Embodiment Construction

[0026] As described in the prior art, after determining the composition of the individual concentrate, the treating physician adds the desired second concentrate (eg special concentrate 10) to the first concentrate (eg standard concentrate 9) . Here, for example, (1+44) AC-F 119 / 5 from the company Fresenius Medical Care in a 4.7-liter can was used as the first concentrate or the standard concentrate 9 . The potassium chloride concentration of the solution for hemodialysis obtained after dilution from this concentrate was 1 mmol / L. This can be increased to 2 mmol / L by metering 50 mL of special concentrate 9 with a KCl concentration of 4.2 mol / L into the standard concentrate.

[0027] The concentrate suction stick 4 is introduced into the inhomogeneous concentrate mixture thus obtained. Because the concentrate is to be removed from the container as completely as possible, the end of the concentrate pick-up stick is located at the bottom of the container. By means of inputs in...

Abstract

The invention relates to the preparation of concentrates for dialysis, the composition of which can be individually adapted to each need of the patient. To this end, the individual required volumes of 10‑500 mL of special components are added to the 3‑10 L standard concentrate in the form of highly concentrated special concentrates. Intensive mixing of the two solutions is then carried out by means of compressed air which is blown into the solution through the concentrate suction wand from a compressed air source located in the dialysis machine.

Description

technical field [0001] The invention relates to a method for the production of individual concentrates for dialysis, a device for dialysis therapy and the use of the device for carrying out the production method. Such an individual concentrate can be optimally adapted in its composition to the specific requirements of the individual patient without having to select a larger number of concentrates in the clinic. Reduce operator workload and risk of contamination by machine-automating well-mixed concentrate systems. Background technique [0002] Especially in the treatment of chronic renal failure, solutions for hemodialysis are often prepared in-line from concentrates and high-purity water using the fractionation unit of the dialysis machine. High-purity water is in most cases delivered to the dialysis machine via a central supply, while the required electrolytes are supplied to the dialysis machine by the nursing staff in the form of concentrates packaged in bags or tanks. ...
