A device for controlling the reaction of a microfluidic chip with a camshaft

Abstract

The invention discloses a device for controlling the reaction of a microfluidic chip by using a camshaft. The device uses a camshaft with multiple cams to control multiple links in the reaction process of the microfluidic chip that need to be driven by pressure, such as the time-sharing release and flow control of various liquid reagents in the chip, gas The flow control, as well as the chip locking and other functions that need to be realized by mechanical pressing, the timing of the reaction can be automatically controlled by the curve profile of the cam, the installation sequence, and the rotation speed. The invention provides a feasible technical solution for the miniaturization of the analysis and detection device of the microfluidic chip, making it easier to be commercialized and having wider application prospects.

Description

technical field

[0001] The invention belongs to the field of microfluidic chips, in particular to a device for controlling the reaction of a microfluidic chip with a camshaft. Background technique

[0002] Microfluidic chip, also known as Lab-on-a-chip (Lab-on-a-chip), refers to the integration of basic operating units such as sample preparation, reaction, separation, and detection involved in the fields of biology, chemistry, and medicine into a chip with On the micron-scale microchannel chip, the whole process of reaction and analysis is automatically completed. The advantages of the analysis and detection device based on the microfluidic chip are: the amount of sample used is small, the analysis speed is fast, and it is easy to make a portable instrument, which is very suitable for instant and on-site analysis.

[0003] The core of the analysis and detection device based on the microfluidic chip is the control of the fluid in the microchannel, and pressure drive is one o...
