| description | A microfluidic fluid delivery system includes a microfluidic device (16) having a fluid input. A fluid reservoir (14) is fluidically coupled to the fluid input. A gas delivery system has a pulse generator (34, 34') that generates an electric pulse. An electrically operated valve (15, 30) is coupled to the pulse generator (34, 34') and the gas pressure source. The valve (15, 30) controls the gas pressure pulse in response to the electric pulse. The gas pressure pulse displaces fluid from the fluid reservoir (14) into the plurality of capillaries.
L'invention concerne un système microfluidique de distribution de fluide comprenant un dispositif microfluidique (16) doté d'une entrée de fluide. Un réservoir de fluide (14) est couplé de façon fluide à l'entrée de fluide. Un système de fourniture de gaz comprend un générateur d'impulsions (34, 34') qui génère une impulsion électrique. Une vanne à commande électrique (15, 30) est couplée au générateur d'impulsions (34, 34') et à la source de pression du gaz. La vanne (15, 30) commande l'impulsion de pression du gaz en réponse à une impulsion électrique. L'impulsion de pression du gaz déplace le fluide du réservoir de fluide (14) vers les multiples tubes capillaires. |
