Problems solved by technology
Such an additional opening or even just an additional connection poses an additional risk in terms of sterilization
Furthermore, this interface must be controlled from time to time in addition to the other components of the sterile barrier, which increases the cost and the effort involved

Embodiment Construction
[0059] The following will refer to figure 1 and figure 2 A first embodiment of a filter system 2 according to the invention is described.
[0060] figure 1 The filter system 2 is shown in a cold state. The filter system 2 comprises a disc-shaped filter element 4 which is firmly framed or pressed in an annular holder 6 and a sealing ring 8 . A sealing ring 8 is arranged in the outer region of the holder 6 , which corresponds to the outer diameter of the filter element 4 . In other words, the diameter of the sealing ring 8 approximately corresponds to the diameter of the filter element 4 . The holder 6 is accommodated together with the filter element 4 and the sealing ring 8 in the pot lid 10 . A surrounding peripheral wall 11 extends from the circular cover part 9 of the cover 10 . Cap 10 may be attached to sterile container base 12 of sterile container 14 (eg, by clamping, screwing, or turning). For this purpose, a groove 16 is provided in the sterile container base 12...

The invention relates to a gas-permeable filter system (2; 2') for a sterile container (14), comprising a filter element (4; 46); a seal portion (8) which is designed to sealingly surround a gas exchange opening (24) provided in a sterile container wall section (12) in such a manner that the seal portion rests against the sterile container wall section (12) of the sterile container (14) so that asterile flow path is formed through the gas exchange opening (24) and the filter element (4; 46); at least one temperature-sensitive adjusting section (28; 38) which compulsively releases at least theseal portion (8) from the sterile container wall section (12) when a specified temperature is reached or exceeded such that a non-sterile flow path is formed which allows fluid to be supplied or discharged via the gas exchange opening (24) while bypassing the filter element (4; 46); and a sterile container (14), in particular for receiving and storing surgical instruments or surgical material ina sterile manner, comprising a receiving space (54) made of a sterile container base (12) and sterile container walls (52) and comprising a sterile container cover for closing the receiving space (54), wherein at least one filter system (2; 2') is preferably secured to the sterile container base (12).
Description
technical field [0001] The present invention relates to a gas permeable filter system for a sterile container and a sterile container comprising the filter system. Background technique [0002] In most clinical protocols and operations, it is imperative to ensure the sterility of the instruments and / or other auxiliary equipment used. For this reason, sterile containers (also called sterile containers) are used, which are loaded / filled with medical instruments, for example. Under load, the sterile container is then heated in an autoclave for a specified period of time to a specified sterilization temperature until any microorganisms adhering to the medical device have been killed. [0003] Heating the container and its contents with steam during steam sterilization leads to the formation of condensation within the container, which prolongs the drying time of the sterile material, or in the worst case results in moist sterile material even after removal. Drain openings in st...
