[Patent] Microfluidic Device for Detecting Cells of Blood


Abstract:

An microfluidic device includes a substrate (1) having a wandering groove (12) formed on a first surface (11) thereof; a shielding member (2) abutting on the first surface and covering the groove to form a flow channel (101) to deliver blood; an inlet (14) at one end of the flow channel for introducing the blood into the flow channel; and an outlet (16) at another end of the flow channel for discharging the blood. The flow channel (101) has a detecting region (102) for the blood passing through separately, the detecting region includes an entry (1021) for a single cell entering into at a time and an exit (1022) for a single cell exiting out at a time. A pair of electrodes (211) are disposed between the entry (1021) and the exit (1022) to detect the cells (200) of the blood.
