Problems solved by technology
[0004] However, a major problem in molecular diagnosis based on centrifugal microfluidics is that the PCR chamber cannot be installed and positioned precisely at one time, especially the position of the PCR chamber on different chips may vary greatly
Therefore, most of them use algorithms to identify the position of the PCR chamber of the chip, which will pre-store a large amount of data to identify the PCR chamber and increase the storage burden of the program software; and each installation will have different errors. After installation, it must be calibrated by software algorithm, increasing repetitive work

The invention relates to a coded disc structure for microfluidic positioning and a microfluidic analysis device. The coded disc structure comprises a coded disc and a positioning device, wherein the coded disc and a chip mounting disc of the microfluidic analysis device rotate synchronously; the coded disc is provided with at least two positioning ports, and each positioning port is used for corresponding to a measuring cavity of the microfluidic analysis device; the positioning device is provided with a receding groove and a positioning position, the coded disc is partially located in the receding groove, a gap exists between the coded disc and the positioning device, and the positioning device is used for positioning when each positioning opening of the coded disc passes through the positioning position. The problem that the position of the measurement cavity of the microfluidic chip needs to be recognized through an algorithm due to the fact that the measurement cavity cannot be accurately installed and positioned at a time is solved, the defect that the measurement cavity is recognized by prestoring a large amount of data is overcome, the coded disc is positioned through a mechanical positioning principle, external coded discs of a temperature zone are in one-to-one correspondence with microfluidic chip measurement cavities such as PCR cavities, and permanent positioning isachieved in the mode that the coded discs are adopted to recognize the measurement cavities.
Description
technical field [0001] The present application relates to the field of centrifugal microfluidics, in particular to a code disc structure for microfluidic positioning and a microfluidic analysis device. Background technique [0002] Microfluidics system refers to a device that manipulates liquids on the submillimeter scale from a few microns to hundreds of microns. It integrates the basic operating units involved in the fields of biology and chemistry, and even integrates the functions of the entire laboratory, including sampling, dilution, reaction, separation, detection, etc., on a small chip, so it is also called Lab-on-a-Chip (Lab-on-a-Chip). -a-Chip). This kind of chip is generally composed of various liquid storage pools and interconnected microchannel networks, which can greatly shorten the sample processing time, and realize the maximum utilization efficiency of reagent consumables through precise control of liquid flow. Microfluidics provides extremely broad prospe...
