Abstract

L'invention concerne un dispositif de filtrage. Le dispositif comprend une chambre supérieure 18 et une chambre inférieure 20 le long de l'axe de dispositif, un filtre hydrophile 24 et une membrane hydrophobe 26 séparant les chambres, la membrane étant en service à un niveau plus bas que le filtre hydrophile. Un réservoir de gaz 36 est formé dans la chambre inférieure au-dessus de la membrane et en dessous du filtre, et un réservoir de liquide 38 se forme dans la chambre supérieure au-dessus de la membrane et en dessous du filtre, car en fonctionnement, du liquide est emprisonné dans le réservoir 38 et interdit le passage du gaz et du gaz est emprisonné dans le réservoir 36 et interdit le reflux du liquide. Application à des appareils d'injection de médicaments.
