Description

Technical Field

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

[0002] Stem cells are a type of cell with unlimited or immortal self-renewal ability and can produce at least one type of highly differentiated progeny cells. In adult organs, stem cells can repair tissues by continuously dividing, or remain dormant like in mammalian brain tissue. Stem cell cultivation is often required in biopharmaceuticals and biological experiments.

[0003] The existing technology has the following deficiencies: The prior art, "A layered stem cell cultivation device" with publication number CN217418665U, "comprises an outer box and an inner box, wherein a plurality of first damping columns are fixedly mounted on the lower surface of the inner portion of the outer box, and a plurality of second damping columns are fixedly mounted on two opposing surfaces of the inner portion of the outer box, wherein the inner box is fixedly mounted on the upper surface of the first damping columns, and the top ends of the second damping columns are connected to the inner box, thereby reducing the impact on the inner box by the first and second damping columns."

[0004] When the above-mentioned equipment is in use, an outer box, a first damping column, a second damping column and an inner box are arranged so that the inner box is installed between the damping columns when the device is in use. When the outer box is subjected to shocks such as vibration, the kinetic energy of the inner box will be absorbed by the damping columns to slow down the shaking amplitude, thereby protecting the culture dish inside. External objects cannot directly touch the inner box, preventing them from being accidentally damaged, and the protection effect is good. However, during cultivation, since the culture dishes required for cultivation are of different sizes and occupy different spaces, the fixed-design partitions are not convenient for dividing the internal storage space, which is not conducive to the layered placement of items.
