Title:
MICROFLUIDIC CHIP FOR SEPARATING AND DETECTING WHOLE BLOOD SAMPLE AND DETECTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/184382
Kind Code:
A1
Abstract:
Provided is a microfluidic chip for separating and detecting whole blood samples, comprising a chip body provided with a sample flow channel. The sample flow channel comprises a sample injection zone, a sedimentation zone, a mixing zone, a detection zone and a waste liquid zone connected in sequence. The sedimentation zone comprises a sample injection portion and a sedimentation portion, and the ratio of the maximum width of the sedimentation portion to the maximum width of the sample injection portion is 2-10. The sedimentation portion is a structure with two narrow sides and a wide width in the middle. The front and rear side walls of the two ends of the sedimentation portion are all inclined surfaces, and the extension lines of the front and rear side walls intersect to form an angle. The front and rear side walls of the middle portion of the sedimentation portion are parallel faces parallel to each other. The microfluidic chip can combine the separation and detection of plasma in whole blood, and does not require complicated whole blood sample pretreatment process, and can quickly and quantitatively detect single or multiple proteins or other indicators in whole blood.
