Description

[0054] There are shown:

[0055] FIG. 1: a schematic view of the peritoneal dialysis system having two hoses with connector each per bag;

[0056] FIG. 2: a schematic view of the peritoneal dialysis system having one respective hose with connector per bag; and

[0057] FIG. 3: a schematic view of the peritoneal dialysis system with trolley.

[0058] FIG. 1 shows a peritoneal dialysis system in accordance with the invention in a first embodiment.

[0059] The water unit that comprises means for metering and means for treating or purifying the water is marked by reference numeral 10.

[0060] The water unit 10 is connected to a faucet 1 of a home or of a clinic, etc.

[0061] Reference numeral 20 denotes a peritoneal dialysis machine; the reference symbol P denotes a patient whose prescription is stored in the peritoneal dialysis machine 20.

[0062] Two concentrate containers of different sizes and having the concentrates K30 and K31 are marked by reference numerals 30 and 31, with the concentrate container 30 having a volume of 15 l and the concentrate container 31 having a volume of 5 l.

[0063] Both are prefilled with a concentrate K30, K31 that is diluted with water from the unit 10.

[0064] As can be seen from FIG. 1, each of these concentrate containers 30, 31 has a first hose S1 having a first connector K1 and a second hose S2 having a second connector K2, with the hoses S1 serving the supply of water from the unit 10 into the bags 30, 31 and the hoses S2 the drainage of the diluted concentrate or the completed dialysis solution from the bags 30, 31 to the peritoneal dialysis machine 20. A respective one-way ultrapure filter 11 is located in the hoses S1.

[0065] The connectors K1 and K2 each include barcodes B1 and B2 respectively.

[0066] The barcodes B1 include information that permits conclusions on the volume or mass of water that is to be filled into the bags 30, 31. The water unit 10 reads this information and meters a corresponding amount of water into the bags so that the desired concentration of the individual substances is present in the bags.

[0067] As soon as this is the case, the solution can be used for use in the peritoneal dialysis machine 20. The peritoneal dialysis machine 20 reads which solution it is from the barcode B2 of the connector K2.

[0068] It is possible by the present invention to dispense with the delivery of solution bags that contain the completed dialysis solution. The provision of concentrate bags or concentrate containers whose contents are only diluted to the desired concentrations on site is rather sufficient.

[0069] The peritoneal dialysis machine 20 likewise has one or more receivers for standard connectors so that a completely filled standard solution bag 33 can also be connected and used, as is shown in FIG. 1.

[0070] FIG. 2 shows an embodiment in which the concentrate containers only have one hose S3 that is designed with a connector K3 having a barcode B3. In another respect, parts that are the same or have the same function are marked by the same reference numerals as in FIG. 1.

[0071] The connector K3 is introduced into a receiver of the peritoneal dialysis machine 20 and is thus not in direct communication with the water unit 10.

[0072] The water unit 10 comprises a prefilter and an RO unit 11, a pump such as an impeller pump 12 and filters 13 connected downstream thereof. The water unit 10 is in communication with the peritoneal dialysis machine 20 via a hose 40 or via another line. A further filter 41, e.g. an 0.2 filter, is located in this hose 40.

[0073] The peritoneal dialysis machine 20 reads the barcodes B3 and reports what amount of water is to be metered to the water unit 10. The water unit 10 delivers this amount of water to the peritoneal dialysis machine 20 and from it into the concentrate containers 30, 31. After the dilution and dissolving into the concentrate containers 30, 31 has taken place, the solution is delivered to the peritoneal dialysis machine or is conveyed from it to the patient, e.g. by means of one or more pumps. Reference numeral 60 marks a safety chamber in the concentrate container 30.

[0074] The barcodes B1 and B3 comprise information that indicates the type of solution to be prepared or the type of concentrate and the quantity of the water to be added. Despite the same reference symbol B1, the barcode B1 of the bag 30 optionally has a different piece of information than the barcode B1 of the bag 31. This applies accordingly to the barcodes B2 and B3.

[0075] The peritoneal dialysis system can be used as a batch-type system that prepares the solutions for the respective treatment batch-wise.

[0076] It is conceivable to move the peritoneal dialysis machine or the peritoneal dialysis system as a whole to the patient.

[0077] The peritoneal dialysis machine can be moved on a trolley T from a filling station or from the water unit to the patient.

[0078] FIG. 3a) shows the peritoneal dialysis machine 20 and the water unit as a movable peritoneal dialysis system, wherein the peritoneal dialysis machine 20 stands on top of the water unit 10.

[0079] FIG. 3b) shows the peritoneal dialysis machine 20 on a trolley T and independently of the water unit 10 that is configured in this case as a separate unit separated from the peritoneal dialysis machine 20.
