Description

Technical Field

[0001] The utility model relates to the technical field of stem cell storage, in particular to a stem cell storage rack. Background Art

[0002] Stem cells are a type of multipotent cells with the ability to self-renew. Under certain conditions, they can differentiate into a variety of APSC multipotent cells. They are a type of primitive cells with the potential for self-replication and multidirectional differentiation, that is, stem cells remain in an undirected differentiation state and have the ability to proliferate. Under appropriate conditions or given appropriate signals, they can differentiate into a variety of functional cells or tissues and organs. Stem cells come from embryos, fetal tissues, and adult tissues. Embryonic stem cells from embryonic and fetal tissues have multipotential differentiation characteristics and can differentiate into almost all of the more than 200 mature cell types in mature individuals. Adult stem cells from adult individual tissues include hematopoietic stem cells, neural stem cells, and pancreatic stem cells.

[0003] When stem cells are used for medical treatment or research, they usually need to be transported. Existing storage devices usually have a single structure and cannot well ensure that the stem cells are in a constant temperature environment during the transportation process. In addition, if collision or vibration occurs during the transportation process, it is very likely to affect the stem cells, resulting in a decrease or loss of the activity of the stem cells. Therefore, a stem cell storage rack is proposed. Utility Model Content

The upper refrigerant storage layer 4 and the lower refrigerant storage layer 5 are used as cold sources, and the cold air inside them is delivered to the interior of the cabinet 1 through the cold air delivery pipe 6, so that the interior of the cabinet 1 maintains a constant temperature environment to avoid affecting the activity of stem cells due to temperature changes.

[0025] like Figure 2 as well as Figure 3 As shown, the mounting mechanism 8 is one of the core components of the stem cell storage rack, and is mainly used for mounting and fixing the storage device 8 and providing a buffering effect. The mounting mechanism 7 includes: a base 71 arranged inside the cabinet 1, connecting rods 72 arranged on both sides of the base 71, a reinforcing rod 73 arranged on the connecting rod 72, and a buffer sleeve 74 arranged on both sides of the inner wall of the cabinet 1.

[0027] A spring is provided inside the buffer sleeve 74, and the spring is placed between the buffer sleeve 74 and the connecting rod 72. When the device receives an impact force, the connecting rod 72 will push the spring to compress, and the elastic force of the spring will offset the impact force received by the storage device 8, thereby preventing the activity of stem cells from being damaged due to external impact.

[0028] like Figure 4 as well as Figure 5 As shown, the storage device 8 is another core component of the stem cell storage rack. The storage device 8 is mainly used for storing stem cells.

Different storage units are adapted to different sizes of stem cell storage containers. The purpose of this design is to adapt to stem cell storage containers of different diameters according to actual needs.

[0029] A turntable 86 is provided inside the base 71 , the bottom end of the turntable 86 is fixedly connected to the base 71 , the top end of the turntable 86 is fixedly connected to the bottom surface of the storage tray 81 , and the storage tray 81 is rotatably connected to the base 71 via the turntable 86 .

[0030] As mentioned above, by rotating the storage disk 81, different storage units can be rotated to the front of the user to facilitate the storage and removal of stem cell storage containers.

[0031] At the same time, in order to better protect the stem cells, a sealing cover 9 is provided on the base 71 , and the sealing cover 9 is threadedly connected to the base 71 .

[0032] In summary, compared with existing storage devices, the utility model can provide cold air through the upper refrigerant storage layer 4 and the lower refrigerant storage layer 5 when storing and transporting stem cells, and cool the cabinet 1 through the cold air delivery pipe 6, so as to ensure that the interior of the cabinet 1 maintains a stable constant temperature environment. The utility model can also provide a buffering effect on the stem cell storage device 8 during transportation to prevent the stem cell storage container from being impacted or collided, which affects the activity of the stem cells. At the same time, the stem cell storage device 8 in the utility model can also adapt to stem cell storage containers of different sizes, such as test tubes of different diameters, which is more convenient for the storage of stem cells.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
