Abstract
A microfluidic device is configured to sample, meter and collect a metered volume of body fluid for analysis by means of capillary transport. The device comprises: an inlet section, for receiving the body fluid sample, the inlet section comprising an inlet port; a metering section configured to receive body fluid from the inlet section and comprising a metering channel, wherein the metering section is arranged to separate a metered volume of body fluid filled in the metering channel; and an outlet section comprising a cavity between an outlet part of the metering channel and an outlet orifice of the device, a hydrophilic porous bridge element conformable to a shape of the cavity and inserted in the cavity to substantially fill the cavity and the outlet orifice, and a capillary means attached to the outlet section in contact with the hydrophilic porous bridge element.
