DISPOSABLE PUMPING APPARATUS BASED ON FLEXIBLE VESSELS IN PRESSURIZED CONTAINERS

摘要

An apparatus is provided for intended use in pumping a fluid under sterile conditions. In one embodiment, a first rigid container is internally pressurized to pump fluid through a first flexible vessel within the rigid container. In another embodiment, first and second containers are provided, each for receiving flexible vessels that create independent pumping chambers upon the selective or periodic internal pressurization of the containers. Related aspects and methods are also provided.
