Description

Technical Field

[0001] The utility model relates to the technical field related to biological cell storage cabinets, in particular to a biological cell storage cabinet. Background Art

[0002] The principle of biological cell storage is mainly to reduce the metabolic activity of cells through a low-temperature environment, thereby extending the storage time of cells. Cell storage usually involves storing healthy, active cells in a low-temperature environment to maintain their maximum activity, and then taking them out for use when needed in the future. This method can be used for the purpose of treating diseases, health care, anti-aging, improving sub-health, etc. The specific operating steps of cell storage include placing the cells in a low-temperature environment, usually in liquid nitrogen at -196°C, so a storage cabinet is required for storage.

[0003] Publication No.: CN219352884U proposes a biological cell storage cabinet, comprising a cabinet body, a storage mechanism installed inside the cabinet body, a fixing mechanism installed at the bottom of the cabinet body, the storage mechanism including a protective plate, a top cover movably installed on the top of the cabinet body and located on the top of the protective plate, a plurality of placement slots are opened through the top of the protective plate, a buffer plate is installed at the bottom of the cabinet body, a plurality of fixing slots are opened through the top of the buffer plate, a placement rack is placed and installed between the placement slots and the fixing slots, a handle is installed on the top of the placement rack, a plurality of partitions are installed inside the placement rack, and a storage board is placed and installed on the top of the partition; the biological cell storage cabinet described in the utility model is convenient for taking and placing cells, helps to reduce the leakage of liquid nitrogen inside the cabinet body, and is convenient for supporting and fixing the cabinet body, and is convenient for moving and transporting.

A support block 4 is installed at the upper end of the interior of the cabinet body 1. The baffle 3 is placed inside the cabinet body 1, and the bottom is in contact with the top of the support block 4. A placement hole that matches the size of the baffle 3 is opened on the top of the cabinet body 1. The support block 4 plays a role in supporting the limit baffle 3. The baffle 3 can be removed as a whole, which is convenient for subsequent staff to clean the interior of the cabinet body 1. The top of the cabinet body 1 is hinged with a cabinet cover 2 that matches the size of the placement hole. The cabinet cover 2 and the cabinet body 1 are an integrated structure, and the cabinet cover 2 and the cabinet body 1 are sealed. The bottom of the cabinet body 1 is equipped with four universal wheels, two of which are lockable universal wheels, which are convenient for the overall movement and fixation of the cabinet body 1.

[0028] The scoop 7 is located at both ends of the bottom of the cabinet 1. A connecting rod 8 is installed on the top of the scoop 7. Openings that are adapted to the size of the scoop 7 are opened at both ends of the baffle 3. There is a gap between the baffle 3 and the top of the cabinet 1. The top of the connecting rod 8 extends out of the opening and is flush with the top of the cabinet 1. The gap serves to facilitate the staff to take the connecting rod 8 and the storage frame 6. Both ends of the top of the baffle 3 are hinged with a cover plate 9. The end of the cover plate 9 away from the hinge point is fitted with the connecting rod 8, and the gap between the connecting rod 8 and the opening is closed by the cover plate 9. To prevent liquid nitrogen from leaking from the opening, an observation hole is provided on the top of the cover plate 9. During implementation, a smooth wooden stick is required. The observation hole is adapted to the size of the wooden stick. By placing the wooden stick into the observation hole, the wooden stick is fully immersed in the liquid nitrogen of the scoop 7. After waiting for 10 to 15 seconds, it is taken out and the liquid nitrogen level is obtained by observing the frosted length of the wooden stick. Liquid nitrogen is added in time. The top of the cover plate 9 is hinged with an end cap 10 adapted to the size of the observation hole. The observation hole is closed by the end cap 10 to prevent liquid nitrogen from leaking from the observation hole.

[0029] A base 5 is installed at the center of the bottom of the cabinet 1, and multiple storage frames 6 are placed on the top of the base 5. The base 5 is composed of convex blocks installed at the four corners of the bottom of the board. The board does not contact the cabinet 1. The convex blocks are used to support the board. The contact area between the board and the cabinet 1 is reduced by the convex blocks to prevent the liquid nitrogen from flowing inside the cabinet 1 and being blocked by the base 5. Through holes are provided on both sides of the storage frame 6. A back plate 12 is installed in the through hole on one side. Multiple bottom plates 13 are equidistantly installed inside the storage frame 6. One side of the bottom plate 13 is in contact with the back plate 12, and the back plate 12 serves to seal the bottom plate 13. The function of the side through hole is to prevent the cell culture plate 14 from falling from the through hole on one side. The other side of the bottom plate 13 is located in the through hole on the other side. The cell culture plate 14 is placed on the top of the bottom plate 13. The insertion rod 15 is slidably connected to the through hole on the other side and located on the top of the bottom plate 13. A plurality of air holes are provided at the bottom of the bottom plate 13. A plurality of connecting holes are also provided at both ends of the storage frame 6. The connecting holes correspond to the position of the bottom plate 13. A plurality of jacks that are adapted to the size of the storage frame 6 are provided on the top of the baffle 3.

[0030] In this embodiment, specifically: a plurality of slide bars 11 are installed on the top of the base 5, and slide grooves slidably connected to the slide bars 11 are provided at both ends of the storage frame 6. The top of the slide bar 11 fits with the bottom of the baffle 3. The slide bar 11 and the slide groove increase the stability of the storage frame 6 sliding up and down, making it convenient to take and place the storage frame 6. A channel adapted to the size of the insertion rod 15 is provided between the through hole and the slide groove on the other side. Both ends of the insertion rod 15 slide and fit with the slide bar 11. When the storage frame 6 is located between the slide bars 11, the insertion rod 15 is limited by the slide bar 11, and moving the cabinet 1 will not cause the insertion rod 15 to slip off. When the insertion rod 15 is located in the through hole and the slide groove on the other side, it fits with the cell culture plate 14, thereby fixing the cell culture plate 14.

[0031] Working principle: when in use, the staff opens the cabinet cover 2, then rotates the cover plate 9 to open the openings at both ends of the baffle 3, and then moves the connecting rod 8 upward to drive the spoon 7 close to the opening of the baffle 3, and adds liquid nitrogen from the opening to the spoon 7. After adding, move the connecting rod 8 downward to make the spoon 7 fit with the bottom of the cabinet 1, and then rotate the cover plate 9 in the opposite direction to close the openings at both ends of the baffle 3, and then close the cabinet cover 2. The inside of the cabinet 1 is cooled by liquid nitrogen. When it is necessary to measure the liquid nitrogen level, open the cabinet cover 2, rotate the end cover 10 to open the observation hole of the cover plate 9, and then Insert the external wooden stick into the observation hole of the cover plate 9 so that the stick is fully immersed in the liquid nitrogen of the scoop 7. Wait for 10 to 15 seconds before taking it out. The liquid nitrogen level is obtained by observing the frost length of the wooden stick, and liquid nitrogen is added in time. When taking or placing the cell culture plate 14, open the cabinet cover 2, slide the storage frame 6 upward, remove the storage frame 6 from the insertion hole of the baffle 3, and then slide the insertion rod 15 corresponding to the cell culture plate 14 horizontally to release the restriction on the single cell culture plate 14. The single cell culture plate 14 can be taken or placed through the through hole on the other side of the storage frame 6.
