Title:
マイクロ流体制御血液型検出チップ
Document Type and Number:
Japanese Patent JP7399518
Kind Code:
B2
Abstract:
The invention discloses a microfluidic blood type detection chip. The chip comprises a chip body (2), and the chip body (2) comprises: a forward typing blood type identification area, which is provided with a first sample injection chamber (41), a quantitative mixing chamber (8), a forward typing reaction chamber, and a vent hole; a reverse typing blood type identification area, which is provided with a second sample injection chamber (42), a quantitative separation chamber, a reverse typing reaction chamber, and a vent hole; a sample is injected into the first sample injection chamber (41), from which the sample and preset diluent flow into the quantitative mixing chamber (8) through a microfluidic channel; after the sample and the diluent are mixed in the quantitative mixing chamber (8), they enter the forward typing reaction chamber to react with a reaction reagent for detection; a sample is injected into the second sample injection chamber, and enters the quantitative separation chamber through a microfluidic channel, the sample is separated in the quantitative separation chamber, and separated plasma enters the reverse typing reaction chamber and reacts with a reaction reagent for detection. The present invention can realize the simultaneous forward and reverse typing blood type identification, so that the results of blood type identification are more accurate.
