Cell detection device and cell detection method

A cell detection device that detects a cell in a specimen, comprising:

• a sealed container having a sealable specimen introduction portion, a culture portion that holds a culture solution, an extraction reagent portion that holds an extraction reagent, and a luminescent reagent portion that holds a luminescent reagent;
• a contact mechanism that controls contact of the culture solution, the extraction reagent, and the luminescent reagent;
• a photodetector disposed outside the sealed container at a position that detects luminescence light emitted from the luminescent reagent in the luminescent reagent portion;
• and
• a processor configured to calculate an amount of luminescence from a detection signal received from the photodetector and determine growth of the cell based on a temporal change in the amount of luminescence, wherein
• the extraction reagent is a reagent for extracting a substance necessary for a luminescence reaction with the luminescent reagent from the cell to obtain an extraction solution,
• the luminescent reagent is a reagent that emits light when brought into contact with the extraction solution,
• the culture solution, the extraction reagent, and the luminescent reagent are disposed separately in the sealed container,
• the contact mechanism is disposed at an end of the sealed container and is movable airtightly in a direction of an interior of the sealed container, and is constructed to have a plurality of positions along the direction of the interior of the sealed container comprising a first position which brings a part of the culture solution to which the specimen is added and the extraction reagent into contact with each other to obtain the extraction solution, and a second position which brings the extraction solution and the luminescent reagent into contact with each other, and
• the extraction reagent portion is disposed between the culture portion and the luminescent reagent portion.
