1. A fluid flow device comprising a plurality of fluid flow functional modules each fastened on a respective individual base comprising:
two parallel lateral faces via which the bases are adapted to be placed against one another in such a manner that when the bases are placed against one another, two of the bases each have one lateral face that is free;
a primary fluid transport channel passing through the base to open out in its two lateral faces in identical relative positions;
a front face along which the module extends so as to couple an inlet channel of said module with a secondary channel extending inside the base from the front face and opening out in the primary channel;
a check valve having both an open state and also a closed state in which the check valve closes the secondary channel when the base is not provided with a module; and
a top face in which there extends a tertiary channel opening out in the primary channel;
the device including a fastener for fastening the bases to one another, a leaktight coupler for coupling primary channels with one another, a leaktight coupler for coupling an end of the primary channel opening out in one of the free lateral faces to a source of fluid under pressure in order to feed the modules, and a leaktight coupler for coupling the end of the tertiary channel opening out in the top face of the base to a source of fluid under pressure in order to feed the module.
