Description

Technical Field

[0001] This utility model relates to the field of sample storage technology, specifically a biological sample storage device. Background Technology

[0002] Biological sample storage devices are used to properly preserve biological samples, which are of great significance for biological research and medical diagnosis. Common types include low-temperature freezers, which, through precise temperature control systems, can preserve samples at temperatures ranging from -20°C to -80°C or even lower, inhibiting changes in the activity of biomolecules and the growth of microorganisms. This ensures the long-term preservation of valuable samples such as cells and tissues, maintaining their biological activity and integrity, and facilitating subsequent scientific analysis and research.

[0003] A biological sample storage device, as disclosed in patent application CN214546838U, includes a shell, which is a hollow cylindrical shell with a sealing cap on the upper side. The hollow cylindrical shell has a liquid inlet and an outlet below the inlet. An internal support assembly allows sample slides of different sizes to be placed in different storage compartments, accommodating multiple slides of different sizes simultaneously. Removal from the top avoids contact with other sample slides, facilitating easy retrieval. A rotating shaft, through the cooperation of a connecting block and a mounting groove, allows the desired sample slide to be accurately rotated to the sampling port position by manually rotating the handle. Then, by rotating the movable cover, the desired sample slide can be accurately removed into the sliding groove, minimizing contact between other sample slides and the external environment.

[0004] However, the structure of this utility model makes it difficult to distinguish and store different samples, and its application scope is relatively limited. Therefore, we propose a biological sample storage device that solves the problem of the utility model's difficulty in distinguishing and storing different types of sample materials, improves the utility model's practical effect, and expands its application scope.
