CELL CULTURE CONTROL DEVICE, CELL CULTURE DEVICE PROVIDED WITH SAME, CELL CULTURE CONTROL METHOD, AND CELL CULTURE CONTROL PROGRAM

A PC (10) comprises a measurement unit (12), a consumption rate calculation unit (13), a culture medium replacement detection unit (15), and a next step transition determination unit (16). The measurement unit (12) acquires the amount of consumed glucose from the result of continuously measuring the concentration of glucose contained in a culture medium (X) of a culture vessel (20). The consumption rate calculation unit (13) calculates the consumption rate at which glucose is consumed by differentiating the amount of glucose consumed. The culture medium replacement detection unit (15) detects that the culture medium (X) in the culture vessel (20) has been replaced or added. When the culture medium (X) is replaced or added, the next step transition determination unit (16) determines whether or not to proceed to the next step according to whether or not the consumption rate after the replacement or addition of the culture medium (X) calculated by the consumption rate calculation unit (13) satisfies a specific condition.
