Container for medical solution, particularly for peritoneal dialysis. A large compartment (10) contains the majority of the medical solution, such as sodium bicarbonate, sodium lactate and sodium chloride. In addition, a plurality of small compartments (14, 15) are provided which contain partial quantities of the medical solution which are not compatible for long term storage with the contents of the large compartment, such as calcium ions and glucose. By mixing the contents of the first (14) or second (15) of the small compartments with the contents of the large compartment (10), a solution is obtained having 1.5 % or 2.5 % glucose and 1.0 mM or 1.6 mM calcium. By mixing the contents of both the small compartments with the contents of the large compartment, a solution is obtained having 4.0 % glucose and 2.5 mM calcium. Due to the increased ultrafiltration at high glucose concentration, these medical solutions are calcium-neutral during use as peritoneal dialysis solutions.

L'invention concerne un conteneur pour solution médicale, destiné en particulier à la dialyse péritonéale. Un compartiment de grande taille (10) contient la majeure partie de la solution médicale (par exemple, bicarbonate de soude, lactate de sodium et chlorure de sodium). En outre, plusieurs compartiments de petite taille (14, 15) sont prévus pour contenir des quantités partielles de la solution médicale, dont le stockage à long terme n'est pas compatible avec le contenu du compartiment de grande taille (par exemple, ions calcium et glucose). En mélangeant le contenu du premier (14) ou du second (15) des compartiments de petite taille avec le contenu du compartiment de grande taille (10), on obtient une solution qui renferme 1,5 ou 2,5 % de glucose et 1,0 ou 1,6 mM de calcium. En mélangeant le contenu des compartiments de petite taille avec celui des compartiments de grande taille, on obtient une solution qui renferme 4,0 % de glucose et 2,5 mM de calcium. Par suite d'une ultrafiltration accrue à forte concentration de glucose, les solutions médicales de ce type sont neutres du point de vue du calcium lorsqu'on les utilise comme solutions de dialyse péritonéale.
