MICROFLUIDIC CHIP, METHOD FOR CONTROLLING FLOW VELOCITY OF FLUID, AND USE METHOD FOR MICROFLUIDIC CHIP

Document Type and Number:

WIPO Patent Application WO/2023/221124

Kind Code:

A1

Abstract:

A microfluidic chip (1000, 3000, 4000, 5000, 6000), a method for controlling the flow velocity of a fluid in the microfluidic chip (1000, 3000, 4000, 5000, 6000), and a use method for the microfluidic chip (1000, 3000, 4000, 5000, 6000). The microfluidic chip (1000, 3000, 4000, 5000, 6000) comprises at least one flow shunting structure (200, 300, 400, 500, 600); each flow shunting structure (200, 300, 400, 500, 600) comprises at least two flow channels; the at least two flow channels comprise a first flow channel (201, 301, 401, 501, 601) and a second flow channel (202, 302, 402, 502, 602); the first flow channel (201, 301, 401, 501, 601) is configured to allow a first fluid to flow therein, and the second flow channel (202, 302, 402, 502, 602) is configured to allow a second fluid to flow therein; and the first fluid and the second fluid converge at a first convergence point (106) of the microfluidic chip (1000, 3000, 4000, 5000, 6000). The first flow channel (201, 301, 401, 501, 601) has a first cross section (S1) and a first length (L1); the second flow channel (202, 302, 402, 502, 602) has a second cross section (S2) and a second length (L2); the area of the first cross section (S1) is greater than or equal to the area of the second cross section (S2), and the first length (L1) is less than or equal to the second length (L2).
