part is located in the upper part, and preferably at the highest level, of said receiving compartment (5), and at least one of the initial (4) and/or receiving (5) compartment can be deformed, such that each deformation activates the transfer of all or part of the sample (2), The invention is particularly applicable to microfluidic devices used in biology.
La présente invention concerne un dispositif de pompage (1) pour permettre le transfert d'un échantillon fluidique (2) dans un consommable scellé (3), le transfert s'effectuant entre au moins un premier compartiment, dit de départ (4), et au moins un second compartiment, dit d'arrivée (5), via un rétrécissement tel qu'un canal (6). Elle consiste en ce que le point d'intersection entre un compartiment de départ (4) et le rétrécissement est positionné en partie inférieure, et préférentiellement au niveau le plus bas, de ce compartiment de départ (4), que le point d'intersection entre un compartiment d'arrivée (5) et ledit rétrécissement est positionné en partie supérieure, et préférentiellement au niveau le plus haut, de ce compartiment d'arrivée (5), et qu'au moins un des compartiments de départ (4) et/ou d'arrivée (5) peut être déformé, de sorte que chaque déformation actionne le transfert de tout ou partie de l'échantillon (2). L'invention trouve une application préférentielle dans le domaine de la micro-fluidique appliquée à la biologie.
