[0039] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0041] Rewarming is a necessary procedure for restoring the activity of cryopreserved cell tissues. The activity of cell tissues after rewarming will directly affect their downstream usage. In the related art, an artificial water bath is used to rewarm multiple tubes 6 containing cell tissues. Although this rewarming method is simple to operate, the number of tubes that can be rewarmed at one time is limited. In addition, since a handheld rewarming method is generally used, the control of the rewarming process depends entirely on the experience of the operator. Therefore, there will be large differences in the rewarmed tubes on different batches of trays, which are difficult to standardize. For a large number of tubes 6 that need to reach different target temperatures, the labor cycle of the artificial water bath operation is long, and there is a certain degree of difficulty in accurately controlling the rewarming rate.

[0042] The multiple tubes radially distributed on the rack have the same angular velocity of rotation of the rack, which results in the linear velocity of the tubes outside the rack being higher than the linear velocity of the tubes inside the rack. The rate of heat exchange between the tubes outside the rack and the water in the heating zone is significantly higher than that of the tubes inside the rack. If the same heating zone heats and reheats the multiple tubes radially distributed on the rack, it is easy for the outer tubes to reach the target reheating temperature while the inner tubes are not completely thawed in the same time, and it is difficult for the multiple tubes 6 of the same batch to reach the preset target reheating temperature at the same time.

[0043] Based on this, the embodiment of the present disclosure provides a rewarming device. Figure 1 It is a schematic diagram of the three-dimensional structure of the rewarming device according to an embodiment of the present disclosure; Figure 2 It is a schematic diagram of the three-dimensional structure of the heating tank 2 according to the embodiment of the present disclosure; Figure 3 It is a three-dimensional structural schematic diagram of a lifting assembly 3 according to an embodiment of the present disclosure; Figure 4 It is a schematic diagram of the three-dimensional structure of the lifting assembly 3 according to another embodiment of the present disclosure; Figure 5 It is a schematic diagram of the three-dimensional structure of the rewarming device according to the embodiment of the present disclosure at another angle; Figure 6 This is a schematic diagram of the three-dimensional structure of the rewarming device according to the embodiment of the present disclosure at another angle. The rewarming device is described in detail below through a specific embodiment:

[0044] Reference Figures 1 to 6 As shown, this embodiment provides a rewarming device, including a disc rack 1 having multiple placement areas in the radial direction, and a heating tank 2 having multiple heating areas in the radial direction. The multiple placement areas are arranged in a one-to-one correspondence with the multiple heating areas, so that different placement areas can be heated in different heating areas. The lifting component 3 is detachably connected to the disc rack 1 and drives the disc rack 1 to lift and lower along the first direction X to detach from / enter the accommodating cavity. At least one of the lifting component 3 and the disc rack 1 is connected to the rotating component to drive the disc rack to rotate. At least one of the lifting component 3 and the disc rack 1 is connected to the rotating component. After the disc rack 1 enters the heating tank 2, it can rotate and be heated. After the tube body 6 placed on the disc rack 1 and the medium (such as water) in the heating area have a relative speed, the heat exchange efficiency is better. And when the disc rack 1 rotates, the tube body 6 oscillates with the tube body 6 so that the cell tissue inside it is heated more evenly. The consistent angular velocity of the disk rack rotation causes the linear velocity of the tube body located on the outside of the disk rack to be higher than the linear velocity of the tube body located on the inside of the disk rack. The rate of heat exchange between the tube body located on the outside of the disk rack and the water in the heating zone is significantly higher than that of the tube body located on the inside of the disk rack. Multiple placement areas are arranged in a one-to-one correspondence with multiple heating zones. The temperature of the heating zone corresponding to the tube body located on the outside of the disk rack is lower than that of the heating zone corresponding to the tube body located on the inside of the disk rack. The target thawing effect can be achieved by placing the disk rack in the heating tank for heating and reheating within the same time period.

[0045] The orthographic projection shapes of the disc rack 1 and the heating tank 2 in the first direction X include, but are not limited to, circular, elliptical and polygonal, and the multiple placement areas are distributed at intervals along the radial direction. The heating tank 2 includes an open accommodating cavity formed by a wall portion, and the orthographic projection of the disc rack 1 in the first direction X is located within the orthographic projection of the heating tank 2 in the first direction X, so that after the disc rack 1 enters the heating tank 2, all the tubes 6 placed on the disc rack 1 can enter the heating tank 2 for heating and temperature rise. The first direction X is arranged to intersect with the radial direction, and illustratively, the first direction X is arranged to intersect with the radial direction perpendicularly. The disc rack 1 is driven to rise and fall along the first direction X to detach from / enter the heating tank 2 by setting a lifting component 3, and the disc rack 1 is replaced when detaching from the heating tank 2 to heat multiple batches of tubes 6.

[0046] Of course, if the tubes of the same batch on the rack need to be reheated to different target temperatures, the reheating device provided in this embodiment has a heating slot 2 with multiple heating zones in the radial direction, and the multiple placement zones are arranged in a one-to-one correspondence with the multiple heating zones, so that different placement zones can be heated in different heating zones. The reheating device is simple to operate and can perform multi-target temperature reheating operations on the tubes 6 of the same batch on the rack 1, saving time and effort.

[0047] In some embodiments, the disk rack 1 includes a disk body, and the disk body is provided with a plurality of through holes, and the through holes are used to clamp the tube body 6, and each placement area includes a plurality of through holes distributed along the circumference. The through holes located on the circumference of the same radius are a through hole group, and a temperature heating zone corresponds to at least one through hole group. Such a configuration makes the disk rack 1 simple in structure and convenient for distinguishing tube bodies 6 with different target temperatures.

[0048] In some embodiments, the heating tank 2 includes at least one annular plate 21, and the annular plate 21 is extended along the first direction X. At least one annular plate 21 divides the accommodating cavity into a plurality of heating zones distributed radially. The heating zones can be used to fill the fluid medium (such as water), and a heating body 22 is provided in each of the heating zones. The heating body 22 can be a heating coil provided on the bottom wall of the accommodating cavity, or can be a heating element such as a heating rod provided in each heating zone. The heating power of the heating body 22 in each of the heating zones is different so that the multiple heating zones on the same tray 1 can reach different target temperatures within the same heating time. A liquid inlet 24 and a liquid outlet are also provided on the wall of the heating tank 2 to facilitate the replacement or replenishment of the fluid medium.

[0049] In some embodiments, each heating zone is provided with a temperature detection sensor 23. The temperature detection sensor 23 can timely and accurately feedback the heating temperature of the corresponding heating zone, so that the reheating accuracy is higher. Exemplarily, the temperature detection sensor 23 is connected to the annular plate 21.

[0050] The heating zone heats the corresponding tube body 6, and the temperature of the fluid medium in the heating zone is fed back in real time through the temperature detection sensor 23 in the heating zone until the temperature of the fluid medium reaches the target temperature.

[0051] In some embodiments, the lifting assembly 3 includes a first driving member and a lifting rod 31 connected to the first driving member, the lifting rod 31 has a connecting portion, and the connecting portion is detachably connected to the disc rack 1. And / or: the lifting rod 31 and the first driving member are embedded in the wall portion. Specifically, a hollow mounting column can be formed at the center of the bottom wall of the wall portion along the first direction X toward the disc rack 1, and the lifting rod 31 and the first driving member are arranged in the hollow mounting column. The first driving member includes any one of a telescopic cylinder, a telescopic rod and a linear module. The first driving member drives the lifting rod 31 to rise and fall along the first direction X. A locking portion 311 is provided at the connection between the connecting portion and the disc rack 1. For example, a through hole is provided in the center of the disc rack 1, and the central part of the connecting portion is partially protruded to form a connecting shaft, and an external thread is provided on the connecting shaft so that the connecting shaft can be inserted into the through hole and then threadedly connected with the locking nut.

[0052] In some feasible embodiments, the rotating assembly includes a first driving motor, which is connected to the lifting rod 31 to drive the lifting rod 31 to rotate. After the disc rack 1 enters the heating tank 2, it can rotate and be heated. After the tube body 6 placed on the disc rack 1 and the medium (such as water) in the heating zone have a relative speed, a better forced convection heat exchange effect is achieved. And when the disc rack 1 rotates, the tube body 6 oscillates with the tube body 6 so that the cell tissue inside it is heated more evenly. The output shaft of the first driving motor can be connected to the first driving member, or the output shaft of the first driving motor is connected to the connecting part.

[0053] In some embodiments, the lifting assembly 3 includes a second driving member, a lifting platform 32, a slide rail 33 arranged along the first direction X, and a slider 34 connected to the lifting platform 32, and the slider 34 is slidably connected with the slide rail 33. The second driving member includes a rack 35, a gear 36 connected to the rack 35, and a second driving motor 37 connected to the gear 36. Any of the rack 35 and the gear 36 is connected to the lifting platform 32, and a reducer may be connected between the second driving motor 37 and the gear 36. The lifting platform 32 is detachably connected to the rack 1. Two sliders 34 may be provided, and the sliders 34 have opposite connecting ends and sliding ends that cooperate with the slide rail 33. Both sides of the lifting platform 32 are connected to the connecting end of a slider 34, and the connection methods include but are not limited to welding, injection molding, bonding, and fastener connection. The sliding end of each slider 34 may be slidably connected to at least one slide rail 33.

[0054] In some embodiments, the rewarming device further comprises a box 4, and the heating tank 2, the tray 1 and the lifting assembly 3 are all arranged in the box 4. The above-mentioned slide rails 33 are all connected to the box 4. Exemplarily, the box 4 has two opposite side walls, and the two side walls are a sandwich structure. The sandwich structure includes an outer plate 41 and an inner plate 42 stacked, and a cavity is formed between the outer plate 41 and the inner plate 42. The slide rail 33 is located in the cavity, and the height of the inner plate 42 is lower than the height of the outer plate 41. The height difference between the inner plate 42 and the outer plate 41 is the movable stroke of the slider 34 along the first direction X. Further, the edge of the inner plate 42 extends radially to form a limit portion 43. When the slider 34 drives the lifting platform 32 to descend to the lowest position, the limit portion 43 limits the lifting platform 32. The lowest position can be that the tube body 6 on the tray 1 completely enters the heating zone. If it continues to move downward, it will collide with the bottom of the heating tank 2 and damage the tube body 6. The output shaft of the second drive motor 37 is connected to the gear 36 to drive the gear 36 to rotate. As an implementable embodiment, the mounting base of the second drive motor 37 is connected to the lifting platform 32, the rack 35 is connected to the outer plate 41, the second drive motor 37 drives the gear 36 to rotate, and the gear 36 moves along the first direction X under the force of the rack 35. As another implementable embodiment, the mounting base of the second drive motor 37 is connected to the outer plate 41, and the rack 35 is connected to the lifting platform 32 (or the connecting end of the slider 34). The gear 36 and the rack 35 are located on the same side of the slider 34, so the output shaft of the motor passes through the slider 34 and is connected to the gear 36.

[0055] In some feasible embodiments, the bottom plate 44 of the box body 4, the two side walls, the front plate 45 and the top plate are combined to form a structure having a closed cavity. The bottom plate 44 of the box body 4 has a certain thickness, and one side of the bottom plate 44 close to the closed cavity is recessed along the first direction X away from the closed cavity to form a heating groove 2 with a concave structure.

[0056] In some embodiments, the rotating assembly is connected between the lifting platform 32 and the disk rack 1, and the rotating assembly includes a third drive motor 38 and a rotating shaft 39, one end of the rotating shaft 39 is connected to the third drive motor 38, and the other end of the rotating shaft 39 is detachably connected to the disk rack 1. The detachable connection method between the rotating shaft 39 and the disk rack 1 includes but is not limited to a snap-on type, a pin type, and a magnetic type. Specifically, along the first direction X, the load-bearing frame 301 is located below the lifting platform 32, and the load-bearing frame 301 includes a load-bearing plate and a plurality of connecting rods, and the connecting rods are connected between the lifting platform 32 and the load-bearing plate. The second drive motor 37 is arranged on the load-bearing plate, and a through hole is provided in the middle of the load-bearing plate. The output shaft of the second drive motor 37 is connected to the rotating shaft 39, and the output shaft of the second drive motor 37 and the middle part of the rotating shaft 39 are located in the through hole. A bearing is provided between the part located in the through hole and the wall of the through hole, and the bearing can be a thrust bearing. Further, the output shaft of the second drive motor 37 is connected to the rotating shaft 39 through a coupling. To make the connection more stable during the entire transmission process.

[0057] In addition, in some embodiments, the front plate 45 of the box body 4 is further provided with an opening and a door plate 451 connected to the opening, and the shape and size of the opening are adapted to the disk rack 1 to facilitate replacement of the disk rack 1, and of course also include a space for operators to manually remove or install the disk rack 1. Exemplarily, the door plate 451 is rotatably connected to a portion of the edge of the opening, and a limiting member 452 is connected between the door plate 451 and the inner wall of the box body 4 to limit the opening and closing angle of the door plate 451, and the limiting member 452 can be two hinged connecting rods.

[0058] A control panel 5 may also be provided on the front plate 45 of the box body 4. The control panel 5 is embedded in the front plate 45. The structure of the control panel 5 has an interactive operation module. The lifting assembly 3, the temperature detection sensor 23, the heating body 22 and the interactive operation module are all coupled to the controller. There are multiple rewarming programs in the interactive operation module, and each rewarming program has a corresponding heating time and heating power of the heating body 22. Of course, in order to remind the operator, a prompt component, such as a buzzer or an indicator light, may also be installed on the box body 4, and the prompt component is coupled to the controller.

[0059] The rewarming device provided in this embodiment first selects the corresponding rewarming program in the interactive operation module of the device for the frozen samples to be rewarmed. The power of the corresponding heating body 22 is further controlled according to the real-time temperature feedback from the temperature detection sensor 23 in each heating zone to further satisfy that the water (or other medium) in each heating zone can reach the temperature preset by the program within the same time. The purpose of standardizing the rewarming operation, making the rewarming process more efficient, and improving the quality of rewarming is achieved. The standardization of the rewarming operation means that different batches can achieve rewarming consistency. The efficiency of the rewarming process is reflected in the high number of tubes that can be rewarmed at one time. The quality of rewarming is reflected in the use of a program to control the rewarming process, which can optimize the rewarming process.

[0060] When the rewarming device provided in this embodiment is used, the door panel 451 is opened, the rewarming rack 1 is disassembled, and the cryopreserved tube 6 taken out from the low-temperature refrigeration equipment or the liquid nitrogen dewar is quickly placed on the rack 1, and then the rack 1 with the tube 6 is installed on the lifting assembly 3 (or connected to the lifting assembly 3 through the rotating assembly), and the door panel 451 is closed. The lifting assembly 3 drives the rack 1 to move toward the heating tank 2 along the first direction X until the tube 6 enters the heating tank 2, and the multiple heating zones in the heating tank 2 heat and rewarm the corresponding tube 6 that enters. When the tube 6 is rewarmed, the lifting assembly 3 drives the rack 1 to move away from the heating tank 2 along the first direction X until the tube 6 is out of the heating tank 2. In this process, when the tube 6 is located in the heating tank 2, the rotating assembly directly or indirectly drives the rack 1 to rotate.
