Micro -fluidic device of paper base

The utility model discloses a micro -fluidic device of paper base for reduce the sample number of times in the micro -fluidic device of paper base testing process, its characterized in that: the edge in hydrophilic district is equipped with hydrophobic border one number, the center in hydrophilic district is equipped with the application of sample round hole, the outer fringe intercommunication of application of sample round hole has the capillary passageway of a plurality of circumference arrays, and is a plurality of the outer end of capillary passageway all communicates there is the inspection hole. The utility model discloses an every capillary passageway has communicating length and width, and the size of every inspection hole is also the same moreover, and when consequently placing the test paper level, the appearance fluid content theory in every inspection hole is the same, adds different fluorescence probes in different inspection holes, reaches and detects multiple composition or ionic purpose, real
