<p><P>PROBLEM TO BE SOLVED: To provide a micro fluidic device in which shear force is more effectively generated as compared with the case that the flow directions of two adjacent fluids are not the directions opposite to each other on the boundary between the two adjacent fluids, and to provide a fluid control method. <P>SOLUTION: The micro fluidic device 1 includes: a fluid branch part 10 and a common flow channel 11. The fluid branch part 10 is provided with: a first introduction pipe 2 into which a first fluid is introduced; a second introduction pipe 3 into which a second fluid is introduced and which is disposed adjacently to the first introduction pipe 2; and a plurality of rectification parts 4 each of which is connected to the first and second introduction pipes 2, 3 and used for generating helical flows respectively in the fluids L1, L2 flowing in the first and second introduction pipes. The common flow channel 11 is connected to the fluid branch part 10 and used for merging the first fluid with the second fluid. The rectification part 4 for generating helical flows having the same direction in all of the first and second fluids L1, L2 consists of a rectification plate obtained by layering a plurality of thin film patterns the adjacent ones of which have the positions shifted from each other by a predetermined angle in the circumferential direction. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
