Description

Technical Field

[0001] This utility model relates to the technical field of cell cryopreservation programmed cooling devices, and in particular to a cell cryopreservation programmed cooling device. Background Technology

[0002] Cell cryopreservation refers to the technique of suspending cells in a cryoprotectant and then slowly or rapidly cooling them to extremely low temperatures through a specific cooling process, thereby bringing the cells' metabolism and growth activities to a near standstill and preserving their activity and function for a long period of time.

[0003] Existing cell cryopreservation uses cryopreservation machines, but the temporary storage boxes inside these machines have limited functionality. If cell culture dishes are placed inside for cryopreservation, they cannot be properly restrained. Consequently, when the storage box is moved, the culture dishes inside may slide. Since the inside of the storage box is relatively smooth, the culture dishes may hit the inner wall of the storage box heavily, potentially causing damage to the culture dishes and contamination of the frozen cells. To address this, we provide a cell cryopreservation programmed cooling device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing cell cryopreservation machines, such as the lack of limiting functions in the temporary storage tank, and to provide a cell cryopreservation cooling device.

[0006] In a preferred embodiment, the two ends of the first spring are fixedly connected to the outer surfaces of the bonding plate and the moving plate, respectively, and the two ends of the second spring are fixedly connected to the outer surface of the limiting ring and the inner wall of the connecting block, respectively.

[0007] In a preferred embodiment, one end of the lever is provided with a pull block, which is fixedly connected to the lever.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention, through the inclusion of a barrier mechanism, allows the cell cryopreservation machine's temporary storage box to effectively contain and limit the cell culture dishes inside, preventing them from colliding with the inner wall of the storage box. A bonding plate is also included, which adheres to the culture dishes, preventing them from sliding when the storage box is pulled.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1-6 As shown, this utility model provides a technical solution: a cell cryopreservation programmed cooling device, comprising: a cryopreservation machine 1, the cryopreservation machine 1 having an internal barrier mechanism 2, the barrier mechanism 2 including a temporary storage box 21, a movable plate 22 sleeved inside the temporary storage box 21, the movable plate 22 being slidably connected to the temporary storage box 21, a bonding plate 23 being provided on one side of the movable plate 22, a spring 24 being provided on one side of the bonding plate 23, a connecting block 25 being fixedly connected to the top of the movable plate 22, and a locking rod 26 sleeved inside the temporary storage box 21 and the connecting block 25, the locking rod 26 being connected to the temporary storage box 21 and the connecting block. All 25 are slidably connected. The temporary storage box 21 has a locking hole inside that matches the locking rod 26. A limiting ring 27 is sleeved on the outer surface of the locking rod 26. The limiting ring 27 is fixedly connected to the locking rod 26. A second spring 28 is sleeved on the outer surface of the locking rod 26. An auxiliary mechanism 3 is provided at the bottom of the temporary storage box 21. The two ends of the first spring 24 are fixedly connected to the outer surfaces of the bonding plate 23 and the moving plate 22, respectively. The two ends of the second spring 28 are fixedly connected to the outer surface of the limiting ring 27 and the inner wall of the connecting block 25, respectively. A pull block 29 is provided at one end of the locking rod 26. The pull block 29 is fixedly connected to the locking rod 26.

[0026] In this embodiment, a movable plate 22 is provided and sleeved inside the temporary storage box 21, thereby driving the other components of the blocking mechanism 2 to move. A bonding plate 23 is provided and can be in a bonding state with the culture dish inside the temporary storage box 21, thereby blocking the culture dish. At the same time, a spring 24 is provided, and the spring 24 can generate elastic force when compressed, thereby the spring 24 can rebound the bonding plate 23. Thus, the setting of the spring 24 ensures that the bonding plate 23 can still be in contact with the culture dish after the movable plate 22 is fixed in position. A locking rod 26 is provided and can be locked into the interior of the temporary storage box 21, thereby the locking rod 26 can maintain the stability of the movable plate 22, so that the cell culture dish inside the temporary storage box 21 will not slide or move when it is pulled out.

[0027] Example 2

[0028] like Figures 1-6 As shown, the auxiliary mechanism 3 includes a fixed frame 31, which is fixedly connected to the cryopreservation machine 1. A slider 32 is sleeved inside the fixed frame 31 and is slidably connected to the fixed frame 31. A connecting rod 33 is provided on the top of the slider 32 and is fixedly connected to the slider 32. A slider 34 is sleeved inside the connecting rod 33 and is slidably connected to the connecting rod 33. The slider 34 is fixedly connected to the temporary storage box 21.

[0029] In this embodiment, by setting a fixed frame 31 and a slider 32, with the slider 32 slidably connected to the fixed frame 31, the connecting rod 33, which is fixedly connected to the slider 32, can slide, thereby allowing the barrier mechanism 2 to be pulled out from inside the cryostat 1. A second slider 34 is also set, and the second slider 34 can slide inside the connecting rod 33, thereby allowing the second slider 34 and the connecting rod 33 to completely remove the barrier mechanism 2 from inside the cryostat 1, so that the culture dishes inside the temporary storage box 21 can be easily organized and located.

[0030] Working principle:

[0031] like Figures 1-6As shown, in use, the temporary storage box 21 can be pulled out from inside the cryopreservation machine 1. Pulling the temporary storage box 21 causes the slider 24 to slide inside the connecting rod 33. When the slider 24 can no longer slide inside the connecting rod 33, the connecting rod 33 will cause the slider 1 32 to slide inside the fixing frame 31, thus allowing more of the temporary storage box 21 to be pulled out. Then, a certain number of culture dishes are arranged inside the temporary storage box 21. Next, the pull block 29 is pulled, causing the locking rod 26 to slide. When the locking rod 26 slides, the limiting ring 27 compresses the spring 28, causing the spring 28 to generate elasticity. At this point, the moving plate 22 is slid, which causes the bonding plate 23 to move closer and closer to the culture dish until the bonding plate 23 contacts the culture dish. The bonding plate 23 compresses the spring 24, causing the spring 24 to generate elastic force. At this point, the connecting block 25 is moved to a suitable position so that the locking rod 26 can be reset and locked into the interior of the temporary storage box 21. Then, the moving plate 22 is kept stable, and the pull block 29 is released. The elastic force of the spring 28 is released instantly, and the locking rod 26 is reset, so that the locking rod 26 is locked into the interior of the temporary storage box 21. At this point, the blocking mechanism 2 can limit the culture dish, so that the culture dish will not slide when the temporary storage box 21 is pulled.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
