Description

[Technical Field]

[0001] The present invention relates to a functional module for guiding a storage container to a dosing station arranged in a processing chamber, the functional module being provided for aseptically filling the container with a liquid therein. The storage container is provided to be arranged in an installation chamber, and the storage container and the processing chamber are surrounded by a housing. The functional module includes an element support, a functional element for installation on the element support, and a medium line provided for connecting the functional element. The present invention also relates to a method for guiding the envisaged functional module to the dosing station. [Background technology]

[0002] Until now, the components of functional modules for dosing stations in filling machines for aseptically filling containers, especially pharmaceutical vials, with liquids, had to first be transferred to the processing chamber of the containment vessel using a rapid transfer port (RTP). The components are then assembled in the processing chamber, which requires manual intervention in the processing chamber. This process is time-consuming, involves risks related to errors and the introduction of impurities, and is costly in terms of plant technology. Summary of the Invention [Problem to be solved by the invention]

[0003] In view of the incomplete solutions provided to date in the technical fields outlined in the prior art, the present invention aims to at least reduce the manual handling in the processing chambers, thereby making the work process more efficient in terms of time consumption, less prone to errors, improving quality, and reducing the complexity of the equipment. This applies in particular to eliminating the risk of contamination due to manual handling in the processing chambers. To this end, it is necessary to develop a dedicated device and propose a method using this device. [Means for solving the problem]

[0004] The envisioned functional module is designed to guide a storage container to a dosing station located in a processing chamber, where the container is aseptically filled with a liquid. The storage container is provided for placement in an installation chamber, and the storage container and processing chamber are enclosed by a housing. The functional module includes an element support, a functional element for installation on the element support, and a medium line connected to the functional element. The assembly consisting of the element support, the functional element housed therein, and the medium line connected thereto can be moved from an introduced starting position to an unfurled working position at the dosing station through a transfer port leading to the processing chamber.

[0005] In the following, particularly advantageous details of the functional module are described. The functional module is used for the aseptic filling of pharmacological or toxic liquids into a plurality of containers arranged in a single batch. When handling oxygen-sensitive liquids, an inert gas blanket, for example nitrogen, is used. The containment container housing comprises a back wall defining a processing chamber. The transfer port is formed by an opening in a profiled part of a flange connection attached to the back wall.

[0006] In particular, in a first embodiment of the functional module, the element support has a front piece rigidly arranged at the front and an end piece rigidly arranged at the rear. The front piece stops in the transfer port in the introduced starting position. The end piece, on the other hand, is configured to abut against the transfer port in the unwound working position and provide access to the media line leading to the functional module. The functional module installed at the transfer port, in the introduced starting position, projects into a transfer cell adjacent to the process chamber. The transfer port forms an interface between the process chamber and the transfer cell. The outer wall belonging to the housing of the containment vessel and defining the transfer cell towards the installation chamber is provided with: a) a transfer device preferably configured as a rapid transfer port (RTP) that allows pre-sterilized functional elements and media lines to be safely fed into the transfer cell; and b) Usually a pair of glove ports for carrying out operations, in particular assembly operations, ie the loading of the element supports with the functional elements and the media lines to be connected thereto, whilst maintaining a sterile atmosphere in the transfer cell.

[0007] In particular, in the second example of a functional module, this has: a) a gas-tight container with a sterile interior; and b) A sterilized assembly of components mounted in a container, comprising an element support, functional elements housed therein, and media lines connected thereto to external connector(s), as well as a front piece firmly positioned at the front of the element support.

[0008] In the introduced starting position, the assembly is in the container, and the front piece closes the passage of the container gas-tightly. To reach the working position, the assembly can first be moved together with the front piece out of the container through the transfer port to the processing chamber and then to the dosing station.

[0009] The functional modules include: a) one or more connectors located outside the container and connected to media lines from the inside of the container, the connector(s) being for connecting to at least one supply line; and b) An adjustment mechanism located outside the container for moving the assembly consisting of an element support with a front piece, a functional element housed by the element support, and a medium pipe connected thereto.

[0010] The functional module is mounted in the transfer port so that it can extend into the transfer cell adjacent to the processing chamber and into the installation chamber, or so that the entire functional module can freely extend into the installation chamber. The external connector(s) and the adjustment mechanism for moving the assembly consisting of the element support with the front piece, the functional element housed by the element support, and the medium lines connected thereto are accessible from the installation chamber. The transfer cell can open towards the installation chamber, for example, by a wall opening in the outer wall.

[0011] In particular, in the use of the first example of the functional module, the following main method steps are performed: a) providing an element support with an attached functional element and a medium line connected thereto outside the processing chamber; and b) Guiding the assembled component, consisting of the element support, the functional element housed thereby, and the media lines connected thereto, in a decontaminated or sterile state from the starting position where it was introduced through a sealed transfer port provided in the housing wall defining the processing chamber to the working position where it is unloaded into the dosing station.

[0012] Particularly advantageous details of a method for using the first example of the functional module are described below: In a transfer cell adjacent to the processing chamber and hermetically closable toward the installation chamber, the element support with the functional elements and media lines is provided and assembled while maintaining aseptic conditions. When the element support is partially extended into the processing chamber, a front piece firmly seated in the front row on the element support opens a transfer port between the processing chamber and the transfer cell. In this position, a decontamination agent is introduced, preferably from the processing chamber side and simultaneously from the transfer cell side, thereby decontaminating the processing chamber, the transfer cell, and the element support. Subsequently, the pre-sterilized functional elements and media lines are fed into the transfer cell through the transfer device while maintaining aseptic conditions. Finally, the functional elements are attached to the element support and the media lines are connected to them using a glove port while maintaining a sterile atmosphere in the transfer cell.

[0013] In the starting position, the assembled assembly, including the element support, the functional element accommodated therein, and the media lines connected thereto, is located in the transfer cell, with the front piece of the element support located at the front end being positioned in the transfer port. To reach the working position, the assembled assembly is guided or supported in the form of a carriage and advanced from the transfer cell to the dosing station until the end piece located at the rear end of the element support abuts against the transfer port. The assembly is advanced to the working position by pushing it from the side of the transfer cell or by pulling it from the side of the processing chamber, for example, by using a robot installed in the processing chamber.

[0014] In particular, in the use of the second example of the functional module, the following main method steps are performed: a) providing a functional module, the functional module comprising: aa) a gas-tight container with a sterile interior; ab) a component group assembled and sterilized in a container, consisting of an element support with a front piece, functional elements accommodated by the element support, and medium lines connected thereto and leading to a common external connector or to each connector, wherein the component group is in a state where it is introduced into the container in the starting position, the front piece gas-tightly closing the passage in the container, and to reach the working position, the component group together with the front piece is first guided in the form of a carriage and unrolled from the container to the dosing station, b) sealingly placing the functional module in the transfer port in a starting position with the outer surface of the front piece facing the process chamber; c) decontaminating the treatment chamber and simultaneously the outer surface of the front piece; d) advancing the assembly to the dosing station to reach the working position, and finally e) connecting the supply lines to external connector(s), f) Process step e) can alternatively be carried out between process steps c) and d) or between process steps b) and c).

[0015] In the following, particularly advantageous details are given of the method for using the second example of the functional module. The functional module is installed in the transport port as follows: a) the functional module can extend into a transfer cell adjacent to the processing chamber and into the placement chamber, or the entire functional module can extend freely into the placement chamber; and b) An adjustment mechanism for moving the external connection part(s) and the component group consisting of the element support with the front member, the functional element housed by the element support and the medium pipe connected thereto is installed so as to be accessible from the installation chamber and / or the transfer cell.

DETAILED DESCRIPTION OF THE INVENTION

[0017] With reference to the accompanying drawings, the following will describe in detail the functional module of the present invention in two different examples and the assembly flow method therefor, as well as the establishment of operational readiness and the use of the functional module.

[0018] Further, the following provisions apply throughout the description: Where reference numbers are included in a figure for the purpose of clarifying the drawing but are not explained in the directly related description, reference is made to the preceding or succeeding figure description.

[0019] Figures 1A and 1B The containment vessel 9, here in the form of an isolator in the installation room 8, is surrounded by a housing 90 and is shown in its basic configuration for the purpose of illustrating the interior layout, existing walls, and equipment configuration. The front wall 910 typically has a transparent plate 911, and the rear wall 912 houses an exchange unit 95. The housing 90 further includes an upper roof surface 91, a lower base 92, a rear exterior wall 900 on which a transfer device 903 is installed, and first and second side surfaces 916, 918, which, together with the front wall 910 and rear wall 912, define the containment vessel 9 outward. The first side surface 916 has an inlet flow opening 917, while the second side surface 916 has an outlet flow opening 919. A projection 913 extends from the lower portion of the front wall 910 below the plate 911 into the installation room 8, and an intermediate floor 914, sloping obliquely downward, extends toward the lower region of the rear wall 912. Furthermore, a horizontal chamber divider 915 extends from an upper portion of the front wall 910 toward the rear wall 912 , from which horizontal upper and lower cell walls 901 and 902 extend toward the outer wall 900 .

[0020] Thus, the housing 90 and existing walls define a front region 94 and a rear chamber 99. The front region 94 comprises a roof chamber 98 separated above a chamber divider 915, a floor chamber 97 below an intermediate floor 914, and a processing chamber 93 between the roof chamber 98 and the floor chamber 97. Within the rear chamber 99, a transfer cell 96 is defined between an upper cell wall 901 and a lower cell wall 902. A transfer tool 903, advantageously configured as a rapid transfer port (RTP), on the rear outer wall 900 is used to securely transfer pre-sterilized components into the transfer cell 96. Additionally, glove ports 905, typically in pairs, are provided in the outer wall 900 to allow operations within the transfer cell 96 to be performed while maintaining a sterile atmosphere.

[0021] The equipment configuration of the storage container 9 includes a dosing station 3 installed in the processing chamber 93, where a functional module 2 (here a first example) is guided from a transfer cell 96 into its working position through a transfer port 260. The first example of the functional module 2 is the subject of the sequence of Figures 1A-5, the detailed description of which follows the actual assembly sequence and use of the device. A flange connection 20 mounted in a recess of the exchange unit 95 has the transfer port 260. The functional module 2 is rigidly but retractably mounted on the flange connection 20. The main component of the functional module 2 is the element support 23. To be introduced into the dosing station 3, the robot 1 has an operating mechanism 12, for example in the form of a gripper, guided by a pivotable arm 11. Advantageously, the foot 10 of the robot 1 is fixed to the rear wall 912 below the exchange unit 95.

[0022] Figures 2A and 2B Based on this pair of drawings, the main components of the functional module 2 are described, including: a) a flange connection 20 consisting of a first packing 21, a second packing 21' of smaller diameter, a third packing 27, a cover ring 22 and a shaped element 26 with a transfer port 260; b) a front piece 24 with a handle 240 fixed to it; c) an end piece 25 to which a handle 250 is fixed; and d) an element support 23 for mounting a functional element 230; belongs to.

[0023] Figures 3A and 3B This pair of drawings, for the sake of clarity only and which differ from the actual assembly flow, shows the assembled functional module 2 without the functional element 230 yet installed and without the medium line 231 connected, which is introduced into the dosing station 3 of the treatment chamber 93 through the transfer port 260. In the working position shown, the front piece 24 fixed to the element support 23 is advanced within the treatment chamber 93 and the end piece 25 at least partially closes the transfer port 260. The cover ring 26 of the flange connection 20 attached to the exchange unit 95 abuts against the exchange unit 95 from the side of the treatment chamber 93.

[0024] Figures 4A and 4B Furthermore, in the working position, for the sake of clarity but still not corresponding to the actual assembly sequence, the assembled functional module 2 is now fitted with the functional element 230, but the medium line 231 is not yet connected.

[0025] Figure 5 Once the functional module 2 with the functional elements 230 is assembled, the medium lines 231 are also connected to it, specifically directly to the openings of the functional elements 230. The functional module 2 is in its true working position, just as in reality, i.e., it is extended from the transfer port 260 to the treatment chamber 93 and into the dosing station 3, with the end piece 25 remaining in the transfer port 260 and at least partially sealing it.

[0026] First Example Functional Module Assembly Flow and Use Preparation and start-up of production involves the following steps: 1. An unattached element support 23, i.e. an element support 23 to which a functional element 230 has not yet been attached and to which a medium line 231 has not yet been connected, is moved from the introduced starting position to an intermediate position in which gas can flow between the processing chamber 93 and the transfer cell 96 of the partially open transfer port 260. 2. While in the intermediate position, decontamination of the process chamber 93 takes place, thus also extending to the transfer cell 96 through the partially open transfer port 260 while cleaning the periphery of the element support 23. 3. After decontamination of the process chamber 93, the element support 23 and the transfer cell 96, while maintaining clean room conditions, the pre-sterilized functional elements 230 and the media lines 231 are transferred into the transfer cell 96. The protective transfer of the pre-sterilized components into the transfer cell 96 is performed by the transfer device 903. 4. The element support 23 is returned to the starting position where it was introduced. That is, the element support 23 is in the transfer cell 96, the functional element 230 is attached to the element support 23, and the medium line 231 is connected to the functional element 230. This assembly operation is performed by the operator using the glove port 905 while maintaining a sterile atmosphere in the transfer cell 96. 5. Once processed and assembled, the now fully fitted element support 23 can be removed from the transfer cell 96 and pushed forward into the processing chamber 93 as far as the dosing station 3. 6. Advantageously by means of the handling mechanism 12 of the robot 1, containers, preferably open-topped vials, to be filled in particular with pharmacological liquids, are transported to the dosing station 3. 7. During the filling process, the liquid is supplied via the medium line 231 and the cannula-like functional element 230 which is submerged in the container.

[0027] Assembly flow and use of the second example functional module Figure 6 The internal chamber layout, the existing walls and the equipment configuration of the illustrated containment vessel 9 remain essentially unchanged compared to the pair of drawings 1A and 1B, to which reference is therefore made. However, now a second example of a functional module 2 is used, which will be discussed with reference to the series of figures 6 to 8C. Furthermore, here, instead of a transfer device 903 installed in the rear outer wall 900, access to the transfer cell 96 is possible via a simple wall opening 904, or the wall is partially, or at least completely, open along the transfer cell 96.

[0028] The functional module 2 according to the second embodiment is currently in an introduced starting position and, unlike the first embodiment, is not permanently and rigidly attached to the flange connection 20 but is inserted through the wall opening 904 and then docked to the flange connection 20 by accessing it through the open transfer port 260. The functional module 2 has a container 28 sealed to the outside, the sterile interior 29 of which contains the pre-sterilized and fully fitted element support 23 in the introduced starting position. The container 28 has a passage 280 which closes almost automatically in the starting position, through which the fitted element support 23 is moved towards the unwound working position.

[0029] Figures 7A to 7C Based on this series of drawings, the main components of the second example functional module 2 will be described, which include: a) a gas-tight container 28 comprising an outer mounting element 282, a sterile inner chamber 29 and a closable passage 280 surrounded by a window element 281 present on the front side; b) element support 23 with attached functional element 230, front piece 24, and end piece 25 and invisible media conduit 231 (see Figures 8A-8C); c) a lid 285 for closing the container 28 at the rear; and d) an extrusion part 286 configured, for example, as a spindle, and an adjustment mechanism 287, here in the form of a rotating wheel; belongs to.

[0030] Figure 8A In the introduced starting position, the element support 23 with the mounted functional element 230 rests in the container 28 and is therefore not in the dosing station 3. The front piece 24 closes the passage 280 gastight. The medium line 231 connected to the functional element 230 is located with a sufficient length in the inner chamber 29 of the container 28 and leads to the connector 232. As an example of the structure of the medium line 231, the medium line 231 advantageously originating from the connector 232 is distributed to the individual functional elements 230 by branches. However, preferably, a separate medium line 231 for each functional element 230 extends with a sufficient length to the respective connector 232.

[0031] Before the start of production, i.e. while the functional module 2 is still in the installed starting position, it is necessary to simultaneously decontaminate the outer surfaces of the process chamber 93 and the front piece 24 which now hermetically closes the inner chamber 29.

[0032] Figures 8B and 8C By operating the adjustment mechanism 287, the pusher 286 is driven, so that the front piece 24 gradually moves away from the passage 280, and at the same time the element support 23 together with its attachments leaves the container 28 and moves into the processing chamber 93 until it is in the working position, fed out to the dosing station 3. Inside the container 28, the end piece 25 abuts against its front region. As the element support 23 moves out, the previously existing slack length of the media line 231 is extended. During the production process, the liquid to be processed in the dosing station 3 is supplied from the external connector 232 into the media line 231 and further to the functional element 230.

[0033] The use of the functional module 2 of the first embodiment (FIGS. 1A-5) and the second embodiment (FIGS. 6-8C) advantageously involves transporting containers to be filled, for example a batch of four vials, to the dosing station 3 by means of the handling mechanism 12 of the robot 1. The vials are filled, for example with a pharmacological liquid, by means of a functional element 230, which is also located in the dosing station 3 and held by an element support 23. During the filling process, the cannula-shaped functional element 230 is submerged in the open-topped vial. When handling oxygen-sensitive liquids, the filling is carried out under an inert gas blanket, for example nitrogen.
