Abstract

A peritoneal dialysis machine having a machine housing and having a heating receiver as well as having a plurality of solution bags is provided.The peritoneal dialysis machine furthermore has a hose set which is connected to the solution bags, wherein the plurality of solution bags are arranged in the heating pan and wherein the hose set does not have any heating bag into which the liquid draining from the solution bags runs.

First claim

The invention claimed is:

1. A peritoneal dialysis machine comprising at least one machine housing supported on a machine housing stand, at least one weighing cell arranged in or at the machine housing, at least one heating pan, a plurality of solution bags arranged in said heating pan with no heating bag being present into which liquid draining from the solution bags runs, at least one hose set which is connected to the solution bags, a weighing device having at least one weighing pan, and at least one holding apparatus connecting said weighing pan to said weighing cell, said at least one holding apparatus including at least one rod assembly which is located at a rear side of the machine housing remote from a front side of said machine housing, wherein-the weighing pan is arranged at a height of <20 cm above a floor on which the peritoneal dialysis machine stands, and wherein a spacing between the weighing pan and the heating pan in the vertical direction is in a range between 80 cm and 1.2 m.

2. A peritoneal dialysis machine comprising a machine housing supported on a machine housing stand, at least one weighing cell arranged in or at the machine housing, at least one holding apparatus, at least one weighing device having at least one weighing pan into which at least one receiving bag is arranged for receiving draining dialyzate, at least one heating pan, and at least one hose set which is connected to the at least one receiving bag, said at least one receiving bag not being in fluid communication with a waste bag in which the drained dialyzate is collected, but rather said at least one receiving bag itself forming the waste bag, said weighing pan being connected via said at least one holding apparatus to said at least one weighing cell, and said at least one holding apparatus including at least one rod assembly which is located at a rear side of the machine housing remote from a front side of said machine housing, wherein-the weighing pan is arranged at a height of <20 cm above a floor on which the peritoneal dialysis machine stands, and wherein a spacing between the weighing pan and the heating pan in the vertical direction is in a range between 80 cm and 1.2 m.

3. The peritoneal dialysis machine in accordance with claim 2 , wherein the peritoneal dialysis machine further comprises a plurality of solution bags and at least one hose set which is connected to the solution bags, the plurality of solution bags being arranged in the heating pan; and no heating bag being present into which liquid draining from the solution bags runs.

4. The peritoneal dialysis machine in accordance with claim 1 , wherein the peritoneal dialysis machine does not have an IV pole to which solution bags can be fastened.

5. The peritoneal dialysis machine in accordance with claim 1 , wherein the peritoneal dialysis machine has at least one IV pole to which one or more solution bags are fastened.

6. The peritoneal dialysis machine in accordance with claim 1 , wherein the heating pan is arranged above the machine housing and is directly connected to the machine housing.

7. The peritoneal dialysis machine in accordance with claim 1 , wherein the solution bags are arranged above one another and/or next to one another in the heating pan.

8. The peritoneal dialysis machine in accordance with claim 1 , wherein said peritoneal dialysis machine is a gravimetrically operating peritoneal dialysis machine that has no pumps for the conveying of solutions.

9. The peritoneal dialysis machine in accordance with claim 1 , wherein the hose set is configured such that it is simultaneously connected to at least two solution bags of different contents such that a mixed solution can be prepared.

10. The peritoneal dialysis machine in accordance with claim 1 , wherein the hose set is arranged such that the hose set only cooperates with exactly one fluid control valve of the peritoneal dialysis machine between a connector or connectors for at least one of said solution bags and the end of the hose set by which it is connected to the patient line.

11. The peritoneal dialysis machine in accordance with claim 2 , wherein the hose set is arranged such that the hose set only cooperates with exactly one drainage control valve of the peritoneal dialysis machine between the end of the hose set by which it is connected to the patient line and a connector for the receiving bag.

12. The peritoneal dialysis machine in accordance with claim 10 , wherein at least one fluid control valve is located at the machine housing of the peritoneal dialysis machine.

13. The peritoneal dialysis machine in accordance with claim 1 , wherein the peritoneal dialysis machine is configured with a U-shaped pedestal; and the peritoneal dialysis machine has a total height of <1.2 m.

14. The peritoneal dialysis machine in accordance with claim 1 , wherein at least one of the heating pan and the weighing pan has a base and side walls extending upwardly from the base, and wherein one or more of the side walls can be removed from the base.

15. The peritoneal dialysis machine in accordance with claim 1 , wherein the hose set is configured as disposable; and/or in that the hose set has at least two connectors for the solution bags and a connector for connection to the patient line.

16. The peritoneal dialysis machine in accordance with claim 1 , wherein the hose set has a total length of 3 m to 4.5 m.

17. The peritoneal dialysis machine in accordance with claim 1 , wherein the hose set has first line sections which extend from connectors for the solution bags to a branching piece, wherein a second line section is connected to the branching piece and extends from the branching piece to the connector for a receiving bag or for one or more lines connected thereto, and wherein a third line section is connected to the branching piece and extends from the branching piece to a connector for the patient line, wherein the first line sections each have a length in the range from 50 cm to 80 cm, wherein the second line section has a length in the range from 25 cm to 45 cm, and wherein the third line section has a length in the range from 1.9 m to 2.2 m.

18. The peritoneal dialysis machine in accordance with claim 1 , wherein the hose set is not connected to a heating bag and wherein the hose set is not connected to a weighing bag from which consumed dialyzate runs into a waste bag.

19. The peritoneal dialysis machine in accordance with claim 2 , wherein at least one drainage control valve is located at at least one machine housing support and is positioned between an end of the hose set connected to the patient line and a connector for the receiving bag, said drainage control valve being located at a height of 30 cm to 60 cm above a floor on which the peritoneal dialysis machine stands.

20. The peritoneal dialysis machine in accordance with claim 1 , wherein the weighing pan has a base and side walls extending upwardly from the base, and wherein one or more of the side walls can be pivoted relative to the base.
