1. An integrated module for fluid treatment, comprising:

  • a support element having;

    a base body;

    at least a first and at a least a second connector associated with the base body and distanced one from another;

    at least an intermediate connector interposed between said first and second connectors, distanced from said first connector and from said second connector and directly constrained to the base body, said first, second, and intermediate connectors defining pairs of connectors having differentiated interaxes there-between for engaging to corresponding pairs of counter-connectors associated with various blood treatment devices which are mountable on the support element;

    at least one blood treatment device engaged on the support element and having;

    a containment body presenting a main development axis and including a lateral surface and first and second end surfaces;

    at least one semi-permeable membrane operating internally of the containment body and defining a first chamber and a second chamber;

    a first counter-connector and a second counter-connector, both emerging from the lateral surface of the containment body and being fixed to a pair of connectors selected from the first, second, and intermediate connectors associated with the base body, at least one of the first counter-connector and the second counter-connector being placed in fluid communication with the second chamber of the blood treatment device and with respective first end portions of said pair of connectors, wherein the intermediate connector is not connected to a counter-connector of the blood treatment device;

    at least one inlet port to the first chamber associated with the first end surface and emerging axially along the development axis; and

    at least one outlet port from the first chamber associated with the second end surface and emerging axially along the development axis;

    a fluid distribution circuitry associated with the support element and cooperating with the blood treatment device, each of said pair of connectors presenting a fluid passage having a first end portion in fluid communication with a corresponding channel in a respective counter-connector on the blood treatment device and a second end portion in fluid communication with the fluid distribution circuitry the fluid distribution circuitry presenting at least one blood line having a blood withdrawal branch placed in fluid communication with the inlet port of the first chamber and emerging axially from the first end surface along the development axis and at least one blood return branch placed in fluid communication with the outlet port of the first chamber and emerging axially from the second end surface along the development axis.
