Patent number: 7914900Abstract: The present invention provides a receptacle (30) for a therapeutic fluid susceptible to deterioration on exposure to a gas such as oxygen or carbon dioxide. The receptacle (30) has walls of sheet material each including at least one layer forming a barrier essentially impermeable to such gas, and a seal sealing the walls together in a region thereof. A transfer tube (40) is sealed in the seal having a proximal end in the receptacle (30), a distal end accessible from outside the receptacle (30), a flow passage (56) extending between said proximal and distal ends, and a closure (54) blocking flow through the flow passage (56) adapted to be pierced by a tubular needle for transfer of therapeutic through the needle. The transfer tube (40) and closure (54) are essentially impermeable to said gas.Type: GrantFiled: August 21, 2008Date of Patent: March 29, 2011Assignees: Baxter International Inc., Baxter Healthcare S.A.Inventors: Sidney T.
