Fluid module, fluid system and method of cleaning fluid module

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...

AI Technical Summary

Problems solved by technology

This risk of contamination is particularly high when the fluid modules are used to alternately supply several different containers with different supply media

Here, a small amount of the first feed medium can remain in the fluid module and mix with a different feed medium that subsequently flows through the fluid module, thus rendering the cell culture unusable

[0004] In addition, contamination in the conveyed medium area of ​​the fluid module can also occur during assembly of the fluid module
