Microfluidic devices

Abstract

A method of manufacturing an outlet section of a microfluidic device configured to sample, meter and collect a metered volume of body fluid for analysis by means of capillary transport; the method comprising: providing a microfluidic device having an outlet section in fluid communication with a metering section comprising a metering channel configured to receive body fluid from an inlet section with an inlet port, wherein the outlet section comprises a cavity between an outlet part of the metering channel and an outlet orifice of the device; providing a hydrophilic porous bridge element arranged to conform to the shape of the cavity; inserting the bridge element into the cavity, such that the bridge element substantially fills the cavity and the outlet orifice; and attaching a capillary means to the outlet section, thereby establishing contact between the capillary means and the bridge element.
