Abstract: The present invention concerns cartridges adapted to provide a solution for medical use such as a dyalysis solution by dissolving a plurality of substances in powder form in at least one liquid. The cartridge according to the invention comprises a container including a lateral wall, a bottom wall unitary with the lateral wall, the lateral and bottom walls delimiting a main volume, a central nucleus unitary with the bottom wall, the height of the central nucleus being substantially equal to that of the lateral wall to define an annular volume in the main volume, at least two separation walls imperviously unitary with the bottom wall, with the interior surface of the lateral wall and with the exterior surface of the central nucleus to delimit two secondary volumes in the annular volume, and at least two fluid connections adapted to connect the exterior of the container with the two secondary volumes.

Abstract: A container for quick connection and disconnection to a dialysis generator, the container having a substantial amount of solid compound for extemporaneous and continuous preparation of dialysate obtained from dissolution of a concentrate and/or from the solid compound in treated water. A conduit leads the water from an inlet orifice to the container, where the treated water passes through the solid compound and therethrough to and outlet orifice and into the dialysis generator. The water may be directed through a conduit within the container or through a conduit outside the container. The inlet and the outlet orifices may be provided with a micron filter.

Abstract: A device for the extemporaneous and continuous preparation of a solution for dialysis by the dissolution of several substances in powder form in water. The device includes a number of independent cartridges each containing a salt of a substance necessary for the preparation of the dialyzate, such as sodium chloride, potassium chloride, calcium chloride, magnesium chloride, and sodium bicarbonate.
