  • Microfluidic chip capable of finely adjusting coaxial alignment of capillary tubes
    Patent number: 11975323
    Abstract: A microfluidic chip includes an integrated chip support (1), a continuous phase liquid inlet (1-6), an intermediate phase liquid inlet (1-7), a dispersed phase liquid inlet (2), an injection capillary tube (3), a collection capillary tube (4), a collection port (5), capillary tube nesting assemblies (6) and capillary tube coaxial fine adjustment assemblies (7). The chip support (1) is provided with threaded holes (1-1), sealing holes (1-2), capillary tube coaxial alignment holes (1-3), adjusting holes (1-4) and positioning holes (1-5). The injection capillary tube (3) and the collection capillary tube (4) present a three-dimensional coaxial alignment under the combined adjustment of the adjusting holes (1-4) and the capillary tube coaxial fine adjustment assemblies (7), and the capillary tube nesting assemblies (6) can realize the fixing and sealing of the capillary tubes in the chip support (1).
