Abstract
Description
Technical Field
[0001] This utility model relates to the field of stem cell cryogenic transport box technology, specifically a portable stem cell cryogenic transport box. Background Technology
[0002] Stem cells are a type of pluripotent cell with self-renewal capacity. Under certain conditions, they can differentiate into various functional cells. Based on their developmental stage, stem cells are classified into embryonic stem cells and adult stem cells. Based on their developmental potential, stem cells are classified into three categories: totipotent stem cells, multipotent stem cells, and unipotent stem cells. Stem cells are undifferentiated and immature cells with the potential to regenerate various tissues, organs, and the human body. They are known in the medical field as "universal cells." Stem cell storage involves isolating and culturing stem cells from different human tissues, then testing and identifying them, and finally freezing them at -196°C. This allows the stem cells to be revived and reinfused into patients when needed in clinical practice to treat diseases.
[0003] The current methods for securing stem cell storage containers are relatively simple and not stable enough. During transportation, especially when encountering bumpy road conditions, stem cell containers are prone to shaking, displacement, or even collisions. This not only increases the risk of stem cell damage but may also lead to container breakage, causing stem cell leakage and loss. To address this, we propose a portable cryogenic transport box for stem cells. Utility Model Content
[0004] The purpose of this invention is to provide a portable low-temperature stem cell transport box to solve the problem mentioned in the background art that stem cell containers are prone to shaking, displacement, or even collision during transportation, which not only increases the risk of stem cell damage but may also cause the container to rupture, resulting in stem cell leakage and damage.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable stem cell cryogenic transport box, comprising a cryogenic transport box body and a placement cavity, the placement cavity being opened inside the cryogenic transport box body, and a rail fixedly installed on both sides inside the placement cavity, with a placement plate slidably engaged on the surface of the rail, and a locking hole opened on the surface of the placement plate, a base plate fixedly connected to the bottom of the placement plate, and a limit seat provided on the surface of the base plate, an ice stacking plate fixedly installed at the intersection of the rails, and an air vent opened on the side of the ice stacking plate.
[0006] The cryogenic transport box is equipped with a lifting rod fixedly installed on the top, guide rails fixedly installed on both sides of the front of the cryogenic transport box, with grooves on the surface of the guide rails, and a snap-fit plate fixedly installed on the bottom surface of the guide rails. A sealing door is slidably snapped onto the front of the cryogenic transport box, and a handle is fixedly installed on the front of the sealing door, with an observation window above the handle.
[0007] The placement plate consists of three sets, which are slidably engaged inside the cryogenic transport box via rails.
[0008] The card holes and limiting card seats are evenly distributed on the surface of the placement plate and the base plate. The diameter of the card holes is larger than the diameter of the limiting card seats, and the card holes and limiting card seats are perpendicular to each other.
[0009] Among them, sliding plates are fixedly installed on both sides of the back of the sealed door. The sliding plates slide up and down on the surface of the slide groove and are engaged with the surface of the snap-fit plate.
[0010] Among them, the ice stacking plates are symmetrically distributed on both sides of the inside of the cryogenic transport box and are snapped into the intersection of the rail surfaces.
[0011] The ice stacking plate is connected to the corresponding card holes and limit card seats through the air vents.
[0012] This utility model has at least the following beneficial effects:
[0013] 1. The placement chamber is equipped with fixed rails on both sides. The placement plates slide and engage with the cryogenic transport box via these rails. Three sets of placement plates are provided, facilitating easy installation and removal. The placement plates have locking holes on their surfaces, and the bottom plate has retaining brackets. These holes and brackets are evenly distributed and vertically aligned, with the hole diameter larger than the retaining bracket diameter. This design allows for easy placement of containers containing stem cells (such as cryovials) between the holes and retaining brackets, providing a stable fixation and preventing displacement or collision during transport due to shaking or bumps, thus significantly improving the stability of stem cell storage.
[0014] 2. An internal ice stacking plate is installed, symmetrically distributed on both sides of the cryogenic transport chamber and engaged with the intersecting surfaces of the rails. The ice stacking plate communicates with the corresponding locking holes on the placement plate and the limiting seats on the bottom plate through vents. Cold air can flow evenly within the placement chamber through these channels, ensuring the stem cells on the placement plate are in a stable low-temperature environment. Even during long-term transport or under conditions of fluctuating external temperatures, the low temperature can be effectively maintained, preserving the stem cell activity.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a portable stem cell cryogenic transport box, including a cryogenic transport box body 100 and a placement cavity 200. The placement cavity 200 is opened inside the cryogenic transport box body 100. Rails 201 are fixedly installed on both sides inside the placement cavity 200. Placement plates 202 are slidably engaged with the surface of the rails 201. There are three sets of placement plates 202, which are slidably engaged with the inside of the cryogenic transport box body 100 via the rails 201. A locking hole 204 is provided, and the locking hole 204 and the limiting locking seat 205 are evenly distributed on the surface of the placement plate 202 and the base plate 203. The diameter of the locking hole 204 is larger than the diameter of the limiting locking seat 205, and the locking hole 204 and the limiting locking seat 205 are perpendicular to each other. The bottom of the placement plate 202 is fixedly connected to the base plate 203, and the surface of the base plate 203 is provided with the limiting locking seat 205. An ice block stacking plate 206 is fixedly installed at the intersection of the locking rails 201, and an air vent 207 is provided on the side of the ice block stacking plate 206.
[0023] A lifting rod 101 is fixedly installed on the top of the cryogenic transport box body 100. Guide rails 106 are fixedly installed on both sides of the front of the cryogenic transport box body 100. The surface of the guide rails 106 is provided with a sliding groove 107. A snap-fit plate 105 is fixedly installed on the bottom surface of the guide rails 106. A sealing door 102 is slidably snapped onto the front of the cryogenic transport box body 100. Slide plates are fixedly installed on both sides of the back of the sealing door 102. The slide plates slide up and down on the surface of the sliding groove 107 and are in contact with the surface of the snap-fit plate 105. A handle 103 is fixedly installed on the front of the sealing door 102. An observation window 104 is provided above the handle 103.
[0024] Ice stacking plates 206 are symmetrically distributed on both sides inside the body 100 of the cryogenic transport box and are snapped into the intersecting position of the surface of the rail 201. The ice stacking plates 206 are connected to the corresponding surfaces of the vent 207, the vent 204, and the limiting seat 205.
[0025] Working principle: During the preparation stage of the transport container, the staff places ice blocks on the ice block stacking plate 206. Since the ice block stacking plate 206 is symmetrically distributed on both sides of the interior of the cryogenic transport container body 100 and is engaged with the surface of the rail 201 at the intersection, this layout can make the cooling source evenly distributed in the placement cavity 200.
[0026] The ice stacking plate 206 has vents 207 on its side, which serve as outlets for cold air. After being discharged from the vents 207, the cold air flows evenly and orderly within the placement cavity 200 through the channels formed between the retaining holes 204 on the surface of the placement plate 202 and the limiting seats 205 on the surface of the base plate 203. Specifically, the cold air first escapes from the vents 207, then rises to the area of the placement plate 202, passes through the retaining holes 204, and then travels through the gaps between the limiting seats 205, achieving all-around circumferential cooling of the stem cell container placed between the retaining holes 204 and the limiting seats 205. This cold air circulation method ensures that the stem cells on the placement plate 202 are always in a stable low-temperature environment, effectively coping with potential temperature rises during long-term transportation or the impact of external temperature changes on the internal environment, thus maintaining the activity of the stem cells.
[0027] When placing stem cell containers (such as cryovials), the placement plate 202 has locking holes 204 on its surface, and the base plate 203 has limiting seats 205 on its surface. The locking holes 204 and limiting seats 205 are evenly distributed and perpendicularly aligned, with the diameter of the locking holes 204 being larger than the diameter of the limiting seats 205. The operator aligns the bottom of the stem cell container with the locking holes 204 and places it down. A portion of the container's bottom is embedded in the locking holes 204, while the side of the container contacts and is restrained by the limiting seats 205. During transportation, whether due to bumps from vehicle movement or shaking during handling, the limiting seats 205 restrict the container's displacement from the side, and the locking holes 204 support the container from the bottom, ensuring the stem cell container is securely fixed to the placement plate 202. This prevents displacement or collisions and greatly improves the stability of stem cell storage.
[0028] The cryogenic transport box body 100 has guide rails 106 installed on both sides of its front. The guide rails 106 have grooves 107 on their surfaces. The sliding plates on both sides of the back of the sealed door 102 are slidably connected to the grooves 107, and the locking plates 105 fixedly installed on the bottom surface of the guide rails 106 engage with the sliding plates. When the operator needs to open the transport box, they grasp the handle 103 on the front of the sealed door 102 and lift it upwards. The sliding plates then slide upwards along the grooves 107 until they disengage from the locking range of the locking plates 105, thus opening the sealed door 102. To close, the operation is reversed; the sealed door 102 is moved downwards, and the sliding plates slide into the grooves 107 and re-engage with the locking plates 105, sealing the transport box. This design ensures smooth opening and closing of the sealed door 102, facilitating the retrieval or storage of stem cells by the operator.
[0029] A lifting rod 101 is fixedly installed on the top of the cryogenic transport box body 100, making it convenient for staff to carry the transport box and move it. Whether it is transferring stem cells between different departments within the hospital or carrying out long-distance transportation when participating in external collaborative projects, the lifting rod 101 makes the transportation process more convenient and improves the portability of the entire transport box.
