Definitions
- the present invention relates to a micromixer and a fluid mixing method.
- a conventional stacked micromixer in which different fluids are divided into two flow paths at approximately the same flow rate ratio and then stacked at a merging portion so that different fluids form a layer is an interface between different fluids. After splitting on a vertical plane, the different fluid layers are stacked in the same direction as the stacking direction of each different fluid layer to form a thin fluid layer, and this process is finally performed with a thickness that is dominant by molecular diffusion. Repeat until it achieves effective mixing.
- Laminated micromixers based on this concept can be found in, for example, Branebjeg et.al, Proc.IEEE—MEMS96, pp441-446, 1996 and Byoung—Gyun et al, Proc.IntSensor Conf 2001, Seoul, Korea, PP.157. — Proposed by 158 et al.

- the cross section of the fluid divided in the vertical direction can be rotated by a predetermined angle with respect to the cross section of the first fluid, and when the fluid divided in the vertical direction is further joined.
- it can be rotated by a predetermined angle again with respect to the cross section of the first fluid. Therefore, through the above process, the first fluid is divided and the cross-section of the divided fluid is rotated by a predetermined angle and then joined, so that the fluid is sufficiently stirred and mixed. Will be.
- the fluid is a multilayer fluid in which different fluids form layers
- the fluid of each layer is divided by the above-described process of the present invention, and the cross section is rotated and then merged.
- the fluids of the respective layers are sufficiently uniformly mixed, and finally, a single-layer fluid in which the fluids are almost uniformly mixed is obtained.
- a fluid having a high specific gravity and a fluid having a low specific gravity including magnetic beads flow through the same flow path, and these fluids are separated based on the specific gravity difference between the fluids to form a multilayer fluid. Even if there is a difference in specific gravity difference as described above, the process of the present invention described above is performed. It becomes possible to sufficiently mix the fluid.

- a micromixer 10 shown in FIG. 1 includes a first plate-like member 11 and an upper portion of the first plate-like member 11 sequentially. Second plate member 12 and fourth plate member 14 provided, and third plate member 13 and fifth plate member 15 provided sequentially below first plate member 11. It contains.
- the first plate-like member 11 is formed with a T-shaped first opening 111 and an I-shaped fourth opening 112, and the ends 111A and 112A of these openings are respectively The first plate-like member 11 is opened at the side ends facing each other.
- the L-shaped second opening 121 is formed in the second plate-shaped member 12, and one end 121 A thereof is the first opening in the first plate-shaped member 11. 111 The upper end of the upper edge 1 1 1 1 B is continuous. Further, the other end 121 B of the second opening 121 is continuous with the front end 112 B of the fourth opening 112 in the first plate member 11.
- the third plate-like member 13 is similarly formed with an L-shaped third opening 131, and one end 131 A thereof is the first opening in the first plate-like member 11. 111 End of upper side opening 111 Continuation with 11C. The other end 131 B of the third opening 131 is continuous with the front end 112 B of the fourth opening 112 in the first plate-like member 11.
- the fourth plate member 14 and the fifth plate member 15 are provided as so-called lids for sealing the first opening 111 to the fourth opening 112, respectively. This is to make the micromixer shown in Fig. 1 function as an actual device.
- FIGS. 2 and 3 are diagrams showing the state of the fluid when flowing in the micromixer 10 shown in FIG.
- the fluid is a multilayer fluid in which two types of fluids having different specific gravities are layered upward and downward will be described.
- the multilayer fluid S1 is introduced into the first opening 111 in the first plate-like member 11 of the micromixer 10. At this time, the multilayer fluid S1 is divided in the left-right direction at the upper side of the first opening 111. Next, the multilayer fluid S1 divided in the left-right direction is continuous with the first opening 111, and the second opening 121 in the second plate member 12 and the second plate 121 in the third plate member 13, respectively. It is introduced into the third opening 131, and as a result, it is divided in the vertical direction. At this time, the multilayer fluid S1 is rotated by 90 degrees with respect to the flow direction, so that the cross section is rotated by 90 degrees.
- the multilayer fluid SI is introduced into the fourth opening 112 of the first plate-like member 11 that is continuous with the second opening 121 and the third opening 131, and is divided in the vertical direction.
- the multilayer fluid S1 joins to become multilayer fluid S2.
- each of the divided multilayer fluids S1 is further rotated by 90 degrees with respect to the flow direction, so that the cross section is rotated by 90 degrees. Therefore, the multilayer fluid S2 rotates 180 degrees in cross section with respect to the previous multilayer fluid S1, and the stacking order of the fluid constituting each layer is reversed, and the number of layers is doubled.
- the multilayer fluid S1 is divided in the cross-sectional direction by passing through the micromixer 10 shown in FIG. 1, and the cross-section itself is rotated 180 degrees.
- each layer is more mixed and uniform than the multilayer fluid S 1.

- a plurality of micromixers 10 as shown in FIG. 1 are connected in series, and the multilayer fluid S1 is continuously passed through the plurality of micromixers, so that the multilayer fluid S1 is connected to each microfluidic fluid. Since the mixing operation as described above is performed in the mixer and uniform mixing is performed, the degree of uniform mixing of the finally obtained multilayer fluid S2 is further improved.
- the corner portion can be chamfered in at least one of the third openings 131 provided in the three plate-like members 13. If there are sharp corners in these openings, the flow rate decreases in the corners when the multilayer fluid S1 flows through those openings, so that the multilayer fluid S1 is sufficiently mixed. It may not be possible. Therefore, in order to suppress the occurrence of these problems, it is preferable to chamfer the corners of the opening as described above.
- each plate-like member can form any material force, but as long as the above-described fluid mixing method of the present invention can be realized, a force such as a resin, metal, glass, etc. can be formed. . Therefore, preparation of each plate-like member and processing for each plate-like member are easy. Thus, the above-described opening, that is, the formation of the micromixer itself can be easily performed.

- the present invention is not limited to the above-described contents, as long as it does not depart from the scope of the present invention. All modifications and changes are possible.
- the force described in the case of mixing a multilayer fluid can be applied not only to a multilayer fluid but also to a single-layer fluid, and the yarn formation and concentration in the fluid are more uniform. Can be mixed.
- the multilayer fluid S1 passes through the fourth opening 112, the second opening 121, and the third opening 131, and then the first opening. It can be made to flow backward toward 111.
- the multilayer fluid S1 divides the multilayer fluid S1 upward at the second opening 121, divides the multilayer fluid S1 downward at the third opening 131, and upwards at the first opening 111.
