The invention relates to a multi-chamber bagfor medical purposes which is formed by films, in particular flexible films, that are arranged against one another, are made of an at least partially transparent material and are interconnected in a liquid-tight manner using at least one non-separable seam, the bag being divided into at least two chambersA,B by at least one separable seam, by means of which the films arranged against one another are interconnected in a liquid-tight manner. The multi-chamber bag according to the invention is characterised by at least one visually perceptible structurethat signals the state of the at least one separable seamand can be easily optically detected. Using this visible structure, the user can immediately identify whether the seamis open or closed. The structure is composed of structural elementswhich the filmsarranged against one another comprise in the region of the separable seamand are in a predetermined spatial arrangement relative to one another such that the structural elements in the region of the separable seam complement one another to form the structure signalling the state of the separable seam when the separable seam is closed, such that the films in the region of the separable seam lie against one another in a predetermined orientation, and do not complement one another to form the structure signalling the state of the separable seam when the separable seam is open, such that the films in the region of the separable seam do not lie against one another in a predetermined orientation, meaning that the predetermined spatial arrangement of the structural elements relative to one another in the region of the separable seam no longer exists.

The present invention relates to a dialysis solution containing bicarbonate, calcium and phosphate, wherein the dialysis solution contains phosphate having a concentration in the range from up to 0.4 mmol/l, preferably in the range from up to 0.375 mmol/l, or in the range from up to 0.25 mmol/l, and particularly preferably in the range from up to 0.2 mmol/l.

Dialysis solution

This document relates to bi-carbonate-buffered dialysis solutions with physiological phosphate content and increased stability. The solutions include an organic ester of phosphoric acid, calcium ions and/or magnesium ions, and optionally additional electrolytes, buffers and glucose in physiologically effective concentrations.
