Abstract: The present invention relates to a device and method for conveying fluids into the treatment unit of a medical treatment apparatus. The device and method according to the present invention are based on the fact that the fluid with which the treatment unit is supplied, circulates in a fluid circuit including the treatment unit. To balance fresh and used fluid fed to the treatment unit or conveyed from the treatment unit, a balancing unit with a balancing chamber is used, which can be incorporated into the fluid circuit including the treatment unit. It is thus possible to supply the fluid circuit continuously with fresh fluid or to carry away used fluid continuously from the fluid circuit. The supply and discharge of fresh and used fluid can take place at a different flow rate from the flow rate at which the fluid circulates in the fluid circuit via the treatment unit.

Abstract: A medical treatment apparatus, and in particular an extra-corporeal blood treatment apparatus, has a socket unit for the connection of a plug unit belonging to a device for supplying a medical fluid for the medical treatment apparatus. A filling apparatus for filling a device for supplying a medical fluid has a socket unit for the connection of a plug unit of the device for supplying a medical fluid. The device has a plug unit having means for indicating two states of operation, while the socket unit of the treatment apparatus has means for destroying the means for indicating two states of operation. When the plug unit is connected to the socket unit, the means for indicating two states of operation are destroyed, to rule out the possibility of the device being re-used. Re-use of the device is ruled out by the fact that the device cannot be re-filled with fluid.
