This disclosure generally relates to cell culture solution formulations. More specifically, this disclosure relates to cell culture solution containers and dispensers.
Cell therapy extends and saves lives. Cancer survival rates, for example, have significantly increased as cell therapy solutions advanced. A critical component in cell therapy solutions is the cell culture media used to grow cells. Traditionally, cell culture media is manufactured as a bulk liquid, packaged in bottles, bags, or large drums ranging from 100 mL to 200 L, and then shipped to cell therapy engineers, bioproduction managers, and scientists. This approach has several drawbacks. The existing containers may be bulky and space-inefficient, increasing shipping costs. Once at the point-of-use, engineers and scientists must store the bulky containers on-site, sometimes requiring large storage areas so that a variety of cell culture medias will be available on-demand. Engineers and scientists may need to add other components to the media and then resterilize because of potential contamination, adding manual steps to the process and causing variability to the cell culture media.

In the following description of embodiments, reference is made to the accompanying drawings which form a part hereof, and in which it is shown by way of illustration specific embodiments which can be practiced. It is to be understood that other embodiments can be used and structural changes can be made without departing from the scope of the disclosed embodiments.
Exemplary containers herein may advantageously decrease shipping costs associated with transporting cell culture solution, may advantageously increase density of a shipment, and may advantageously decrease resources needed to store the cell culture solution before use. In some embodiments, the container contains powdered solution or media and takes a reduced profile for shipment. When needed for use, the container can expand and the powder mixed with water to provide a desired volume of cell culture solution (e.g., cell culture media) on demand. For example, after retrieving the container from storage or a shipment, a user can insert a collapsed container into a dispenser, the dispenser expands the container with the powder, the dispenser adds water, and the dispenser mixes the water and powder to create a desired volume of cell culture solution. Some embodiments of dispensers herein provide sterilization light to sterilize the container prior to mixing. Furthermore, in some embodiments, the disclosed container includes recyclable or reusable material, reducing waste and decreasing environmental footprint.
A person of ordinary skill in the art would recognize that for more general uses such as cell growth media or non-cell growth solution, requirements, steps, and elements may be adjusted accordingly for these uses. For example, those skilled in the art would recognize that requirements, steps, and elements associated with solubility and sterilization will be adjusted accordingly.
As illustrated, container 100 is in an expanded configuration and can be collapsible (e.g., to the configuration illustrated with respect to
In some embodiments herein, a container material can be understood to be rigid when it does not deform during shipping. Additionally, stiffness of rigid ends may cause a middle portion attached to the rigid ends to expand in response to a force pulling the rigid ends apart. In some embodiments, one or both of the rigid ends are opaque to block light from contacting the powdered media or solution inside and degrading any of the components, advantageously reducing additional resterilization steps and reducing variability to the cell culture solution (e.g., cell culture media). For example, existing containers are not opaque and sterilization of containers may adjust the chemical structure of the cell culture solution, thereby introducing variability.
As an exemplary advantage, a reduced profile may advantageously allow for more efficient shipping and reduce agitation of the powder during shipment. Further, rigid first and second ends may provide protection for the content to be stored in the container (e.g., during shipment when the container is in a collapsed configuration) because the content (e.g., cell culture solution powder) may be sensitive to contamination. As described and illustrated herein, the rigidity of the first and second ends allow the container to be expanded in response to an external force separating the ends while the rigid ends serve as an anchor to a dispenser coupled to the container, allowing the container to expand to a larger volume.
In some embodiments, the first end 102 has a thickness 114A, and the second end 104 has a thickness 114B. In some embodiments, the thickness 114A and the thickness 114B are each 10 mm. In some embodiments, the rigid first end and the rigid second end have rectangular cross-sections with radial corners, as illustrated in
Although specific values of quantities (e.g., dimensions, volumes, etc.) are provided, it is understood that in some embodiments, the corresponding values may not be exact. For example, a dimension or a volume may practically be a value functionally equivalent to the exact value. As an example, the value in these embodiments may be different from the exact value, as long as the difference is within a tolerance that does not functionally affect a system's accuracy, operation, and output.
Although the first end 102 and the second end 104 are described as having specific ranges of dimensions, it is understood that other dimensions may exist for the first and second ends without departing from the scope of the disclosure. Furthermore, it is understood that the described dimensions may not necessarily be uniform throughout the first end or the second end.
In some embodiments, the first end 102 and/or the second end 104 is opaque to a sterilization light. In some embodiments, the sterilization light is an ultraviolet light, gamma irradiation, or non-heat based radiation configured to sterilize components (e.g., components of the cell culture solution (e.g., cell culture media) dispenser, such as an air outlet and a water outlet) used in a cell culture solution (e.g., cell culture media) manufacturing process. As an exemplary advantage, by having container ends opaque to a sterilization light, the cell culture solution (e.g., cell culture media) powder container can be protected from the sterilization light (e.g., properties of the cell culture solution powder is prevented from being altered by the sterilization light) while component sterilization is being performed in a collapsed configuration.
In some embodiments, the second end 104 includes a surface 116 on an interior of the container that tapers down (e.g., away from a direction of the first end 102) and towards a center of the second end 104. For example, the rigid second end includes a tapered surface 116 with a minimum thickness at its center, as illustrated. As an exemplary advantage, the tapered surface 116 may allow a stirrer (e.g., a magnetic stir bar) to more efficiently mix a solution associated with the powder in the container by, for example, guiding the movements of the spinning stirrer as the solution is being mixed. The tapered surface 116 may also allow the container to drain more efficiently (e.g., the solution exits the container more efficiently). In some embodiments, a valve is attached to the outlet 110 (described in more detail herein) located on the second end 104; when the solution is being mixed, the valve is closed, preventing the solution from exiting the outlet 110. In some embodiments, when depressed under pressure, the valve is configured to allow fluid to flow. In some embodiments, prior to manufacturing of cell culture media, the valve separates the content from the filter, preventing the content from clogging the filter.
In some embodiments, the first end 102 and the second end 104 include at least one of polyethylene, PLA, and PCL. The material is advantageously included based on environmental needs of a user of the container. In some embodiments, the first end 102, the second end 104, and the middle portion 106 (described in more detail herein) include recyclable material(s). As an exemplary advantage, by using a cell culture solution (e.g., cell culture media) powder container including recyclable material, the environmental footprint of the cell culture solution manufacturing process may be reduced because less plastic may be used or a type of plastics having faster decomposition properties may be used (e.g., compared to PET bottles, compared to bottles that may be treated as biohazard waste) and waste may be minimized. In some examples, the container may be recycled (e.g., the same container may be returned to a manufacturer for resterilization and reuse).
In some embodiments, container 100 includes a stirrer 118 positioned in the region 126. In some embodiments, the stirrer has a length of 10-20 mm and is rectangular or cylindrical. In some embodiments, for bioproduction applications (e.g., the container accommodates a cell culture solution of 2000 L), the stirrer has a length of greater than 20 mm. The cylindrical stir bar may advantageously allow for more efficient mixing of the solution, compared to other stir bar geometries. Further, a cylindrical stir bar can advantageously reduce tearing of the middle portion during sealing, shipment, etc. In some embodiments, the stirrer includes PTFE (e.g., a PTFE based material). In some embodiments, the stirrer 118 includes a magnetic material and is configured to mix a solution associated with the cell culture solution (e.g., cell culture media) powder residing in the container. In some embodiments, the magnetic stir bar rotates (e.g., clockwise or counter-clockwise, relative to the surface 116) in response to an applied magnetic field (e.g., a time-varying magnetic field created by a cell culture dispenser that the container is coupled to) and mix a solution associated with the cell culture solution (e.g., cell culture media) powder residing in the container (e.g., mixing the powder and provided water). In some embodiments, the stir bar may alternate clockwise rotation and anti-clockwise rotation to improve mixing. In some embodiments, a center of the magnetic field is shifted from a center of the container to move a position of the stirrer away from the center of the second end.
In some embodiments, container 100 includes a QR code 120 attached to the first end 102 and associated with a content to be stored in the container. In some embodiments, the QR code 120 is attached to an access port cover 124, a hood, or a cap covering an opening (e.g., an access port) of the first end 102. Although the QR code 120 is described as being attached to the first end 102 or the access port cover 124, it is understood that the QR code 120 may be attached to second end 104, or the middle portion 106). For example, the QR code 120 may identify the cell culture solution (e.g., cell culture media) powder to be stored in the container and an associated formula for preparing a specific cell culture solution (e.g., cell culture media) formulation. A cell culture solution (e.g., cell culture media) dispenser or system may use the QR code (e.g., by using a scanner, by using a camera) to quickly identify the content of the container and the formula associated with the content and be configured (e.g., provide a suitable amount of water, provide a suitable amount of air, determine stirring time, determine a pH of the solution) to manufacture the cell culture solution (e.g., cell culture media) based on the content. In some embodiments, the dispenser is configured to communicate with a manufacturing facility to provide data on the dispenser's use. Although a QR code is used to describe the identification of a content to be stored in the container, it is understood that other elements (e.g., a bar code, a pattern, radio frequency identification, etc.) may identify the content to be stored without departing from the scope of the disclosure.
In some embodiments, the first end 102 and the second end 104 include guides 122 configured to couple the ends to a dispenser with complimentary ports for the inlet and the outlet (as depicted in
In some embodiments, container 100 includes an opening (e.g., an access port) located on the rigid first end. In some embodiments, the opening is a sealable opening located on the rigid first end configured to provide access to the region 126 for the addition of powder and to then seal and/or vacuum the region 126 after the powder is added. In some embodiments, the sealable opening is occluded by an access port cover 124, a sterile hood, or a cap including a material similar to the rigid first end.
In some embodiments, the middle portion 106 is deformable (e.g., to the configuration illustrated with respect to container 150; the middle portion is flexible, as described herein; the middle portion is foldable, as described herein). In some embodiments, the container includes cell culture solution (e.g., cell culture media) powder in the region 126.
In some embodiments, in the expanded configuration, the middle portion 106 of container 100 is expanded. In some embodiments, in the expanded configuration, a max volume of container 100 (e.g., when middle portion 106 is expanded) accommodates a specific volume of solution, where the volume is in the range of 500 mL to 2000 L. In some embodiments, in the expanded configuration, the first and second ends are separated by a distance 112. For example, the distance 112 is 120 mm when a volume of the container in an expanded configuration accommodates a 500 mL solution. As another example, the distance 112 is 300 mm when a volume of the container in an expanded configuration accommodates a 5 L solution. As another example, the distance 112 is 1.2 m when a volume of the container in an expanded configuration accommodates a 500 L solution. As another example, the distance 112 is 1.9 m when a volume of the container is in an expanded configuration for mixing a 2000 L solution.
By designing the middle portion 106 to have a distance 112, mixing and container size may be advantageously optimized. For example, for a container in an expanded configuration for mixing a 500 mL solution, the distance 112 is 120 mm (e.g., a width of the middle portion is 85 mm, and a length of the middle portion is 85 mm). The total volume of the exemplary container in the expanded configuration is 867 mL, allowing a level of the 500 mL solution to rise while mixing (e.g., the solution becomes vortex shaped such that a top surface of a solution rises higher, compared to a top surface of a still 500 mL solution) and allowing the middle portion to fit (e.g., the middle portion did not become too large, such that it would not fit within the first and second ends) within the first and second ends while the container is in a collapsed configuration.
The volume of the container in the expanded configuration may differ based on the application. For example, a container having an expanded configuration volume for mixing a 500 mL or a 5 L solution may be used in a laboratory environment to produce a smaller volume of cell culture solution (e.g., cell culture media), and a container having an expanded volume for mixing a 500 L or 2000 L solution may be used in a factory environment (e.g., bioprocessing) to produce a larger volume of cell culture solution (e.g., cell culture media).
In some embodiments, in the expanded configuration, the container has a height-to-width ratio greater than one half (e.g., the height of the container is greater than a width of the container). For example, the ratio is 1.2. As an exemplary advantage, a container having a height-to-width ratio greater than one half facilitates solubilization of content in the container (e.g., a distance from a stirrer to the content being mixed, across a plane of the second end, is reduced). For example, using a 15 mm stirrer and rotating the stirrer at 2000 RPM (e.g., to mix the container contents), content in a container having a height-to-width ratio greater than one half (e.g., 1.2) has a greater solubility (e.g., measured based on conductivity of the content). That is, the content converges toward an optimal solubility faster (e.g., around 400 seconds), compared to a container having a height-to-width ratio less than one half (e.g., around 800 seconds).
In some embodiments, a volume of the container is greater in the expanded configuration than the collapsed configuration. In some embodiments, a distance between the first end and second end is greater in the expanded configuration than the collapsed configuration. For example, in the expanded configuration, a distance between the first end and the second end is 120 mm, and a volume of the container is 867 mL. In the collapsed configuration, the distance between the first end and the second end is less than 120 mm (e.g., 0 mm) and the volume of the container is less than 500 mL (e.g., 20 mL).
In some embodiments, the middle portion 106 is flexible. For example, material of middle portion 106 stretches beyond its resting shape in response to a pulling force. In some embodiments, the middle portion 106 is not flexible. For example, material of the middle portion 106 does not stretch in response to a pulling force (for example, the middle portion is an accordion shape that allows for elongation of the middle portion when pulled, but the material does not stretch). In some embodiments, the middle portion 106 is deformable in response to an external force to alter the configuration of the container and mixing regime associated with content of the container.
In some embodiments, when the container is in the expanded configuration, the middle portion 106 includes a rectangular cross-section (as illustrated). For example, for a container having a volume for mixing a 500 mL solution at an expanded configuration, the rectangular middle portion has a width of 85 mm and length of 85 mm. As another example, for a container having a volume for mixing a 5 L solution at an expanded configuration, the rectangular middle portion has a width of 170 mm and length of 170 mm. In some embodiments, when the container is in the expanded configuration, the middle portion includes a circular cross-section (not shown). For example, the diameter of the circular cross-section is 73 mm.
Although the dimensions of container 100 is described with respect to a distance between two points, it is understood that the shape of the middle portion may not be perfectly cubic (e.g., an edge of the middle portion is not straight).
In some embodiments, middle portion 106 is a polyethylene bag, a polypropylene bag, or other sterilizable plastic bag attached to the first end 102 and the second end 104. In some embodiments, the middle portion 106 is a multi-layer bag including a polyethylene layer for heat sealing and nylon for reducing gas exchange. In some embodiments, a base of the bag is tucked into or clipped onto the second end 104. For example, the second end 104 includes features (e.g., the second end 104 includes a first piece and a second piece that hold the base of the bag together) that allow the base of the bag to snap into the second end 104. In some embodiments, the container includes a first seal (not shown) between the rigid first end and the middle portion, and the container includes a second seal (not shown) between the rigid second end and the middle portion. The seal may advantageously protect the contents of the container (e.g., protect the powder from contamination, protect the solution from contamination during mixing).
In some embodiments, the cell culture solution (e.g., cell culture media) powder is stored in a powder sachet (not shown). For example, the middle portion 106 is configured to store the powder sachet containing the powder. In some embodiments, the powder sachet includes a 20-50 μm mesh. In some embodiments, when the container is in an expanded configuration, the powder sachet is configured to be displaced from the rigid second end (e.g., attached to the rigid first end, attached to the middle portion).
In some embodiments, the container includes a barrier in the middle portion separating the powder from at least one of the first end and the second end. In some embodiments, the barrier is at a height from the rigid second end when the container is in the expanded configuration. In some embodiments, the barrier is located at a height selected to allow a predetermined volume of water to be added to the container before dissolution begins.
The powder sachet and/or the barrier may advantageously keep a stirrer in the middle portion away from the cell culture solution (e.g., cell culture media) powder prior to mixing or before enough water is added to the container during mixing. Before mixing or when sufficient water is added to the container during mixing, the powder sachet and/or the barrier may dissolve, dropping the powder onto the rigid second end and allowing mixing to begin.
In some embodiments, container 100 includes inlets 108A and 108B and an outlet 110. In some embodiments, an inlet 108A or 108B is located on the first end 102, and the outlet 110 is located on the second end 104. In some embodiments, the inlets 108A and 108B and outlet 110 are fluidly coupled to the region 126 of the container. In some embodiments, two elements are fluidly coupled if a fluid (e.g., water, air, a solution) can flow between the elements. For example, a fluid can flow between the inlets 108 and the region 126 within the container (e.g., water or air can follow from an inlet to the region 126), and a fluid can flow between the region 126 within the container and outlet 110 (e.g., a solution can flow from the region 126 to the outlet). In some embodiments, the outlet 110 has a height of 16 mm. In some embodiments, cell culture solution (e.g., cell culture media) powder and/or a stirrer are loaded into the container through one of the inlets or the outlet. In some examples, the cell culture solution (e.g., cell culture media) powder and/or a stirrer are loaded into the middle portion prior to assembling the container. In some embodiments, the content of the container is weighed and blended prior to being loaded into the container.
In some embodiments, the outlet 110 is located such that when a filter is coupled to the outlet, the coupled filter does not physically impede a magnetic field generator from aligning with the second end of the container while the magnetic field generator drives a stirrer during mixing. For example, as described with respect to
In some embodiments, a material occludes the outlet 110. In some embodiments, the material occluding the outlet is different than the material of the surface 116. In some embodiments, the material occluding the outlet comprises low-density polyethylene. In some embodiments, the material occluding the outlet is configured to tear or break open in response to an applied pressure (e.g., 5-10 psi) above a pressure threshold (e.g., 2-5 psi). In some embodiments, the material occluding the outlet has an area of 1 cm2. The material occluding the outlet may advantageously keep the content (e.g., cell culture solution powder) of the container 100 sterile until the content is being used for manufacturing a solution. During manufacturing, when a solution is ready to exit the container, a pressure above the pressure threshold is applied in the container (e.g., by using pumping air, by collapsing the container 100), causing the material to tear or break and allowing the solution to exit the container 100 through the outlet 110. In some embodiments, prior to manufacturing of cell culture media, the material occluding the outlet separates the content from the filter, preventing the content from clogging the filter.
In some embodiments, the container 100 has a larger volume (e.g., 500 L, 2000 L) and is used with a bioreactor. The cell culture solution (e.g., cell culture media) powder for containers having a larger volume may be loaded from bags (e.g., 20 L) and drums into the container through an opening of the container (e.g., an opening on the first end of the container).
In some embodiments, the inlets 108A and 108B are located on the first end 102. In some embodiments, the inlets 108A and 108B are located on a same side of the first end 102. In some embodiments, inlets 108A and 108B are parallel so that they connect to the corresponding attachments on a dispenser while container 100 is inserted into the dispenser. In some embodiments, one of the inlets 108A and 108B is an air inlet, and the other is a water inlet. In some embodiments, the container includes one inlet, and the inlet is an air and/or water inlet. In some embodiments, the air inlet is configured to couple to an air outlet of a cell culture solution (e.g., cell culture media) dispenser. In some embodiments, a HEPA filter is placed at the air inlet for sterilization by controller airflow. In some embodiments, the water inlet is configured to couple to a water outlet of a cell culture solution (e.g., cell culture media) dispenser. In some embodiments, the water inlet is configured to transport United States Pharmacopoeia (USP) grade water or highly purified water suitable for manufacturing cell culture solution (e.g., cell culture media) from a cell culture solution (e.g., cell culture media) dispenser to a middle portion of the container.
As an exemplary advantage, a dispenser (e.g., a cell culture solution (e.g., cell culture media) dispenser) configured to couple to the inlets and the outlet of the container may better align to the container because the fixed positioning of the inlets and the outlet reduces complexity of alignment between the container and the dispenser, even for different kinds of media powders.
In some embodiments, the container 100 includes an adapter (not shown) attached to an inlet 108A or 108B. In some embodiments, the adapter includes at least one of a Luer Lock adapter and a PVT adapter. As an exemplary advantage, the adapter allows for simple, but reliable interface between the container and a cell culture solution (e.g., cell culture media) dispenser.
In some embodiments, container 100 includes a filter (not shown). In some embodiments, the filter is a sterile filter. In some embodiments, the filter is a filter cartridge. During mixing, the filter may be used to filter undesirable by-product in the solution as the solution exits the container (e.g., through the outlet 110). In some embodiments, the filter has a pore size of 0.22 μm to 1 μm. In some embodiments, the filter is attached to the outlet 110 separately. In some embodiments, a filter is integrated with the outlet 110 (e.g., the filter is part of the container assembly, the filter is part of a base of the container, the filter is pre-attached to the outlet prior to manufacturing cell culture media, the filter is part of the outlet), advantageously reducing a need to separately attach the filter to the outlet.
In some embodiments, the filter is provided by a dispenser (e.g., dispenser 300, a cell culture solution (e.g., cell culture media) dispenser). For example, the filter is stored in the dispenser, and in response to an input (e.g., a mechanical input or electrical input from a user, a determination by the dispenser), the dispenser provides the filter. In some embodiments, the filter is installed onto the outlet 110 of the container (e.g., using the spring mechanism described). In some embodiments, the filter is installed onto the outlet 110 of the container manually. In some embodiments, the dispenser automatically installs the filter onto the container (e.g., before the solution exits the container, when the solution is ready to be transferred to another container for storage).
As an exemplary advantage, by providing the filter separately and installing the filter onto the container at a point of use, the size of the container may be reduced (e.g., to increase shipping efficiency), and the content of the container may be less likely damaged or contaminated. Furthermore, different types and sizes of filters may be provided, allowing a more suitable filter to be chosen for each use (e.g., including a suitable filter with the container may not be cost or size efficient).
In some embodiments, the outlet 110 is configured to attach to an evacuation tube (not shown). To optimize shipping volume, the evacuation tube may be attached after shipping and before mixing. In some embodiments, during or after mixing, the evacuation tube guides the solution to a second container for storing the solution. In some embodiments, the evacuation tube includes a Luer Lock fitting, sterilizable plastic tube, and a sealing nozzle. In some embodiments, the evacuation tube includes a filter used to filter undesirable by-product in the solution as the solution exits the container. In some embodiments, the evacuation tube is bendable or flexible. The bendable or flexible evacuation tube may allow the tube to be more efficiently shipped and allow the tube to be more easily guided to a second container for storing the solution during or after mixing.
In some embodiments, the outlet 110 is mounted on a spring mechanism. This allows the outlet to automatically close and open in response to the filter (e.g., provided by dispenser 300, provided by a cell culture solution (e.g., cell culture media) dispenser) being inserted or in response to an another force associated with dispensing the mixed solution.
In some embodiments, the container includes a pH sensor (not shown) sensing a pH level associated with a content to be stored in the container. A pH level of the media powder may be advantageously monitored during its lifetime (e.g., from being loaded into the container, to being shipped, to being mixed) to ensure product quality. In some embodiments, the media powder is pre-granulated by spray addition of a pH correcting agent (e.g., an acid, a base) at a determined quantity. For example, the pH correcting agent is added to the media powder on a fluid bed to facilitate drying and incorporation of the correcting agent with the powder. In some embodiments, the container includes a dissolution sensor (not shown) configured to determine a level of dissolution associated with the content of the container (e.g., if the solution is adequately mixed).
Although container 100 is described with respect to the elements described in
As an exemplary advantage, from shipment to formulation, the content (e.g., cell culture solution (e.g., cell culture media) powder) can reside in a same collapsible and expandable container and may not need to be transferred from one container to another, reducing risks of contaminating the content. As another exemplary advantage, the collapsibility of the container allows contents of the container to be easily expelled from the container (e.g., squeezing the contents out after usage) to allow the container to be more recyclable or be more ready for resterilization and be reused.
In some embodiments, the container changes from the expanded configuration the collapsed configuration or from the collapsed configuration to the expanded configuration using a tool or a machine. For example, when the container is in an expanded configuration (e.g., when content of the container is being loaded), the first and second ends of the container are slid into or secured to slots of the tool or the machine. The slots of the machines are apart from each other at a distance of a height of the container in the expanded configuration. The tool or the machine can change the container from the expanded configuration to the collapsed configuration (e.g., after the container is ready to be packaged, shipped, or stored) by decreasing the distance between the slots (e.g., a slot is controlled by a descending mechanism, reducing the distance between the slots).
In some embodiments, the container 150 includes similar elements described with respect to
In some embodiments, in the collapsed configuration, the middle portion 156 of the container 150 is collapsed. In some embodiments, in the collapsed configuration, the first and second ends are in contact (e.g., when the container in the collapsed configuration, a distance between the first and second end is 0 mm). In some embodiments, the thickness of the container in the collapsed configuration is 20 mm. In some embodiments, a shipping thickness of the container (e.g, the thickness of the container and the height of the outlet) in the collapsed configuration is 36 mm.
In some embodiments, the container 150 is configured to stack with another container. In some embodiments, a surface of the first end 152 is configured to interface with a surface of the second end 154. In some embodiments, a top surface of a first end 102 of a first container is configured to interface with a bottom surface of a second end 154 of a second container. In some embodiments, the top surface of the rigid first end and the bottom surface of the rigid second end is flat, allowing adjacent containers to be stacked. In some embodiments, the top surface of the rigid first end and the bottom surface of the rigid second end includes features (e.g., groves, guides, notches, inserts) that allow the two surfaces to interface securely, allowing a plurality of containers to be efficiently and securely packed for shipping and storage (e.g., compared to more bulky containers that are not space efficient). Therefore, using the disclosed containers to store cell media culture powder may advantageously decrease shipping costs associated with transporting the powder, increase density of a shipment, and decrease resources (e.g., storage space) needed to store the powder before use. In some embodiments, during shipment or storage, an outlet 160 of the container 150 is placed in a protective packaging to prevent the outlet (and its interface to a filter) from being damaged.
In some embodiments, to prevent contamination and to maximize the shelf life of the container content, the middle portion 156 of the container 150 is vacuum-sealed. For example, the first end includes an opening (e.g., an access port) and the opening is configured to allow the vacuum to be created (e.g., allow a tube to remove air from the region 126 of the container). In some embodiments, after air is removed from the middle portion, the middle portion is sealed (e.g., the opening allows access to a portion of the bag to be sealed) and the opening is covered by an access port cover 174, a hood, or a cap, securing the vacuum in the middle portion.
In some embodiments, a barrier is used to prevent contamination and to elongate shelf life of the container content during shipment and storage or separate between different contents in the container. In some embodiments, the barrier is formed by the middle portion 156 when the container is in the collapsed configuration. For example, the middle portion 156 includes a foldable bag. When the container is in the collapsed configuration, the bag is folded such that the folds of the bag serves as sealed barriers (e.g., the content is separated from at least one of the first end and the second end by the barrier) for the content in the barrier. In some embodiments, the sealed barriers in the middle portion 156 are configured to maintain the vacuum within the middle portion 156 when the container is in the collapsed configuration.
In some embodiments, the barrier of the middle portion 156 is created when the container changes from the expanded configuration to the collapsed configuration (e.g., when the container content is being loaded, after the content is loaded, after a first content is loaded and before a second content is loaded). In some embodiments, as the container changes (e.g., during a method of manufacturing a cell culture container, such as manufacturing methods described herein) from the expanded configuration to the collapsed configuration, a tool (e.g., an off-center slit that the middle portion passes through) causes the middle portion to fold in a specific manner, such that the fold of the middle portion (e.g., the fold of a bag) creates the barrier.
In some embodiments, the barrier of the middle portion 156 separates a first content and a second content in the container while the container is in the collapsed configuration. When the container changes from the collapsed configuration to an expanded configuration (e.g., before mixing of the content), the barrier opens and allows the first and second content to be together in the middle portion.
Although the container 150 is described with respect to the elements described in
In some embodiments, the first end 152 and the second end 154 include guides 172 configured to couple the ends to a dispenser configured to couple to the inlet and the outlet. In some embodiments, the guides 172 are located on opposing ends of the first end 102 and on opposing ends of the second end 154, as illustrated. Advantageously, the guides 172 may be configured to allow the container to slide into a dispenser (e.g., a cell culture solution (e.g., cell culture media) dispenser coupling to the container to manufacture cell culture solution (e.g., cell culture media)) configured to couple to the container and the container to be securely installed into the dispenser.
In some embodiments, prior to manufacturing cell culture solution (e.g., cell culture media), the guides 172 slide into slots of a cell culture solution (e.g., cell culture media) dispenser. In some embodiments, the container is in a collapsed configuration when the container is installed (e.g., slide into slots of the cell culture solution (e.g., cell culture media) dispenser like a cassette tape) into the cell culture solution (e.g., cell culture media) dispenser. In some embodiments, after the container is securely installed into the dispenser, the guides 172 keep the rigid first and second ends at a fixed position relative to the slots that guides 172 are interfacing with. In some embodiments, with the guides 172 keeping the rigid first and second ends at a fixed position relative to the slots, the cell culture solution (e.g., cell culture media) dispenser causes the slots to part vertically, such that the middle portion 156 expands. As such, the containers 100 and 150 may advantageously allow the content to be efficiently shipped and adaptable to a machine for media formulation.
In some embodiments, the first end 152 and the second end 154 are configured to lock the container 150 in the collapsed configuration when the first end 102 is rotated at a first angle from the second end 154 relative to an orientation of the first end 102 and the second end 154 when the container is in the expanded configuration (e.g., twisted like a cap). In some embodiments, turning the first end 102 clockwise relative to the second end 154 locks the container 150 in the collapsed configuration, and turning the first end 102 counter-clockwise relative to the second end 154 unlocks the container 150 from the collapsed configuration (e.g., allowing the container to expand).
In some embodiments, the first end 152 includes a notch configured to mate with an opening of the second end 154 and lock the container in the collapsed configuration. In some embodiments, the first end 152 includes notches that can interface (e.g., mate, attach, couple) with corresponding openings on the second end 154 to lock the container in the collapse configuration. A user may pull the first end 152 and the second end 154 away from each other to detach the two rigid ends away from each other.
By allowing the first and second ends to lock when the container is in a collapsed configuration, the content of the container may be advantageously secure during shipment and/or storage. In some embodiments, the middle portion of the container is in a vacuum when the container is in the collapsed configuration. The vacuum in the middle portion may be advantageously maintained by allowing the container to lock.
In some embodiments, the filtration system 202 is an ultra-pure water (UPW) filtration system. For example, the UPW filtration system includes a water inlet configured to receive water (e.g., UPW water, USP water, water from an external source). In some embodiments, the water passes through a UPW filter of the filtration system and into a water reservoir of the filtration system 202. In some embodiments, the water circulates between the filter and the reservoir to maintain or increase the purity of the water. In some embodiments, the water in the filtration system is provided (e.g., pumped) to the first handling system 204.
In some embodiments, the first handling system 204 includes a container chamber, an inlet, container handling mechanism, and a mixing system. In some embodiments, the container chamber is an enclosure for insertion, expansion, and/or collapsing of a container (e.g., container 100, container 150, container 308, container 608). In some embodiments, the container chamber is sterilized (e.g., using a sterilization light). For example, prior to mixing container content, the container chamber is sterilized (e.g., by the dispenser 200, by a device different from the dispenser 200). In some embodiments, the dispenser 200 comprises a heating chamber to heat water and air to sterilize the dispenser's piping. In some embodiments, the dispenser 200 comprises an ozone generator for removing contaminants in the chamber (e.g., to purify water, to purify air).
In some embodiments, the inlet of the first handling system 204 is an inlet configured to couple to an inlet of a container (e.g., inlet 108A, inlet 108B, inlet 158A, inlet 158B). In some embodiments, the inlet provides water (e.g., from the filtration system 202) and/or air for the container. In some embodiments, the inlet of the first handling system 204 advantageously aligns with an inlet of a container when the container is inserted, allowing installation of the container into the dispenser to be more efficient. In some embodiments, the inlet is cleaned or sterilized (e.g., using a sterilization light). For example, prior to mixing container content, the inlet is cleaned or sterilized (e.g., by the dispenser 200, by a device different from the dispenser 200).
In some embodiments, the container handling mechanism includes an insertion mechanism (e.g., slots 304) configured to accept a container as the container (e.g., container 100, container 150, container 308, container 608) is being inserted (e.g., the slots are configured to match the guides (e.g., guides 122, guides 152) of the container) and secure the container after the insertion of the container. In some embodiments, the insertion mechanism includes two portions (e.g., slots 304A and 304B) that are configured to move apart. Because the container is secured to the insertion mechanism, when the container is in a collapsed configuration, as the insertion mechanism moves apart, the insertion mechanism causes the container to expand. In some embodiments, the insertion mechanism includes two portions (e.g., slots 304A and 304B) that are configured to move closer together. Because the container is secured to the insertion mechanism, when the container is in an expanded configuration, as the insertion mechanism moves closer together, the insertion mechanism causes the container to collapse.
In some embodiments, the mixing system includes hardware for driving a stirrer used for mixing the contents of a container. For example, the mixing system includes a magnetic field generator for driving a magnetic stirrer for mixing. As an example, the magnetic field generator generates a time-varying magnetic field to drive or guide the stirrer to rotate as intended to mix the contents of the container.
In some embodiments, the first handling system 204 provides a filter (e.g., a filter cartridge). For example, the filter is provided from the dispenser 200, and is loaded on a rail aligned with the container. The filter is coupled to an outlet of the container and the content of the container (e.g., cell culture solution (e.g., cell culture media)) passes through the filter before dispensing the content into a second container. In some embodiments, after the content is dispensed into the second container, the first handling system 204 disposes the used filter. In some embodiments, a filter is integrated with the outlet, advantageously reducing a need to separately attach the filter to the outlet and/or dispose the filter. As such, the first handling system 204 does not separate attach the filter to the outlet and/or separately dispose the filter.
In some embodiments, after the content is dispensed into the second container, the first handling system 204 disposes the used container. In some embodiments, the used container is ejected and is reused, as described herein.
In some embodiments, the second handling system 206 includes a second container chamber and a second container access mechanism. In some embodiments, the second container chamber is an enclosure for insertion of a second container (e.g., container 306, a media bottle) and dispensing of content from a first container (e.g., container 100, container 150, container 308, container 608) to the second container. In some embodiments, the container chamber is sterilized (e.g., using a sterilization light). For example, prior to dispensing the first container content, the second container chamber is sterilized (e.g., by the dispenser 200, by a device different from the dispenser 200).
In some embodiments, the second container access mechanism includes a motor driven element that is configured to unscrew a cap of the second container (e.g., in accordance with a determination that the solution in the container is ready for dispensing). In some embodiments, while the cap of the second container 306 is being removed, the second container is being lowered (e.g., by the second container access mechanism) to separate the cap from the second container. In some embodiments, the second container access mechanism includes a motor driven element that is configured to screw a cap of the second container (e.g., in accordance with a determination that the solution in the container has been completely transferred). In some embodiments, the motor driven element screwing and unscrewing the cap is a same element. In some embodiments, while the cap of the second container is installed, the second container is raised (e.g., by the second container access mechanism) to mate the cap with the second container. In some embodiments, an interface between the second container access mechanism and the cap of the second container is adjustable (e.g., the diameter of the interface is adjustable) to accommodate different container sizes.
In some embodiments, the dispenser 200 includes a user interface, hardware, and software for operating the dispenser. In some embodiments, the dispenser 200 includes a scanner (e.g., a QR code scanner) for scanning information on a container (e.g., scanning QR code 120, scanning QR code 170). Advantageously, instructions for operating the dispenser 200 may be updated through software and firmware updates.
In some embodiments, the GUI 302 is displayed on a touch screen and is configured to receive input for cell culture solution (e.g., cell culture media) manufacturing. In some embodiments, prior to mixing, the GUI 302 displays a prompt for a user to install or insert a container (e.g., container 100, container 150) including media powder used for manufacturing cell culture solution (e.g., cell culture media). In some embodiments, the GUI 302 includes user-configurable options that defines aspects of the cell culture solution (e.g., cell culture media) manufacturing process.
In some embodiments, the slots 304 are configured to accept a container (e.g., container 100, container 150) including media powder used for manufacturing cell culture solution (e.g., cell culture media). In some embodiments, the guides (e.g., guides 122, guides 172) of the container are configured to interface with the slots such that the container can be slid into the slots using the guides. In some embodiments, when the container is completely slid into the slots, the slots 304 secures the container, preventing the container from moving (e.g., during mixing). In some embodiments, the dispenser 300 includes air and water outlets (not labeled) that can be coupled to inlets (e.g., inlets 108A and 108B, inlets 158A and 158B) when the container is sliding into the slots or otherwise before the content of the container is mixed. In some embodiments, the air and water outlets align with inlets (e.g., inlets 108A and 108B or 158A and 158B) such that sliding the container into the slots would cause the outlets of the dispenser to couple with the inlets of the container without additional adjustment to align the container with the dispenser. In some embodiments, the air and water outlets of the dispenser 300 provide air and water (e.g., USP grade water, water suitable for cell culture solution (e.g., cell culture media) manufacturing).
Although the slots 304 of the dispenser 300 are described to guide the container 308 during insertion and keep the container 308 secure during expansion, it is understood that insertion of the container may be guided or the container may be kept secured during expansion using other components. For example, a component with different mechanical features (e.g., allowing the container to snap to the dispenser), with electromagnetic features, or with adhesive properties may be used along with or instead of the slots 304.
In some embodiments, the second container 306 stores a solution (e.g., a media bottle) associated with the content of the installed or inserted container 308 (e.g., a solution produced by the dispenser 300). In some embodiments, the solution exits an outlet (e.g., outlet 110, outlet 160) of a container before being transferred to the second container 306.
In some embodiments, upon installation or insertion of the container 308, the GUI 302 is updated to prompt a user to begin the cell culture manufacturing process. In some embodiments, the GUI 302 is updated to display a selectable option to begin the cell culture manufacturing process.
In some embodiments, the content of the container 308 is identified by the dispenser 300, and the cell culture manufacturing process is performed based on the identification of the content in the container 308. In some embodiments, the content is identified using a QR code (e.g., QR code 120, QR code 170) on the container 308. In some embodiments, the dispenser 300 includes a scanner or a camera configured to scan identifying information (e.g., QR code, barcode, patterned code, radio frequency identification) on the container to identify the container content. In some embodiments, the camera or a second camera of the dispenser 300 is configured to monitor the chamber of the dispenser; images or video from the camera may be viewed on the display of the dispenser 300 or on a display of a second device in communication with the dispenser 300. For example, a sterility of the chamber is monitored based on the camera, and based on the monitoring, in accordance with a determination that the chamber requires sterilization, the dispenser 300 performs a sterilization operation. As another example, the cell culture solution manufacturing is monitored using the camera, and based on the monitoring, the dispenser 300 adjusts a manufacturing parameter (e.g., stirrer speed, mixing time). In some embodiments, a second device (e.g., a mobile device) is used to scan the identifying information (e.g., the second device uses an application to scan the identify information and communicate the identifying information with the dispenser 300). In some embodiments, the GUI 302 presents information about the content in the container 308 identified by the dispenser 300. In some embodiments, the GUI 302 presents selectable or configurable options for a user to input or update information regarding the identified content.
In some embodiments, when dispenser 300 expands the container 308, the dispenser causes the slots 304A and slots 304B to move away from each other in a direction parallel to a direction of the intended expansion (e.g., vertically). Because the rigid ends are locked at fixed positions to the respective slots, the middle portion (e.g., middle portion 106, middle portion 156) of the container 308 is caused to be expanded (e.g., toward an expanded configuration of the container, such as the configuration illustrated in
In some embodiments, when the container 308 is being expanded by the dispenser 300, the GUI 302 presents a progress of the cell culture solution (e.g., cell culture media) manufacturing process. In some embodiments, the current step, the container content, the solution being manufactured, and a progress is shown on the GUI 302.
In some embodiments, compared to
In some embodiments, when the desired volume of the container 308 is reached and the slots 304A and slots 304B stop expanding the container 308, the dispenser 300 aligns and couples the air and water outlets of the dispenser 300 and the inlets 108A and 108B or 158A or 158B.
In some embodiments, after the air and water outlets of the dispenser 300 and the inlets of the container 308 are aligned and coupled, mixing of the solution begins. In some embodiments, the air and water outlets of the dispenser 300 begin providing a suitable amount of air and water (e.g., USP grade water, water suitable for cell culture solution (e.g., cell culture media) manufacturing) into the container 308. In some embodiments, additionally, the dispenser 300 generates a magnetic field near the rigid second end (e.g., the rigid end coupled to slots 304B) of the container 308 to cause a stirrer included in the container to start rotating (e.g., clockwise relative to a surface of the rigid second end, counter-clockwise relative to a surface of the rigid second end).
In some embodiments, the content of the container is mixed using the stirrer for a pre-determined amount of time. In some embodiments, the amount of time is determined based on the cell culture solution (e.g., cell culture media) being manufactured. In some embodiments, identifying information (e.g., QR code, barcode, patterned code, radio frequency identification) on the container 308 includes information relating to mixing time, and the information relating to mixing time is input to the dispenser 300 when the content of the container is identified.
In some embodiments, when the solution is determined to be complete (e.g., the pre-determined amount of time has lapsed, the solubility of the liquid is determined to be achieved through measurement), the solution exits from an outlet (e.g., outlet 110, outlet 160) of the container 308 into the second container 306. In some embodiments, the solution passes through a filter, and the filter is included in the container 308. In some embodiments, prior to the solution exiting, the dispenser 300 opens a covering (e.g., a cap) of the second container 306 to allow the solution to be transferred from the container 308 to the second container 306. For example, the dispenser 300 includes a motor driven element that is configured to unscrew a cap of the second container 306 in accordance with a determination that the solution in the container 308 is ready for dispensing. In some embodiments, while the cap of the second container 306 is being removed, the second container is being lowered to separate the cap from the second container 306.
In some embodiments, after the solution is moved to the second container 306, the solution is suitable for the growth of cells or transferred to facilitate the growth of cells. Although the content of the container is described with respect to cell growth (e.g., cell culture solution (e.g., cell culture media)), it is understood that the description of the container content is not limited to cell growth. For example, cell growth may include tissue growth. As another example, cell culture may include tissue culture.
In some embodiments, the dispenser 300 performs the reverse steps (e.g., after a solution is created and is ready for dispensing in the second container 306). For example, the dispenser 300 includes a motor driven element that is configured to screw a cap of the second container 306 in accordance with a determination that the solution in the container 308 has been completely transferred. In some embodiments, while the cap of the second container 306 is being installed, the second container is being raised to mate the cap with the second container 306. In some embodiments, an interface between the dispenser 300 and the cap of the second container 306 is adjustable (e.g., the diameter of the interface is adjustable) to accommodate different container sizes.
In some embodiments, the dispenser 300 includes an enclosure or chamber (not shown). As an exemplary advantage, the enclosure allows for the sterile environment during preparation of the solution or when the solution is transferred from the cell culture solution (e.g., cell culture media) container. In some embodiments, the dispenser 300 comprises a heating chamber to heat water and air to sterilize the dispenser's piping. In some embodiments, the dispenser 300 comprises an ozone generator for removing contaminants in the chamber (e.g., to purify water, to purify air).
In some embodiments, when the container 308 is expanded to the expanded configuration and the solution begins to mix, the GUI 302 presents a progress of the cell culture solution (e.g., cell culture media) manufacturing process. In some embodiments, the current step, the container content, the solution being manufactured, and a progress is presented on the GUI 302.
In some embodiments, the container 308 is used in a bioreactor. Instead of a second container 306, as illustrated, the solution created from the contents of the container 308 is transferred to a bioprocessing vessel (e.g., the bioreactor provides a connection that allows fluid to flow from the container 306 to the bioprocessing vessel).
In some embodiments, the method 400 includes receiving a first container in a collapsed configuration into a dispenser (step 402). For example, the dispenser 300 receives the container 308 inserted into the dispenser, as described with respect to
In some embodiments, the method 400 includes sterilizing the dispenser. For example, prior to insertion of the container 308 or prior to mixing, components (e.g., a chamber where the first container 308 is inserted, a chamber where the second container 306 is placed, an inlet of the dispenser 300) of the dispenser 300 are sterilized (e.g., by the dispenser 300, by a device different from the dispenser 300). In some embodiments, the components are sterilized using a sterilization light (e.g., a UV light). As another example, after a cell culture solution is created and retrieved, the dispenser performs the sterilization. In some embodiments, the dispenser comprises a heating chamber to heat water and air to sterilize the dispenser's piping. In some embodiments, the dispenser comprises an ozone generator for removing contaminants in the chamber (e.g., to purify water, to purify air).
In some embodiments, the method 400 includes expanding the first container to an expanded configuration (step 404). For example, the dispenser 300 expands the container 308, as described with respect to
In some embodiments, the method 400 includes receiving an input. In some embodiments, the input is a selection on a GUI of the dispenser, and the first container is expanded in response to receiving the input. For example, a user provides an input by making a selection on the GUI 302, and in response to the selection, the dispenser 300 expands the container 308 and mixing begins. In some embodiments, the input is a QR code scan of a QR code of the first container, and the first container is expanded in response to receiving the input. For example, a QR code (e.g., QR code 120, QR code 170) of the container 308 is scanned (e.g., by the dispenser 300, by a different than the device 300), and in response to the scanning, the dispenser 300 expands the container 308 and mixing begins. As another example, as described with respect to
In some embodiments, the method 400 includes while the first container is expanding or the first container is in the expanded configuration, injecting water into the first container (step 406). For example, while the dispenser 300 expands the container 308 or when the container 308 is in the expanded configuration, the dispenser 300 injects water (e.g., USP grade water) in the container 308, as described with respect to
In some embodiments, the method 400 includes applying a baffle to the first container. In some embodiments, the baffle is applied to the first container while the first container is expanding or the first container is in the expanded configuration. For example, as described with respect to
In some embodiments, the method 400 includes while the first container is expanding or the first container is in the expanded configuration, driving a stirrer in the first container (step 408). For example, while the dispenser 300 expands the container 308 or when the container 308 is in the expanded configuration, the dispenser 300 drives a stirrer in the container 308, as described with respect to
In some embodiments, the method 400 includes while the first container is expanding or the first container is in the expanded configuration, mixing, with the stirrer, a powder and the water in the first container to create the culture media (step 410). For example, while the dispenser 300 expands the container 308 or when the container 308 is in the expanded configuration, the stirrer in the container 308 mixes a powder (e.g., cell culture solution (e.g., cell culture media) powder) and the injected water, as described with respect to
In some embodiments, the method 400 includes dispensing the culture media into a second container (step 412). For example, after the powder and the water finish mixing and culture media is created, the dispenser 300 dispenses the culture media into a second container 306 from the first container 308. As another example, as described with respect to
In some embodiments, the method 400 includes prior to dispensing the culture media into the second container, removing a cover of the second container. For example, prior to dispensing the culture media into the second container 306, the dispenser 300 unscrews a cap of the second container 306. As another example, as described with respect to
In some embodiments, the method 400 includes providing a filter. For example, prior to dispensing the culture media into the second container 306, a suitable filter, as described herein, is provided (e.g., by the dispenser 300). In some embodiments, the culture media is dispensed into the second container through the filter. For example, prior to dispensing the culture media into the second container 306, the filter removes undesired content (e.g., contaminate) from the solution in the first container 308 before the culture media is dispensed into the second container 306. As another example, as described with respect to
In some embodiments, the method 400 includes collapsing the first container from the expanded configuration to the collapsed configuration. For example, after the mixing the powder and the water and/or when the culture media is ready to be dispensed into the second container 306, the container 308 is collapsed from the expanded configuration (e.g., by the dispenser 300) to empty the content of the container. As another example, as described with respect to
In some embodiments, the method 400 includes performing inline testing of culture media. For example, prior to dispensing the culture media (e.g., into the second container 306, into the second container 606, into a bioreactor) or prior to allowing retrieval of the second container (e.g., the media is tested before the dispenser door opens for retrieval), the culture media is tested for quality, as described with respect to the description of dispenser 600.
In some embodiments, the method 400 includes refrigerating the cell culture solution. For example, prior to dispensing the culture media (e.g., into a bioreactor) or prior to allowing retrieval of the second container (e.g., the media is stored and refrigerated before the dispenser door opens for retrieval), the culture media is refrigerated at a temperature of −10−4 degrees Celsius, as described with respect to the description of dispenser 600.
In some embodiments, the method 400 includes transporting the cell culture solution to a destination and while transporting the cell culture solution, heating the cell culture solution. In some embodiments, heating the cell culture solution comprises heating a tube transporting the cell culture solution to a same temperature as the destination. For example, as described with respect to the description of dispenser 600, while the cell culture solution is transported or guided to a destination via a tube, the tube is heated to a same temperature as the destination. As an example, the tube is heated to a same temperature as a coupled bioreactor (e.g., advantageously maintaining a condition of the cell culture solution prior to dispensing the cell culture solution into the bioreactor). In some embodiments, the tube is heated to a temperature of 30-40 degrees Celsius (e.g., 37 degrees Celsius).
Additional examples and exemplary advantages associated with method 400 are described with respect to
In some embodiments, the method 500 includes providing a rigid first end (step 502). For example, the first end 102 is provided for manufacturing container 100. As another example, the first end 102 is provided for manufacturing container 150. In some embodiments, the first end is formed by at least one of stamping, molding, and 3-D printing. It is understood that described methods of forming the first end are not meant to be limiting.
In some embodiments, the first end is rectangular or circular. In some embodiments, the first end includes at least one of PLA and PCL. In some embodiments, the first end includes a recyclable material. In some embodiments, providing the first end includes forming a tongue or a groove (e.g., guides 122, guides 172) on the first end configured to, during insertion of the container into a dispenser (e.g., dispenser 300), couple the container to a complimentary groove or tongue on the dispenser. In some embodiments, the first end includes interfacing features (e.g., for stacking, as described with respect to
In some embodiments, the rigid first end comprises an opening. The opening may be advantageously used for other steps of method 500 before being covered by an access port (e.g., access port cover 124, access port cover 174). In some embodiments, the method 500 includes providing a cover configured to occlude the opening. For example, an access port cover (e.g., access port cover 124, access port cover 174) is provided to occlude the opening of the rigid first end.
In some embodiments, the method 500 includes locating a QR code associated with the cell culture solution (e.g., cell culture media) powder on the rigid first end. For example, QR code 120 is located on the access port cover 124, or QR code 170 is located on access port cover 174. It is understood that the illustrated locations of the QR code are not meant to be limiting. The QR code may be located on other parts of the container.
In some embodiments, the method 500 includes providing a rigid second end (step 504). For example, the rigid second end 104 is provided for manufacturing container 100. As another example, the rigid second end 154 is provided for manufacturing container 150. In some embodiments, the second end is formed by at least one of stamping, molding, and 3-D printing. It is understood that described methods of forming the second end are not meant to be limiting.
In some embodiments, the rigid second end comprises a tapered surface on an interior to the container (e.g., as described with respect to
In some embodiments, the method 500 includes providing a middle portion (step 506). For example, the middle portion 106 is provided for manufacturing container 100. As another example, the middle portion 156 is provided for manufacturing container 150. In some embodiments, the middle portion is deformable. In some embodiments, when the container is in an expanded configuration, the middle portion include a rectangular cross-section (e.g., as describe with respect
In some embodiments, the method 500 includes providing an inlet (step 508). In some embodiments, the inlet is located on the first end. For example, the inlet 108A or inlet 108B is provided for manufacturing container 100. As another example, the inlet 158A or inlet 158B is provided for manufacturing container 150. In some embodiments, the method 500 includes fluidly coupling the inlet to a region (e.g., region 126, enclosed by the first end, the second end, and the middle portion) of the container. In some embodiments, the method 500 includes attaching an adapter to the inlet. In some embodiments, the adapter comprises at least one of a Luer Lock adapter and a PVT adapter.
In some embodiments, the method 500 includes providing a second inlet located on the rigid first end. For example, the inlet 108B or inlet 108A is provided for manufacturing container 100. As another example, the inlet 158B or inlet 158A is provided for manufacturing container 150. In some embodiments, the method 500 includes positioning the first and second inlets so that they are parallel. For example, the inlets 108A and 108B are located in a parallel configuration in container 100. As another example, the inlet 158A and 158B are located in a parallel configuration provided in container 150.
In some embodiments, the method 500 includes providing an outlet (step 510). In some embodiments, the outlet is located on the second end. For example, the outlet 110 is provided for manufacturing container 100. As another example, the outlet 160 is provided for manufacturing container 150. In some embodiments, the method 500 includes fluidly coupling the outlet to a region (e.g., region 126, enclosed by the first end, the second end, and the middle portion) of the container. In some embodiments, the method 500 includes mounting the outlet on a spring mechanism. In some embodiments, the method 500 includes attaching an evacuation tube to the outlet. In some embodiments, the evacuation tube includes at least one of a Luer Lock fitting and a sealing nozzle. In some embodiments, the evacuation tube is bendable or flexible.
In some embodiments, the method includes occluding the outlet with a material on the second end. The material occluding the outlet is configured to tear or break in response to an applied pressure (e.g., 5-10 psi) above a threshold pressure (e.g., 2-5 psi). In some embodiments, the material occluding the outlet is different than the material of the second end. In some embodiments, the material occluding the outlet has an area of 1 cm2.
In some embodiments, the method 500 includes attaching the middle portion to the first end and the second end (step 512). For example, the middle portion 106 is attached to the first end 102 and to the second end 104 for manufacturing container 100. As another example, the middle portion 156 is attached to the first end 102 and to the second end 154 for manufacturing container 150. In some embodiments, attaching the middle portion to the first end and the second end comprises gluing the middle portion to the first end and to the second end. As an exemplary advantage, plastic components included in the container are reduced. In some embodiments, the method 500 includes providing a seal between the rigid first end and the middle portion.
In some embodiments, the method 500 includes loading cell culture solution (e.g., cell culture media) powder in the region. In some embodiments, the cell culture solution (e.g., cell culture media) powder is loaded into the region (e.g., region 126) through an opening (e.g., to be covered by access port cover 124, to be covered by access port cover 174) of the container. In some embodiments, after the container content (e.g., cell culture solution (e.g., cell culture media) powder) is loaded through the opening, an access port cover (e.g., access port cover 124, access port cover 174) covers the opening. In some embodiments, the cell culture solution (e.g., cell culture media) powder is loaded into the region through an inlet of the container. In some embodiments, the cell culture solution powder is loaded in the region after attaching the deformable middle portion to the first end and second end. In some embodiments, the cell culture solution powder is loaded in the region prior to attaching the deformable middle portion to the first end and second end.
In some embodiments, loading cell culture solution (e.g., cell culture media) powder in the region includes providing a powder sachet, as described herein, comprising the cell culture solution (e.g., cell culture media) powder. In some embodiments, the method 500 includes attaching the powder sachet to the rigid first end.
In some embodiments, the method 500 includes pre-granulating the cell culture solution (e.g., cell culture media) powder by spray addition of a pH correcting agent. For example, prior to loading the cell culture solution (e.g., cell culture media) powder into the container, the cell culture solution (e.g., cell culture media) powder is pre-granulated by spray addition of a pH correcting agent to advantageously control a pH level of the cell culture solution (e.g., cell culture media) powder. In some embodiments, the method 500 includes providing a pH sensor sensing a pH level associated with the cell culture solution (e.g., cell culture media) powder (e.g., a pH sensor to sense the pH level of the cell culture solution (e.g., cell culture media) powder). In some embodiments, the method 500 includes providing a dissolution sensor (e.g., to monitor the solubility of container contents).
In some embodiments, the method 500 includes providing a stirrer. In some embodiments, the stirrer comprises PTFE. Additional exemplary stirrers are described herein, and for the sake of brevity, they are not described again. In some embodiments, the stirrer is loaded into the region through an opening (e.g., to be covered by access port cover 124, to be covered by access port cover 174) of the container. In some embodiments, after the stirrer is loaded through the opening, an access port cover (e.g., access port cover 124, access port cover 174) covers the opening. In some embodiments, the stirrer is loaded into the region through an inlet of the container.
In some embodiments, the method 500 includes providing a barrier in the middle portion separating the cell culture solution (e.g., cell culture media) powder from at least one of the rigid first end and the rigid second end. In some embodiments, providing the barrier further comprises folding the middle portion to create the barrier. For example, when the container is in the collapsed configuration, the middle portion (e.g., a foldable bag) is folded such that the folds of the middle portion serves as sealed barriers (e.g., the content is separated from at least one of the first end and the second end by the barrier) for the content in the barrier. In some embodiments, a barrier is provided, and the barrier is not a part of the middle portion, as described herein.
In some embodiments, the barrier of the middle portion is created when the container changes from the expanded configuration to the collapsed configuration (e.g., when the container content is being loaded, after the content is loaded, after a first content is loaded and before a second content is loaded). In some embodiments, as the container changes from the expanded configuration to the collapsed configuration, a tool (e.g., an off-center slit that the middle portion passes through) causes the middle portion to fold in a specific manner, such that the fold of the middle portion (e.g., the fold of a bag) creates the barrier.
In some embodiments, the method 500 includes creating a vacuum in the region. In some embodiments, creating the vacuum in the region comprises removing air from the region through an opening of the rigid first end (e.g., inserting a tube through the opening to remove air from the region 126). In some embodiments, after the vacuum is created, an access port cover (e.g., access port cover 124, access port cover 174) covers the opening and maintains the vacuum in the region. In some embodiments, the vacuum is created through an inlet of the container.
In some embodiments, the method 500 includes providing a filter having a pore size of 0.22-1 μm. In some embodiments, the method 500 includes attaching a filter to the outlet. For example, the filter is coupled to the outlet of the container (e.g., outlet 110, outlet 160) externally (e.g., as described with respect to
Additional examples and exemplary advantages associated with method 500 are described with respect to
In some embodiments, the dispenser 600 includes at least one pump (not shown). In some embodiments, the dispenser 600 includes a pump for pumping air into the container 608 (e.g., during expansion the middle portion of the container 608). In some embodiments, the dispenser 600 includes a pump for pumping air out of the container 608 (e.g., during collapsing of the middle portion of the container 608). In some embodiments, the dispenser 600 includes a pump for cleaning and/or sterilizing the chamber after use. For example, the pump drains liquid in the chamber and/or pumps in water or a cleaning solution for cleaning and/or sterilizing the chamber.
In some embodiments, the dispenser 600 includes a first pump that is configured to apply a first pressure and is configured to apply a second pressure. In some embodiments, the first and second pressures are different. In some embodiments, the dispenser 600 includes a pump that is configured to apply variable pressures. In some embodiments, by including a pump or pumps that can apply different pressures, the dispenser 600 advantageously enables different tasks to be performed (e.g., different tasks that one pump applying one pressure would not be able to perform). For example, a pump applies a first pressure (e.g., 10-30 psi) for pumping air into the container 608. As another example, a pump applies a second pressure (e.g., less than 12 psi, not pressurized) for pumping air out of the container 608. As yet another example, a pump applies a third pressure (e.g., less than 12 psi, not pressurized) for cleaning and/or sterilizing the chamber after use.
In some embodiments, some components of dispenser 600 are the components described with respect to
In some embodiments, the GUI 602 indicates a state of the dispenser 600 and/or presents selectable inputs for a user to control the dispenser 600 (e.g., for manufacturing cell culture media). For example, as illustrated in
In some embodiments, in response to receiving a selection of the GUI object 622A, the cell culture manufacturing process begins. For example, as illustrated in
In some embodiments, as illustrated in
In some embodiments, as illustrated in
In some embodiments, in response to selection of the GUI object 622C, the dispenser 600 proceeds to a next step of the cell culture manufacturing process. In some embodiments, as illustrated in
In some embodiments, as illustrated in
In some embodiments, as illustrated in
In some embodiments, the structure of the baffle is concentric to the container 608 such that the structure supports the middle portion of the container while a force is acting on the middle portion (e.g., to prevent the middle portion for breaking). For example, as illustrated, the two components of the baffle 618 include planes that are parallel to the middle portion, optimizing points of contact between the middle portion and the baffle and hence, optimizing support for the middle portion.
It is understood that the described baffle geometry and mechanism are not meant to be limiting. The baffle may include different number of components (e.g., different than two) or different shapes than described, as long as the baffle is able to provide support for the middle portion of the container 608 when a force is acting on the middle portion. For example, the baffle may include four components (e.g., each component supporting a quarter of the middle portion). As another example, the shape of the baffle may be cylindrical, in a shape of a hexagonal prism, in a shape of an octagonal prism, and the likes.
In some embodiments, the baffle 618 advantageously provides support for the material of the middle portion (e.g., middle portion 106) of the container 608, while the container 608 is in the expanded configuration and a force acts on the middle portion (caused by, e.g., mixing of the cell culture solution, pressured applied (e.g., 5-10 psi) in the middle portion). By providing support for the middle portion of the container while a force acts on the middle portion, the baffle may allow a more compact (e.g., thinner) material to be used for manufacturing the middle portion. A more compact middle portion material may increase the efficiency of content storage and/or allow the ends of the container (e.g., the first end 102, the second end 104) to mate uniformly (e.g., allowing the container to close properly) when the container is in the collapsed configuration. For example, a thinner middle portion material allow more cell culture media powder to be stored and the container to be closed properly when the container is in the collapsed configuration.
In some embodiments, after the container 608 is in the expanded configuration, the magnetic field generator 616 (as described with respect to
In some embodiments, the magnetic field generator 616 continues to magnetically drive the stirrer until a desired cell culture solution is created. In some embodiments, the magnitude, direction, and/or frequency may change to drive the stirrer in a different manner while the cell culture solution is being created. In some embodiments, the solution may be stirred for a pre-determined amount of time (e.g., based on the container content). In some embodiments, the dispenser 600 includes a sensor (not shown) (e.g., a pH sensor, a timing sensor, an optical system for quantifying turbidity (e.g., in the solution)) for determining whether the desired cell culture solution has been created. In some embodiments the magnetic field generator 616 returns to its initial location after the desired cell culture solution has been created (e.g., stirring is completed).
In some embodiments, as illustrated in
In some embodiments, the second container handling mechanism 620 raises the second container 608 toward the container 606 in accordance with a determination that the desired cell culture solution has been created (e.g., after a pre-determined amount of time, the dispenser 600 determines that the solution has been created (e.g., based on sensor data)).
In some embodiments, after the second container 608 is raised at a suitable distance (e.g., a distance that allows the cell culture solution to be cleanly or efficiently dispensed) from the filter, the dispenser 600 causes the cell culture solution to be dispensed from the container 606. In some embodiments, the dispenser applies a pressure (e.g., 5-10 psi, using a pump fluidly coupled to the container, by collapsing the container 608 back to the collapsed configuration) in the middle portion of the expanded container to push the cell culture solution toward the outlet of the container 606. In some embodiments, the outlet is occluded by a material that is configured to tear or break in response to an applied pressure (e.g., 5-10 psi) above a pressure threshold (e.g., 2-5 psi). As such, in response to the pressure applied by the dispenser in the middle portion, the material occluding the outlet tears or breaks, allowing the cell culture solution to exit the outlet, pass through the filter coupled to the outlet, and be dispensed to the second container 608, as illustrated. In some embodiments, after the second container 608 is raised at the suitable distance from the filter, the dispenser 600 collapses the container 608 back to the collapsed configuration (e.g., the slots 604 moves towards each other to move the first and second ends of the container 608 closer to each other), pushing the cell culture solution out of the container 608 through the container's outlet.
In some embodiments, after the desired cell culture solution is dispensed into the second container 608, the second container handling mechanism 620 lowers the second container 608 back to its initial location. In some embodiments, after the desired cell culture solution is dispensed into the second container 608, the filter coupling mechanism 614 disposes the filter, as described with respect to
In some embodiments, as illustrated in
In some embodiments, as illustrated in
In some embodiments, during this time, the GUI 602 includes a GUI object 622E. A user may select the GUI object 622E after the container 608 and second container 606 are retrieved (e.g., to inform the dispenser 600 of the retrieval of the containers). In response to selection of the GUI object 622E, the dispenser 600 closes the door 610. In some embodiments, in response to selection of the GUI object 622E, the GUI 602 updates to display the home page. In some embodiments, the GUI object 622E does not appear until the container 608 and second container 606 are removed from the dispenser 600 (e.g., based on sensors of the dispenser 600). In some embodiments, the GUI object 622E is not selectable until the container 608 and second container 606 are removed from the dispenser 600 (e.g., based on sensors of the dispenser 600).
In some embodiments, in response to the door 610 closing, the dispenser 600 prepares for manufacturing another cell culture solution (e.g., the dispenser 600 is sterilized, as described with respect to
In some embodiments, the dispenser 600 is configured for inline testing of cell culture solution. For example, the inline testing of media is performed to determine the quality of the media (e.g., amino acid levels, protein levels, salt levels, and the likes). In some embodiments, the inline testing of the media is performed by a sensor of the dispenser 600. In some embodiments, the dispenser 600 manufactures larger values of cell culture media (e.g., for a bioreactor). The inline testing advantageously confirms media suitability prior to dispensing the media into a bioreactor to prevent lower quality media from being dispensed into cells in the bioreactor (e.g., lower quality media may kill thousands or millions of dollars worth of cells in the bioreactor).
In some embodiments, the dispenser 600 is configured to refrigerate the cell culture solution. In some embodiments, the cell culture solution is refrigerated at a temperature of −10−4 degrees Celsius. For example, prior to retrieval of the cell culture solution (e.g., retrieval second container 606, retrieval of a container storing the cell culture solution, dispensing of the cell culture solution into a bioreactor), the chamber of the dispenser provides refrigeration (e.g., by lowering the temperature of the chamber) until the cell culture solution is ready for retrieval (e.g., retrieval second container 606, retrieval of a container storing the cell culture solution, dispensing of the cell culture solution into a bioreactor). In some embodiments, by refrigerating the cell culture solution, the dispenser advantageously allow the cell culture solution to be stored at ideal conditions and prevent cell culture solution degradation. In some embodiments, the cell culture solution is refrigerated at a different, thermally isolated chamber of the dispenser (e.g., different from a chamber for manufacturing cell culture solution), advantageously allowing a first cell culture solution to be stored and refrigerated in this chamber while a second cell culture solution is being manufactured in another chamber of the dispenser.
In some embodiments, the dispenser 600 comprises a tube configured to be heated or is configured to couple to a tube configured to be heated. In some embodiments, the tube is configured to transport or guide the cell culture solution to a destination (e.g., a bioreactor, a second container). In some embodiments, while the cell culture solution is transported or guided to the destination, the tube is heated to a same temperature as the destination. For example, the tube is heated to a same temperature as a coupled bioreactor (e.g., advantageously maintaining a condition of the cell culture solution prior to dispensing the cell culture solution into the bioreactor). In some embodiments, the tube is heated to a temperature of 30-40 degrees Celsius (e.g., 37 degrees Celsius).
Although the content of the container is described with respect to cell growth (e.g., cell culture solution (e.g., cell culture media)), it is understood that the description of the container content is not strictly limited to cell growth. For example, cell growth may include tissue growth. As another example, cell culture may include tissue culture.
