Problems solved by technology

These bioreactors have a single function, some instruments are used for cell separation or collection, some are used for the preparation of cell suspension, some are used for mixing cells and materials, some are used for cell and tissue culture, The main disadvantages of these bioreactors are operational complexity, susceptibility to contamination
[0005] The invention patent with the patent number ZL 031106701.2 and the invention name "Cell Reactor", the patent application number is 200910229109.1, the invention patent with the invention name "Polysaccharide Composite Scaffold Perfusion Hepatocyte Reactor System for Evaluation of Drug Hepatotoxicity", patent application No. 200910242907.8, the invention title is "A Cell Reactor and Artificial Liver Support System Including the Reactor". None of these three cell reactors can provide the temperature, humidity and gas conditions required for cell growth. The cell reactor can only be used if it is placed in a carbon dioxide incubator, and the cell reactor and a cell reactor and the artificial liver support system including the reactor cannot realize dynamic cell seeding and dynamic culture

Description

technical field [0001] The invention belongs to the technical field of cell culture equipment or devices, and in particular relates to culture equipment using flowing cell culture fluid in a carbon dioxide environment. Background technique [0002] Traditional cell culture methods, namely two-dimensional cell culture, cause cells to lose their tissue-related functions and cannot accurately reflect the growth of cells in vivo. Although animal models and in vivo experiments can reflect the real internal environment of cell growth, the cost is too high, the process is complicated, and they are restricted by ethics. In vivo environment, all cells are in a kind of three-dimensional space. Three-dimensional cell culture can reproduce cell-cell and cell-matrix interactions, and compared with two-dimensional cell culture, it can more truly reflect the internal environment of cell growth. Therefore, 3D cell culture can bridge the gap between 2D cell culture and animal experiments. ...
