Reuse Bioreactor Bag Kit (RBBK) · 模型 27324
The Reuse Bioreactor Bag Making Kit (RBBK) is a solution inspired by bag technology as used in Gen-1 and Gen-2 bioreactors. The development of bioprocesses in space missions faces several technical and logistical challenges. Gravity on Earth allows phase separation at levels, facilitating an orderly movement of fluids. In microgravity, the dominant force is viscosity, causing liquids and gases to separate into bubbles. The liquid of interest is not always positioned at the inlet/outlet ports, which makes its operation extremely diicult, especially when using rigid vessels. The proposed new RBBK design introduces significant improvements in terms of reusability, on-site manufacturing and compatibility with existing infrastructure. Its modular design allows it to be adapted to dierent uses beyond bioreactors, maximizing eiciency and reducing the need for disposable supplies. It consists of three main 3D printed subassemblies: Subset bag (10-SubSet-bag.stp) : Made of gas-permeable plastic, it allows for eicient exchange of 𝑂, 𝐶𝑂 and ethylene. Luer Lock Valve Subset (20-SubSet_luer-lock.stp) : Facilitates the injection and withdrawal of fluids through a LUER LOCK port Hermetic sealing press subassembly (30-press-x02.stp) : Allows the reuse of bags while allowing access to their interior for cleaning. Each component has been designed to use appropriate materials for its function and to be manufactured with the 3D printer available on the ISS. The simple and lightweight structure of the RBBK (less than 50g), together with its reusability and recyclability, make it a very viable option for building bioreactors capable of handling liquid content in microgravity environments during space missions.
