Title:
MICROFLUIDIC CHIP AND MICROFLUIDIC ANALYSIS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/082229
Kind Code:
A1
Abstract:
The present application is applicable to the field of medical apparatuses, and discloses a microfluidic chip and a microfluidic analysis system. The microfluidic chip comprises a non-circular chip body, wherein a sample injection cavity, a first sample quantification cavity, a diluent intake cavity, a diluent quantification cavity, a mixing cavity, a distribution cavity, a reaction detection cavity, a first overflow cavity and a second overflow cavity are formed in the non-circular chip body; the reaction detection cavity is used for a reagent and a mixed liquid to react to form a sample; the first overflow cavity is in communication with both the diluent quantification cavity and the distribution cavity to collect diluent overflowing from the diluent quantification cavity and collect a mixed liquid overflowing from the distribution cavity; and the second overflow cavity is in communication with the first sample quantification cavity to collect a sample overflowing from the first sample quantification cavity. The microfluidic chip is simple and convenient to use and operate, and can reduce the cost of sample rechecking and the unnecessary waste of samples and consumables.
