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...

Abstract

The invention relates to a gas permeable filter system (2; 2') for a sterile container (14), comprising: a filter element (4; 46); A gas exchange opening (24) in the sterile container wall portion (12) in such a way that the sealing portion rests against the sterile container wall portion (12) of the sterile container (14) such that a gas exchange opening (24) through the gas exchange opening (24) is formed and the sterile flow path of the filter element (4; 46); at least one temperature-sensitive adjustment part (28; 38) that forcibly releases at least the sealing part ( 8) so as to form a non-sterile flow path that allows fluid to be supplied or discharged through the gas exchange opening (24) while bypassing the filter element (4; 46); Receive and store surgical instruments or surgical materials in an aseptic manner, including a containment space (54) made of a sterile container base (12) and a sterile container wall (52), and including a closure for closing the containment space (54) Sterile container cap, wherein at least one filter system (2; 2') is preferably fixed 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...
