The present invention relates to a multi-chamber bag. In all embodiments at least two different concentrates can be included separately in powder form, liquid form or semi-liquid slurry form for dissolution in a fluid in the multi-chamber bag. The present invention also relates to the use of the multi-chamber bag in haemodialysis or peritoneal dialysis or a haemodialysis or peritoneal dialysis device, in particular as a container for a dialysis fluid in a haemodialysis or peritoneal dialysis device.


The invention relates to the field of connectors for connecting a container with a fluid preparation device for preparing a fluid, in particular a container with a concentrate for the preparation of dialysis fluid. In order to simplify the handling during both the manufacturing process of such containers and the connection of such containers to the fluid preparation devices, the invention proposes a design of a connector (1) for connecting a first and second fluid line of the container with a third and fourth fluid line of the fluid preparation device with two lateraly spaced-apart mounting means (2, 4) which each incorporate one of two orifices (3, 5) terminating the first and second fluid lines. The invention also concerns a corresponding container and fluid preparation device.

The present invention relates to a method for estimating the duration of a peritoneal dialysis treatment, wherein the estimation of the duration of treatment is carried out on the basis of an ideal duration of treatment and the ideal duration of treatment is increased by one or more delay values, said delay values being dependent on one or more device-specific and/or patient-specific and/or method-specific parameters.


The invention relates to a disposable for extracorporeal blood treatment, which disposable comprises a blood admission line, a separator, a blood return line and a plasma line, wherein the disposable comprises at least two interfaces for the addition of citrate, wherein a first interface is arranged in the blood admission line and a second interface is arranged in the plasma line. The invention further relates to a device for carrying out extracorporeal blood treatment, which device has a disposable according to the invention and a citrate source, the latter being coupled to the first interface or to the second interface. The invention further relates to a method for checking the correct attachment of a citrate source to a liquid-conveying line of a device for carrying out blood treatment, wherein an overpressure is generated in the area of the attachment by way of a pump arranged in the citrate source, the increase and/or subsequent decrease of this pressure is detected and, on the basis of the detected pressure increase or pressure decrease, and following a routine stored in the device, a conclusion is drawn concerning the correct attachment of the citrate source.
