Abstract

The invention discloses a multi-channel microfluidic coagulation detection chip with a five-layer structure. The chip comprises a chip body, the chip body comprises a first layer chip, a second layerchip, a third layer chip, a fourth layer chip and a fifth layer chip from top to bottom in sequence, the first layer chip, the second layer chip, the third layer chip, the fourth layer chip and the fifth layer chip cooperate to define a closed microfluidic channel and a plurality of independent detection chambers, a feeding hole is formed in the first layer chip, and the feeding hole is communicated with the detection chambers through the microfluidic channel; the chip body further includes electrodes, and each of the detection chambers is provided with the electrodes in correspondence. A five-layer chip design can multiply the number of the detection chambers so that more coagulation indexes can be detected at one time, and the detection efficiency is improved. The multi-channel microfluidic coagulation detection chip with the five-layer structure is reasonable in design and simple and compact in structure.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a multi-channel microfluid coagulation detection chip with a five-layer structure. Background technique [0002] Microfluidics is a technology applied across various disciplines including engineering, physics, chemistry, microtechnology and biotechnology. Microfluidics involves the study of small volumes of fluids and how such small quantities of fluids are manipulated, controlled and used in various microfluidic systems and devices, such as microfluidic chips. For example: microfluidic biochips (referred to as "lab-on-a-chip") are used in the field of molecular biology to integrate assay operations for purposes such as analyzing enzymes and DNA, detecting biochemical toxins and pathogens, diagnosing diseases, and the like. [0003] Microfluidic chip (microfluidic chip) is currently a hot field in the development of Miniaturized Total Analysis Systems. The...
