Abstract

A method provides for the production of a concentrate for dialysis, the composition of which can be adapted individually to the respective needs of the patient. The special components required individually are added in the form of highly concentrated special concentrates with a volume of 10-500 mL to 3-10 liters of standard concentrate. The two solutions are then mixed thoroughly by compressed air, which is blown through a concentrate intake rod into the solution from a compressed air source in the dialysis machine.

Claims (27)

1. A method of producing an individual liquid concentrate in a container for dialysis from a first liquid concentrate and a second liquid concentrate with a device that includes a dialysis machine having a compressed air source, a concentrate line, a compressed air line between the concentrate line and the compressed air source, and a concentrate intake rod that is connected to the concentrate line, said method comprising:

thoroughly mixing the first liquid concentrate and the second liquid concentrate in the container by introducing compressed air, the compressed air being introduced into the container from the compressed air source in the dialysis machine through the compressed air line, the concentrate line, and the connected concentrate intake rod.

2. The method according to claim 1 , wherein the first liquid concentrate is a standard concentrate for a bicarbonate dialysis.

3. The method according to claim 2 , wherein the standard concentrate is an acidic concentrate or a basic concentrate for the bicarbonate dialysis.

4. The method according to claim 2 , wherein the standard concentrate is supplied in an amount of 3-10 liters.

5. The method according to claim 1 , wherein the second liquid concentrate is a special concentrate.

6. The method according to claim 5 , wherein the special concentrate is supplied in an amount of 5-200 mL.

7. The method according to claim 6 , wherein the special concentrate is supplied in an amount of 10-50 mL.

8. The method according to claim 5 , wherein the special concentrate includes potassium, sodium, calcium, magnesium phosphate, glucose, vitamins, amino acids, and/or trace elements.

9. The method according to claim 5 , further comprising other special concentrates.

10. The method according to claim 1 , wherein the compressed air source is a compressor.

11. The method according to claim 10 , further comprising a valve located between the compressed air line and the concentrate line, and a step of opening the valve to supply the compressed air to the concentrate line.

12. The method according to claim 1 , wherein the step of mixing includes introducing the compressed air into the first liquid concentrate and the second liquid concentrate in the container over a period of 5-60 seconds.

13. The method according to claim 1 , wherein the compressed air is supplied in an amount of 1-10 liters of air per minute.

14. The method according to claim 1 , further comprising a step of sterile-filtering the compressed air before introducing the compressed air into the concentrate line.

15. The method according to claim 1 , further comprising a control unit, and wherein control and regulating processes for performing the method are associated with operation of the control unit.

16. A device for performing a dialysis treatment, comprising:

a portioning unit for online supply of a first liquid concentrate and a second liquid concentrate for the dialysis treatment, the portioning unit including

a liquid concentrate line,

a concentrate intake rod connected to the liquid concentrate line,

a source of compressed air for mixing of the first liquid concentrate and the second liquid concentrate,

a compressed air line from the compressed air source to the liquid concentrate line connected to the concentrate intake rod, and

a control unit configured to control and regulate processes associated with performing the dialysis treatment, including the mixing of the first liquid concentrate and the second liquid concentrate by introducing the compressed air through the compressed air line, the liquid concentrate line, and the connected concentrate intake rod.

17. A method of producing an individual liquid concentrate in a container for dialysis from a first liquid concentrate and a second liquid concentrate with a device that includes a dialysis machine having a compressed air source, a concentrate line, a compressed air line between the concentrate line and the compressed air source, and a concentrate intake rod that is connected to the concentrate line, said method comprising the steps of:

combining the first liquid concentrate and the second liquid concentrate in the container; and

mixing the combined first liquid concentrate and second liquid concentrate in the container by introducing compressed air so as to produce a homogeneous individual liquid concentrate, the compressed air being introduced into the container from the compressed air source through the compressed air line, the concentrate line, and the connected concentrate intake rod.

18. The method according to claim 17 , wherein the step of combining includes providing the first liquid concentrate in the container, and adding the second liquid concentrate thereto.
