Title (EN) PROCESS AND APPARATUS FOR TRANSFERRING AND STERILIZING A SOLUTION
(FR) PROCEDE ET DISPOSITIF DE TRANSFERT ET DE STERILISATION D'UNE SOLUTION
Abstract: front page image
(EN)Process and apparatus for the transfer of a parenteral solution into an extensible plastic bag (32) and the sterilization of that solution during such transfer. The apparatus includes a hydrophilic, bacterial organism retentive, sterilizing filter (20), such a bag (32), and tubing (18) connecting same, which have been combined and sterilized as a unit, which unit is labeled for sale as being sterile. A container (10, 12) holding the solution to be transferred and tubing (18) associated therewith are provided for delivery of the solution to the sterile unit. A vacuum chamber (34) is also provided by which the solution may be rapidly drawn through the filter (20), as it is sterilized, and into the bag (32) upon the creation of a pressure differential between the inside and outside of the bag in the vacuum chamber (34). A transparent portion of the sterile unit provides a means by which the sterility of the transfer process can be determined. The process includes delivering the solution to the sterile unit, transferring the solution through the filter (20) for sterilization and into the bag by creating the pressure differential, terminating solution transfer and directing a gas through the unit, observing the transparent portion for the presence of gas bubbles, which would indicate a loss of filter integrity, and consequently sterility of the unit, and hermetically sealing off the bag (32), if no such bubbles are present.
(FR)Procede et dispositif de transfert d'une solution parenterale dans un sachet en plastique extensible (32) et de sterilisation de cette solution pendant le transfert. Le dispositif se compose d'un filtre (20) de sterilisation, hydrophile, retenant les organismes bacteriens, dudit sachet (32), et des tuyaux (18) le connectant, qui ont ete assembles et sterilises en tant qu'unite cette unite etant designee pour la vente comme etant sterile. Un recipient (10, 12) contenant la solution a transferer et les tuyaux (18) correspondants sont prevus pour debiter la solution a l'unite sterile. Une chambre a vide (34) est aussi prevue grace a laquelle la solution peut circuler rapidement au travers du filtre (20), ou elle est sterilisee, et dans le sachet (32) par la creation d'une difference de pression entre l'interieur et l'exterieur du sachet dans la chambre a vide (34). Une partie transparente de l'unite sterile constitue un moyen par lequel la sterilite du procede de transfert peut etre determinee. Le procede comprend le transfert de la solution dans l'unite sterile, et ensuite le transfert de la solution au travers du filtre (20) pour la sterilisation et dans le sachet par la creation d'une difference de pression, l'arret du transfert de la solution et la circulation d'un gaz au travers de l'unite, l'observation de la partie transparente pour detecter la presence de bulles de gaz, qui indiqueraient une perte d'integrite du filtre, et par consequent de la sterilite de l'unite, et le scellement hermetique du sachet (32), si de telles bulles ne sont pas observees.
