[0002] The stem cell preservation ice bag is a low-temperature preservation container specially designed for stem cells and other biological samples, which mainly provides a stable low-temperature environment to maintain the activity of stem cells, prolong the preservation time, and ensure the safety of the samples during transportation and storage. It is designed with a specific shape and size to adapt to different sizes and types of stem cell storage containers.

[0003] When the stem cell preservation ice bag stores and transports stem cells, it basically stores stem cells through a single ice bag. However, the refrigeration effect of a single ice bag is not good, and the insulation effect of the ice bag will deteriorate after a long time of storage, reducing the storage practicability of the ice bag.

[0004] To overcome the above-mentioned defects, the prior art 1 (Chinese patent with application number CN202120938740.5 and application date of 2021-05-06) provides a stem cell preservation device, which can conveniently store reagent tubes, store more reagent tubes at a time, improve the use effect, and effectively insulate the reagent tubes to store them in a low-temperature state. The device can also add a filling ice bag to ensure the refrigeration effect, ensure the stem cell preservation environment, and prolong the stem cell preservation time. The device is small and easy to place and transport.

[0005] Although the prior art can improve the refrigeration and storage effect of the ice bag and make it more convenient to store and transport stem cells later, it basically carries and transports the ice bag by placing it when storing and transporting stem cells in the ice bag. There is no hanging mechanism to carry and transport the transported ice bag, which can cause the stem cells in the ice bag to shake and become unstable, reducing the transportation efficiency of the ice bag.

[0006] Therefore, we propose a stem cell preservation ice bag that can effectively solve the above problems. UTILITY MODEL CONTENTS

[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] This utility model provides the following technical solution:

[0032] Example 1 addresses the problem that existing methods of transporting stem cells using a bag 1 primarily involve placing the bag 1 on its surface without a suspension mechanism, leading to instability and reduced transport efficiency. The following method is disclosed:

[0033] The bag body 1 and the side pockets 2, wherein the two side pockets 2 are located on both sides of the bag body 1, and the two side pockets 2 are symmetrically arranged about the vertical center line of the bag body 1;

[0034] The top two sides of the bag body 1 are symmetrically provided with slots, and the top two sides of the bag body 1 are fitted with positioning plates 4 by screws, and the outer ends of the two positioning plates 4 extend through the two slots to the top two sides of the bag body 1.

[0035] Hook 6 has an arc-shaped top and a fixed frame 5 rotatably connected to the bottom of hook 6 via a movable shaft.

[0036] The bottom ends of the fixing frame 5 are connected to the positioning plate 4 by screws, and the width of the fixing frame 5 is greater than the width of the bag body 1.

[0037] The inner end of the hook 6 is slotted to install the drive shaft 8, and the outer side of the drive shaft 8 is rotatably connected to the limit rod 7, which is inclined.

[0038] The outer end of the limiting rod 7 is attached to the inner wall of the hook 6.

[0039] A torsion spring 9 is wound around the outside of the drive shaft 8, and a limit rod 7 is connected to the outside of the torsion spring 9.

[0040] like Figures 1-3 As shown, when it is necessary to transport the stem cells stored in the bag 1, simply hang the hook 6 at the top of the bag 1 on the hanging rod to suspend the bag 1. At this time, the fixing frame 5 at the bottom of the hook 6 can open the bag 1, avoiding the deformation of the bag 1 during transportation and improving the practicality of the bag 1 for transporting stem cells.

[0041] Before hook 6 is hung on the suspension rod, manually press the limiting rod 7 to make it flip and swing, so that the limiting rod 7 is not in contact with hook 6. Then hang hook 6 on the suspension rod and release the limiting rod 7. Then the torsion spring 9 will use its own elastic force to elastically reset the limiting rod 7 after it has been squeezed and flipped, so that the limiting rod 7 is in contact with the inner wall of hook 6, thus limiting the suspension of hook 6 and preventing the bag 1 from loosening and falling off due to shaking during the subsequent suspension and transportation, thereby improving the transportation stability of bag 1.

[0042] Example 2 differs from Example 1 in that it utilizes two side bags 2 to cool and store the bag body 1, thereby extending the storage time of stem cells and improving its practicality. The following is disclosed:

[0043] The two side pockets 2 have symmetrically opened placement slots 10 inside, and ice blocks from the outside are placed inside the two placement slots 10, and insulation pads 3 are placed on the outside of the two placement slots 10 respectively.

[0044] The outer sides of the two side pockets 2 are sewn together with a first Velcro 11, and the outer side of the first Velcro 11 is corresponding to a second Velcro 12, and the second Velcro 12 is sewn onto the inner side of the two insulation pads 3.

[0045] like Figures 1-6 As shown, when storing and transporting stem cells in bag 1, external ice is placed inside the two side bags 2 through two placement slots 10. The ice inside the two side bags 2 can increase the storage time of stem cells inside bag 1 and improve the transportation efficiency of bag 1. Finally, the two insulation pads 3 are attached to the first Velcro 11 on the outside of the two side bags 2 by the second Velcro 12 to fix the two insulation pads 3 in place. Thus, the two insulation pads 3 can keep the ice inside the side bags 2 warm, thereby improving the storage efficiency of stem cells.
