ABSTRACT:
A device for transforming a laminar fluid flow into drops, especially infusion fluids, comprises an inlet unit tightly placed into an intermediate unit. A cylinder of the inlet unit is, on its outer circumference, provided with a screw-shaped channel extending from a through-hole leading perpendicularly to the cylinder at its first side to the area of passage of the cylinder into a bottom at its second side. A step projecting radially inwards from the cylinder comprises, on its inner circumference, a number of longitudinally running grooves connected to a number of radially running grooves arranged on a flange of the intermediate unit. A levelling nut is screwed on a thread of a socket comprising a sealing screen which, with a transition fit, is placed between the cylinder of the inlet unit and the cylinder of the intermediate unit. The number of drops per unit of time is adjusted by the rotating of the levelling nut, whereby a longer or a shorter screw-shaped channel 16 and, consequently, an accurate predetermined number of drops, is achieved.
