摘要

The invention relates to a medical treatment device (2) in particular an extracorporeal blood treatment device comprising a socket unit (B) for connecting a plug unit (A) of a device (1) for providing a medical liquid for the medical treatment device and to a device (3) for filling a device (1) for providing a medical liquid comprising a socket unit (B ) for the connection of a plug unit (A) of the device (1) for providing a medical fluid. The invention further relates to a device (1) for providing a medical liquid. The plug unit (A) of the device (1) for providing a medical liquid comprises means (86) for signaling two operating states while the socket unit (B) of the treatment device (2) comprises means (88) for destroying the means (86) for signaling two operating states. When the plug unit (A) is connected to the socket unit (A) the means for signaling two operating states are destroyed in order to exclude the reuse of the device (1) for providing a medical liquid. The reuse of the device is prevented in that the device cannot be refilled with liquid.
