Perfusion systems and cell cultivation perfusion systems

A cell perfusion cultivation system, comprising a cell incubator, wherein the cell incubator is provided with a perfusion system, the perfusion system including:

• a pressure transfer component, the pressure transfer component including a belt and multiple pressure members disposed on the belt at intervals;
• a driving device, wherein a driving connection is established between the driving device and the pressure transfer component;
• and
• at least one pipeline assembly, the at least one pipeline assembly including at least one pressable pipeline configured for fluid passage;
• wherein a press area is formed between the pressure transfer component and each of the at least one pressable pipeline,
• the multiple pressure members move with the belt, and
• at least a portion of the multiple pressure members press against the at least one pressable pipeline when moving in the press area;
• wherein in the press area, a pressable section of each of the at least one pressable pipeline is simultaneously pressed by adjacent pressure members of the multiple pressure members, thereby forming a blocked fluid section, wherein
• when the at least one pressable pipeline include multiple pressable pipelines, and the at least a portion of the multiple pressure members press the multiple pressable pipelines within the press area, a length of the blocked fluid section of one or more of the multiple pressable pipelines is greater than a distance between the adjacent pressure members.
