Problems solved by technology

Assuming that the actual concentration of triglycerides in a plasma sample is 180mg / mL, but during the detection process, if 8μL of plasma is injected into the original 6μL detection tank due to errors, the detected triglyceride concentration will be as high as 240mg / mL, and make the original healthy samples be misjudged as high-risk group of cardiovascular disease
In the existing mechanical quantitative methods, most of them use capillarity or wax valves to distribute a large amount of liquid. This method also has the problems of low stability and technical difficulty in making wax valves.
[0008] In view of this, there is still a lack of a low-cost, easy-to-manufacture, high-stability technology.

Abstract

The present invention provides a microfluidic inspection device which comprises a drive module and a microfluidic platform. In the microfluidic inspection device, a rotary unit and a vibration unit of the drive module are used for driving the microfluidic platform, and the microfluidic platform further comprises multiple microfluidic elements for performing tests. The present invention also provides a method for operating a microfluidic inspection device. The method comprises steps using the rotary unit or steps using the vibration unit to distribute sample different regions in a microfluidic structure.

Description

technical field [0001] The present invention relates to a microfluid testing device and its operating method, in particular to a device for delivering quantitative fluid under a centrifugal system and its operating method. Background technique [0002] In traditional testing, sample pretreatment and sample quantification are laborious and cumbersome tasks, requiring large-scale instruments and professionals to obtain samples suitable for testing. These equipment costs and personnel costs have greatly increased the threshold for the establishment of testing departments. Often only research institutions or large hospitals have sufficient capabilities and funds to complete sample testing on their own. On the contrary, small laboratories and clinics in the front line can only entrust professional inspection agencies to obtain reports due to cost. Such a round-trip transportation process will consume a lot of time and cost, and will easily lead to sample deterioration and lower t...
