Abstract: Propellor system which is suitable for kinetic interaction with a fluid that flows unidirectionally through a channel, wherein the propellor system comprises a supporting body which is configured to be integrated within the channel in a fixed position, and a kinetic interaction system which is provided on the supporting body such that the kinetic interaction system extends in an interior area of the channel when the supporting body is integrated in the fixed position, wherein the kinetic interaction system is provided with cither at least one pair of rotatory blades, or a single rotatory blade, and wherein each rotatory blade performs a combinatory rotation.

Abstract: The invention relates to an apparatus and a method for simultaneous multiple medicine administration. The apparatus according to the invention comprises a housing in which at least two entry chambers and a collecting point are formed, wherein each entry chamber communicates with the collecting point via a flow path respectively and wherein in each flow path at least one penetration member is arranged, which causes a decrease in pressure downstream to the penetration member with respect to the pressure upstream to the penetration member. According to the method of the invention the independency of flow rates is eliminated irrespective of the equipment that is used, wherein a fluid is fed to a collecting point via separate flow paths and at least one penetration member is arranged within each flow path causing a decrease in pressure downstream to the penetration member with respect to the pressure upstream to the penetration member.
