Fluid treatment method and fluid treatment device

A fluid treatment device, comprising:

• at least one cycle enrichment module;
• wherein the cycle enrichment module comprises:
• an enrichment pipeline, comprising a first section and a second section;
• wherein an entrance of the first section is communicated with at least one first inlet, and an exit of the second section is communicated with the first section;
• at least one first separation module;
• wherein each of the at least one first separation module comprises a first separation component to divide a corresponding first separation module into a first side and a second side;
• wherein two opposite ends of the first side are communicated with the first section and the second section respectively, and the second side is communicated with at least one first outlet;
• and
• at least one first driving device, arranged at the first section, for driving a fluid to cyclically flow in the enrichment pipeline to dynamically balance a total amount of the fluid in the enrichment pipeline, so that the at least one first separation module enriches the target substance in a cycle enrichment mode.

A cycle separation device, for performing fluid treatment, comprising:

• at least one cycle separation module, wherein the cycle separation module comprises:
• a separation pipeline, having an entrance and an exit;
• a second separation module, comprising a second separation component;
• wherein the second separation component divides the second separation module into a first side and a second side;
• wherein two opposite ends of the first side of the second separation module are communicated with at least one second inlet and at least one second outlet respectively, and two opposite ends of the second side of the second separation module are communicated with the entrance of the separation pipeline and the exit of the separation pipeline respectively;
• and
• at least one second driving device, arranged at the separation pipeline, for driving a fluid in the separation pipeline to flow from the entrance of the separation pipeline to the exit of the separation pipeline at a preset flow rate, to dynamically balance a total amount of the fluid in the separation pipeline in a cycle separation mode.

A medical device, comprising:

• a cycle separation device;
• and
• a pipeline system, comprising a fluid-introducing pipeline and a fluid-returning pipeline;
• wherein the fluid treatment device comprises:
• at least one cycle enrichment module;
• wherein the cycle enrichment module comprises:
• an enrichment pipeline, comprising a first section and a second section:
• wherein an entrance of the first section is communicated with at least one first inlet, and an exit of the second section is communicated with the first section;
• at least one first separation module;
• wherein each of the at least one first separation module comprises a first separation component to divide a corresponding first separation module into a first side and a second side;
• wherein two opposite ends of the first side are communicated with the first section and the second section respectively, and the second side is communicated with at least one first outlet;
• and
• at least one first driving device, arranged at the first section, for driving a fluid to cyclically flow in the enrichment pipeline to dynamically balance a total amount of the fluid in the enrichment pipeline, so that the at least one first separation module enriches the target substance in a cycle enrichment mode;
• wherein the cycle separation device is for performing fluid treatment and comprises:
• at least one cycle separation module, wherein the cycle separation module comprises:
• a separation pipeline, having an entrance and an exit;
• a second separation module, comprising a second separation component;
• wherein the second separation component divides the second separation module into a first side and a second side;
• wherein two opposite ends of the first side of the second separation module are communicated with at least one second inlet and at least one second outlet respectively, and two opposite ends of the second side of the second separation module are communicated with the entrance of the separation pipeline and the exit of the separation pipeline respectively;
• and
• at least one second driving device, arranged at the separation pipeline, for driving a fluid in the separation pipeline to flow from the entrance of the separation pipeline to the exit of the separation pipeline at a preset flow rate, to dynamically balance a total amount of the fluid in the separation pipeline in a cycle separation mode.
