The invention relates to the field of containers for providing liquid dialysate concentrates for a dialysis treatment of a patient with the aid of an artificial kidney. Up to now such concentrates have been delivered mainly in rigid plastic containers as the weight of the concentrate requires a certain stability of the container. Such containers also simplify the shipping of large loads as they can easily be arranged in layers on top of each other. These rigid containers have the disadvantage that because of their rigidity they are comparatively expensive as the container walls have to be thick enough leading to higher material expenses. Furthermore, the empty containers are bulky making the further processing cumbersome. The large amount of material to be recycled or discarded adds further to the cost. The invention avoids these drawbacks by proposing a container filled with a liquid dialysate concentrate that is a self- standing bag (1) made of flexible elastomeric sheets.

La présente invention concerne des récipients destinés à fournir des concentrés de dialysat liquide pour un traitement par dialyse d'un patient à l'aide d'un rein artificiel. Jusqu'à présent, on a fourni des concentrés de ce type principalement dans des récipients en plastique rigide étant donné que le poids du concentré exige une certaine stabilité du récipient. Des récipients de ce type simplifient aussi l'expédition de grandes quantités puisqu'ils peuvent être disposés facilement en couches les uns sur les autres. Ces récipients rigides présentent l'inconvénient que, à cause de leur rigidité, ils sont comparativement chers étant donné que les parois des récipients doivent être suffisamment épaisses, ce qui entraîne des dépenses matérielles supérieures. Par ailleurs, les récipients vides sont encombrants, rendant le traitement ultérieur difficile. La grande quantité de matériau à recycler ou jeter augmente le coût. L'invention évite ces inconvénients en proposant un récipient rempli d'un concentré de dialysat liquide qui est un sac autoportant (1) fait de feuilles élastomères souples.
