Abstract

A microfluidic detection chip provided by the present invention belongs to the technical field of in vitro diagnosis; it includes a microfluidic chip and a reagent plug; the microfluidic chip includes a sample loading area, a waste liquid area, and a stirring and mixing channel; the upper The sample area includes a quantitative sample inlet hole, a sample loading sufficient amount identification hole, and a sample loading channel. The quantitative sample inlet hole is connected to the sample loading sufficient amount identification hole; the sample loading channel is communicated with the stirring and mixing channel. The stirring and mixing channel is provided with a plurality of reagent holes, and the reagent plug includes a positioning surface, a reagent chamber and a plug body; the reagent chamber is located at the upper end of the plug body, and the positioning surface is located at the lower end of the plug body; The reagent plug corresponds to the position of the reagent hole, and the reagent plug is inserted into the reagent hole. The present invention does not have any liquid reagent components in the microfluidic chip, greatly reducing processing, manufacturing and transportation costs.

Description

technical field [0001] The invention relates to the technical field of in vitro diagnosis, in particular to a microfluidic detection chip and a detection method thereof. Background technique [0002] In the field of in vitro diagnostics, in vitro diagnostic products are mainly composed of diagnostic equipment (instruments) and diagnostic reagents, and for all in vitro diagnostic products, especially those with diagnostic reagents, the design and production of reagent status have always been the responsibility of field products. top priority. For almost all IVD products, the main purpose of the reagents is to provide a uniform liquid-phase reaction environment for the entire biological or chemical reaction system, and at the same time combine the knowledge of biology, chemistry and laboratory medicine to "treat" the target substance in the sample. (For example: staining specific cells, forming immune complexes with specific proteins through immune complexation reactions, etc...
