Flexible medical container with selectively enlargeable compartments and method for making same

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. The seals are ruptured by manipulation of the container to thereby mix the contents together for delivery through standard IV arrangement to a patient.

JK Thorsens Patentbureau AS, 0134 Oslo (54) Designation Flexible medical container with selectively expandable compartment and method for its preparation (57) Summary

Flexible container (10) for storage and administration of drug solutions.

The container comprises a transparent front sheet (12) made of a flat layer of a polymer and an opposing rear sheet (14). The backing sheet is made of a flat laminate layer.

The front and back sheets are sealed to one another along a common circumferential edge (16) to form a casing. The casing is made of materials that have good properties in forming oxygen and moisture barrier, enabling the thermoplastic container to be stored for long periods without degrading the contents. The casing is inflated with a pressurized gas to permanently stretch the front and rear sheets outward, thereby increasing the volume capacity of the container. An alternative embodiment of the container comprises a plurality of compartments (22, 23, 24) separated by peelable seals (25, 26) to contain a diluent and a medicament. The seals are broken by manipulating the container, thereby mixing the contents together for delivery via a standard intravenous arrangement to a patient.
