The device has a coupling arrangement for making flow connections to a dialysis device that is otherwise airtight. It has a ventilation valve (4) on the container wall with a ventilation opening (41) in the container wall and a sealing film (42) bridging the opening with welding or adhesive dimensioned so that the seal is broken on reaching a defined pressure difference between the air pressure outside the container and a reduced pressure inside produced by the dialysis device. |
