  • Patent number: 6996951
    Abstract: A flexible container is provided for the storage and administration of medical solutions. The container incorporates a transparent front sheet made from a planar layer of a polymer and an opposing rear sheet. The rear sheet is made from a planar laminate layer. The front and rear sheets are sealed together along a common peripheral edge to form a volume enclosure. The volume enclosure is constructed of materials having high oxygen and moisture barrier properties which allows the container thermoplastic to be stored for extended periods of time without degrading the contents. The volume enclosure is then inflated with a pressurized gas to permanently stretch the front and rear sheets outwardly and to thereby increase the volume capacity of the container. An alternative embodiment of the container incorporates multiple compartments, separated by peelable seals, for containing a diluent and a medicament.

  • Patent number: 5976115
    Abstract: A spike adapter and blunt cannula spike adapter assembly comprises a spike adapter having a hollow chamber extending axially therethrough from a first body end to a second body end. The hollow chamber is adapted to receive and accommodate attachment with a blunt cannula therein. A spike shaft projects axially outwardly away from the adapter body second end and has a sharpened tip at a distal end. A spike cover is disposed over the spike shaft to cover the sharpened tip. The spike shaft includes a hollow channel extending axially therethrough that is adapted to accommodate placement of a blunt cannula shaft concentrically therein to allow the blunt cannula to access medicine containers having unslit septums or stoppers. The spike adapter body includes axially extending grooves that accommodate blunt cannula tongues therein to form a tongue and groove attachment therebetween.
