Abstract

A.FILTRE PERFECTIONNE POUR DEGAZER UN LIQUIDE. B.IL COMPREND UN ORGANE FILTRANT HYDROPHILE MONTE DANS UNE ENVELOPPE, SUR LE TRAJET DU COURANT DE LIQUIDE ET NE PERMETTANT QUE LE PASSAGE DE CE DERNIER. LES GAZ SEPARES DU LIQUIDE SONT EVACUES PAR DES EVENTS COUVERTS PAR UNE MEMBRANE FILTRANTE HYDROPHOBE QUI NE PERMET QUE LE PASSAGE DES GAZ. UNE VALVE AUTOMATIQUE EST UTILISEE POUR FERMER LES EVENTS DE FACON A EMPECHER L'ENTREE DE L'AIR AMBIANT, CETTE VALVE S'OUVRANT AUTOMATIQUEMENT POUR RELACHER LES GAZ DU FILTRE. C.APPLICATION NOTAMMENT AUX APPAREILS DESTINES A ADMINISTRER DES LIQUIDES A DES ETRES VIVANTS ET EN PARTICULIER A DES PATIENTS PAR VOIE PARENTERALE.
