Description

Technical Field

[0001] The utility model belongs to the technical field of stem cell oscillation, and in particular relates to an oscillator for stem cell amplification. Background Art

[0002] Stem cells are a type of cell with unlimited or immortal self-renewal capabilities and can produce at least one type of highly differentiated daughter cells. In biological cell experiments, stem cells often need to be cultured. Under static culture conditions, stem cells adhere to the bottom bottle wall, and dissolved oxygen and nutrients will form a concentration gradient. Under mild oscillating culture conditions, the concentration gradient is eliminated, the dissolved oxygen concentration is increased, and it is more conducive to growth. Therefore, when amplifying and culturing stem cells, the stem cells need to be oscillated. In order to avoid artificial oscillation, an oscillator is generally used for oscillation.

[0003] Chinese patent application No. 202322029663.3 discloses an oscillator for stem cell amplification, including a base, a docking seat installed at one end of the top of the base, a protective shell installed at one end of the top of the base away from the docking seat, a control panel installed on the outer surface of the protective shell, and a mounting seat installed at one end of the top of the base located inside the protective shell. The utility model designs an oscillator for stem cell amplification. The paddle plate is used to continuously pull the baffle upward and then separate during rotation, so that the oscillation rod rotates back and forth, so that the cell container on the support plate oscillates back and forth within a certain frequency, thereby effectively improving the efficiency of stem cell oscillation, accelerating the amplification and culture process of stem cells, and effectively solving the problem that traditional cell oscillators can only oscillate one stem cell container at a time.

[0004] In the above-mentioned public patent, the arc cover is connected and fixed to the oscillation rod by locking bolts. The bolt connection structure is cumbersome and inconvenient to disassemble and assemble. The motor drives the paddle plate to contact the baffle plate and drive the oscillation rod to rotate and oscillate. Since the distance between the paddle plate and the baffle plate is fixed, the shaking amplitude of the oscillation rod cannot be controlled. Utility Model Content
