Description

Technical Field

[0001] This utility model relates to the field of stem cells, and in particular to a stem cell storage and transport device. Background Technology

[0002] Stem cells are a type of cell with self-renewal capacity and multi-directional differentiation potential. They can maintain the stability of their own cell population through cell division, and under certain conditions, they can differentiate into many different types of cells, such as nerve cells, cardiomyocytes, and blood cells.

[0003] In existing technologies, there are various methods for short-distance transport of stem cells. Special refrigerated transport boxes are often used. After collection, the stem cells are placed in culture tubes containing culture medium and then placed on a shelf inside the refrigerated transport box. The refrigerated transport box maintains a low-temperature environment to ensure the activity of the stem cells and keep them in a stable state during transport. At the same time, there are cushioning materials inside the box to prevent physical damage to the stem cells caused by transportation bumps.

[0004] Traditional transport devices typically have a fixed, layered shelf structure. After transport, operators need to switch between shelves of different heights to place or retrieve culture tubes one by one. This method is not only time-consuming but also requires a lot of effort from the operators. In particular, when processing culture tubes in batches, the work efficiency is extremely low. Therefore, a stem cell storage and transport device is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0030] 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.

[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a stem cell storage and transport device, including a refrigerated carrying case 1. The refrigerated carrying case 1 has an extension mechanism 2 and an unfolding mechanism 3 inside. The extension mechanism 2 includes a support base 211, the bottom of which is slidably connected to the bottom of the inner wall of the refrigerated carrying case 1. A groove is formed at the top of the support base 211, and a limiting telescopic rod 212 is fixedly connected to the inner wall of the groove. The limiting telescopic rod 212 can limit the movement of the first shelf 213 during its lifting and lowering process, ensuring its smooth movement. The top of the inner rod of the limiting telescopic rod 212 is fixedly connected to the first shelf 213, which is used to place culture tubes containing stem cells. A hinge rod 214 is hinged to the outer wall of the support base 211. When the second shelf 218 is pulled, the hinge rod 214 can drive the second hinge rod 215 to move synchronously. A hinge rod 215 is fixedly connected to the bottom end. The hinge rod 215, through its hinge with the hinge rod 3 216, pushes the frame plate 213 to move up and down. The top of the hinge rod 215 is hinged to the hinge rod 3 216. The upper and lower ends of the hinge rod 3 216 are respectively hinged to the frame plate 213 and the hinge rod 215, thereby realizing the lifting and lowering of the frame plate 213. The top of the hinge rod 3 216 is hinged to the outer wall of the frame plate 213. The outer wall of the support base 211 is hinged to the hinge rod 4 217. When the frame plate 218 is pulled, the hinge rod 4 217, in conjunction with the hinge rod 1 214, makes the two frame plates 218 and their bottom hinge points move away from each other. The top of the hinge rod 4 217 is hinged to the frame plate 218. The frame plate 218 is used to place culture tubes containing stem cells and can cooperate with the frame plate 213 to facilitate the batch placement or removal of culture tubes.

[0032] Reference Figure 1 , Figure 4 The exhibition mechanism 3 includes a sealed door 311, the bottom of which is hinged to the outer wall of the refrigerated container 1, and the top of which is snapped onto the outer wall of the refrigerated container 1. The exhibition mechanism 3 also includes a hinge rod 312, one end of which is hinged to the outer wall of the sealed door 311. When the sealed door 311 is opened, the hinge rod 312 moves accordingly, thereby pulling the slider 315. The exhibition mechanism 3 also includes a connecting rod 313, the outer wall of which is rotatably connected to the inner wall of the other end of the hinge rod 312. The connecting rod 313 is used to connect the hinge rod 312 with the slider 315 and the connecting block 316.

[0033] Reference Figure 1 , Figure 4The exhibition mechanism 3 also includes a slide 314, which is located on the left and right sides of the inner wall of the refrigerated container 1, providing a sliding track for the slider 315. The outer wall of the slider 315 is slidably connected to the inner wall of the slide 314. The slider 315 slides in the slide 314 under the pull of the hinge rod 312, which drives the connecting block 316 and the support base 211 to be displayed. One side of the slider 315 is fixedly connected to one end of the connecting rod 313. The exhibition mechanism 3 also includes a connecting block 316, whose outer wall is fixedly connected to the back of the support base 211. The connecting block 316 moves under the action of the slider 315, thereby driving the support base 211 to move. The outer wall of the connecting block 316 is fixedly connected to the other end of the connecting rod 313. The exhibition mechanism 3 also includes a handle 317, whose outer wall is fixedly connected to the outer wall of the sealed door 311, making it convenient for operators to open the sealed door 311.

[0034] Working principle: During short-distance stem cell transport, the collected stem cells are placed into a culture tube containing culture medium. Then, the hinged sealed door 311 on the outer wall of the refrigerated container 1 can be opened via handle 317. When the sealed door 311 opens, it moves the hinge rod 312 on the outer wall of the sealed door 311. When the sealed door 311 rotates 90 degrees around its hinge point, the hinge rod 312 on the outer wall of the sealed door 311 moves along with the sealed door 311. This causes the end of the hinge rod 312 away from the sealed door 311 to pull the slider 315 in the groove 314. The inner wall slides, simultaneously causing the connecting block 316 and the support base 211 to be displayed, thereby allowing shelf one 213 and shelf two 218 to be displayed. This facilitates the subsequent placement of culture tubes containing stem cells on the inner wall of the placement slots opened at the top of shelf one 213 and shelf two 218, clearly displaying the placement area originally located inside the refrigerated container 1. This makes it easy to quickly find a suitable position to place or retrieve the culture tubes, eliminating the need for operators to reach into the limited space inside the refrigerated container 1 to operate, avoiding inconvenience caused by space constraints, and reducing the risk of knocking over or damaging other culture tubes.

[0035] When frame 1 (213) and frame 2 (218) are fully extended, frame 2 (218) can be pulled by both hands, causing the two frames 2 (218) to move away from each other at the hinge points at the bottom ends of hinge rod 1 (214) and hinge rod 4 (217). When hinge rod 1 (214) moves, it can simultaneously drive hinge rod 2 (215) fixedly connected to the outer wall to move synchronously. Through the hinge action of hinge rod 3 (216) at its upper and lower ends respectively with frame 1 (213) and hinge rod 2 (215), hinge rod 2 (215) moves through the hinge rod... The third 216 pushes the first shelf 213 up and down. The limiting telescopic rod 212 can limit the movement of the first shelf 213 during its lifting and lowering. Finally, the two second shelves 218 are located on the left and right sides of the first shelf 213, which makes it easy to place multiple culture tubes on the inner wall of the placement slot at the top of the first shelf 213 and the second shelf 218. Operators can conveniently place or retrieve culture tubes in batches without having to switch back and forth between shelves at different heights, saving time and effort and greatly improving work efficiency.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
