Abstract

The invention discloses a micro flow mixing apparatus and a method thereof. The micro flow mixing method has driving a working flow into a quantitative detection chamber having magnetic particles by a centrifugal force; magnetically attracting magnetic substance away from the quantitative detection chamber by a magnetic conductor; mixing the magnetic particles and the working flow in the quantitative detection chamber by rotating a rotation unit in forward and reverse direction discontinuously; driving the magnetic substance near to the quantitative detection chamber by the magnetic conductor, so as to magnetically attracting the magnetic particles to a side of the quantitative detection chamber; providing a centrifugal force by the rotation unit to let the working flow in a waste liquid area; and monitoring the working flow in the quantitative detection chamber to proceed interpretation of light.

Description

[0001] This application is a divisional application of a patent application with an application date of April 10, 2013, an application number of 201310122365.7, and an invention title of "microfluid mixing device and method thereof". technical field [0002] The invention relates to a microfluid mixing device and a method thereof. Background technique [0003] Microfluidic system, which performs various reactions in each unit to analyze or process a biological sample solution, a sealed disc is used as the microfluidic system today, and the microfluidic system uses a centrifugal force and magnetic particles to perform the desired task. [0004] A target biological material in the biological sample can be combined with the surface functional groups of the magnetic particles to separate the target biological material from the biological sample, and then separate the magnetic particles from the target biological material. [0005] The above-mentioned detection method uses a plu...
