Patent

CA 2736180

A reusable continuously sealing one-way valve assembly and delivery system flows a sterile flowable substance from a source to an outlet orifice and prevents any backflow of contaminants through the continuously sealing one way valve assembly when the flowable substance ceases to flow. The valve assembly includes an elastomeric membrane which aids in preventing any backflow of contaminants when dispensing of the flowable substance is stopped. Multiple dosing of preservative-free flowable substance is provided.

La présente invention concerne un ensemble de soupape unidirectionnel à scellage continu réutilisable et un système d'apport qui font circuler une substance fluide stérile d'une source à un orifice de refoulement et empêche tout contre-courant de contaminants à travers l'ensemble de soupape unidirectionnel à scellage continu lorsque la substance fluide cesse de s'écouler. L'ensemble de soupape comprend une membrane élastomère qui aide à empêcher un contre-courant quelconque de contaminants lorsque la distribution de la substance fluide est arrêtée. Un dosage multiple d'une substance fluide sans conservateur est proposé.
