Abstract

The present invention relates to a dialysis machine, in particular a peritoneal dialysis machine, wherein a dialysis treatment, in particular a peritoneal dialysis treatment, can be carried out by means of the dialysis machine in accordance with predefined and/or inputtable treatment parameters and wherein the dialysis machine has at least one setting means by means of which at least one treatment parameter can be set dynamically and/or during the treatment operation of the dialysis machine. The present invention furthermore relates to a method of operating a dialysis machine.

Claims

1. A dialysis machine (40), in particular a peritoneal dialysis machine, wherein a dialysis treatment, in particular a peritoneal dialysis treatment, can be carried out by means of the dialysis machine (40) in accordance with predefined and/or inputtable treatment parameters, and wherein the dialysis machine (40) has at least one setting means by means of which at least one treatment parameter can be set dynamically and/or during the treatment operation of the dialysis machine (40).

2. A dialysis machine (40) in accordance with claim 1, characterized in that the treatment parameter or parameters is/are the dwell time (3) and/or the instillation volume.

3. A dialysis machine (40) in accordance with claim 1, characterized in that the dialysis machine (40) has a planning means for planning a course of treatment and a monitoring means for monitoring the course of treatment, with it being able to be compared by means of the setting means whether an actual course of treatment corresponds to or differs from a planned course of treatment.

4. A dialysis machine (40) in accordance with claim 3, characterized in that at least the planned treatment duration can be predefined by means of the planning means;

and in that at least the probable treatment duration can be calculated and/or estimated by the monitoring means with reference to the previous treatment progress.

5. A dialysis machine (40) in accordance with claim 4, characterized in that a plurality of dwell times (3) are provided during the total treatment duration whose lengths are predefinable and/or predefined and stored in the planning means and wherein a correction of at least one dwell time (3) can be carried out by means of the setting means with reference to the calculation and/or estimation of the monitoring means of the probable treatment duration so that the planned treatment duration can be adhered to.

6. A dialysis machine (40) in accordance with claim 5, characterized in that the setting means has a limiting means by means of which a minimum percentage factor can be predefined which limits the maximum possible correction of the dwell time (3), with the percentage factor preferably amounting to 10% of the planned dwell time (3).

7. A dialysis machine (40) in accordance with claim 5, characterized in that the time difference between the planned and actual treatment duration can be calculated by means of the setting means;

and in that the calculated time difference can be deducted from the previously predefined dwell time (3) by means of the setting means and a dwell time (3) accordingly corrected by the calculated time difference can be set.

8. A dialysis machine (40) in accordance with claim 3, characterized in that at least one planned instillation volume, in particular all still planned instillation volumes, of dialysate can be predefined by means of the planning means;

and in that at least the instantaneously available volume of dialysate can be calculated and/or estimated by means of the monitoring means.

9. A dialysis machine (40) in accordance with claim 8, characterized in that a correction of at least on planned instillation volume and/or of all still planned instillation volumes can be carried out by means of the setting means with reference to the calculation and/or estimation of the monitoring means of the instantaneously available volume of dialysate.

10. A dialysis machine (40) in accordance with claim 9, characterized in that the setting means has a limiting means by means of which a minimum percentage factor can be predefined with limits the maximum possible correction of the planned instillation volume, with the percentage factor preferably amounting to 10% of the planned instillation volume.

11. A dialysis machine (40) in accordance with claim 9, characterized in that the volume difference between the planned and actual instillation volume or between the planned and actual instillation volumes can be calculated by means of the setting means;

and in that the calculated instillation volume or the calculated instillation volumes can be deducted from the previously predefined instillation volume or from the previously predefined instillation volumes by means of the setting means and an instillation volume or instillation volumes corrected by the calculated volume difference can accordingly be set.

12. A method of operating a dialysis machine (40), in particular of a dialysis machine (40) in accordance with claim 1, wherein a dialysis treatment, in particular a peritoneal dialysis treatment, is carried out in accordance with predefined and/or inputtable treatment parameters and wherein at least one treatment parameter can be set and/or is set at the machine side dynamically and/or during the treatment operation of the dialysis machine (40).
