Ultralow-temperature cell transportation and storage device for stem cell research

Abstract

The invention discloses an ultralow temperature cell transportation and storage device for stem cell research, the transportation and storage device comprises a transportation box, a storage box is arranged in the transportation box, a cooling pipe is arranged above the storage box in the transportation box, a control box is arranged below the storage box, the cooling pipe is connected with the storage box through a pipeline, and the control box is connected with the storage box through a pipeline. The control box enables the storage box to be kept in a vertical state. The cooling pipe extracts outside air and heats and sterilizes the air through the hot end generated by the Peltier effect, the cooling pipe cools the hot air through the cold end generated by the Peltier effect again, moisture in the hot air is condensed into low-temperature water, the hot air is cooled into cold air, the cooling pipe conveys the low-temperature water into the storage box, and the storage box stores the low-temperature water. The storage box cools the stem cells through low-temperature water, the cooling pipe injects cold air into the box body of the storage box, the cold air cools the box body, and the situation that the cold-heat exchange between the box body and the low-temperature water affects the effect of refrigerating the stem cells is prevented.

Description

technical field [0001] The invention relates to the technical field of low-temperature cell transportation, in particular to an ultra-low temperature cell transportation and storage device for stem cell research. Background technique [0002] Stem cells have the potential to regenerate various tissues and organs as well as the human body. They are not fully differentiated and immature cells. They have the title of "universal cells" in the medical field. During the transportation of stem cells, the interior of the transportation storage device needs to maintain an ultra-low temperature environment, and the low temperature allows them to enter a dormant state, so that the stem cells can be revived to treat diseases when needed. During the transportation process, the stem cells are stored in the storage device, and the inside of the storage device is easily affected by the external temperature, resulting in uneven temperature, which in turn affects the storage effect of the ste...

During the transportation process, stem cells are stored in the storage device, and the inside of the storage device is easily affected by the external temperature, resulting in uneven temperature, which in turn affects the storage effect of stem cells

[0003] Existing low-temperature storage devices for stem cells often use liquid nitrogen to freeze and store stem cells, but liquid nitrogen is volatile, so that liquid nitrogen decreases significantly with the passage of time, and adding liquid nitrogen to traditional low-temperature storage devices for stem cells It will be more troublesome, and the number of stored stem cells is relatively small, which results in the need to use more stem cell storage devices, resulting in a certain waste of resources and increased transportation costs
