Claim Text:
1. A microfluidic flow analyzer for pathological detection comprising: plurality of buffer channels, wherein each of the plurality of buffer channels carries buffer solution; a sample channel to carry sample solution; a central flow channel configured to receive the buffer solution and the sample solution, wherein the plurality of buffer channels and the sample channel are converged at entry side of the central flow channel to form narrow path in the central flow channel for the sample solution to flow in the central flow channel; plurality of first exciting optical channels placed orthogonally to the central flow channel, wherein each of the plurality of first exciting optical channels is coupled with a first set of fibre coupled laser source to excite cells in the sample solution, flowing through the central flow channel, to produce one or more first optical signals; plurality of first receiving optical channels, wherein each of the plurality of first receiving optical channels is placed at a predetermined angle to optical axis of each of the plurality of first exciting optical channels respectively, to receive one of the one or more first optical signals; plurality of first detectors, wherein each of the plurality of first detectors is placed on each of the first receiving optical channel to detect at least one of the one or more first optical signals; one or more second exciting optical channels, wherein each of the one or more second exciting optical channels is placed at a predetermined angle to the central flow channel, each of the one or more second exciting optical channels is coupled with a second set of fibre coupled laser source to excite the cells in the sample solution, flowing through the central flow channel, to produce one or more second optical signals; one or more second receiving optical channels, wherein each of the one or more second receiving optical channels is placed at a predetermined angle to the central flow channel to receive one of the one or more second optical signals; and one or more second detectors, wherein each of the one or more second detectors is placed on each of the one or more second receiving optical channels to detect at least one of the one or more second optical signals.
