Abstract: The invention provides a micro fluid device comprising a substrate with a channel forming a receiving cavity, an outer chamber, and an inner chamber, the device further comprising a multi lumen hose with a free end portion which is fixed in the receiving cavity. The multi lumen hose forming a first conduit and at least one second conduit located radially offset from the first conduit, and the outer chamber is in fluid communication with at least one second conduit, and the inner chamber is in fluid communication with the first conduit. The chambers are separated by an inner sealing member located between the substrate and the hose. To simplify the manufacturing of the device, the channel is formed by a groove in an upper surface of a body of the substrate, which groove closed by an essentially plane cover which is sealed to the upper surface.
