Description

Technical Field

[0001] The present invention relates to the reprocessing of reusable medical instruments, such as dental instruments. Background Art

[0002] Reusable medical devices are devices that can be reused by a healthcare provider to diagnose and / or treat multiple patients. Examples of reusable medical devices include medical devices used in dental care, such as scalpels, syringes, specula, scopes, drills, burs, disks, handpieces, excavators, turbines, files, reamers, and the like.

[0003] While used on patients, reusable instruments become dirty and contaminated with blood, tissue, and other biological debris, such as microorganisms. To avoid any risk of infection from contaminated instruments, reusable instruments undergo reprocessing, a process known as decontamination, such as cleaning and disinfection and / or sterilization. Reprocessing allows medical devices to be safely used more than once on the same patient, or more than once on more than one patient. Proper reprocessing of reusable medical instruments is crucial to protecting patient safety. Summary of the Invention

[0004] It is an object of the present invention to provide a system and method that makes the task of decontaminating medical instruments less cumbersome, less time consuming and / or less expensive. More generally, it is an object of the present invention to provide a method and system for reprocessing reusable medical instruments.

[0005] In addition, according to one aspect, a method for reprocessing reusable medical devices is provided. The method includes providing a container comprising a tray and a lid. The tray includes one or more supports for supporting the medical devices. The tray includes an opening for inserting the medical devices through the opening into an interior space of the tray. The lid is configured to close the opening. The method includes inserting the container into a decontamination apparatus. The method includes decontaminating the tray, lid, and medical devices within the decontamination apparatus, with the lid positioned away from the opening. The method includes closing the container within the decontamination apparatus by a container handling device of the decontamination apparatus by closing the lid onto the tray to close the opening. The method may include sealing the container within the decontamination apparatus, such as within a clean area of ​​the decontamination apparatus, such as a cleanroom. The method includes removing the closed container containing the decontaminated medical devices from the decontamination apparatus. Once the tray, lid, and medical devices have been decontaminated, the container is closed and optionally hermetically sealed. The container is sealed within the decontamination apparatus, such as within a clean area of ​​the decontamination apparatus, such as a cleanroom. Thus, the decontaminated container can be enclosed around the decontaminated medical devices within the clean area of ​​the apparatus. This facilitates decontamination of the contents of the container, i.e., the medical devices. Additionally, during the decontamination process, the cover is positioned away from the opening, allowing for easy access to the interior space and the medical device during the decontamination process.

[0006] The container is preferably such that when positioned in a normal use position (e.g., placed on a table), the opening extends substantially horizontally. Preferably, when the container is in the normal use position, the medical device is positioned in a lying position within the container. Preferably, when the container is in the normal use position, the medical device is positioned (substantially) horizontally within the container.

[0007] Optionally, the method includes maintaining the tray in a position in which the openings extend in a vertical plane while the purification is being performed. Thus, the plane in which the openings extend is upright, e.g., substantially vertical, e.g., vertical. This allows for easy access during the purification process. This also facilitates dripping of liquids used during the purification process. The one or more covers may also be maintained extending in such a vertical plane. The one or more covers may be moved, for example, away from the one or more openings, e.g., along an axis extending perpendicular to the one or more planes in which the one or more openings extend. Thus, the one or more covers may be maintained close to the tray while still allowing good access to the interior of the tray for purification.

[0008] Optionally, the medical device or devices to be cleaned are held in an upright position during the cleaning process. For substantially elongated medical devices, in the upright position, the elongated main axis of the device is upright, such as substantially vertical. When the container is in its normal position of use, when the medical device is positioned (substantially) horizontally in the container, the medical tools can also be held in a vertical position when the tray is held in a position in which the opening extends in a vertical plane. Liquids can then drip easily from the medical device. In addition, the contact area between the device and the support can be minimized. In particular, when jets are used during cleaning and / or when ultrasonic cleaning is used, the contact point will change during cleaning, thereby allowing complete cleaning of the device.

[0009] Alternatively, the container can be inserted into the purification device in an unsealed state. Thus, unsealed containers can enter the purification device, and sealed containers can exit the purification device. Processing containers inserted into the purification device in a sealed state may require additional and / or more complex handling of the container. If the container is inserted into the purification device unsealed, the operation of the purification device can be independent of the degree to which the user seals the container before inserting it into the device. Therefore, a simpler purification device may be sufficient for processing containers inserted into the purification device in an unsealed state.

[0010] In the unsealed state, the container is open to the outside air. Thus, in the unsealed state, microorganisms and other pollutants can enter the container. In the sealed state, a microbial barrier is formed that prevents microorganisms from entering the interior space. Thus, when released from the purification device, the sealed container provides protection against microbial contamination. Alternatively, in the sealed state, the container is hermetically sealed.

[0011] Optionally, the container is subsequently maintained in the first and second chambers during the decontamination step. Optionally, the method comprises washing in the first chamber of the decontamination apparatus and sterilizing in the second chamber of the decontamination apparatus.

[0012] Optionally, cleaning comprises one or more of rinsing, washing, disinfecting, sterilizing, and drying. Optionally, cleaning comprises ultrasonic cleaning. Washing may comprise washing at a low temperature, such as at about 37°C, to avoid blood clotting. Alternatively or additionally, washing may comprise washing at a high temperature, such as at 50-100°C, such as at about 73°C. The cleaning steps may be performed in two chambers or in more chambers. For example, each cleaning step may be performed in a dedicated chamber.

[0013] Optionally, the first chamber and the second chamber are positioned so that their respective main extension planes are substantially parallel. Here, the main extension plane represents the direction of the two maximum dimensions of the chamber. For example, for a chamber having a length that exceeds the width and a width that exceeds the height, the maximum dimensions are the length and the width. Thus, the main extension plane is the plane defined by the length and the width of the chamber. When the first chamber and the second chamber are positioned so that their respective main extension planes are substantially parallel, the first chamber and the second chamber occupy a compact volume. Thus, a compact configuration of the purification device is possible. When the purification device includes more than two chambers, preferably, the more than two chambers are positioned so that their respective main extension planes are substantially parallel.

[0014] Optionally, the container is closed while being moved from the first chamber to the second chamber. Thus, the container is opened in the first chamber for processing, moved from the first chamber to the second chamber in a closed state, and reopened in the second chamber for further processing. This offers the advantage that the interior of the container is not contaminated from outside the first or second chamber. This also offers the advantage that the purification device is not contaminated while the container is outside the first or second chamber. When the purification device comprises two or more chambers, the container is preferably closed while being moved from one chamber to the next.

[0015] Alternatively, the closing step comprises closing the container airtightly. Alternatively, the method further comprises reducing the air pressure in the container before closing the container, and maintaining the reduced air pressure in the container after removing the closed container from the purification device. Thus, the purified medical device can be stored under reduced air pressure until the next use. The container may include an anti-tampering feature, which is arranged to be in a first state when the reduced gas pressure is present in the container interior, and in a second state when the ambient pressure is present in the container interior. Thus, it is easy to determine whether the container is still in a reduced air pressure state, in which the container is released by the purification device. The gas used to fill the container may be air, for example, filtered using a high-efficiency particulate air (HEPA) filter. The gas may also be an inert gas, such as nitrogen.

[0016] Optionally, the method includes applying a label to the container within the purification device. Optionally, the method includes labeling the container with a label representing the purification performed, for example, using a labeling unit of the purification device. The label can be, for example, a sticker or printed onto the container. Thus, the purification performed on the instrument can be determined from the label. The label can include information about the purification performed, such as a code indicating the processing steps performed. The label can also include information indicating the location in a database where information about the purification performed is stored. The label can also include information indicating the date and time of the purification.

[0017] Optionally, in the unsealed state, the perforations of the lid and / or tray provide an open connection from the interior space of the container to the ambient air. Optionally, the method includes sealing the perforations with a label. The label can hermetically seal the perforations. Thus, removal of the label can break the seal. The label can be, for example, a paper and / or plastic label. Furthermore, by the sound of the perforations of the container filling with air when the label is removed, the user can confirm the presence of the hermetic seal before opening the container.

[0018] Optionally, the container includes a further lid. The tray may have a further opening, preferably opposite the first opening, the further lid being arranged to close the further opening. The method may include, within the decontamination apparatus, decontaminating the tray, the lid, the further lid, and the medical device when the lid is positioned away from the opening and the further lid is positioned away from the further opening. The method may include, within the decontamination apparatus, the container handling device closing the lid onto the tray to close the opening and closing the further lid onto the tray to close the further opening. It will be appreciated that when decontaminating a container having both a lid and a further lid, the tray, the lid, the further lid, and the medical device may also be decontaminated when only one of the lid and the further lid is positioned away from the opening or the further opening, respectively.

[0019] Optionally, the opening spans substantially the entire cross-sectional area in a top view of the tray. The opening may for example be greater than 80%, preferably 90% of the cross-sectional area in a top view of the tray. A side wall of the tray, such as a substantially vertical side wall, may define the opening.

[0020] Optionally, in a top view of the tray, the further opening spans substantially the entire cross-sectional area. The further opening may, for example, be larger than 80%, preferably 90%, of the cross-sectional area in a top view of the tray. A side wall of the tray, for example a substantially vertical side wall, may define the further opening. The tray may be substantially tubular. A tubular tray may have a length that is less than a dimension orthogonal to the length (in the direction from the first opening to the second opening). The one or more supports of the tray may be arranged to hold one or more medical devices between the opening and the further opening. The one or more supports may be arranged to lock the one or more instruments in the tray to prevent the one or more instruments from falling out of the tray, for example regardless of the orientation of the tray.

[0021] Optionally, the inserting step includes inserting the container into the decontamination device while the lid and optional further lid are closed onto the tray. Thus, a closed container, preferably containing one or more medical devices to be decontaminated, can be inserted into the decontamination device. Thus, a user can collect the medical devices in the container after use on a patient, close the container, and place the closed container at the decontamination device for reprocessing.

[0022] Optionally, the method comprises, inside the decontamination device, removing a cover from an opening and, optionally, removing another cover from another opening. Thus, a closed container containing a medical device to be decontaminated can be inserted into the decontamination device, which opens the container to provide good access to the medical device during the decontamination process.

[0023] Optionally, the method comprises: the container handling device gripping the container by the tray, by the cover and optionally by an optional further cover. Thus, the container handling device can effectively open and / or close the container as required.

[0024] It is understood that an open container can also be provided at the purification device.For example, the tray and the lid can be provided separately to the purification device, for example in separate stacks and / or separate inlets.

[0025] Optionally, the instrument is a dental instrument. The dental instrument may be, for example, a scalpel, a syringe, a speculum, a mirror, a drill, a bur, a disk, a handpiece, an excavator, a turbine, a file, a reamer, a (plastic) reusable part, a disposable part, a prosthetic part, an implant, a 3D printed implant, an insert, a measuring device, an applicator, or the like.

[0026] Optionally, the method includes: the purification device reading a purification instruction from a machine-readable identifier of the container, and then performing the purification process according to the read instruction.

[0027] Alternatively, the decontamination device stores data representing the decontamination process for a particular container in a record in a memory. Thus, the data representing the decontamination process can be retrieved.

[0028] Optionally, the decontamination device monitors the decontamination history of a container. For example, it is possible for the decontamination device to warn that a container has not been decontaminated within a predetermined period of time, such as when the expiration date of a previous decontamination process is approaching, has been met, or has exceeded. Thus, the decontamination device can, for example, warn that the decontamination of a predetermined container is due and, for example, request that the container be brought to the decontamination device for a renewed decontamination.

The container containing one or more devices to be purified can be removed from the purification device or removed from storage and brought to the processing space. In the processing space, the purified device is removed from the container (for example, after checking for evidence of unauthorized use) and used for the process. After the process, the contaminated one or more instruments are repositioned in the container. The container is located on the purification device. For example, a reader of the purification device can determine the machine-readable identification of the holder. The corresponding record is retrieved from the memory. The processing instructions in the record can be used to perform the purification of the one or more instruments in the container. Thus, every time one or more instruments appear at the purification device, there is no need to enter the processing instructions for the same one or more instruments.

[0092] According to one aspect, a method for reprocessing reusable medical devices in a container is provided. The container includes a tray and a lid. The tray includes one or more supports for supporting one or more medical devices. The tray includes an opening for inserting the one or more medical devices through the opening into an interior space of the tray. The lid is configured to close the opening. The method includes maintaining the tray in a position where the opening extends in a vertical plane while decontaminating.

[0093] Optionally, the medical device to be decontaminated is maintained in an upright position during decontamination. For generally elongated medical devices, in the upright position, the elongated major axis of the device is upright, such as substantially vertical. Thus, the contact area between the device and the support can be minimized. In particular, when using a jet during decontamination, and / or when using ultrasonic cleaning, the contact point will change during decontamination, thereby allowing for complete decontamination of the device.

[0094] It should be understood that any one or more of the above aspects, features, and options may be combined. It should be understood that any option described with respect to one aspect is equally applicable to any other aspect. It will also be understood that all aspects, features, and options described with respect to the method are equally applicable to the system, device, and container, and vice versa.

[0104] Figure 1 A schematic diagram of an example of a reprocessing container 1 for holding reusable medical devices 2 is shown. Figure 1In the example shown, the container includes a tray 4. The tray includes a support 6 for supporting a medical device 2 or multiple medical devices 2. Here, the support 6 includes a movable support 6a that is arranged to move between an open position for inserting the device 2 and a closed position for preventing the medical device from falling out of the tray, regardless of the tray's orientation. In this example, the movable support 6a is pivotally mounted to the tray 4 at a pivot point 6b. The tray includes a first opening 8. Here, the first opening 8 extends across the entire area formed by the inner surface of the circumferential wall 10 of the tray 4. Thus, in this example, the first opening 8 spans substantially the entire cross-sectional area of ​​the tray 4 when viewed from above. Thus, the device 2 or multiple devices 2 can be easily placed into the tray's interior space 12 through the first opening 8. In this example, the tray 4 also includes a bottom 15. When used to insert and / or remove medical devices 2 from the container, the container 1 is typically positioned so that the bottom 15 rests on a supporting surface, such as a countertop or tabletop. Here, the bottom 15 is formed integrally with the circumferential wall 10 .

[0105] Here, the container 1 includes a first cover 14. The first cover is arranged to close the first opening 8. In this example, the first cover 14 includes a first circumferential seal 16. In normal use, with the bottom 15 facing downwards, opening the first cover 14 allows easy access to one or more medical devices 2 within the container 1 through the first opening 8, and the first cover 14 then extends over the upper side of the tray 4.

[0106] Figure 2 A schematic diagram of an example of a reprocessing container 1 for holding reusable medical instruments 2 is shown. Figure 3 Shown Figure 2 A perspective exploded view of a container 1 of FIG. 4 . In this example, the container comprises a tray 4. The tray comprises a support 6 for supporting a medical device 2 or a plurality of medical devices 2. Here, the support 6 comprises a movable support 6a for preventing the medical device from falling out of the tray, regardless of the orientation of the tray. In this example, the movable support 6a is pivotally mounted to the tray 4 at a pivot point 6b. The tray comprises a first opening 8. Here, the first opening 8 extends over the entire area formed by the inner surface of the circumferential wall 10 of the tray 4. Thus, in this example, the first opening 8 spans substantially the entire cross-sectional area in a top view of the tray 4. Thus, the instrument 2 or a plurality of instruments 2 can be easily placed in the interior space 12 of the tray through the first opening 8.

[0107] Here, the container 1 comprises a first cover 14. The first cover is arranged for closing the first opening 8. In this example, the first cover 14 comprises a first circumferential seal 16.

[0108] exist Figure 2In the example shown, tray 4 includes a second opening 18. Here, second opening 18 extends over the entire area formed by the inner surface of circumferential wall 10 of tray 4. Thus, in this example, second opening 18 spans substantially the entire cross-sectional area of ​​tray 4 when viewed from above. Container 1 also includes a second lid 20. Second lid 20 is used to close second opening 18. In this example, second lid 20 includes a second circumferential seal 22.

[0109] When used to insert and / or remove medical device 2 from container, container 1 will usually be placed with second cover 20 on a carrier surface, such as a countertop or table. Then, second cover 20 serves as the bottom of container 1.

[0110] In normal use, with the second cover 20 facing downwards, opening the first cover 14 allows easy access to the medical devices 2 within the container 1 through the first opening 8 , and the first cover 14 then extends over the upper side of the tray 4 .

[0111] exist Figure 1 and Figure 2 In the examples of the embodiment, the container 1 may include a machine-readable identification 34, which is a radio frequency identification RFID. In these examples, the container 1 may also include a human-readable identification 36, which is a label.

[0112] Figure 4 A schematic representation of an example of a purification device 24 is shown. The purification device 24 comprises an inlet 26. The inlet 26 is arranged for inserting a container 1 into the purification device 24. As will be described below, the purification device may be used with Figure 1 The container 1 and / or Figure 2 and Figure 3 It will be appreciated that the decontamination device 24 in combination with one or more containers 1 forms a system for reprocessing reusable medical devices 2.

[0113] The decontamination device 24 comprises a container handling device 28 arranged to hold a container 1 in the decontamination device. The decontamination device 24 comprises a decontamination unit 30 for decontaminating the container 1 and the medical device 2. The decontamination device comprises an outlet 32 ​​for removing the closed container 1 containing the decontaminated medical device 2 from the decontamination device.

[0114] In this example, the decontamination device 24 includes a reader 38 for reading the machine-readable identification 34 .

[0115] Here, the purification device 24 includes a processor 40. The processor 40 is in communication with a memory 42. The processor 40 is in communication with a user interface 44.

[0116] In this example, the purification unit 30 includes a first chamber 30A and a second chamber 30B.

[0117] The purification device 24 described so far can be referred to as follows Figure 4 and Figures 5a to 5g use.

[0118] The container 1 and the medical device 2 to be decontaminated are located at the decontamination device 24. In this example, the contaminated medical device 2 is contained in the interior space 12. Here, the container 1 is closed. The container 1 is located at the entrance 26. The reader 38 reads the identification 34 of the container. In this example, there is a stack of containers 1 at the entrance 26 (see Figure 4 ). Thus, the next container comprising the instrument 2 to be decontaminated can be placed on top of the stack and await processing by the decontamination device 24 .

[0119] In this example, processor 40 retrieves a record associated with identifier 34 of container 1 from memory 42. In this example, the record includes data representing processing instructions for decontaminating container 1. The data representing the processing instructions may be displayed on user interface 44. For example, the user interface may display a cleaning cycle retrieved from the record. It should be understood that it is possible for user interface 44 to allow manual operation of processing instructions. Alternatively, processor 40 may not retrieve processing instructions from memory 42, and user interface 44 may prompt the user to enter processing instructions for the container.

[0120] The container 1 at the bottom of the stack engages with the container handling device 28 (see Figure 5a ). In this example, the container handling device 28 includes a first jaw 48, which is arranged to engage the tray 4, here at an edge 50 of the tray 4. In this example, the container handling device 28 also includes a second jaw 52, ​​which is arranged to engage the first cover 14, here at an edge 53 of the first cover 14. The container handling device 28 may include a third jaw 54, which is arranged to engage the second cover 20, for example at an edge 56 of the second cover. It will be understood that if the purification device is arranged only for processing e.g. Figure 1 For the container shown, the third clamping jaw 54 can be omitted.

[0121] In this example, the jaws 48, 52, 54 include grooved side members 70A, 70B that are arranged to engage the front side 72A and rear side 72B of the rims 50, 53, 56, respectively. Here, the grooved side members 70B are biased by a resilient element 74, such as a spring, to close around the respective edges. By moving the grooved side members 70B against the biasing force, the distance between the grooved side members 70A, 70B can be expanded to grip the respective edges.

[0122] In this example, the container 1 is moved to the first chamber 30A while the container 1 remains in its closed state. Here, the container handling device 28 moves the container 1 horizontally from the bottom of the stack to above the second chamber 30A. The container handling device 28 then tilts the container 1 so that the openings 8, 18 (although still closed by the lids 14, 20) extend in a vertical plane (see Figure 5b ). It will be appreciated that deviations from exact verticality are possible. The container 1 is then lowered into the first chamber 30A. It will be appreciated that the generally elongated medical device 2 is in an upright position with its longitudinal axis substantially vertical.

[0123] Once in the first chamber (or upon entering the first chamber or before entering the first chamber), the first cover 14 is moved away from the first opening 8 by the second jaw 52, ​​and the second cover 20 is moved away from the second opening 18 by the third jaw 54 (see Figure 5c ). In this example, the wall 58 of the first chamber 30A includes guide grooves 60A, 60B, and 60C. When entering the first chamber 30A, the first guide groove 60A guides the first jaw 48. Here, the first guide groove 60A guides the first jaw 48 along a straight line. When entering the first chamber 30A, the second guide groove 60B guides the second jaw 52. Here, the second guide groove 60B guides the second jaw 52 along a curve. The curve of the second guide groove 60B moves the first cover 14 away from the first opening 8, thereby effectively opening the first opening 8. When entering the first chamber 30A, the third guide groove 60C guides the third jaw 54. Here, the third guide groove 60C guides the third jaw 54 along a curve. The curve of the third guide groove 60C moves the second cover 20 away from the second opening 18, thereby effectively opening the second opening 18.

[0124] Now, the container 1 is in the first chamber 30A in the open state. The inner surface of the container and the one or more instruments contained therein can be decontaminated. It should be understood that in this example, the outer surface of the container can also be decontaminated.

[0125] In this example, decontamination includes the following process steps. In this example, the first process step is rinsing. For rinsing, a jet of liquid, such as cold water, is directed into the interior of container 1. During the rinsing process, container 1 can be moved up and down relative to the jet to improve rinsing. In this example, the second process step is washing. For washing, in this example, first chamber 30A is filled with washing liquid to a level sufficient to immerse the entire container. During the washing process, ultrasonic cleaning can be used in the liquid tank in which the container and instruments are immersed. In this example, the third process step is disinfection. For disinfection, in this example, a jet of liquid, such as hot water containing a disinfectant, is directed into the interior of container 1. During the disinfection process, container 1 can be moved up and down relative to the jet. In this embodiment, the fourth process step is drying. For drying, a dry gas, such as hot air, is flowed through the open container.

[0126] It should be understood that, taking into account the above-mentioned process steps, the purification device may include one or more nozzles for generating jets, a rinsing liquid supply device, a washing liquid supply device, a disinfection liquid supply device, a liquid pump for supplying the nozzles, a liquid pump for filling the chamber, a liquid pump for emptying the chamber, a liquid heating device, a gas heating device, a blowing device and an ultrasonic transducer.

[0127] The nozzle may be placed on a structure extending from the bottom of the first chamber (see Figure 6 ). The structure can be arranged so that the tray 4 passes through the structure on one side, while the first or second cover passes through the structure on the opposite side. Thus, when the container is in its open position in the first chamber, the structure is inserted between the tray and the first or second cover. This allows for efficient positioning of the nozzle close to the tray, the cover, and the medical device. It will be appreciated that the first such structure can be inserted between the first cover and the tray, and the second such structure can be inserted between the second cover and the tray. One or more ultrasonic transducers can also be positioned on one or more of the structures.

[0128] It should be understood that the decontamination process can be modified to suit the decontamination needs of the medical devices contained in the container. For example, one or more processing steps can be omitted if desired. Process parameters such as liquid temperature, spray pressure, spray duration, ultrasound intensity, ultrasound duration, container movement during rinsing, washing, disinfection, and / or drying, gas temperature, etc. can also be varied as desired.

[0129] In this example, after drying, the container 1 is removed from the first chamber 30A. Here, during the process of lifting the container 1 out of the chamber 30A, the guide grooves 60A, 60B, 60C allow the container 1 to be closed again. Thus, a clean closed container is provided at this point. In this example, the container 1 is moved towards the label unit 62 (see Figure 5e ) Transport (see Figure 5d ) container 1. The labeling unit 62 is arranged to apply a label 64 to the container 1, here to the first cover 14. The label 64 may include a human-readable indication. The human-readable indication may, for example, include information about the decontamination process performed on the container (the contents of the container). This information may, for example, include a processing date and / or an expiration date.

[0130] In this example, the container 1 is lowered into the second chamber 30B for further processing steps (see Figure 5fOnce in the second chamber (or upon entering the second chamber, or before entering the second chamber), the first cover 14 is removed from the first opening 8 by the second jaw 52, ​​and the second cover 20 is removed from the second opening 18 by the third jaw 54. In this example, the wall 66 of the second chamber 30B includes guide slots 68A, 68B, and 68C. When entering the second chamber 30B, the first guide slot 68A guides the first jaw 48. Here, the first guide slot 68A guides the first jaw 48 along a straight line. When entering the second chamber 30B, the second guide slot 68B guides the second jaw 52. Here, the second guide slot 68B guides the second jaw 52 along a curve. The curve of the second guide slot 68B moves the first cover 14 away from the first opening 8, thereby effectively opening the first opening 8. When entering the second chamber 30B, the third guide slot 68C guides the third jaw 54. Here, the third guide slot 68C guides the third jaw 54 along a curve. The curve of the third guide slot 68C moves the second cover 20 away from the second opening 18 , effectively opening the second opening 18 .

[0131] In this example, the fifth processing step is performed in the second chamber 30B. In this embodiment, the fifth processing step is sterilization. In this example, the second chamber 30B is filled with a sterilizing gas, such as ozone, for sterilization. It should be understood that information regarding sterilization can also be included on the label 64. The label can be applied to the container before or after sterilization.

[0132] In this example, the sixth processing step is evacuation. Here, the second chamber is evacuated, for example to a predetermined pressure below the ambient pressure. In this example, during the process of lifting the container 1 in the second chamber 30B, the guide grooves 68A, 68B, 68C close the container 1 again. Here, the container is enclosed in the second chamber 30B during evacuation. Thus, the closed container contains a gas below the ambient pressure, such as air or a protective gas. The container 1 may include an indicator that is arranged to indicate whether the pressure in the container is below a predetermined threshold pressure. Thus, a sterilized closed container is provided at this point. In this example, the container 1 is transported to the outlet 32 ​​(see Figure 5g ). In this example, the container is placed at the bottom of the stack of containers at the outlet 32. The container can be retrieved from the outlet 32, for example manually.

[0133] Figure 7 A schematic representation of an example of a purification device 24 is shown. The purification device 24 comprises an inlet 26. The inlet 26 is arranged for inserting a container 1 into the purification device 24. As will be described below, the purification device may be used with Figure 1 The container 1 and / or Figure 2 and Figure 3 It will be appreciated that the decontamination device 24 in combination with one or more containers 1 forms a system for reprocessing reusable medical devices 2.

[0134] The decontamination device 24 comprises a container handling device 28 arranged to hold a container 1 in the decontamination device. The decontamination device 24 comprises a decontamination unit 30 arranged to decontaminate the container 1 and the medical device 2. The decontamination device comprises an outlet 32 ​​for removing the closed container 1 containing the decontaminated medical device 2 from the decontamination device.

[0135] The decontamination device 24 may include a reader 38 for reading the machine-readable identification 34. The decontamination device 24 may include a processor 40. The processor 40 may be communicatively coupled to a memory 42. The processor 40 may be communicatively coupled to a user interface 44.

[0136] In this example, the decontamination unit 30 includes a first chamber 30A, a second chamber 30B, a third chamber 30C, a fourth chamber 30D, and a fifth chamber 30E. In this example, the first chamber 30A is configured for washing medical instruments 2 at a low temperature, for example, 37°C, using a liquid such as water containing detergent. The first chamber 30A may include an ultrasonic device 70 for ultrasonically cleaning the instruments 2. In this example, the second chamber 30B is configured for washing medical instruments 2 at a high temperature, for example, 73°C, using a liquid such as water containing detergent. In this example, the third chamber 30C is configured for sterilizing the instruments at a temperature of, for example, 93°C. In this example, the fourth chamber 30D is configured for drying the instruments 2 and the container 1. Here, the fourth chamber 30D is equipped with a drying device, such as a blower 72 and / or a heater 74. In this example, the fifth chamber 30E is configured for sterilizing the instruments 2.

[0137] In this example, chambers 30A, 30B, 30C, 30D, and 30E are positioned so that their respective main planes of extension are substantially parallel. Here, the main plane of extension represents the direction of the two maximum dimensions of the chamber. For example, for a chamber having a length that exceeds the width and a width that exceeds the height, the maximum dimensions are the length and width. Thus, the main plane of extension is the plane defined by the length and width of the chamber. Here, the first to fifth chambers 30A, 30B, 30C, 30D, and 30E are positioned so that their respective main planes of extension are substantially parallel, so that they occupy a compact volume. Thus, a compact configuration of the purification device is possible.

[0138] The purification device 24 described so far can be referred to as follows Figure 7 use.

[0139] A container 1 and a medical device 2 to be decontaminated are located at a decontamination device 24. In this example, the contaminated medical device 2 is contained within an interior space 12. The container 1 is sealed. In this example, the sealed container is in an unsealed state. The lid 14 includes perforations that allow air to enter or exit the interior space of the container. The container 1 is located at an inlet 26. A reader 38 reads the container's identification 34. In this example, a stack of containers 1 is located at the inlet 26. Therefore, the next container containing the device 2 to be decontaminated can be placed on top of the stack and await processing by the decontamination device 24.

[0140] In this example, processor 40 retrieves a record associated with identifier 34 of container 1 from memory 42. In this example, the record includes data representing processing instructions for decontaminating container 1. The data representing the processing instructions can be displayed on user interface 44. For example, the user interface can display a cleaning cycle retrieved from the record. It should be understood that it is possible for user interface 44 to allow manual operation of processing instructions. Alternatively, processor 40 may not retrieve processing instructions from memory 42, and user interface 44 may prompt the user to enter processing instructions for the container.

[0141] Container 1 at the bottom of the stack engages container handling device 28. Here, container handling device 28 rotates container 1 from a horizontal orientation at the bottom of the stack to a vertical orientation. It will be appreciated that deviations from a precise vertical orientation are possible. In this example, container 1 is moved above first chamber 30A while remaining in its closed position. Container 1 is then lowered into first chamber 30A. It will be appreciated that the generally elongated medical devices 2 are positioned in an upright position, with their longitudinal axes substantially vertical.

[0142] Once in the first chamber (or upon entering the first chamber or before entering the first chamber), the first cover 14 is moved away from the first opening 8, and the second cover 20 is moved away from the second opening 18. The container 1 is now in the open first chamber 30A. The interior surface of the container and the one or more instruments contained therein can be washed. It should be understood that in this example, the exterior surface of the container can also be washed.

[0143] In this example, after washing in the first chamber 30A, the container 1 is removed from the first chamber 30A. Here, in the process of lifting the container 1 out of the chamber 30A or before, the container 1 is closed again. Thus, a washed closed container is provided at this point. In this example, the container 1 is transported above the second chamber 30B. Once in the second chamber 30B (or when entering the second chamber or before entering the second chamber), the first cover 14 moves away from the first opening 8, and the second cover 20 moves away from the second opening 18. Now, the container 1 is in the second chamber 30B in an open state. The inner surface of the container and the one or more instruments accommodated therein can be washed. It should be understood that, in this example, the outer surface of the container can also be washed.

[0144] In this example, after washing in the second chamber 30B, the container 1 is removed from the second chamber 30B. Here, before or during the process of lifting the container 1 outside the chamber 30B, the container 1 is closed again. Thus, a washed, closed container is provided at this point. In this example, the container 1 is transported above the third chamber 30C. Once in the third chamber 30C (or when entering the third chamber or before entering the third chamber), the first cover 14 moves away from the first opening 8, and the second cover 20 moves away from the second opening 18. The container 1 is now in the open third chamber 30C. The inner surface of the container and the one or more instruments contained therein can be sterilized. It should be understood that in this example, the outer surface of the container can also be sterilized.

[0145] In this example, after sterilization in the third chamber 30C, the container 1 is removed from the third chamber 30C. Here, before or during the process of lifting the container 1 outside the chamber 30C, the container 1 is closed again. Thus, a sterilized closed container is provided at this point. In this example, the container 1 is transported above the fourth chamber 30D. Once in the fourth chamber 30D (or before or during entry into the third chamber), the first cover 14 moves away from the first opening 8, and the second cover 20 moves away from the second opening 18. Now, the container 1 is in the fourth chamber 30D in an open state. The inner surface of the container and the instruments contained therein can be dried. It should be understood that, in this example, the outer surface of the container can also be dried.

[0146] At this point, the container can be moved towards the outlet 32 ​​to provide a container containing sterilized but not sterilized medical instruments. Additionally, the perforation in the cover can be closed with a label as described below.

[0147] Alternatively, after drying in the fourth chamber 30D, the container 1 is removed from the fourth chamber 30D. Here, before or during the process of lifting the container 1 outside the chamber 30D, the container 1 is closed again. Thus, a dried, closed container is provided at this point. In this example, the container 1 is transported above the fifth chamber 30E. Once in the fifth chamber 30ED (or before or during entry into the third chamber), the first cover 14 moves away from the first opening 8, and the second cover 20 moves away from the second opening 18. The container 1 is now in the open fifth chamber 30E. The inner surface of the container and the one or more instruments contained therein can be sterilized. It should be understood that in this example, the outer surface of the container can also be sterilized. After sterilization in the fifth chamber 30E, the container 1 is removed from the fifth chamber 30E. Here, before or during the process of lifting the container 1 outside the chamber 30E, the container 1 is closed again. Thus, a sterilized, closed container is provided at this point.

[0148] The container can be moved toward a labeling unit 62. Labeling unit 62 is used to apply a label 64 to the container 1, here to the first lid 14. The label can close the perforation in the lid 14. Label 64 can include human-readable instructions. The human-readable instructions can, for example, include information about the decontamination process performed on the container (or its contents). This information can, for example, include a processing date and / or an expiration date.

[0149] In this example, the sixth processing step is evacuation. Here, the container can be evacuated at the labeling unit to a predetermined pressure, for example, below ambient pressure. The container is simultaneously closed while being evacuated, thus providing a sterilized, closed container. In this example, the container 1 is transported to the outlet 32. In this example, the container is placed at the bottom of the container stack at the outlet 32. The container can be retrieved from the outlet 32, for example, manually.

[0150] The purification method described above can be used as follows.

[0151] In one example, a predetermined set of medical instruments is associated with a predetermined container or a predetermined type of container. The predetermined set of instruments may be, for example, a set of instruments required to perform a certain procedure on a patient. The predetermined container may be an identifiable container, such as a container having a predetermined indicator, such as a number, letter, code, color, icon, or drawing, on its outer surface.

[0152] The association of a predetermined group of medical instruments with a predetermined container or a predetermined type of container is stored in the memory 42 of the decontamination device, or in a remote memory, and can be retrieved by the processor 40, for example, via a communication network such as an intranet or the Internet. The association is stored in a record in the memory. The record may include data representing the group of instruments and containers. The record may also include data representing a machine-readable identifier of the container. The record may include processing instructions (such as which decontamination process steps to follow and which parameters to use). For new associations, such records can be created using the user interface 44. The user interface 44 can also be used to modify existing associations.

[0153] In the above example, when the reader 38 identifies container 1, the record can be retrieved from the memory and the processing steps of the instrument in that container are automatically loaded into the processor 40. It will be understood that the user interface may provide the possibility to manually modify or overwrite the retrieved processing steps.

[0154] Once a medical device or set of medical devices is associated with a container of a type, the device or devices remain with the container of the type. For example, a container containing the decontaminated device or devices can be removed from the decontamination unit or from storage and brought to a processing space. In the processing space, the decontaminated device or devices are removed from the container (e.g., after checking for tampering) and used for the procedure. After the procedure, the contaminated device or devices are repositioned in the container. The container with the contaminated devices can then be presented to the decontamination unit again.
