[0006] Complex fluid processing and / or treatment is required in a wide range of medical technology applications. For example, during laparoscopic and open surgeries, it is necessary to extract and filter the smoke generated during the operation due to the use of high-frequency and / or laser instruments. Filtration of solid, liquid, and gaseous components in the smoke protects the patient and surgical staff from harmful gases. Furthermore, odor reduction improves working conditions.

[0007] In addition to flue gas filtration, the provision of a filtered treatment or operational gas, e.g. an insufflation gas, may be necessary.

[0008] Medical fluid processing devices may also include components or assemblies that require protection from contaminated gases or liquids, thus necessitating specific fluid filtration in this context as well. Currently, a separate protective filter unit with a filter housing and filter medium is often attached to the flue gas filter housing to protect these components or assemblies. The object of the invention is therefore to reduce the number of fluid processing devices required in medical fluid processing applications.
