Description

[0001] Dosing device for pharmaceutical purposes and method for operating a dosing device

[0002] The present invention relates to a dosing device for pharmaceutical purposes, which can be used with a system for processing a product, in particular a filling machine for filling containers with a pharmaceutical product, wherein the dosing device is arranged externally to the system.

[0003] Furthermore, the present invention relates to a method for operating a dosing device of the type described above.

[0004] In the filling machine, a pharmaceutical substance is filled into pharmaceutical containers, which can be, for example, vials, syringes, cartridges, or ampoules. The containers can be rigid or non-rigid. In this example, the pharmaceutical product is a fluid, specifically a liquid.

[0005] It is known that a dosing device is used with the filling machine, with the product being provided outside a chamber of the filling machine. A fluid line is fed through a defined connection device (e.g. an A / B port or RTP, rapid transfer port) and dosed into the containers in the filling machine. A conveying unit of the dosing device, for example, is used to dose the product. For example, the use of hose pumps (peristaltic pumps) is known, with which the liquid product can be conveyed in a dosed manner through a hose-shaped fluid line. In this context, the use of single-use equipment for the hose line, product containers and filling needles is known.

[0006] In practice, complying with hygiene requirements proves to be a challenge. Typically, the interior of the filling machine operates under a high cleanliness standard (e.g., GMP Type A), whereas the dosing device is located in a lower cleanliness environment, such as GMP Type C.

[0007] The object of the present invention is to provide a dosing device for pharmaceutical purposes and a method for operating such a dosing device which can be used in a variety of ways, in particular with regard to compliance with hygiene requirements.This object is achieved by a dosing device according to the invention for pharmaceutical purposes, comprising a closed container which has a wall and an interior space enclosed by the latter, at least one connection device for connecting the dosing device to a pharmaceutical system for processing a particularly liquid pharmaceutical product, wherein the at least one connection device is integrated into the wall and comprises at least one closing element for selectively closing an opening, a chassis for moving the dosing device on a support surface and at least one dosing tool in the interior space, which has a fluid line for guiding the product and a dosing unit for dosing and / or conveying the product through the fluid line, wherein the fluid line can be led out of the interior space when the at least one closing element is open.

[0008] The dosing device according to the invention comprises a closed container with an interior space and a chassis for moving the dosing device on a support surface. This makes it possible to preparatory equip the dosing device for its intended use with the system for processing the product, in particular the filling machine. The dosing device can be equipped separately from the system, whereupon the dosing device is moved to the system and the fluid line is guided from the interior of the container into the system via the open at least one closing element of the connecting device. Alternatively, equipment can also be carried out directly at the dosing device's place of use on the system. At least one dosing tool is provided in the interior space, which comprises the fluid line and a dosing unit.The dosing unit allows the provided product to be dosed and / or conveyed in a targeted manner and thus introduced into the system through the fluid line.

[0009] Alternatively or in addition to the at least one connection device via which the fluid line can be led out of the interior, the dosing device can comprise at least one connector device, preferably in a standardized and / or sterile design. For example, the fluid line in the interior is connected to the connector device, and an external fluid line of the system can be connected to the connector device on the outside. The connector device eliminates the need to open the container when the dosing device is connected to the system. The above design allows the dosing device to be preconfigured for the respective application. For example, a pre-sterilized or decontaminated dosing tool can be introduced into the previously sterilized or decontaminated interior in order to meet the necessary hygiene requirements.

[0010] Alternatively or additionally, it is preferably conceivable that non-sterile or non-decontaminated dosing tools are introduced into the non-sterilized or non-decontaminated interior space and that the interior space, including the dosing tools contained therein, is subsequently sterilized or decontaminated.

[0011] The setup and, in particular, the insertion of dosing tools into the interior can be accomplished in different ways. For example, a stationary chamber is operated, to which the mobile dosing device is docked and in which the dosing tool is accommodated. This can be sterile or decontaminated, or otherwise non-sterile or non-decontaminated. After undocking, the dosing device can be moved to the system and used.

[0012] Alternatively or additionally, it may be provided, for example, that a mobile chamber containing the dosing tool is transported to the location of the dosing device and docked to it. After equipping, the mobile chamber is removed, and the dosing device can be used on the system.

[0013] It is particularly advantageous if the dosing device is designed such that existing dosing tools can be operated with the dosing device. Accordingly, the dosing device is preferably adaptable to different dosing systems, whereby, for example, various dosing units, fluid lines, or other dosing tools of known types can be used selectively. In the present case, a dosing tool can be considered to be, in particular, an object that can be used to dose the product during the intended use of the dosing device, whereby the dosing tool can, in particular, have product contact.

[0014] Preferably, there is the possibility of multiple use of dosing tools.

[0015] The at least one connection device can be designed in different ways. For example, the use of a standardized port, in particular an A-port or a B-port, is conceivable. For example, an RTP (Rapid Transfer Port) is used for docking to the system. Overall, connection devices of any type are conceivable, specifically enabling an aseptic connection between the system and the dosing device. The connection device can be single-walled, with one closing element, or multi-walled, for example, double-walled with two closing elements.

[0016] With regard to compliance with hygiene requirements, it is advantageous if the container is or forms an isolating device, in particular with a defined atmosphere in the interior.

[0017] For example, the container may have a RABS feature (RABS, Restricted Access Barrier System).

[0018] The container is preferably liquid-tight and / or gas-tight when at least one connection device is closed.

[0019] The above properties allow in particular the use of the dosing device for processing highly active and / or toxic substances.

[0020] Conveniently, the degree of cleanliness in the interior can be set according to a specification, for example GMP Type A, B or C.

[0021] In order to provide and / or comply with the necessary hygiene requirements, it is advantageous if the dosing device can be decontaminated and / or sterilized in whole or in part, at least in the interior, including objects accommodated therein and specially accommodated dosing tools.

[0022] For example, the dosing device has a decontamination and / or sterilization device in its interior. Sterilization can be achieved, for example, with steam, and decontamination with H2O2.

[0023] For sterilization and / or decontamination via an external sterilization device and / or decontamination device, at least one connection element or transfer element can be provided on the wall to introduce a medium into the interior. This eliminates the need for an internal sterilization device and / or decontamination device. The at least one connection element allows the connection of a fluid line, while the transfer element, for example, allows the passage of a fluid line. Alternatively or additionally, the connection element can be designed for docking a unit for introducing material for decontamination or sterilization, for example, an autoclave, an F^Ch lock, or a UV lock.

[0024] As a dosing tool, a fluid line and a dosing unit are accommodated in the interior, whereby more than one fluid line and / or more than one dosing unit can be provided.

[0025] The at least one dosing tool may further comprise at least one container for holding the product, to which a fluid line is connected. The container may, in particular, be a bag.

[0026] Advantageously, the dosing device comprises a holding element in the interior for the defined arrangement and in particular suspension of the container.

[0027] The container and in particular bag can be a product bag or a batch bag.

[0028] The at least one dosing tool can comprise a filter element connected into the fluid line, in particular a sterile filter.

[0029] For example, the fluid line is connected to an outlet of the container, with the filter connected to the fluid line.

[0030] Overall, the equipment of the dosing device can depend on the user-specific and product-specific requirements and can preferably be adapted.

[0031] The dosing device can comprise a further fluid line as a dosing tool, wherein a feedthrough device for the further fluid line from the outside into the interior is arranged in the wall and the further fluid line is connected to an inlet of the container. Such a design is used, for example, when two containers are used. For example, a preparation bag is provided outside the container, from which the product is transferred through the further fluid line into the interior into a product bag received therein, from which the product is conveyed through the fluid line by means of the dosing unit. The feedthrough device is preferably designed to be sterile. This can be, for example, an aseptic liquid transfer port (SART or AT port).

[0032] The filter element can be connected to the further fluid line inside the container or can be connected to the further fluid line outside the container.

[0033] For example, if only one fluid line is used, the dosing device can comprise a feedthrough device in the wall for passing the fluid line from the outside into the interior, wherein the feedthrough device can be designed as described above. Such a configuration is used, for example, with only one container. For example, the product bag to which the fluid line is connected is arranged outside the container.

[0034] From the above, it follows that the dosing device may comprise, outside the interior space, a container for receiving the product, to which the further fluid line or the fluid line is connected.

[0035] The dosing device can, for example, comprise a holding element outside the interior for the defined positioning and, in particular, suspension of the container. The holding element is preferably arranged and fixed to the container and can be moved together with it.

[0036] The at least one connection device and the feedthrough device can, for example, be arranged on opposite sides of the container.

[0037] The dosing device can preferably comprise a receptacle in the interior for detachable mounting of the dosing unit. When equipping the dosing device, for example, a suitable dosing unit can be inserted and mounted on the receptacle.

[0038] A connection element for providing electrical power to the dosing unit is preferably arranged outside the interior. Alternatively or additionally, the dosing device can comprise a power supply device.

[0039] A connection element for a control and / or signal line is preferably arranged outside the interior space to control and / or regulate the operation of the dosing unit. An optional control device for the dosing device is advantageously arranged outside the interior space.

[0040] Advantageously, at least one adapter element is provided for the detachable mounting of various dosing units on the holder. This allows for versatile design with regard to user-specific and product-specific requirements and the corresponding adaptation of the dosing device.

[0041] The dosing unit may be, for example, a peristaltic pump, a rotary piston pump, a time-pressure dosing unit and / or a multi-dosing unit.

[0042] It may be advantageous if the interior space is divided into a first zone and a second zone by means of a dividing element, such as a partition wall, with the first zone having a higher degree of purity than the second zone. Separate zones can be provided, for example, to process products with special properties, such as toxic products.

[0043] For example, it can be provided that the fluid line and a filling needle connected to the fluid line are arranged entirely or partially in the first zone and / or that a container for holding the product is arranged in the second zone. The dosing unit can be arranged, for example, in the first zone or in the second zone.

[0044] In one embodiment of the invention, at least one glove opening for a user can be provided on the container.

[0045] The wall is advantageously designed to be transparent, at least in sections, to allow a user to see into the container.

[0046] In a preferred embodiment of the invention, the at least one dosing tool can comprise at least one filling needle connected to the fluid line, which is arranged in the interior. With at least one connection device open, the filling needle can be inserted into the system and used to fill the containers.

[0047] The dosing device can be provided with a holding part in the interior for the defined positioning and, in particular, suspension of the filling needle. The holding part can be arranged, for example, on at least one closing element, which can be pivoted out of the interior when the at least one connection device is opened. This allows, for example, the filling needle to be moved into the interior of the system when the closing element is opened, so that it can be grasped there more easily, for example, by a robotic device and / or manually.

[0048] The holding part can preferably be designed to be variable in size or length, and can be transferred from a storage position to a use position, in which the filling needle can be spaced from the container when at least one closing element is open. This improves the handling of the filling needle during insertion or for insertion into the interior of the system. The holding part can, for example, be telescopic, extendable, foldable, or the like. A drive for the holding part can be provided. The use of a scissor-type hoist or scissor-type gate to which the filling needle is held is conceivable.

[0049] The dosing device can comprise a further connection device integrated into the wall with at least one further closing element, wherein the connection devices are arranged, for example, on opposite sides of the container. The further connection device can be designed in a variety of ways. For example, the use of an A / B port, an RTP, or similar is conceivable. Advantageously, an aseptic connection to the container is possible via the further connection device.

[0050] The additional connection device allows, for example, the dosing device to be connected to a stationary chamber. Alternatively or additionally, the use of a portable chamber is conceivable, which is brought to the dosing device and from which the dosing tool is removed.

[0051] The dosing device can comprise a gassing device that includes a container for gas in the interior, a gas line connected to it, and preferably a nozzle-shaped outlet element on the latter. The gas line can be led out of the interior when at least one closing element is open. For example, this allows pre-gassing, filling gassing, and / or post-gassing during filling of the product. A separate gassing path can thus be eliminated. In a preferred embodiment, the dosing device can comprise an air conditioning device for adjusting a temperature and / or humidity level in the interior.

[0052] Alternatively or additionally, the dosing device can comprise a ventilation device for providing a preferably defined air flow in the interior space. For example, a laminar air flow (LF) is provided. The ventilation device can be arranged inside the interior space or outside the interior space, with the air flow passing through an opening in the wall. The ventilation device can be designed as an overpressure device or as a negative pressure device.

[0053] The dosing device can comprise a weighing element arranged in the interior, the signal of which can preferably be used for dosing the product. For example, the holding element for the container is provided with a weighing element. The weighing element can be used to determine the contents of the container or a change in the contents based on its weight, thereby determining and / or controlling the dosing.

[0054] The dosing device can, for example, be operated manually by a user.

[0055] The chassis may be provided with a drive system.

[0056] In a favorable embodiment of the invention, the dosing device is designed to be self-propelled and self-steering, and can move independently across the installation surface without user intervention. Accordingly, the dosing device can be designed to be robotic.

[0057] As mentioned at the beginning, the present invention also relates to a method.

[0079] The drawing shows an advantageous embodiment of the dosing device according to the invention, designated overall by the reference numeral 100, with which the method according to the invention can be carried out according to a preferred embodiment.

[0080] The dosing device 100 is versatile and is used with a system 102 for processing a pharmaceutical product. In this case, the product is a liquid that can be provided by the dosing device 100 and, in particular, introduced into the system 102 in a metered manner. In the system 102, pharmaceutical containers, for example, vials, syringes, cartridges, or ampoules, are filled with the product. The system 102 comprises a wall 103.

[0081] The dosing device 100 can be adapted in a variety of ways, depending on the user-specific and product-specific requirements and the product to be processed. It is particularly advantageous that various hygiene requirements can be met. Preferably, different purity levels can be achieved, for example, GMP Type A, B, or C. It is preferably possible to configure the dosing device with the container as an isolator device, with a defined atmosphere in the interior. The container can have a RABS property and, in particular, be liquid-tight and / or gas-tight when closed.

[0082] Overall, the dosing device 100 forms in particular a closed containment which is mobile, in the present case movable on the installation surface 110 and can be moved towards and away from the system 102.

[0083] Figures 1 to 3 show the dosing device 100 in an exemplary configuration and are explained below.

[0084] The dosing device 100 comprises a container 104. In this case, the container 104 is arranged on a base 106, for example, in the form of a frame. A chassis 108 for movement on a support surface 110 is arranged on the base 106. In this case, the chassis 108 comprises rollers 112 that are not driven. In the present example, the dosing device 100 can be moved manually on the support surface 110 by a user 114.

[0085] Alternatively or additionally, it is conceivable that the chassis 108 has a drive 116.

[0086] Alternatively or additionally, it is conceivable that the dosing device 100 is designed to be self-propelled and self-steering and can be moved autonomously on the installation surface 110 in a robotic manner.

[0087] To control and / or regulate the operation of the dosing device 100, for example during autonomous operation, a control device 118 is provided, which is advantageously arranged outside the container 104.

[0088] For example, the control device 118 is accommodated in a housing 120 which is held on the base 106.

[0089] For example, a power supply device 122 can be accommodated in the housing 120. Outside the container 104, for example, on the base 106 or on the housing 120, a connection element 124 for connecting an external power supply device can be arranged alternatively or additionally.

[0090] In the present exemplary embodiment, the container 104 is cuboid-shaped, although this is not limiting. The container 104 comprises a wall 126 that encloses an interior space 128. The wall 126 can be fully or partially transparent to allow the user 114 to view the interior space 128.

[0091] It may be provided that the container 104 comprises a removable wall or a removable section of a wall (for example in the manner of a removable or hinged lid) in order to open the container and to reach into the interior 128.

[0092] The dosing device 100 can comprise at least one glove opening 130 on the container 104, through which the user 114 can access the interior 128 in a sterile manner. In the present case, two glove openings 130 are provided. The wall 126 is advantageously transparent in the wall accommodating the glove openings 130.

[0093] The dosing device 100 can be connected to the system 102, particularly in an aseptic manner. For this purpose, a connection device 132 with an inwardly opening closing element 134 is provided on the system 102.

[0094] The dosing device 100 is positioned on the system 102 such that a connecting device 136, integrated into the wall 126 and comprising a closing element 138, is aligned with the connecting device 132. The closing element 138 can be opened to expose an opening 139 in the wall 126, and can preferably be pivoted into the interior space 140 of the system 102. In this way, the interior space 128 can communicate with the interior space 140.

[0095] The connection devices 132, 136 are preferably standardized, for example designed as A / B ports or as RTP ports.

[0096] The dosing device 100 can comprise a further connection device 142 integrated into the wall 126. Such a connection device 142 is shown in the drawing, with the connection devices 136, 142 being arranged on opposite sides of the wall 126. This can prove advantageous, for example, for handling the dosing device 100 to maintain a defined work process. Provision can be made for dosing tools to be introduced into the interior 128 from one side via the connection device 142 and removed from the opposite side via the connection device 136.

[0097] The connecting device 142 also comprises a closing element 144. When the closing element 144 is open, an opening 145 in the wall 126 is exposed.

[0098] The connection device 142 is preferably designed in a standardized manner, for example as an A / B port, for example as an RTP port.

[0099] In the present embodiment, the dosing device 100 comprises a feedthrough device 147 integrated into the wall 126. A fluid line can be routed through the feedthrough device 147 in a sterile manner from the outside to the inside into the interior space 128. For example, the feedthrough device 147 is designed in a standardized manner, such as an aseptic fluid transfer port (SART or AT port).

[0100] Dosing tools for dosing the product, in particular a liquid product, can be accommodated in the interior space 128. It is provided that at least one dosing unit and at least one fluid line are accommodated. The dosing tools, in particular in the interior space 128, can comprise, for example, the following: at least one dosing unit, at least one fluid line, at least one container for the product, at least one filter element, and at least one filling needle connected to the fluid line. Various equipment of the dosing device 100 will be discussed below.

[0101] First, however, further optional features of the dosing device will be presented as examples.

[0102] A sterilization device 148, a decontamination device 150, a ventilation device 152 and an air conditioning device 154 may be provided.

[0103] The devices 148, 150, 152 and 154 can be arranged wholly or partially in the interior 128 or wholly or partially outside the container 104. Figure 3 shows the devices 148, 150, 152 and 154 in the interior 128 by way of example. In an arrangement outside the container 104, at least one connection element or the like can be provided in the wall 126 in order to pressurize the interior 128 in the desired manner.

[0104] The sterilization device 148 and the decontamination device 150 enable, for example, sterilization or decontamination of the interior space 128 and the material arranged therein, in particular the dosing tools. Steam or H2O2, for example, can be used for sterilization or decontamination.

[0105] A defined flow, for example a laminar flow, can be generated in the interior space 128 via the ventilation device 152.

[0106] For example, the temperature and / or a degree of humidity in the interior 128 can be adjusted via the air conditioning device 154.

[0107] The devices 148, 150, 152 and 154 are preferably connected to the control device 118 for controlling and / or regulating the operation.

[0108] As can be seen particularly from Figures 1 to 3, a dosing unit 156, which is configured here as a peristaltic pump 158, is arranged in the interior 128. To drive the dosing unit 156, a drive unit 160 can be arranged in the interior 128 or guided into it, preferably in a pharmaceutically acceptable configuration. The drive unit 160 is supplied with electrical energy, for example, by means of the power supply device 122 or externally via the connection element 124.

[0109] Conveniently, the drive unit 160 forms a receptacle 162 to which various dosing units 156 can be detachably mounted, depending on the use of the dosing device 100. For example, a respective adapter element 164 is provided to adapt the respective dosing unit 156.

[0110] The dosing unit 156 is in this case a dosing tool 166 which is used for dosing and / or conveying the liquid product.

[0111] As a further dosing tool 166, a fluid line 168 is provided in the interior space 128, which is designed in particular as a hose line and is inserted into the peristaltic pump 158. As a further dosing tool 166, a filling needle 170 connected to the fluid line 168 is provided. The product can be filled into the containers via the filling needle 170.

[0112] In this case, a container 172 in the form of a bag 174 is provided as a further dosing tool 166. The fluid line 168 is connected to an outlet of the bag 174, is guided through the peristaltic pump 158, and has the filling needle 170 at its end.

[0113] For the defined arrangement of the filling needle 170 in the interior space 128, the dosing device 100 comprises a holding part 176. For example, the filling needle 170 is held on the holding part 176 by force and / or form locking.

[0114] It may be advantageous if the holding part 176 is secured to the closing element 138. When the closing element 138 is opened, the holding part 176, with the filling needle 170 held thereon, is moved into the interior 128 of the system 102 and can thus be grasped more easily.

[0115] A holding element 178 for the defined positioning of the bag 174 is preferably arranged in the interior space 128. In the present case, the holding element 178 is fixed to the wall 126, and the bag 174 is suspended from the holding element 178.

[0116] For example, a weighing element 180 can be provided on the holding element 178, which weighing element 180 is designed as a beam balance. This can be used, in particular, to determine a change in the mass of the bag 174 and thereby control and / or regulate the dosing process. The weighing element 180 can be coupled to the control device 118.

[0117] As a further dosing tool 166, the dosing device 100 in the present example comprises a further fluid line 182, which is designed as a hose line. The fluid line 182 is connected to an inlet of the bag 174, and is guided from the outside through the feedthrough device 147 into the interior space 128.

[0118] A filter element 184, which is in particular a sterile filter, is connected to the fluid line 182 as a further dosing tool 166. The filter element 184 is arranged in the interior space 128. The further fluid line 182 is connected to the outlet of a further container 186, which is designed as a bag 188 in this case.

[0119] For the defined positioning of the bag 188, the dosing device 100 comprises a holding element 190. In the present example, the bag 188 can be suspended from the holding element 190. The holding element 190 is preferably fixed to the container 104.

[0120] In the present exemplary configuration of the dosing device, the bag 188 serves as a hub for storing the product. The product flows through the fluid line 182 into the bag 174, which serves as the product bag. From the bag, the product flows through the fluid line 168 to the filling needle 170 and can be filled into the containers.

[0121] The dosing device 100 is positioned on the system 102 during use. The connecting devices 132, 136 are aligned to dock the dosing device 100. With the closing elements 134, 138 open, the fluid line 168 with the filling needle 170 can be inserted into the interior space 128. This is shown in dashed lines in Figure 2. The filling needle 170 can be grasped, for example, by a robotic device or by a user.

[0122] Figures 4 to 6 show different types of equipment of the dosing device 100, such as those that can be used, for example, when processing a different product or for different user requirements. Only the differences compared to the equipment shown in Figures 1 to 3 are explained.

[0123] In the equipment variant according to Figure 4, the filter element 184 is also connected into the fluid line 182, but is arranged outside the container 104.

[0124] In the equipment variant according to Figure 5, the bag 174 in the interior 128 is omitted. Instead, only the outer bag 188 is present as a product bag. Only the fluid line 168 is used, which is routed from an outlet of the bag 188 through the feedthrough device 147 and into which the filter element 184 is connected.

[0125] In the equipment variant according to Figure 6, the outer bag 188 is omitted. The fluid line 182 is omitted. The fluid line 168, into which the filter element 184 is connected, is connected to the outlet of the bag 174, as in the variant according to Figures 1 to 3. Figure 7 shows an embodiment of the holding part 176 that is designed to be variable in length. It shows a view from the side of the system 102, in which the filling needle 170 is already inserted into the interior space 128.

[0126] The holding part 176 is designed to be foldable and, in the present example, comprises three segments 192, 193, and 194. The segments 192, 193 are pivotally connected to one another at a joint 195. Similarly, the segments 193 and 194 are pivotally connected to one another at a further joint 196.

[0127] The filling needle 170 is held in the present case on the segment 194, and the fluid line 168 is guided along the holding part 176.

[0128] Figure 7 shows the unfolded position of the holding part 176. As long as the holding part 176 is arranged in the closed container 104, the holding part 176 is folded (not shown). To unfold or fold the holding part 176, the segments 192 to 194 can be pivoted relative to one another.

[0129] The dosing device 100 may comprise a gassing device 198, which is preferably arranged in the interior space 128 and can be controlled, for example, by the control device 118 (Figure 3). The gassing device 198 may be configured for pre-gassing, intermediate gassing, and / or post-gassing of the container to be filled.

[0130] The gassing device 198 may, for example, comprise a container 200 for gas, a gas line 202 and at least one outlet element 204 which is nozzle-shaped.

[0131] Figure 7 schematically shows an outlet element 204. The outlet element 204 is held on the segment 194.

[0132] Two outlet elements 204 are shown in the embodiment of the holding part 176 according to Figure 8.

[0133] In the variant according to Figure 8, the outlet elements 204, as well as the filling needle 170, are held on a holding member 206 of the holding part 176. The holding member 206 is secured at its end to an extension member 208, which in this example comprises a scissor pull 210. The scissor pull 210 is shown in Figure 8 in the extended position, in which it projects into the interior 128 of the system 102.

[0134] In the retracted position not shown in the drawing, the scissor pull 210 is arranged in a receptacle 212 within the opening 139, so that the holding member 206 is also positioned within the container 104 when the closing element 138 is closed.

[0135] Figures 9 to 11 schematically show a setup process for equipping the dosing device 100 according to the task to be performed. The setup variant shown in Figure 5, which has already been explained, is shown as an example.

[0136] To equip the dosing device 100, various chambers 214, 216, 218 can be connected to the container 104, in particular to the connection device 142. For a preferably aseptic connection, the chambers 214, 216, 218 advantageously comprise a connection device that can be aseptically coupled to the connection device 142.

[0137] In the present case, the chambers 214, 216, and 218 differ in that the respective contents of the dosing tools 166 vary. It is assumed here that the dosing unit 156, for example, the peristaltic pump 158, is already located in the interior 128 of the container 104.

[0138] The chamber 214, which is used in the assumed example and whose contents are or were introduced into the container 104 in Figures 10 and 11, contains the fluid line 168 with the filling needle 170 and the filter element 184. After docking (Figure 10), these dosing tools 166 are introduced into the interior 128, and then the chamber 214 is decoupled. The fluid line 168 is guided through the feedthrough device 147 and connected to the bag 188 (Figure 11).

[0139] For an equipment variant not explained below, for example, the chamber 216 can be used, in which, in addition to the aforementioned dosing tools 166, the dosing unit 156 is introduced into the interior 128 as a further dosing tool.

[0140] In a configuration variant, also not further explained, the bag 174 is additionally introduced into the interior 128 via the chamber 218. In this example, the fluid line 168 remains in the interior 128, for example. Figures 9 to 11 show the chambers 214 to 218 in a movable form, which are moved toward the dosing device 100. The chambers 214 to 218 are designed to be movable, are connected to the dosing device 100, and then removed from it again.

[0141] In the illustration shown, the dosing device 100 is already positioned in the desired position on the system 102, although the closing elements 134, 138 are not yet open. It is understood that the dosing device 100 can be positioned at a distance from the system 102 during the finishing processes.

[0142] Alternatively or in addition to the mobile chambers 214 to 218, it is conceivable that the dosing device 100 is moved on the installation surface 110 of a stationary chamber 220 in which the dosing tools 166 are accommodated and which is shown schematically in Figure 9.

[0143] Depending on the application, it may be provided that the dosing tools 166 to be inserted are already sterilized or decontaminated or that the sterilization or decontamination only takes place in the interior space 128.

[0144] For example, the following steps are conceivable when operating the dosing device 100:

[0145] Provision of pre-sterilized dosing tool (single-use) 166 via an RTP or other connection device in the previously sterilized or decontaminated chamber 214 to 220, installation through the glove openings 130 by the user 114, closing and undocking of the container 104, connection to the system 102, opening the connection device 132, 136, insertion of the filling needle(s) 170 and start of filling;

[0146] Inserting the non-sterile dosing tool 166 into the non-sterilized or non-decontaminated container 104, installing the dosing tool 166, closing the container 104 and sterilizing or decontaminating at least the interior 128 with its contents, connecting it to the system 102, opening the connecting device 132, 136, inserting the filling needle(s) 170 and starting the filling process; Docking of the previously internally sterilized or decontaminated container 104 to a sterile external chamber or setup unit 214 to 220 via a connection device, installation through glove openings 130 of the external chamber or setup unit 214 to 220, closing and undocking of the container 104, connection to the system 102, opening the connection device 132, 136, insertion of the filling needle(s) 170 and start of filling;

[0147] Docking of the non-sterilized or decontaminated container 104 to a non-sterile chamber or external setup unit 214 to 220 via a connection device, sterilization or decontamination of the container 104 and the chamber or setup unit 214 to 220 together, installation of the dosing tool 166 through glove openings of the chamber or external setup unit 214 to 220, closing and undocking of the connection device, connection to the system 102, opening the connection device 132, 136, insertion of the filling needle(s) 170 and start of filling;

[0148] Docking of the non-sterilized or decontaminated container 104 to a non-sterile chamber or external setup unit 214 to 220 via a connection device, installation of the dosing tool 166, sterilization or decontamination of at least the interior 128 with contents, closing and undocking of the connection device, connection to the system 102, opening of the connection device 132, 136, insertion of the filling needle(s) 170 and start of filling.

[0149] It proves advantageous that the container 104 can maintain its hygienic properties for an extended period of time. For example, the dosing device 100 can be prepared and stored or temporarily parked well in advance of use, with it only being moved to the system 102 at a later time.

[0150] Figure 3 shows, via a dashed line 222, an optionally present separating element 224 in the interior space 128. The separating element 224 can, for example, be a partition wall 226 with at least one opening.

[0151] The interior space 128 is divided into a first zone 228 and a second zone 230 via the separating element 224, with the first zone 228 having a higher purity class than the second zone 230. In the present example, the fluid line 168, the filling needle 170, and the dosing unit 156 are arranged in the first zone 228. The fluid line 168 is guided through the separating element 224 into the second zone 230, in which the bag 174 and the filter element 184 are arranged.

[0152] The interior space 128 can have different purity levels depending on requirements. For example, a GMP A purity level is conceivable for highly active and toxic substances. On the other hand, a GMP B or GMP C purity level is also conceivable. It is advantageous that the respective purity level can be achieved as needed for the dosing device 100, depending on the application, making the dosing device 100 particularly versatile.
