Abstract

The supply device for dialysis apparatuses, comprising a permeate line and at least one concentrate line for supplying permeate and dialysis concentrate(s) to a dialysis apparatus to be mixed so as to obtain dialysis liquid, and comprising a waste water line for discharging waste water out of the dialysis apparatus, is characterized in that the waste water line is in communication with a substantially funnel-shaped outlet container into which the waste water falls in a free fall, thereby impinging on an inclined wall section of the outlet container. Virtually no noise is created that would be noticed by a patient, and a pivotable door is preferably arranged at the outlet container for permitting the taking of samples in an easy way from the outlet container by means of small test rods.

Claims

1. A supply device for dialysis apparatuses, comprising a permeate line and at least one concentrate line for supplying permeate and dialysis concentrate(s) to a dialysis apparatus to be mixed so as to obtain dialysis liquid, and comprising a waste water line for discharging waste water out of the dialysis apparatus,

characterized in

that the waste water line is in communication with a substantially funnel-shaped outlet container (1) in which the waste water falls in a free fall, thereby impinging on an inclined wall section (6) of the outlet container (1).

2. The supply device according to claim 1,

characterized in

that the outlet container (1) is composed of a funnel (2), an upper lid (3) and a pivotable door (4).

3. The supply device according to claim 2,

characterized in

that at least one waster-water inlet nozzle (11) passes through the lid (3).

4. The supply device according to claim 3,

characterized in

that the at least one waste-water inlet nozzle (11) comprises a lower rim section with at least one pointed projection (12).

5. The supply device according to claim 4,

characterized in

that the rim section comprises two opposite pointed projections (12) between which the rim section ends in concave rim edges (13).

6. The supply device according to any one of claims 2 to 5,

characterized in

that the lower end portion of the funnel (2) has molded thereon webs that transversely extend across the interior and on which a siphon cleaning tablet can be placed.

7. The supply device according to claim 1,

characterized in

that at least one permeate block (22) and at least one concentrate block (23) that comprise the associated bores are inserted into the permeate line and into the at least one concentrate line.

8. The supply device according to claim 7,

characterized in

that all permeate blocks (22) and all concentrate blocks (23) are provided with supply connections (24) configured as hose-nozzle or plug-type connections, and with coupling means (26, 27, 28).

9. The supply device according to claim 7,

characterized in

that the permeate line, the concentrate lines as well as the permeate blocks (22) and concentrate blocks (23) are arranged in a supply channel (20) from the sidewall (22a) of which the coupling means (26, 27, 28) are projecting.

10. The supply device according to claim 9,

characterized in

that the lid (3) of the outlet container (1) is mounted on the bottom side of the supply channel (20), and that the permeate block (22) comprises at least one separate waste-water line bore with a waste-water coupling means (26) passing through the sidewall (22a) of the channel, with the waste-water line bore being connected to the at least one waste-water inlet nozzle (11).
