  • Patent number: 11441115
    Abstract: When detachment of a cell sheet from a culture dish has started at an unintended timing, immediately detach the cell sheet from the culture dish while preventing generation of wrinkles and the like in the cell sheet. A cell culture device captures an image of cells in the culture dish, and controls a cooling mechanism and a shaking mechanism based on the image so as to shake the cells while cooling them.
    Type: Grant

  • Publication number: 20170226456
    Abstract: This invention provides a cost-effective technique for mass-production of a cell culture vessel that allows mass cell culture to be performed in a manner that allows cells to be stably detached from the culture vessel. Specifically, the invention provides a method for producing a cell culture vessel suitable for large-capacity culture comprising cutting a long-sized cell support film to obtain a sheet-like cell support film, fixing the film to a first member, which is not closed, and bonding other members thereto. Thus, a cell culture vessel comprising a container section in which a cell support film is fixed to an inner wall surface can be produced.
