Abstract

Un assieme filtro, particolarmente per linee d'infusione e trasfusione medicale, comprende un corpo principale cavo (5) con uno o più canali d'ingresso (7) ed un canale d'uscita (8) per un fluido medicale, collegati reciprocamente da una camera di filtraggio (6), un punto d'iniezione (9) per l'introduzione di ulteriori fluidi in una posizione a monte della camera di filtraggio (6), formato in un corpo secondario (10) unito al corpo principale (5) in modo tale da risultare, durante l'uso, ad un livello superiore rispetto alla camera di filtraggio; quest'ultima comprende una sottocamera di ristagno inferiore (6') ed una sottocamera collettrice superiore (6"), separate in senso longitudinale e per tutta la loro estensione da un tessuto o una membrana filtrante (14). Il corpo secondario (10) ed il canale o i canali d'ingresso (7) sono collegati alla zona d'ingresso (12) della sottocamera di ristagno inferiore (6'), la sottocamera collettrice superiore (6") presenta una sezione trasversale crescente nella direzione d'avanzamento del fluido, ed è collegata al canale d'uscita nel punto più alto (15) della sua massima sezione trasversale per favorire l'espulsione dell'aria.
