  • Patent number: 6086574
    Abstract: A fluid delivery system includes a flexible media bag having an outlet spout projecting therefrom. A passageway longitudinally extends through the outlet spout and communicates with the interior of the media bag. A diptube connector is mounted to the outlet spout. The diptube connector includes a stem having a first end with a barb radially projecting out therefrom and an opposing second end with an annular flange radially projecting out therefrom. The flange has an outer diameter greater than the inner diameter of the passageway in the outlet spout. The first end of the diptube connector is received in sealed engagement within the first end of the diptube. The second end of the diptube is passed through the passageway in the outlet spout such that the flange on the diptube connector rests on the outlet spout. The outlet spout having the diptube connector mounted thereon is received in sealed engagement within a delivery tube.

  • Patent number: 5799830
    Abstract: A disposable fluid transport system is provided for dispensing sterile fluids from a pressure vessel. The pressure vessel has an internal chamber with an outlet opening extending therethrough. The fluid transport system includes a collapsible media bag having an internal compartment defining a sterile environment. A first end of a delivery tube is attached in fluid communication to the compartment of the media bag. Disposed at a point along the length of a delivery tube is an interface adapter. The interface adapter includes an annular flange which encircles and radially projects out from the exterior surface of the delivery tube. The gasket is formed of a resiliently flexible material and has an outside diameter that is larger than the inside diameter of the outlet opening on the pressure vessel. Once the media bag and delivery tube are positioned within the chamber of the pressure vessel, the second end of the delivery tube can be fed out the outlet opening.
