Abstract (en)
[origin: WO2005016534A1] The invention relates to a microdosing device comprising a fluid conduit (100) with a flexible tube, said conduit having a first end (102) for connecting to a liquid reservoir and a second end (104), which is provided with an outlet. The inventive device is equipped with an actuating unit comprising a displacement element (108), whose travel is adjustable. Said element enables the volume of a section of the flexible tube to be adjusted in order to deliver liquid (130) in the form of separate drops or a separate jet to the outlet by the displacement of the displacement element (108) between a first end position and a second end position, the tube being partially compressed in the first or second end position. In other words, the invention discloses a microdosing device comprising a fluid conduit (100) with a section, along which a cross-section of said fluid conduit can be adjusted by an actuating device, to produce a modification in the volume of the fluid conduit. A ratio of fluidic impedance between the position of the actuating device and the outlet to a fluidic impedance between a first end of the fluid conduit and the position of the actuating device can be varied by modifying the position of the actuating device, in such a way that a dosed volume that is delivered to the outlet can be varied in this manner by at least 10 %.
