Description

Technical Field

[0001] This utility model relates to the field of stem cell preservation technology, specifically to a stem cell exosome preservation device. Background Technology

[0002] Stem cells possess characteristics such as self-renewal, unlimited proliferation, and multi-directional differentiation potential. Based on developmental potential, stem cells can be divided into three main categories: totipotent stem cells, pluripotent stem cells, and unipotent stem cells; based on their developmental stage, they can be divided into two main categories: embryonic stem cells and adult stem cells.

[0003] Application number CN202121495218.0 discloses a stem cell exosome preservation device capable of real-time temperature control around the storage container, ensuring the temperature inside the storage tank remains between 4-8°C. This device controls the temperature outside the preservation unit without the need for refrigerants or electricity, thus preventing external heat from being conducted into the device and disrupting the internal temperature balance. This ensures the internal temperature is unaffected by external environmental factors, guaranteeing effective preservation of stem cell exosomes. Real-time intelligent control of the internal temperature ensures smooth airflow at the bottom of the device, preventing heat accumulation. However, this design has shortcomings. Multiple boxes cannot be stacked, occupying significant storage space. During handling and transportation, disorderly placement can easily cause boxes to tip over or collide, damaging the stem cell exosome sample tubes inside and interfering with the accuracy of subsequent detection and analysis.

[0004] Therefore, we propose a stem cell exosome preservation device. Utility Model Content

[0005] The main purpose of this invention is to provide a stem cell exosome preservation device. Through the design of the storage box, the device body can be protected in all directions. The protective pads on the inner wall of the cavity and the rubber pads on the limiting components form a double buffer protection structure, which can effectively absorb the impact force generated during handling and transportation, avoid damage to the stem cell exosome sample tubes inside the box due to collision, and ensure the integrity and activity of the sample. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A stem cell exosome preservation device includes a storage box and a preservation device body. The storage box is a horizontally arranged rectangular structure. Positioning plates are fixedly connected to both ends of the upper surface of the storage box. Positioning protrusions are provided on the upper surface of the positioning plates. Limiting plates are fixedly connected to both ends of the lower surface of the storage box. Grooves that match the positioning protrusions are provided on the lower surface of the limiting plates. The upper and lower sets of the storage boxes are stacked and placed through the positioning plates and limiting plates.

[0008] The storage box has a protective cavity for placing the main body of the storage device. One side of the storage box has an opening that communicates with the protective cavity. The two ends of the storage box near the opening have slots for installing limiting components. Both ends of the limiting components have inserts that are adapted to the slots. The inserts are fixedly connected to the two ends of the storage box by self-tapping screws.

[0009] By adopting the above technical solution and through the design of the storage box, the main body of the preservation device can be protected in all aspects. The protective pads on the inner wall of the cavity and the rubber pads on the limiting components form a double buffer protection structure, which can effectively absorb the impact force generated during handling and transportation, avoid damage to the stem cell exosome sample tubes inside the box due to collision, ensure the integrity and activity of the samples, and reduce the waste of scientific research resources and the increase in time costs caused by sample damage.

[0010] Specifically, a protective pad is fixedly glued to the inner wall of the protective cavity, and the protective pad is placed on the main body of the storage device.

[0011] Specifically, the storage box has retrieval slots at both the top and bottom of the side near the opening.

[0012] Specifically, a rubber pad is fixedly glued to the center of the limiting member near the insertion block, and the side of the rubber pad away from the limiting member contacts the side of the storage device body.

[0013] Specifically, a first anti-slip pad is fixedly glued to the lower end face of the limiting plate.

[0014] Specifically, the top of the positioning protrusion is inserted into the groove, and a second anti-slip pad is fixedly glued to the upper surface of the positioning protrusion.

[0015] The beneficial effects of this utility model are as follows: The stem cell exosome preservation device described in this utility model, through the design of the storage box, can protect the main body of the preservation device in all aspects. The protective pads on the inner wall of the cavity and the rubber pads on the limiting parts form a double buffer protection structure, which can effectively absorb the impact force generated during handling and transportation, avoid damage to the stem cell exosome sample tubes inside the box due to collision, ensure the integrity and activity of the sample, and reduce the waste of scientific research resources and the increase in time costs caused by sample damage.

[0016] The storage boxes are designed for stacking using positioning and limiting plates, which greatly improves the utilization of storage space. Compared to boxes that cannot be stacked, they can store more stem cell exosome samples in the same space, reducing storage costs. The presence of the first and second anti-slip pads ensures the stability of the storage boxes when stacked, reducing the risk of boxes tipping over due to unstable stacking, further ensuring sample safety and facilitating the transportation of stem cell exosome samples.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As one embodiment of this utility model, such as Figures 1-3 As shown, the stem cell exosome preservation device of this utility model includes a storage box 1 and a preservation device body 4. The storage box 1 is a horizontally arranged rectangular structure. Positioning plates 8 are fixedly connected to both ends of the upper surface of the storage box 1. Positioning protrusions 9 are provided on the upper surface of the positioning plates 8. Limiting plates 10 are fixedly connected to both ends of the lower surface of the storage box 1. The lower surface of the limiting plates 10 is provided with grooves 11 that are adapted to the positioning protrusions 9. The upper and lower sets of storage boxes 1 are stacked and placed through the positioning plates 8 and the limiting plates 10.

[0024] The storage box 1 has a protective cavity 2 for placing the storage device body 4. One side of the storage box 1 has an opening 16 communicating with the protective cavity 2. The two ends of the storage box 1 near the opening 16 have slots 14 for installing limiting members 6. Both ends of the limiting member 6 have plugs 12 that are adapted to the slots 14. The plugs 12 are fixedly connected to the two ends of the storage box 1 by self-tapping screws 7.

[0025] When using,

[0026] This utility model also includes a protective pad 3 fixedly glued to the inner wall of the protective cavity 2, and the protective pad 3 is sleeved on the main body 4 of the storage device.

[0027] This utility model also includes that the top and bottom of the storage box 1 near the opening 16 are provided with retrieval slots 5.

[0028] The present invention also includes a rubber pad 13 fixedly glued at the center of the side of the limiting member 6 near the insert block 12, and the side of the rubber pad 13 away from the limiting member 6 is in contact with the side of the storage device body 4.

[0029] This utility model also includes a first anti-slip pad 15 fixedly glued to the lower end face of the limiting plate 10.

[0030] The present invention also includes that the top end of the positioning protrusion 9 is inserted into the groove 11, and a second anti-slip pad is fixedly glued to the upper end surface of the positioning protrusion 9.

[0031] When using this invention, if it is necessary to transport the main body 4 of the preservation device containing the stem cell exosome sample tube, firstly, the main body 4 of the preservation device is horizontally inserted into the protective cavity 2 on one side of the storage box 1. Since the inner wall of the protective cavity 2 is fixed with a protective pad 3, the protective pad 3 will be placed on the main body 4 of the preservation device to provide initial cushioning protection and avoid direct contact between the main body 4 of the preservation device and the storage box 1 and collision. Then, the insert 12 of the limiting member 6 is inserted into the slots 14 at both ends of the storage box 1 near the opening 16. Then, the self-tapping screws 7 are used to fix the insert 12 to both ends of the storage box 1, so that the main body 4 of the preservation device can be fixed in the storage box 1.

[0032] Align the limiting plate 10 on the lower end face of the upper storage box 1 with the positioning plate 8 on the upper end face of the lower storage box 1, so that the positioning protrusion 9 is inserted into the groove 11, thereby achieving stable stacking of the upper and lower sets of storage boxes 1. At the same time, the second anti-slip pad on the upper end face of the positioning protrusion 9 and the first anti-slip pad on the lower end face of the limiting plate 10 can increase friction and prevent sliding misalignment during stacking, which greatly improves the utilization rate of storage space. Compared with boxes that cannot be stacked, more stem cell exosome samples can be stored in the same space, reducing storage costs.
