  • Patent number: 10704991
    Abstract: A cell aspiration support system includes an image acquisition unit, an image processing unit, a display unit, an operation control unit and a cooling unit. The image acquisition unit acquires an image of the group of cells. The image processing unit identifies a cell from the acquired image to calculate feature quantities of each cell, and detects a cell whose feature quantities satisfy predetermined conditions. The display unit displays information relating to the group of cells in a state in which the detected cell is distinguishable. When receiving designation of the specific cell based on the information, the operation control unit moves the cell culture container such that a specific cell is placed at a predetermined aspiration position and moves an aspiration tip to the aspiration position. The cooling unit holds a specimen rack storing an aspirated tip after aspiration and cools the tip.
