Definitions
- the present disclosure relates to a sterilization container with at least one opening in its housing and at least one valve unit, a sterilization system, and a method for opening and closing the opening by means of a valve unit.
- Medical sterilization containers are used to sterilize, transport and store surgical cutlery or material.
- An opening is required so that hot steam can get into the medical sterilization container during the sterilization process in a sterilizer, preferably in an autoclave.
- the opening is equipped with a sterilization filter before the sterilization process.
- the sterilization filter allows fluid exchange, but does not allow unwanted pathogens to enter the medical sterilization container.
- the opening of the medical sterilization container is closed by a filter unit which has many small fluid exchange openings / pores, which allows an exchange of fluids or their molecules, but the penetration of germs, bacteria or the like, which are larger than the molecules the fluids are prevented after the sterilization process.
- the sterile filters for sterile filtration for medical sterilization containers are usually designed in the form of a flat circular filter disk.
- the filter disc has fluid exchange openings (also called pores) for the exchange of fluids, in particular gases, liquids or gas-liquid Mixing allowed between the environment and the interior of a medical sterilization container.
- the medical sterilization filter is held in a filter holder that is attached to the medical sterilization container. The filter holder clamps the sterilization filter between a first and a second holding surface.
- sterile filtration the microorganisms are separated from a fluid by filtration.
- Membranes with a pore diameter of 0.22 miti are mostly used as filters. However, it can also make sense to use smaller pore diameters, approximately 0.1 mm. This means that only small molecules can pass through the membrane, larger particles such as bacteria are retained.
- Sterile filtration is often used to sterilize heat-sensitive solutions, such as tissue culture solutions containing serum.
- Other main applications of sterile filtration include the filtration of aqueous solutions, heat-sensitive nutrient solutions, vitamin solutions, serums, virus vaccines, plasma fractions and protein solutions.
- the sterilizer therefore uses valves (hydraulically / pneumatically controlled) or mechanisms similar to valves to quickly compensate for excess and negative pressures in the interior of the container. These create a larger opening gap for quick ventilation of the interior of the sterile container.
- sterile containers use a so-called flexible filter holder for this purpose, which bends elastically when the container is suppressed and creates a gap-like bypass. If there is overpressure in the container, the entire lid lifts off via a springy closure.
- special valve systems are used in the prior art, including double-acting valve systems, thermally activated valve systems and absolute pressure-activated valve systems. The latter are used in particular to discharge condensate, but also work by creating a bypass through which the condensate drains.
- the object of the invention is therefore to provide an active system for opening and closing media compensation openings in sterile containers and to eliminate the disadvantages mentioned above.
- the task is to reduce or eliminate the opening and closing tolerances of the media exchange system.
- incorrect openings in the media exchange system should be avoided (eg in the case of damaged systems).
- the valve position should be monitored before and after the sterilization process and thus an automated check of the functionality of the system.
- Another task is to optimize the sterilization process and simplify media exchange.

- the sterilization container according to the invention has an opening / media exchange opening / ventilation opening.
- This opening can be opened and / or closed by the valve unit.
- the valve unit is of an electro-mechanical type, which means that the valve unit has elements that are electrically driven, for example an electro-mechanical actuator. Since the valve unit is of an electro-mechanical type, the sterilization container has at least one energy source, such as batteries, accumulators, capacitors or the like. Furthermore, the sterilization container has a control unit / control device / control unit which controls the electromechanical valve unit, as a result of which the actuator moves a valve body in order to open and / or close the opening.
- the valve unit is a component for shutting off or controlling / regulating the flow of fluids.
- the valve unit has the valve body / closure part / shut-off device (eg plate, cone, ball or needle), which is preferably moved approximately parallel to the direction of flow of the fluid.
- the current will interrupted by pressing the closure part with a sealing surface against a suitably shaped opening, ie the valve or sealing seat.
- An electro-mechanical valve unit is understood to be a valve unit in which mechanical processes / valve processes are generated with the aid of electrical drives.
- Actuators or actuators convert electrical signals (e.g. commands issued by the control unit / control computer) into mechanical movement or other physical variables and thus actively intervene in the opening / closing process.
- the electro-mechanical actuator can be an electric motor, a linear motor, a piezomotor or the like.
- Other types of actuators can also be used, such as a hydraulic actuator, a pneumatic actuator or a magnetosensitive actuator.
- the displacement or force transmission of the actuator can be carried out by known mechanical principles, such as, for example, by a gear transmission, by the stroke of a thread / fine thread, by a lever mechanism , by a magnetic mechanism or the like.
- a linear stroke is preferably carried out.
- valve body is a sterilization filter unit or that the valve body is a lid of the sterilization container.
- the valve body can be used for any opening of the sterile container.
- the actuator can move part of the valve unit or the valve unit as a whole and thus open or close an opening.
- the actuator can lift / move / tilt a lid or the like of the sterile container and thus enable fluid exchange between the interior of the container and the exterior of the container.
- the actuator can also move a part of the sterile filter unit, such as a sterile filter, in a holder provided for this purpose and thereby open or close an opening.
- it can also be a specially designed and adapted for media exchange opening by means of Valve unit and thus by means of the actuator which moves a valve body can be opened or closed.
- a combination of the aforementioned options can be implemented.
- the sterile container preferably has at least one sensor unit that is provided and adapted to communicate with the control unit.

- the pressure sensor preferably measures a pressure difference between the housing internal pressure and the ambient pressure.
- the sensor thus detects at least one pressure difference between the interior of the sterile container and the sterilizer chamber.
- the valve system / valve unit is controlled based on a defined limit value and the media exchange opening is released / opened.
- the above can also be used analogously for other types of sensors.
- the temperature sensor preferably measures an outside temperature and / or an inside temperature of the sterile container.
- the moisture sensor preferably measures an outside humidity and / or inside humidity of the sterile container.
- the sensor unit can also consist of a combination of different sensors, in particular according to the above list.
- the actuator is controlled, preferably actively, on the basis of the sensor data.
- the sensor unit can be attached in the sterile container, outside on the sterile container or outside and inside.
- An embodiment is also possible where the sensor is mounted in the sterilizer or its chamber and sends the sensor signals to a receiving unit in or on the sterilization container.
- Sensor modules are also conceivable, which can be added to a screen basket, a container, a soft packaging or a wrap-packed sterile goods.
- the valve unit preferably has at least one transmitter and / or receiver, each of which is provided and adapted to communicate with the control unit.
- the sterilization container preferably has a receiver that receives signals from a transmitter in the sterilizer or its chamber and actuates the actuator at the start of the sterilization and thus opens the opening or closes the opening at the end of the sterilization.
- the sterile container preferably has the receiver, whereby the opening can be opened upon receipt of a signal that signals the start of a process and the opening can be closed upon a signal that the end of a steeping process reports.
- the received signal can also be received by the transmitter of a transmission unit (analogous to the transmission unit disclosed above) in the sterilizer.
- the sterile container has a transmitter so that the sterilization only takes place when the sterile container has been in the sterile container for a predetermined time (for example 10 seconds).
- the transmitter and / or the receiver can preferably also be an RFID chip, which also stores data about content, sterilization processes, etc. and is thus tracked in order to follow the process flow of the sterilization container live / online.
- the actuator is controlled as a function of the sterilization process and / or the prevailing environmental conditions.
- a process-controlled media exchange system is controlled by active communication between the sterilizer and actuator control.
- the actuator is actuated in accordance with the currently running process step and regardless of the differential pressure, temperature and / or absolute pressure, and the valve is thus opened or closed.
- the opening is opened by the actuator at the beginning of the sterilization, or as soon as the sterile container is in the sterile area, and closed by the actuator before or at the end of the sterilization process, that is to say before the sterile container leaves the sterile area.
