  • Patent number: 10761092
    Abstract: Provided is a multi-flux micro-fluidic chip including a chip body. The chip body includes a fluid inflow cavity communicated with an external air path, reaction-quantification cavities, waste liquid cavities, and a fluid path distribution cavity disposed at a middle position of the chip body. The two or more reaction-quantification cavities are distributed on two sides of the fluid path distribution cavity in rows to form the first and second row of reaction-quantification cavities respectively; and they are communicated with a fluid outlet of the fluid path distribution cavity through fluid path branches, and a fluid inlet of the fluid path distribution cavity through fluid path branches, and a fluid inlet of the fluid path distribution cavity is communicated with a fluid outlet of the fluid inflow cavity and an external fluid path, which making it possible to detect multiple items simultaneously and greatly improving the flux of the micro-fluidic chip.

  • Patent number: 10648975
    Abstract: Provided is a single-channel chemiluminescent micro-fluidic chip, including a chip body with a quantification-reaction cavity and a waste liquid cavity. The quantification-reaction cavity is composed of a quantification-reaction pool on a lower portion and a reaction pool cover plate, the quantification-reaction pool is equally divided into three cavities by two partition plates, a labeled antibody is placed in the middle cavity, coated antibodies are placed in the others, a surface, facing the quantification-reaction pool, of the reaction pool cover plate is equally divided into two parts. In result, the coated antibodies and the labeled antibodies are physically separated to effectively avoid nonspecific binding. Due to a special structure of the reaction tank, wavy fluid flow is generated to fully mix the coated antibodies and the labeled antibodies, which improves testing efficiency and sensitivity.
