Abstract
A multi-channel microfluidic blood coagulation detection chip includes a chip body. The chip body includes a lower-layer chip, a middle-layer chip, and an upper-layer chip in sequence from bottom to top. The lower-layer chip, the middle-layer chip, and the upper-layer chip cooperate with each other to define a closed microfluidic channel and a plurality of mutually-independent detection chambers. The upper-layer chip is provided with a sample loading hole, and the sample loading hole communicates with the detection chambers through the microfluidic channel. The chip body further includes electrodes. The electrodes include upper-layer electrodes and lower-layer electrodes, the upper-layer electrodes are disposed on a back surface of the upper-layer chip, the lower-layer electrodes are disposed on a front surface of the lower-layer chip, and a gap is provided between the upper-layer electrodes and the lower-layer electrodes.
