1. A method of loading a peritoneal dialysis device, which has a device control, a weighing scale, and a user interface, wherein at least one fluid-filled container is connected to a corresponding interface of the device, characterized in that
a plurality of the fluid-filled containers are placed sequentially onto the scale, the weight is measured as each container is placed on the scale, and each measured value is compared with (i) a desired value having predefined tolerance limits stored in the device control and (ii) a therapy prescription stored in the device control,
it is displayed at the user interface whether the measured value corresponds to (i) the desired value or lies within the predefined tolerance limits and (ii) the therapy prescription,
a plausibility check is performed by the medical device with respect to the volumes of the containers placed on and with respect to the therapy prescription, wherein in the plausibility check a query is made whether a dialysis solution exists which corresponds with the container combination used,
as the plurality of fluid filled containers are weighed, each weight of an individual bag is used as a new reference point and total accumulated weight of the plurality of fluid filled containers is determined, and the determined value is compared with the therapy prescription stored in the device control,
it is displayed at the user interface whether the determined value corresponds to the therapy prescription,
a further plausibility check is performed by the medical device with respect to the total volume of the containers placed on and with respect to the therapy prescription, and
a connection of the containers and/or subsequent steps are blocked by the device control if either (a) the measured value (i) does not correspond to the desired value or does not lie within the predefined tolerance limits and/or (ii) does not correspond to the therapy prescription or (b) the determined value does not correspond to the therapy prescription.
