Embodiment Construction

[0058] figure 1 A fluid system 10 according to the invention is shown schematically, which has a plurality of fluid modules 12 according to the invention. The individual fluid modules 12 are fluidically connected to one another.

[0059] Each fluid module 12 comprises a valve node 14 which has four flow-spaced fluid channels 16 , 17 , 18 , 19 which open into a central fluid chamber 20 .

[0060] The fluid channels 16, 17, 18, 19 and the central fluid chamber 20 are constructed in a base body 22, which is in figure 2 can be seen in .

[0061] The fluid module 12 also includes four individual valves 24 , 25 , 26 , 27 which serve to block or release the fluid flow through the assigned fluid channels 16 , 17 , 18 , 19 .

[0062] One of the individual valves 24 , 25 , 26 , 27 is part of a connection module 28 which is fastened at a connection point 30 on the valve node 14 . The corresponding individual valve 27 thus forms a connecting valve. The isolation between the valve no...

Abstract

The invention relates to a fluid module (12) having a valve node (14) with a main body (22) delimited by an outer side (56). The main body has a central fluid chamber (20) and at least four fluid channels which are fluidically separated from one another and which each open into the same, at least two valve connections being provided on the outer side (56), a connection point (30) is provided on the valve node, to which a connection module (28) is fastened, in which connection module a connection channel (34) is formed, which is fluidically connected to one of the fluid channels in the valve node. the coupling module comprises a coupling valve (27) for selectively opening and closing the connecting channel. The invention further relates to a fluid system having at least two fluid modules and to a method for cleaning a fluid system or a fluid module.

Description

technical field [0001] The invention relates to a fluid module with a valve node, a fluid system with at least two fluid modules and a method for cleaning a fluid module or a fluid system. Background technique [0002] Fluid modules or fluid systems are mainly used for coupling and disconnecting processes in hygienic applications. One possible application example is the provision of a supply medium, for example liquid culture medium, for a cell culture in a vessel or the removal of a product grown with the aid of the cell culture from the vessel. Such a process may last several weeks, in which the container containing the cell culture must be repeatedly connected to the fluid system in order to supply the cell culture. [0003] Contaminants may occur in the fluidic module during multiple couplings and disconnections of containers, which can lead to waste if they reach the cell culture or mix with the finished product. In particular the transported media can become contamin...
