Title (EN) NOVEL VALVE EMPLOYING HYDROPHOBIC AND HYDROPHILIC MEMBRANES
(FR) NOUVELLE SOUPAPE UTILISANT DES MEMBRANES HYDROPHOBES ET HYDROPHILES
Abstract: front page image
(EN)Gravitational flow system and equipment sets for the sequential administration of medical liquids wherein a primary liquid from a first source (11) can be administered at a flow rate independent of the flow rate of secondary liquid in a second source (13). A combined air barrier and liquid sequencing valve chamber (32) controls the sequencing of the various flows and prevents inadvertent administration of air when the second source is depleted by means of a hydrophilic barrier (45). The valve chamber (32) is divided into two separate flow chambers (34, 41) which are in liquid communication with the respective sources (11, 13) and in air communication therebetween by means of hydrophobic membrane (53).
(FR)Des systemes et dispositifs d"ecoulement par gravite permettent l"administration sequentielle de liquide medicaux ou un premier liquide d"une premiere source (11) peut etre administre a une vitesse d"ecoulement independante de la vitesse d"ecoulement d"un second liquide d"une seconde source (13). Une barriere d"air combinee a une soupape de sequence ou concordance des liquides ayant une chambre (32) commande la concordance des differents debits et empeche l"introduction accident elle d"air lorsque la seconde source est epuisee au moyen d"une barriere hydrophile (45). La chambre de soupape (32) est divisee en deux chambres de debit separees (34, 41) qui sont en communication pour le passage des liquides avec les sources respectives (11, 13) et qui communiquent entre elles pour le passage d"air au moyen d"une membrane hydrophobe (53).
