Abstract

The invention relates to a method and to a device for supplying a dialysis device with dialysate, and to a dialysis device comprising a device for supplying the dialysis device with dialysate. For producing dialysate, a container 13 filled with a pulverulent dialysate concentrate K is provided, the amount of dialysate concentrate in the container being set in such a way that an amount of dialysate sufficient for a specified number of dialysis treatments can be produced using the dialysate concentrate. The method according to the invention and the device according to the invention make it possible to align the amount K2 of concentrate in the container 13 and the planned consumption amount, which is dependent on the prescription from the doctor and the treatment parameters established by the machine. After the individual dialysis treatments have been carried out, it is continuously monitored whether the amount of concentrate is sufficient. It may be monitored whether the amount of concentrate is sufficient for the following treatment or for all treatments still to be carried out. If it is not sufficient, an alarm signal is generated. Otherwise, a control signal for initiating each of the next treatment cycles is generated.

Method for supplying a dialysis device with dialysate,

comprising the following method steps:
providing a container (13) that is intended for single use and is filled with a dialysate concentrate (K2) for producing dialysate, wherein the amount (M0) of dialysate concentrate in the container is set in such a way that it is possible to use the dialysate concentrate to produce an amount of dialysate sufficient for a specified number (x) of treatment cycles,
inputting treatment parameters for each treatment cycle of the predetermined number (x) of treatment cycles using an input unit (24A),
determining a provided amount (V1, V2, V3, . . . Vx) of dialysate concentrate for each treatment cycle of the specified number (x) of treatment cycles on the basis of the inputted treatment parameters using an arithmetic and evaluation unit (24),
calculating the difference in the amount (M0) of dialysate concentrate in the container and the amount (V1+V2+V3 . . . +Vx) of dialysate concentrate provided for the specified number (x) of treatment cycles, wherein
an alarm signal for generating an alarm is generated if the amount (M0) of dialysate concentrate in the container is less than the amount (V1+V2+V3 . . . +Vx) of dialysate concentrate provided for the specified number (x) of treatment cycles, and
a control signal for initiating the first treatment cycle is generated if the amount (M0) of dialysate concentrate in the container is not less than the amount of dialysate concentrate provided for the specified number (x) of treatment cycles (V1+V2+V3 . . . +Vx).

Device for supplying a dialysis device with dialysate, comprising a connecting unit (50) for connecting a container (13) that is intended for single use and is filled with a dialysate concentrate (K2) for producing dialysate, wherein the amount (M0) of dialysate concentrate in the container is set in such a way that it is possible to use the dialysate concentrate to produce an amount of dialysate sufficient for a specified number (x) of treatment cycles can be,

an input unit (24A) for inputting treatment parameters for each treatment cycle of the specified number (x) of treatment cycles,
an arithmetic and evaluation unit (24), configured in such a way that
an amount (V1, V2, V3, . . . Vx) of dialysate concentrate provided for the treatment cycle is determined for each treatment cycle of the specified number (x) of treatment cycles on the basis of the inputted treatment parameters,
the difference between the amount (M0) of dialysate concentrate in the container and the amount (V1+V2+V3 . . . Vx) of dialysate concentrate provided for the specified number (x) of treatment cycles is calculated, wherein
an alarm signal for generating an alarm is generated if the amount (M0) of dialysate concentrate in the container is less than the amount (V1+V2+V3 . . . +Vx) of dialysate concentrate provided for the specified number of treatment cycles, and
a control signal for initiating the first treatment cycle is generated if the amount (M0) of dialysate concentrate in the container is not less than the amount (V1+V2+V3 . . . +Vx) of dialysate concentrate provided for the specified number of treatment cycles.
