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.

Claim (Index 2):
The single-channel chemiluminescent micro-fluidic chip according to  claim 1 , wherein the fluid outlet of the whole blood filter cavity is communicated with the fluid inlet of the quantification-reaction cavity through a first anti-backflow device, and a fluid outlet of the cleaning solution delivery branch and a fluid outlet of the chromogenic reagent delivery branch are converged and then communicated with the fluid inlet of the quantification-reaction pool through a second anti-backflow device; the first anti-backflow device and the second anti-backflow device are of the same structure and each includes an anti-backflow structure located above the micro-fluidic passage and provided with an anti-backflow passage for increasing a liquid level of the micro-fluidic passage at an anti-backflow structure mounting position; and when the micro-fluidic passage is communicated with the external air path, fluid in the micro-fluidic passage through both sides of each said anti-backflow device is driven by air from the external air path to circulate by overcoming a pressure generated by the liquid level, increased by the corresponding anti-backflow passage at the corresponding anti-backflow structure mounting position, of the micro-fluidic passage.
