Abstract
A multi-channel microfluidic blood coagulation detection chip having a five-layer structure includes a chip body. The chip body includes, in sequence from top to bottom, a first-layer chip, a second-layer chip, a third-layer chip, a fourth-layer chip, and a fifth-layer chip. The first-layer chip (1), the second-layer chip, the third-layer chip, the fourth-layer chip, and the fifth-layer chip cooperate with each other to define a closed microfluidic channel and a plurality of mutually-independent detection chambers. The first-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, and the electrodes are disposed within the detection chambers in one-to-one correspondence.
