Integrated reaction disc for biochemical analyzer and control method of integrated reaction disc

The invention discloses an integrated reaction disc for a biochemical analyzer and a control method of the integrated reaction disc. A to-be-detected sample storage cavity, a to-be-detected sample quantification cavity, a mixing cavity and a reagent cavity are connected through capillary channels, a diluent storage cavity and a diluent quantification cavity are connected, the mixing cavity and the reagent cavity are connected through capillary channels; each capillary channel is a curve-shaped hydrophobic channel, a specific relationship is formed between the centrifugal radius of each capillary channel and the centrifugal radius of each cavity, and the control method comprises quantitative control, mixing control, liquid preparation control, flushing control and temperature control. Quantitative proportioning, mixing, liquid preparation and early-stage centrifugation functions of a to-be-detected sample and a diluent can be realized only by controlling the reagent disc body to rotate clockwise and anticlockw
