Abstract

The embodiment of the invention provides a hydraulic switch valve for a micro-fluidic chip and the micro-fluidic chip. The hydraulic switch valve comprises a plate body and an ejector rod, the plate body is provided with at least one hollow part used for containing liquid, and the hollow part penetrates through the plate body and is provided with a first opening end and a second opening end; and a first thin film is arranged at the first opening end, a second thin film is arranged at the second opening end, the first thin film and the second thin film are used for sealing the hollow part, and the ejector rod applies pressure to the first thin film to enable the second thin film to deform so as to block a preset position of a micro-channel in the micro-fluidic chip. Compared with an existing air pressure valve, the hydraulic switch valve formed through the liquid force conduction property can directly control on-off of the micro-channel in the micro-fluidic chip, meanwhile, the requirement for leakproofness between the valve body and the chip is reduced, and on-off control over multiple micro-channels or multiple positions in one micro-channel is facilitated.

Description

technical field [0001] The disclosure relates to the field of biological instruments, in particular to a hydraulic switching valve for a microfluidic chip and a microfluidic chip. Background technique [0002] In recent years, the rise and integration of various new technologies and methods have promoted the development, application and replacement of in vitro diagnostic (IVD) instruments and reagents. Microfluidic chips can integrate a series of basic operating units involved in the fields of chemistry and biology, such as sample preparation, reaction, separation, and detection, into a micron-sized chip. At the same time, the network formed based on microchannels can run through the entire system. , has the advantages of portability, low energy consumption, easy production, easy to master, etc., and is easy to meet the needs of life sciences for low-dose, more efficient, high-sensitivity, and rapid separation and analysis of biological samples. However, in the current use ...
