Description

[0001] SYSTEM AND APPARATUS FOR TESTING THE HERMETIC

[0002] SEALING OF CONTAINERS FOR THE STERILIZATION OF

[0003] INSTRUMENTS AND RELATED CONTAINER

[0004] The present invention refers to a system for checking the hermetic seal of containers used for the sterili zation of instruments .

[0005] The present invention also refers to an apparatus of a system for checking the hermetic seal of containers used for the sterili zation of instruments .

[0006] The invention also refers to a modi fied container for checking the hermetic seal of containers used for the sterili zation of instruments .

[0007] In general , the present invention refers to : containers specially designed for packaging, protecting, dispensing, collecting or disposing of surgical or diagnostic instruments ; devices to veri fy the ef fectiveness or maintenance of sterili zation inside the container .

[0008] In particular, the present invention refers to : seals , for example doors , covers , valves , locks ; sterili zation chambers ; means of aseptic storage .

[0009] The state of the art is represented by utility model DE 2020- 12010704 U1 concerning a container for sterile surgical instruments composed of at least two housing parts that j oin together hermetically . The container is equipped with a vapor-permeable passage element and at least one internal air control valve , as well as at least one indicator .

[0010] At least one internal air control valve and at least one indicator may be located on a wall of a part of the housing or on the passage element .

[0011] A vapor-permeable passage element can be closed by a sealing lid .

[0012] Furthermore , the state of the art is represented by utility model DE 2020- 11051767 U1 concerning a medical sterile container with a pressure-activated sterili zation status detection device , comprising hermetically closing upper and lower parts . There is no mention of leak tests or speci fic checks on the tightness of the container .

[0013] The state of the art mentioned above may present the following critical issues during the use of containers . It is important to pay particular attention during the use , handling and maintenance of containers to ensure their integrity and hermetic seal , thus preserving the sterility of their contents and the safety of patients during surgical procedures .

[0014] Frequent Use of Containers : containers are often used to hold sets of surgical instruments needed for frequent procedures . This means that a single container could be sterili zed and used multiple times throughout the day .

[0015] Container overloading : one of the common problems is overloading of containers with weights that exceed the recommended load handling limit , often over 10kg . Due to this excess weight , containers can fall to the ground, usually right on the edges , causing damage .

[0016] Need for thermo-disinfection; after each use , containers should be heat-disinfected or saniti zed before being reused . During this process , containers are separated and, i f possible , filters are removed . They are then loaded onto instrument washer trolleys , usually upside down to avoid water accumulation, which can cause damage .

[0017] Marks and damage during thermal disinfection : during the thermal disinfection step, the bottom o f the container can be placed on the trolleys in a rough way, causing marks and damage . These marks can af fect the airtight seal between the bottom and the lid .

[0018] Damage during manual washing : when washing manually, especially with large containers , it is easy for the edges of the containers to hit the edges of the sinks , causing damage and marks to the edge of the container .

[0019] Damage during handling : during loading and unloading from autoclave baskets or handling trolleys , containers can suf fer impacts , particularly on the handles and label holders . These components , being screwed or riveted, could loosen the correct coupling tension, putting the hermetic seal at risk .

[0020] Possibility of pinching the gasket : sometimes , when closing the lid, the sealing gasket may be pinched i f the lid is not positioned correctly and hastily . This can cause damage or cuts to the gasket , compromising the hermetic seal , especially in the corners .

[0021] Risk for internal sterility : all these critical issues can damage the containers and put their hermetic seal at risk . This could result in the loss of sterility within the container, resulting in patient safety risks during surgical procedures .

[0022] The obj ect of the present invention is solving the aforementioned prior art problems by providing an innovative system for veri fying the correct hermetic seal of the containers used in the sterili zation of surgical instruments , by effectively addressing the critical issues that emerge from the use of the containers .

[0023] The characteristics of a system of this type are listed below .

[0024] Reproducible veri fication of the seal : the proposed solution allows a reproducible veri fication of the hermetic seal of the containers Using a speci fic vacuum system and a vacuum gauge , it is possible to evaluate whether there are vacuum leaks inside the container, identi fying any sealing problems .

[0025] Direct testing of the original container : the solution allows directly testing the original container, without the need to individually check the constituent parts (bottom and lid) , allowing to simpli fy the control process and save time . Versatile test methods : the test can be carried out either by creating a negative pressure inside the container or by applying positive pressure . This flexibility allows locating leaks under di f ferent conditions .

[0026] Finding the exact location of leaks : in case a leak is found during the test , it is possible to precisely identi fy the exact location where the leak occurs . Using a soapy solution and positive pressure , the bubbles reveal the leak point , allowing for an accurate diagnosis .

[0027] Furthermore , a possible test for leaks using negative pressure inside the container can be considered . This test involves the creation of a negative pressure inside the container, while on the outside of the container, near the critical points such as the bottom / lid coupling point and the various rivets , a " torch" is used from which smoke escapes , generally white smoke generated by heating glycerol which is non-toxic . In the event that a leak occurs , the smoke is drawn back by the negative pressure generated inside the container . This method is already success fully used to detect leaks and is an additional option for accurately identi fying leak points . Use of certi fied and validated instrumentation : the solution uses certi fied and validated instrumentation to guarantee reliable and precise results during the leak test .

[0028] Reproducibility and regulatory compliance : the proposed test method is highly reproducible and helps ensure the regulatory compliance necessary to demonstrate the tightness of couplings . This is essential for container manufacturers .

[0029] Overcoming the limitations of the previous standard : this solution overcomes the limitations of the technical standard UNI EN 868- 1 : 1999 , which required a test with a vacuum bell , but which today is no longer applicable due to the embossing present on the container lids in aluminium .

[0030] The obj ect of the present invention is therefore solving the aforementioned prior art problems by providing a system for carrying out the veri fication of the hermetic seal of containers used for the sterili zation of instruments which represents , in particular, a signi ficant advancement in the veri fication of the hermetic seal of the containers used in the sterili zation of surgical instruments .

[0031] Another obj ect of the present invention is providing a system that allows for the implementation of a reliable , reproducible and regulatory compliant method for identi fying and solving leakage problems during use , thus helping to ensure patient safety during surgical procedures Furthermore , an obj ect of the present invention is providing an apparatus that allows the hermetic seal of containers used for the sterili zation of instruments to be veri fied by appropriately connecting a vacuum or pressure generation device with a detection device to monitor variations in pressure , and a control means for managing the process of generating vacuum or pressure .

[0032] Furthermore , an obj ect of the present invention is providing a modi fied container that allows speci fic leak tests to be carried out during the use of containers used for the sterili zation of instruments and to facilitate leak tests during sterili zation .

[0033] The above and other obj ects and advantages of the invention, as will appear from the following description, are achieved with a system for veri fying the hermetic seal of containers for the sterili zation of instruments as claimed in claim 1 . Furthermore , the above and other obj ects and advantages of the invention are achieved with an apparatus and a container as described in the respective independent claims .

[0076] - a gasket to hermetically close the holes for balancing the pressure of the container.

[0077] The Container Control System (CCS) is a system designed to guarantee the correct sealing of containers used in the sterilization of surgical instruments using saturated steam. The system allows optimizing the sterilization process and guaranteeing the sterility of the material inside the containers during cooling, storage and transport .

[0078] CCS represents a fundamental system to guarantee the safety and effectiveness of the sterilization process of surgical instruments, minimizing the risk of contamination during the post-sterilization steps, such as cooling, storage and transport.

[0079] The main components and functionalities of the CCS are described below: saturated steam sterilization process: the CCS is designed to be used in conjunction with the saturated steam sterilization process. The process takes place inside an autoclave or a sterilization chamber and involves several steps, including the removal of air, the introduction of steam, the achievement of sterili zation parameters , the actual sterili zation step, the drying and baric balancing; sterili zation containers : the CCS is speci fically intended to allow monitoring and guaranteeing the hermetic seal of the containers used for the sterili zation of surgical instruments . Containers of this type consist of two parts : the bottom, where the instruments are placed, and the lid, which must be hermetically closed to ensure sterility .

[0080] Types of containers

[0081] Sterili zation containers may vary in their construction . Below are some common types : a . Container with Bio-Barrier Filter : these containers are equipped with disposable or multiuse filters (made of paper or PTFE ) to allow the suction of air, the introduction of steam during the sterili zation step and to filter the air during storage to keep the internal / external pressure level . The filters are generally positioned on the lid, but in some cases they can also be present on the long side of the base . b . Bio-Barrier Valve Containers : these containers use an automatic two-way valve in place of filters to allow air and vapor to pass through . The design of the valves prevents the entry of microorganisms after sterili zation . The bio-barrier is usually riveted to the lid and is not removable . c . Containers with Pasteur System Bio-Barrier : this type of container uses a tortuous concentric path known as the Pasteur system as a bio-barrier system . This system is generally removable to facilitate cleaning . Purpose of the Bio-Barrier : The bio-barrier present in sterili zation containers is intended to ensure that the material inside the container remains sterile after the sterili zation process . During cooling, storage and transportation, the volume of air inside the container can vary, and the bio-barrier prevents the accidental entry of contaminating particles or microorganisms . d . Carry-over containers : in addition to standard sterili zation containers , there are also carry-over containers . These containers are completely airtight , with non-perf orated bottom and lid, and are used for handling dirty instruments safely .

[0082] Bottom-lid coupling in containers and "Critical Points" : the hermetic coupling between the bottom and the lid of containers is a critical aspect for the sterili zation of surgical instruments . The presence of gaskets , handles and nameplate holders , as well as the fixing of the valves , helps to ensure that the sterili zation process occurs safely and that the sterility of the contents is preserved during all subsequent steps , including cooling, storage and transportation .

[0083] Perfect seal between bottom and lid : in all containers used for sterili zation, it is essential to guarantee a perfect seal between the bottom and the lid . This means that only the bio-barrier system needs to allow air to pass through to manage pressure variations . The hermetic seal between these two parts is essential for maintaining the sterility of the contents .

[0084] Sealing gasket : a gasket is mounted around the entire perimeter of the container lid to ensure an airtight seal between the lid and the bottom . This seal plays a crucial role in ensuring hermetic insulation between the two components of the container .

[0085] Critical coupling point : the coupling between the bottom and the lid represents the main critical point of the containers . I f the assembly is not perfect and the hermetic seal is not guaranteed, during the steps in which the container draws air from the outside to rebalance the pressure , air could infiltrate more easily from a defective point of the coupling rather than passing through , through the bio-barrier system . The passage of external air inside the container from a point without a filtering system could compromise the sterility of the contents .

[0086] Handles for handling : each container is equipped with handles provided to facilitate handling . These handles are installed on the body of the container and allow it to be moved safely . Generally, they are fixed using screws passing through the inside of the bottom of the container or with rivets .

[0087] Tag holders for traceability : on the outside of the containers there are tag holders where identi fication tags or labels are placed for traceability purposes . These label holders are also usually fixed with screws passing inside the bottom of the container or with rivets .

[0088] Fixing the valves in containers with a valved bio-barrier : in containers with a valved biobarrier, the valves are securely fixed to the l id using through rivets . This ensures that the valve remains integrated into the container without the possibility of dismantling, thus contributing to the ef fectiveness of the bio-barrier system .

[0089] Container lid section : the container lid section has a central hole located near the Pasteur type filter system . This hole allows the insertion of a dedicated connector to test the container ' s tightness . By unscrewing the screw in the central hole , the connector can be screwed on, allowing the seal to be checked . A ring made of silicone or silicone material is provided to ensure a hermetic seal of the holes through which air passes into the Pasteur system .

[0090] Additional version with modi fied carryover container : an additional version of the carryover container has been developed, which includes fittings for air intake and blowing . With this version of the carry-over container, it is possible to use the lid to test the tightness of the bottom of standard containers . Furthermore , using the bottom of the modi fied carryover container, it is possible to test the lid of standard containers . For this version, a dedicated pump for air intake and insuf flation is available , together with a precision digital vacuum gauge , which has been validated and certified for testing purposes.

[0091] Modified landfill container with air fittings: the modified landfill container has been further adapted with the addition of air intake and insufflation fittings. These fittings are located on both the lid and the bottom of the hauling container. This configuration allows for greater flexibility in performing leak testing on various components of standard containers.

[0092] Version with direct modification of the sterilization container: a further option involves direct modification of the standard sterilization container. This modification includes the addition of a central hole near any filter system. By unscrewing the screw in the hole, it is possible to apply the dedicated connector after inserting a gasket to hermetically seal the openings of the filtration system. This configuration allows direct leak testing of the sterilization container without the need for an additional carryover container.

[0093] Below are additional notes that provide an overview of the various considerations and features of the CCS system:

[0094] Use of the UNI EN 868-1:2009 standard: the aforementioned UNI EN 868-1:2009 standard is intended only for the manufacturer.

[0095] Adaptability to different bio-barrier systems: the project was studied using a container with biobarrier with a Pasteur system. It is logical that with the appropriate modifications it can be applied to any container with bio-barrier systems other than the Pasteur system.

[0096] Unique identification of components: it is possible to apply a Data Matrix, a QR Code or other system that makes the components of the container unique, allowing the monitoring and linking of leak test data to each component. The data can be stored and viewed using dedicated software.

[0097] App to document leak tests: an app is being developed that will document leak tests carried out on containers, associating the results, graphs and notes with specific components. The technician will be able to indicate whether the test was passed or not and add notes.

[0098] Customer database to store results: a database will be created to enter container leak test results for different customers (hospitals) over time, providing a history of tests performed.

[0099] Customizable advanced sealing systems: advanced sealing systems can be provided for dif ferent types of containers , with the aim of hermetically closing the accesses to the filter system during leak tests .

[0100] Lack of existing solutions : currently there is no container equipped with a system to carry out correct , repeatable and reproducible leak tests , nor is there a dedicated system to test the container for leaks .

[0101] Use of existing devices for aspiration and insuf flation : initially, it is suggested to use existing devices for aspiration and insuf flation, such as pumps and certi fied digital vacuum gauges . In the future , an ad hoc device with a vacuum regulation valve could be developed .

[0102] Increased safety in the use of containers : the proposed changes can provide greater safety in the use of containers by enabling leak testing of the bottom-to-lid fit and promoting the use of safe containers .

[0103] Compliance with the UNI EN ISO 11607- 1 standard : the proposed changes to guarantee terminal sterili zation and maintenance of sterility are in line with the UNI EN ISO 11607- 1 standard, which establishes the minimum requirements for the use of packaging systems that provide appropriate sterile barrier systems.
