Description
Technical Field
[0001] The utility model belongs to the technical field of cell resuscitation devices, and in particular relates to a stem cell resuscitation device. Background Art
[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.
[0003] The long-term storage of stem cells is achieved by using deep cryogenics (liquid nitrogen). They remain dormant during prolonged refrigeration, so they must be revived for subsequent use to restore their activity. Cell resuscitation involves thawing cells frozen in -196°C liquid nitrogen to 37°C. The thawing process requires constant temperature and rapid operation, allowing cells to quickly pass through the -5°C to 0°C range, where they are most vulnerable, to prevent ice crystals from re-crystallizing and causing damage to the cells, leading to cell death.
[0004] In the prior art, the commonly used cell recovery method is to place the cryopreservation tube in a water bath preheated to 37°C, and shake it quickly to quickly thaw the cell freezing solution in the cryopreservation tube. However, when manually recovering cells, in order to ensure that the cell freezing solution is fully and quickly melted in the water bath, it is impossible to complete the recovery of multiple cells at a time, which has low work efficiency and will cause arm fatigue to the relevant personnel. In addition, due to individual operational differences, such as inconsistent cell shaking frequency and amplitude, it is impossible to guarantee consistent recovery time for each tube of cells, which may affect the viability and quality of the cells and lead to differences between recovered cells. In addition, during recovery, the cell cryopreservation tube needs to be completely immersed in the water bath, which poses a certain risk of contamination. Therefore, this method is not suitable for large-scale stem cell recovery. Utility Model Content

[0029] In a typical embodiment of the present invention, Figure 1 and Figure 2As shown, a stem cell resuscitation device is provided, including a fixed structure 1, a driving component 2, a connecting component 3 and a cryotube placement tray 4; the fixed structure 1 is fixedly connected to a water bath 5, the driving component 2 is installed on the fixed structure 1, the driving component 2 is connected to the connecting component 3, the connecting component 3 is connected to the cryotube placement tray 4, the driving component 2 drives the cryotube placement tray 4 to rotate through the connecting component 3, and a plurality of cryotube jacks 41 are provided on the cryotube placement tray 4.
[0030] In this embodiment, the fixed structure 1 includes a main frame 11 and multiple fixed frames 12. The main frame 11 is a circular, downward-opening cylindrical structure. The fixed frames 12 are telescopic rods, and the multiple fixed frames 12 are evenly connected to the sides of the main frame 11. In a specific implementation of this embodiment, four fixed frames 12 are provided, connected to the main frame in a "cross" shape. The fixed frames 12 can be extended within a certain range to accommodate different models of water baths.
[0031] Furthermore, a magnet 13 is provided at one end of the fixing bracket 12 away from the main bracket 11. The magnet 13 and the water bath 5 are attracted to each other by magnetic force, thereby fixing the entire device to the water bath 5. In a specific implementation of this embodiment, the magnet 13 has an arc-shaped structure, and the curvature of the inner arc of the magnet matches the curvature of the outer wall of the fixing bracket 12. When the fixing bracket 12 is retracted, the magnet 13 can be attached to the main bracket 11, thereby reducing the space occupied by the entire device.
[0032] In this embodiment, the driving assembly 2 includes a driving motor 21, the output shaft of the driving motor 21 is connected to the first gear 22, the driving motor 21 is fixedly mounted on the inner wall surface of the main bracket 11, and the driving motor is powered by a built-in power supply.
[0033] In this embodiment, the connecting assembly 3 includes a connecting rod 31, one end of which is rotatably connected to the center position of the main bracket 11 through a bearing, and the other end of the connecting rod 31 is connected to the fixing rod 33. The end of the fixing rod 33 is fixedly connected to the center of the cryotube placement tray 4. The diameter of the cryotube socket 41 on the cryotube placement tray 4 matches the diameter of the cryotube so that the cryotube can be inserted into the cryotube socket 41 for fixing.
[0034] Furthermore, a second gear 23 is fixedly installed on the connecting rod 31 near the main frame 11, and the second gear 23 is engaged with the first gear 22, and the power of the drive motor 21 is transmitted to the connecting component 3 and the cryotube placement tray 4 through the first gear 22 and the second gear 22.
[0035] Furthermore, two cryotube bag clamps 32 are fixedly connected to the connecting rod to seal the opening of the cryotube bag. The cryotube bag clamps 32 are composed of two horizontally placed magnets, the outer surfaces of which are encapsulated in plastic. The cryotube bag is secured with a PE glove. During use, the cryotube is placed between the fingers of the PE glove to prevent water from entering the cryotube and contaminating the cells. The top of the glove is then clamped and secured with the two magnets of the cryotube bag clamps 32.
[0036] In this embodiment, the connecting rod 31 and the fixing rod 33 are both retractable rods, and the diameter of the cryotube placement tray 4 is smaller than the inner diameter of the circular main body bracket 11.

[0038] Stretch the fixing bracket 12 so that the magnet 13 at the end of the fixing bracket 12 can be adsorbed on the top of the water bath 5, place the cryotube in the finger of the PE glove, and insert the cryotube covered with the PE glove into the cryotube insertion hole 41 of the cryotube placement tray 4, then clamp the top of the glove with the two magnets of the cryotube bag fixing clamp 32, and stretch the connecting rod 31 at the same time to ensure that the cryotube placement tray is close to the water bath liquid surface, that is, by placing multiple cryotubes on the placement tray into the water bath at the same time, and it is necessary to keep the solution in the cryotube completely below the water bath liquid surface.
[0039] The drive motor 21 is energized, and the output shaft of the drive motor 21 drives the first gear 22 to rotate. Since the first gear 22 is engaged with the second gear 23 and the second gear is fixedly connected to the connecting rod 31, the first gear 22 drives the connecting assembly 3 and the cryotube placement tray 4 to rotate, so that the multiple cryotubes immersed in warm water on the cryotube placement tray are continuously rotated, so that the cryotubes are heated evenly, the rewarming efficiency is improved, and the problem of arm fatigue of the personnel is avoided.
[0040] After use, the fixing bracket 12 , the connecting rod 31 and the fixing rod 33 can be retracted to complete the storage of the device, and the device can be adsorbed and fixed on the side wall of the water bath 5 by the magnet 13 .
