[0002] Biological cells are extremely sensitive to environmental conditions, and even small changes in temperature, humidity, oxygen content, etc. may have a significant impact on their activity and function. A suitable preservation device can ensure that the cells remain in good condition during the experiment, providing a guarantee for the accuracy and repeatability of the experiment. In the prior art, the humidity and oxygen content in the test tubes where biological cells are stored can be easily controlled, and biological cells need to be stored in an incubator or refrigerator for refrigeration or constant temperature storage.

[0003] Low-temperature refrigeration device, principle: lowering the temperature can slow down the metabolic activity of cells and prolong the survival time of cells; ultra-low-temperature freezing device, principle: using extremely low temperatures (usually at -80℃ or even lower liquid nitrogen temperature -196℃) to almost completely stop cell metabolism; constant temperature incubator, principle: providing a stable temperature, humidity and gas environment to simulate the growth conditions of cells in the body.

[0004] Regardless of the preservation method, the lid of the storage box needs to be opened when storing and accessing the test tubes storing biological cells. Opening the entire lid will cause a large amount of temperature to dissipate, causing temperature imbalance in the box and affecting the activity of the cells. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a single-tube taking-out and temperature-preserving device.

[0006] The technical solution adopted to solve the above technical problems is: a sample preservation device for biological cell experiments, including a top sealing cover arranged at the top of an insulating outer cylinder, a temperature regulator is fixedly connected to the center of the upper surface of the top sealing cover, and a plurality of test tube storages distributed in a circle are arranged on the surface of the top sealing cover.

[0007] Through the above technical solution, power is stored through the temperature regulator and the temperature inside the thermal insulation outer cylinder is adjusted. The top sealing cover and the thermal insulation outer cylinder form an enclosed space, which can effectively avoid temperature imbalance and make the temperature inside the thermal insulation outer cylinder constant. The temperature regulator is more energy-saving and power-saving, and cell storage tubes can be stored through the test tube storage.

[0013] Through the above technical solution, the lifting ring can limit the cell storage test tube with an arc-shaped bottom, and at the same time lift it up through the elastic arc block. When the ejection spring pulls the control handle, the limiting groove and the positioning pin are separated, and the test tube rack is ejected, making it convenient to take and place the cell storage test tube.

The label bar can record the cell information at the corresponding position, and the corresponding cells can be found on the outside of the thermal insulation outer cylinder without opening the flip cover, thereby avoiding temperature loss caused by opening the flip cover for a long time. When the transparent acrylic material passes through the flip cover, the light of the LED lamp will shine through, indicating that a cell storage test tube is placed at this position, and the control handle can conveniently pull the test tube storage out of the thermal insulation outer cylinder.

Since the label column 4 and the flip cover 6 are fixed through, the label column 4 position is illuminated, indicating that the test tube storage at this position has placed the cell storage test tube 8, and the storage cell information is filled in the label position, and the label is inserted into the label column 4, which is convenient for finding the required cells later; The required cell sample is found through the label column 4, and the control handle 7 is lifted up to pull out the test tube rack 9, and the cell storage test tube 8 is pressed downward.
