Patent ID: 7507217

Claim:
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 ).
