INFUSION BAG PRESSURIZING CONTAINER AND INFUSION BAG PRESSURIZING DEVICE

摘要

[Problem] To provide an infusion bag pressurizing container with which a fixed delivery flow rate can be obtained during infusion. [Solution] An infusion bag pressurizing container 10 according to a first embodiment has a connection part 12 to connect to a boosting means that raises the pressure of a pressure transmission fluid 11 that pressurizes an infusion bag 1 above atmospheric pressure. In the infusion bag pressurizing container 10, an infusion bag pressurizing means, which compresses the infusion bag 1 by the pressure transmission fluid 11 having raised pressure, serves as a pressure intermediary container which is composed of a contact film 14 that contacts the infusion bag 1 and transmits pressure and an outer film 15 that seals the pressure transmission fluid 11 pressing the contact film 14. The infusion bag pressurizing container 10 includes a contact film surface tension reducing structure that reduces the tension of the film surface of the contact film 14.
