Description

Technical Field

[0001] The present application relates to the field of biological sample technology, and in particular to a biological sample placement device. Background Art

[0002] With the rapid development of the biopharmaceutical industry, large-scale biobanks have emerged, and the storage capacity of biological samples has become larger and larger. Generally, biological samples such as tissues and cells in clinical or laboratory settings are placed in cryopreservation boxes, which are then placed in biological sample placement devices for storage or temporary storage.

[0003] The biological sample placement device has a refrigeration system, which is used to provide cold air to the receiving chamber of the biological sample placement device, thereby ensuring the activity of the biological sample. The biological sample placement device has a top opening. Due to the principle that cold air naturally sinks and hot air floats, setting the opening at the top can reduce the degree of external hot and humid air entering the receiving chamber.

[0004] The top opening can be used to take out and put the cryoboxes. A plurality of trays can be arranged in the receiving chamber of the biological sample placement device, and the trays are used to place the cryoboxes. In order to prevent a large amount of cold air from leaking out and to prevent a large amount of hot and humid air from entering the receiving chamber, the top opening will not be designed to be too large. Therefore, the tray needs to be moved to ensure that each cryobox can pass through the top opening.

[0005] In the related art, there is already such a biological sample placement device, see the patent application with application number CN202010943255.7, a cryo box is placed on the tray, and the tray can rotate so that each tray can be moved to the top. The difficulty of this type of structure is how to ensure that the tray keeps the side with the cryo box facing up at all times when rotating to prevent the cryo box from falling. Figure 2 It is connected into a W shape by many connecting rods to ensure that the side with the frozen boxes always faces upward when the tray rotates. It has a complex structure, is unstable in low temperature environments, has many connection points, and is easily stuck due to frost at the connection points. Summary of the invention
