Definitions

  • the invention relates to techniques for the sterile delivery of products for biological uses, and specifically to an apparatus and method for providing sterile delivery of biological products without the need for passing the medium through a filter or sterilizing membrane filter.
  • the methodology currently employed to prepare certain of these reagents involves the use powdered ingredients.
  • these powdered reagents are not sterile when received by the end user, who converts these powdered ingredients into a solution using purified water. Since the solution is not sterile, as the powdered ingredients were not, the solution is then passed through a sterilizing membrane filter and transferred aseptically to a sterile container or culturing vessel.
  • the disadvantage of the above method is that such handling greatly increases the chances of biological contamination and loss or alteration of the product, contamination due to environmental or human exposures, loss due to transfer, and alteration due to removal of certain components during membrane sterilization.
  • the powder medium is stored in a cartridge or bag, which is then subject to gamma irradiation for sterilization. This results in delivering a powdered product to the end user in a sterile state.
  • the cartridge or bag is designed so that the solution can be generated within the unit, eliminating potential opportunities for contamination. Since this invention eliminates the need for post-mixing sterilization, it reduces the potential for loss of product or components, thereby increasing batch-to-batch consistency.
  • Fig. 1 is a view of a powder delivery cartridge of the present invention.
  • Fig. 2 is a view of the reconstituting apparatus for the powder delivery cartridge of the present invention.
  • Fig. 3 is a view of a powder delivery bag of the present invention.
  • Fig. 4 is a view of the reconstituting apparatus for the powder delivery bag of the present invention.
  • the present invention is directed to a method and apparatus for sterile delivery of cell culture products in solution.
  • a method and apparatus for sterile delivery of cell culture products in solution To facilitate the distribution and transport of biological products used in cell cultures, it is desirable when and where possible to reduce the products to a stable powder form.
  • the powder is combined with sterile purified water to generate a liquid solution, which then may be transferred to the cell culture vessel or vessels.
  • Fig. 1 shows the apparatus used in a first embodiment of the present invention, where a powdered medium is contained within a cartridge.
  • Cartridge 1 comprises a hollow cartridge barrel 2 (which may be, but is not limited to, a suitable IV blood filter cartridge), and has end caps 3, tubing 4, tubing connectors 5, and tubing clamps 6 connected at each end.
  • the procedure for assembly and filling of the cartridge 1 involves first connecting tubing connectors 5 to tubing 4, by coating tubing connectors 5 with solvent and inserting them into tubing 4. Tubing clamps 6 are then clamped onto both pieces of tubing 4. Next, tubing 4 is connected to end caps 3 by first applying solvent to end caps 3 and then inserting end cap 3 end into tubing 4 end. One end cap 3 is then attached to barrel 2 by coating the outside edge of the end cap 3 with solvent and connecting it to barrel 2 end. The cartridge 1 is then filled from the other end of barrel 2 with the appropriate amount of powdered medium. Powder should not be present on the inside edge of barrel 2. Finally, the other end cap 3 is attached to the open end of barrel 2, using the procedure outlined above, and the cartridge 1 is labelled to indicate the type and quantity of powdered medium therein.
  • the cartridge is then stored with a desiccant, at a temperature between 2-
  • Fig. 2 The configuration for a suggested apparatus for reconstitution by an end user of medium stored in a cartridge is illustrated in Fig. 2.
  • Reconstitution of the powdered medium is accomplished by connecting cartridge 1 to a reconstituting apparatus 7.
  • Reconstituting apparatus 7 contains an inlet tube 8 which is connected to a source (not shown) of water, preferably WFI-grade water. Water is pumped from its source by a peristaltic pump 9, of any known type for accurate delivery of liquids.
  • the outlet of peristaltic pump 9 is connected to a filter unit 10, preferably containing a sterile 0.2 ⁇ m filter.
  • sodium bicarbonate cartridge 11 Connected in series with filter unit 10 is a sodium bicarbonate cartridge 11, which has at one end tubing 12 which may be connected to the tubing connector 5 on cartridge 1.
  • Sodium bicarbonate is necessary in the reconstitution process to act as a buffer for the powdered medium, but must be packaged separately due to potential problems of carbon dioxide generation.
  • sodium bicarbonate is shown in Fig. 2 as added to the water through cartridge 11, it could, alternatively, be added to the water upstream of the peristaltic pump 9 at the water source, thus eliminating the need for sodium bicarbonate cartridge 11.
  • sodium bicarbonate cartridge 11 should be gamma irradiated for sterilization.
  • the cartridge 1 is connected to tubing 12 on reconstituting apparatus 7 by means of tubing connector 5.
  • sodium bicarbonate cartridge (if necessary) and filter 10 have been connected to peristaltic pump 9 to complete reconstituting apparatus 7.
  • Clamp 6 on cartridge 1 adjacent tubing 12 is then undamped.
  • the unconnected tubing connector 5 on cartridge 1 is then aseptically joined to a sterilized receiving vessel 13.
  • clamp 6 on cartridge 1 adjacent sterilized receiving vessel 13 is undamped.
  • Peristaltic pump 9 is then activated. Liquid flows from its source, through peristaltic pump 9, filter unit 10, sodium bicarbonate cartridge 11, powder cartridge 1 and (as solution) into sterilized receiving vessel 13.
  • Solution is therefore generated and placed into vessel 13 without need for handling or filtering of the solution itself.
  • the solution is sterile due to pre-cartridge filtering of the water and the previous gamma irradiation of the powder medium and sodium bicarbonate.
  • Peristaltic pump 9 is run until the volume of solution generated in vessel 13 is of a desired quantity. Solution in vessel 13 may thereafter be transferred to specific cell culture devices.
  • Fig. 3 shows a second embodiment of the present invention, utilizing a powder delivery bag 14.
  • Powder delivery bag 14, of appropriate manufacture so that it is compatible with cell culture usage generally contains three ports: septum port 15, filling port 16, and dispensing port 17.
  • Filling port 16 and dispensing port 17 consist of flexible tubing (as were the inlets and outlets to cartridge 1) to which are attached tubing clamps 18. During filling, the tubing clamps 18 are undamped, and powder is dispensed into bag 14 through filling port 16. After filling is completed, tubing clamps 18 are clamped to both filling port 16 and dispensing port 17. The bag is then stored with a desiccant, at a temperature between 2-8° C.
  • the contents of the bag are then sterilized using gamma irradiation, generally between 0.5 and 3.0 megaRad. Finally, the bag is shipped, with a desiccant and at a temperature between 2-8° C, to the end user. The end user reconstitutes the powder using the apparatus shown in Fig. 4.
  • the apparatus for reconstitution in powder bag 14 is similar to that used to reconstitute powder in powder cartridge 1.
  • tubing connector 5 is connected between tubing 12 and filling port 16.
  • Dispensing port 17 is connected to sterilized receiving vessel 13.
  • Clamps 18 are then undamped, and peristaltic pump 9 is activated.
  • Liquid flows through pump 9, filter 10, sodium bicarbonate cartridge 11 (if necessary), bag 14, and (as solution) into vessel 13. Accordingly, as in cartridge 1, solution is dispensed into sterile receiving vessel 13 without the need to handle the powder and without the need to filter the solution.
  • Bag 14 may be used for storage of the material for a prescribed period of time.

Abstract

Procédé et appareil destinés au transfert et à la distribution améliorés de milieux biologiques utilisés dans des cultures de cellules tissulaires. Les milieux sont réduits en poudre puis placés dans une cartouche ou un sachet (1). Les milieux sont ensuite stérilisés dans le sachet (1) par l'intermédiaire d'une irradiation gamma. La cartouche ou le sachet (1) est expédié à un utilisateur final, qui reconstitue la poudre sous forme de solution. De l'eau stérilisée est pompée à travers la cartouche ou le sachet (1), et la solution est amenée à sortir par un orifice de sortie pratiqué dans la cartouche ou le sachet (1) et transférée à un récipient stérilisé (13). La solution peut alors être ajoutée à une culture tissulaire. Ce procédé est avantageux dans la mesure où il ne nécessite pas de filtration de la solution pour la rendre stérile, ce qui permet d'éliminer les pertes de produit encourues au cours du processus de filtration. Un autre avantage du procédé réside dans le fait que la poudre n'est pas directement manipulée après la stérilisation, ce qui réduit considérablement les risques de contamination de la solution.
