ABSTRACT The invention relates to a device for the transformation of a laminar fluid flow into drops, especially of infusion fluids, comprising an inlet unit 1 tightly placed into an intermediate unit 17. A cylinder 2 of the unit 1 is on its outer circumference provided with a screw-shaped channel 16 extending from a through-hole 15 leading perpendicularly to the cylinder 2 at its first side to the area of passage of the cylinder 2 into a bottom 8 at its second side. A step ?8 projecting radially inwards from the cylinder 1 8 comprises, on its inner circumference, a number of longitudinally running grooves 30 connected to a number of radially running groves 31 arranged on a flange 21 of the intermediate unit 17. A levelling nut 36 is screwed on a thread 5 of a socket 4 comprising a sealing screen 40 which is with a transition fit placed between the cylinder 2 of the unit 1 and the cylinder 18 of the unit 17. The number of drops per unit of time is adjusted by the rotating of the levelling unit 17. The number of drops per unit of time is adjusted by the rotating of the levelling nut 36, whereby a longer or a shorter screw-shaped channel 16 and, consequently, an accurate predetermined number of drops is achieved.
