Abstract:
1. A cryogenic storage device suitable for cryogenic storage of biological samples, said cryogenic storage device comprising: (a) a sample carrier device which is adapted to accommodate the samples, (b) a cryogenic container which is adapted to accommodate the sample carrier device, (c) a container cooling device adapted to cool the cryogenic container, (d) an intermediate storage container adapted for intermediate storage of the sample carrier device, (e) a transport device adapted to move the sample carrier device between the cryogenic container and the intermediate storage container, (f) a sensor device adapted to detect at least one operation parameter of the cryogenic storage device, (g) a control device in communication with the sensor device and the transport device forming a control loop therefrom, the control device being configured to detect a predetermined malfunction operation state of the cryogenic storage device and to automatically send control signals for activation purposes to the transport device based on the detected predetermined malfunction operation state, and (h) an intermediate storage cooling device configured to cool the intermediate storage container, wherein the intermediate storage cooling device is activated as a function of an output signal from the sensor device upon detection of the predetermined malfunction operation state, and the transport device is activated as a function of the output signal from the sensor device upon detection of the predetermined malfunction operation state of the cryogenic storage device, so that the sample carrier device is moved from the cryogenic container into the cooled intermediate storage container, and the predetermined malfunction operation state includes at least one of an overfilling of the cryogenic container with liquid nitrogen, and undue heating of the samples in the cryogenic container, diminishing insulation of the cryogenic container, a rack defect, and a cryogenic container defect.
