Patent ID: 8865074

Claim:
A sample analysis cartridge device comprising: an inlet through which a blood sample is introduced; a microfluidic channel connected to the inlet and providing a movement path of the blood sample; a plurality of branch channels connected to the microfluidic channel at a branch point, one of the plurality of branch channels having a bent portion to equalize a length of paths subsequent to the branch point for the blood sample; a projection in the microfluidic channel disposed at a location between the inlet and the branch point, and comprising a vent; a plurality of reaction units respectively formed at the other end of the plurality of branch channels from the branch point and configured to measure a value of a particular component included in the blood sample; a sensing unit positioned in the projection of the microfluidic channel and configured to sense an attribute of the blood sample; and a controller configured to obtain a hematocrit of the blood sample from the sensed attribute of the blood sample, and compensate the measured value of the particular component based on the obtained hematocrit.
