Abstract

A microfluidic chip with a rotary valve structure includes a valve core, a substrate and a base plate, one surface of the substrate is attached to the base plate, the other surface of the substrate is provided with a valve chamber and a flow passage, the valve chamber is provided with at least two valve chamber through holes, each valve chamber through hole is respectively connected with the flow passage, the substrate is also provided with an inlet and an outlet respectively connected the flow passage, the valve core comprises a sealing layer and a support layer, the sealing layer is arranged in the valve chamber, the support layer is arranged on the sealing layer, the sealing layer is provided with a switching channel; and the support layer rotates to drive the rotation of the sealing layer for communication of the switching channel with the at least two valve chamber through holes. Free conversion and opening and closing of different flow paths can be realized only by use of one valve core, the control requirements of various flow paths can be met, production efficiency is improved; the control of the flow paths can be realized only by rotating of the valve core, and the control method is simple and efficient.

Description

technical field

[0001] The invention relates to the technical field of nucleic acid amplification and detection, in particular to a microfluidic chip with a rotary valve structure. Background technique

[0002] Microfluidic chip is based on micro-electromechanical processing technology, which forms a network on the chip by micro-pipelines, and runs through the entire system with controllable micro-fluidic channels to complete various biological and chemical processes. In the early stage of the development of microfluidic chip technology, chip capillary electrophoresis was the mainstream technology, and the chip used was simple in structure and single in function; Important biological and chemical processes such as reaction and cell lysis have become new hotspots. With the development of the industry, the technical application of microfluidic chips has entered the stage of clinical application, involving complex processes such as reagent mixing, reaction, and pretreatment. ...
