Definitions
- the invention relates to a sterilization container for receiving surgical instruments or other items to be sterilized during sterilization and for maintaining sterility during storage and transport. Sterilization containers of this type must enable media exchange within the sterilizer during sterilization.
- sterilization containers To enable media exchange, it is known to equip the sterilization containers with double valves, which open and close alternately within the sterilizer during the sterilization process, depending on the pressure difference that occurs, and remain closed after the sterilization process in order to prevent the sterile goods from penetrating during storage protect from microorganisms.
- Such sterilization containers are known for example from DE-AS 12 17 550, 12 17 551 and DE-PS 16 42 161 and 32 02 430.
- Other known sterilization containers have container openings which are equipped with a filter through which the media exchange takes place in the sterilizer during the sterilization process and which are intended to form a barrier against the penetration of microorganisms during the storage of the sterilization container after completion of the sterilization process.
- Sterilization containers of this type are known, for example, from DE 34 38 463 C2. From this patent it is also known to mount a filter sheet and a filter holding plate that is under spring tension in such a way that when a predetermined pressure difference is exceeded, the filter sheet can be lifted off from the cover openings with the release of a secondary flow path. A bypass is released as soon as the external pressure becomes so high that there is a risk of the container being crushed.
- a pressure relief valve also provides DE 41 25 673 Cl. This pressure relief valve, which opens when a predetermined external pressure occurs inside the container, can be inserted into a guide on the container wall. A filter, which is assigned to a further container opening, can be inserted into a similar guide.
- valve-filter combinations are provided solely as a protective function to prevent the container from being squeezed together.
- the media in the sterilizer was intended to be exchanged through these filters.
- the filters were accordingly designed in such a way that they could compensate for the pressure differences that occurred sufficiently quickly. This necessitated a corresponding pore size, which was small enough to protect the contents of the container from dust and large-volume germs, but could not ensure that no microorganisms - especially extremely small viruses or fungal spores - penetrate. In the sterilization containers equipped with filters, there was therefore an increasing risk of penetration of microorganisms over time.
- the object of the invention is therefore to create a sterilization container equipped with a filter, in which the filter is fine-pored and is designed in such a way that the ingress of microorganisms after sterilization is not to be feared even after prolonged storage Autoclaves occurring, temporarily effective pressure differences can be reduced without damage to filters or containers.
- inlet and outlet valves are thus provided in addition to the filter, which are also intended to be effective during the sterilization process and not only as a safety serve valves, and which become effective as soon as the pressure difference from outside to inside or from inside to outside has become so great that the media exchange through the filter material itself cannot take place quickly enough.
- the invention is based on the knowledge that sterilization containers can be equipped with filters of any desired size if care is taken to ensure that a bypass in both directions, i.e. is created not only from the outside in, but also from the inside out when a pressure difference predetermined by the construction is exceeded.
- filters and valves are arranged in a common container opening, for example in an opening of an intermediate cover provided with a protective cover, or in a container wall or in the bottom.
- filters and at least one of the valves in different container openings, which can be useful, for example, if a condensate drain valve is to be arranged on the bottom of the sterilization container.
- This condensate drain valve can then be designed at the same time as a pressure relief valve, via which an increased internal pressure in the container can be reduced.
- the two valves can be integrated in the holding frame of the filter in such a way that there are no externally movable parts that could collide with the contents of the container or that can be manipulated from the outside.
- the filter material can have almost any flow resistance and nothing can slip, thereby eliminating the risk of an open bypass remaining after completion of the sterilization process
- the filter always seals correctly in the arrangement according to the invention.
- the entire arrangement (bypass with filter) is immovably installed, which gives a two-fold safety advantage:
- all known filter materials can be used, for example sheet filters made of paper, plastic or textile fabric, but also membrane filters or 3D volume filters and suspended matter filters, through which even viruses or fungal spores can be prevented.

- FIG. 19 is a view of the filter / valve combination according to FIG. 17 viewed from below;
- FIG. 20 is a section along the line XX-XX in FIG. 18.
- the sterilization container shown in Fig. 1 corresponds in its basic structure to the sterilization container according to DE 31 46 349 AI, and it consists of a lower container part 10, an intermediate cover 12 which is placed over a sealing ring 14 on the inwardly drawn edge of the lower container part and one closed container lid 16, which overlaps the lower part of the container with an intermediate lid and leaves a layout gap 18 for media exchange during the sterilization process in the sterilizer.
- the intermediate cover carries a filter-valve combination 20 for the purpose of media exchange, which can be seen in detail in FIGS. 2 to 5. This filter-valve combination 20 in the double lid proves to be useful because it is protected by the overlapping container lid 16.
- valve rings 22, 24 are clamped, which clamp the edge 26 of the opening of the intermediate cover 12 between them.
- the two valve rings 22, 24 are of identical design, but are rotated by 180 ° in their installed position and placed on top of one another in reverse (FIG. 5).
- the valve rings could also be made in one piece.
- the valve rings 22, 24 carry a filter holding plate 28, which is provided in the central region with perforation holes 29 for media exchange and that on the one hand
- valve ring 22 has an arc slot 30 on the side above the valve ring 22 and holes 32 on the other side above a semicircle.

In the area of the other arch Shaped chamber 56, the valve ring 22 has a lip seal 60 standing from the outside inwards, which is biased against the horizontal leg of the ring frame 34 and seals the holes 38.
- the filter disk 50 is fixed immovably with respect to the intermediate cover 12 via the holding frame, which is formed by the ring frame 34, the valve ring 22 and the filter holding plate, with tensioning via the tensioning disk 46. If, during the sterilization process, the differential pressure between the outside and the inside exceeds a value which can no longer be compensated for by the filter 50, then the lip seal 58 is lifted off the filter holding plate 28, so that media exchange via the holes 32, the partial chamber 54 and the arch slot 40 can be done. In contrast, if the pressure difference between the interior of the sterilization container and the sterilizer exceeds a predetermined value during the sterilization process, then the lip seal 60 is lifted off from the holes 38 and a bypass is released via the chamber section 56 and the arch slot 30.
- the filter holding plate remains immovably clamped, so that no faults can occur if parts of the container contents come close to the filter.
- these can be bridged for protection. This can be done, for example, by forming bridge webs over the holes or slots when punching out the holes or slots.
- Intermediate cover 12A is formed as an upper filter holding plate and for this purpose has a perforation 29A, under which the filter disc 50A is clamped.
- this can be any filter, namely, as outlined on the right, a thin flat filter, and, as can be seen from the left half, a thicker filter, for example a ceramic filter or volume filter.
