Description

Technical Field

[0001] This utility model relates to the field of stem cell sample technology, and in particular to a portable stem cell sample transport box. Background Technology

[0002] Stem cells are a type of cell with self-renewal and differentiation potential, possessing immense application value in the medical field. Recent years have seen significant progress in stem cell research, bringing unprecedented changes to medicine. With the continuous development of stem cell research and applications, the demand for transporting stem cell samples is also increasing.

[0003] Currently, the most common methods for storing stem cell samples are liquid nitrogen storage and freeze-drying. Liquid nitrogen storage involves placing stem cell samples in special cryopreservation bags and then freezing them in a liquid nitrogen tank at -196°C. The tank integrates a liquid nitrogen storage and evaporative cooling system, utilizing the low temperature (-196°C) of liquid nitrogen to achieve an ultra-low temperature freezing environment for the samples. This tank typically includes a liquid nitrogen storage chamber, an insulation layer, temperature sensors, and an evaporation control system. This method allows stem cells to maintain their viability for extended periods, but the cryopreservation bags need to be checked regularly to prevent liquid nitrogen leakage. Freeze-drying, on the other hand, involves first freezing the stem cell samples at low temperatures and then using vacuum drying to evaporate the moisture, achieving long-term preservation. This method is suitable for storing small quantities of stem cells.

[0004] In the transportation of stem cell samples, specialized transport boxes are typically used. These boxes are equipped with liquid nitrogen freezing equipment, and existing transport boxes generally use lightweight materials to reduce overall transport weight and achieve portability. For example, the "Portable Transport Box for Stem Cells" patented by Shenyang Fuzhibo Biotechnology Co., Ltd. is reasonably designed, compact in structure, easy to carry and move, provides a low-temperature freezing environment for stem cells, and also has structures such as heat insulation tiles and vibration damping cotton to effectively protect stem cells from the influence and damage of the external environment. However, the existing transportation methods have certain problems. Multiple stem cell samples are usually placed directly in the transport box without an effective identification mechanism. This makes it difficult for staff to quickly and accurately distinguish different samples when using these samples, which not only reduces work efficiency but may also lead to sample confusion due to mishandling, affecting subsequent research and treatment work.

[0005] Therefore, designing a technical solution that can effectively address the problem of difficulty in distinguishing stem cell samples within the transport container has become an urgent issue to be solved. Utility Model Content

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Reference Figures 1-5 This embodiment of the present invention provides a portable stem cell sample transport box, including a box 1 with liquid nitrogen freezing function. The box 1 with liquid nitrogen freezing function is the core structure for maintaining the low temperature preservation of stem cell samples. It integrates a liquid nitrogen storage and evaporative cooling system, and achieves an ultra-low temperature freezing environment for the samples through the low temperature characteristics (-196℃) of liquid nitrogen. The box typically includes a liquid nitrogen storage chamber, an insulation layer, a temperature sensor, and an evaporation control system (which are conventional technical means in the field of low temperature transport of biological samples, not shown in the figure). This application mainly addresses the problem of classifying and placing stem cell samples. The box 1 with liquid nitrogen freezing function is used directly without changing its function and principle. It also includes a moving mechanism, which is set at the bottom of the box 1 with liquid nitrogen freezing function and is used to drive the box 1 with liquid nitrogen freezing function to move flexibly.

[0033] The moving mechanism includes a moving box 10, which is fixedly connected to the bottom end of the box 1 with liquid nitrogen freezing function. A sliding plate 11 is slidably connected inside the moving box 10, and multiple moving wheels 12 are fixedly connected to the sliding plate 11. A sliding assembly 13 for driving the sliding plate 11 to slide is provided on the moving box 10. The sliding assembly 13 includes an extension plate 1301, which is fixedly connected to the moving box 10. A sliding rod 1302 is fixedly connected between the extension plate 1301 and the moving box 10, and the sliding plate 11 is slidably sleeved on the sliding rod. On 1302, a sliding plate 11 is provided with a sliding component, which includes an extension plate 1303. The extension plate 1303 is fixedly connected to the movable box 10. A screw 1304 is rotatably connected between the extension plate 1303 and the movable box 10. The sliding plate 11 is threaded onto the screw 1304. A rotating component is provided on the screw 1304. The rotating component includes a motor 1305. The motor 1305 is fixedly installed on the extension plate 1303. The output end of the motor 1305 passes through the extension plate 1303 and is concentrically connected to the screw 1304.

[0034] Correspondingly, the moving mechanism drives the screw 1304 to rotate via the motor 1305, which in turn drives the threaded sliding plate 11 to move up and down along the sliding rod 1302, thereby realizing the lifting function of the moving wheel 12. When transportation is required, the moving wheel 12 is lowered to facilitate the movement of the box. After reaching the fixed position, the moving wheel 12 is raised to stabilize the box. The use of electric control improves the ease of operation. The dual guide structure of the sliding rod 1302 and the screw 1304 ensures the accuracy of movement and effectively solves the problem of inconvenience in switching between the moving and fixed states of traditional transport boxes.

[0035] Multiple support plates 2 are fixedly connected to the box 1 with liquid nitrogen freezing function. Storage drawers 3 are slidably connected to the support plates 2 and the inner bottom wall of the box 1 with liquid nitrogen freezing function. A limiting component 4 is provided between the storage drawer 3 and the box 1 with liquid nitrogen freezing function. The limiting component 4 includes a rotating shaft 401, which is fixedly connected to the box 1 with liquid nitrogen freezing function. A rotating block 402 is rotatably sleeved on the rotating shaft 401. A limiting block 403 is fixedly connected to the storage drawer 3. A limiting groove matching the rotating block 402 is opened on the limiting block 403. Multiple protrusions 4021 are provided on the outer side wall of the rotating block 402, and a groove matching the multiple protrusions 4021 is provided on the inner wall of the limiting groove. A handle 4022 is also provided on the top of the rotating block 402.

[0036] Correspondingly, the limiting component 4 locks the drawer by engaging the rotating block 402 on the rotating shaft 401 with the limiting block 403. The protrusion 4021 and the groove form a ratchet structure. Rotating the handle 4022 can cause the rotating block 402 to engage in the limiting groove, thus achieving stable limiting of the storage drawer 3 and ensuring that the storage drawer will not accidentally slide out during transportation, significantly improving the safety and convenience of sample storage and retrieval.

[0037] A partition 5 is fixedly connected to the storage drawer 3. Multiple sorting boards 6 are fixedly connected to both the partition 5 and the inner side wall of the storage drawer 3. A storage box 7 is placed between the multiple sorting boards 6. A box cover 8 is hinged to the storage box 7. A fixing component 9 is provided between the box cover 8 and the storage box 7. The fixing component 9 includes a front hook and loop fastener 901, which is fixedly connected to the storage box 7. A back hook and loop fastener 902 that matches the front hook and loop fastener 901 is fixedly connected to the box cover 8. An identification card 801 is provided on the top of the box cover 8. The sorting boards 6 are made of polyurethane foam.

[0038] Correspondingly, the classification system uses a classification board 6 made of polyurethane foam to form a grid structure, which physically separates and stores samples. The Velcro fastening component 9 uses the adhesive properties of the mother and daughter surfaces to enable the quick opening and closing of the lid 8, which ensures both airtightness and easy one-handed operation. The label card 801 is designed to support the labeling of sample information. Combined with the elastic cushioning polyurethane foam material, it can effectively reduce shock and prevent sample damage during transportation, and improve the efficiency of sample management through the visual labeling system. It is particularly suitable for the transportation needs of stem cell samples that require multiple batches of classification and preservation.

[0039] The working principle of this portable stem cell sample transport box is as follows: First, ensure that the box 1 with liquid nitrogen freezing function is filled with an appropriate amount of liquid nitrogen to maintain a low temperature environment. Then, drive the screw 1304 to rotate through the motor 1305, which drives the sliding plate 11 to descend along the sliding rod 1302, so that the moving wheel 12 contacts the ground, making it easy to push the box to the designated position. After reaching the position, start the motor 1305 again to make the sliding plate 11 rise, the moving wheel 12 leave the ground, and the box is placed stably. Then, open the limiting component 4 of the storage drawer 3, take out the storage drawer 3, put the stem cell sample into the storage box 7 between the classification plates 6, close the box cover 8 and fix it with the fixing component 9. Fill in the sample information on the identification card 801 on the top of the box cover 8 for easy identification and management. Then lock the storage drawer 3. Sealing strips are set at the gaps between the storage drawer 3 and the box 1 with liquid nitrogen freezing function to ensure airtightness. During transportation, the classification plate 6 made of polyurethane foam provides shock absorption protection.

[0040] It should be noted that when operating the moving mechanism, a stable power supply must be ensured to avoid sudden power outages that could prevent the moving wheels 12 from fully lifting or lowering. When storing samples, ensure that the samples are properly sealed in cryopreservation bags to prevent liquid nitrogen from directly contacting the samples and causing damage. Regularly check the liquid nitrogen level and replenish it in time to ensure that the chamber maintains a low-temperature environment. During transportation, avoid violent vibrations and impacts to prevent sample damage.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
