  • Patent number: 11221475
    Abstract: A coverslip for cell culture, capable of achieving seamless adhesion between the coverslip for cell culture and a target culture device, so as to solve the technical problem that cell suspension flows into gaps between the coverslip and a culture dish. Moreover, the coverslip for cell culture has exquisite structure, and is easy to carry out batch experiment and comparison. The coverslip is flake-like with upper and lower surfaces being parallel to each other, and comprises: a coverslip substrate (1) and sub-coverslips (2); the coverslip substrate (1) is provided with at least N hollowed-out parts (11); the sub-coverslips (2) are fixedly connected in the hollowed-out parts (11) by means of M fragile connecting pieces (3), wherein both N and M are natural numbers which are not related to each other.

  • Patent number: 11168294
    Abstract: A three-dimensional cell culture scaffold and preparation method thereof. The preparation method comprises the following steps: designing, according to a shape of a cell culture device, a shape of the three-dimensional cell culture scaffold; printing once by a 3D printer to form the three-dimensional cell culture scaffold; performing a surface treatment, by a surface treating agent, on the three-dimensional cell culture scaffold manufactured by 3D printing to obtain a resultant three-dimensional cell culture scaffold. By adopting a three-dimensional printing technology to manufacture a three-dimensional fibrous cell culture scaffold having a three-dimensional fibrous network structure, raw materials and a manufacturing time can be saved, reducing production costs, increasing production efficiency, decreasing power consumption, preventing a flaw in the conventional manufacturing technique, and facilitating large-scale intelligent manufacturing.

  • Patent number: 11028356
    Abstract: Provided are cell culture apparatus and method. The cell culture apparatus comprises a culture column and a perfusion system, the culture column comprising a first and a second tube-connecting caps and a support for cells to attach and grow thereon. The first and the second tube-connecting caps are respectively provided with a perfusion inlet and a perfusion outlet; The perfusion system comprises a culture medium storage device, a perfusion tube and a perfusion pump. A complete and closed culture column is formed in the cell culture device after the cells are inoculated, and the culturing is completed by the perfusion system to avoid contamination.
