A device for exchanging and/or docking functional modules (1, 2), and used for the extracorporeal circulation of bodily fluids, is provided. Each functional module (1, 2) includes at least one conduit (3; 4) comprising an inlet (5; 7) and an outlet (6; 8). The aim of the invention is to exchange the functional modules of an extracorporeal circuit as rapidly as possible, without detaching tubular connections and without having to establish a new connection. The invention is provided with elements (9, 10; 11, 12) for connecting the conduit (3) of a first functional module (1) to the inlet (5) and the outlet (6) of a second functional module (2). The connection is established in such a way that the first functional module (1) is bypassed by means of the second functional module (2) to maintain the flow and the bodily fluid is diverted through the second functional module (2).

The invention claimed is: 1. A device for changing and/or docking of first and second functional modules (1 and 2) for the extra corporeal circulation of body fluids, each functional module (1 and 2) provided with at least one body fluid flow permeable (3 and 4) with an inlet (5 and 7) and an outlet (6 and 8), the device comprising: at least one connecting element (9, 10; 11, and 12) for connecting the conduit (3) of the first functional module (1) to the inlet (5) and the outlet (6) of the second functional module (2) so that the first functional module (1) is bypassed by a fluid-mechanical bridging through the second functional module (2) to maintain the flow of the body fluid, wherein the connecting element (9, 10; 11, and 12) includes a valve connection for the inlet (5) and the outlet (6) of the second functional module (2) and a designated portal in the conduit (3) of the first functional module (1), the valve connection protruding outwardly at the inlet (5) and the outlet (6) of the second functional module (2) to an extent that the valve connections intervene in the respective portals of the first functional module (1) during a mounting of the second functional module (2) on the first functional module (1), the valve connections interacting during the connecting of the first and second functional modules (1 and 2) in each of the respective portals so that the functional circulation of the first functional module (1) is by-passed, wherein the second functional module (2) for connecting with an additional functional module (18) is provided with portals (13 and 14), each of the portals containing an angled branch of the associated conduit (3 and 4) so that the connecting valve closes an axonal branch (19) of the conduit (3 and 4) during a penetration into the assigned portal and diverts the flow of the body fluid into at least one of the second functional module (2) and the functional module (18). 2. The device according to claim 1, wherein the inlet (5) and the outlet (6) of the second functional module (2), each provided with a valve connection which, upon connecting the functional module (1 or 2) with the correspondingly designed portals for preparation of a leak-tight connection, the valve connection can interact with the permeable body fluid. 3. The device according to claim 1, wherein each of the portals is sealed germfree at the outward pointing end in an unused condition by means of a permeable membrane (15). 4. The device according to claim 1, wherein each of the portals is sealed germ free at the outward pointing end by means of a valve (16). 5. The device according to claim 1, wherein each of the portals is maintained germ free or sterile by means of a protective cap or foil. 6. The device according to claim 1, wherein at least one of the outlet (6) of the second functional module (2) and the outlet of the additional functional module (18) is provided with a priming valve (17) for evacuation of air from, or for filling with a fluid, at least one of the second functional module (2) and the functional module (18). 7. The device according to claim 1, wherein each portal contains a valve mechanism by means of which the flow of the body fluids is diverted into at least one of the second functional module (2) and the functional module (18) after the penetration of the valve connections. 8. A device for changing and/or docking of first and second functional modules (1 and 2) for the extra corporeal circulation of body fluids, each functional module (1 and 2) provided with at least one body fluid flow permeable (3 and 4) with an inlet (5 and 7) and an outlet (6 and 8), the device comprising: at least one connecting element (9, 10; 11, and 12) for connecting the conduit (3) of the first functional module (1) to the inlet (5) and the outlet (6) of the second functional module (2) so that the first functional module (1) is bypassed by a fluid-mechanical bridging through the second functional module (2) to maintain the flow of the body fluid, wherein the connecting element (9, 10; 11, and 12) includes a valve connection for the inlet (5) and the outlet (6) of the second functional module (2) and a designated portal in the conduit (3) of the first functional module (1), the valve connection protruding outwardly at the inlet (5) and the outlet (6) of the second functional module (2) to an extent that the valve connections intervene in the respective portals of the first functional module (1) during a mounting of the second functional module (2) on the first functional module (1), the valve connections interacting during the connecting of the first and second functional modules (1 and 2) in each of the respective portals so that the functional circulation of the first functional module (1) is by-passed, wherein the second functional module (2) for connecting with an additional functional module (18) is provided with portals (13 and 14), each portal containing a valve mechanism by means of which the flow of the body fluids is diverted into at least one of the second functional module (2) and the functional module (18) after the penetration of the valve connections.
