Description

Technical Field

[0001] This utility model relates to the field of insulated boxes, specifically an insulated box for the low-temperature transport of cell samples. Background Technology

[0002] Stem cell research and clinical application is a systematic undertaking requiring coordination among multiple disciplines, institutions, and departments. Currently, stem cell culture technology is becoming increasingly mature, and stem cell applications are being widely implemented. Stem cell clinical research and treatment require independent cell preparation units to provide cells, and to ensure these cells reach optimal viability for both research and clinical application, standardized cell storage and transportation procedures are necessary. Currently, due to the influence of stem cell bioactivity, stem cells cannot maintain optimal cell viability for extended periods, nor can they be guaranteed to be stored at a suitable temperature for long periods. Furthermore, some medical devices need to be carried during stem cell transportation.

[0003] A cell cryogenic transport box, such as one disclosed in announcement number CN210671850U, includes an insulated box comprising a body and a lid. The body contains a cell product placement slot, and the lid is sealed onto this slot. A rubber pad matching the size of the slot bottom is laid on the bottom of the slot. Circular placement slots are distributed at one end of the rubber pad, while elongated placement slots are distributed at the remaining positions. A partition is provided between the circular and elongated placement slots, and the partition is snapped onto the inner wall of the placement slot. By embedding and fixing tube-packaged and bagged cell products respectively in the circular and elongated placement slots, and separating them with the partition, the fixed tube-packaged and bagged cell products are prevented from shaking and colliding. The rubber pad provides good cushioning, offering good fixation and protection. The partition is detachable and can be installed inside the box, allowing for efficient use of the internal space.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that the device, which relies solely on the closure of the box to keep the cell samples warm during cell sample transportation, may not be able to maintain a constant low temperature inside the box. This could lead to significant temperature differences inside the box during transportation, which could result in cell death, damage, or loss of activity.

[0005] Therefore, a cell sample cryogenic transport insulated box is proposed to address the above problems. Utility Model Content

[0013] Preferably, handles are fixedly installed on the top of both the left and right sides of the insulated outer box, and self-locking casters are fixedly installed at the four corners of the bottom of the insulated outer box.

[0014] The beneficial effects of this utility model are:

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 By combining the outer insulated box 1, the inner insulated box 2, the insulation pad 3, the placement box 5, the exhaust hole 6, the diffusion frame 7, and the placement rack 8, the function of low-temperature storage of cell samples is realized. Thus, by storing low-temperature cooling media, cooling gas can be provided to the cell sample storage space in real time, thereby reducing the impact of external environmental temperature on cell samples. At the same time, the double insulated box further improves the insulation effect of low-temperature transportation.

[0028] The top of the placement rack 8 has several placement holes 9 on one side, and a slot 10 is provided on the top of the placement rack 8. An isolation plate 11 is movably installed inside the slot 10, and a T-shaped block 12 is fixedly installed at the bottom of the isolation plate 11.

[0029] Reference Figure 4 and Figure 5 The placement hole 9 and the isolation plate 11 facilitate the positioning of different cell sample storage containers, thereby increasing the applicability of the incubator. The slot 10 and the T-shaped block 12 facilitate the positioning of the isolation plate 11, thereby ensuring the stability of the isolation plate 11 during movement.

[0030] A first sealing ring 13 is fixedly installed on the top of the insulated inner box 2. Positioning seats 14 are fixedly installed on the top of both sides of the insulated inner box 2. Limiting rods 15 are fixedly installed inside the positioning seats 14. A box cover 16 is sleeved on the surface of the limiting rods 15.

[0031] Reference Figure 1 and Figure 5 The first sealing ring 13 facilitates the sealing of the contact surface between the lid 16 and the inner insulated box 2, thereby effectively preventing the cold air from leaking out of the inner insulated box 2, thus ensuring the long-term stability of the internal temperature of the inner insulated box 2 and achieving the purpose of improving the insulation effect. The lid 16 facilitates the closure of the top opening of the inner insulated box, preventing foreign objects from entering the inner insulated box 2.

[0032] A shock-absorbing pad 17 is fixedly installed on the inner wall of the bottom of the insulated outer box 1. Several sleeves 18 are fixedly installed on the inner walls of the four sides of the insulated outer box 1. Springs 19 are movably installed inside the sleeves 18.

[0033] Reference Figure 2 The shock-absorbing pad 17 facilitates contact with the bottom surface of the inner insulated box 2, reducing the impact on the inner insulated box 2 during transportation, thereby ensuring the stability of cell samples during transportation. It can also effectively reduce wear on the inner insulated box 2 and the outer insulated box 1. The spring 19 utilizes its deformable properties to make the outer insulated box 1 adaptable to different sizes of inner insulated boxes 2. At the same time, it can work with the T-shaped rod 21 to buffer and stabilize external impacts, reducing the impact of vibration on the inner insulated box 2 and the samples.

[0034] All four inner walls of the insulated outer box 1 are movably fitted with a backing plate 20. Several T-shaped rods 21 are fixedly installed on the back of the backing plate 20. The T-shaped rods 21 are embedded in the sleeve 18 and located outside the spring 19.

[0035] Reference Figure 2 The abutment plate 20 facilitates the increase of the contact area between the T-shaped rod 21 and the insulated inner box 2, thereby achieving the purpose of fully clamping the insulated inner box 2.

[0036] A second sealing ring 22 is fixedly installed on the top of the insulated outer box 1, and an end cap 23 is movably installed on the top of the insulated outer box 1.

[0037] Reference Figure 1 and Figure 2 The second sealing ring 22 facilitates the sealing of the connection between the insulated outer box 1 and the end cap 23, and can also effectively prevent gas leakage in the insulated outer box 1, thereby ensuring the stability of the temperature of the air gap in the insulated outer box 1. The end cap 23 facilitates the closure of the opening at the top of the insulated outer box 1, further enhancing the insulation of the cell samples.

[0038] Handles 24 are fixedly installed on the top of both sides of the insulated outer box 1, and self-locking casters 25 are fixedly installed at the four corners of the bottom of the insulated outer box 1.

[0039] Reference Figure 1 and Figure 2 The handle 24 facilitates operation during transport of the entire device, while the self-locking casters 25 facilitate the movement of the insulated outer box 1. The self-locking function ensures that the box remains fixed, increasing the practicality of the entire device.

[0040] Working principle: When using this device, place the cell sample container on the corresponding placement hole 9 or both sides of the isolation plate 11. The placement box 5 carries the cooling medium. After the placement box 5 is inserted into the insulated inner box 2 through the sliding groove 4, the box cover 16 is rotated to close the top opening of the insulated inner box 2. At the same time, the first sealing ring 13 is pressed, which increases the overall sealing of the insulated inner box 2. The insulated inner box 2 is placed in the insulated outer box 1. The tension of the spring 19 pushes the T-shaped rod 21. The T-shaped rod 21 drives the abutment plate 20 to clamp the insulated inner box 2. The end cover 23 is installed. The end cover 23 presses the second sealing ring 22, which increases the sealing of the insulated outer box 1. During transportation, the entire insulated box exchanges heat with the gas in the insulated inner box 2 through the contact between the cooling medium inside the placement box 5 and the gas. The cooling medium is evenly dispersed into the inner cavity of the insulated inner box 2 through the diffusion frame 7, providing a low-temperature storage environment for the cell samples in real time.
