Definitions
- the invention relates to mixing the contents of a flexible container for biopharmaceutical use. More specifically, it relates to a container for biopharmaceutical use, a rigid assembly for receiving and holding the flexible container of such a container for biopharmaceutical use and, finally, a method for implementing such a container for biopharmaceutical use.
- biopharmaceutical product a product derived from biotechnology - culture media, cell cultures, buffer solutions, artificial nutrition liquids, or a pharmaceutical product or more generally a product for use in the medical field.
- a container for biopharmaceutical use comprises first and foremost a flexible container having a flexible wall limiting forward an interior space capable of receiving the biopharmaceutical product.
- a flexible container or pouch is disposable, closed, sealed, sterile, plastic such as polyethylene or a complex comprising polyethylene.
- Such a container comprises means of introduction into the interior space and extraction means from the interior space of the biopharmaceutical product or components thereof, able to be brought, according to the moments and the needs to the open state or closed state.
- Such pockets are known whose two large walls are directly joined to one another. Once expanded, such bags have a limited volume and remain relatively thin, which justifies that they are often called “pillow” pockets, or pockets “2D” (D meaning dimensions).
- pockets “2D” D meaning dimensions.
- 3D pockets which comprise two large walls connected by and welded to two side gussets, which can be folded flat or folded unfolded, the volume can then be at least 50 liters, up to 3000 liters or more.
- Such 3D pockets are described in WO00 / 04131a or sold under the trade mark FLEXEL ® 3D.
