DEVICE FOR MATERIAL EXCHANGE AND THE CULTIVATION OF CELLS

摘要

The invention relates to a device for a material and gas exchange from cells, micro-organisms, suspensions, solutions or fluids and is characterised in that flexible walls and structures, which may be linked to functions, permit internal and/or external conditioning processes. A geometrically defined arrangement of material exchange and/or gas permeable membranes form the internal structure of the device, which has a directional throughflow. The assembly is constructed such that the device possesses internal and/or external elastic properties and comprises at least one non-rigid, preferably elastic wall and can absorb pressure variations.
