Abstract

A dry concentrate bag for preparing a dialysis fluid comprising one or more plastic films defining two welded together to define a housing space for the dry concentrate; a dry concentrate housed within the housing space; an inlet portion placed in correspondence of a bottom area in use conditions of the dry concentrate bag and comprising an inlet port for receiving a fluid; an outlet portion placed in correspondence of a top area in use conditions of the dry concentrate bag and comprising an outlet port for letting the fluid mixed with the dry concentrate to leave the housing space. The inlet portion comprises a first and a second inclined welding lines both emerging from the inlet port and defining a lower cone portion of the housing space, the inlet port being placed at the lowest point of the lower cone portion, wherein the outlet portion comprises a third and a fourth inclined welding lines both converging to the outlet port and defining an upper cone portion of the housing space, the outlet port being placed at the highest point of the upper cone portion.
