Description

Technical Field

[0001] This utility model specifically relates to a stem cell transport box. Background Technology

[0002] Stem cells are a type of cell with self-renewal and multi-directional differentiation potential. They are characterized by strong self-renewal, differentiation ability, high plasticity, and low immunogenicity, and have broad application prospects in the fields of medicine, scientific research, and biotechnology.

[0003] The transportation of stem cells is a critical process, requiring them to be kept within a specific temperature range during transport, typically a cryogenic environment of 2–8°C. Currently, stem cell transportation often uses conventional insulated boxes, with ice packs placed inside to create a low-temperature environment. While this method effectively keeps stem cells in a low-temperature environment, directly stacking ice packs and test tubes together not only results in a chaotic arrangement but also risks issues such as ice packs being too close to the test tubes, leading to excessively low temperatures and potential stem cell damage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention proposes a stem cell transport box that can be used to preserve stem cell test tubes in a low-temperature environment.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a stem cell transport box, comprising a box body and a refrigeration storage structure;

[0006] The top of the box is equipped with an openable and closable lid, and the bottom of the box is provided with multiple test tube slots;

[0007] The refrigeration storage structure includes a box and an opening assembly. The box is located at the bottom of the cabinet, and the bottom of the box has multiple through holes communicating with the box. Refrigerant pipes can be inserted into the through holes. The bottom of the box has an opening, and the opening assembly is located at the opening, which can open or close the opening.

[0008] Open the lid to place the test tubes containing stem cells into the test tube slot, then close the lid. Open the opening at the bottom of the box using the opening assembly, insert the refrigerant tubing through the through-hole into the box to create a low-temperature environment, then close the opening to begin transferring stem cells.

[0009] The advantages of the aforementioned stem cell transport box are: by setting up test tube slots and through holes, test tubes and refrigerant tubes can be placed separately to avoid confusion and prevent damage caused by them being too close together. Furthermore, the refrigerant tubes are inserted into the box from the bottom, avoiding contact with the test tubes during handling and facilitating refrigerant tube replacement.

[0010] Furthermore, the refrigerant pipe is interference-fitted with the through hole.

[0011] An interference fit ensures that the refrigerant pipes are placed securely.

[0012] Furthermore, the opening assembly includes a baffle, a central seat, and an annular rod. The opening is circular, the baffle is fan-shaped, and multiple baffles are arranged around the circumference of the central seat. Both ends of the baffle are provided with a rotating shaft, which is rotatably connected to the central seat and the opening, respectively. The baffle and the central seat can jointly close the opening.

[0013] The annular rod is rotatably mounted on the outer wall of the opening. Multiple push rods are arranged circumferentially on the annular rod. The rotating shaft connecting the baffle to the opening extends to the outer wall of the opening and is connected to a connecting rod. The connecting rod has a strip-shaped hole along the axial direction, and the push rod is slidably inserted into the strip-shaped hole.

[0014] Rotating the ring rod relative to the opening allows the push rod to slide within the slot, driving the connecting rod and the rotating shaft to rotate, which in turn drives the baffle to rotate. The rotation of the ring rod can drive multiple baffles to rotate simultaneously, opening the opening to allow the refrigerant pipe to be inserted or removed.

[0015] Furthermore, the ring rod is provided with a handle.

[0016] The handle allows the user to easily rotate the ring rod.

[0017] Furthermore, the outer wall of the housing is provided with a movable pin, and the handle is provided with a pin hole into which the pin can be inserted.

[0018] When it is not necessary to open the box, the pin can be inserted into the pin hole to prevent the ring rod from rotating and keep the baffle in a closed state. Attached Figure Description

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0027] Please see Figures 1 to 3 This utility model provides a stem cell transport box, including a box body 10 and a refrigeration storage structure 20. Test tubes containing stem cells are placed inside the box body 10. The refrigeration storage structure 20 can accommodate a refrigerant tube to create a low-temperature environment inside the box for the storage of stem cells.

[0028] Specifically, the top of the box 10 is provided with an openable and closable lid 11, and the bottom is provided with multiple test tube slots 101 for storing test tubes. The refrigeration storage structure 20 includes a box body 21 and an opening assembly 22. The box body 21 is located at the bottom of the box 10, and the bottom of the box body 10 is provided with multiple through holes 102 communicating with the box body 21 for inserting refrigerant pipes. The bottom of the box body 21 is provided with an opening 211, and the opening assembly 22 is located at the opening 211, which can open or close the opening.

[0029] Open the lid 11 and place the test tube containing stem cells into the test tube slot 101, then close the lid 11 for storage. The opening 211 at the bottom of the box 21 can be opened via the opening assembly 22. Insert the refrigerant tube through the through-hole 102 into the box 10 to create a low-temperature environment inside. Then close the opening 211 to begin transferring stem cells. By placing the test tubes and refrigerant tubes separately, the test tubes can be stored at low temperatures while avoiding contact damage. Furthermore, inserting the refrigerant tube from below also prevents contact with the test tubes during insertion.

[0030] In this embodiment, the refrigerant pipe is filled with a high-polymer compound phase change cold storage material. The refrigerant pipe is interference-fitted with the through hole 102, and this interference fit ensures the stable placement of the refrigerant pipe.

[0031] Specifically, the opening assembly 22 includes a baffle 221, a center seat 222, and an annular rod 223. The opening 211 is circular, and the baffle 221 is fan-shaped. Multiple baffles 221 are arranged circumferentially around the center seat 222, which is located at the center of the opening 211. The baffles 221 and the center seat 222 can jointly close the opening 211. Both ends of the baffle 221 are provided with rotating shafts 224, which are rotatably connected to the center seat 222 and the opening 211, respectively. The annular rod 223 is rotatably mounted on the outer wall of the opening 211 and is provided with multiple push rods 225 circumferentially. The rotating shafts 224 connecting the baffle 221 and the opening 211 extend to the outer wall of the opening 211 and are connected to a connecting rod 226. The connecting rod 226 has a strip-shaped hole along the axial direction, and the push rods 225 are slidably inserted into the strip-shaped hole.

[0032] Rotating the ring rod 223 relative to the opening 211 allows the push rod 225 to slide within the slot, driving the connecting rod 226 and the rotating shaft 224 to rotate, thereby causing the baffle 221 to rotate. The ring rod 223 can simultaneously drive multiple baffles 221 to rotate together, thus opening the opening 211 to allow the refrigerant pipe to be inserted or removed.

[0033] In addition, for ease of operation, a handle 227 is provided on the ring rod 223 for rotating the ring rod 223. The outer wall of the housing 10 is provided with a movable pin, and the handle 227 is provided with a pin hole 228 into which the pin can be inserted. When it is not necessary to open the opening 211 of the housing 21, the pin can be inserted into the pin hole 228, so that the ring rod 223 cannot be rotated, keeping the baffle 221 in a closed state of the opening 211.

[0034] The working principle of the aforementioned stem cell transport box is as follows: Open the box cover 11 and place the test tube containing stem cells into the test tube slot 101 at the bottom of the box body 10, then close the box cover 11. After removing the pin, rotate the ring rod 223, which drives the connecting rod 226 and the rotating shaft 224 to rotate via the push rod 225, thereby rotating the baffle 221 and opening the opening 211 at the bottom of the box body 21. Place the refrigerant tube into the box body 21 and insert it into the box body through the through hole 102. The refrigerant tube and the through hole 102 are fixed by an interference fit, which can cool the inside of the box body. After closing the baffle, lock the ring rod 223 with the pin, and the transfer of stem cells can begin.

[0035] Using the aforementioned stem cell transport box allows for the separate placement of test tubes and refrigerant tubing to prevent contact and improve the safety of the test tubes during transport. Furthermore, inserting the refrigerant tubing through the bottom opening also avoids contact with the test tubes, ensuring the safety of the test tubes when inserting or removing the refrigerant tubing.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
