Technical Field
[0001] This utility model relates to the field of stem cell preparation preservation and transportation technology, specifically to a stem cell preparation preservation and transportation device. 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. 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 further classified into three categories: totipotent stem cells, multipotent stem cells, and unipotent stem cells. Stem cells are undifferentiated, immature cells with the potential to regenerate various tissues, organs, and the human body; they are known in the medical field as universal cells.
[0003] Stem cell preparations need to be stored at low temperatures, so the prepared stem cell preparations need to be placed in a low-temperature storage box for storage and transportation.
[0004] The existing technology has the following problems: When using existing devices, stem cell preparations need to be transported at low temperatures. When handling stem cell preparations, hands need to be frequently inserted into the storage box. Although thick gloves are worn, this increases the time spent in contact with cold air, which can easily cause frostbite and make it inconvenient to handle. Utility Model Content

A placement plate is fixedly mounted on the bottom of the side plate, and multiple sets of through holes are formed on the surface of the placement plate. The placement plate has sliders fixed at both ends. A sponge pad is fixed at the middle of the upper side of the placement plate. Slots are opened on both sides of the surface of the sponge pad. A crossbeam is fixed at the middle of the upper end of the placement plate. Multiple sets of fixed seats are fixed on one side of the crossbeam. Uprights are fixed on both sides of the upper end of the placement plate. Multiple sets of sliding rods are slidably installed on the inner side of the uprights. A pull plate is fixed at the bottom of the sliding rod. A spring is sleeved on the front end of the sliding rod. A movable frame is fixed at the front end of the sliding rod. Multiple sets of movable seats are fixed at one end of the movable frame.
[0006] Preferably, the worm and the worm wheel mesh with each other, a dust cover is fixedly sleeved on the outside of the worm and the worm wheel, and the outer end of the placement plate is slidably connected to the inside of the storage box.
[0007] Preferably, the slider is slidably installed with the slide groove, the two ends of the spring are fixedly connected to the opposite surfaces of the movable frame and the upright frame, and the opposite surfaces of the movable seat and the fixed seat are both arc-shaped.
[0008] Preferably, the ice storage structure includes a groove, which is formed inside the lower end of the storage box. A placement frame is movably installed inside the groove. An end plate is fixedly provided at the front end of the placement frame. Both ends of the end plate are fixedly provided with locking posts. A damping shaft is rotatably installed on the lower front side of the storage box. A card holder is fixedly sleeved on the outside of the damping shaft. A locking slot is provided on the top of the card holder. Through grooves are provided on both sides of the interior of the storage box. A strip groove is provided on the lower side of the through groove. Multiple sets of through holes are provided on both sides of the inner wall of the storage box.
[0009] Preferably, the locking post is T-shaped, the locking slot is fitted with the locking post and is movably installed, and the placement frame is connected to the strip groove.
[0010] Preferably, the strip groove is connected to the interior of the storage box via a through groove and a through hole.
[0011] Preferably, the sealing gasket is placed inside the upper part of the storage box.
[0012] Preferably, the through holes one and two facilitate the diffusion of cold air from the dry ice placed in the frame within the storage box.
[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a stem cell preparation preservation and transportation device. A placement mechanism allows stem cell preparation to be filled into test tubes. By pulling a pull plate backward, the pull plate moves a sliding rod, a movable frame, and a movable seat synchronously, moving the movable seat away from the fixed seat. At this point, the stem cell preparation test tube can be inserted into a slot on a sponge pad. Then, the pull plate can be released, and the elastic effect of the compression spring allows the fixed seat and movable seat to clamp and fix the test tube. A rotating transmission rod drives the reel to reverse, loosening the suspension rope. This rope allows the placement plate to slowly descend into the storage box, facilitating the storage and transportation of the fixed stem cell preparation test tubes. Conversely, a forward rotation of the transmission rod and reel rewinds the suspension rope, allowing the placement plate to slowly rise, making it easier for staff to directly retrieve the stem cell preparation test tubes without reaching into the storage box and avoiding contact with cold air, thus ensuring convenient access.
[0014] This invention provides a stem cell preparation preservation and transportation device. Through a placement structure, cooling dry ice can be placed within a placement frame, allowing the frame to be positioned within a groove. By rotating a clamp, the clamp's latch engages with the clamping posts on both sides of the upper plate of the placement frame, thus limiting the placement frame and preventing it from falling off. The cold air generated by the dry ice within the placement frame can be directly diffused into the lower part of the storage box through a through-hole. At the same time, the cold air can also diffuse through a strip groove into the through-grooves at both ends of the storage box, and then diffuse through multiple sets of through-holes into the upper part of the storage box. This allows for low-temperature placement of the stem cell preparation test tubes within the storage box, providing a low-temperature environment for the stem cell preparation test tubes.

[0017] The present invention will be further described in detail below with reference to embodiments: like Figures 1-6 As shown, this utility model provides a stem cell preparation preservation and transportation device, including a storage box 1, a placement mechanism 2 inside the storage box 1, a box cover 3 hinged to the top of the storage box 1, a handle 4 fixedly provided on the upper side of the box cover 3, an ice storage structure 5 at the bottom of the storage box 1, a sealing gasket 6 fixedly provided on the lower side of the box cover 3, and multiple sets of through holes 7 opened at the bottom of the inner cavity of the storage box 1.
[0018] The sealing gasket 6 is placed inside the upper part of the storage box 1.
[0019] Through holes 7 and 210 facilitate the diffusion of cold air from the dry ice placed in frame 52 within storage box 1.
[0020] In this design, the sealing gasket 6 can improve the airtightness between the lid 3 and the storage box 1 after the lid is closed.
[0021] like Figures 3-4As shown, the placement mechanism 2 includes a transmission rod 21, both ends of which are rotatably mounted to the upper inner sides of the storage box 1. A drum 22 is fixedly sleeved on the outside of the transmission rod 21, and a lifting rope 23 is wound on the drum 22. Side plates 24 are symmetrically fixed on the upper front side of the storage box 1. A worm gear 25 is rotatably connected to the inner side of the side plate 24. A motor 26 is fixedly mounted on one end of the side plate 24. A worm wheel 27 is driven and installed at the top of the transmission rod 21. Sliding grooves 28 are opened on the front and rear inner walls of the storage box 1. A placement plate 29 is fixedly mounted on the bottom end of the side plate 24. Multiple sets of through holes 210 are opened on the surface of the placement plate 29. Both the front and rear ends of the placement plate 29 are fixedly mounted. A slider 211 is fixedly provided. A sponge pad 212 is fixedly provided on the upper middle part of the placement plate 29. Slots 213 are provided on both sides of the surface of the sponge pad 212. A crossbeam 214 is fixedly provided on the upper middle part of the placement plate 29. Multiple sets of fixed seats 215 are fixedly provided on one side of the crossbeam 214. Uprights 216 are fixedly provided on both sides of the upper end of the placement plate 29. Multiple sets of sliding rods 217 are slidably installed on the inner side of the uprights 216. A pull plate 218 is fixedly provided at the bottom end of the sliding rod 217. A spring 219 is sleeved on the front end of the sliding rod 217. A movable frame 220 is fixedly provided at the front end of the sliding rod 217. Multiple sets of movable seats 221 are fixedly provided at one end of the movable frame 220.
[0022] The worm 25 and the worm wheel 27 are meshed together. The worm 25 and the worm wheel 27 are fixedly fitted with dust covers. The outer end of the placement plate 29 is slidably connected to the inside of the storage box 1.
[0023] The slider 211 is slidably installed with the slide groove 28, and the two ends of the spring 219 are fixedly connected to the opposite surfaces of the movable frame 220 and the upright frame 216. The opposite surfaces of the movable seat 221 and the fixed seat 215 are both arc-shaped.
[0024] In this design, the sponge pad 212 is soft and has good cushioning properties, which can provide initial protection for the test tube. With the clamping cooperation of the fixed seat 215 and the movable seat 221, it can effectively prevent the test tube from being damaged by collision during transportation and prevent stem cell leakage. The curved inner walls of the fixed seat 215 and the movable seat 221 are glued with silicone pads to protect the test tube and prevent damage. The through hole 210 facilitates the circulation of cold air.
[0025] In this design, when the placement plate 29 moves up and down, it can drive the slider 211 to slide synchronously in the slide groove 28, thereby limiting its movement and making it move smoothly. By winding up the suspension rope 23, the placement plate 29 will slowly rise until it reaches a height that is convenient for staff to operate, thus making it easy for staff to directly take out stem cell preparation test tubes without having to put their hands into the storage box 1, avoiding contact between their hands and the low temperature air inside the storage box 1.
[0026] like Figures 5-6As shown, the ice storage structure 5 includes a groove 51, which is located inside the lower end of the storage box 1. A placement frame 52 is movably installed inside the groove 51. An end plate 53 is fixedly installed at the front end of the placement frame 52. Both ends of the end plate 53 are fixedly provided with locking posts 54. A damping shaft 55 is rotatably installed on the lower front side of the storage box 1. A card holder 56 is fixedly sleeved on the outside of the damping shaft 55. A slot 57 is opened on the top of the card holder 56. Through grooves 58 are opened on both sides of the interior of the storage box 1. A strip groove 59 is opened on the lower side of the through groove 58. Multiple sets of through holes 510 are opened on both sides of the inner wall of the storage box 1.
[0027] The locking post 54 is T-shaped, the locking slot 57 fits into the locking post 54 and is movably installed, and the placement frame 52 is connected to the strip groove 59.
[0028] The strip groove 59 is connected to the interior of the storage box 1 via the through groove 58 and the through hole 510.
[0029] In this design, the cold air generated by the sublimation of dry ice in the placement frame 52 first penetrates directly into the lower part of the storage box 1 through the through hole 7 at the bottom of the placement frame 52, rapidly reducing the temperature of the bottom area of the storage box 1. At the same time, some of the cold air diffuses to both sides through the strip groove 59 on the side of the placement frame 52 and enters the through grooves 58 reserved at both ends inside the storage box 1. These through grooves 58 act as cold air transmission channels, guiding the low-temperature airflow to the upper part of the storage box 1. Then, through multiple sets of through holes 510 distributed on the wall of the through grooves 58, the cold air is evenly diffused into the upper part of the storage box 1, thereby ensuring that the temperature in all corners of the storage box 1 remains consistent.
[0030] The working principle of this stem cell preparation preservation and delivery device will be explained in detail below.
[0031] like Figures 1-6As shown, when using this stem cell preparation preservation and transportation device, initially, the placement plate 29 is located on the upper side of the storage box 1. The operator must carefully fill the test tubes with the stem cell preparation, ensuring the dosage is correct and the test tubes are undamaged. By opening the box cover 3 and pulling the pull plate 218 to one side, the pull plate 218, via the slide rod 217, moves the movable frame 220 and movable seat 221 synchronously, causing the movable seat 221 to move away from the fixed seat 215. At this time, the spring 219 is also compressed, and the test tubes can then be inserted into the sea. In the slot 213 on the pad 212, when the pull plate 218 is released, the spring 219 pushes the movable frame 220 and the movable seat 221 towards the test tube, so that the movable seat 221, in conjunction with the fixed seat 215, can clamp and fix the stem cell reagent test tube to prevent the test tube from colliding. Then the motor 26 can be started, and the motor 26 drives the worm 25 to rotate. The worm 25, through the meshing worm wheel 27, drives the transmission rod 21 to rotate. The transmission rod 21 drives the drum 22 to reverse, so that the suspension rope 23 can be loosened. The placement plate 29 can be slowly lowered into the storage box 1, facilitating the low-temperature storage of the fixed stem cell preparation test tubes and making transportation easier. The transmission rod 21 and the drum 22 rotate forward, thereby winding the suspension rope 23, which can then slowly raise the placement plate 29, allowing staff to directly retrieve the stem cell preparation test tubes. Before using the storage box 1, dry ice can be placed in the placement frame 52, which is then placed into the groove 51 at the lower end of the storage box 1. The clamp 56 is then rotated so that its locking slot 57 aligns with the locking post 54. The clamping mechanism is used to limit the placement frame 52 and the end plate 53, preventing the placement frame 52 from falling off. The cold air generated by the dry ice placed in the placement frame 52 can be directly diffused into the lower end of the storage box 1 through the through hole 7. At this time, the cold air can also be diffused into the through grooves 58 at both ends of the storage box 1 through the strip groove 59. Then, the cold air is diffused into the upper end of the storage box 1 through multiple sets of through holes 510, so that the temperature inside the storage box 1 can be lowered. This allows the stem cell preparation test tubes in the storage box 1 to be placed at low temperature, so as to provide a low temperature environment for the stem cell preparation test tubes.
[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
