## Abstract

The present invention relates to an apparatus for providing a dialysis solution and preferably a peritoneal dialysis solution comprising a reception container that can accommodate a solution volume that is intended for at least two treatments, wherein the apparatus has a plurality of extraction ports for extracting the dialysis solution from the reception container.

## Claims

### Claim 1

An apparatus containing a dialysis solution or a dialysis solution concentrate, useful in peritoneal dialysis, comprising a reception container that can accommodate a solution volume which is intended for at least two treatments,
characterized in that
the apparatus has a plurality of extraction ports for extracting the dialysis solution or the dialysis solution concentrate from the reception container and the extraction ports are individually sealed by airtight sheaths, with provision being made that a number of sheaths corresponding to the number of extraction ports is present, with an innermost sheath surrounding an extraction port.

### Claim 2 (depends on 1)

An apparatus in accordance with claim 1, characterized in that a valve and a drainage port are associated with each extraction port.

### Claim 3 (depends on 1)

An apparatus in accordance with claim 1, characterized in that the apparatus has a main extraction line connected to the reception container and from which a plurality of single extraction lines having the extraction ports lead off.

### Claim 4 (depends on 3)

An apparatus in accordance with claim 3, characterized in that respective closing means by which the single extraction lines can be closed are arranged in the single extraction lines.

### Claim 5 (depends on 4)

An apparatus in accordance with claim 4, characterized in that the closing means are configured such that they close automatically on or after a decoupling of the single extraction line from a patient.

### Claim 6 (depends on 3)

An apparatus in accordance with claim 3, characterized in that the single extraction lines branch off from the main extraction line at different branch points that are distributed over a length of the main extraction line.

### Claim 7 (depends on 6)

An apparatus in accordance with claim 6, characterized in that respective closing means are arranged in the main extraction line between branch points of the single extraction lines that follow one another and with which the main extraction line can be closed.
