Description

technical field [0001] The invention relates to the field of centrifugal analyzers, in particular to a centrifugal portable microfluidic analysis device and a method for using the same. Background technique [0002] Clinical biochemistry and immune tests are routine physical examination items, which are of great significance to the prevention, diagnosis and treatment of diseases. In use, biochemical and immunological tests are often completed by fully (semi) automatic biochemical and immunological analyzers, and real-time testing can greatly reduce the turnaround time from samples to test results and improve efficiency. [0003] At present, some systems based on disposable cartridges or disposable microfluidic chips can realize instant testing of biochemical indicators. For example, blood in fingertip capillaries can be collected at home for instant testing of blood glucose. However, for most users, only monitoring one indicator of blood sugar cannot achieve the purpose of ...

AI Technical Summary

Problems solved by technology

However, the main problem of the current centrifugal microfluidic analysis system is that the existing equipment is usually dedicated, desktop, and non-portable, and lacks versatility

For example, the liquid sampling, quantification, separation, mixing and other operations in different testing items are usually determined by the structural design of the microfluidic chip. Different testing items and different testing sample types involve speed control, tray structure, temperature control curve, testing The location and other items are different. According to the existing similar technology, customized and pre-burned firmware solutions are often used, which is not compatible with different testing items, and the instrument cannot be remotely updated after sales.
