HIGH GAS BARRIER RECEPTACLE AND CLOSURE ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a receptacle for therapeutic fluid susceptible to deterioration on exposure to a gas such as oxygen or carbon dioxide.

SOLUTION: The present invention solves the problem by providing the receptacle 30 which has walls of sheet material each including at least one layer forming a barrier essentially impermeable to such gases, and a seal sealing the walls of the receptacle 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 extending between the proximal and distal ends, and a closure 54 blocking flow through the flow passage adapted to be pierced by a tubular needle for transfer of therapeutic through the needle. The transfer tube 40 and the closure 54 are essentially impermeable to the gases.
