Problems solved by technology
In order to realize the automation and integration of microfluidic chip analysis and detection devices, it is necessary to integrate as many functions of reaction analysis on the chip as possible, and reduce the dependence on off-chip operations. However, microfluidics in related technologies The reagent storage of the control chip is either complex in structure or complex in process, resulting in the high cost of the microfluidic chip as a consumable, and the delivery of reagents cannot be accurately and precisely controlled

The micro-fluidic chip comprises a chip substrate, a chip cover plate and a liquid storage bag, the chip substrate is provided with a preset liquid pool, the top surface of the preset liquid pool is open, the bottom wall of the preset liquid pool is provided with a puncture structure, the chip cover plate is arranged on the top surface of the chip substrate, and the chip cover plate comprises a cover plate body and a control valve plate, the cover plate body is provided with an opening area opposite to the preset liquid pool, the control valve plate is arranged in the opening area and connected with the local edge of the opening area so that the control valve plate can be bent downwards relative to the cover plate body, and the liquid storage bag is fixed to the bottom of the control valve plate and contained in the preset liquid pool. The liquid storage bag can be punctured by the puncturing structure, so that liquid in the liquid storage bag flows into the preset liquid pool. According to the micro-fluidic chip disclosed by the invention, the puncturing mechanism consisting of the control valve plate, the liquid storage bag and the puncturing structure can be adopted to inject a reagent, the puncturing mechanism is simple and easy to implement, and the manual operation time and manual operation errors can be reduced.
Description
Technical field [0001] The present invention relates to the technical field of microfluidic chips, in particular, to a microfluidic chip. Background technique [0002] The microfluidic chip is also called a chip laboratory, refers to the basic operating unit of the sample, reaction, separation, detection involved in the fields of biology, chemistry, and medicine, and other basic operation units with micrometer-scale microchannels, automatic Complete the whole process of reactions and analysis. The advantages of analytical detection devices based on microfluidic chip are: small samples, fast analysis speed, easy to make portable instruments, very suitable for immediate, field analysis, and microfluidic chips are mostly used, so It can be saved liquid path system such as complex cleaning and waste treatment. To achieve the automation and integration of the microfluidic chip analysis detection device, it is necessary to integrate the functions of the reaction analysis to the chip as...
