The invention discloses a multi-index 
disease combined detection microfluidic device, which comprises a microfluidic reaction 
chip, a microfluidic storage 
chip, a 
direct current motor driving module,a reaction 
chip fluid control module, a storage release 
fluid control module, a 
temperature control module, and a CCD detection module. Through the cooperation between the reaction chip fluid controlmodule, the storage release 
fluid control module, the 
temperature control module, and the microfluidic reaction chip, a sample and a sample diluting solution are mixed; 
microsphere surface coated antibodies capture target 
cell specific antigens, non-specific adsorbed 
cell antigens on the 
microsphere surface are washed off, target 
cell antigens specifically absorbed on the 
microsphere surface capture 
enzyme labeled antibodies, exciting liquids (A and B) are mixed, enzymes specifically adsorbed on the microsphere surface catalyze the 
chemiluminescence of the exciting liquids; the CCD detection module detects and collects the 
chemiluminescence signals of the microsphere surface, and multiple index antigens in a serum sample are captured and detected automatically.
