Abstract: The utility model relates to a CD disc micro -fluidic chip, including film, reaction detection part, through -hole and a membrane, the through -hole is located micro -fluidic chip's center to be connected with supporting equipment, the reaction detection part is including application of sample hole, liquid storage area, reservation district, reaction hole, ball valve, waste liquid cylinder, exhaust hole, an arc -shaped passageway and the 2nd arc -shaped passageway, an arc -shaped passageway and the 2nd arc -shaped passageway lie in the film, and an arc -shaped passageway connects the reservation district and connects application of sample hole, liquid storage area and reservation and distinguish with exhaust hole, the 2nd arc -shaped passageway, the ball valve is located to be reserved between district and the reaction hole. This CD disc micro -fluidic chip simple structure, convenient to use, and the setting of ball valve has avoided the mutual interference between reagent pollution and each reaction, and its analysis that both can carry out the many indexs of single sample or single index multi -sample also can realize the parallel analysis of the many indexs of multi -sample.
