Summary:A microfluidic device and associated manufacturing process, where said microfluidic device is adapted to be in fluid communication with a fluidic platform, and comprises a structure (1) that in turn comprises a preload chamber (7), at least one orifice for purge and fill (2, 3), a release orifice (4), a cavity (11) through which a plunger (5) configured to move longitudinally along said cavity (11) is inserted, and a membrane (8) arranged adjacent to the release hole (4), keeping the preload chamber (7) hermetic in a state of rest, and dimensioned to allow the passage of the fluid (12) from the preload chamber (7) to the microfluidic circuit (6) by moving the plunger (5) longitudinally over the cavity (11). (Machine-translation by Google Translate, not legally binding) Un dispositivo microfluídico y procedimiento de fabricación asociado, donde dicho dispositivo microfluídico está adaptado para estar en comunicación fluida con una plataforma fluídica, y comprende una estructura (1) que comprende a su vez una cámara de precarga (7), al menos un orificio de purga y llenado (2, 3), un orificio de liberación (4), una cavidad (11) por la cual es insertado un émbolo (5) configurado para desplazarse longitudinalmente a largo de dicha cavidad (11), y una membrana (8) dispuesta contigua al orificio de liberación (4), manteniendo la cámara de precarga (7) hermética en un estado de reposo, y dimensionada para permitir el paso del fluido (12) desde la cámara de precarga (7) hasta el circuito microfluídico (6) al desplazar el émbolo (5) longitudinalmente sobre la cavidad (11).
