Patent ID: 7475916

Claim:
A fluidic system having at least one liquid line and a coupling device for liquid-tight coupling the at least one liquid line to a surface of the fluidic system, said fluidic system coupling device comprising: at least one sealing device having at least one bushing receiving an end region of the at least one liquid line and having a first sealing surface in contact with an external surface of the fluidic system, an end of the at least one liquid line being laterally enclosed by the first sealing surface and pointing toward an opening in the external surface, and a clamping device having a fluidic block, a holding plate and at least one hollow plunger forming a receptacle for at least a part of the at least one bushing, wherein the clamping device presses the bushing onto the fluidic system without the clamping device contacting the fluidic system, so that the first sealing surface produces a liquid-tight connection with the external surface, wherein the at least one hollow plunger is situated so as to be movable in relation to the external surface, the at least one bushing has an external shape that is complementary to and interacts with an internal shape of the at least one hollow plunger of the clamping device in such a way that a force directed toward the external surface of the fluidic system is exerted on the at least one bushing using the at least one hollow plunger, and the at least one bushing has a projection forming the first sealing surface and an engagement surface for the clamping device, wherein the at least one bushing has an internal hollow channel removably receiving the end region of the at least one liquid line, the internal hollow channel forming a second sealing surface and the at least one sealing device being able to be pressed against the end region of the at least one liquid line using the hollow plunger in such a way that the second sealing surface produces a liquid-tight connection with the surface of the end region, and wherein the fluidic block is pressed onto the holding plate using a bayonet connector interengaging the holding plate.
