Description

Technical Field

[0001] This utility model belongs to the field of stem cell sampling and storage, and specifically relates to a stem cell sampling and storage device with a protective structure. Background Technology

[0002] Stem cells are a type of pluripotent cell with the ability to self-renew. Under certain conditions, they can differentiate into various functional cells or tissues and organs, hence they are known in the medical field as "universal cells." Stem cells have a wide range of sources, including embryonic, fetal, and adult tissues. Embryonic stem cells, in particular, possess pluripotent differentiation characteristics and can differentiate into almost all mature cell types found in a mature individual. Adult stem cells, on the other hand, originate from adult tissues, such as hematopoietic stem cells, neural stem cells, and pancreatic stem cells.

[0003] Existing technologies have specifically developed some stem cell sampling and storage devices with protective structures. For example, Chinese patent with publication number "CN222137387U" discloses "a cell storage device clamping structure with protective function, including a pressing body and several clamping bodies. The pressing body is located at the bottom of the mounting groove and is slidably connected to the frame. Each clamping body and the pressing body are provided with a linkage structure. That is, when the test tube is inserted into the mounting groove, the pressing body is subjected to force and slides downward, thereby triggering the linkage structure, so that each clamping body clamps the test tube. This avoids the need for additional operation to control the clamping structure to clamp the test tube when installing the test tube, making this utility model easy to use."

[0004] Although a reset structure is provided between the pressing body and the frame, allowing the pressing body to automatically reset itself when the test tubes are removed from the mounting slot, facilitating reuse and ensuring the practicality of this invention, the frame cannot be removed separately during use. This increases the difficulty of cleaning the inside of the storage box and adds complexity when loading test tubes, failing to effectively improve portability. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a stem cell sampling and storage device with a protective structure to solve the problem of stem cell sampling and storage.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A stem cell sampling and storage device with a protective structure includes a storage box. The storage box has multiple square slots inside. Multiple rubber pads are fixedly installed on the inner ring of the bottom of each of the square slots. Each of the square slots has a sliding opening inside. Multiple fixing blocks are slidably installed on the inner ring of each of the square slots. Each fixing block has a fixing groove at its center at the end furthest from the storage box. Multiple bolts are rotatably installed inside each of the sliding openings. The bolts are threaded into the interior of each fixing block. Two fixing plates are fixedly installed on both sides of the upper end of each fixing block, located on either side of the fixing groove. Threaded rods are threaded into the interior of each fixing plate. A knob is integrally formed at the end of each threaded rod furthest from the fixing plates. An mounting plate is rotatably installed at the end of each mounting plate furthest from the mounting plate. A rubber limiting block is fixedly installed at the end of each mounting plate furthest from the mounting plate.

[0008] As a preferred technical solution, each of the multiple rubber pads is fixedly installed with a fixing rod around the end away from the square groove, and each of the multiple fixing blocks is provided with a fixing opening around the end near the square groove. All four fixing openings are slidably installed on the outer ring of the fixing rod.

[0009] As a preferred technical solution, one end of the near square groove of the multiple fixing blocks is fitted to the upper end of the rubber pad, and the inside of one end of the near square groove of the multiple fixing blocks is provided with a threaded opening, and the multiple bolts are connected to the inside of the threaded opening through the sliding port thread.

[0010] As a preferred technical solution, the bottom of the storage box is provided with a rectangular cavity, and multiple bolts are provided in the rectangular cavity. A cover plate is slidably installed on the upper end of the storage box, and a first handle is provided on the end of the cover plate away from the storage box.

[0011] As a preferred technical solution, both of the fixing plates have internal threaded grooves inside, and both threaded rods are threadedly connected to the inside of the two fixing plates through the internal threaded grooves.

[0012] As a preferred technical solution, bearings are fixedly installed at the ends of the two mounting plates away from the rubber limiting block, and the ends of the two threaded rods away from the knob are fixedly installed in the inner ring of the bearings.

[0013] As a preferred technical solution, limit grooves are provided on both sides of the interior of the two fixing plates, and limit rods are fixedly installed on both sides of the two mounting plates. The limit rods are slidably installed inside the limit grooves, and second handles are fixedly installed on both sides of the upper end of the fixing block away from the fixing plates.

[0014] In summary, the present invention has the following main advantages:

[0015] First, when placing the test tube into the fixing slot, the operator can turn the knobs on both sides. While turning the knobs, the threaded rod will rotate inside the fixing plate. This will push the mounting plate to move. When the mounting plate moves, the rubber limit block fixed on one side of the mounting plate will fit against the outer ring of the test tube to ensure the stability of the test tube and improve the fixing effect of the test tube.

[0016] Secondly, after prolonged use, staff need to effectively clean the inside of the storage box. At this time, staff can rotate the bolts in the rectangular cavity at the bottom of the storage box to loosen the bolts from the bottom of the storage box. Then, staff can use the second handles on both sides of the upper end of the fixing block to remove the fixing block to the outside of the storage box so that staff can better clean the inside of the storage box.

[0025] Example

[0026] refer to Figures 1-7This embodiment of a stem cell sampling and storage device with a protective structure includes a storage box 3. The storage box 3 has multiple square grooves 22 inside. Multiple rubber pads 23 are fixedly installed on the inner ring of the bottom of each of the multiple square grooves 22. Each of the multiple square grooves 22 has a sliding opening 18 inside. Multiple fixing blocks 4 are slidably installed on the inner ring of each of the multiple square grooves 22. A fixing groove 7 is opened at the center of the end of each of the multiple fixing blocks 4 away from the storage box 3. Multiple bolts 16 are rotatably installed inside each of the multiple sliding openings 18. The multiple bolts 16 are threadedly connected to the inside of the multiple fixing blocks 4. Two fixing plates 8 are fixedly installed on both sides of the upper end of the multiple fixing blocks 4 located in the fixing groove 7. Threaded rods 14 are threadedly connected inside the two fixing plates 8. A knob 13 is integrally formed on the end of each of the two threaded rods 14 away from the two fixing plates 8. An mounting plate 10 is rotatably installed on the end of each of the threaded rods 14 away from the knob 13. A rubber limiting block 6 is fixedly installed on the end of each of the two mounting plates 10 away from the mounting plate 10.

[0027] refer to Figures 4 to 5 Multiple rubber pads 23 are fixedly mounted with fixing rods 21 around the ends away from the square grooves 22. Multiple fixing blocks 4 are fixed with fixing openings 19 around the ends near the square grooves 22. The four fixing openings 19 are slidably mounted on the outer ring of the fixing rods 21. The ends of the multiple fixing blocks 4 near the square grooves 22 are fitted to the upper end of the rubber pads 23. The ends of the multiple fixing blocks 4 near the square grooves 22 are threaded with openings 20 inside. Multiple bolts 16 are threaded into the threaded openings 20 through sliding openings 18. When placing the fixing blocks 4 back, the staff needs to align the fixing openings 19 around the bottom of the fixing blocks 4 with the fixing rods 21 fixedly mounted around the rubber pads 23 for installation. After the fixing blocks 4 are installed inside the square grooves 22, they can be effectively limited to prevent the fixing blocks 4 from shaking and wobbling, thus improving the protection of the test tubes.

[0028] refer to Figures 1 to 2 The storage box 3 has a rectangular cavity 17 at the bottom, and multiple bolts 16 are located in the rectangular cavity 17. A cover plate 2 is slidably installed on the upper end of the storage box 3. A first handle 1 is provided on the end of the cover plate 2 away from the storage box 3, so that the staff can slide the cover plate 2 slidably installed on the upper end of the storage box 3 out.

[0029] refer to Figure 3Both fixing plates 8 have internal threaded grooves 12. Two threaded rods 14 are threadedly connected to the two fixing plates 8 through the internal threaded grooves 12. Bearings 15 are fixedly installed on the ends of the two mounting plates 10 away from the rubber limiting block 6. The ends of the two threaded rods 14 away from the knob 13 are fixedly installed on the inner ring of the bearing 15. Limiting grooves 11 are opened on both sides of the interior of the two fixing plates 8. Limiting rods 9 are fixedly installed on both sides of the two mounting plates 10. The limiting rods 9 are slidably installed in the limiting grooves 11. Second handles 5 are fixedly installed on both sides of the upper end of the fixing block 4 away from the fixing plate 8. When the test tube is placed into the fixing groove 7, the operator can turn the knobs 13 on both sides. When the knobs 13 are turned, the threaded rods 14 will rotate inside the fixing plate 8. In this way, the threaded rods 14 will push the mounting plate 10 to move. When the mounting plate 10 moves, the rubber limiting block 6 fixedly installed on one side of the mounting plate 10 will fit against the outer ring of the test tube to ensure the stability of the test tube and improve the fixing effect of the test tube.

[0030] Operating principle and advantages: When test tubes need to be stored, the operator can slide out the cover 2, which is slidably mounted on the upper end of the storage box 3. To do this, the operator needs to pull the cover 2 using the first handle 1, revealing the interior of the storage box 3. The operator then places the test tubes to be stored into the fixing slots 7 inside the multiple fixing blocks 4. While placing the test tubes into the fixing slots 7, the operator can rotate the knobs 13 on both sides. Simultaneously, the threaded rod 14 rotates inside the fixing plate 8, thus pushing the mounting plate 10 to move. As the mounting plate 10 moves, the rubber limiting block 6 fixedly mounted on one side of the mounting plate 10 will fit against the outer ring of the test tube, ensuring the stability of the test tube and improving its fixing effect. When the mounting plate 10 moves, the limiting rods 9 fixedly mounted on both sides of the moving plate will slide... The mounting plate 10 is positioned inside the fixed plate 8, which ensures that the mounting plate 10 is less likely to get stuck during movement and improves the stability of the mounting plate 10. After long-term use, the staff needs to effectively clean the inside of the storage box 3. At this time, the staff can rotate the bolts 16 in the rectangular cavity 17 at the bottom of the storage box 3 to disengage multiple bolts 16 from the bottom of the storage box 3. Then, the staff can use the second handles 5 on both sides of the upper end of the fixed block 4 to take the fixed block 4 out to the outside of the storage box 3 so that the staff can better clean the inside of the storage box 3. When putting the fixed block 4 back, the staff needs to align the fixing holes 19 opened around the bottom of the fixed block 4 with the fixing rods 21 fixed around the rubber pad 23 for installation. After the fixed block 4 is installed in the square groove 22, it can effectively limit the fixed block 4 to prevent the fixed block 4 from shaking and wobbling, thus improving the protection of the test tube.
