Abstract

The invention provides a microfluidic detection device which comprises a rack, a centrifugal module, an automatic card loading module, an automatic card unloading module, a card loading station, a card unloading station, a waiting station corresponding to the card loading station, and a guide channel arranged between the waiting station and the card loading station, the automatic card feeding module comprises a card pushing piece and a first driving mechanism, the output end of the first driving mechanism is connected with the card pushing piece, and the card pushing piece is in surface contact with the micro-fluidic chip in the card pushing process, so that the stressed area is large, and the card can be stably and accurately pushed; the pushing force is large, so that in the process of stably pushing the micro-fluidic chip, the reaction cavity can be pushed to be close to the puncture structure, and automatic puncture is realized.

Description

technical field [0001] The invention relates to the field of microfluidic technology, in particular to a microfluidic detection device. Background technique [0002] Microfluidics refers to the science and technology involved in the use of micropipes (tens to hundreds of microns in size) to process or manipulate tiny fluids (nanoliters to attoliters in volume) and is a discipline involving chemistry, fluid physics , microelectronics, new materials, emerging interdisciplinary disciplines of biology and biomedical engineering. Because of the characteristics of miniaturization and integration, microfluidic devices are often called microfluidic chips. [0003] Centrifugal microfluidic technology integrates each reaction unit on a rotatable microfluidic chip through a structure such as a micropipe, and drives the liquid with centrifugal force, thereby completing the complex operation and reaction process of the liquid on the microfluidic chip, realizing various A technique for ...
